Topband: Echo on 160m yesterday morning

[Herbert Schoenbohm]

Having worked LU and CX on 2 meters SSB (100 watts 7 element beam) 
without any ionospheric skip in the strange ducting FAI mode that is at 
time formed by the magnetic field at the equator, i say that anything is 
possible. But the idea of a  multiple moderate angle skip with so many 
hops around the world and twice is IMHO really all that probable.
