Hi David,
Skip Withrow and I were able to figure out the connections and the basic
operational features. I've attached a document that describes our findings.
I wouldn't mind picking up another
I'm certainly interested. I'm in the general zip code area, so I can pick up.
Call me at 714 402-1280.
Thanks, Tom

Sorry, didn't see the Oregon address. I'll happily pay for shipping to
California.

Thanks Ed (and Skip),
I've bolted the PCBs back together, and have it connected both via
SatStat and Ulrich's Z38XX. I'll let the oscillator cook for another
week and check the PN and ADEV, and if the E1938 looks good, figure out
the UT+ configuration.
Cheerio.
Hi David,
Skip Withrow
Hi Ed,
My E1938 also came from a very battered STLN4096A from the same source,
and I might also try to get the other boards functional. Could you share
the details of the GPS connections, and which GPS receiver you used?
Cheers,
david

Hi David,
Skip Withrow and I were able to figure out the connections and the basic

I wouldn't mind picking up another E1938 oscillator, but I'm reluctant
to buy one that might have mismatched oscillator and circuit
oscillates. Let it cool down and I need to repeat the stimulus
procedure. Anybody have any ideas?
Thanks,
Bob

Thanks, but I already found that. I've moved quite a bit beyond that.
That message was one of the few in the archives that had any
significant info on this unit. For some reason, I find that surprising.

OK, I wasn't able to find anything else. Moreover the STLN4096A seems to
have a Rb oscillator now from the usual 'bay vendor... so seems confusing
as the Z3817A may be the E1938A mounted on the PCB that can discipline it
or it is another type of unit or whatever else. No picture found until now
