I've personally had good results with Belden 9913F7 cable outdoors in the west
(wet) coast of Canada for non GPS RF applications (two runs have been in
service for over 15 years.)
I seem to recall in the early 1990's using a different style of what I believe
was Belden "9913" cable that
that in some way it between running fast or slow the
gain/loss combination averages out over the course of the year?

Hi
A lot depends on just *what* the error actually is that’s popping up on the Rb.
In some
cases you have a VCXO that locks up to the Rb signal . The VCXO ages “far
enough” to
cause problems. Adjusting it can help in this case. You need to do some digging
to see
if your specific make / model
I get a proper picture

Potted! That just makes the challenge all the more interesting. Chip and
rip carefully. It depends on the potting but they tend to flake off
sometimes in nice chunks. The really hard stuff is no fun but can be done.

Hello,
Yes, this is a micro-D 9 pin female, usually quite expensive although
for 9-pin, there are some lower-cost parts available:

Attached are a couple of pictures of these curious oscillators. As there are

frequency adjustment in the rear under a cap screw.
