The other issue is whether your clock is actually able to synch with
the WWV signal... You may have a defect in the clock... It would seem
that 4 or 5 bars should have done the trick...

Presumably the LED meter indicates recieved power, not signal to noise
ratio.

That's good!

Polarization was one of my thoughts.

Also, how is the synch tone derived by the receiver? Maybe that part of the
radio needs tweaking? One would think that seven segments out of ten should
be sufficient. I'm assuming there are ten segments total.

Since he said previously that he could hardly hear the tones/voice, isn't it
probable that the receiver is just seeing mostly noise?

As mentioned by someone else, propagation is currently "very ordinary" (aka
poor) at present, so maybe he's just out of range.

I'm just trying to be helpful, not a wiseguy. Although it does seem that my
genetics predispose me to lean in that direction. G

Owen,

Thanks for the comments.

Exactly. It's an LED bargraph driven by pin 9 on the TDA1072A chip;
according to the data sheet that's the "Field strength indicator
output", a log-scale output driven by the internal AGC amplifier.

I got a clearer WWV signal the other day and was able to re-tune my
antenna. It turns out that the "loud signal" I was tuning to wasn't
WWV, just some random RF I was overloading my poor clock with. The
bargraph now sits down at 1-2 LEDs most of the time, although I did
see a "bursty" period this morning where it went up to 3-5 LEDs.

The WWV audio was coming and going on about a five-second interval:
louder (almost clear), then softer (almost to disappearing), then
louder again. "Wow", so to speak. grin!

Ah, well. Maybe in my Copious Free Time I'll replace the MAC-II's
87C52 with something I understand, like an AVR, and program it _my_
way. (Oh. Then _I_ get the support calls. ... Ack!)
