Gents,
Using Kenwood's design, you need two things: one for
inside the radio and one for outside...
Inside) You need an IF-10B (not A or C or D) for
inside the radio. It's a kit with an EPROM/board and
some small parts - cap/resistor maybe.
Outside) You need a level converter. I think
Kenwood's number was IF-232. It's a little box (about
the size of a Bencher paddle) that runs on 12VDC.
As far as I know, the stuff is no longer available
retail or directly from Kenwood. However...
A modern approach is PIEXX's - they sell one gizmo for
US$ 89 - all of it goes inside the radio. Some have
complained that it comes with a ribbon cable to 9-pin
D-sub connector that one needs to sneak out under the
940's top cover. Might seem a bit inelegant, but
there's probably no better practical solution short of
tearing the radio apart.
