SET MODE OPERATIONS
Squelch Level
Squelch is a function that eliminates the noise when no signals are being received.
Setting the higher squelch level allows you to monitor only stronger signals.
Usually start from level zero (the squelch is open and hear the noise), increasing
the level and when the noise is gone, set just 1 level higher than the current
level. For example the noise is cut at level 3, set the level to 4 and exit.
