NEW Fldigi Real CW via DTR Keying

This is new to me, Fldigi real cw via DTR keying. No more sending SSB CW with Fldigi. This feature came out a little while back, but with everything going on I missed it. I am using a CW USB Keying Cable, but there are other options. A good informational source for Fldigi is the WinFldigi forum on Groups.io.

Fldigi Download

  • Get the latest Fldigi here. It is available for Windows, Mac and Linux. I hear it works great on all three platforms.

Fldigi Real CW

  • Put the radio in CW mode and you can use your CW filters. The Icom 7610 has APF.
  • See my Icom 7610 and Icom 7300 Screen Capture Pages for internal menu settings on these radios.

I only noticed this Fldigi update when I was preparing a video and article on MacLoggerDX Fldigi AutoLog Script with PTT App.

Just for kicks I thought I would go back and see how Fldigi real CW works with ACLog on my Windows PC. I am running Windows 10 Pro.

Fldigi Configuration For ACLog

Right now I am using a CW interface, but have tried it different ways and it works great. I have not had any trouble keying at 12-18wpm. Many users have reported much, much higher speeds.

  • Disable CW keying in ACLog. You may be able to enable it later, but get Fldigi sending real CW first.
  • In Fldigi go to Fldigi configuration>Logging>N3FJP logs and enable connect. See second image below.

Fldigi Configuration for Icom 7610 Using RigCAT

So if you just want to use Fldigi in a stand alone operation you can use RigCAT for rig control in Fldigi. See first image below.

  • For RigCAT we need a .xml file for the rig you are using. There is an .xml for the Icom 7300. However, Fldigi does not come with a .xml file for the Icom 7610, so I edited a .xml and it works FB. You can download my 7610.xml here. Download the 7300.xml from Sourceforge here.

In Hamlib there is a Icom 7610, but it is untested and I have not used it yet.

  • With the Icom 7610 we get two virtual serial ports. Com4 is my CI-V serial port and I decided to try Com5 which is used for DTR keying. See second image below

More Configurations

There are more ways to configure this.

  • For Icom transceivers: Use a CI-V cable for rig control in Fldigi (RigCAT) and then a CW interface for DTR keying. This configuration leaves your USB cable open for rig control in your logging program.
  • “Unlink from [REMOTE]” must be used in the Icom menu.

Thank You

Since my stroke I am alternating between the software and my paddle, decoding what I can with the help of notepad. It is my form of therapy, hi hi. By practicing I hope too improve my memory, fist and typing.

I hope all is well where you are.

Coming Soon – I will have a video, article and pictures of my campers Hi-Q mobile antenna installation, the updated solar installation and an update on my Tarheel 200A mobile antenna.

If you have any questions, comments or solutions, please comment below. I prefer the comment section here or in YouTube over e-mail because your comments and questions will help others as well.

73,

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.

  1. Thank you so much for your informative videos, Rich.
    I’m a user of the 7610 and 9700. I hope you will buy a 9700, too and there will be videos of this little rig in the near future.
    73 and stay well
