Cost: Free for NYU Learners $250 for Non-NYU Learners Click Here to Register and Begin Module 1 The Clinical Case Presentation: 60-year-old male with a history of HTN and asthma. EMS Findings: Severe respiratory distress, SpO₂ in the 60s on NRB, HR 120, BP 230/180. Exam: Diaphoretic, diffuse crackles, warm extremities, pitting edema, and significant fatigue/work of breathing. Pre-hospital meds: NRB, Duonebs, Dexamethasone, and IM Epinephrine (under the assumption of severe asthma/anaphylaxis). Differential Diagnosis for the Hypoxic/Tachypneic Patient Pulmonary: Asthma/COPD, Pneumonia, ARDS, PE, Pneumothorax, Pulmonary Edema, ILD, Anaphylaxis. Cardiac: CHF, ACS, Tamponade. Systemic: Anemia, Acidosis. Neuro: Neuromuscular weakness. What is SCAPE? Sympathetic Crashing Acute Pulmonary Edema (SCAPE) is characterized by a sudden, massive sympathetic surge leading to intense vasoconstriction and a precipitous rise in afterload. Pathophysiology: Unlike HFrEF, these patients are often euvolemic or even hypovolemic. The primary issue is fluid maldistribution (fluid shifting from the vasculature into the lungs) due to extreme afterload. Bedside Diagnosis: POCUS vs. CXR POCUS is the gold standard for rapid bedside diagnosis. Lung Ultrasound: Look for diffuse B-lines (≥3 in ≥2 bilateral zones). Cardiac: Assess LV function and check for pericardial effusion. Why not CXR? A meta-analysis shows LUS has a sensitivity of ~88% and specificity of ~90%, whereas CXR sensitivity is only ~73%. Importantly, up to 20% of patients with decompensated HF will have a normal CXR. Management Strategy 1. NIPPV (CPAP or BiPAP) Start NIPPV immediately to reduce preload/afterload and recruit alveoli. Settings: CPAP 5–8 cm H₂O or BiPAP 10/5 cm H₂O. Escalate EPAP quickly but keep pressures to avoid gastric insufflation. Evidence: NIPPV reduces mortality (NNT 17) and intubation rates (NNT 13). 2. High-Dose Nitroglycerin The goal is to drop SBP to < 140–160 mmHg within minutes. No IV Access: 3–5 SL tabs (0.4 mg each) simultaneously. IV Bolus: 500–1000 mcg over 2 minutes. IV Infusion: Start at 100–200 mcg/min; titrate up rapidly (doses > 800 mcg/min may be required). Safety: ACEP policy supports high-dose NTG as both safe and effective for hypertensive HF. Use a dedicated line/short tubing to prevent adsorption issues. 3. Refractory Hypertension If SBP remains > 160 mmHg despite NIPPV and aggressive NTG, add a second vasodilator: Clevidipine: Ultra-short-acting calcium channel blocker (titratable and rapid). Nicardipine: Effective alternative for rapid BP control. Enalaprilat: Consider if the above are unavailable. Troubleshooting & Pitfalls The “Mask Intolerant” Patient Hypoxia is the primary driver of agitation. NIPPV is the best sedative. * Pharmacology: If needed, use small doses of benzodiazepines (Midazolam 0.5–1 mg IV). AVOID Morphine: Data suggests higher rates of adverse events, invasive ventilation, and mortality. A 2022 RCT was halted early due to harm in the morphine arm (43% adverse events vs. 18% with midazolam). The Role of Diuretics In SCAPE, diuretics are not first-line. The problem is redistribution, not volume excess. Diuretics will not help in the first 15–30 minutes and may worsen kidney function in a (relatively) hypovolemic patient. Delay Diuretics until the patient is stabilized and clear systemic volume overload (edema, weight gain) is confirmed. Disposition Admission: Typically requires CCU/ICU for ongoing NIPPV and titration of vasoactive infusions. Weaning: As BP normalizes and work of breathing improves, infusions and NIPPV can be gradually tapered. Take-Home Points Recognize SCAPE: Hyperacute dyspnea + severe HTN. Trust your POCUS (B-lines) over a “clear” CXR. NIPPV Immediately: Don’t wait. It saves lives and prevents tubes. High-Dose NTG: Use boluses to “catch up” to the sympathetic surge. Don’t fear the dose. Avoid Morphine: Use small doses of benzos if the patient is struggling with the mask. Lasix Later: Prioritize afterload reduction over diuresis in the hyperacute phase. Read More
Foundations of Amateur Radio Noise la la la la la hinders if I were a rich man effective a noise annoys an oyster communication but a noisy noise annoys an oyster more. Or said differently, when you're trying to communicate, something that the hobby of amateur radio does in spades, you'll need to deal with a phenomenon called noise. This noise comes in different forms, but the effect is the erection of barriers to successful communication. We refer to the impact of noise as a signal to noise ratio or SNR, the signal being the desired information, the noise the undesired interference. Expressed in decibels so you can deal with a massive range using a small number, an SNR greater than 0 dB means that the signal is stronger than the noise. Building a shack requires that you consider noise in many forms. If you've been a radio amateur for a few moments, your mind is likely to head straight for the hiss, crackle and pop you might hear whilst attempting to communicate on HF, but there's a few other things to discuss. There's all sorts of electronic noise received by your radio. In addition, there's audio noise picked up by your ears, and often your microphone. Then there's the noise that you produce, either from your transmitter into the rest of the building, or from your mouth or speakers into the ears of the people you share the space with. Starting with audio, having a space that you can close the door on is a good way to limit the noise coming into and leaving your shack. An alternative is to wear headphones and generate text to speech, or prerecord your voice, ready for a contact, potentially ideal for contesting, not so much for free form discussion. Another consideration is audio from other radios, including those tuned to a local broadcaster, or aviation frequencies. In other words, if you're transmitting with a microphone, make sure that there's no other audio coming through. In some cases it's even illegal to transmit that audio, but in all cases it's noise that makes communication more difficult. This kind of audio noise mitigation is pretty straightforward. In stark contrast, achieving the same with electronic noise is pretty much a balancing act between budget and effectiveness. The impact of noise is inversely proportional to distance. Essentially, the closer it is, the more impact it has. With that in mind, when you start dealing with noise, start nearby and work your way out. As you eliminate the nearby noise, other sources will become apparent. Without turning this into a noise mitigation class, the process is essentially one of elimination. First locate the noise source, then eliminate it. That's easier said than done. For example, if the noise source is a power supply sitting on your bench, you can turn it off, except if that power supply is the one powering your radio, so perhaps I should say: "attempt to eliminate it" instead. There's plenty of ways to have a go at this and volumetric kilotons of content published on the subject, some of it even useful. In many, but not all cases, noise is an electrical phenomenon that enters via any means possible and you'll need to attempt noise mitigation at multiple points of entry. Obvious sources are the power supply, coax and the antenna connection, the speaker cable, the microphone lead, and if you're using a computer, the USB, serial or Ethernet cable and within the computer itself. Each requiring different approaches. The obvious one is to disable the noise, that is, turn off the offending device. As I said, that might not be an option, but you can replace noisy gear, or place it further away. There's isolation, using tools like ferrites and chokes to stop the noise from reaching your radio. Often in the form of a clip-on blob, you'll find these on things like monitor and USB cables. Place the ferrite as close as possible to the input of your radio. If it's loose on the cable, wind it through the ferrite, the tighter the better. There's software solutions with varying levels of effectiveness. You'll find DSP or Digital Signal Processing knobs and buttons on many radios. They're generally helpful for narrowband repeating noises, like the hum of an electric motor or power supply. There's tools that attempt to impose a noise on your signal that cancels out the noise, anti-noise, if you like, by receiving the noise, inverting it and adding it to your signal, thus, at least theoretically, eliminating it, noise minus noise is silence. This can take the form of a device for noise coming in from the antenna, but it also applies to things like noise cancelling speakers. In audio this is called active noise cancelling. There's also a new crop of noise cancelling software, using A.I. or Assumed Intelligence, that captures your signal, attempts to figure out what's noise and what's not, removes the noise and then feeds it back to you. Your Mileage May Vary and if you break it, you get to keep both parts. Consider your privacy and security implications of sending your audio out the door to be processed. That's not to say that, at least theoretically, effective local Machine Learning models could be created to help with this. I have yet to see one. At some point you'll hopefully reach a place where the noise inside your shack is no longer an issue. Then you'll discover your noisy neighbours, with solar panel inverters, pool pumps, plasma televisions, broadband modems, kids toys and pretty much anything electronic, purchased with no consideration whatsoever in relation to your hobby. I'm mentioning this, because more often than not, you'll have little or no control of those devices. You could cultivate your relationship with your neighbours and discuss your situation, but don't expect compliant hardware to magically solve all your issues. Antenna orientation, horizontal versus vertical might assist, as might placement or distance from the noise source. It's why I suggest that you start this journey with simple antennas, with plenty of room for evaluation and modification to suit the conditions. All this to point out that once you have the perfect shack, your work is only just beginning, but then I suspect that you've already realised this. Like antennas, I will note that noise and its elimination is an integral part of this hobby. It's easy to forget that, whilst you're in the middle of a frustrating hunt for a noise source, and if you like you can think of it as ripples or waves on the pond whilst you're casting a fly. When you discuss this with other amateurs, you'll likely come across terms like QRM and QRN, the last letter describing either Man-made or Natural noise. I'm not sure how helpful the distinction is, but it's there if you need it. One resource worth mentioning is a website called qrm.guru. It has documented processes and tools to discover where noise is coming from and how to go about dealing with it. I'm Onno VK6FLAB

This show has been flagged as Clean by the host. Hello, again. This is Trey. Welcome to part 6 in my Cheap Yellow Display (CYD) Project series. Thank you for hanging in there with me on this rambling series. If you wish to catch up on earlier episodes, you can find them on my HPR profile page https://www.hackerpublicradio.org/correspondents/0394.html To review, my project is to build a portable morse code "Keyer memory" which can be connected to any of my amateur HF transceiver radios by simply plugging it in to the code key input port. This is based around an ESP32 platform which comes prepackaged on a yellow PC board with a color touchscreen display, WIFI, and Bluetooth. We fondly call this contraption the Cheap Yellow Display. So far, I have defined the necessities, collected the required hardware, and failed miserably building the graphical user interface (GUI). While I sort out the technical challenges getting my GUI code to play nicely with the CYD's touchscreen, it is important that we spend some time discussing Morse code itself, and the timing standards we will need to follow. I am not going to dive too deeply into the history behind telegraphs and Morse code, but it is very interesting. If you want to learn more, Wikipedia has the origins and evolution written out quite nicely at https://en.wikipedia.org/wiki/Morse_code For our purposes, we will fast forward from the year 1820 (When telegraphy began) all the way to 1865 when the International Telecommunication Union (ITU) standardized, what it called "International Morse Code". When I say Morse Code for the remainder of this podcast, I am referring to this ITU International Morse Code. Morse code typically includes the following characters: The 26 letter basic Latin alphabet The Indo-Arabic numerals 0 to 9 There is also a single accented Latin letter (É), which is written as an E with an accent mark, and a handful of punctuation marks. These characters are encoded using a sequence of short and long signals. Each short signal is referred to as a dit . Each long signal is referred to as a dah . At a young age, I began to refer to them as dots and dashes, as this is how they are usually written. For example, the letter "A" consists of a single dit followed by a single dah. When written out this would look like a period followed by a hyphen (what some might call a minus sign) .- This encoding method allows messages to be sent by turning on and off an electrical signal. This could result in a light flashing or a tone sounding to the pattern of the signal. The timing of a dit and dah, along with the spacing between them is carefully defined. Morsecode.world does a great job explaining the timing, and you can find their explanation at https://morsecode.world/international/timing/ It all starts with the dit, or more accurately, the amount of time the dit signal is turned on. We will call this length of time 1 unit. We will get to the actual length of time for a unit later in this episode. For now, it is just one unit. So, if a dit is 1 unit long, a dah will be 3 units long, so there is an obvious and consistent difference between a dit and a dah. Also, empty space between elements of the same character is 1 unit long. The space between characters should be 3 units long. Let's demonstrate using the letters H, P, & R. An "H" would be 4 dits …. A "P" would be 1 dit followed by 2 dahs and ending with 1 dit .--. An "R" would be 1 dit followed by 1 dah and ending with 1 dit .-. Remember when we send these grouped together like a word, we need 3 units of spacing between each character. You can hear this now. This is Morse code for the letters "HPR" at 15 words per minute .... .--. .-. That is the perfect segue to the next section, words per minute. The speed of morse code is measured in "words per minute". But how do you calculate this when some characters are short (Like the letter "E" which is only a single dit long), and other characters are long (Like the letter "J" which starts with a single dit and is followed by 3 dahs)? And that's just letters. What about words? We have short words and long words. How can we standardize on words per minute with so much diversity of length? Well, thanks to the French, we have a quite elegant solution to this problem. Well, not the French in general. Just PARIS. PARIS is the standard word which has been agreed upon to be used for determining the speed of Morse code. The word PARIS is 50 units long. "P" = dit(1) + (1) + dah(3) + (1) + dah(3) + (1) + dit(1) = 11 units {Space between letters} = 3 units "A" = dit(1) + (1) + dah(3) = 5 units {Space between letters} = 3 units "R" = dit(1) + (1) + dah(3) + (1) + dit(1) = 7 units {Space between letters} = 3 units "I" = dit(1) + (1) + dit(1) = 3 units {Space between letters} = 3 units "S" = dit(1) + (1) + dit(1) + (1) + dit(1) = 5 units {Space between words} = 7 units 11+3+5+3+7+3+3+3+5+7 = 50 units Here is the word PARIS sent at 15 WPM .--. .- .-. .. ... Morsecode.world again does a great job explaining the maths for how many milliseconds long a dit should be for a specific WPM of code ( https://morsecode.world/international/timing/ ) But, no... We could not keep it that simple. Some guy named Donald R. "Russ" Farnsworth had to complicate things and increase the gaps between letters and words to make interpreting code much easier. There are even more maths for Farnsworth timing... Wait a minute. When did I start saying "Maths" instead of "Math" like a normal North American? What is the reasoning around pluralizing "Math" anyways? Which way is more original English, "Math" or "Maths"? This sounds like a show idea for someone other than me. If you know or are interested in researching it, I look forward to listening to your show in the future. ANYWAYS, there IS much more MATH about Farnsworth timing on another page on Morsecode.world. ( https://morsecode.world/international/timing/farnsworth.html ). But I don't want to get into all of it in detail here. Not when there is a shortcut we can use in our code. Simplified, we can take 1,200 and divide it by the WPM we desire, and it will give us a close enough approximation of the number of milliseconds long a dit should be. For the 15 WPM messages you have heard throughout this episode, a dit was 1200/15 = 80 ms in length. If I speed it up to 20 WPM (The speed at which I try to practice) a dit will be 1200/20 = 60 ms long. This will be an important calculation for us as we develop the code we will later be using to construct our messages using the CYD. And this is also a good stopping point so that I can get back to trying to build that infernal GUI. Provide feedback on this episode.

Foundations of Amateur Radio One of the potentially trickier aspects of putting together your shack is connecting the radio to the antenna. On the face of it, the challenge is limited to making sure that you have mating connectors on both ends, but when you actually start implementing this you'll run into several other considerations. The very first one as I said is the connector. Every amateur I've ever spoken to goes through the same process. You pick a connector, typically the one that your radio comes with, then you adapt the connector on your coaxial cable to suit, then you'll get an SWR meter, a dummy load, some testing gear, a coax switch or two, perhaps another radio, or an amplifier and along the way you'll discover that you now have a growing collection of connectors to choose from, and that's just the connectors inside the shack. After considering connectors, you'll start to contemplate the coax itself. You'll likely weigh price against signal loss, but there are other aspects to the selection of the right coax for the job. For example, how do you get the coax actually into the shack? One of the main challenges associated with solving that problem is surprisingly something that rarely affects our hobby, other than any human factors associated with the phenomenon of "weather". Getting coax into a shack generally involves passing through a weather proof barrier of some sort. In doing so, you're likely to create a place where the weather can make its way into places it's not supposed to. Water can and will travel along your coax. Hopefully on the outside of it, but if you're unlucky, on the inside too, likely destroying it along the way. At first glance you'll think that water only travels down with gravity and in an ideal world you'd be right, but as it happens, water will happily do other things like get blown by the wind, or condensate in temperature gradients, like those found near a hole you just created in your lovely weather proof barrier. If your shack has existing openings, they're generally the easiest to appropriate, things like gaps in the eves, existing vent holes, between roof tiles or sheet iron, plenty of existing places where you can get from inside to outside a shack. Note that this is also the case if your shack is a trestle table tucked away in an office, like mine. Before I continue, I'm about to raise some potential safety issues, but I'm not an occupational health and safety professional, so, do your own due diligence. If you do need to go into your roof space, height aside, consider it a dangerous place. Make sure that there's someone to check on you and consider alternatives to climbing up there. Wearing a face mask and full body clothing is a very good idea. Often you'll find exposed wires, deteriorating or toxic insulation and other nasty things, conductivity of steel roof frames and pipes are also a hazard, so be extremely reluctant to venture there. Avoidance is preferable. Working at heights 101: Don't .. that said, there may be no alternative. You can lift corrugated iron sheets by undoing the roofing screws. If you do, make absolutely sure that you don't make a string of water inlet points when you put it all back together. In lifting a sheet, you can access the roof space and run your coax. Sometimes the gap between the corrugation and the rafters is sufficient to push the coax through, but if you live in a hot climate, make sure that it doesn't touch the sheeting, since coax is likely to distort, if not outright melt, if it's in direct contact with the iron sheet while the sun is belting down on it. Consider the temperature rating of your coax. Similarly, terracotta roof tiles tend to have enough space to allow coax to enter the roof space. Be very careful, since they're often fragile and potentially irreplaceable. Look for openings like existing roof fittings, things like chimneys, vent pipes, roof ridges, etc. for simpler points of entry. If you need to make a hole in your roof and seal it, there's special rubber grommets for this purpose. You cut a little opening in the grommet, too tight for the coax, then force it through. Seal to the roof with UV-stable silicone and you're good to go. Check them every so many years, they deteriorate. Speaking of silicone, if there's an existing hole that you're using, don't just seal it up, it might be there for a reason. Windows often have vent holes or gaps that will fit some types of coax and there's inserts you can use to open a sliding window that will accommodate coax, but consider the security of that window before you commit. There's also special flat coax for running through a window frame or under a door, but check before you buy that they're suitable for the job. Ladder line is also an option, it's much thinner, can travel longer distances, but its performance can be affected by corrugated iron and other conductors. Rarely if ever does the initial acquisition of coaxial cable involve details like "bending radius", the smallest turn you can make with the coax without destroying its characteristics, since bending causes the insulation, the core and the shield to distort to some degree and with it, affect the RF passing through. Whichever path your coax takes, consider that you can cut it short, but not long. If you really must know how long the coax is, use some string to run along the proposed path, but beware, the string has a bending radius that approaches zero, coax does not. Most coax will specify a bending radius for fixed and repeated bending. The fixed one is for a one time only bend and 65 mm is typical. Thinner coax tends to have a smaller bending radius, but that might affect the signal loss, or the budget, or both, so take that into account. Cutting and joining also introduces points of failure, places of moisture ingress, thick spots that cannot be pulled through existing holes, and plenty of other hidden fun and games, in other words, don't be stingy, get it right, it might cost a few bob extra, but you'll have a happier time of it. If you need to run your coax inside a wall, the tool you're looking for is called a "Cavity King", not of the embalming variety, though relevant if you happen to do something foolish like drill a hole through an existing power wire in your building, so don't start drilling holes where it suits without checking first. If you do, make sure that you drill on an angle facing upwards from the outside and find a place where the coax itself doesn't get wet on the way in. Speaking of holes. Terminate the coax after you installed it, not before. You can use electrical tape to attach a rope to pull the coax along its route without damaging the coax. Before you close up the roof and pack everything away attach the connectors to the coax and properly test it. If it fails your tests, it's easier to run it again with everything in place than it is to start from scratch, ask me how I know. In my shack, I have a run of RG-214 that goes to my VHF/UHF vertical, I also have a run of quad shield RG-6 that goes to my HF antenna. If you're familiar with coax indicators, you'll know that RG-6 is actually 75 Ohm, not 50 Ohm. Given that it's made from aluminium, not copper, it's also an absolute turd to solder. What it does have going for it is that it's absurdly cheap, since its used in satellite dish installations across the planet. It also very handily can be terminated with F-type compression connectors, which in the 25 years I've used them, I've yet to see fail. The F-type connector can accommodate a handy BNC adaptor, bringing us back into the realm of amateur radio. My coax goes under the corrugated iron of my roof through the plasterboard of my office wall, hidden away in a cupboard, snakes under the cupboard door, along the wall to the termination coax switch that is in turn connected to my radio, more on that another time. The two coax runs are tied together, to ensure that they don't coil weirdly, don't pose a trip hazard and it's connected to various fixed points along its path. None of it is permanent, other than the hole in the plasterboard, inside a cupboard, behind a faceplate. So, after removing the coax, a blanking plate brings everything back to invisible if that's ever required. What happens outside is a whole different story and what it attaches to, yet another. The point is that from the place of picking the right connector, you likely discovered that routing coax is potentially a bigger challenge than you might have considered at first. There are other options. What issues affect the ingress of coax at your shack? I'm Onno VK6FLAB

Go check it out and throw your name in the hat! What's up, elk hunters! This week on the Elk Hunt Podcast, I sat down with my buddy Jared Miller, and man, this conversation went deep. We started talking about rifle hunting versus archery hunting elk (spoiler: Jared thinks rifle hunting elk in Montana is way harder than bow hunting), and somehow ended up diving into the mental game of archery, bow tuning secrets, and his insane Matthews hunt that we filmed this fall. Jared's one of those guys who's just obsessed with the process - whether it's shooting Vegas rounds every single day, torque tuning his bow, or working through Joel Turner's shot control process. We get into all of it. He shares some wild stories from this season, including a two-day Montana archery hunt that turned into one of the best films we've put out, and breaks down exactly how he stalked to 20 yards on a bedded bull in socks. If you're into archery hunting, this episode is packed with gold. We talk about grip pressure, forgiveness in bow setups, the mental side of executing under pressure, and why Jared shoots 30-60 arrows a day leading into season. Plus, he drops some serious knowledge on open country elk hunting and what he's learned about where these bulls actually bed. This one's a bit different from our usual episodes - less tactical talk, more mental game and archery deep dive - but I think you're gonna love it. Let's get into it.Jared's Matthews Film - Immersion Tricer Tripods - These guys make gear that's fast, light, and simple. From incredible tripods to bino mounts, panheads, truck mounts, and now even bipods, Tricer has everything you need for better glassing setups. I've been running their bipod hard this season and killed a lot of critters with it. Head over to www.tricer.com and use code TRO to save 10% at checkout. Stone Glacier - My Sky Archer 6400 has been everywhere with me this year - Alaska, British Columbia, Wyoming, Montana.

The lesson: find what works for you and stick to it, especially when the pressure is on. Forgiveness Over Speed in Bow Setup - Instead of chasing maximum speed, Jared prioritizes forgiveness in his bow setup (shooting around 280-285 fps, lots of vane, torque tuning). He explains how you can find an "equilibrium" where your bow hits center even when you torque left or right - critical for real hunting situations when you're not perfect. Mental Reps Are Everything - Jared shoots 30-60 arrows a day, but not just for physical strength. He's training his mental process - getting comfortable operating in a state of awareness, managing shot anticipation, and executing controlled shots even when his pin is floating. He credits Joel Turner's process for helping him overcome severe target panic that had even started affecting his rifle shooting.
Foundations of Amateur Radio When you start on the journey of putting together a shack, in whatever form that eventually takes, you'll need to figure out how much space is required. Of course, no matter what you choose, it's never enough, but you have to start somewhere. Ultimately a shack is a work in progress. As an aside, I'm using the word "shack", but that is really an amateur concept, so we're not necessarily talking about a plot of land with a wooden lean-to cobbled together from bits of wood collected from your beachcomber days. Not that it can't be that, but it doesn't have to be. As I've said, my "shack" is a wooden trestle table, I know shacks that are a dedicated room in a house, a converted garage, a garden shed, a warehouse office, a radio station, an out building, several scout halls, demountables, a converted passenger bus and plenty more. In this context, in referring to "shack", I mean, "the place where my radio lives when I get on-air to make noise", but "shack" runs off the tongue a little easier. Budget aside, in order to attempt to quantify your space requirements, you need to figure out what you're going to do with it. This perhaps sounds a little ludicrous, since the answer is "amateur radio" .. duh .. obviously. Okay, so, here's some questions. Does amateur radio for you mean any of the following: operating the local repeater, HF radio, solo or with visitors, listening to multiple stations, operating multiple bands simultaneously, computers, Morse code, contesting, soldering, building, experimentation and plenty more. While we're at it, if you're into soldering, is that with valves, discrete components, or integrated circuits, and what levels of existing bits and pieces do you have? I'm asking because the racks of jars, component trays and drawers I've seen over the past fifteen years often rival the actual shack for size. In other words, when you're thinking about .. what .. you want to do, be specific. For me, amateur radio is more about computers and less about soldering irons, that's not to say that I don't own a soldering iron, just that its use is incidental, rather than fundamental, computers, keyboards and monitors on the other hand, for me, are part and parcel of my amateur radio experience. Truth be told, if I could, I'd try to eliminate all the analogue radios from my shack and replace them with a single box capable of wide band operation across the amateur bands that I could control with a computer. I realise that this is not a universal picture of what amateur radio means, but it's what it means for me because it represents the ultimate level of flexibility. That said, I love my FT-857d. I have several other radios that I loan out from time-to-time to new amateurs while they find their feet. I love to experiment with those as well, so my shack needs space for temporary set-ups. While I enjoy chewing the fat over a cup of coffee, I rarely get on-air and make noise with anyone else. That's not because I don't appreciate it, but because I've yet to discover an effective way of filtering interference, a topic for another day. Even if you're not a computer nerd like me, there's a high probability that a shack today includes a computer of some description, for record keeping, propagation forecasts, logging, and digital modes. So it's a good idea to imagine yourself actually doing your planned activities and speculating what kinds of things you'll need. Like, where do you put your cup of coffee, your keyboard and your Morse key? While we're discussing putting things down. Think about the ability to actually use these things, not just where they live. It's no fun balancing a keyboard and trying to reach over the top to change the operating frequency, or having to strain your neck to look at the logging screen when you've made that elusive contact, so think about the ergonomics of what you're planning. Right now I have a wire shelving unit sitting on my desk. It's 80 cm tall, 90 cm wide and 30 cm deep. The two shelves are adjustable in height. Currently one is at the highest point, the other has enough space to fit a base-station radio underneath it, about 13 cm from the lowest point. It's not ideal, since it means that the keyboard is in front of it. During the previous iteration, of which there have been several, my monitors were in front of this and the keyboard was an external one connected to a laptop to the right of the screen, allowing me to have two screens to display information. The idea was that I'd use the computer to control the transceivers using a protocol called CAT. This never happened, so operating was awkward to say the least and as a result, hardly used. Instead the FT-857d sat on top of the bottom shelf, using a sound card to operate on digital modes. A slightly better operating angle, were it not for the monitor that hid it from view. As I said, not ideal. I'm mentioning all this to give you a picture of at least one other shack but in my experience, nothing beats going out to see what others have gotten up to. Of course, you can visit shacks online with the proliferation of photographs proud amateurs have shared, but there's a difference between looking at a photo and walking around someone's physical shack, so keep that in mind. Other space considerations are rarely, if ever, talked about. What space is there left for you to make changes to your shack? You might think that your shack won't change once you've built it. Here's a change, disconnecting the antenna in case of a thunderstorm, here's another, plugging in a CAT cable, setting up an external speaker, or even buying a new radio, you name it, the shack is never done. So, think about the idea of being able to walk behind the radio. If you think that's silly, put the shack on wheels. You'll thank me later. While you're walking behind your equipment, consider coax routing, a topic of its own, but being mindful of the need to actually get the coax from where it enters to your gear and how it relates to any electricity routing required to actually power your gear. One other consideration in relation to space is your chair. How much space does it need? Can you adjust it, is it on casters, or a wooden dining chair? Again, this can all be as simple as a dining table, or it can be something more substantial. In my experience, a happier outcome is achieved if you spend some quality time thinking about some of the questions I've proposed. As you might have guessed, there's plenty more to explore.

Alright, so Jeremy Gilbertson is one of those guys who just went all-in on elk hunting—and it worked. This dude studied elk hunting harder than he studied school, killed a bull on his first-ever trip 36 hours from his front door in Minnesota, and then spent the next few years guiding hunters and building maps for a living. Now he's joining the Bridger Watch team to help us build the absolute best maps for wearables, because turns out everyone who said "nobody wants maps on a watch" was dead wrong. We dive deep into Jeremy's journey from cold-calling Colorado OTC units to guiding on private ranches in New Mexico, and we get into the real tactics that separate the guys who find elk from the guys who wander around hoping. We talk about e-scouting secrets, micro terrain, efficiency versus effectiveness, why busy is lazy (shoutout to Cal Arnold), and how to hunt like a 301 even if you're happy shooting raghorns. Jeremy's got a unique perspective because he's both a hardcore public land DIY guy and a guide who's seen hundreds of hunters make the same mistakes. If you want to learn how to find elk in tough units, how to balance aggression with patience, and why you need way more than seven days to figure out a unit, this one's for you. Let's get into it. $10,000 ELK HUNT GIVEAWAY We're partnering with Huntin' Fool Adventures for an insane giveaway. When you preorder a Bridger Reckon Watch and use code HF at checkout, you're automatically entered to win a $10,000 elk hunt voucher.

Jeremy's secret? Look for the smallest pockets where elk could survive, not where they want to be. That 50-acre hidden basin above the highway? That's where the pressure-educated bulls are living. When you're looking at a unit, turn off the public land layers and ask yourself: if I could hunt anywhere, where would the elk actually be? Then figure out how to access those spots legally. The micro terrain beats the macro highlights every single time. You Need Way More Than Seven Days to Figure Out a Unit - Outfitters operate on seven-day hunts because they've already spent years figuring out where the elk are and what they're doing. When you show up as a DIY hunter with seven days, you're spending the first five just learning what the guide already knows. Jeremy's rule: plan for 10-15 days minimum if you're hunting a new unit. The hard units? Budget 12+ days just to figure it out, then another 3-4 to actually execute. If you only have seven days, you're gambling that you'll figure it out faster than average—and most guys are packing out on the drive home with all the knowledge they needed on day one. Hunt Like a 301 Even If You're Happy Shooting Raghorns - The difference between a 201 hunter and a 301 hunter isn't the size of the bull—it's understanding the entire system. A 201 hunter finds a herd and focuses on that six-point. A 301 hunter understands where all the herds are, how they interact, where the satellites are coming and going, and how pressure moves elk across the entire unit. Here's the secret: if you hunt the nucleus where the big bulls are, you'll magnetize all the smaller bulls trying to be there too. Understanding macro herd dynamics doesn't just help you find giants—it puts you in position to encounter way more elk, period.
This show has been flagged as Clean by the host. Hello, again. This is Trey. Welcome to part 5 in my Cheap Yellow Display (CYD) Project series. If you are still listening to me ramble about this project, thank you. If you wish to catch up on earlier episodes, you can find them on my HPR profile page https://www.hackerpublicradio.org/correspondents/0394.html To review, My project is to build a portable morse code "Keyer memory" which can be connected to any of my HF transceiver radios by simply plugging it in to the code key input port. Then I could transmit stored messages by simply touching their specific icon on the touch screen. I also want to be able to program each macro individually from the graphical user interface (GUI). To do this, I need to learn how to build a GUI. Most of the CYD resources I have been referencing recommend using Squareline Studio for GUI development on the CYD. Sadly, Squareline Studio is not open source. If any of you have experience with a good, open source alternative to Squareline Studio, please record a show to help the rest of us. Squareline does have a free trial and a free single user / single computer license, which I am using for this project. It will run on Windows, Linux, and Mac. After watching several videos about using the CYD with Squareline, I started to outline the functionality I needed. Squareline provides a wide range of pre-configured boards and interfaces to choose from, in addition to widgets and controls which you can drag onto your screens, and it will automatically generate the supporting code in the background. The initial page needs to have the macro buttons, with labels for the message they will send when pressed. There also needs to be navigation buttons to move from one page to others. Another important page will be the configuration page, where the user can store the contents of each macro and set the speed at which code will be sent. I would like to have a keyboard page where the user can type a custom message and send it. I made a few GUI sketches on post-it-notes, then I installed Squareline Studio on my Ubuntu laptop to start designing. There is a bit of a learning curve. Even with guide videos, I found the user experience to be... challenging. Their own GUI leaves much to be desired. It was not designed to run on the laptop's screen size/resolution. I had to switch to a much higher resolution monitor and rearrange frames within the app itself in order to see many of the controls. Button size adjustments, alignments, and label text did not work quite as expected. Getting things sized and aligned properly took quite a bit of fiddling. The text displayed on a button is a separate object from the button itself, so I have had to put some thought into object naming so that I can write code which will change button labels dynamically. I am including some screenshots from Squareline for the interface I designed. One great feature is that you can define actions and conditions for objects in your project. For example, there are buttons on the left which will navigate to specific screens. I defined actions within Squareline, such that when the specific navigation button is pressed, it will change the button appearance to look like it has been pressed and will then scroll left or right to a specified screen. Actions were also valuable for the Speed (WPM) slider on the Config screen. When this slider is moved left and right, the GUI will change the actual number for WPM to the right of the slider. Next, there is a simulator function which can be used to test how well the GUI works. It took some trial and error, but I was able to build and successfully test, navigational actions and the WPM slider. As I was working on building the afore mentioned WPM slider, and thinking about the default words per minute of Morse to use, my ADHD interrupted me (As usual). I decided to change the default speed that I use for the Arduino Nano based Morse code practice keyer which I keep on my desk. You can learn more about this keyer in episode 3 of this series. And we will also discuss Morse code speed in a future episode in this series. The original code (As found on https://github.com/jmharvey1/ArduinoCPO ) specified 12 words per minute (WPM) as the default speed, with buttons to increase or decrease this. However, I am practicing at 20 WPM. Every time I turn on the practice set, I need to turn up the speed and guess when I am close to 20. I went ahead and opened the PracticeOscilator project in Arduino IDE and updated the wpm variable to a value of 20. No, you will not see this change reflected in my own GitHub repo because: A) I wanted to test it locally first B) 20 WPM may be a little fast for a default C) I do not use git the way that it is meant to be used, or the way I SHOULD be using it, with pull requests and all. Bad Trey. D) I was distracted ANYWAY, the reason I bring this up is that it is the first time I have used the Arduino IDE to program a board with this system since I upgraded from Ubunto 20.04 to Ubuntu 22.04. Try as I might, I was not able to get the Arduino Nano's USB port to be recognized in Linux so that I could upload the updated keyer code. I spent several days troubleshooting, using other Arduino devices, different USB ports, and different cables, all to no avail. If anyone has any recommendations, I am open to suggestions. So, I dug out my son's old Windows 10 PC and started again. I had to install the Arduino IDE, load all the necessary libraries, and my code from Github (Which I had to manually change once again, because I don't fully get git). Finally I was able to update the Arduino Nano with its new code, and it works perfectly. But this revealed the same problem for the CYD. I also could not get it to connect over USB to my Ubuntu system. Time to migrate the entire project to Windows. My next step was to install Squareline Studio on Windows. Here, I ran into another snag, as my trial license was only for one system, so I had to uninstall Squareline from Linux before I could activate the license on Windows. Did I mention that I would love to find an open source, free software product to use instead? If you know of one, please ping me or post a comment. I wasted more time trying to get the GUI project I had written on the Linux machine imported into Squareline on Windows, all the while thinking of improvements I could make if I started again from scratch. It would not load, and would not load. In the end, I started all over again. After much blood sweat and tears, my GUI code was working again, and this time in Windows. I was able to run it in the simulation mode and move from page to page successfully and also use the WPM slider. I exported the UI from Squareline, and I loaded the code it generated into a new project within Arduino IE. Now was the moment of truth. I followed instructions found on the Pang YouTube channel video [ESP32 + LVGL] Configuration input device rotary encoder ( https://www.youtube.com/watch?v=aGM6gu9OpbA ). I connected the CYD and uploaded the code. SUCCESS!! You can see my "Send" screen loaded perfectly! Now to try other screens. Wait. Drat. It does not seem like my navigation buttons work. Actually, it does not appear that the touch screen is responding at all. I spent the next several days trying to figure out what went wrong. I checked and double checked interrupt and configuration settings (Such as those described in another of Pang's videos, [CYD + LVGL] Configuration Cheap Yellow Display | Easy Guide ( https://www.youtube.com/watch?v=qmR-mjJVumU ). Nothing worked. I came to realize that I bit off more than I could chew, and I should NOT have started with such an ambitious project. Instead I should have started with a simple equivalence of "Hello World", where I could build and test simple functionality to make sure I knew exactly what I was doing, then expand on it. Lessons learned, and a good stopping point for this episode. I am open to your feedback on what you would recommend, what I should do differently, etc. You can post simple feedback as a comment or send me an email using the address in my HPR profile. As usual, if your feedback is more than a sentence or two, you might want to record it as an episode so that other listeners can benefit from it as well. Time for an espresso. Maybe I will make it a double. Or even a triple! Provide feedback on this episode.
Foundations of Amateur Radio Recently it occurred to me that I haven't been using HF in my shack for much longer than I'd care to admit. Over the years I've spoken about my shack and how it's set-up, more on that shortly. I effectively went off-air when I decommissioned the computer that was running tools like "fldigi" and "WSJT-X". Mainly because it was too slow, for example, taking a good minute to launch a copy of Firefox. After that I repurposed my HF antenna for use with my ultra low power WSPR beacon experiments and essentially ceased being a functional HF station. There's other forces at work, which I'll get to, but before I do, in discussion with a fellow amateur we discovered that my desire to get back on-air on HF is essentially the same journey that a new amateur might make and the idea was hatched to document the process and share it with you. In the past you've heard me say that the answer to most questions associated with amateur radio is: "it depends". As a new, or returning amateur, this might not be very helpful if you don't know what it depends on, so, I'm going to attempt to describe the process of determining how to get to the answers required to make a station. Now, before I start I'd like to talk about money. I'm raising this upfront because your access to a budget determines many of the choices that are open to you. You could interpret that to mean that you need money and while that helps, it's not universally true, in fact I'd go so far as to say that you could get on-air and make noise using nothing more than a mobile phone and an internet connection, which truth be told is pretty much the minimum requirement to enjoy my thoughts, so perhaps that's the base requirement. That said, even if you don't have access to that, there's other options that we'll no doubt explore together, so keep that in mind. I think that the very first thing to consider is what you think of when you hear the term "amateur radio". I've said it before and I'll say it again. Amateur Radio is a great many things to different people. For some it means a hand-held radio and chatting with mates on the local repeater, for others it means a full blown HF contest station with multiple antennas and radios, with integrated logging in a dedicated building. For others it means logging into a remote WebSDR and listening to the bands, decoding interesting signals, and license permitting, transmitting remotely across the internet. In other words, the "amateur radio" experience is unique to you. What you get from it is dependent on you and nobody else. As an aside, that's also true for licensing. If you have a "beginners" license, like my Foundation license, then it's entirely up to you to decide if and when you add extra privileges. "Foundations of Amateur Radio", well, its predecessor, "What use is an F-call?" emerged specifically in response to amateurs around me who continued to, let's be kind and call it "encourage" me to "upgrade" to a "real" license. Fifteen years on, I'm still a Foundation "beginner" and thus far I have yet to run out of things to do or talk about, so keep that in mind. I think that covers the disclaimers, no doubt more will occur to me as we continue on this journey. For the first decade or so of having a license, most of my activity was done in my car, a mobile shack of sorts. I didn't have access to a space where I could set-up a radio without running the risk of someone tripping over coax, or a landlord complaining within an hour of me erecting a temporary vertical. In other words, my mobile shack was born from necessity. It was helpful in exploring the limitless variation of operating positions, as-in locations and their impact on propagation, antenna performance, local interference, and plenty of other lessons. So, even if you don't have a permanent space to operate, there's plenty of amateur radio to go round. When I finally moved to a place where I had space, I started the process of putting together my shack. Initially it was pretty much integrated with my home-office. This sort of worked, but both the office and the shack suffered from this combination, so my first observation is that, in my experience, setting aside a dedicated space for a shack is a good idea. Now, right now, as I am telling you that, to the bottom right of my computer screen is the head of my Yaesu FT-857d, connected to a "RemoteRig", a pair of devices that replace the serial cable between the head and the radio with a network connection. The RemoteRig is connected to a WiFi router, which runs a dedicated wireless connection across the room to the WiFi router that's connected to the radio, sitting on what's left of my shack. It's how I run the weekly F-troop net. It's sitting there because I need to be able to access my computer to make log entries and track who's next in the round-robin discussion, and as I said, I've decommissioned my shack computer. Which brings me to the second point. Setting up a shack doesn't happen in isolation. You're likely to have existing infrastructure of some sort. It might be a fixed location for power points, it might be a previously drilled hole for incoming coax, it might be a bolted bench, whatever it is, it's something that you need to take into account. It's also something that you need to consider in terms of feasibility. Just because something is the way it is today, doesn't mean that it has to stay the same for the next decade. I've previously discussed the evolution of my shack, based on a 35 year old wooden IKEA trestle table, all of 1.2 square meters, complete with holes from taking it around Australia for several years in the back of a van. It's currently got a wire mesh shelving unit on top and a pegboard strapped to the back. The legs are adorned with power boards and as I said, the head of my radio is on the other side of the room. This all to say that building a shack doesn't happen in isolation. The local environment will determine what's possible and what's not. I'm not here to tell you what to do, I'm here to help you figure out what a shack looks like in your environment. Note that I've not talked in any way about what equipment to get, what, if any, antenna to install or what else is required. These are all part of the "it depends" and I'll talk about that soon.

This show has been flagged as Clean by the host. Hello, again. This is Trey. Welcome to part 4 in my Cheap Yellow Display (CYD) Project series. If you have hung in there with me so far on this journey, thank you. If you have missed earlier episodes, you can find them on my HPR profile page https://www.hackerpublicradio.org/correspondents/0394.html If you have questions, comments, concerns, or other feedback, please leave an episode comment, or drop me an email (Using the address in my profile). Even better, you could record and upload your own show which shares your viewpoint or expertise. To review, I finally have an actual project to build using the CYD. It is a portable, programmable morse code "Keyer memory" which can be connected to any of my HF transceiver radios by simply plugging it in to the code key input port. Then I could transmit stored messages by simply touching their specific icon on the touch screen. So, now I purchased a pair of CYDs. Each arrived in an anti-static zipper bag with a USB C cable, a 6 inch long 4 pin PB1.25mm to Dupont 2.54mm cable harness, a plastic case holding the CYD itself and a small plastic stylus. There are pictures in the show notes. Depending on how many IO connections I may need, and how I plan to power this, I am probably going to need more 4 pin PB1.25mm wired connectors. You can see a description of the various features and connectors on RandomNerdTutorials writeup about this board ( https://randomnerdtutorials.com/cheap-yellow-display-esp32-2432s028r/ ). The only difference I can see between this description and what I received is that mine have both a MicroUSB and USB C port. Of course, first thing, I had to plug it in and see what happens. It appears to be running some kind of simulation of a web site. The backlit display looks alright. It is not super high resolution, but for the price, it will suite my needs. The touch screen is responsive, but it is pressure sensitive and works best using the provided stylus or a fingernail and not your finger tip. So, I have the CYD. What other hardware do I need? I need to address how one of these will actually connect to my radios. Modern amateur radio transceivers which support continuous wave (CW) transmission (Which is another name for Morse code) generally can use one of two different pieces of hardware for input. The first is what we call a straight key. Below is a photo of the one I own. This is a classic, old fashioned telegraph style code key. It is designed to quickly and easily be pressed down to close a circuit and when released the circuit is opened, effectively making it a normally open push button switch. To send a dot, the operator holds down the key for a short period of time, then releases it. To send a dash, the operator holds down the key for a longer period of time, before releasing it. (We will discuss actual timing specifications for morse code in a future podcast) Connectivity for the switch has been standardized to use a 3.5 mm mono male phone connector which has only sleeve and tip connections. The second option is a paddle style electronic keyer. There are many styles of these, and I am including a picture of the one I use, which once belonged to a close friend of mine who is now silent key. In general, the paddle is two separate normally open switches. In the most common configuration, if an operator presses and releases the paddle on the right, a dash is sent. If the paddle on the right is held, a continuous series of dashes will be sent until that paddle is released. The left paddle works similarly. If it is pressed and released, a single dot is sent. If it is pressed and held, a series of dots is sent until it is released. The function of these paddles can be swapped from left to right using the radio configuration. There is additional functionality which can be configured in some radios for when both paddles are pressed simultaneously, but I am not going to describe those here. The paddle generally uses a 3.5mm stereo male phone connector with the sleeve being common. The tip of the phone connector is wired to the left paddle and ring of the connector is wired to the right paddle. Most modern radios have a built in keyer which can be configured for a paddle and will automatically transmit the dots or dashes at whichever speed is configured based on the paddle pressed. You can see this phone connector illustrated on Wikipedia's phone connector page. . https://en.m.wikipedia.org/wiki/Phone_connector_(audio ) You can learn more about all the various devices which can be used for sending morse and how they function at Morse Code World . https://morsecode.world/keys.html Ideally, controlling all the morse code timing within the CYD would be best. That way, it could be connected as a straight key and any keyer settings already configured within the radio shouldn't matter. However, If I wish to also be able to manually send morse code myself using my paddles, without disconnecting the CYD and reconfiguring the radio, that could be problematic. I may need to factor in the possibility of connecting my paddle to the CYD and then building in code to respond to inputs from the paddles. As I mentioned in a previous episode, I have an Arduino Nano on my desk as a practice oscillator for my paddles. I may be able to reuse some of that code on the CYD. So, if I want the CYD to appear to the radio like a straight key, I will need it to be able to control a switch quickly and accurately. But I also want the CYD and the radio to be electrically isolated from each other. This calls for a relay. I was able to find and order some inexpensive relay modules which work nicely with Arduino and ESP32. These allow connectivity to 5v power and to one of the CYD's GPIO pins. These feed an optocoupler circuit, which, in-turn, drives the coil of the relay. This provides inductive kickback protection to the CYD and can drive a coil which would require more current than the GPIO can provide. Inductive kickback rabbit trail: An inductor is simply a coil of wire. Direct current flowing through any wire generates a magnetic field. Within the inductor, because the wire is coiled, the magnetic field builds from each pass of the wire in the coil. If you include an iron core, it sustains the magnetic field even better. This is the basis for an electro magnet. A relay is simply a momentary contact switch controlled by an electromagnet. One unique property of an inductor is that, current wants to keep flowing in the direction it was applied. To be specific, when the current source is removed, the magnetic field still exists for a while, and it effectively "generates" an electric current within the coil, in the same direction as the one which initially created the magnetic field to begin with. If it has a path to flow, this current will create another weaker magnetic field, which creates its own electric current, in a diminishing loop. If the circuit which drives the coil of a direct current relay is not ready for this continued push of current, damage can be done. Many times this is countered by wiring a "flyback diode" in parallel with the coil and in the opposite direction in which current will be applied. This way, when the current source is stopped, the diode gives a path for the inductive kickback current to safely flow while the magnetic field dissipates. Explained in greater detail at https://inductive-kickback.com/2019/04/inductive-kickback-made-simple-to-grasp-easy-to-handle/ The switch side of the relay is a single pole double throw (SPDT) and makes connections available for common, normally closed (NC), and normally open (NO). It will be easy to connect the common and NO connections to a 3.5mm mono male connector so that it may be plugged into the "key" port on any radio transmitter. I will need to do some testing on the speed of the relay, but I think it will work just fine. Once I start writing some code for the CYD, I will be able to connect and test the relay. Well, this is a good place to end this episode, and it is one of the longest in this series so far. In the next episode, we will begin to look at how we design the user interface for our program, something I do not know anything about (yet). Stay tuned weekdays for additional exciting episodes of Hacker Public Radio, and, at some point, the next episode in this series.

In this episode titled “Ham Radio (Amateur Radio),” host Mike Dell reflects on his youth prior to the Internet and video games, mentioning his limited interaction with CB radio rather than ham radio. He explains the differences between CB and ham radio, particularly the wider range and more diverse frequencies available to amateur radio operators. Mike discusses the various frequency bands in ham radio, starting with UHF, VHF, and HF, detailing their uses and characteristics. He explains concepts like frequency modulation (FM) and amplitude modulation (AM), along with how repeater stations work to extend transmission ranges. Mike also recounts his personal experiences with these frequencies, mentioning how he engaged with fellow hams while fishing and discussing the unique phenomena of tropospheric ducting that allowed him to communicate long distances. He then dives into specific bands, starting with the two-meter band, explaining its popularity, accessibility for new technicians, and how equipment like inexpensive radios can enable communication across towns. Mike also shares anecdotes about his experiences and connections with other ham operators, emphasizing the camaraderie within the amateur radio community. Continuing, he describes several other HF bands, explaining each band's unique properties, propagation characteristics, and modes of communication available within them. Mike touches on historical aspects of obtaining licenses, mentioning how the requirements have shifted over the years, specifically noting the discontinuation of Morse code testing for access to ham radio. Additionally, Mike elaborates on various digital modes that have emerged within ham radio, contrasting them with traditional radio communication, and shares fond memories of his early experiences, such as using packet radio to send messages to his father before email became commonplace.

CardioNerds (Dr. Kelly Arps, Dr. Naima Maqsood, and Dr. Elizabeth Davis) discuss chronic AF management with Dr. Edmond Cronin. This episode seeks to explore the chronic management of atrial fibrillation (AF) as described by the 2023 ACC/AHA/ACCP/HRS Guideline for the Diagnosis and Management of Atrial Fibrillation: A Report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines. The discussion covers the different AF classifications, symptomatology, and management including medications and invasive therapies. Importantly, the episode explores current gaps in knowledge and where there is indecision regarding proper treatment course, as in those with heart failure and AF. Our expert, Dr. Cronin, helps elucidate these gaps and apply guideline knowledge to patient scenarios. Audio editing for this episode was performed by CardioNerds intern Dr. Bhavya Shah.

Pearls Review the guidelines- Catheter ablation is a Class I recommendation for select patient groups Appropriately recognize AF stages- preAF conditions, symptomatology, classification system (paroxysmal, persistent, long-standing persistent, permanent) Be familiar with the EAST-AFNET4 trial, as it changed the approach of rate vs rhythm control Understand treatment approaches- lifestyle modifications, management of comorbidities, rate vs rhythm control medications, cardioversion, ablation, pulmonary vein isolation, surgical MAZE Sympathize with patients- understand their treatment goals Notes Notes: Notes drafted by Dr. Davis. What are the stages of atrial fibrillation? The stages of AF were redefined in the 2023 guidelines to better recognize AF as a progressive disease that requires different strategies at the different therapies Stage 1 At Risk for AF: presence of modifiable (obesity, lack of fitness, HTN, sleep apnea, alcohol, diabetes) and nonmodifiable (genetics, male sex, age) risk factors associated with AF Stage 2 Pre-AF: presence of structural (atrial enlargement) or electrical (frequent atrial ectopy, short bursts of atrial tachycardia, atrial flutter) findings further pre-disposing a patient to AF Stage 3 AF: patient may transition between these stages Paroxysmal AF (3A): intermittent and terminates within ≤ 7 days of onset Persistent AF (3B): continuous and sustained for > 7 days and requires intervention Long-standing persistent AF (3C): continuous for > 12 months Successful AF ablation (3D): freedom from AF after percutaneous or surgical intervention Stage 4 Permanent AF: no further attempts at rhythm control after discussion between patient and clinician The term chronic AF is considered obsolete and such terminology should be abandoned What are common symptoms of AF? Symptoms vary with ventricular rate, functional status, duration, and patient perception May present as an embolic complication or heart failure exacerbation Most commonly patients report palpitations, chest pain, dyspnea, fatigue, or lightheadedness. Vague exertional intolerance is common Some patients also have polyuria due to increased production of atrial natriuretic peptide Less commonly can present as tachycardia-associated cardiomyopathy or syncope Cardioversion into sinus rhythm may be diagnostic to help determine if a given set of symptoms are from atrial fibrillation to help guide the expected utility of more aggressive rhythm control strategies. What are the current guidelines regarding rhythm control and available options? COR-LOE 1B: In patients with reduced LV function and persistent (or high burden) AF, a trial of rhythm control should be recommended to evaluate whether AF is contributing to the reduced LV function COR-LOE 2a-B: In patients with reduced LV function and persistent (or high burden) AF, a trial of rhythm control should be recommended to evaluate whether AF is contributing to the reduced LV function. In patients with a recent diagnosis of AF (
