Fellow Topbanders:
I built a full size 1/4 wave vertical for 80 meters of telescoping
aluminum tubing, which I also use as a 5/8 wave on 30 meters and on 160
with base loading, all with remote switching through relays. Despite
considerable effort, I cannot get the thing to work on 40 meters now,
although it should work with some amount of additional inductance. In
fact, I had it working perfectly last week on 40 but now it simply won't
work on 40 (at the same setting that worked before and with no apparent
change in the inductance that got it to work at 7.00 MHz) and I am at a
loss to figure out why. The closest I can get it is 7.6 MHz, but no
lower. No amount of fiddling has made any difference. Any suggestions?
Thanks in advance for any help.
73, de Bob/AA6VB
