COM Transmitter Specifications
Microphone input: Two inputs, standard carbon or dynamic mic with integrated preamp. The GTR 200 provides a 150 Ω AC input impedance and supplies the microphone with an 11 V bias through 470 Ω +/- 5 percent
Modulation capability: 85 percent with 250 to 2500 mVRMS microphone input at 1000 Hz
Modulation: AM double sided emission designator, 6K00A3E (118-136.975 MHz)
Frequency range: 118.000 to 136.975 MHz, 25 kHz channel spacing
Frequency tolerance: +/-5 ppm from -20°C to +55°C
Output power: 10 W carrier minimum
Duty cycle: 20 percent
Carrier noise level: At least 35 dB (SNR)
Stuck mic time-out: 35 seconds time-out, reverts to receive
Demodulated audio distortion: Less than 25 percent distortion when the transmitter is at 85 percent modulation at 350 to 2500 Hz
