ADVANCED OPERATION

Frequency Offset Defaults

When you select a frequency, the HTX-242 defaults to the following
frequency offsets if auto duplex is turned on:
Receive Frequency
Below 144.600 MHz
144.600 to 144.905 MHz
144.910 to 145.205 MHz
145.210 to 145.505 MHz
145.510 to 146.005 MHz
146.010 to 146.375 MHz
146.380 to 146.605 MHz
146.610 to 146.995 MHz
147.000 to 147.395 MHz
147.400 to 147.595 MHz
147.600 to 147.995 MHz
148.000 MHz and above
The default offset is 600 kHz. For example, if you tune to receive
146.940 MHz, the HTX-242 automatically transmits at 146.340
MHz (600 kHz less than 146.940).
!
Note: Outside these ranges, the HTX-242 operates with no offset.

Turning Auto Duplex On and Off

The HTX-242 can automatically select the correct duplex offset for
frequencies normally assigned to repeaters and selects no offset
(simplex) for other frequencies. Follow these steps to turn this
option on or off.
