I had the exact same problem as yours. I discoverd that my 106B had a 6-channel board in it vs. the 8-channel that is supposed to be in there. I put a 8-channel board in and the fault and GPS lights went out. - Original Message - From: "Robert E. Martinson" <[EMAIL PROTECTED]> To: "'Di

[time-nuts] RFTG-m-XO experiences

Hi All; I'll give my experiences with my RFTG unit. I bought it ($$$) last fall from an ebay seller who moves a lot of time and frequency related items, it won't take much imagination to figure out who I'm speaking of. I believe he is an honest seller, and I've bought from him several times and

Thanks for the quick responses, Jim & Phil! No, I was running the XO unit all by itself. My guess is that the XO should be able to run all by itself??? I have previously run with the XO & the RB interconnected (J5 & 10 MHz Ref). Not for 24 hours, but at least over night, but No GPS stayed ON o

Over the weekend I left the XO unit running for 38 hours, with it installed in its "house" (No probing). The GPS receiver was tracking satellites at the start and also at the end of the run as verified by monitoring J5-2 w/VisualGPS. The Fault & No GPS LEDs never went out. I'm about to conclude
