Icom 7300 Receiver Settings For Digital Operation

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

I have used Digital Master 780, Fldigi, WSJT-X, JT65-HF (HB9HQX Edition), and MMTTY to name a few with these receiver settings.

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.

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

    Sometimes I forget this, and I forgot to mention, the notch filter should be turned off too. It’ll create a nice dark patch in the waterfall.

  2. Rich- it says on the Icom USB Driver download that the driver is only for Windows. Is that an issue if you’re running Linux and CQRLOG?? Do you somehow load the driver with Wine? Or do you not need that driver in Linux?

    Thanks again for all your 7300 help!

      1. RIch, how do I turn down the ALC on my Icom 7300 when transmitting on digital modes? The ALC is almost full scale. I also sent you an email on this issue.

          Hi Deryl,

          Great question and I am going to cover that a little more in the next article. Long story short, adjust USB MOD Level in MENU>Settings>Connectors. Also, with this radio, having some ALC deflection is not a bad thing. Just keep within ALC margin. I never let mine get more than 3/4 of the ALC meter. I have a YouTube video about fine tuning digital here: https://youtu.be/VocRqrKc2dQ and then my favorite for adjusting transmit: https://youtu.be/aC8OzLlO_30

          That should do it 🙂

  3. Hi Rich, Just a word of thanks for your so good job with your clear and helpfull postings.
    I use to have a IC-7700 but i’m just surprised with my 7300 as it looks to me that for this money you get nothing and this rig is just amazing.
    Keep on Rich… we thank again and again.
    Warmest greetings from Portugal

  4. Greetings, Rich:
    I am using your “settings” to try and get my 7300 running for W7GJ’s visit to the VK9 islands (09/12)
    Noticed your ref to Irma. I have found Levi Cowan’s audio/vid updates to be most informative. They are at: http://www.tropicaltidbit.com …. many thanks…

  5. Please post a setup file for the SD card along with the U-Tube video and detailed instructions with pictures. A setup file on the SD card is fast, repeatable and more reliable than manual entry.

      Hi Ken,

      Nice to hear from you and thank you for the suggestion. You may be on to something. I have thought about it before and I will look into it again. Thank you! – Rich, K0PIR

  6. I’ve lost the KEY, Rich. Using Digipan 2.0 and it worked for a couple of QSOs and even put it on the SD card but now the only way I can transmit is with the TX Button. I even connected both cables with no help. I’ve tried all variation in the setup, upgraded my firmware, and re-loaded the USB drivers with no help.

      Hi Ken,

      Nice to hear from you. Are you saying you lost PTT? It’s transmitting PSK, but just won’t key the radio? I’m not real familiar with Digipan, but there must be a setting in there for PTT. Try a couple of settings in the PTT settings.

      I hope this helps and thanks for coming by a commenting. Let me know how it goes.

      Rich, K0PIR

  7. No PTT and I’ve tried the CIV cable added also. I’ll try Fldigi, MixW or some others and see if they will key. I don’t want the features of HRD or the expense but it does address the IC-7300 in the setup. Maybe I did push the “TRANSMIT” button for those 2 QSOs but I thought it was all on the USB Cable.

      Hi Ken,

      When there is trouble like that, most of the time it is in the settings. Did you look at the radio under menu>set>connectors, scroll down to the bottom and see what you have set for USB SEND. Mine is set to RTS and I don’t check off RTS in my software when I connect, because it’ll key up the transmitter.

      Fldigi can be quirky too. A simple one to try is WSJT-X. It’s a stand alone program, you don’t need JTAlert or anything else. My 7300 connects just fine with it.
