Dimensions, weight, and mounting requirements. Key Line: Pin 11

When is externally grounded through a dedicated cockpit switch while the main transmitter key line remains open, the microphone audio bypasses the transmitter's internal modulator. The internal circuitry routes and amplifies the signal directly through the 50 mW audio amplifier to create an integrated two-place cabin intercom. Both microphones used in this setup must be the exact same model to prevent unexpected audio volume shifting. 3. Antenna Installation and RF Coaxial Connections

An intercom mode is activated by grounding Pin 12 through an external switch while the mike key line is open, allowing mike audio to bypass the modulator and reach the headphones.
