Nav-Data 4-Place Intercom
Thank You The product is exactly what I thought it would be.
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.
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

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.
Yes, you would not need any additional components to communicate with 3 other headsets aside from the 9v battery to power it.
The Nav-Data 4 Place intercom will only work off the 9v battery plus a failsafe feature in the event of dead battery.
To use this with the H10-36 helicopter headset, you would need adapter part number 11-10650.
No, this unit uses a 9V battery as it's power source.
This is a portable intercom. It does not require installation. It is ready to be used out of the box once the headsets are plugged in.
Yes, this will work with Bose A20 headsets outfitted with dual GA plugs.
The pilot isolate switch allows the passengers to speak to each other. The pilot will only hear the radio.
If installed correctly inline you should be able to use a portable PTT switch mounted on the yoke.
