Stuart -
Checking beacons was the first thing I thought of. But, if I can't hear a
beacon, is it propagation or the rig?
This is what I hear at 0000UTC - 7 PM EDT Thursday
Beacons -
15M - 4X6TU (S2), OA4B (S3), 4U1UN (S1) only
12M - OA4B (S1), 4U1UN (S1) only
10M - 4U1UN (S1), LU1FHH non-system beacon on 28.200 (S1)
SH/WWV on the DX-Cluster shows a sunspot number of 145, so I assumed
(incorrectly?) that I should be hearing good signals on 15M, anyway.
The antenna is a dipole (100' per leg) which I re-strung and re-soldered
last week. There could be a problem there. Feedline is twin lead to a
balun to an LDG tuner to the rig.
I may bring down the antenna and check the connections.
Thanks for your suggestions.
