About the YouTube Edition
So much good stuff… on YouTube! I’m now subscribed to… a number of… Zero Retries Interesting YouTube channels. With that, YouTube’s recommendation algorithms have homed in on my preferences for viewing Zero Retries Interesting content such as “Data / Packet Radio via DMR”, that I wouldn’t have otherwise known about. One downside to this is that if I view a YouTube video on a channel that I’m not subscribed to (such as “andy kirby”, then I never see that video again, so I have to capture it immediately. Having captured it, best to share it via Zero Retries.
These ten eleven videos and YouTube channels below are representative of what I watch on YouTube when I have some downtime and I can passively consume content. If this “YouTube Edition” works, it may become a regular addition to the growing Zero Retries “media family”.

HB9BLA Wireless
The HB9BLA Wireless YouTube channel by Andreas Spiess HB9BLA is one of four that I consider consistently Zero Retries Interesting to promote in every issue of Zero Retries. HB9BLA doesn’t post often (months can go by) but when he does, it’s worth watching. The video below is what drew my attention to this channel.
KM6LYW Radio
The KM6LYW Radio YouTube channel by Craig Lamparter KM6LY is one of four that I consider consistently Zero Retries Interesting to promote in every issue of Zero Retries. KM6LYW created the DigiPi project which has developed a considerable user base. I really enjoy his matter-of-fact presentation of data modes. The video below discusses SDR++ which is a new cross platform Software Defined Radio software.
ModernHam
The ModernHam YouTube channel by Billy Penley KN4MKB is one of four that I consider consistently Zero Retries Interesting to promote in every issue of Zero Retries. Not only is his content consistently technical (and good) but he’s dead center of the demographic of a young techie is (who I consider) the future (if there is to be a future) of Amateur Radio. The video below is a fantastic explanation of the mindset of a talented, well-spoken, millennial with a technical background. I will refer to this video frequently.
Tech Minds
The Tech Minds YouTube channel by Matthew Miller M0DQW is one of four that I consider consistently Zero Retries Interesting to promote in every issue of Zero Retries. I really appreciate the prospective of a European techie Amateur Radio Operator. I’ll confess that I still suffer from “QO-100 Envy” and thus I especially enjoy the videos related to QO-100 operation, like the one below.
Ham Radio Crash Course
I haven’t quite “promoted” Ham Radio Crash Course (HRCC) by Josh Nash KI6NAZ into consistent recommendation in Zero Retries… but it’s close. KI6NAZ is a hardcore techie, but HRCC’s content is mostly for mainstream Amateur Radio rather than Zero Retries Interesting content. That said, below is just one recent HRCC video that is Zero Retries Interesting. (Two others are purchasing a Ford F-150 Lightning electric vehicle and using a Steam Deck handheld computer for Amateur Radio).

…
Update - KI6NAZ received one of the first (that I’ve seen) opportunities to do a no-interference-from-Icom, take-your-time, say-what-you-will review of the so-new-it’s-not-yet-shipping Icom IC-905 VHF / UHF Microwave radio. Of course, that’s very Zero Retries Interesting, so I had to include it here. My thanks to Ren Roderick K7JB for the pointer to this video.
Data / Packet Radio via DMR
It’s frustrated me that the specification for Digital Mobile Radio (DMR) includes the capability for data exchange (and that DMR, by fundamental definition, is data communications), but data interoperability between various manufacturer’s implementations of DMR has not been established. Thus “Data Over DMR” has been a nebulous concept in Amateur Radio (per my research to date) except for (10 key keypad) unit to unit text messaging and some position data transmissions (“APRS” over DMR). Note that the data being exchanged in this video are between two units of the same manufacturer (Motorola). I did some very brief (incomplete) research on the radios mentioned in this video, and they are expensive (intended for professional use). Despite that dis-recommendation for consideration for Amateur Radio use, it’s good to see at least a reference demonstration that data communications are possible with DMR radios.

Masters Communications Amateur Radio Digital Radio Devices - 03/16/2023
Kevin Custer W3KKC and Scott Currie NS7C are two subject matter experts (Obi Wans to those of you in the Star Wars generations) on data modes in Amateur Radio. Both W3KKC and NS7C are especially expert on using audio interfaces (variously called “USB sound cards”, TNCs, etc.) with Amateur Radio radios, especially those that have accessory connections for higher speed data modes such as VARA FM and 9600 bps packet radio.

The Wide World of Open Radio Levi C. Maaia, Ham Radio
This is an interview with Levi Maaia K6LCM by Doc Searls (a long-lapsed Amateur Radio Operator) and Shawn Powers on FLOSS Weekly (Free Libre Open Source Software) I was previously interviewed on this program. K6LCM discusses a lot of innovative Amateur Radio activity occurring in the Santa Barbara, California area.

Attempting To Build Antenna Array From Old Satellite Dishes
You’ve heard of the Very Large Array (of radio telescopes)? The on screen subtitle of this video aptly describes this project as the Very Small Array. As I watch this channel, it feels reminiscent of a British television series called Scrapheap Challenge - can I take this pile of X and accomplish Y? This is another YouTube channel that occasionally features Zero Retries Interesting content such as this and another video mentioned in Zero Retries 0088.

Amateur Radio Space technology… can’t get enough! This video is representative of the (quite a bit of) Zero Retries Interesting content presented as part of the semi-annual QSO Today Virtual Ham Expo. Not all videos from the Ham Expo events are on YouTube - see QSO Today Virtual Ham Expo Presentations - All Previous Expos.

Closing the Channel
In its mission to highlight technological innovation in Amateur Radio, promote Amateur Radio to techies as a literal license to experiment with wireless technology, and make Amateur Radio more relevant to society in the 2020s and beyond, Zero Retries is published via email and web, and is available to anyone at no cost. Zero Retries is proud not to participate in the Amateur Radio Publishing Industrial Complex, which hides Amateur Radio content behind paywalls.
