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. 99)
•When setting as RF gain/squelch control
•When functioning as RF gain control
(Squelch is fixed open; SSB, CW, RTTY only)
•When functioning as squelch control
(RF gain is fixed at maximum.)
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 S/RF METER (p. 31)
Shows the signal strength while receiving. Shows
the relative output power, SWR, ALC or compres-
sion levels while transmitting.
!1 MONITOR SWITCH [MONITOR] (p. 70)
Monitors your transmitted IF signal.
•The CW side tone functions regardless of the [MONI-
TOR] switch setting in CW mode.
•The [MONITOR] indicator in this switch lights green
when the function is activated.
!2 ANTENNA TUNER SWITCH [TUNER] (p. 89)
➥ Turns the internal antenna tuner ON and OFF
(bypass)
when pushed momentarily.
➥ Tunes the antenna manually when pushed for 1
sec.
•The [TUNER] indicator in this switch lights red when
the function is activated or blinks during manual tun-
ing.
•When the tuner cannot tune the antenna, the tuning
circuit is bypassed automatically after 20 sec.
