Hi Barry,Concerning the separate GR-ham mailing-list, I don't know if it really needs to be a "GR ham-radio" list, but what I think would be useful is a separate mailing-list to discuss signal-processing (that happen to use GNU Radio), separate of the 'discuss-gnuradio' list that is more related to questions on GNU Radio itself.
I am also still learning SDR, and I have a number of question on how to decode signals (e.g. "I want to decode RTTY with 1.5 stop-bits, what's the best way to handle that half a bit at the end without impacting the clock-recovery block?") here I have been hesitant to post here in the GR list as it's more about signal-process then about GNU Radio. When talking to fellow hams who tried GNU Radio, a lot of them have the same problem: how to create a working flowgraph? What blocks to use? What do all the parameters of that block really do and what do I value should I put in there?
So, yes, a separate list would be nice. .. but I don't know if a "GR Ham Radio" is the best combination.
- Why only Ham radio?SDR and GNU Radio seams to me one of the best tools to promotion amateur-radio, especially if you target people from the open-source / hackerspace / maker scene. Focussing to much on amateur-radio will -I think- might mean you lose this opportunity.
- For the amateur-radio community, focussing to much on GNU Radio might not be ideal neither. For me, the main topic here is SDR, signal-processing, DSP and data-communication, ... GNU Radio is only part (be it, a very big and important part) of that. Most hams start out with a simple RTL-SDR dongle and just *use* it for some project: APRS receiver, beacon receiver, to track HABs to listen to weather-satellites, listen to QO100, ... It's usually only in a later stage that they move to GNU Radio, when they are comfortable with using SDR and are interesting going the next step: learn how SDR works internally and develop SDR applications themselves.

Thank you for your feedback! It looks like we have a viable idea. Here are some additional items to consider: ** use BigBlueButton or Zoom ** have a host / moderator present a topic with a demonstration ** limit to one hour (especially if using BigBlueButton) ** a time on the weekend might be better - something like 20:00 UTC?** I will put out a news entry on the gnuradio.org homepage as soon as a kickoff seems feasible. Marcus will help "as much as he can"** possibly start a GR Ham Radio mailing list like discuss-gnuradio Thank you for your continued interest and ideas. 73 and stay safe, --- Barry Duggan KV4FV https://github.com/duggabe On Mon, 21 Sep 2020 11:13:29 +0200, Marcus Müller wrote: Hello Barry, hi everyone, I just wanted to say I was very impressed with all the activity in the breakout session, and how productive everything was. I'd find it super interesting if aside from the social benefit of ragchewing (no matter whether that happens on a video conference, via pure voice comms, or in a text chat), people had would also take the chance to give a short "impulse" presentation on what they think would be interesting for the rest; for example, I think Barry's digital modulations tutorials would be extremely interesting for a lot of people. But also, a bit on stuff like (brainstorming here) "how to make use of the new digital predistortion module to get the most out of my system", "I've invented a digital mode, and you'll never guess what happened next", "how it took me a month to figure out why I wasn't seeing any satellites and why I hate storks", "SDR in club education settings", …. Nothing that takes 2 hours, but something to get discussion off the ground, and then if discussion shows people like where things are going, go deeper into it. Cheers, Marcus
