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?
