Con,
There MUST be multistrand wire that doesn't have this problem - hams have
been using the stuff for years. I'm not sure what AFAIK means, but I'd hope
it doesn't mean the multistrand stuff that home depot sells for house wiring
(pulled thru conduit). I've been happy with mine, and K1ZM used it in the
trapped vertical for 160/80/40 that's in "Low Band DXing". But I havent
compared it against a solid conductor vertical.

Subject: Re: [TowerTalk] 160m. Inverted L noise
Hi Jose,
I guess your "flexible wire" is a multistranded wire ('"litz wire")..?
AFAIK multistranded wire can develop the following problem:
the individual tiny little wires oxidize on the surface and this oxide film
acts as little diodes in between the individual wires, which
generates the noise when those little wires rub against each other.
might be what is causing the noise on your inv L.
of course there is no problem on TXing.
I suggest you try putting up the solid wire again and see if the
problem goes away... :-(
