A few months ago, my 3801A started doing this.   It was tracking sats well (several years ago I had to replace the receiver because it had lots of problems acquiring and tracking sats).    I swapped in a replacement 10811 OCXO and that fixed the problem.

Apparently the problem with the receiver not tracking sats is usually due to the oscillator on the receiver drifting out of spec.  Some of them have an adjustment screw...
