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. 73 kristoff - ON1ARF On 22/09/2020 14:30, Barry Duggan wrote: > Thank you for your feedback!
