only)
Transmitter Duty Cycle
Recommended 10% maximum
Modulation Capability*
The modulation shall not be less than 70% and not greater than 99.9% with
a standard modulator signal applied to the transmitter
Carrier Noise Level
Shall be at least 45 dB (S+N)/N

load when the transmitter is modulated at least 70%
Demodulated Audio
Response
Shall be less than 6 dB when the audio input frequency is varied from 350 to
2500 Hz
*When utilizing the configurable microphone gain adjustments, the modulation capability specification can be met with a 70 mVrms to 3.0 Vrms
analog microphone input signal applied to the transmitter. When a digital audio microphone signal is provided by a compatible Garmin audio panel,
the modulation capability specification can be met with a minimum 70 mVrms microphone input signal applied to the audio panel.
