I had a conversation with a friend recently and while talking about the Icom 7300, HRD and DM780 I realized that I haven’t made a good article covering basic receiver settings for digital modes. The settings under “Connectors” have been an issue with some Hams but, also the operational receiver settings, like filter bandwidth, USB data (USB-D), NB, and NR for digital modes. I’ll cover the latter in this post.
The Icom 7300 is an easy radio to use for digital modes because all you need is a USB cable. Set aside your Signalink or whatever you were using with you old radio. The Icom 7300 uses an internal sound card device. Download and install the Windows Icom 7300 USB driver from Icom before attaching the rig to your computer. (I have noticed after my Windows computer updates, the USB driver gets updated too.)
I try to keep my settings the same for all of my software. Whether using RTTY (AFSK), BPSK, JT65, JT9 or FT8, this is a fun and easy digital mode transceiver to operate. The settings in this article will work with all of the major digital modes that I have tried. I won’t delve into CW or RTTY (FSK) in this post.
I can use one or two cables with how I have things setup (more on “Connectors” in the next article) and I can use Windows, Mac or Linux operating systems.
Digital Software, Logging and Rig Control
For rig control and logging I have used Ham Radio Deluxe, ACLog, N1MM Logger+, Log4OM and some others in Windows. On the Mac, RUMLogNG and MacLoggerDX. For Linux, CQRLOG. All of the programs work with basically the same settings.
Save Settings Data to a SD Card
Let’s do this. Before making any changes to your rig, go in and save the settings you have now.
Icom 7300 Receiver Settings For Digital Operation
Here is the next part:
- Press FUNCTION and turn off NR, NB and NOTCH.
- You can elect to turn off AGC as in the video above for digital modes like FT8, JS8Call, JT65 and JT9. For PSK, Contestia, THOR, RTTY (AFSK), etc., I choose to leave my AGC on FAST. Experiment and see what the differences are!

We’ll go deeper into the Icom 7300 menu later. For now you could take a look at N3FJP ACLog, WSJT-X, JTAlert A Powerful Combination.
Thanks for dropping by and I hope you find this useful. I hope to hear you on the air, best 73! – Rich, K0PIR
