Henk, Was the pass high or low elevation? I had a pass this morning, all in high power mode, with a 55 degree maximum elevation. Before TCA, I was able to access the transponder easily. After TCA, it was much harder at the same ranges. The CW and TLM signals were about the same. It is spinning, but that will be around an axis. I am wondering if some of the reports of the transponder being off may be due to the short UHF antenna being blocked in some orientations?

Can someone point me to the ARISSat-1 mode schedules ? During the recent pass, ARISSat was the first pass in low pwr mode. During the (short) active periods I could relay short CW beeps over the transponder @5W. Midway the pass the satellite came in the sun and switched on and stayed on. But now the transponder was off. Is there an overview of sequence of modes, eg when SSTV is on Xponder off, etc. ? Henk, PA3GUO, _______________________________________________ Sent via AMSAT-BB@amsat.org.
