Why not ground the antenna and feed it as a Unipole? Most AM BC
stations are doing that these days. They also use a remote tuner,
although it is usually a fixed network as they only use one frequency.
That way the reflected power on the line is nil.

Chris,
If all else fails, cheat. Probably the very simplest thing you can
do is mount an 17 meter element in parallel to the 80 meter element. It
will be cheaper and no less efficient.

And it is now fixed. Sorry about that! Thanks for the heads up everyone.
No change to KPA500 product status. Still for sale and selling well. :-)

Have you tried adding some additional length to the 600 ohm feedline? I
originally couldn't perfectly match 30 meters with the Johnson Matchbox and
added about 15 or 18 feet IIRC. That brought 30m into range and didn't mess

Thanks, Don,
Yes I understand the basics - the doublet is not typically used in a
"matched" configuration, thus the need for the tuner. If I understand
correctly, it can present from very low to very high impedances to the
tuner. I will try a 1:1 and/or adding some wire length. Also, as I

Chris,
Try a 1:1 balun instead of the 4:1. You are matching the impedance seen
at the shack end of the feedline, and that can vary from very low to
very high.
The impedance you have to match is NOT the characteristic impedance of
the feedline. The 600 ohm line simply acts as an impedance tra

Thanks, Bob. I'll do just that when I get a chance. And I might just try
the 1:1 also! I have an Array Solutions analyzer, been meaning to scan it
to see exactly what the tuner sees. All of this requires a ladder and some
creative juggling of tools/laptop etc. ;)

Chris;
Add or remove about 6 ft of the open wire line. See if this helps the
17M issue.
I personally don't like the idea of using a 4:1 balun and much prefer a
1:1 current balun. With the 4:1, without measuring the Z on the coax
side, it may be the Z presented to the tuner is very low and

Does it have any upgrades, such as the new Synth and DSP module?
I've just seen a K3 + P3 go for $2670 on eBay UK.

Yes, is very sad.
I am very sorry that Bill left us.
I proudly own his second Elecrat K2 #6254, he built that K2 in the 2007

enough at 1500w at 144-MHz to "barely" discern by touch. Since room
