h1. Guide to programming cables

In most cases, the manufacturer of your radio produces the highest quality cable for programming. However, these are usually the most expensive and are not always the most convenient (because of a lack of USB, etc). Third party cables are available for most radios for a fraction of the cost, but quality can be an issue. Several radios use actual RS-232 signalling and thus cables for these radios can be easily home-built.

h3. VHF/UHF Mobile Radios

Nearly all of these radios use an OPC-478 (or similar) cable, which plugs into the speaker jack of the radio. The housing of the 9-pin connector has TTL conversion logic, which can be home-built but it is typically easier to buy one pre-made. Note that some of the mobile D-STAR radios can also use their data connection for programming, which uses RS-232 signalling and requires no conversion hardware. Models that can do this include the IC-2820H, ID-880H, and ID-80.

h3. IC-91AD, IC-92AD, ID-1

These radios operate in "live" mode and require a full-duplex RS-232 serial cable connection. For the IC-91AD, the OPC-1529 cable is used (and can be easily built).

The 92AD uses a moisture-proof custom bayonet connection at the top of the radio, which is only available from Icom (OPC-1799) and only with their RS-92 programming software. Note that the OPC-1797 adapter cable will not allow you to use an OPC-478 programming cable with this radio.

The ID-1 is programmed via its integrated USB connection.
