Icom 7610 Rig Control N3FJP Amateur Contact Log and Fldigi


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.

      Hi Brian,

      Thank you for commenting and nice to hear from you.

      That’s what I’ve heard, but I don’t believe it’ll be much longer for them to be delivering in the UK.

      You can benefit from the mistakes and then corrections we’ve made, hi hi.

      If you use an amp, remember to set the TX delay. I use an older Ameritron 811 and have the TX Delay set to 20ms.

      HNY and let us know when you get it.

    Just what I was looking for Rich! Thanks! One question though, this works in USB-D mode. What about making it work in RTTY mode on the rig? I was making contacts in RTTY with FLDIGI but in USB-D, not RTTY on the rig. Thanks again, N8DNG

    • K0PIR says:

      Hi Steve,

      Nice to hear from you and thank you for commenting and the question.

      We can accomplish RTTY (FSK) on the rig with a keyboard, but I haven’t attempted that yet. Someday!

      Fldigi won’t operate in FSK mode, just AFSK.

      For RTTY (FSK) with a computer a good solution is MMTTY and many use N1MM Logger Plus as a log for it. That last part is not necessary though. We can use MMTTY as a stanalone and import it’s log into our favorite logging program.

      See: http://www.k0pir.us/icom-7610-n1mm-rtty-fsk/

      That last link I use two cables with the Icom 7300, but it is unnecessary with the Icom 7610. The 7610 has two virtual COM ports. That first link explains it.

      HNY and thank you again.

      Let me know how it goes.

    My Question, what cables will I need to go from the computer to the IC-7610 so I can do JT modes, FLdigi etc?

    I do not see this mentioned in the page here yet.

    I have no speakers hooked to my computer, so video is of no help;
    text works as I can still see that with my eyes at this time.

    Thanks 73 de K2HAT 🙂

    • K0PIR says:

      Hi Lee,

      Thank you for commenting and I understand. All you need is the USB 2.0 cable. We’re not using the USB 3.0 high speed port yet. Install the driver from Icom first, then attach the cable.

      You’ll see two COM ports in your computers Device Manager. I have a video explaining those, but long story short, choose the first Silicon Labs CP210x you see in Device Manager for the Com Port in the software. For sound you’ll be using the USB Audio CODEC for input and output in the software.

      Let me know how it goes.

    Nice video on interfacing N3FJP and FLDIGI. The 7610 looks like a nice rig, but it will look nicer to me when the price comes down and the many bugs are worked out. Meanwhile, I still like my 7600.

    I also use N3FJP and it is an excellent logging program. Do you know if the N3FJP/FLDIGI combo works as well on the 7600?

    Thanks and 73

      Hi Gregg,

      Thank you and it’s nice to hear from you.

      The 7600 is a fine transceiver and I have a friend who loves his. He won’t be giving it up anytime soon.

      I am sure it would work the same with the 7600. It just a matter of setting up N3FJP and Fldigi to talk to each other and it works very nice.

      Best 73,

    Great Video. Trying to get the 7610 to transmit in FLDigi. I am using AALog for logging but maybe it is time to switch. Love the way ACLog interfaces to FLDigi. Wonder if AALog would do the same? Thanks for another great video

    • K0PIR says:

      Hi Dennis,

      I will e-mail you some screen shots of my Fldigi setup. It can be a pain sometimes, but once it’s going it works FB.

      For Rig Control and PTT I am using RigCAT.

      I haven’t used ACLog with Fldigi a whole lot, but I really like N3FJP’s software and he has excellent support on YaHoo forums.

      Thank you for the comment and it’s nice to see you here.

    Thanks Rich

    Look forward to the slide.

    Thanks for your help


  7. Joe Colson W4LBY says:

    Any plans for a video on connecting the Icom 7610 to a lan system for remote operation?

    • K0PIR says:

      Hi Joe,

      Nice to hear from you and yes, I am working with RS-BA1 now. It’s working! I’ve made numerous contacts with it and my laptop. It works very well. I just have to put something together. I think I’ll start with the basic install, conf of the radio and then conf of the RS-BA1 software. It may be a bit long, but I want to present enough information to be helpful. Thanks for the interest! 73, Rich, K0PIR

    Cheers all, just getting new 7610 up and running with Flrig and Fldigi.
    changed CV address to 98, setup per screens above, but new radio FW only allows 8ms delay on tx however I have reed/vacuum relay QSK that works to 3.4ms no problem.
    I tried the 7300 setting with com6 (first port), 115200 baud matching radio, tried different combinations of RTS/DTR. with 7300 it does initialize, tune works, but it and TX button on Flrig leave transmitter keyed.

    What did we miss? 73’s K7BIT

    • K0PIR says:

      Hi John,

      Nice to hear from you and thank you for commenting.

      I don’t use Flrig much but maybe it is RTS/DTR. In the radio go to Menu>Set>Connectors and change the USB Send to OFF.

      See if that works.

    Is it possible to get Fldigi to send cw on the 7610 with the keyboard? NOT using SSb audio?

    • K0PIR says:

      Hi Chuck,

      Nice to hear from you and that’s a very good question. At one time I was told that it was not possible, but if we use a separate port for CW I don’t see why not. It’s something to look at again.

      Thank you and when I get back on my 7610 I’ll try it.

      Rich, K0PIR

    • K0PIR says:

      I looked at it again and the radio needs to be in USB-D1 mode for it to send, so I guess not.

      If you are using N3FJP you can send CW from it.

      Rich, K0PIR

  10. Carl A Horvath says:

    Hi Rich, I had to get another computer, and re-install software.

    Now I can’t get the N3FJP and the Fldig to talk again.

    In the config window for the fldigi this is all I see


    Any ideas?

    Yes, the N3FJP does control the radio and read out the correct frequency.

      Hi Carl,

      I had a problem with my Icom 7610 and N3FJP. I used Icom 2 in N3FJP software. It worked, just set the CI-V address in N3FJP too. Is yours connecting to the radio?

      I am not sure what you are seeing. Using Fldigi I sometimes had to restart the PC before it would see it.
