I will say that the fact that the actuality of the 5KHz lower than published frequency (Known for years) is the reason that often times you here a newby on the bird, throwing out his call, getting responded to but never answering back. I had a good QSO on HF a bit back, mentioned "I do AMSAT" and he said something to the effect, "I tried listening and calling but never heard anything". I told him about the "Actual vs. published" frequencies. He says "Well that probably explains it then". Even K6LCS's great pages at http://www.work-sat.com/Sat_Skeds.html do not refer to the offset. I am convinced that this disparity is the cause for at least some of the QRM on that bird, not all but some.

I use two frequencies for the downlink in SatPC32: 436.791 and 436.788 MHz. I have heard it suddenly jump about 5 kHz during a pass - but that is some time ago. The two frequencies above are not always spot on but close enough. Have a nice weekend all. OZ1MY/Ib _______________________________________________ Sent via AMSAT-BB@amsat.org.
