Ah, well. I have also received two Lucent KS-24019 L106B, aka
RFTG-m-XO boxes. The serial numbers indicate 95 and 96 construction.
The assembly numbers, 55761ASSY103902-001 (55761 is the CAGE number
for Efratom) have Rev E, S/N 522 and Rev H, S/N 2385.

Hallo Robert,
Voor de 5061 had ik 200 Euro in gedachten. Als spare parts unit.
Tot nu toe weet ik dat de 2.5kV defect is. Gaarne in Amersfoort afhalen.
Verzenden is erg duur denk ik. Er zijn imiddels ook andere die interesse
hebben
in de unit. Ik geef jou de eerste keus.
Alsvast beste wensen voo

Has anyone used any of the following signav receivers for timing purposes.
They claim to actually correct the sawtooth error in hardware.

Hi John,

in frustration for an image and I'll learn more by sticking with it for

It is: The 2nd style is wider than the oscillator and has a 10K pot along
with two adjustable caps anduses a voltage regulator mounted on the rear
standoff, and is usually what you see on eBay.

In looking at the two units, both use the same main and "mezzanine"
board, but there are component differences.

Can you clarify your question a little?
There are two different styles, one that is the width of the oscillator
(approx) and has no adjustments, the only adjustment that can be made is on
the oscillator itself. The 2nd style is wider than the oscillator and has a
10K pot along with two adjustable
Just like with wine, making good crystals involves a lot of knowledge

Following the recent discussion of the positive effects of the M12's

Hi Rob,
I came up with the same results, but no links to data. Most hits are selling
surplus stock.
I did spent 2 hours trolling through many sites hoping to pick up something.

Gerald,
I did a search on Google using OC2545DT-1000 (excluded Murata) and found a
lot of results, although all seem to be companies selling product. There may
be a link or a further contact if you dig deeper.

I don't believe it's mentioned anywhere in the 5345A manual, but I'd guess
it's in the 10811A manual. Of course, the counter may not take advantage of
the entire available EFC control-voltage range.

Thanks for the good news! I foresee a late evening with plenty of time
