Squelch level setting
A squelch eliminates white-noise (the background noise when a signal is
not received).
Higher level settings will keep the squelch "closed" more tightly for
quieter monitoring, but weak signals will not be heard. Lower settings
allow weaker signals to "open" the squelch but noise may also cause it
to open.
• When the S-meter squelch is set to ON, the squelch will be adjusted.
• When the S-meter squelch is set to OFF, the S-meter squelch will be
adjusted.
1.
Press [SQL / REV] key. [SQL / REV] icon
appears on the display and the squelch
level will be shown at the position where
the memory number is displayed.
21 levels, between 0 and 20, are available. "0" is the lowest setting.
2.
By rotating the main dial or by using the [UP]/[DOWN] keys on the
microphone, adjust the squelch to the desired level. To return to
normal use, press [PTT] or any key on the front panel; or if there
are no operations within 5 seconds, the unit will store the setting
and will return to its original status.
