I had earlier reported that vibration had a phase shifting effect on Rb
unit. Some of you gurus has suggested that something may be loose.
I checked all the mounts and found that the lamp side mount 4 screws
were loose. I tightened them with a small screw driver taking care not to over
do it.
The vibration problem did not go away, but the Rb unit is now
surprisingly stable w.r.t. GPSDO. I will check another unit tomorrow and
report. I think that high temperatures will cause physical material changes
that may do this.
Have any of you checked the 4 screws on the lamp and found similar
loose screws?
