It would be great if signal received during DOA could be accessed via network by other app or host for demodulation, waterfall etc. Ideally via some widely supported protocol, like rtl_tcp.
I agree! Including support for using DSD+ would allow multiple demod options.
APRS output, either serial to a tnc or via web to aprs-is, would also be useful.
Yep this is something we are looking at doing as well.
Not sure if there is enough CPU power left on a Pi4 to handle this though, experiments will find out.
