By means of the "ROTARY ENCODER", the squelch threshold is
adjustable:
•
At a setting to 6 (very weak signals are audible with high noise
content; squelch opens at about -105 dBm).
•
At a setting to 26 (only quite strong signals are audible with low
noise content; squelch opens at about -87 dBm). With this
adjustment the receiver sensitivity is significant reduced.
