A new study from Malaysia examined how prolonged exposure to 3.5 GHz and 24 GHz radiofrequency radiation -- frequencies used in 5G networks -- affects male reproductive health in rats. In this episode, I walk through the study's findings on testicular immune balance, gene expression changes, and sperm function. The researchers exposed rats to these frequencies for four hours daily over twelve weeks and measured multiple biological markers. What they found adds important context to the ongoing conversation about wireless technology and fertility.

Foundations of Amateur Radio In the middle of the night when insomnia rears its head, there are occasions when an idea sprouts that is still with me the next day. I imagined a spinning globe that shows ionospheric propagation and allows you to navigate around the world and experiment. Think the ionospheric equivalent of windy.com in 3D. To get to that point, I started off with the Australian Space Weather Forecasting Centre. I was on a roll when I discovered that under "HF Systems" it has a "Global HF" section with "Ionospheric Map", which, curiously enough, shows exactly what you'd expect. What surprised me was that below the map is an animation viewer that allows you to see the last three days in half hour increments. Excitedly playing with this I found myself locked out and on the phone to the Bureau of Meteorology. I suspect that someone didn't tell the people who configured their content delivery network that users might be loading a gross of images from their website in short order, or two gross, if you also look at the "T-Index Map", like I did. With no immediate solution on the horizon, I went on the hunt for other sources of maps and discovered the NASA/JPL-Caltech GUARDIAN project, described as near-real-time ionospheric monitoring software for natural hazards warning. Their website has a limited archive of daily videos showing how the ionosphere changes, which was exciting until I discovered that my computer wanted to download each one, rather than play them in the browser, so making lemonade, I downloaded all of last month, thank you "curl", used my favourite video editing tool, "ffmpeg", to combine them, then uploaded the result to my VK6FLAB YouTube channel for our enjoyment. What's fascinating to me is being able to see, for the first time, just how the ionosphere changes throughout the month. You can see where there's regular solar activity and where exceptions occur. I'll note that there's a few gaps, I suspect that the software behind the scenes at JPL had some outages, but what's there is what was available. Now for the interesting stuff. This data is not created by something monitoring in space at L1, or in orbit around Earth, it's created by ground stations scattered around the planet. GUARDIAN is based around the Global Navigation Satellite System or GNSS. The project, to give its full name, the GNSS Upper Atmospheric Real-time Disaster Information and Alert Network, uses the radio signals from the four navigation constellations, GPS, Galileo, BDS and GLONASS. Name aside, the project has some really interesting goals; objective one, the result of which you can see in the video or on the website, is to allow users to explore ionospheric perturbations, in other words, you can see how the ionosphere changes over time. This is achieved by some cool radio phenomena, specifically, two different GNSS carrier frequencies will show phase change as well as alter what's known as "pseudorange", the apparent distance between a satellite and a receiver, affected by among other things, the "Total Electron Content" or TEC along the signal path. What that means is that the satellite signal is directly and proportionally affected by what's happening in the ionosphere. As an aside, this phenomenon can impact your mobile phone navigation, more on that in a moment. In other words, if you can measure how the radio signals from a navigation satellite change, you can calculate what the ionosphere is doing along a direct line between the transmitter and receiver, in response to natural and man-made events on Earth. If that's not enough, remember, this is just the first objective, the second one is to automatically detect those changes, the third objective is to characterise potential natural hazards. Lots of words to say that the aim is to detect events like geomagnetic storms, tsunamis, earthquakes, volcanic eruptions, thunderstorms, not to mention explosions and rocket launches. You can explore some historic examples on the GUARDIAN website at JPL. You can also compare the current planetary geomagnetic index with what comes out of the GUARDIAN project. At this point you might wonder what the ionosphere has to do with tsunamis? As it turns out, a whole range of natural and man-made hazards impact the ionosphere due to significant displacements of air at the surface, and the project used historic hazards and ionospheric data to link the two, and in July 2025, the magnitude 8.8 Kamchatka earthquake and associated tsunami was automatically detected 30 minutes before it reached the coast of Hawai'i. If that doesn't hit you in the Wow spot, during my research I came across several projects that explore the use of mobile phone GPS receivers as sensors. There's billions of those, so potentially, planetary coverage. For comparison, in 2022 there were 80 Global Differential GPS ground stations powering GUARDIAN, today the network has over 200 sites. Google Research published an article in 2024 using the same methodologies to measure the ionosphere using millions of mobile phone GPS receivers, effectively doubling coverage. Their article in Nature goes into detail which devices were used and how, essentially, using anonymised and privatised Android location data. From an amateur radio perspective, it's interesting to note just how variable and dynamic the ionosphere is and what types of phenomena affect it. I also wonder if my PlutoSDR might be used to have a go, since we're talking about radio frequencies around 1.1 and 1.5 GHz. All the more reason to get on-air and make some noise and excite the ionosphere and a receiver somewhere on Earth. I'm Onno VK6FLAB

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 10th of September 2026. As we head into September, autumnal HF conditions are fast approaching. We can expect the maximum useable frequency, or MUF, to climb during the day and DX to become more plentiful. However, we are not there yet and it may take a few more weeks before we see much of a change in HF propagation. Meanwhile, solar activity remains quite low, with a solar flux index around 100 to 110. Geomagnetic disturbances are still occurring, but their effects have been minimal. The Kp index rose to 5 on the 8th of September, due to the effects of a coronal hole stream. Luckily, this was short-lived and the following day the Kp index was back to being in the 2 to 3 range. The last four days have seen only minor C-class flares but, with seven sunspot groups visible leading to the risk of solar flares and associated coronal mass ejections, activity remains quite high. MUFs over a 3,000km path have reached 24.9MHz at times, although the 17 and 15m bands have been more usable. Expect the daytime MUF to climb to perhaps 28 or 29MHz by the end of the month. Two coronal holes appear to be developing on the Sun and will become Earth-facing today, the 13th, so there could be a coronal high-speed stream hitting us between tomorrow, the 14th and Wednesday the 16th of September. DX to be worked next week includes RI1FJZ from Franz Josef Land; V47YA and V47RCX on St Kitts and Nevis, KH8WW from American Samoa; and S79/DL2SBY from the Seychelles. Also, look for PJ2/K5SL from Curaçao from the 18th of September and 8Q7JH in the Maldives from the 20th of September. Next week the Space Weather Prediction Centre forecasts that the solar flux index may remain in the 105 to 115 range. We can expect unsettled geomagnetic conditions from the 14th to the 16th of September. This is possibly due to the coronal hole activity mentioned earlier, with a predicted Kp of 4. Otherwise, the rest of the week may remain calm with a Kp index of 2 to 3. And now the VHF and up propagation news from G3YLA and G4BAO The current spell of changeable autumnal weather looks likely to remain with us for most of the coming week. However, the UK covers a broad span from south to north and some differences will be apparent. We have seen the arrival of some fronts with rain in the south. These will probably be weaker than in northern Britain and with only occasional patches of rain. For the rest of the time, look out for weak ridges of high pressure and periods of tropo into the near continent and possibly south across Biscay to Spain. For the northern half of the country, the weather systems will be more active and tropo will be less likely, but you could find some occasional rain scatter opportunities on the GHz bands. Meteor scatter options are still only available via random activity with no major showers playing a role. The aurora prospects are probably not zero, but recently alerts have been for minor levels of disturbance with a Kp index up to 5, but nothing dramatic on the radio aurora front. However, with it now being autumn, it is always worth monitoring. As we head towards the autumnal equinox on the 23rd of September, it is a good time of the year for aurora if the triggering solar activity is sufficiently strong. EME now, and Moon declination continues to fall until its lowest point around Friday the 18th of September. Meanwhile, path losses continue to rise until apogee, the Moon's furthest point from Earth, also on the 18th of September. Sky noise remains low and then rises again around Friday the 18th and Saturday the 19th of September, when the Moon is in Sagittarius. And that's all from the propagation team this week.
New research from Turkey reveals that WiFi-frequency radiation exposure during pregnancy may cause thyroid damage that persists long after birth. In this episode, I walk through a carefully controlled animal study that exposed pregnant rats to two point four five gigahertz radiation -- the same frequency your WiFi router uses -- and then examined their offspring's thyroid glands one full year later. The findings suggest prenatal EMF exposure may have consequences that extend far beyond pregnancy itself. I'll explain what the researchers found, why the thyroid matters so much, and what this means for expectant parents today. In This Episode How prenatal WiFi exposure affected thyroid structure one year after birth The specific types of cellular damage researchers documented Why the developing thyroid is particularly vulnerable to EMF One practical step expectant parents can take today Featured Study Read the full study: One-year follow-up of thyroid status in rats exposed to 2.45 Ghz radiofrequency radiation during the prenatal period See all studies at shieldyourbody.com/research
A new study reveals how wireless radiation at frequencies used by 5G and older networks may be affecting male reproductive health in ways we're only beginning to understand. In this episode, I break down recent research examining how prolonged exposure to 3.5 GHz and 24 GHz radiofrequency radiation—the frequencies used in modern wireless networks—affected testicular function, immune response, and sperm quality in laboratory rats. The findings add to a growing body of evidence linking EMF exposure to reproductive health concerns. In This Episode What researchers found when they exposed rats to 5G-range frequencies for extended periods How wireless radiation may trigger immune system changes in reproductive tissue The connection between EMF exposure and declining sperm quality documented across multiple studies One practical step you can take today to reduce unnecessary exposure Featured Study Read the full study: Prolonged 3.5 GHz and 24 GHz RF-EMF Exposure Alters Testicular Immune Balance, Apoptotic Gene Expression, and Sperm Function in Rats See all studies at shieldyourbody.com/research

News: Apple TV Hikes Prices SVS Releases SoundPath Multi-Band Wireless Audio Adapter Roku ups premium hardware with launch of its first OLED TVs Sonos Welcomes Beam Ultra and Sonos Ace Ultra to its System Ara's New Setup First Impressions Starlink Performance - We had no issues while we were in TN. The entire week no said anything about slow speeds and our streaming was no different than when we are in CA. I tested speeds from time to time and results varied but the slowest speed (22 Mbps) never impacted TV viewing. Ubiquity Network Management - this is a different world! I am still exploring all the things you can do. But the system is setup like a business. You have a network and wireless access points. I have four. One on Channel 11, two on 6, and one on 1. It was setip so the channels are far apart and don't overlap. MyQ & Honeywell (matter compatible) thermostats go offline from time to time. I restart the wifi access point and they come back. Third Reality Garage Door Opener - 2.4 GHz, Scene Management Mantel Mount MM815 Motorized Drop Down & Swivel TV Mount - $700 The MM815 is a remote-controlled drop-and-swivel TV mount. Press one button to lower the TV to eye level and rotate it as needed. It comes with an RF remote, is silent, and has two memory presets. Sony BRAVIA 7 II PRO True RGB 4K HDR Google TV with Gemini (Model Number K75XR70PRO)- $2300 The Sony BRAVIA 7 II PRO is Sony's 2026 mid-range True RGB Mini-LED TV (65 inches and up) with independently driven red, green, and blue backlight LEDs, XR processing, and about 2,000 nits of peak brightness for stronger color volume and contrast than a typical white Mini-LED. It is 4K at 120 Hz, supports Dolby Vision and Dolby Atmos, and has HDMI 2.1 gaming features (VRR, ALLM, 4K/120). Google TV includes Gemini for voice search and recommendations, plus AirPlay 2. The Pro bundle adds a three-year replacement warranty, a backlit rechargeable remote, extra Sony Pictures Core credits, and an enhanced Voice Zoom 3 dialogue mode; picture hardware is the same as the standard 7 II. Sonos Arc Ultra - $1099 The Sonos Arc Ultra supports Dolby Atmos that has a 9.1.4 driver layout and Sound Motion woofer to produce wide, height-enhanced surround and stronger bass from a single bar. It connects to a TV with one HDMI eARC cable, supports Wi-Fi, Bluetooth, AirPlay 2, and the rest of the Sonos ecosystem (including optional Sub and rear speakers), and can be controlled with the TV remote, Sonos app, touch controls, Sonos Voice Control, or Alexa. Trueplay tunes the sound to the room, and AI speech enhancement is meant to keep dialogue clear. It is a long, low-profile bar (about 46 inches wide) sold in black or white. Sonos Sub 4 - $899 The Sonos Sub 4 is a wireless subwoofer for Sonos S2 systems, pairing with current soundbars and speakers to add bass down to about 25 Hz. Two inward-facing 5-by-8-inch woofers and dual Class-D amps use a force-canceling layout so the cabinet stays relatively still and the bass stays clean. It has the same slot-style shape as earlier Subs, in black or white matte, and can stand upright or lie on its side. Updates over the Sub 3 include Wi-Fi 6, a faster processor, more memory, lower idle power, and a slightly lighter cabinet; setup is through the Sonos app, with optional Ethernet. Two Sub 4s can be used with the Arc Ultra. Audio Advice - I'll be in Franklin in October for a SVS/Audio Advice Event. Details to come

Secure your place via rsgb.org/convention National Coding Week is back this month! To support radio amateurs in building their digital skills and explore the world of programming, the RSGB has shared three new activities for you to try. The first builds on the Python Pocket Morse activity developed last year and guides radio amateurs to use a BBC Micro:bit to send Morse code either on a telegraph wire or wirelessly. The second is ‘Ener-G use' which is great for unlicensed and younger radio amateurs and allows them to compare increasing forces and energy use with a fun Micro:bit activity. The third activity is based on the Raspberry Pi Pico 2W. It is a demonstration of Pulse Width Modulation and uses just a couple of components, including an LED and a resistor, and will give you a better understanding of the concept of duty cycle. All three activities are available via rsgb.org/coding You can try them at home, set up a practical club night or use them as an activity with a youth or school group.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 3rd of September 2026. Solar activity has continued to decline, leaving us with a solar flux index around 100. The upside is we haven't had any solar flares and associated coronal mass ejections, or CMEs, to contend with. Over the last week, we had only one M-class flare and no X-class events. The solar flux index declined to 102 on Thursday the 3rd of September – down from 122 a week ago. But the Kp index has been firmly in the range of 1 to 2 which bodes well for ionospheric stability. This has led to maximum useable frequencies, or MUFs, over 3,000km being around 21 to 24MHz. However, FT8 has stretched this up to 28MHz at times. There have been some good 10m band FT8 openings to South America late in the afternoon. Chile, Brazil and Argentina were workable during these periods. DX to be worked this week includes 3W9C from Vietnam; T99PB from Palau; Z68PX in Kosovo; P29YY in Papua New Guinea; HP/WE9G from Panama; D44TWO from Cape Verde; T32AZ from East Kiribati; and J38DX and J38LD operating from Grenada. V47YA and V47RCX from St Kitts and Nevis will be active from the 8th of September until the end of the month and KH8WW, in American Samoa, will be on the air from the 10th to the 24th of September. Two rare ones to look for are VK0DS from Davis Station and VK0TBC from Casey Station, both in Antarctica. Operations are mostly using SSB and FT8, as time permits. Both stations have been spotted on the FT8 frequencies of the 20, 15 and 10m bands at times. Next week NOAA predicts that the solar flux index will remain around the 100 mark. However, the good news is that, barring any flares or CMEs, the Kp index should remain low, perhaps around 2 all week. And now the VHF and up propagation news from G3YLA and G0KYA. The weather remains in a rather unsettled state. However, there are some signs of a transient area of high pressure brushing past the south of the country today, the 6th. This may create a chance of some tropo into the continent. This could tie in very well with the RSGB 144MHz Trophy and Backpackers Contests, which are taking place today the 6th. The unsettled pattern returns for the rest of the week and may not provide much help for the RSGB 432MHz UK Activity Contest on Tuesday the 8th, or the RSGB 50MHz UK Activity Contest on Thursday the 10th. In occasional bursts of heavier rain there may be some potential for rain scatter on the GHz bands. The prospects of meteor scatter remain in the random territory. So, it is best to listen just before dawn for the better chances. The solar conditions have not been very dramatic lately with the Kp index staying below 3. However, if it perks up a bit, say above 5, there may be a chance of aurora. The Sporadic-E season has more or less ended now. The next period to consider checking usually comes at the end of the year, and the first week in January, for out-of-season surprise openings. EME now, and sky noise should remain low during the coming week. Moon declination remains high. The Moon reached perigee, its closest point to Earth, yesterday, the 5th, so path losses remain low. And that's all from the propagation team this week.

Last week we said there were no coronal holes to threaten HF propagation. However, guess what appeared just after the time of writing. Coronal holes can appear at any time, which is why we recommend going to solarham.com for daily updates. This week another coronal hole has appeared and this one really does look like it could threaten Earth. This, coupled with coronal mass ejections, means that today, the 30th, could see the Kp index rise and maximum useable frequencies, or MUFs, fall. On a brighter note, the Kp index has been very low this past week, mostly below 2, with the result that HF propagation has been very good. Top DX being worked includes RI1FJL on Franz Josef Land in the Arctic Circle, which has been loud on many bands, right up to the 12 and 10m bands. Other DX to be worked in the coming week includes V5/HB9BFM from Namibia; J38DX and J38LD from Grenada; and P29YY working from Papua New Guinea. A quick check of the NCDXF beacon chain revealed very good propagation on 14MHz and 21MHz. This includes reception of the following beacons: CS3B in Madeira; RR90 in Siberia; 4S7B in Sri Lanka; 4X6TU in Israel; and 4U1UN in New York. So, it looks like we are starting to leave the summer doldrums and entering better autumnal HF conditions. Next week NOAA predicts that the solar flux index will be around 120, falling to 90 as the week progresses. After the potential for geomagnetic disruption this weekend, ending today the 30th, the forecast is good with a Kp index of around 2. And now the VHF and up propagation news from G3YLA and G4BAO The weather has changed to autumnal conditions with lows bringing periods of rain or showers and quite windy conditions at times. The coming week will turn out in similar fashion and means that we won't be dealing with much, if any, tropo for VHF. The main weather-dependent mode will be rain scatter for GHz band operators. The chances of aurora will need to show a Kp index above 5 to be of much interest, and probably a bit higher for southern areas. The prospects for meteor scatter are likely to be reduced to random activity which tends to give better results in the early morning hours before dawn. Lastly, we are coming to the close of the Sporadic-E season and, with probably a week or so to play out, any openings will be few and far between. Try checking during the main operating windows of mid-morning and late afternoon. As a back-up, consider the middle of the day since towards the edges of the season the traditional timings are less reliable. For EME operators, Moon declination went positive again yesterday, the 29th, with increasing peak elevation and lengthening Moon windows. Path losses are falling all week towards perigee on Sunday the 6th of September. 144MHz sky noise is low, increasing to medium by Friday the 4th of September. And that's all from the propagation team this week.
A new study reveals that just five days of WiFi-frequency exposure triggers measurable oxidative stress and early cell death markers in developing brain tissue. In this episode, I walk through a January twenty twenty-five study that exposed developing chick embryos and human brain cells to two point four gigahertz radiation -- the exact frequency your WiFi router uses -- for four hours daily over five days. The findings show clear biological effects at the cellular level, but also something unexpected: antioxidants helped reduce the damage. I explain what this means for your daily exposure and share one practical step you can take today.

Send us Fan MailRecorded live from a hotel room — Jim found something in the field worth bringing straight to the podcast. This episode covers 6 GHz beacons, and specifically what happens when an AP's primary channel isn't set to a Preferred Scanning Channel (PSC).Jim walks through the basics of the 6 GHz channel plan — 59 total channels, only 15 PSCs — then digs into the actual discovery: a misconfigured AP will beacon on multiple channels at once (1, 5, 9, 13), using a "duplicate beacon" flag to point clients toward the real primary channel. Jim didn't believe it at first, so he pulled his own PCAPs to confirm it, and shows the correctly configured vs. misconfigured captures side by side.Topics covered:6 GHz channel plan basicsPreferred Scanning Channels (PSCs) and why they existWhat happens when your primary channel isn't a PSCThe "duplicate beacon" flag, explained via real packet capturesQuestions?

It is the one with Bell's theorem in it. Maudlin traces how David Bohm's reframing of EPR using particle spin opened the door for Bell's 1964 proof, walked through step by step with a simple chart of coin flips: any theory ruling out "spooky action at a distance" must be deterministic, and no such local theory can match quantum mechanics's actual statistics. We cover common misreadings of Bell — that he assumed determinism (he didn't) and that his "free variables" require free will (they don't) — and close with the 1989 GHZ experiment, a cleaner, fully deterministic version of the same proof. Along the way: why Einstein's real objection was locality, not indeterminism, and why Maudlin calls the death of locality the most astonishing proof in the history of physics. Part Three is still to come. Stay tuned.

Turkish researchers discovered that WiFi exposure during pregnancy caused thyroid damage in offspring that persisted for an entire year after birth—suggesting prenatal EMF exposure may have lifelong consequences. In this episode, I walk through a new animal study that exposed pregnant rats to WiFi-frequency radiation throughout pregnancy, then examined their offspring's thyroid glands one year later. The findings reveal significant structural damage, increased cell death, and DNA breaks that didn't heal over time. I explain what this means for pregnant women using wireless devices and share one key step you can take today. In This Episode Why thyroid health during pregnancy matters for lifelong development What researchers found one year after prenatal WiFi exposure The biological mechanisms behind persistent thyroid damage One practical step for reducing prenatal EMF exposure Featured Study Read the full study: One-year follow-up of thyroid status in rats exposed to 2.45 Ghz radiofrequency radiation during the prenatal period See all studies at shieldyourbody.com/research

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 20th of August 2026. Last week was characterised by geomagnetic disturbances, due to high-speed solar wind streams from coronal holes, and a slightly increasing solar flux index. The Kp index hit 5 on the 18th and 19th of August reducing maximum useable frequencies, or MUFs, and generally being detrimental to HF propagation. We also had more than 50 C-class solar flares and one M-class event this past week, so nothing too severe. It was coronal holes that did the damage with two large areas on the Sun. A coronal hole is an area of the Sun with open magnetic field lines that allows solar plasma to escape. HF conditions were relatively poor during International Lighthouse and Lightship Weekend on Sunday the 16th, with little DX and heavy QSB or fading. The MUF struggled to get to 21MHz and most activity was on the 40 and 20m bands. Some transatlantic signals were logged, but they were weak and watery. That didn't stop people from enjoying the event though! DX to be worked this week includes 3B8/SQ9UM from Mauritius; RI8KR from Asiatic Russia; RI1FJL operating from Franz Josef Land; V47JA on St Kitts; and V51WH and V55Y active in Namibia. Good news this week as Propquest is back online, showing near real-time MUFs over various distances. Jim, G3YLA says this is a temporary fix pending further work. NOAA predicts that we will see a solar flux index around 100 to 120 next week, with relatively poor geomagnetic conditions forecast for today, the 23rd. The Kp index is predicted to be around 2 during the coming week. At the time of writing, there are no coronal holes threatening HF propagation, but keep an eye on solarham.com for updates. We are still analysing the eclipse experiment data, but a video of the 80m WSPR contacts has been produced and can be found at tinyurl.com/80mWSPR And now the VHF and up propagation news from G3YLA and G4BAO The return of unsettled weather last week pauses over this weekend, ending today the 23rd, as a new high moves across the country from the Atlantic. This gives a good chance for some tropo and, if the land temperatures pick up again and drift offshore, it could produce some good conditions across sea paths like the North and Irish Seas. Before mid-week, probably during Tuesday, low pressure will return and push a frontal system across the country followed by further fronts and showery periods for the rest of the week. This could be very good for rain scatter on the GHz bands, especially if the showers turn thundery. Meteor scatter will be largely random activity for most of the coming week. We will also see the end of the Delta Aquarids today, the 23rd , and the final trailing off from the Perseids, which end tomorrow, the 24th. The solar conditions are worth monitoring after recent activity saw the Kp index reach 5 on Tuesday and Wednesday last week. Ideally, we require something a little higher to start considering auroral propagation from the southern UK. Sporadic-E can last into the first week of September but tends to become harder to find and shorter in duration. There is no reason to stop checking though; anytime from mid-morning to late afternoon should cover it. For EME operators, the Moon was at apogee and at minimum declination yesterday, the 22nd. With minimum peak elevation and maximum path losses, it's a good excuse to check out the mechanics of your antenna. 144MHz sky noise is very high today, the 23rd, falling back to low as the week progresses. And that's all from the propagation team this week.
Declining sperm counts have become a global health concern -- and a new study suggests wireless radiation might be part of the story. In this episode, I break down a recent animal study examining how prolonged exposure to three point five gigahertz and twenty-four gigahertz radiofrequency radiation -- the frequencies used in five G networks -- affected testicular function, immune balance, and sperm quality in rats. The findings raise important questions about how our increasingly wireless world might be impacting reproductive health. In This Episode What researchers found when they exposed rats to five G frequencies for eight weeks How radiofrequency radiation may disrupt the delicate immune balance in testicular tissue Why these findings matter for anyone concerned about fertility and reproductive health One practical step you can take today to reduce unnecessary exposure Featured Study Read the full study: Prolonged 3.5 GHz and 24 GHz RF-EMF Exposure Alters Testicular Immune Balance, Apoptotic Gene Expression, and Sperm Function in Rats See all studies at shieldyourbody.com/research
A new study shows that just four hours of daily WiFi exposure triggered measurable oxidative stress and early markers of cell death in brain tissue — and it happened in just five days. I'm R Blank, and in this episode of the Healthier Tech Podcast, I walk through what researchers discovered when they exposed developing brain cells to two point four gigahertz radiation — the exact frequency your router, Bluetooth devices, and smart home gadgets emit continuously. The findings challenge the assumption that short-term exposure is harmless, and I'll share one practical step you can take today.

A new study reveals that WiFi exposure during pregnancy causes thyroid damage in offspring that persists for at least one year after birth -- raising urgent questions about prenatal EMF exposure. In this episode, I walk through groundbreaking research from Turkish scientists who exposed pregnant rats to two point four five gigahertz radiation -- the same frequency your WiFi router uses -- and then examined their offspring's thyroid glands one full year later. What they found challenges the assumption that prenatal EMF effects are temporary. The exposed offspring showed significant thyroid tissue damage, increased cell death, and DNA breaks that were still present a year after birth. In This Episode Why this study tracked thyroid health for a full year after prenatal WiFi exposure The specific types of thyroid damage found in exposed offspring What DNA double-strand breaks tell us about lasting biological harm Simple steps pregnant women can take to reduce EMF exposure Featured Study Read the full study: One-year follow-up of thyroid status in rats exposed to 2.45 Ghz radiofrequency radiation during the prenatal period See all studies at shieldyourbody.com/research
NR+, aka DECT-2020 NR, is a non-cellular 5G wireless technology standard that operates without cell towers or operator subscriptions. It offers private, highly scalable mesh connectivity in the license-exempt 1.9-GHz frequency band for such applications as industrial IoT and industrial automation. That said, other long-range standards offer similar connectivity. So the obvious question for me is, “Why do we need NR+?” To answer that question, I spoke to Nick Dutton, a Strategic Advisor to Last Mile Semiconductor. Nick answered my question, and lots more along the way, in this week's Embedded Executives podcast.

In this episode of Wavelengths, the Amphenol Broadband Solutions podcast, host Daniel Litwin continues his conversation with PJ Jayawardene, CEO and Founder of Consult Systems, diving deeper into the practical strategies service providers can use to respond to mounting network demand without relying solely on expensive, long-term infrastructure rebuilds.As broadband operators face increasing pressure from bandwidth growth, customer expectations, AI-driven traffic patterns, and competitive market dynamics, the traditional “rip-and-replace” mindset is becoming harder to justify. Instead, many providers are being challenged to maximize the value of existing assets, extend the lifespan of current infrastructure, and pursue targeted upgrades that create meaningful business outcomes while preserving future flexibility.In Part 2 of this discussion, Jayawardene explores where operators can find the highest-impact opportunities for network improvement, why higher-frequency deployments require a new level of operational discipline, and how lessons from hyperscale and AI infrastructure can help shape the next generation of broadband networks. Most importantly, he reframes network upgrades as business decisions—not just engineering decisions—arguing that successful operators will be those that create customer loyalty through reliability, incremental innovation, and thoughtful infrastructure investments. Key Discussion Highlights:• Start Where Density Creates Opportunity: Jayawardene recommends focusing first on densely populated residential markets and high-value enterprise environments where demand is strongest and competition is fiercest. These areas provide the greatest opportunity to generate revenue quickly while validating upgrade strategies before broader deployment.• Plan Beyond the Next Upgrade Cycle: Rather than solving for the next capacity milestone alone, operators should build upgrade roadmaps that accommodate future growth. The discussion highlights how technologies such as higher-frequency coax, DWDM, and coherent optics can be layered incrementally to extend the useful life of existing infrastructure while preparing for future demands.• Network Evolution Doesn't Have to Be All-or-Nothing: One of the central themes of the episode is that broadband upgrades are rarely binary choices. Existing fiber, coax, and optical infrastructure can often coexist with newer technologies, allowing operators to pursue targeted improvements rather than disruptive full-scale replacements.• Higher Frequencies Demand Greater Precision: Moving toward 4 GHz, 6 GHz, and beyond creates new opportunities for capacity expansion, but it also introduces stricter engineering requirements. Signal attenuation, impedance matching, frequency planning, shielding, and connection quality all become significantly more critical as frequencies increase.• The Hidden Risk of Small Infrastructure Problems: As networks push into higher-frequency environments, seemingly minor issues—loose connectors, improper torque, poorly terminated lines, or inadequate shielding—can dramatically impact performance. The episode emphasizes that network cleanliness and operational discipline become increasingly important as capacity grows.• Audit Existing Assets Before Expanding Capacity: Before investing heavily in upgrades, operators should evaluate whether current infrastructure is performing as intended. Jayawardene advocates for examining passive and active components, identifying quality issues, cleaning up interconnects, and eliminating unnecessary vulnerabilities before introducing additional complexity.• Reduce Truck Rolls Through Strategic Planning: A recurring operational theme is efficiency. Rather than revisiting the same infrastructure multiple times, operators should coordinate network cleanup, component upgrades, and future-proofing efforts simultaneously—minimizing labor costs while maximizing long-term value.• Lessons From AI and Hyperscale Infrastructure: While service providers and hyperscalers operate at different scales, many of the innovations emerging from AI infrastructure—including advanced optics, power distribution strategies, edge architectures, and high-density fiber deployments—offer valuable lessons for broadband operators looking to modernize their own networks.• Technology Decisions Must Become Business Decisions: Jayawardene explains how his perspective has evolved from evaluating technology based solely on performance to assessing how technology investments drive revenue growth, customer retention, operational efficiency, and long-term asset value. The best upgrades, he argues, are those that pay for themselves while enabling future opportunities.• Customer Loyalty Is the Ultimate Differentiator: Looking ahead three to five years, Jayawardene believes the most successful providers will be those that move beyond competing solely on pricing and bundles. Reliability, seamless experiences, and consistent service quality will become the defining factors that create customer loyalty and sustainable growth.This episode shifts the broadband upgrade conversation from infrastructure replacement to infrastructure optimization. By focusing on targeted investments, operational discipline, and customer-centric decision-making, service providers can create immediate value today while positioning their networks for the demands of tomorrow.
La banda de 6 GHz continúa despertando pasiones y tironeos en la industria de las telecomunicaciones en América Latina. Y es Brasil, una vez más, la que se dispone a estudiar sus implicancias en profundidad. Ahora quiere saber qué opina el sector con el uso de esa banda para WiFi de exteriores, donde también se quiere tener mayores precisiones sobre qué es mejor para el país, si destinar todo ese espectro al uso no licenciado o compartirlo con IMT. Este viernes de podcast, y en nuevo horario, volveremos con el tema porque lo que decida Brasil será brújula para las naciones que dieron marcha atrás o todavía no decidieron qué hacer con esa banda. Te esperamos, como siempre, para que nos acompañes y veamos si entre todos podemos hacer una sugerencia común.

Foundations of Amateur Radio When the Sun burps, something that it does regularly, the mainstream media starts talking about aurorae and optionally the end of the civilised world, not always as clinically as that. What's not talked about, let alone explained, is the nature of the solar burp. You've likely heard the terms Coronal Mass Ejection, or CME, Solar Flare and perhaps Solar Wind, Solar and Geomagnetic Storm, and Solar Flux, but what do these terms actually mean and how do they relate? Let's start with some basic numbers. Our Sun is 150 million kilometres away from Earth. As seen from Earth, the Sun rotates on its axis every 27 days, called a synodic rotation period, because while the Sun is rotating, Earth is moving too. If that wasn't enough, the Sun isn't solid, depending on where you're looking at it, rotation happens at different speeds, faster at the equator, slower at the poles. You might have heard of the Solar Cycle, an 11 year period during which solar activity steadily increases, near the maximum activity its magnetic poles flip from North to South and activity slowly decreases until the cycle starts again. Until quite recently we've deduced this by counting the number of dark areas, called sunspots, on the surface of the Sun. All this to say that our Sun is one massively dynamic environment and with it come a whole lot of processes that science is still discovering. The YouTube channel Astrum has a fascinating video called "We Didn't Predict the Sun Would Do This", that describes much of what we're still learning. We experience the Sun as a source of light, but as a radio amateur you know that light only represents a small set of frequencies in the radio spectrum, it's better to think of the Sun as a radio source, emitting many frequencies at once. The strength of this is measured at 2.8 GHz three times a day at 17:00, 20:00 and 23:00 UTC at the Dominion Radio Astrophysical Observatory in Penticton, British Columbia, Canada. This measurement, the Solar Flux gives a good indication of the level of solar activity. Adjusted for the varying distance between Earth and the Sun, a Solar Flux Index, or SFI, below 70 means that solar activity is very low, above 150 is considered very high activity. In addition to radio waves, the Sun also spits out a continuous wave of particles. Different parts of the Sun emit these at different speeds, varying between 300 and 800 km/s. These particles, the Solar Wind, exist throughout our Solar system. Because the Sun rotates and the particles aren't being emitted evenly we experience the solar wind as having a 27 day cycle. Think of a water filled beach-ball hanging from a rope with a hole in it, spinning, creating spirals of water. Stand in one spot and every time the ball rotates, you get hit by water. When the Sun burps, often at a sunspot, where concentrations of magnetic fields cool the surface, bursts of electromagnetic radiation are generated throughout the radio spectrum. Measured in Watts per square meter, this radiation is called a Solar Flare. Travelling at the speed of light, it takes about nine minutes to arrive at Earth. Sunspot and solar activity is used to model and predict the potential for solar flares. Strength is classified in four stages, class B being the weakest, through C, M, and class X being the strongest, each ten times more powerful than the previous. Within each class, numbers 1 through 9 serve to provide additional resolution, X2 being twice as strong as X1. The most powerful flare on record was estimated to be about X45, recorded on 4 November 2003, when at strength X17 the sensors overloaded. Some solar flares coincide with a massive eruption of particles, some of which are ejected violently, called a Coronal Mass Ejection or CME. A slow CME, travelling at 500 km/s might take three days to hit Earth, an extreme CME, travelling at up to 2,500 km/s might arrive in 16 hours. As the CME particles arrive, they distort Earth's geomagnetic field and depending on the severity, might cause a geomagnetic storm where fields are pushed closer towards Earth causing visual effects as aurorae. Recovery generally takes up to two days, but in extreme cases has been observed to take four. Disturbances of Earth's magnetic field are highly variable and are expressed in several different ways, the K, Kp, A, Ap and G indices. The K-index measured at individual observatories, ranges from 0 to 9 over a three hour period represents the maximum horizontal fluctuation in the geomagnetic field. Values of 5 and above indicating a geomagnetic storm. The planetary Kp-index represents a weighted average of 13 mid-latitude observatories. The National Oceanic and Atmospheric Administration, or NOAA uses a G-scale, between 1 and 5, equivalent to a Kp-index between 5 and 9. The A-index is derived over eight K-index readings over a 24 hour UTC period at a particular observatory, below 20 is calm, between 20 and 50 is unsettled and above 50 is a stormy day. The Ap-index is an averaged planetary index based on data from a set of specific Kp stations. There's more. In 1760, a publication by Swiss polymath Leonard Euler indicated the existence of three stationary points between any two large bodies, known today as L1, L2 and L3. In 1772, Italian born, French mathematician, physicist and astronomer, Joseph-Louis Lagrange, discovered two more stationary points, L4 and L5. Known as the Euler-Lagrange, or Lagrange Points, some of these locations are being used today for solar observations, predictions and early warning systems. Launched on 24 September 2025 and in orbit at L1, between the Sun and Earth, at a distance of 1.5 million kilometres from Earth, the SOLAR-1 satellite acts as an early warning for solar storms. Since particles travel slower than the speed of light, this provides about 15 minutes warning for extreme CME's and longer for slower events. It became fully operational on the 10th of June, 2026. As part of the same Space Situational Awareness Programme as SOLAR-1 is the European Space Agency's Vigil space mission. Intended to be placed at L5, 150 million kilometres from Earth, it will be able to observe solar activity as the Sun rotates towards Earth and reports indicate that this will increase early CME warning by two to four hours. Vigil will also allow for four to five day space weather forecasts. It's planned for launch in 2031, mind you, it's going to take three years to get to L5. Aimed with all that information, I was actually, for the first time, able to at least understand the solar report in my Mastodon feed. "The Sunspot Number has dropped to 88. The Solar Flux Index has risen to 149. G1-class geomagnetic storms are predicted for today. A-Index is 14, K-Index is 2. Chance of flares today: 55% for M-Class, 10% for X-Class." Armed with that information I'm going to make myself a cuppa and figure out what my WSPR beacon has to say about all this. I'm Onno VK6FLAB
Présent dans nos écouteurs, nos montres, nos voitures ou nos objets connectés, le Bluetooth est devenu indispensable sans que l'on y pense vraiment. Derrière cette technologie discrète se cache pourtant une histoire étonnante, des choix techniques ingénieux et des évolutions qui préparent déjà les usages de demain.* Épisode soutenu par Frogans : https://www.f2r2.frAux origines du BluetoothNé au début des années 1990 dans les laboratoires d'Ericsson, le Bluetooth avait un objectif simple : remplacer les câbles reliant les appareils électroniques. Développée notamment par l'ingénieur néerlandais Jaap Haartsen, cette technologie devient rapidement un standard grâce à la création du Bluetooth Special Interest Group (SIG) réunissant Ericsson, IBM, Intel, Nokia et Toshiba.Son nom rend hommage au roi danois Harald Bluetooth, célèbre pour avoir unifié les peuples scandinaves. Une métaphore parfaite pour une technologie destinée à faire communiquer des appareils de marques différentes.Comment fonctionne le Bluetooth ?Le Bluetooth utilise les ondes radio de la bande des 2,4 GHz, la même que le Wi-Fi. Pour éviter les interférences, il change de fréquence jusqu'à 1 600 fois par seconde grâce à une technique appelée « saut de fréquence ».Avant toute communication, les appareils effectuent un appairage, qui permet de créer des clés de chiffrement et d'établir une connexion sécurisée. Une fois cette étape réalisée, ils se reconnaissent automatiquement lors des connexions suivantes.Pourquoi le Bluetooth a changé nos habitudesD'abord conçu pour les conversations téléphoniques, le Bluetooth est progressivement devenu la norme pour diffuser de la musique, connecter une souris, un clavier, une montre connectée ou encore une manette de jeu.L'arrivée des écouteurs True Wireless a marqué une nouvelle étape grâce à une synchronisation très précise entre les deux écouteurs, ouvrant la voie au succès mondial des appareils totalement sans fil.Une technologie fiable… mais pas parfaiteComme toute technologie sans fil, le Bluetooth peut être la cible de cyberattaques. Les risques restent limités à condition de maintenir ses appareils à jour et d'éviter d'accepter des demandes d'appairage provenant d'équipements inconnus.Autre limite : toutes les fonctionnalités ne sont pas présentes sur tous les appareils, même lorsqu'ils affichent la même version de Bluetooth. Chaque fabricant choisit les fonctions qu'il implémente.Les évolutions qui préparent l'avenirLe Bluetooth continue d'évoluer avec le Bluetooth Low Energy (BLE), conçu pour les objets connectés à très faible consommation, puis avec LE Audio, qui améliore la diffusion sonore.Les versions les plus récentes introduisent également des fonctions comme Auracast, permettant de diffuser un même flux audio vers plusieurs appareils, ou encore le Channel Sounding, intégré au Bluetooth 6, capable d'estimer précisément la distance entre deux appareils afin de renforcer la sécurité de certains usages, comme les serrures connectées.Le Bluetooth est ainsi devenu bien plus qu'un simple remplaçant des câbles : une véritable infrastructure invisible qui relie aujourd'hui des milliards d'objets dans notre quotidien.Hébergé par Audiomeans.

Foundations of Amateur Radio The other day a friend of mine mentioned in passing that they'd hooked their Home Assistant dashboard to an RTL-SDR dongle to listen to the various ISM bands. If that sounds like gibberish, let me elaborate. "Home Assistant" is a tool that, among other things, allows you to control devices throughout your house, think lights, vacuum cleaner, air conditioning, and power sockets. It turns out that there are various plug-ins that allow you to connect it to a tool called "rtl_433", more on that in a moment. ISM, or Industrial Scientific and Medical, is a global collection of 13 radio bands, regulated by the ITU, the International Telecommunications Union, where devices are permitted to transmit all different types of signals, think microwave ovens, NFC, or Near Field Communications, Wi-Fi, Bluetooth, but also weather stations, security devices, battery monitors, tyre pressure monitors, remote keyless entry, garage door openers and plenty more. The most "well known" ISM band is 433 MHz, but the most used ones are those we think of as Wi-Fi bands, 2.4 and 5.8 GHz. It sometimes comes as a surprise that Bluetooth and Wi-Fi share the same frequencies with each other and many different bits of technology. While I'm here, I'll also point out that there are ISM allocations within the HF bands and up to 245 GHz, so plenty of spectrum to explore. A different friend heard about my challenges with two remote controls, came by for a coffee and dropped off a frequency counter and left me to determine what type of remotes I had in my hands, since labelling was absent. After charging this sparkly new gadget I spent a while trying to make it do the needful, but ultimately, despite trying in multiple locations without local interference was unsuccessful, this likely caused by the nincompoop behind the controls, but I digress. It occurred to me that an RTL-SDR dongle is perfectly suited to the job, as long as I can scan through the various frequencies and discover just which ones were associated with my cantankerous remotes. As is my want, I got distracted by installing "rtl_433". I have to tell you, just plugging in an antenna into an RTL-SDR dongle, I'm currently using my 2m and 70cm dual band antenna, running the tool and looking at the log, in the last half hour alone, I've seen 372 reports, across 16 devices, including several cars and a truck, weather stations, security devices and plenty more; half an hour later we're up to 22 devices and 771 reports, and 24 hours in we're up to 128 devices, nearing 17,000 reports. I'll note that this is using an RTL-SDR dongle, no fancy radio, no filtering, no interference rejection, all straight from the device. As you might expect, the reports keep trickling in, every 15 seconds or so there's a new decode and at this point I'm pretty sure I don't need to invest in a weather station in the near future, and if I figure out which Hyundai is driving around with low tyre pressure, I'll let them know. Also, because I'm not just lollygagging, my remotes don't appear to emit anything that rtl_433 can decode, but I did notice that the reports stopped coming in while the remote was active, so I suppose that's progress. In-case you're wondering, within "Fifty Things you can do with a Software Defined Radio", this is number "11: Read your neighbors'[sic] sensors". At this point I hear the calls from the peanut gallery: "But .. but .. but, this isn't amateur radio" .. to which I say, "Really?" In other words, amateur radio is what you make it and right now I'm interested in figuring out why my remotes are acting up and what better way than to play with radio, at whatever frequency takes my fancy. I wonder if there's any HF gadgets I can monitor. I'm Onno VK6FLAB

This guide explains the complete pairing process using the Energizer Connect app, including entering pairing mode, adding the device, configuring bulb count, and accessing basic controls.RequirementsEnergizer Connect Patio String LightsEnergizer Connect appWi‑Fi network (2.4 GHz)Power outletStep 1: Power the Lights OnThe lights are plugged in and initially illuminate white. After a moment, the bulbs begin blinking red. The blinking red state indicates that the lights have entered pairing mode and are ready to be added to the app.Step 2: Begin the Pairing Process in the AppThe plus button is selected within the Energizer Connect app. The option to add a device is chosen. If the app automatically detects the lights, the process may skip ahead. When performing a manual setup, the lighting category is selected to continue.Step 3: Connect to Wi‑FiThe app displays instructions for resetting the device if it is not already blinking red. Because the lights are already in pairing mode, the process continues directly to Wi‑Fi configuration. The app connects to the lights and begins the pairing sequence.Step 4: Wait for the Device to SyncDuring the connection process, the bulbs turn solid white. This indicates that the lights and the app have communicated successfully. The app continues processing until the device is added.Step 5: Name and Assign the DeviceA name is entered for the lights. In the example shown, the lights are named "Beastro." The location is set to "Outside," and the setup is completed by selecting Finish. The app updates the device information and moves to configuration.Step 6: Set the Bulb CountThe app requests the number of bulbs in the string. Each string contains 12 bulbs, and up to 120 bulbs can be connected in a single linear run. The correct number is entered to ensure animations match the physical layout. The configuration is confirmed.Step 7: Explore Basic ControlsThe app displays the full bulb layout. The lights can be turned on or off, and colors can be selected using the color wheel. Saturation levels can be adjusted, and individual bulbs can be configured if needed. A simplified color picker is also available.Step 8: Review Scenes and Additional FeaturesPredefined animated scenes are available, including options such as "Lotus Flower." Music‑responsive modes can be enabled. A countdown timer allows the lights to turn off automatically at a chosen time.Step 9: Confirm Wi‑Fi CompatibilityAlthough many modern Energizer Connect products support both 2.4 GHz and 5 GHz networks, this model uses 2.4 GHz exclusively.Completion OutcomeThe lights are paired, configured, and ready for use. The app provides full control over color, animation, and scheduling.
Make a Logo on Fiverr The Aosu T2 Pro is not your typical wireless security camera. In fact, the big idea here is that you might not want to put it directly on your house at all. Instead, this dual-camera, solar-powered system may be more useful when placed away from the building, looking back at your doors, windows, driveway, or storefront. That gives the Aosu T2 Pro a different kind of home security advantage. Rather than only watching outward from the wall, it can give you a wider view of what is happening around the property — especially if someone walks up to check doors, windows, or entry points. A Dual-Camera Security Setup The Aosu T2 Pro uses a two-camera design. One camera gives you a wide 170-degree static view, while the second camera can pan and tilt to follow movement. That combination makes it more flexible than a basic fixed-position wireless security camera. The system captures dual 3K images and includes night vision, so it can keep watch during the day or after dark. There is also an 8x hybrid zoom, although it is digital zoom. That means you probably do not want to place the camera too far from the house or business you are trying to monitor. Solar Power Makes Placement More Flexible One of the biggest selling points of the Aosu T2 Pro is the solar setup. The camera has a 9,200 mAh battery inside, and the included solar panel helps keep it charged without needing a constant power cable. That opens up a lot of placement options. You can mount the camera on a pole, fence, garage, shed, or another location facing the house. The solar panel can attach directly to the camera or be placed separately in a better sunlit area. That is especially useful in colder states or areas where sunlight changes throughout the year. If the camera is mounted under a gutter or in partial shade, being able to move the solar panel can make a big difference. Setup and App Controls The Aosu T2 Pro connects through the Aosu app on iOS or Android. Setup includes scanning the QR code or connecting through Bluetooth when the camera is nearby. The camera connects to 2.4 GHz Wi-Fi, which works for range but may disappoint users who prefer 5 GHz support. Inside the app, you can control the PTZ camera, adjust surveillance settings, set notification preferences, turn AI tracking on or off, and choose detection options for people, vehicles, or pets. You can also control night vision modes, speaker volume, privacy settings, battery management, LED status lights, and smart home connections. The camera also supports Amazon and Google smart home ecosystems. Local Storage or Cloud Options The Aosu T2 Pro supports a microSD card up to 256 GB, which gives users a local storage option instead of relying completely on cloud storage. Subscription options are also available for users who want additional cloud-based features. One important note: files stored on the microSD card are not simple MP4 files that someone can pull out and immediately watch. They need to be accessed through the camera and app, which adds some protection if the card is removed. Security and Privacy Notes Aosu is a global security brand founded in 2021, focused on smart AI tracking equipment. The company uses its own software and provides in-house support. The app is Chinese-based, while cloud data is held in the United States on AWS servers. For a connected home security device, that matters. A security camera is not just another gadget. It handles video from your property, so app security, data handling, and company support are important parts of the buying decision. Real-World Use: House or Business In testing, the Aosu T2 Pro worked well when positioned away from the building and aimed back at the front. At around 20 feet from the building, it captured a strong amount of detail from both the wide camera and the PTZ camera. That makes it useful not only for a house, but also for a small business or community building. It can watch the front entrance, capture vehicles passing by, and record people approaching doors after hours. Night Vision Performance The camera performs well in low light. It includes black-and-white night vision, color night vision, and lighting options that can illuminate the area when motion is detected. In a dark room test, the camera still produced usable video. The illumination feature is also helpful when you need more detail or want the camera to act as a visible deterrent. Pros and Cons The biggest advantage of the Aosu T2 Pro is flexibility. The dual-camera system gives you both a wide fixed view and a PTZ tracking camera. The solar panel can be detached and positioned for better sunlight. The app gives you a lot of control over detection, notifications, lights, audio, and tracking. The video quality is also strong, especially for a wireless security camera. Dual 3K capture, night vision, AI tracking, and local storage make this a serious option for home security or small business monitoring. The articulating arm is useful, but if the camera is mounted low enough for someone to reach, they could physically turn it away. That could create a blind spot, especially for the fixed 170-degree camera. The power button, reset button, and microSD card slot are also located on the camera body. If the camera is mounted too low, someone could potentially turn it off or tamper with the card. The biggest software limitation is the lack of a desktop web app. If you want to view or download clips from a PC or Mac, you are basically stuck using the mobile app or an Android emulator like BlueStacks. A browser-based dashboard would make this feel more like a traditional security system, especially for users with multiple cameras. Final Thoughts The Aosu T2 Pro is a smart, flexible wireless security camera that works best when you think beyond the obvious mounting spot. Instead of putting it directly on the house, consider placing it where it can watch the house. That is where the dual-camera design makes the most sense. The wide-angle camera can cover the full scene, while the PTZ camera can follow movement and give you a closer look at what is happening. It is not perfect. The physical tampering concerns and lack of a web dashboard are real drawbacks. But with solar charging, dual 3K video, AI tracking, night vision, two-way communication, and local microSD storage, the Aosu T2 Pro is a strong option for anyone looking to add flexible home security without running power cables.

Antenna arrays are used everywhere to enhance the wireless signal quality through beamforming and aperture gains. A common practice is to arrange antennas uniformly along a line or in a rectangle, but this is not necessarily the preferred arrangement. In this episode, Emil Björnson and Erik G. Larsson discuss how the geometry of an antenna array affects the shape of the beams it can transmit and the ability to spatially multiplex many users. They uncover how uniform arrays excel at packing many antennas into a compact space, while adjacent antennas collect redundant information about the world around us. In future systems operating above 6 GHz, we might not be able to afford to fill the aperture with antennas and can instead place them in a sparse non-uniform pattern. The vision is to optimize the arrangement at each base station site to maximize its communication and/or sensing performance. The conversation covers grating lobes, minimum redundancy arrays, preoptimized irregular arrays, and movable/fluid antenna systems.

What makes a UFO hotspot? In Episode 147, we investigate the strange case of Rocky Mountain Ranch in Colorado. We also discusss Andrew Bustamante. A former CIA officer and star of Beyond Skinwalker Ranch, Bustamante brings his technical surveillance expertise to a location that has drawn comparisons to the infamous Skinwalker Ranch for decades. From "maddening hums" and energy spikes at the 1.6 GHz frequency to a terrifying 1970s encounter involving a disembodied voice that warned a family to "remain silent," we break down the evidence. We also explore how Bustamante's CIA background (detailed in his memoir Shadow Cell) shapes his approach to the unknown and why some researchers are taking this "other hotspot" more seriously than ever. Based on the provided sources, the phenomenon at Rocky Mountain Ranch in Colorado shares several striking similarities with Skinwalker Ranch, to the point that researchers consider it a major "hot spot" for related anomalous activities. Here is how the phenomena at the two ranches compare: Shared Frequencies and Energy Spikes One of the most significant connections between the two locations is the 1.6 gigahertz frequency, which is strongly correlated with "high strangeness" at Skinwalker Ranch. When investigators from the TV show Beyond Skinwalker Ranch broadcast a voice over this exact frequency at Rocky Mountain Ranch, they observed a "massive reaction" and "tons of energy" bouncing around the house, suggesting the phenomenon at both locations may interact with or be triggered by the same radio frequency. Types of Anomalous Phenomena While both ranches feature high strangeness, the specific events reported at Rocky Mountain Ranch include: Hums and Bangs: Similar to the strange noises at Skinwalker, residents and investigators at Rocky Mountain Ranch have reported hearing loud, maddening hums and underground bangs. Lights and Voices: During the 1970s, childhood resident Katie Paige experienced the power going out, a blinding light shining through the window, and a terrifying electronic voice emanating from the house itself, telling the family, "we have allowed you to remain... your friends will be instructed to remain silent". Voices were also reportedly heard coming through stereo equipment that was turned off. The Feeling of Being Watched: Experiencers at Rocky Mountain Ranch have reported a heavy, uneasy feeling of being watched, a psychological element frequently reported by investigators at Skinwalker Ranch. Documentation and Investigation Because of these similarities, Rocky Mountain Ranch was actually featured in the book "Hunt for the Skinwalker" under a section dedicated to "other hot spots," though the family and location were kept anonymous at the time. The strange events at Rocky Mountain Ranch were also officially documented in the late 1970s by the Aerial Phenomenon Research Organization (APRO), a precursor to MUFON. https://rockymountainufo.com/
Apple lo ha vuelto a hacer. Pero esta vez no ha sido un "más de lo mismo con mejor nota". El 3 de marzo de 2026 presentó los chips M5 Pro y M5 Max integrados en los nuevos MacBook Pro, y lo que hay dentro es el cambio de arquitectura más importante desde que llegó el M1. No hablamos de más núcleos ni de un proceso de fabricación más fino. Hablamos de repensar desde cero cómo se construye un chip. En este episodio desmontamos la Fusion Architecture pieza a pieza: qué es un die, por qué dividirlo en dos cambia las reglas del juego, qué implica para la disipación térmica, para la fabricación y para el futuro de Apple Silicon. Hablamos de los Neural Accelerators integrados en cada núcleo GPU, del aumento del ancho de banda del Neural Engine, de los 614 GB/s de memoria del M5 Max y de por qué eso importa más que los GHz cuando hablamos de inteligencia artificial en local. Y hacemos la comparativa con NVIDIA que todo el mundo hace pero casi nadie hace bien: CUDA vs MLX, H100 vs M5 Max, datacenter vs mochila. Sin banderas. Con números reales.
