A :
ALC meter deflection may be caused by excessive drive
power, but also by reflected power detected in the an-
tenna system. If the impedance presented to the trans-
ceiver is different from 50 Ohms, ALC meter action
may be observed that is not related to the proper set-
ting of the [ MIC ] (gain) knob. Therefore, we recom-
mend that you make [ MIC ] knob adjustments into a
dummy load or antenna system presenting an imped-
ance very close to 50 Ohms.
Rotate the [ RF PWR ] knob to set the desired power
output. Clockwise rotation of the [ RF PWR ] knob will
increase the power. The adjustment
range is between 10 Watts and 200
Watts, and you should always use the
minimum power necessary for main-
taining reliable communications.

When performing tests (such as the setup of the [ MIC ]
or [ RF PWR ] knobs), be sure to check the frequency
before transmitting, so as to avoid interference to oth-
ers who may already be using the frequency.
Four techniques for exercising Transmit/Receive con-
trol are provided on the FT-2000D, and you may
choose the technique(s) that best suit your operating
needs:
Pressing the microphone's PTT switch will engage
the transmitter.
The rear panel PTT jack may be connected to a
foot switch or other manual switching device in
order to engage the transmitter.
Pressing the front panel [ MOX ] button will lock
the transmitter on. Press the [ MOX ] button again
to return to receive.
The VOX (Voice Operated Xmit) circuit will en-
gage the transmitter automatically when you speak
into the microphone. For details of VOX opera-
tion, see page 78.
