I had answered a post earlier this morning about r-7 not resonating
anywhere's but 10 meter.
black box is not at fault, as it works on 10 meter, so antenna is good up to
10 and then high swr on all other bands.
I did say in that post that it was the 15 meter trap,,, sorry but meant 12
meter trap, just a typo, doing this left handed only as I just got out of
surgery to right shoulder, does hamper my typing some, hi hi
also check all other traps to make sure that it is the only one to not work.
funny how a little bit of corrosion will cause a lot of problems.
it was fun fixing after finding problem and has gone thru a tough winter
with strong winds,, all still works good and looks great with guys on it.
