A few years ago I purchased a four place intercom (Nav-Data) from Aircraft Spruce. Recently the toggle switch appears to have started failing. Something in the switch is causing the PPT to stay on even when I dont have the PPT pressed. It happens when I toggle over to radio (pilot). However, the co-pilot cant here me when its in the middle. I purchased the intercom and push-to-talk (also a Nav-Data product last month) from AirCraft Spruce. I jammed up the airways at the Prince George airport and got a serious lecture from air traffic controller. They thought my PPT was stuck, but I know its the toggle switch (or something associated with it) is failing when on the radio side. I had to unplug it to stop it from transmitting.

Not worth the money. Terribly noisy, can barely understand instructor, also distorts radio

I purchased this intercom about 6 years ago. It has worked great until recently when the wire to the battery broke off. I repaired the wire and it works great again.
Ответ:No, you cannot run two intercoms and have them work together. A portable intercom is intended to override the panel mount intercom. Your best bet is to buy a four place intercom and have everyone in the cabin plug into it and plug the intercom into the pilot side panel jacks.
