that location is probably where the coordinates were last saved. or there
abouts
Or those are the default factory settings from memory,
and new coordinates were never saved.
redo the survey and save
up with for altitude. If it's off by 100 meters, just
accept it and move on.

Thanks Stan,
I did that but I can't where to start the survey in TBolt. In lady heather
there
is a key for it.

This is not my first. Last one was more like July 4th.
Thanks,

patience.
The thing that surprised me was how much a TBOLT moved around compared to my
Z3801. Though it stayed within one cycle because it was phase locked, it
jumped around a good bit while the LPRO just slowly slipped in one direction
or the other.

I was thinking of feeding two 10 Mhz signals to two ports of a SBL-1 or
similar and taking the DC
output at the IF port into an opamp or analog meter. This was visually easier
to adjust the drift between two frequencies by just watching

Currently I am comparing the phase between two 10 Mhz and adjusting for
the lowest drift visually on the scope and phase drift on the Racall-Dana 1992.
Your suggestions I would like to use for calibrating the Rb oscillator
with a GPSDO.

to 10 minutes, painful to watch and adjust!

Hi
Which HP counter(s) do you have?
The method you are using now with a scope can give you good accuracy if your
clocks are close to each other and you watch things for a long enough time.

a lab, or just
want to get the Rubidium on frequency?

easier
to adjust the drift between two frequencies by just watching the needle move. A
stationary needle over a couple of hours would be the best!

Please be careful, chasing frequency accuracy can be an expensive obsession.

Hi! all Time-Nuts
a lurking infection in my shack !! I am enjoying and thanks for
the help.
I was using the Rb oscillator to correct the OCXOs in my counters. Now the bug
bit to check the Rbs properly. Will let you know off group!
