Introduction 1-6 X-2 Technical Service Manual
Publication No: 15-02047
1.6.3 Transmitter Specifications
Type
All solid state.
Power Output
100 W PEP ± 0.5 dB may be internally set to
any output between 125 and 25 W PEP.
CW or single tone approx. 60% of PEP.
(Average ALC control).
Duty Cycle
100% normal speech.
Supply Current
2-tone/CW 8 to 12 A
Average speech 6 A
Average speech for battery life calculations.
Protection
Safe under all load conditions by limiting
reflected power to 10 W PEP and limiting PA
transistor collector voltage swing.
Thermal protection against excessive heatsink
temperature.
AF Response
Overall response of microphone and transmitter
rises approximately 6 dB/octave 300-2700 Hz.
Electrical input -6(8) dB, 300-2700 Hz.
Ripple 2(4) dB pp, 500-2500 Hz.
Spurious and
Harmonic Emissions
55(48) dB below PEP.
Carrier Suppression
60(50) dB below PEP.
Unwanted Sideband
50(45) dB below PEP (400 Hz).
70(65) dB below PEP (1 kHz).
Intermodulation
(2 tone test)
100 W 30(26) dB below each tone.
36(32) dB below PEP.
125 W 27(26) dB below each tone.
33(32) 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.
Residual Noise
65(55) dB below PEP of selected channel.
Microphone
Dynamic type with push-to-talk switch fitted in
the case.
