Hi Dave,
It's an HF9V, so not really a "trap" vertical per se. It's perhaps 2 yrs
old and still in nice shiny condx. I put it together with copper paste as
well and there's still lots on it.
I've also tried to transmit on other antennas I have here as well (low
CC-A3, 160m inv L) on some other band combos with other stubs etc. and no
real change with stubs on the transmitter.
I am just trying to concentrate on the single 40m>20m QRM issue. (so as not
to muddy the waters)
Once I get that hammered out, I can probably find my way from there.
Tnx much..and yes, I practically have your page memorized by now, hi !
(One of )The reason(s) I am going round n' round is:
A) Stubs do nada
B) Two prominent stations.one in EU, one in NA say I am doing it
backwards.
Thanks all
Mike
It's a multi-band vertical... ugh... how long has it been since you took it
apart and cleaned all the connections?? I had a tribander here that caused
all sorts of harmonics, even when it wasn't connected to anything, bad
connections to traps and between tubing causes all sorts of bad things.
Also, this is just the single stub, not the pair that does the 3rd harmonic
of 40m-15m?? so it should only work on the harmonic from 40m to 20m or 10m.
