DETAILED MENU ITEMS DESCRIPTION
TX/RX GROUP
Squelch adjustment (SQL)
The squelch system allows you to mute the background noise when no signal is
being received, which makes “standby” operation more pleasant. It also
significantly reduces battery current consumption.
The squelch level can be adjusted from level 0 to 9. Level 0 is the lowest with
squelch always opened, level 9 is the highest.
When the squelch level is too high, if signal is too weak, it may not be received
efficiently. When the squelch level is too low, you may suffer from noise
interference.
The default setting is level 5.
