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.
The Sub band (VFO-B) frequency display will show
the RF Power Output for 3 seconds whenever the [ RF
PWR ] knob is turned.
You may disable this feature (displaying the RF Power
Output) via Menu item "015 diSP LVL IND." See page
117 for details.
The analog PO meter indicates the average power out-
put level. SSB transmit average talk power is normally
10% to 50% of the peak power output. Voice charac-
teristics, microphone qualities, parametric equalizer
and compression settings affect actual talk power out-
put.

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.
