FS-3 is a complicated topic because there are a lot of moving parts and
everyone's hardware / software setup is different.
The key items to get straight are RX-audio, TX-audio, & PTT. All that
comes together and it controlled by the UZ7HO High-Speed Soundmodem app, as
As a starting point, I'm happy to share the settings that work for my
particular RX / TX / PTT setup. Here is a picture w/ comments:
... but of course there is a lot more to it. We need to have everything on
the RX & TX side set with wide enough audio bandwidth to handle 9600 data,
we need to have a COM-port controlled PTT relay, and yet another COM port
ID is assigned by the computer via the "HW Virtual Serial Port" app to give
the WiSP (MSPE) software what it requires. If that's not enough, since the
downlink is constantly transmitting, the "full-duplex" option in UZ7HO
HS_Soundmodem needs to be enabled.
But as a first step, I hope that the picture of my settings might ring a
bell and help you realize what is not working exactly right in your setup.
Lastly, for anyone not familiar with FalconSat-3, a very neat feature is
that the APRS digipeater -and- BBS both work at the same time. So, you can
use something like UISS to send/receive APRS messages, WiSP or the new
PacSat Ground Station to upload/download messages posted on the BBS, or
both at the same time. All the traffic from both spacecraft services is
riding on the same full-duplex 9600 data stream, so both services can be
utilized by multiple operators all at the same time during a pass.
