An update:
Before I could get the Rx on the bench to check things out, it stopped
doing this freq shift thing. I can't cause it to do it again..so for
now, nothing to do but enjoy the rig!

Good Afternoon All:
Back from the summer off..
Fired up the B twins after a 3 month layoff and the frequency of the
R4B is jumping regularly about 16hz. It stays steady and at intervals
of approx 1-2 seconds, jumps 16hz for about a 1/4 second then goes
back to the original. Both the original and the jump-to frequency are
very stable. I have not seen this behaviour before on any of my
Drakes. The problem is not there if I switch to Tx control. It does
not appear to be mechanical since I can not aggrivate it with
vibration or tapping.
This R4B HAS the braid applied to the VFO slider and it has been
cleaned and operating well prior to the layoff. No re-seating of
tubes or other actions (switch or control settings)seem to eliminate
it and it is apparent on all bands.
Seems to be fine in all other respects.
Any Ideas?
Thanks
