[ICOM] 765 freq problem

[Marc & Tricia Niebergall]

This may have been discussed in past threads, but I could not find it, so:

My 765 drifts off freq by approximately 150 hz.  This happens in a matter
of a few seconds. It will sometimes drift back. This affects both tx and rx
alike. I have been told it is likely in the reference oscillator.  Does
anyone have any experience with this phenomenon?  If so can you point me in
the right direction for troubleshooting?

Thanks,
