It would help if you would post the make and model of intercom.

That would be a Sigtronics SPA-400 STO, mounted in a 1976 PA28-161 Warrior.

This intercom is likey a 4 place intercom. The additional two ports can
be added and signed off by a knowledgeable A&P as a minor alteration
with a logbook entry. A few dollars in parts and I cant see how it would
be more than a few hours in labor. The owner or his designee could even
do it if they have the skills, and have it signed off by their regular
mechanic.

The instructions and schematics are at:

....so she couldn't talk to us, she could just listen in on our
conversation. That very nearly became a problem as she got queasy while I
was flying steep turns, stalls and slow flight and she couldn't tell us. ...
I am worried if the one who will be riding in back
gets ill I won't know until too late.

Scott, I would be concerned that you took a non-pilot (ok, I am ASSUMING
the wife is a non-pilot) up on a flight where you were going to be doing
stalls, steep turns and slow flight. These can be quite uncomfortable
for a non-pilot, and they "feel" much different from the back seat
(different sight picture, different position relative to the "fulcrum
point" for the control surfaces).

I am just a low time guy with about 450 hrs or so, but the few times I
have been near airsickness have been in the BACK while someone up front
was doing maneuvers (or was a bad stick in general).


Whenever you take folks up, especially if its a rough day or poor
visibility day, check on them early and often for discomfort, and modify
the flight to the point of aborting if you have to. It sure beats
scrubbing puke out of carpets or washing it out of a flight bag.
