A little later FO-29 was due over and I wondered if I might be able to hear anything. The pass was quite quiet, but I did hear my Twitter friend, Berend, PA3ARK on CW. I was able to find my signal and place it reasonably close to Berend's and we had a bit of a sketchy, but valid QSO.
Really pleasing to find that some simple CW satellite operation is viable with just a vertical antenna.
Berend sent a nice photo of the entry of the QSO in his logbook!
Evening update: I caught a late afternoon pass of VO-52 and was hearing myself well enough to have a tune around and was able to answer UT3UX who was calling CQ on CW and work him. I've not found too much CW activity so far. I'm sure I can work some SSB, but with the slightly lower signal levels, CW gives a bit more latitude!
