Digital Modes with Virgil (K4CUP).

This topic came from a comment on one of my previous videos. Do we have too many digital modes? Should be combine them all or get rid of several and set a "standard"?

I picked up the DigiRig DR-891 sound interface, which is specifically made for the Yaesu FT-891 radio. The FT-891 doesn't have its own built-in sound card, so this interface is a great step towards making the FT-891 plug-n-play. Let's take a look at how to set this up and how simple it is to make FT8 contacts from POTA with this DigiRig.Today's video is sponsored by Ham Radio Prep - save 20% off of all course with code jason20Links to items in video:DigiRig DR-891 - https://digirig.net/product/digirig-dr-891/p/1/Yaesu FT-891 - https://amzn.to/3ASD8NVReel POTAable Antenna - https://reelefhw.com/Panasonic FZ-G1 Toughpad - https://amzn.to/4cF3lwVBecome a supporter of this podcast: https://www.spreaker.com/podcast/ham-radio-2-0--2042782/support.

Won't be long before my tower is complete

Let's make HF digital modes great again. Try something new, that is more personal between hams. Have a conversation, enjoy the hobby.

In this episode Rod VA3ON and Mike VA3MW host Michael Black who talks about how to set up your station's audio for success using digital modes.

Answering a question about tech operators and the bands and modes they can use for digital.

I originally recorded this for a video to put on my YouTube channel but the video quality wasn't the best with the camera on my laptop and my motions as i talk, jumping around like Gordon Ramsay, I figured people would not watch it. But it may be suitable for a listen to and from work if you got nothing to listen to.

Ham radio has more than just FT-8 for digital operation. Listen to this episode to hear about more modes that you may have never heard of..

On this episode, we talk about digital modes. If you're "digital curious", this one is for you. We also meet the military hero that leads the 100 Watts and a Wire Digital Team.

Foundations of Amateur Radio Previously I've explained how Radio-teletype or RTTY works from a technical perspective. If you recall, it uses a technique called Frequency Shift Keying, or FSK to encode digital information. It does this by transmitting a carrier across two alternating frequencies, allocating one as a SPACE and the other as a MARK, or as a binary 0 and a binary 1. There are several other ways of encoding information and today I'm going to look at Phase Shift Keying, or PSK, which I find humorous, because Phase is spelled with a P, but it sounds like an F, which links the FSK and PSK together, but then I've always had a strange sense of humour. Imagine if you will a sine wave. It's the one you learned in high-school, nothing sophisticated about it, just keeps going up and down over time. Now imagine another one. Also going up and down over time. If these two sine waves are synchronised, going up and down at the same time, the difference between them is 0. If one of the sine waves is going up, while the other is going down, then the difference between them is 1. That is enough to give you a binary 0 and a binary 1. One of the sine waves is a carrier, so it's transmitted continuously, and the other is changed depending on whether you're sending a 0 or a 1. These two sine waves are said to be "in-phase" when they're both going up and down at the same time, and "out of phase" when they're going in opposite directions. This is how Phase Shift Keying works. And the simple example I gave is known as BPSK, or Binary Phase-Shift Keying. There are countless variations on this. For example, you don't need to have them going in completely 180 degrees opposite directions, you could go only 90 degrees, or even 45 degrees, which would allow you to encode more information across a shorter time span at the cost of less accurate decoding at the other end. You could play with the carrier and instead have the signal be compared to itself, making it more robust in some circumstances, or you could have multiple of these signals happening at the same time. You could change the amplitude of the carrier and allocate specific byte values to each combination. For example, one variation, an encoding method called "16-QAM" allows you to create 16 different signals, which equates to sending 4 bits at a time. Each of these have different advantages and disadvantages, trade-offs between speed, reliability, error detection, impact of polarisation changes in the ionosphere, energy efficiency, etc. You might be surprised to learn that these techniques are not only used inside Amateur Radio and PSK31, they're also used in Wi-Fi, Bluetooth, Ethernet, RFID and countless other places, like remote controls, hard-drives, tape recorders, satellite communications, mobile telephony, etc. If you get hooked, there's lots of maths that you can associate with all of this - if that floats your boat, but you don't need any maths to grasp how it works. Phase Shift Keying, one of the many Digital Modes that make our world go round. I'm Onno VK6FLAB

Foundations of Amateur Radio The continued discussion in our community about Digital Modes got me thinking about what a Digital Mode actually is. At the most fundamental level, it's about encoding information into discrete chunks to exchange information. Morse Code is an example of a Digital Mode, made up from combinations of dits and dahs. If you change frequency whilst sending dits and dah's you invented RTTY or Radio-teletype. There are two frequencies involved, 170 Hz apart, where the lower frequency is the SPACE frequency and the upper frequency is the MARK frequency. If someone gives you a RTTY frequency, they're talking about the upper frequency. Instead of using Morse Code to send messages, RTTY uses 32 different codes, 5 bits, to exchange information. This isn't enough for the entire alphabet, with digits and punctuation, so two of the codes are used to swap between Letters and Numbers. Some radios can change frequency between the lower SPACE and upper MARK frequencies in a single transmission. This way of transmitting is called FSK, or Frequency Shift Keying. It's a lot like moving the VFO around whilst keying a Morse-key. Not something you'd do manually, since in Amateur Radio, this is generally happening 45 times a second. If your radio can't do the frequency shifting, then another way is to use Audio Frequency Shift Keying of AFSK, where instead of changing the frequency, you change an audio tone by 170 Hz. Without getting technical about how this works, if you've ever listened to Morse Code with a radio, you'll have noticed that as you change frequency, the sound changes. If you were to change the frequency of your radio by 170 Hz, the sound would also change by 170 Hz. So with that in mind, if you were to change the sound by 170 Hz, the receiver wouldn't care if you were changing the transmit frequency or the audio frequency, since it both sounds identical at the other end. Most of the time a computer is generating two tones, a tone for the SPACE, or lower frequency and a tone for the MARK or the upper frequency. It comes out of the speaker of the computer, which you feed into the microphone of the radio and your radio then generates a normal SSB signal that is experienced by the listener at the other end as a Radio-teletype. Pretty nifty and if you understand this, then most of the other Digital Modes in use today use similar methods. I'm Onno VK6FLAB

Foundations of Amateur Radio Having a Digital Mode in your shack appears to be a special privilege, at least in some parts of the world. If you'd like to learn all there is to do with using a Digital Mode you need to pay attention and I'll share the secret, it won't take long. If you want to distinguish yourself as a Digital Mode Diva, you need to know that Morse, RTTY, FSK and PSK are digital modes and you must also remember that the bandwidth of a data transmission is dependent on speed and mode. At this point you've covered all the syllabus requirements for holding a Standard License in Australia in relation to operating a Digital Mode. If you want to climb the Mountain of Digital Mode Magic, you need to remember two acronyms, FEC or Forward Error Correction and ARQ or Automatic Repeat Request. You also need to remember four numbers, 31 Hz for PSK31, 250 Hz for RTTY, 730 Hz for Packet Radio and 300 Hz for FSK. And if you want to get really fancy, I should point out that there are several versions of each of these modes and different ways to implement them, so those numbers will change depending on who's teaching you. If I go on to tell you that a Terminal Node Controller or TNC is a black box with two audio leads, one for the microphone and one for the speaker and that you plug those into the appropriate sockets on your radio, you know all that is required to hold an Advanced Certificate in Australia for using a Digital Mode. If you don't want to blow up your radio, then you should also remember that there is a thing called Duty Cycle that will come to haunt you if you get it wrong. That's it, now you know everything there is to know about using Digital Modes. Actually, I'm lying. When you say the letter A on air you use the word Alpha. You're sending extra information so the other end has a better chance of understanding what you said. That's Forward Error Correction. And when you say the same thing repeatedly, like saying CQ, CQ, CQ, if you don't get an acknowledgement from the other end, that's Automatic Repeat Request. Now you really do know all there is to know about Digital Modes according to the syllabus for both Standard and Advanced Licenses in Australia. I'm Onno VK6FLAB

Foundations of Amateur Radio Over the past six years or so I've single mindedly been producing a weekly segment about Amateur Radio. Over time this has evolved into a podcast which gets about half a million hits a year. Naturally I receive emails and I do my best to respond in a timely fashion. One of the other things I do is announce a new edition of the podcast on several different sites where listeners have the opportunity to share their views about what ever is on their mind. Sometimes their response is even about the podcast itself, though I confess that some comments appear to indicate that listening isn't part of a requirement to actually form an opinion about what it is that I have said that week. All that aside, I find it immensely fascinating that the responses I receive vary so much in perspective. It's not hard to understand and observe that our community comes from people along all walks of life. From nine-year olds to ninety-year olds and everything in between. I tend not to comment directly on such feedback, since everyone has their own opinion, but I came across one post recently that made me sad about the spirit of some Amateurs. In a seemingly bygone era there was a sense that Amateurs would help new people join the community and help them find their way into this vast range of discovery. A place where no question was wrong, where shared experiences are cherished and where the lack of knowledge was an opportunity for learning. It seems that the moniker that we carry, that of HAM, supposedly because when compared to Professional Telegraphers, we were considered HAM-fisted, went on to form the basis of a proud tradition of experimentation and renewal. Across the globe we see a refresh of the license conditions on a regular basis. We saw that here in Australia with the introduction of the so-called Z-call and K-call, looked down upon by Real Amateurs who had a much more stringent licensing regime. We discontinued Morse Code as a requirement for an Amateur License as part of a global treaty agreement in 2003. In Australia this meant that from the 1st of January 2004, Morse Code was no longer required if you wanted to obtain an Amateur License. As you know, that didn't signal the end of Morse, just that it wasn't legally required any more. I'm one of many Amateurs learning Morse because I want to, not because I have to. I'd also point out that it was discontinued by global agreement, not two random guys in Canberra. Back to my point about the spirit of this hobby. The point that was being made is that the Foundation Class license isn't a real license and that it is just being handed to anyone who asks, not like their requirements for Morse Code and a written exam, rather than a multiple-choice test. Essentially conveying that my undignified license and that of my fellow Foundation Licensees isn't to be confused with the noble one that a Real Amateur holds. This kind of response saddens me and frankly I hear it too often. It's as-if we as a community still have not learned that the world moves on. Technology, in many ways the basis of Amateur Radio, evolves. For example, in the current requirements for an Amateur License there is a long-winded discussion about the impacts of spurious transmissions on Analogue Television. In Australia, the last Analogue TV broadcast happened on the 4th of December 2013, that's years ago, but it's still required reading on the Amateur License Syllabus. Similarly we learn about Valves, but attempting to actually obtain such a device is nigh-on impossible. Should we still be learning about those aspects of Electronics, or should we move on? Amateurs are an inventive lot, we make up new modes, link up new technologies, experiment with all manner of stuff and sometimes we end up with something new, like IRLP, AllStar, SDR, Digital Modes and the like. All because someone got curious, couldn't help themselves and started to fiddle. As things fall off the radar at one end, Analogue TV, Morse Code, Valves, the other end picks up things, JT65, Digital TV, Lithium Polymer Batteries and whatever else comes around the corner. So, I'm sad that there are people who feel that my license isn't a real one. As many of my peers, I have a piece of paper from my regulator that begs to differ and a community of enthusiastic eager people who are attempting to find their home among our hobby as it evolves into the future. Last week I talked about the death of our hobby and that it was vastly mis-represented. As I said, year-on-year, more and more Amateurs join, but overall the numbers decline. I think that opinions expressed about the lack of real licensing, decrying the death of Morse etc. is a symptom of why it is that we have a retention problem in our hobby. Everyone is entitled to an opinion, but that doesn't mean I have to agree. This is my hobby too and disdain is my fuel! I'm Onno VK6FLAB
