I have a weird one with my Z3801A. Screen shot from GPSCon attached. You
can see the EFC excursion... Maybe the oven in the OCXO is acting up???

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...
