I have heard satellite paths extended by Aurora many times. It has very distinctive sound.

I was giving a presentation at our club meeting called Working DX on the Satellites and afterwards someone had a good question: is it at all possible that tropo, skip, or other form of enhanced propagation can enable a contact via a satellite below the horizon?
It has never happened to me. Has it ever happened?
My memory might be a little fuzzy here. There was an article in the AMSAT Journal back in the early 90's where G3IOR described his contact from the UK into VK/ZL using RS-12. As others have mentioned in this thread, RS-12 using 15 and 10 meters for uplink and downlink, below the horizon contacts were possible. I was able to work KH6 that way from New York. I also worked many European countries out of normal expected range.
I seriously doubt that satellites using 2 meters and higher frequencies for uplink/downlink would show much (if any) below the horizon capability.
