Easy Fldigi – Icom 7610 Fldigi RigCAT .XML File



I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

    Greetings Rich….
    I very carefully put in all the settings on the radio…no problem there…BUT when I followed the instructions for installing the drivers, then connected the usb lead….went to Device Manager and opened ports, I was expecting 2 lines of “Silicon Labs CP210x USB to UART Bridge” each with its specific COM number. Instead I have 2 lines of “CP2102 USB to UART Bridge Controller” (current date)with no port numbers. As a result HRD etc. is not usable. In a word, HELP!

      Hi Peter,

      First, is the USB cable plugged into the correct port on the rear of the IC-7610? There are two ports and you do not want the blue port (USB3.0) that one is for HDSDR. You want the USB2.0 port.

      Did you download the driver from the Icom website?

      The latest driver for the Icom 7610 v1.20 is HERE.

      If you need to you will have to uninstall and install the correct driver. The instructions are HERE.

      I would check the port first.

      Rich, K0PIR

    Great guide! My 7610 now works with RigCAT and a single USB cable. Needed to check the Fldigi Audio tab box for “Modem signal of left and right channels”.
    I use CAT for PTT so no RTS/DTR config needed. Linux seemed to set up the USB-serial connection with its already included driver, so that was easy too.
    Now to get fine-tuning the RigCAT file, and the Fldigi macros. Thank you again!

    Hi John,
    Nice to hear from you and thank you so much for commenting here. Thank you for the additional information and I am glad this helped. Fldigi is one of my favorites. Of course the 7610 is my favorite radio right now. Best to you and yours, 73! Rich, K0PIR

    This is THE source for well-informed clear guidance for 7610. Thank you!
    Now all working, single USB cable, no external interface. 🙂

    The frequency display is 1500Hz wrong? No, but we are generating AFSK, so Tx frequency is Dial + 1500Hz audio. You can do mental 1500 + or – and correct all the log entries, but easier is: Install olctl by GM8JCF ( http://www.g8jcf.uk/olctl/ ). Now fldigi and fllog freq read true and QSLs get confirmed! 🙂 Intended for Olivia, but seems to work on other digital modes too.

    IMHO, this necessary arithmetic should be included in 7610 and/or fldigi?. Perhaps I missed it.

    Hi John,

    Nice to hear from you and thank you so much for the comment.

    Yes I know what you mean about the frequency. In Fldigi go to under the large frequeny display and underneath you will see a couple of drop down lists. Choose USB on the left and 3500 on the right. See if that does it.

    Thanks John, best 73!

      Thank you. It seems that these drop-downs are for 7610’s MODE and bandwidth?
      If 7610’s MODE is set to SSB, and fldigi is being used just for logging and lookups, with fldigi Op Mode set to SSB, the 7610 freq, fldigi large display, and log panel all agree. Good.
      Now, I want to send fldigi-generated PSK31. I set 7610 to USB-D1, fldigi Op Mode to BPSK31, and transmit PSK at 1500Hz +dial frequency, as expected with AFSK. Fldigi’s log freq now correctly shows dial freq+AF tone, while fldigi’s large display and 7610’s dial agree. I can’t get it to misbehave now.

      Magic from Rich: it all works! 🙂

    Thanks so much for the 7600 .xml file. That really helped me out!
