The GC-1000 keeps declaring the decoding to be invalid partway through
each minute.
Dean's synthetic WWV gets decoded perfectly and the display turns out
after 3 complete
minutes. But the 100Hz level in the synthetic sounds high to me. Since
your recording
fades in and out (just like I hear it in LA!), I need to figure out if
the clock is
having trouble pulling the 100Hz tones out, or if the recording just
fades too much.
I'm injecting the audio at the volume control, so this is past the AGC,
so there's
no compensation as the audio fades. Perhaps that's why I can't decode
your audio.
Gotta pull out the schematic again and study it.

I'm trying to track down some problems with my Heathkit GC-1000 clock and
it sure would be nice if I could inject some known good audio
recording and see if
the clock picks up the time from that.
I've found a couple recordings by googling, but they are both too
short to be useful.
Try this:
(Rather noisy; WWV-5 just now; WWVH-5 in the background.)
