pleased to find that by using my tuner I am able to tune it to most of
the HF bands. I tried it out on 30 meters this morning and although I
was not able to get an answer to my CQ using PSK31, I did get picked
by the KB9UMT robot and was immediately auto posted.

oversized wire antennas. Whether I was able to get up an end fed wire
(sometimes zig zagging it) or a loop, or dipole they all worked well.
I also found that I must keep the power under 20 watts using such an
antenna system. It seemed that if I went over 20 watts then I would
have RFI or RF feedback or some other problem.

> 73 all, Glenn (WB2LMV)I have a 450' (approx.) loop running through the trees, varying from
10' to 30' up. I bring the ends through the wall of a detached garage
and then to a choke balun on RG8 cable consisting of ferrite toroids
that slip over the coax ( two BA-8 balun kits from Palomar Engineers)
and then to an MFJ 929 Intellituner. There then is a 100' run of the
non-contaminating version of RG8 from the garage to the house and then
to the shack. It tunes up nicely on 160-10 m. and works well. I've
always wanted to try a big loop like this and finally have the real
estate to put it up. I run 50w to it from an Icom 756Pro3. It works
better since I put the choke balun on the antenna side of the tuner.
The balun should keep stray RF out of the shack.
