I noticed the Lucent RFTG-U has mounting for a Motorola type GPS module.
Has anyone successfully mounted a GPS module in a Lucent RFTG-U and got it
working?
Different firmware?

Azelio, I had an interesting experience with the same symptoms tonight.
I inserted a 6 dB pad on the antenna input and it appears to alleviated the
problem.
Perhaps the GPS module is being overloaded with too much signal?

Funny timing. I am working on a 10811 from a z3801 and am working towards
opening the can its soldered. Steve Smiths posts have been very helpful.
But I am dealing with lots of black melted goo. Not really from heat. Just
age the way a lot of things deteriorate.
That said I will be trying to
Paul,
If the 10811 is that far off, are you sure the oven is working? A
few years ago mine had a failure of a particular date code range of
the opamp that controls the oven, that were prone to failure.at high
temperature. The symptom in the Z3801A was that the outer oven seemed
bad - it did
Hi
If a 10811 oven is simply not working, the output will be 400 Hz off
frequency.

Hello to the group.
As the various posts mention pulling the outer oven and taped wire off is a
job. But thats done.
The Osc is 45 Hz low hot and 200 Hz low cold. Bobs on target with his
comment on what to expect. It does warm up and behave as you might expect
but its all relative not exact even
I moved my Trimble bullet up the pole to have a 360 degree unobstructed
view and now the AMUs for the SVs are reading in the 39-50 range. Is this
too high or normal?

The original post has updated Circuit (different transistors and less minor
changes)
Also now included is the circuit of the inner oven controller.

I did a quick check of the antenna current on a normal (un-attenuated) vs. the
attenuated receiver:
Normal:
Antenna current: 26.470589
Attenuated:
Antenna current: 32.352940
Slightly higher, but well within range.

Hi
Pad = resistor in series with the dc. That will drop the voltage on the amp in
the antenna. Not a good idea.

Bob - Pad is connected between Distribution amp that powers antenna from
separate supply. Good idea.
I haven't bothered measuring the voltage at the output of the pad, perhaps a
simple calculation for you?
