My flight instructor carries two pairs of splitter cables. I wish I knew
how to wire them because they look quite simple. He says that he bought
them at a pilot shop for about 50 bucks. Essentially you plug one into the
cockpit, and that splits into two. If I run across them for sale on the net
I will respond back.

I was looking at these, in anticipation of getting my ticket soon (I
hope!). The prices seem to be all over the board. Many seem to have an add
on module for use with 4 passengers.

I certainly don't know how to design electronic stuff, although I can read
a schematic and build something from one, so how hard is it to build your
own portable setup for a renter? a battery or running off the planes 12V
socket to boost the signal somehow (I guess-many units seem to require one
or the other). A bunch of jacks for the headsets, a couple of plugs for
going into the pilots com jacks. Switches for all/pilot-copilot
isolate/pilot isolate (sounds like a mess of wiring in their), maybe
auxilary inputs for CD players and cell phones.
Hmmm...how do you wire in the copilots mike when the plane has built in
PTT switches?

Starting to sound more complicated than I thought.
