Ingo,

Does anybody know portable expanders to
plug 4 intercoms into an builtin 2 place-Intercom.
I sometimes rent aircrafts having only a two-place
Interkom but would like also to speak with the
passengers.


The solution is to plug a portable 4-place-intercom into the pilot side
of the built-in intercom and plug all headsets into the portable. The
disadvantages a

- A built-in PTT on the copilot side will not work
- The built-in PTT on the pilot side will work, but everybody speaking
on the intercom circuit at the time will get transmitted.
