3.3.3.8
Carrier Suppression:
In SSB operation the carrier shall be suppressed at least 40
db below one of two equal test tones that are adjusted to deliver
rated PEP by overriding the transmitter gain control circuit under
standard conditions and not less than 25 db below under service
conditions
3.3.3.8.1
Transmitter Gain Control:
Automatic transmittal gain control shall be provided which limits
the average power amplifier plate current to a value which allows
an average RF output of 99 to 157 watts into a properly terminated
load. The time constants of this circuit shall be such as to
allow full PEP output with voice modulation, while at the same
time keeping the average power to the 99 to 157 watt level. This
circuit shall protect the power amplifier and associated power
supplies during tuning cycles and normal operation, and shall
provide the proper carrier level for AM operation.
3.3.3.9
Intermodulation Products:
Odd order intermodulation products of the form 2f1 - f2 or 2f2 - f1 occur-
ring outside the desired passband shall each be at least 30 db
below the RF output level corresponding to one of two equal
test tone. during suppressed carrier operation. The frequencies
of the test tones shall be 900 and 2800 cps and their amplitudes
shall be equal and sufficient to modulate the transmitter to its
peak envelope power rating, when manually overriding the trans-
mitter gain control circuit.
3.3.3.10
Sidetone:
Monitoring of the transmitter output shall be effected via the
receiver audio output channel. The audio signals delivered to
the receiver output while the transmission is in effect shall
be actuated by detecting a small portion of the r-f output.
Under standard conditions the minimum sidetone output from the
receiver shall be 100 w. Under service conditions the sidetone
output shall not be less than 50 mw. The sidetone frequency
response shall not exceed receiving frequency response limits.
Adjustment of the sidetone output from maximum to zero shall be
provided and shall be separate and independent of the adjustment
governing the receiver output during reception.
3.3.3.11
AME Modulation:
Capability:
3.3.3.11.1
With an audio input of less than 0.25 volts rms closed circuit
applied to the microphone input terminals, the equipment shall
be capable of 85% modulation. Audio clipping shall be provided
with the threshold not more than 2 db above 0.25 volts rms at
the microphone terminals.
