I need to make a correction.
I do not have a Sigtronics SPA400 Intercom. It is a PS Engineering PM500EX.
It is listed for experimental aircraft, but It WILL work fine in a certified aircraft. This is a 4 Channel/4 place panel mounted intercom.
Lyle has not full committed so if anyone else is interested, let me know. In a box and ready to ship.
