The unit starts high and over 20 minutes comes down to 4.9999975 with 0 V on the EFC. Any voltage on pin 2 and it quits oscillating. Bert In a message dated 8/9/2012 7:06:48 P.M. Eastern Daylight Time, li...@rtty.us writes:
Hi As the unit warms up, you should be able to tell weaner it starts off above 5 or below 5 MHz. There are enough different crystal cuts that *might* be in there that checking it at turn on is the easy approach. If it starts low and is off low, the heater may be the issue.
