Thanks, what has me puzzled is I have S7 noise on 10 meters and with the loop
antenna, I believe I have it tracked to a utility drop for a house 2 doors
down; however I don't pick anything up on 2 meters or 440.
Perhaps there is something in the house that is generating the noise, that I
will be able to locate when the owner gets back to me. Once inside, would you
recommend using the loop or perhaps just the Tecsun with the built-in antenna?
Appreciate the help, I've tracked down a couple poles in the past, which PG&E
confirmed and repaired, but something is different about this one.
