Log4OM Fldigi Setting Up Easy RTTY PSK31 CW

I had a wonderful time in Arizona and New Mexico, but it's good to be back home and using the Icom 7610. The Icom 7610 Fldigi, Log4OM, WSJT-X, GT and now add Fldigi to the mix for Easy RTTY (AFSK), PSK31 and CW. We are on a Windows 10 PC. 

Icom 7300, 7610 and many more..

The Icom 7300 I have in my camper worked FB while traveling and this post will cover setting up it, the Icom 7610 and just about any other radio. The internal settings of your radio need to be setup for digital mode operation. If you have been using FT8, JS8Call or PSK31 you'll know how to setup your radio.

Here are the screen capture links for the Icom 7300 and Icom 7610 internal settings.

Log4OM Fldigi

If you are new to Log4OM please see my previous posts:

If you have been following along or have Log4OM installed, add a line in the ADIF Functions tab. I'll show you how in the video below. You can also see how I did JS8Call in my other video here, starting at 1:04.

log4om configuration
Go to Program Configuration and then ADIF Functions

NOTE: There is no need to start the Fldigi service in Log4OM. In Configuration, go to Fldigi under Applications and uncheck the box to start Fldigi on startup.

Fldigi Setup Easy RTTY (AFSK) PSK31 & CW


If you have Fldigi installed and you are using it, this will be easy. Configure yours as seen in the photos above. If you haven't installed Fldigi, the download is here. Install it as you would any Windows program (other OS available). The first time you open it you will be guided to add information, some of which is shown in the photos above.

When finished with the initial setup, visit the sections (photos above) and enter them into your installation. When finished setting it up you will have the basics for getting started.

A note about RigCAT: I am using my COM 12 which is the CI-V cable. This cable plugs into a USB port on your computer and the other end goes into the "Remote" jack on the back of the radio. So on the Icom 7300 I typically have connected a USB cable and also the CI-V cable. You can do most things with just the USB cable, but the CI-V cable comes in very handy and is inexpensive.

Use ferrite cores on your cables.

A note about Easy RTTY (AFSK): By using RTTY AFSK you do not need an extra port for FSK keying, thus making it easier to operate Fldigi RTTY AFSK when you are using a radio like the Icom 7300.

RTTY AFSK is like PSK31, you will need to be mindful of the ALC level. Too much ALC will cause distortion. I typically run mine at 1/4 of the ALC scale on the Icom 7300 and 7610. See the video for more on this.

Whatever radio you are using, download the appropiate .xml file for your radio and place it in the "Rigs" folder of your Fldigi installation. I'll show you in the video below.

Here you can download a modified RigCAT .xml for the Icom 7610 (Download and use at your own risk).

Download other rig files for Fldigi.

There is a lot you can do with Fldigi, so much so, it would be too time consuming to go through all of it. Here is a link to the Fldigi Manual.

I will cover more on operating Fldigi in the future. Watch for my videos.

Here is a nice tutorial for the Icom 7300 and WSJT-X. Lots of good info, however I will continue to use my way of setting output power for digital modes.

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.
