The FPGA reduces the need for complex circuitry and simplifies the RF path. A simplified RF path is vital to low noise, clear signals, and better weak signal reception. Third Order Intercept Point (IP3) is greatly improved and allows the operator to more easily copy weak signals that is often covered up by a strong, adjacent signal. The use of an analog to digital converter (AD) reduces signal distortion and in some cases eliminate it. 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.DX operators will appreciate the ability to copy weak signals others won't be able to hear.Ī true real-time spectrum scope. 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. The driver installs a “virtual” serial COM port. On my system, it’s COM4 but it could be any number. Write the number down somewhere, you’ll need it later.
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. If you check your sound settings, you’ll see that the driver “emulates” a second soundcard with input and output. 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). 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. The IC-7300 operates on CI-V port (don’t ask!) address 94h by default. 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.
Note that ham radio Deluxe supports changing the CI-V port to any address you want, but while may other ham radio programs do not have this option and use the default address for the selected radio (e.g.
