Log4OM 2 Installation

If you want to try this, go to Log4OM and download the latest version.

After the download, unzip the file and run the installer exe file.

When you see the option to install OmniRig, go ahead and install it, unless you already have it. We’ll be using OmniRig for CAT.

Log4OM 2 Initial Set-up

You can start the program by double clicking the desktop shortcut. On the initial start-up you’ll have to enter your station information. Mine is below.Log4OM 2 Station Information

Next create your logbook database. I chose SQLite database. It’s easiest and a fast database. Log4OM 2

If you have one, export your old log to an ADIF file. I saved mine to the desktop.

Next you’ll want to import your old log (ADIF file) by going to the menu and choosing File>Import ADIF. When the window opens, click the load button and navigate to the file from your old log.Log4OM 2

Radio CAT Control

I’m using OmniRig because it works so good and it’s simple to setup and use.

While installing you can choose to install OmniRig. If you find later you need it you can download and install it from here.

Below are some screenshots from my initial setup.

Radio Configuration

I do my best not to change anything in the radios internal settings. These setting will work with all of the software I use. See my Icom 7300 and Icom 7610 screen captures. Have a look at the notes on those pages.

Log4OM 2 Quick Look Video


I have a video showing some of the nice features of Log4OM 2 and how to configure it for WSJT-X.

I’ll also have a video using HDSDR as the receiver on the 7610. The notch filter is worth trying!

More traveling in the near future with a new antenna!

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.

    I have been using N3FJP’s ACL. What are the main features I would gain?

    Hi Larry,
    It’s great to hear from you and really good to hear you back on the radio. Log4OM has more features than AClog. It will upload to more online logs and will track awards. Two of the features I really like are the propagation forecast and the clusters. I’ll do more on those. If you have room on your computer I think it’s worth a try. It’s free and if you like it you can send them a donation.

    I am looking forward to the picnic in September. Keeping my 🤞 73!
