Squelch Settings
Each of the four (4) receivers of the base
station has four (4)
adjustable squelch levels. These levels are equivalent to a
SINAD level to open squelch for a receiver. The higher the
squelch level number, the quieter the receiver is before it
squelches; however, the RF range is slightly less than a receiver
with a lower number.
00 = OPEN (for testing only, do not use)
01 = 12dB SINAD
02 = 20dB SINAD (Default)
03 = 24dB SINAD
CAUTION: Do not use Squelch Setting 00! A squelch level of
00 turns off all squelch gating. This can allow loud
white noise into the audio of a base station if no
transmitter is on the RF frequency or the portable
select button is on. This setting is for test purposes
only.
