thank for posting this and all your work.
I monitored an early morning pass at my location (around 2019-02-09 12:56) and noted good signal strength.
I am using a simple 70cm turnstile with mast mounted pre-amp, airspy mini, and SDR#.
Also, using high speed HS soundmodem configured for G3RUH 9600 baud all configured following the description in the pacsat ground manual document.
SDR# has audio filtering turned off as I do for use with the FOX sat programs.
So far, no decodes.
So, my primary question as this point is - what mode should the radio bet set to? NFM? WFM? USB? Bandwidth? I am currently set to 15kHz bandwidth.
I automatically correct for doppler.
cheers, Graham ve3gtc

I've written a new Ground station for FalconSat-3. If you had an initial go with WISP without success or if you have never tried to decode FalconSat-3, now is a good time to try. This requires much less setup than WISP. And don't be put off if you don't have a hardware TNC, this will work with a soundcard TNC. Or, if you didn't try to listen to FalconSat-3 because you don't have a station that can transmit commands to the spacecraft, then read on. We still need your help to decode telemetry.
In particular we would like to encourage people to download the Telemetry and forward it to an AMSAT telemetry server. Currently more telemetry is generated than we can download with AMSAT Operations ground stations. Receive only stations can contribute to that as well as stations equipped to transmit to FalconSat-3 and request files. You can see telemetry uploaded so far here: http://tlm.amsatfox.org/tlm/FalconSat-3
There are details about the spacecraft, how to install the software and how it works in the manual available if you download the software or online here: http://www.g0kla.com/pacsat/pacsat_ground_manual.pdf
You can download the software at www.g0kla.com/pacsat/index.php. I have also written some blog posts and thoughts about the software for anyone interested. They are linked from the download page.
There is much to do here of course and most of it probably won't get done. I would call this a beta release. If you have suggestions or bug fixes please log them online at https://github.com/ac2cz/Falcon/issues or send me an email.
The software is open source. All the details are here: https://github.com/ac2cz/Falcon/ The telemetry processing and display leverages common code from FoxTelem in a library here: https://github.com/ac2cz/libTelem/
