[Skimmertalk] Anyone got this to work?

Ted et al.,

Just to review, there is a much simpler way to generate FT8 spots from a
Red Pitaya.  You do NOT need to run FT8Startup, CWSL_SSBWave, Virtual Audio
Cable (VAC) or any other programs on Windows, not even a single copy of
WSJT-X.

The FT8 decoding logic and almost everything you need is already
pre-installed on the Red Pitaya SD Card (in Pavel's Alpine Linux
distributions), ready to be enabled.  The only downside is that you do have
to dedicate a Red Pitaya to FT8 decoding, since it can only run one one app
at a time, either sdr_receiver_hpsdr (for CW/RTTY Skimmer) or
sdr_transceiver_ft8. but not both at the same time.

But buying a second Red Pitaya, or using an older one, is so much easier
than setting up a Windows machine to do multi-band FT8 decoding, plus you
don't have to worry about WSJT-X filling up your Windows hard disk with
.WAV files.

The Red Pitaya FT8 app. automatically reports what it decodes to
PSKReporter.info, and can "optionally" send the same reports to the RBN via
the Aggregator, with no other Windows software required.

SM7IUN has excellent documentation explaining the procedure in detail,
including handy setup scripts that automatically rotate between any 8 bands
for day, night, and dawn/dusk.

I would strongly suggest trying this alternative before investing any
effort into doing the same job on Windows, or buying another PC.  Just
follow all the steps, or if you get stuck, ask for help here.
