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.
