I am in New Jersey. Propagation from Colorado to here is probably similar to
Virginia.
This morning, Tues, 10/9, I listened to WWV on 10 MHz with the 4 antennas I
have at my disposal to see what kind of signal level I get.
My antennas are 80 meter and 40 meter dipoles, a 20 meter yagi and a 30 meter
dipole, all at about 50 feet.
On the first 3 antennas WWV runs about S6-9, and on the 30 meter dipole it is
10-20 db over 9.
This evening, 6 pm, the first 3 antennas haul WWV in at S9 and the 30 m
dipole has it at a rock solid 30 over.
So I agree with the advice you got to string up some kind of dipole and throw
out that loop, there is plenty of signal, you just have to go get it.

PS may I throw in a little commercial for my pet peeve? As you read this did
you notice that I did not include any text from previous posts? Did you miss
it?
