I'm about 680 mi. straight north of Fort Collins. About a year ago, I
got an Odetics WWV receiver that remembers the reception results for the
last 7 days. It tells me that the only time it can get a lock on WWV @
10 MHz is between about 0800 and 1800 hours. It never gets a signal in
the evening or through the night. The antenna is an active ferrite rod.
I think I remember that, years ago, the situation was reversed. You
could only hear WWV at night. Does your clock only listen at certain
times of day?

The second recording still did not get the clock to sync.
So I tried an all up test, setting a WaveTek 288 signal generator to
5Mhz at -47db,
and used your audio to AM modulate the signal. This gets the AGC amp
back into
the picture. And it successfully decoded, saying 10:15 PST!
The synthetic recording also worked via RF.
So I guess I'm concluding that the clock had some bad electrolytic
capacitors, which I
fixed, and I'm now going through a crummy reception period for WWV. I
used to be
able to get WWV on 5 or 10 Mhz overnight with just a wire strung out
from the clock,
but that doesn't seem to be cutting it anymore.
Thanks for the assistance.

There was a lot of fading present; possibly too much for the
receiver to work with.
Try this recording instead:

Still some of the usual fading, but not nearly as bad as the
other night.
