K2/KAT100-1

I'm just wrapping up the build of the KAT100 antenna tuner (I was in need of
a solder fix) and a thought occurred to me. Has anyone considered an
external circuit that would allow the KAT100 to be used with HF transceivers
other than the K2? The K2-KAT100 interface is a great feature and very well
thought out. But the KAT100 is such a dynamic accessory that I'd love to be
able to take it with me when I travel with my IC-706mkIIG and other rigs
that lack internal tuners. (My IC-706 is one of my "knock around" rigs that
I take places that I would rather not take the K2).

I assume this circuit would require more than just a momentary-action "Tune"
button in a box. Any ideas? Does anyone think this can be done? It might
even increase the market for the KAT100.

73,

Terry, W0FM

Terry,

Sorry, but the KAT100 needs the K2 AUXBUS signal to tune, change
settings per band/per antenna, etc.

Re: K2/KAT100-1

Well, Don, I knew the brains were in the K2 but was thinking of the minimum
extra stuff necessary to make the KAT100 work like many of the other
commercial auto tuners that are not rig specific. I guess that would mean
duplicating the K2 AUXBUS circuitry in an outboard box. I'm thinking you
are saying it's not a realistic idea.

OK< I'll retreat to my kitchen remodel. That's still pretty straight
forward. ;o)

Re: K2/KAT100-1

Terry,

A high power version of the Elecraft T1 would do that job, but I would
think the Elecraft portion of that market would be small, there are
several auto-tuners for the 150 to 200 watt range already in the
marketplace.

Enjoy the remodeling task.
