Use with headset and a portable intercom. Cannot use with headset alone.
Installed an icom 200 in my champ with a sigtronics intercom needed this to make it a complete install. Works excellent. The plane had an icom a22 wired in that worked but was a little hard to work with.
Its expensive for what it does. But arrived in 2 days to Canada. Did not charge duty and brokerage. I plugged in 2 DC headsets to the Intercom. It works with both of them. I suppose youd put the PTT button on the stick or wheel. PTT SW comes with a coiled cord. Hard to tyrap them so they are out of the way. I see coiled cords as a hazard. If you had no PTT for the pilot, youd need 2. Expensive. The Sigtronic intercom has both a plug for 12V and a 9V Battery. Intercom Works at low volume with the new 9V battery.
Yes, portable intercoms with PTT ports such as the ITC-2001 are compatible.
Yes, our part number 11-02806 is Sigtronics part number PTT-ICS.
