w RF GAIN CONTROL/ SQUELCH CONTROL
[RF/SQL]
(p. 44)
Rotate to adjust the RF gain and squelch threshold
level.
The squelch removes noise output to the speaker
when no signal is received. (closed condition)
• The squelch is particularly effective for AM and FM, but
also works in other modes.
• The 12 to 1 o'clock position is recommended for the most
effective use of the [RF/SQL] control.
• [RF/SQL] operates as only an RF gain control in SSB,
CW and RTTY (Squelch is fi xed open), or a squelch con-
trol in AM, FM and DV (RF gain is fi xed at maximum sen-
sitivity), when "Auto" is selected as the "RF/SQL Control"
item in the "Function" Set mode. (p. 162)
