Re: [amsat-bb] SO-50 Frequency Drift

Quoting Paul Stoetzer who wrote on Sat 2014-05-31 at 12:42:

Just was on the last pass of SO-50. I was not hearing the satellite at first even as it rose above the trees. At the middle of the pass, I was expecting to find it at around 436.795 MHz, but I found it around 436.786 MHz.

Has anybody else noticed this?

I just had a pass (and worked PD5DJ, thanks!) and I also noted a downward shift in frequency as I had to select the next downward shifted frequency earlier than gpredict was showing. Gpredict has the default 436.7950 in its configuration.

I can't give exact numbers as I was busy trying to hear/make a contact but there is some downward shift.
