Bill, If it's an older clock it's probably tripping over a timecode transmission format/modulation change. I forget the exact details but changes were required to my old 8085-based Spectracom receiver.
Thanks, that's probably it. I assume if I build one of the W8BH WWVB clocks that problem either has been or can be fixed. OH well, the clock I have was a gift to my father long ago when I first got him into ham radio. It still serves to remind me of how much I miss him. Thanks again. bill KB3YV
