I have an inverted L antenna resonant on 80m, I decided to add a loading coil
to the base to bring it on frequency for TopBand. I wound a 2.5mm wire coil 16
turns on a bit of square Paxoline board by drilling holes into the board each
side and feeding the coil through the holes, a bit of a
Just chopped the fibreglass webs out and now no change, I would not have
thought it would affect this coil, so something else must have altered since
two days ago (Had to work) affecting the way the SWR is reacting.Pity, I was
pleased with the result, now to try to increase the Q of the coil
I think the fact that something positive is being done is working, even if it
is electrically futile it is definately putting some DQRM'ers off, the DQRM has
been noticeably less and with K1N ops and others reminding the offenders that
something is happening is a plus. The triangulation would
It's not that long ago when everyone would be raving about the Drake R-4C ,
so many pictures of top Topband Dxer's with one on the table, how times
change.

Very soon afterwards (a few weeks instead of perhaps a year), the
operator called me over to show me the problem with that switch. I know
what I saw, and I am convinced that it is abrasive. That grease
accelerated
the failure of that switch by a tremendous amount.
This is very interesting
Actually, that flies in the face of everything published about typical
silicone dielectric greases.
Tom,
I would tend to agree with you on this point, maybe it was the switch just
breaking down ( Only digital signals no high voltages) and the small metal
particles were causing further damage
Check out UKQRM on google, plenty of information there including soundbytes.
