sEtting thE sQuElch sEnsitiVity
the sensitivity of the squelch to incoming signals can be set
to suit your operating environment. in quiet rural locations
a low setting will allow the weakest signals to be received
while still keeping the radio quiet between transmissions.
in city locations, a higher setting might be needed to ensure
the squelch remains closed when subjected to the higher
interference levels often encountered in high density areas.
the tX3440 has ten (10) preset squelch sensitivity settings
(labelled sql-0 to sql-9) that can be selected using the
menu function. the minimum squelch setting (sql-0) will
open the squelch allowing all signals to be heard. sql-9 is
the maximum setting, requiring very strong signals to open
the squelch. the factory default is sql-3 which generally
provides reliable squelch operation for most applications.
to pre-select the squelch sensitivity
1. select a channel between 1 and 40.
. Press and
hold the mEnu key until the radio beeps.
sql-x will be displayed where x is a number from 1 to 9.
3. Press the or keys increase or decrease the preset
squelch to the desired setting.
4. Press and hold the mEnu key to store the new setting.
sElEcting DuplEx
Duplex operation allows the radio to transmit on a different
frequency to that which is receives. this allows operation
through repeater stations. repeaters automatically
re-transmit your signal over a wider area, providing
greatly increased range.
Duplex operation operates only on channels 1-8. When
duplex is selected on these channels, the radio receives on
that channel but actually transmits 30 channels higher.
