[OZAPRS] [amsat-bb] FalconSat-3 sig level to decode

[Andrew Rich]

Ken 

Could you give me a hand

I have falconsat3 packets coming in on sdr#

I am using soundmodem but then the packets don't go anywhere

Can you help me get direwolf running on windows so I can pass them to the aprs-is

I am trying ui-view but I don't think it know what to do with the packets

Still looking for a good sdr# doppler solution 

I have a few things up my sleeve yet
