Motorola’s VHF/UHF business radio, the GP-68, is operationally identical to Motorola’s amateur (ham) radio, the AP73. Both of the radios have 20 memory channels available for you to program and are representative of Motorola programming. Each memory channel can hold the receive and transmit frequency, and the type of transmit offset. You should get this data from your radio club or a repeater guide.

Step 1

Select the receive frequency you’d like. Enter the receive frequency on the numeric keypad. When all six digits are entered the radio will tune to that frequency.

Step 2

Choose the type of transmit offset and the offset frequency. It can be the same as the receive frequency, have a standard positive or negative offset, or it can be defined by you. Press the button marked “OFS” to toggle between the offsets. They will show up on the screen as plus for standard positive offset, minus for standard negative offset, none for no offset and plus/minus for a user defined transmit frequency.

Step 3

Program a user defined transmit frequency. Press “OFS” until the plus and minus indicators flash. Enter the transmit frequency you’d like to add. Use the numeric keypad. Press the "Toggle Light/Enter" and the "Parameter Transfer" button to add the user defined transmit frequency to the receive frequency.

Step 4

Press the "Toggle Light/Enter" and the "Parameter Transfer" button again until the screen shows "PCh.XX", where "XX" is the last channel selected. Select a channel. It will flash if it isn’t already programmed. Press the "Toggle Light/Enter" and the "Parameter Transfer" button again to store the data to that channel.
