[Elecraft] T1 as remote tuner for KX2/KX3?

[Steve Sergeant]

I am developing plans a hut-to-hut skit tour in Canada for next winter.
On this trip, I will want to operate my KX2 inside of metal-roofed
A-frame huts with a 60' feedline (RG-174, RG-58, or 300Ω twinlead?) to
some kind of wire antenna outside. I plan to operate SSB on 40 & 20
meters at a minimum, and 15 & 10m if possible; likely in adverse weather
conditions.

I read the FAQ for the T1 on using it as a remote tuner, which says:

> The T1 is intended for use near the operating position. But with a little effort it could be remoted, and its extremely small size would be beneficial for this purpose. First, the tuner must be placed in a weatherproof container if used outdoors. Second, controlling the tuner remotely requires a shielded control cable back to the operating position; this cable must supply, at minimum, a simple switch closure to wake up the tuner. It’s also possible to create your own band-data interface from the rig to the ATU, as explained in the T1 Owner’s Manual. Finally, you’ll need an SWR bridge at the operating position since you won’t be able to see the LEDs on the T1.

I can see that the KX2 manual and the T1 manual give a lot of
information about control signals and such. But before I take the time
to try to engineer something or hack something, I'll ask the obvious
question:

Has anybody out there done this?

Follow-up questions to anybody who has:

Can you describe your set-up?

Have any of you found a way to use the KXIO2 and either the PFn or some
other feature to control the T1 from the KX2 through a separate
3-conductor cable?
