■ Functions for receive
DD
Volume setting
➥ Rotate [AF] control for the specified operating band
(MAIN or SUB) to output a suitable audio level.
DD
Squelch setting
The squelch removes noise output from the speaker
(closed position) when no signal is received. The
squelch is particularly effective for FM. It is also avail-
able for other modes.
With the default setting, noise squelch and S-meter
squelch in FM, RF gain and S-meter squelch in
SSB/CW mode operation are assigned to [RF/SQL]
control. The assignment can be changed in the gen-
eral set mode. (p. 56)
• When operating in FM
q Rotate [RF/SQL] fully counterclockwise.
w Rotate [RF/SQL] clockwise to the position where
the noise just disappears.
• MAIN/SUB band indicator also goes OFF.
By rotating [RF/SQL] to a deeper position (clockwise),
the S-meter will move and the S-meter squelch func-
tion will be activated. When the S-meter squelch is ac-
tivated, weak signals, weaker than the S-meter
squelch set level, are ignored.
• When operating in SSB/CW
q Rotate [RF/SQL] fully counterclockwise.
w Rotate [RF/SQL] clockwise to the position where
the maximum RF gain (S-meter bar disappears),
MAIN/SUB band indicator goes OFF, and floor
noise disappears.
•With the default setting, the squelch opens at 12 o’clock
position, however, the squelch threshold level can be set
to 13 o’clock (1 o’clock) position in the SSB/CW set
mode. (p. 62)
•When rotating [RF/SQL] counterclockwise, RF gain de-
creases (lower sensitivity) and the S-meter bar appears
to indicate the receivable RF signal level.
