It might have happened before on some of the Mode K satellites, due to F2, 
but not sure if the other modes would work below the horizon, as getting the 
conditions right on both bands would be pretty tough.  Tropo wouldn't get 
high enough into the air to get into the satellite.  Has anyone heard AO7 in 
mode A when it is below your horizon due to F2 skip extending your range of 
the satelllite?
