Transmitter (Tx) Controls and Indicators
4 The transmitter’s controls and indicators (see Fig. 4-1) comprise a
SET PWR control, PTT switch and the four monitor switches LINE, FWD,
RFL and MOD. It should be noted that only one monitor function can be
selected at any one time; to deselect a selected function, press the
selected function switch or select the other function or press the RESET
switch.
SET PWR
5 The maximum output power from the transmitter is 40 W (AM) or
60 W (FM). The set power control allows a reduction of output power
between 0 and 10 dB. Note that when the radio is connected to a PAE
3640 power amplifier, the FM output is reduced to 40 W.
PTT
6 A momentary action press-to-operate switch: When the switch is
pressed, the transmitter becomes keyed, and the adjacent indicator lights.
LINE
7 Two-position push-to-select (push again to deselect) line monitor
switch. When selected, the adjacent indicator is lit and the front panel
monitor display shows the transmitter’s line input level (in dBm).
FWD
8 Two-position push-to-select (push again to deselect) forward power monitor switch. When
selected, the adjacent indicator is lit and the front panel monitor display shows the transmitter’s forward
output power (in watts).
RFL
9 Two-position push-to-select (push again to deselect) reflected power monitor switch. When
selected, the adjacent indicator is lit and the front panel monitor display shows the transmitter’s reflected
output power (in watts).
MOD
10 Two-position push-to-select (push again to deselect) modulation depth monitor switch. When
selected, the adjacent indicator is lit and the front panel monitor display shows the transmitter’s
modulation depth (as a % when AM is selected, or in kHz when FM is selected).
