Hi everyone,

I am building a WWVB receiver for my Applied Signal Processing class and
I'm having some trouble that I think some people here may be able to help
with. I had it working fine several days ago in northeast Pennsylvania(I
was getting a strong signal, at least 12dB S/N ratio and I could hear it
loud and clear). When I came back up to New York (Ithaca, central
southern-tier,only 100 miles away) I haven't been able to get it to work
(I've been trying since about 11pm last night and I get no signal at all,
just quiet static, as if the transmitter were off the air). I have checked
over the wiring and I don't think anything has changed. I am also able to
hear weak signals from computer monitors in nearby rooms and my own monitor
saturates the audio output so I think it is working.

First of all, can anyone who has a WWVB receiver or self-setting clock tell
me if you have received a WWVB signal in the last 12 hours(from 9:00 until
21:00 Wednesday 18 April UTC)? They have been doing antenna repairs lately
and have had some outages, so it is possible that they have been off the air.

Secondly, my understanding is that in most of the continental US, WWVB is
received through ground-wave propagation (it's at 60kHz) which should have
no problem entering a valley which is several miles wide, right?I know that
my area is well within the stated coverage area for at least a large part
of the time I have been listening.

Thanks,

Sean
