Have two Z3801A receivers by HP and a Racal-Dana model 1992
counter timer with a Phase A-B function. Measured the phase
between the two 10 MHz outputs of the receivers and got
values between 250 and 350 degrees with 2-3 degrees noise.
The receivers are from the same production run. Each has its
own HP antenna. The antennas are four feet apart on a mast
of six inch plastic pipe. Usually, six satellites are active
with signal strengths above 150. The lead-in is 50 feet of
RG-8 for each antenna.
They have been running for two days now, locked in 40 hours
ago. Why is there all of this phase shifting?
