Section 6: Programming the Dx-ar-8108 – Manual Supplement

Here is a critical note: The standard user manual typically does not include frequency tables because most countries require a license to broadcast on specific bands. Instead, the manual directs you to a Programming Software (CPS) guide.

However, for licensed amateur radio operators or business band users, here is the general process referenced in the manual’s appendix:

1. Connect: Use a USB programming cable (Kenwood 2-pin style).
2. Software: Install the Dx-ar-8108 CPS (available from your vendor).
3. Read: Turn the radio on, open the software, and click "Read Data."
4. Edit: Enter your frequencies (Rx) and transmit frequencies (Tx). Input CTCSS/DCS values.
5. Write: Click "Write Data." Do not disconnect during this 30-second window.

Vital manual warning: Writing the wrong frequency (e.g., a police band) may be illegal. Only program frequencies your license permits.
