>>> Enter Next Frequency for Programming:

Enter Receiver Frequency as 6 digits with NO decimal!

For example: 146.52 MHz. = 146520. Enter here >>> ?

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

32 K
