[TenTec] Eagle Tuner

I've been a little fuzzed up with computer problems - think I missed some of
the discussion.  I use a center fed zepp, 130' long, fed with 450 ohm 
plastic
covered open wire.  It's fed through a big military surplus balun, big 
cores,
inside an sealed aluminum box outside.  4 or 5' of RG-8 out to that from a
TT 238 tuner.  It loads well on almost all bands, and seems to have a decent
signal, as shown in the recent W1AW/KY exercises.

I also have a Cushcraft Mini-beam at about 40' which isn't great, but gives
a little boost.  Ten-Tec Hercules II matches up well with the Eagle, and 
a friend
gave me the Amp switch made by WB8VGE, which works like a charm. I can't
tell its operation from the full break-in operation with the Omni Vi+. 
(Which is
in Sevierville for a 20 year checkup right now.

Really enjoying the Eagle.

73,
John, K4AVX
