Here is a summary of my testing

1. I could not get my ICOM 910H to produce a strong enough signal to prove my Signalink USB on 9k6 with soundmodem 2. I moved across to SDR - An AirSpy Mini and then a funcube dongle using SDR# 3. I Installed direwolf for windows and modified the config file to VB audio cable at 9k6 4. I Enetered my APRS-IS details as well 5. I started direworlf from the command line with the APRS-IS debug flag 6. I tracked Falconsat-3 manually in SDR# fitting just the passband 7. Direwolf through VB Audio started to finally pick up Falconsat-3

Improvements

1. Add doppler tracking to SDR# 2. Add turnstile antenna 3. Add preamp 4. Retire analogue radio idea
