Listening to an SSB amateur satellite 5 years ago
I had a chance Thursday to listen to a pass of the AO-7 satellite. Passes of this satellite take longer than those of the SO-50 satellite. The AO-7 satellite has an inverting transponder for SSB operation so I have to search for downlink signals. I heard some: mostly CW (morse code) but even some weak SSB. To weak to make out callsigns (for me) so this will need practising too, just like I had to learn to hear callsigns on SO-50 in FM mode.
