7.3.9 Adjusting receiver squelch
Setting the squelch appropriately based on conditions is important to controlling background radio
noise, as well as maintaining the desired radio system range (the functional distance between
transmitter and receiver antennas). Squelch is basically a noise gate across the receiver’s audio
path that is keyed open by a combination of audio path signal level, and the presence of a unique
combination of tone codes in the received signal. Squelch sets the threshold where the received
signal amplitude will open the noise gate. Signals above the threshold will open the audio path
gate, while signal levels below the threshold will not open the gate.
NOTE: Improperly set squelch negatively affects system range (the distance between transmitter
and receiver).
1
Press the▼ button to scroll down to Squelch on the main menu.
Select by pressing SET to enter the Setup Squelch screen.
2
The display shows the current squelch setting. The numbers on
this scale are arbitrary values from -5 to the left of 0, to +10 to the
right of 0. Higher number values tighten the gate threshold, while
lower number values loosen the gate threshold.
3
Pressing the ▲ button moves the fader bar to the right while
increasing the displayed value in single digit increments thereby
tightening the noise gate, and pressing the ▼ button moves the
fader bar to the left while decreasing the displayed value in single
digit increments thereby loosening the noise gate.
4 Press SET to save and return to main menu.
5
Either scroll ▼down to Exit and press SET, or briefly press SYNC
on the receiver front panel to return to the home screen.
