 ALC meter deflection may be caused by excessive
drive power, but also by reflected power detected in
the antenna system. If the impedance presented to
the transceiver is other than 50 Ohms, ALC meter ac-
tion may be observed that is not related to the proper
setting of the [ MIC/SPEED ] knob. Therefore, we
recommend that you make the [ MIC/SPEED ] knob
adjustments into a dummy load or antenna system
presenting impedance very close to 50 Ohms.
 In the SSB mode, you may set the desired power
output via Menu item "177 TX MAX POWER". The
adjustment range is between 5 Watts and 100 Watts.
You should always use the minimum power necessary
to maintain reliable communications.
 When performing "on air" tests (such as the setup of
microphone gain), be sure to check the frequency be-
fore transmitting, to avoid interference to others who
may already be using the frequency.
1. Press the [ MENU ] button to enter the Menu
mode.
2. Rotate the [ CLAR/VFO-B ] knob (or press the
p/q button) to select Menu item "177 TX MAX
POWER".
3. Press the [ SELECT ] button, then rotate the
[ CLAR/VFO-B ] knob (or press the p/q button)
to adjust the desired power output on the Multi-
Display Window.

The value (5 -100) displayed in the Multi-Display
window is a relative percentage of the maximum
TX power available in the selected mode. It is
not the true TX output level.
4. Press the [ SELECT ] button, then press the
[ MENU ] button to save the new setting and exit
to normal operation.

 Four techniques for exercising Transmit/Receive
control are provided on the FT
choose the technique(s) that best suit your operating
needs:
 Pressing the microphone 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
engage the transmitter automatically when you
speak into the microphone. For details of VOX
operation refer to page 72.
