Have you adjusted C217 while comparing the 10 MHz out of the 'problem child' to the 10 MHz out of one of your other 'locked' units? If so, and matched them as close as you can, and still it will not lock, I would contact the seller. Otherwise, it promises to be an in-depth learning experience that we all might benefit from.

Someone suggested I adjust C217 which worked, but if I jarr >the oscillator it will go I've run it at least an hour without a lock. Tried running it open and adjusting C217, but still no lock. I've opened it up and spun C217 in 45 degree steps--still no lock. I'm seeing about 80 mA on the 5 V input, 1.6 A dropping to about 620 mA on the 15 V input. Any other suggestions before I contact the seller? thanks! newell _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
