I fired it up last night and it took about 2 hours to lock. This morning it only took about 20 minutes to lock. I guess I need to stir the electrons a bit more ?? It's sitting there on the counter, with a 1000 sec Gate time and it is as accurate as I can measure (BTW, the counter reference is a GPSDO - TrueTime). Looks like a keeper. 73, Dick, W1KSZ
