Re: [amsat-bb] FalconSat-3 sig level to decode
I'm using the AirSpy (not mini) with SDR#. Doppler tuning with homebrew software. Haven't noticed lost packets when the SDR freq changes, but will be on the lookout for that.
The audio loopback is Virtual Audio Cable.
SSB Preamp
Rotator is a G5500 and LVB Tracker controlled by my homebrew software. (I really like the LVB Tracker!)
Sound modem is Dire Wolf which feeds APRS-IS. At the present time I'm just watching the packets scroll by on the Dire Wolf display. My main goal was to Igate the FalconSat-3 packets.

On this morning's FalconSat-3 pass, I checked the signal required to decode using Dire Wolf. It was 18 dB SNR, so that's roughly S3 +/- above the noise floor.

G5500.

It's the AMSAT LVB tracker. Wasn't aware there were others.
