The program says this coil is resonant (?) at 10.120 mhz

Now here comes the really dumb question - will this cause
a problem on 30 meters? I seem to hear OK but I've not
yet tried to make any contacts...

My SWR meter indicates a 3:1 SWR there but my nifty
Z11 autotuner tunes it just fine.......

What am I not understanding here?

Hi Ken,

Not much reactance overall for one. I've lost track what bands you
want to work, but the SWR would suggest not much Q either. There is
also the matter of how long your cable is too at any particular
wavelength; at some lengths, like half wave, it just doesn't matter if
you had a choke or not (the radiation resistance would snub the
current anyway).

You got 3:1 for any number of reasons, but your tuner took care of it.
That's what a tuner is for. [However, as a solution it is unrelated
to your original problem of a hot coax shield.]

Feeling a little chagrined at accelerating the super glue bond? ;-)

Offhand I would offer that you are probably out of the woods. Just
leave it alone barring repeated symptoms that lead you here.

I have used baking soda as an accelerator for years - works great
everytime. Just don't let the puff of smoke that comes out get into
your nostril membranes or your eyes..... nasty reaction, then!

Winding the coil had several good effects:

1) No more rfi in my PC speakers
2) No more fluctuating SWR readings
3) More consistant (and faster) autotuner action

So, it works - thanks to all the advice I got here (it really
makes me feel like the tech + KB0PWC I started out as),
I've got a viable radiation system.

I'll have to wait for the winter 160m season to see how
well the system gets out on that band - W7EL Roy suggested
I model the antenna on EZNEC and compare the resonance
points and SWR bandwidth. I think (?) I have the program
figgured out and it appears his worry about the bricks in my
building effecting the antenna are somewhat proper.

However, the performance of this antenna in the AM broad-
cast band is SUPERB! I'm hearing stations all over the band
at night, from as far away as Chicago and Los Angeles. So
I've got hope the antenna won't be a complete flop on 160.

Last night I worked several of the Ohio QSO party stations
on 40 meters with many amazed at my "QRP with a wire"
setup...... not to bad from Colorado.....

Hi Ken,

Not to rain on your parade, but as a teenager in Colorado Springs,
back in the 60's, I had a 50' longwire traced along the fence rail at
roughly 6'. I could AM DX both coasts on my RBB-1 (WWII shipboard
receiver which weighed as much as a pocket battleship).

That just reassures me I'm on the right track. I'd have picked
up more stations but they were all on top of each other in a big
jumble...

Not to rain on _your_ parade g, but, back then, licensed radio
transmitters were about the only "radiators" you had to contend with.
(Well, maybe not in the 60's -- but, I remember the 50's....)
Oh for the days when you could tune to an unoccupied frequency and
turn both the AF and RF control up to max and listen to the cosmic
background.

The other thing that killed radio and TV DXing is 24 hour stations. I used
to do TV DXing from Ohio. Turned the antenna East in the morning, and West
at night (when the locals were off). Picked up stuff from New York City to
Pueblo Colorado, and London Ontario to Santa Clara Cuba. The long haul was
all channels 2 & 3.
