OK. Photos will come tomorrow, but a quick report. After powering it up, it
starts of in the initialization phase, then it locked and dropped out of lock
maybe 10 min after powerup. Then another 5-10 min later it had a longer lock
period which it dropped out of a few minutes later. I was watching the 10 MHz
as it was heating up using my HP5372, whos 10811 has been heater for quite some
I'll let it sit there with power during night and see if I acheive stable lock.
I would assume that it may need some attention such as trimming, but I really
would enjoy getting some facts from the serial port. Service docs anyone?
