before doing any further work on your transceiver.

HOW TO ACTIVATE AN AUXILIARY OFFSET:
1.
Install NO diode in SIMP, -RPT or +RPT for the channel that gets a non-
standard offset.
2.
Program the AUX matrix row for the desired offset, following our
published instructions.
3.
Connect the channel row to the AUX matrix row by installing a diode as
shown below. The cathode end is soldered to the diode programming
bridge. In this example, Channel 3 uses the auxiliary offset:
4.
You can connect as many of the channel rows as you wish in this
manner, but remember that each would follow the same non-standard
split you have programmed. Only one such split can be programmed in
the AUX matrix row. It may be changed as needed. If more than one
non-standard split is needed, you can either give up a standard split or
devise your own way of switching in what you need.
+TX (+RPT) OFFSETS
+TX offsets are programmed exactly like the Frequency Programming
matrix. For example, for a +600 KHz offset:
N= 600 KHz ÷ 5 KHz = 120
16 K
