PANEL DESCRIPTION
i RF GAIN CONTROL/SQUELCH CONTROL
[RF/SQL] (outer control)
Adjusts the RF gain and squelch threshold level.
The squelch removes noise output from the
speaker (closed condition) when no signal is re-
ceived.
•The squelch is particularly effective for FM. It is also
available for other modes.
•12 to 1 o’clock position is recommended for any setting
of the [RF/SQL] control.
•The control can be set as ‘Auto’ (RF gain control in SSB,
CW and RTTY; squelch control in AM and FM) or
squelch control (RF gain is fixed at maximum) in set
mode as follows. (p. 69)
•When setting as RF gain/squelch control
While rotating the RF gain control, noise may be
heard. This comes from the DSP unit and does not
indicate an equipment malfunction.
o RF POWER CONTROL [RF POWER]
Continuously varies the RF output power from min-
imum (5 W*) to maximum
(100 W*)
.
*AM mode: 5 W to 40 W
!0 BALANCE CONTROL [BAL] (inner control; p. 31)
Adjusts the audio output balance between main and
sub readout frequencies while in dualwatch.
!1 NOISE REDUCTION LEVEL CONTROL [NR]
(outer control; p. 26)
Adjusts the noise reduction level when the noise re-
duction is in use. Set for maximum readability.
!2 NOISE REDUCTION SWITCH [NR] (p. 26)
Switches the noise reduction ON and OFF.
!3 NOISE BLANKER SWITCH [NB] (p. 27)
➥Switches the noise blanker ON and OFF when
pushed. The noise blanker reduces pulse-type
noise such as that generated by automobile igni-
tion systems. This function cannot be used for
FM, or non-pulse-type noise.
➥Enters the noise blanker level set mode when
pushed for 1 sec.
!4 S/RF METER (p. 36)
Shows the signal strength while receiving. Shows
the relative output power, SWR, ALC or compres-
sion levels while transmitting.
!5 MONITOR SWITCH [MONITOR] (p. 35)
Monitors your transmitted IF signal.
•The CW sidetone functions when [MONITOR] is OFF in
CW mode.
!6 ANTENNA TUNER SWITCH [TUNER] (p. 49)
➥Turns the antenna tuner ON and OFF
(bypass)
when pushed momentarily.
➥Starts to tune the antenna manually when
pushed for 1 sec.
•When the tuner cannot tune the antenna, the tuning
circuit is bypassed automatically after 20 sec.
