Trying.. and failing amateur satellite contacts / 2014-07-24

2014-07-24 Trying.. and failing amateur satellite contacts 5 years ago
Yesterday evening I gave it another try to make a contact via the SO-50 satellite. It was hard since someone was trying very hard to work the satellite with 95% transmitting and at most 5% not transmitting which did not leave much room for an answer. I heard that person loud and clear with a repeated and somewhat bored "CQ satellite" and testing noises like whistling, but I never heard a callsign! Pass for SO-50 over my home location JO22NC

Trying to answer that person didn't work (clearly he had a reception problem somehow) so I just started calling CQ on my own when he left a gap. Someone answered but I had a hard time understanding the callsign, I think it started with a D (German callsign) and I am sure it ended with BBE (Bravo Bravo Echo). Looking up the callsign options on QRZ showed me the most likely candidate is DG0BBE so I e-mailed him to confirm.

During our holiday in Denmark I also tried to work a few SO-50 passes. Being on a campsite with a wide open view in all surrounding directions should make things easier for lower passes which I skip at home. I tried a pass with a 55⁰ elevation and one with a 62⁰ degree elevation and I heard the satellite loud and clear. The downside was someone was whistling and calling 'o la', probably the same person as I heard here at home. And another downside is that with lower passes the distance is a lot higher and therefore my 5 watts on VHF don't make it across the FM receiver on the satellite.

I also had a look at possible LituanicaSAT-1 passes but in Denmark those all stayed low to the Southern horizon.

Update 2014-07-25: DG0BBE mailed me back, I was right I heard him, but he made a very valid point the QSO was not valid: in a QSO at least call signs and a signal report need to be exchanged. In amateur satellite work a locator is also good to have.
