[amsat-bb] how can I decode packet thru a Funcube?

I want to monitor a few satellites by using my Funcube Dongle Pro Plus on a different computer. I have a spare antenna, an M2 2m440XP ?

I've tried setting the FCDP+ to a frequency with their own controlling device then letting MixW or UISS/Soundmodem listen ... but nothing gets decoded.

Is this even possible?
