question: on the ORIGINAL IC706 is the TUNER/CALL SWITCH active or do I need
to switch something under the hood to get it to work? I am using an ICAH4
tuner (80m-6m) and it does not work with the original 706 (same plug and
wiring), but works OK with the 706MK2g!

John-

I think it should work but my 706 is kaput, so I can't try it.

When I bought the IC 7000, the old IC 180 tuner wouldn't work with it
until I did a reset with the tuner attached. I don't recall how, but it
may be mentioned in the manual.
