Hello Mark;
The RTLSDR runs fine on this machine withSDR++ or SDR#... So I'm not convinced it's an RF issue.. AS to receiving the sonde.. NO..
I tried both programs and cud not see anything other than the birdie at 403... the sonde is running at 403.2 so cud be an issue..
I tried the Native just for shiggles as I was getting no where with the Docker program.. on any computer I tried and antenna selection..
so it's gotta be in the program somewhere on the computer or the RTLSDR.
I was talking about the local host web server.. could connect to the program.. When I ran
sudo journalctl -u auto_rx.service -f -n
Errors and WARNINGs all over the place. Happy to screen shot that if you think it would help
