o MAIN BAND INDICATOR [MAIN]
➥ Lights green while the squelch is opened or a sig-
nal is received on the MAIN band; lights red while
transmitting on the MAIN band.
•While transmitting, the indicator also shows ALC con-
dition. Brightness increases more than usual when
the ALC function is activated.
➥ Flashes when an off-frequency signal is received
and the FM center detector is activated. (p. 28)
!0 RF GAIN CONTROL/SQUELCH CONTROL
[RF/SQL] (outer control)
Adjusts the RF gain and squelch threshold level for
the MAIN band. The squelch removes noise output
from the speaker (closed condition) when no signal
is received.
•The squelch is particularly effective for FM. It is also
available for other modes.
•12 to 13 o’clock position is recommended for any setting
of the [RF/SQL] control.
•The squelch threshold position for SSB/CW mode can
be set from 12 or 13 o’clock position in SSB/CW set
mode. (p. 62)
•The control can be set as ‘Auto’ (RF gain control in SSB
and CW; squelch control in FM) or squelch control (RF
gain is fixed at maximum) in set mode as follows. (p. 56)
• When setting as RF gain/squelch control
•When functioning as RF gain control
(Squelch is fixed open; SSB, CW only)
•When functioning as squelch control
(RF gain is fixed at maximum.)
!1 AF CONTROL [AF] (inner control)
Varies the audio output level from the speaker for
the MAIN band.
!2 SUB BAND INDICATOR [SUB]
Lights green while the squelch is opened or a signal
is received on the SUB band; lights red while trans-
mitting in satellite operation.
!3 RF GAIN CONTROL/SQUELCH CONTROL
[RF/SQL] (outer control)
Adjusts the RF gain and squelch threshold level for
the SUB band. The squelch removes noise output
from the speaker (closed condition) when no signal
is received.
