KX3 Antenna Tuner & the T1

[Dave KK7SS]

How does the SWR/R/X range of the proposed KX3 AT compare with the T1?
And, just as important, will the KX3 'autotune' with the T1?

Inquiring minds, and all that jazz :)

(Already have a T1 ^_^  )

Thanks..

A little wider (same as the KAT3).

Yes. I'm using a T1 with the K3 on all bands right now, with a 50' off-
center-fed wire, 300-ohm twinlead, and a an Elecraft BL2 balun. Works  
great.

As soon as the KXAT3 is ready, I'll be using that :)

Wayne,

Thank you..

Wayne,

Pardon me if I missed where the details were posted, but I'd like more info on
the "50' off-center-fed wire" antenna you mention. I'm assuming you mean 50'
long, but are you using the traditional 1/3 - 2/3 feedpoint or one of the
other "offsets" that some authors mention?

This sounds like a good possibility for a portable ops "wire in the trees"
antenna. (My primary portable interest is 40/30/20/15 and I'd like to know
how it loads on those bands.)

TNX/73, Al

Entirely random. I'd estimate 45/55, if I were a betting man.

Definitely. In fact I've used this style of antenna with no feedline  
at all: just toss random length wires up into trees in two directions  
and connect them to the two balun inputs.

The 1:1/4:1 switch on the BL2 is also helpful. On bands where the  
antenna presents a difficult impedance, this switch gives the ATU a  
different way to match that is often successful.

73,
Wayne

Wayne, how does your antenna work with the K1 ATU?

Thanks

Quite well. The KAT1 has a smaller matching range than the T1 or KAT2/
KAT3, but it only has to handle 80-15 meters.

I use similar antenna set up as Wayne's for my K2 during portable
operation but use internal KAT2 instead of T1.

The results have been very good and operaton is trouble free.

TNX & 73,

I was playing with NECwin+ and found an interesting antenna.  Later I  
found it had already been invented but it was fascinating to see how the  
numbers worked.  It was an off center fed doublet with the feed point at  
the 3/8 - 5/8 point.  It worked well without a tuner for almost all  
bands.  Play with the numbers and see if you can find a better feedpoint  
for an off center fed wire.

Wayne,

Does 'all bands' include 160m?
