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!

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.

The Tuner button needs a signal on the 4 pin Molex connector before it will
do anything. The connector is looking for the tuner to tell the rig it is
tuned. There was a circuit on the net a while back that could fool the rig
into thinking it has a tuner attached, I think it involved one transistor,
but it seems like it disappeared from the net a few years back. Perhaps
there is another.
