[time-nuts] Trimble GPSDO board

[Bob Benward]

Arthur,
I did read your posts before I composed my email.  You made no mention of
getting the RS-232 to work, and you made no mention of the MACT switch.
Yours worked from the start.  I am not having such good luck.

I got it to lock once, I notice the 1pps comes out almost immediately, even
after being off overnight.  I thought this output was a result of GPS lock
and this locked in less than 10 seconds.  So in my case, it still has locked
only once, and I don't see anything coming out of the serial port, so it's
difficult to make any other evaluations.  The green activity light is on
solid then after the oven reaches temp (the current draw goes down) the
light starts blinking.  The output from the oscillator is there, so I will
X-Y it with my Z3805A and see if the oscillator is truly locked to GPS.

Bob
