Icom 7610 Rig Control N3FJP Amateur Contact Log and Fldigi

Icom 7610 rig control problems? Having trouble finding software for the Icom 7610? If you are a fan of N3FJP software and Fldigi then this is for you. This works for the Icom IC-7300 too. Amateur Contact Log is easy to configure for the Icom 7610 and Fldigi integrates with it beautifully! Fldigi logs right into AC Log. Wow, what a great combo!

As of the writing of this post, Icom 7610 owners have to look at rig control alternatives for the Icom IC-7610. Currently Flrig, HamLib and RigCAT do not have files for the Icom 7610.

Icom 7610 Rig Control Using N3FJP Amateur Contact Log

It’s easy to configure N3FJP’s Amateur Contact Log for the Icom IC-7610. Especially if you are replacing a previous radio. Just change the CI-V address in ACLog under Rig Interface to 98 for the IC-7610. Change it to 94 for the IC-7300.

For Icom 7610 rig control choose the correct Com Port, Baud Rate and change the Command to Read Frequency CI-V address to 98, Don’t forget the other side, Command To Read Mode. It needs to be 98 too. Try it.

For Fldigi to communicate and follow AC Log, enable the Application Program Interface (API) Server in ACLog.

Fldigi Configuration with N3FJP

Open Fldigi and go to the Fldigi configuration window. Enable a couple of things and you’re off and running. See the video below for more.

Icom 7610 Connected to ACLog with Fldigi

Since the Icom 7610 is not an entry level radio, I am guessing you are already familiar with how ACLog and Fldigi operate. If you are not familiar, see the video below. I’ll go into a little more detail.

When making a contact using Fldigi, Fldigi will save the QSO to ACLog automatically. They intergrate perfectly.

Tune the Icom 7610 to change frequency and both programs follow.

Log a PSK31 (or any digital mode) and the contact/QSO information correctly transfers to AC Log. Note: You’ll have to enter your correct power in ACLog, but everything else will be fine.

Have you been using Fldigi with the 7610? What are you using to connect to the radio?

Captures from my IC-7610

The first row and bottom 2 photos on the left are important for this application. Note: The capture on the top far right (USB SEND/KEYING), I have set these so I can use my USB cable for RTTY (FSK). This will not be necessary for you in this application. It won’t hurt anything though.

IMPORTANT: The bottom 2 on the right (TX DELAY & CW-KEY SET) are needed if you run an amplifier and CW QSK.

Push Menu>SET>Connectors for the first 6 captures (top row and two left captures on the bottom row).

Push Menu>SET>FUNCTION to set the TX Delay.

To change the CW Rise Time. Go into CW Mode, push Menu, KEYER and EDIT/SET. Tap CW-KEY SET and increase the Rise Time.

Unnecessary until you want to operate thru a LAN.

I use this for RTTY (FSK) It works for this application too.

      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.

  2. 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

      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.

      Rich, K0PIR

  3. 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 🙂

      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.

  4. 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,
      Rich, K0PIR
