As we want the IC-7300 to behave like an IC-7700, we need to change this address to 74h the default address for the IC-7700.

The IC-7300 operates on CI-V port (don’t ask!) address 94h by default. It is similar to the normal digital mode interfaces using two (analog) audio cables, only in this case, everything is kept within the digital domain and it only requires one (digital) cable. That’s the one you want to use it “tranports” RX audio via the USB port to your computer (using the virtual line-in) and transports computer generated audio (digitally encoded data) via the USB port to your radio (using the virtual speaker out).

If you check your sound settings, you’ll see that the driver “emulates” a second soundcard with input and output. The second thing that needs to be checked, is a new (virtual!) “audio device” has been added to the system.Ī normal soundcard has loudspeaker output, line input and microphone input. Write the number down somewhere, you’ll need it later. On my system, it’s COM4 but it could be any number. The driver installs a “virtual” serial COM port. Here’s a description of setting up your IC-7300 radio to work with the last freeware version of Ham Radio Deluxe (5.24).įirst of all, download and install this Icom USB driver. Not many HAM radio programs do already support the IC-7300. As far as CAT commands, the IC-7300 seems to be compatible with older radios like the IC-7700.
