Fellow clock-tickers,
Just a point of interest. I have successfully upgraded my Odetics 425
by replacing its original quartz OCXO with an Efratom (Ball) FRS-C series
rubidium oscillator.
The process was pretty simple: Wire the FRS-C in, with practically
identical wiring to the OCXO, and (since the bottom of the case is already
drilled and countersunk for an FRS-C) mount the thing. The only other steps
were to flip switch #2 on the MPU board's pack to ON, and (as a purely cosmetic
touch) to add a 'lock indicator' LED, driven by the FRS-C's 'Lock Indicator'
line.
Reassemble, power on, wait about fifteen minutes, and everything locked
up and behaved beautifully. It was ticking happily along even as I left work
this afternoon.
I see no reason why this trick should not work on any other Odetics 325
or 425. If anyone needs more details, let me know.
Happy tweaking.
