Drew, I believe your reference was to N4ZC.

There are some old (2002) posts on amsat-bb about his exploits: http://www.amsat.org/amsat/archive/amsat-bb/200203/msg00005.html http://www.amsat.org/amsat/archive/amsat-bb/200202/msg00708.html http://www.amsat.org/amsat/archive/amsat-bb/200202/msg00712.html

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?

It was relatively commonplace with RS-12 on Mode K, 15m up, 10m down. There was one guy in North Carolina I think that worked dxcc on RS-12/13. He was my first satellite QSO in 1992 or so, and was always on. I can't remember the call, but it was a 1x2 I think.

I imagine it would be at least possible on other birds and higher bands with strong tropo. Jerry, KK5YY told me about doing that on AO-27 or UO-14 from Alaska over the ocean. I've not experienced it though.
