Both with masthead preamp. Radio was an FT-847. I can remember working AO-07 (cw only) down to very low elevations, FO-29 and the Indian satellite (sorry, can't remember the number right now) where the easiest with some passes available also for SSB QSOs. AO-27 was easy to work when traffic was not high, also SO-50 was workable and of course the ISS trasponder. 73 de IZ8DWF _______________________________________________ Sent via [email protected].
