RECEIVE AND TRANSMIT

Function for transmit

ï Output power and microphone gain
• Setting output power
q Push [SET] for 1 sec. to select quick set mode.
w Push [∫ UP]/[√ DN] one or more times to select
"RF Power".
e Rotate the main dial to select the desired output.
• Output power is displayed in 101 steps (L, 1–99 and H)
but is continuously selectable.
• Available power
SSB/CW/RTTY:
AM:
*Carrier power
• Setting microphone gain
Microphone gain must be adjusted properly so that
your signal does not distort when transmitted.
q Select SSB or another phone mode.
w Push [SET] for 1 sec. to enter the quick set mode.
e Push [∫ UP]/[√ DN] one or more times to select
"MIC GAIN".
r When speaking into the microphone adjust the mic
gain so that the ALC meter does not peak past the
ALC zone.
t Push [SET] to exit quick set mode.
ï Meter function
The bar meter in the function display acts as an S-
meter (for relative signal strength) during receive and
can be selected for one of three functions during
transmit.
• Push [SET] one or more times to select the PO, ALC
and SWR meter mode.

INDICATION
Po
Indicates the relative RF output power.
Indicates the ALC level. When the
meter movement shows the input signal
level exceeds the allowable level, the
ALC
ALC limits the RF power. In such cases,
reduce the microphone gain (see
above).
Indicates the SWR over the transmis-
SWR
sion line.
Maximum output
power is selected.
Microphone gain is
set to 50.
