I was about to order another RPi to build a Sgate for APRS which would have needed yet another QFH antenna. I already have a working ground-station for receiving VHF satellites so why duplicate the hardware?
Has anyone successfully modified a SatNOGS ground station to do double duty by also acting as a APRS Satgate by decoding and sending APRS packets to aunz.aprs2.net via direwolf.
I read somewhere that audio could be taken from the fm_demod.grc flowgraph and fed to direwolf via a Float to short block and a UDP sink. https://gist.github.com/darksidelemm/… Thanks Mark.
I have spent days googling but found nothing with clear enough instructions for me to follow. I’m not a programmer. I usually come unstuck by not getting the path right, for instance I couldn’t find fm_demod.grc but I did find /usr/local/bin/satnogs_fm_demod.py. I know GRC can use this file but I don’t know how to get it out of the RPi SD card and into my Linux PC so I can use it to edit the flowgraph.
I have played with building flow graphs on GRC but I don’t want to risk stuffing up my working ID-568 ground station so I would need step by step instructions.
Thanks for your time and expertise.
