NGT—Overview and specifications
40 NGT Transceiver System Technical Service Manual
A/F response Overall response of microphone and transmitter rises approximately
6 dB/octave 300 to 2700 Hz
Electrical input: −8 [–6] dB 300 to 2800 Hz
Ripple: 4 [2] dB p–p 500 to 2700 Hz
Spurious and harmonic
emissions
Better than 60 [65] dB below PEP
Carrier suppression 50 [60] dB below PEP
Unwanted sideband 55 [70] dB below PEP (400 Hz)
65 [70] dB below PEP (1 kHz)
Intermodulation
(Two-tone test)
100 W: 26 [30] dB below each tone 32 [36] dB below PEP
125 W: 26 [27] dB below each tone 32 [33] dB below PEP
ALC A 10 dB increase in signal input above compression threshold produces less
than 0.5 dB increase in power output
Maximum ALC range greater than 30 dB
ALC attack time approximately 1 ms
Microphone Electret Condenser type
