[Elecraft] AH-4 Tuner

[Tom Arntzen]

I think icom rigs has an output to the tuner that has a special voltage for
each band. E.g one value for each.
I think it should be possible if you had an interface that recognice K2 band
and set that voltage output to the tuner.
I think I saw the schematics in ARRL handbook some years ago. (or was it a
designe to decode value into auto antennaswitch?)
And you need tune button.

Also I think this could be done manually , but easy to forget to switch
bands.
Bottom line...The tuner needs to know witch band it is tuning.

Someone out there may have the values or you could meassure your own icom
rig to find right value to right band and design a circuit.
But look through ARRL handbook.

If you solve this , let us know.
