Next to COM Port choose the CI-V port (mine is COM6 and you can look under Windows device manager to find the correct Port, look for Prolific USB-to-Serial Comm Port).

Next to Radio choose IC-7700 (IC-7300 if using the paid or trial version).

Step five, start Ham Radio Deluxe and on the Rig Connection Screen choose the New tab. The paid and trial version has the IC-7300 listed under radios, where-as in the free version we will choose the IC-7700 and alter the CI-V address. For this tutorial we will be using the free version. Step four, if you don’t already have it, download and install HRD. I have included a couple of extra settings that will help later on when using PSK31, RTTY (FSK) and CW keying. Set the following menu items under MENU>SET>Connectors. These are the changes, leave everything else to default settings. Step three, setup the Icom 7300 using the radio’s menu. Do not connect the USB cable until you have downloaded and installed the driver.

Step one, if you haven’t already, download and install the latest USB driver from Icom for your Icom IC-7300. If you just want to use a USB Cable with HRD and operate some PSK31 or RTTY (AFSK), take a look at this video. I have found this to be the easiest, because later on I added cw keying and RTTY (FSK) to the mix. Use the CI-V for rig control and the USB for the soundcard. One is the USB cable connected to the radios USB port and the other is a CI-V cable connected to the radios CI-V port. UPDATE: New article using the Icom 7300 with Ham Radio Deluxe v6.5 Icom 7300 Ham Radio Deluxe Setup So if you’re interested in the “swiss army knife of ham radio” and using it with the Icom 7300, you’re in the right place.
