[amsat-bb] New Telemetry Decoder for FalconSat-3

[Graham]

Chris,

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
