I also noticed this several years ago. I have 3 d/l freqs entered in
SatPC32. 792, 795, and 797. I don't recall  having to change the d/l
lately, but I also haven't been working the birds much...

Hi John 
I have also noticed this deviation in frequency since a long time. 
Already put up two frequencies in the Satpc32 CAT, and 346791.0 and
436795.0

Assunto: [amsat-bb] SO-50 Frequency Jump

Over the past week or two I have noticed that SO-50
is changing frequency during the pass.  Today at 2308z
I made some transmissions and then noticed that my
downlink was distorted as well as the station I was
working.  A change from 436.790 to 436.795 for the
center frequency (not the doppler corrected frequency)
made the audio clear again.

This has happened to me a few times now and seems to occur
once the transmitter has been on for a minute or two.  Has
anyone else noticed this?

73,
John K8YSE
