intercom-expander 2->4 Place

[Ingo Wolf]

Hi,

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 are:

- 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.

I just use a 4 place portable. Your options are to
plug it into the copilot position, or just bypass the
onboard intercom entirely and plug all the headsets
into the the portable and then the portable plugs into
the pilot jacks.

Be careful! You may get interference when you transmit or you may get
interference on one of the intcoms from feedback.

Originally, I thought it was due to the sidetone, so I tried turning off
one, then they other. It didn't help. I never did figure out what the
cause was.

Weird. Might be faulty wiring.
