*Log4OM – Features

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?

Just giving this program a try and like it, gonna make the switch. I was using HRD. Only thing i would like to see work are FLRig with version 2 and also would like the map to be more like Maclogger DX with the spinning globe 🙂

Hi there – I’m sure it’s my own lack of understanding of how QSL confirmations work – but I’m not understand the process for receive/sending QSLs, what the status values mean, how this works for awards, etc.
I’ve read the manual but it doesn’t clear up my questions – any insights or suggestions on where to find guides?

Rich, Thanks for all this information on Log4OM. But, I perceive it’s a MS Windows application…NOT
LInux?? Hope I’m wrong?

I have version 2.11, It is very difficult for me to figure out how to use it. I really like the cluster to find a dx station in the older version. I deleted that version and lost all my contacts. But I would rather go back and use a older version. I was more comfortable with it. Is it possible to get a older version?

Hi Rich,

Kind of late on this thread but I was going to take your advice on LOG4OM and integrate it with Gridtracker and FT8. But, the LOG4OM setup process won’t recognize my .adi data file from HRD? So I’m stuck right at the beginning. Any hints on who to talk to about this? I’m running windows and an IC7300.

Like you, I’m running ic-7610. I’ve got the CI-V USB connected to the PC and also have the CI-V phono-plug connected to a linear amp (SPE Expert 1.5k-FA). Works fine when using the DXLab commander (PC controls freq etc. and linear follows along). With the Log4OM+OmniRig, the CAT commands to the linear seem to fail — the linear does not switch bands and its tuner does not follow. It seems the Log4OM+OmniRig are interfering with the CI-V phono-plug interface (perhaps telling the 7610 to shut if off). I’ve had to re-load a previous setup from memory card to get things back to normal.

Since your setup may be similar, any suggestions?

Would love your thoughts, please comment.x
