This is a Windows only program.

- Integration with N1MM, WSJT-x, JTDX, JTAlert and FLDigi
- Radio CAT control via either Omnirig or Hamlib
- Call lookup by multiple external sources QRZ, HamQTH, QRZCQ, HamCall and internal Clublog
- Propagation analysis using VOACAP linked to call sign lookup and cluster which predicts probability of a connection (Contact)
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.
Next create your logbook database. I chose SQLite database. It’s easiest and a fast database. 
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.
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.

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.

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 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!
Hola colega este programa es solo para Icom 7300 e Icom 7610 73’s…
Hola, esto funcionará para mini radios. 73!
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 Richard,
Thank you for commenting and your input. I hope everything is good where you are.
Take care and best 73!
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?
Hi Mike,
Thank you and I hope all is well where you are.
I just use the electronic QSL and will send cards out if people send me one. So I can keep track of those electronic ones easily.
Try their forum. It has a section on Awards.
Grid Tracker will also track awards for you.
Take care be safe and best 73!
Rich, Thanks for all this information on Log4OM. But, I perceive it’s a MS Windows application…NOT
LInux?? Hope I’m wrong?
Hi Harold, yep it is Windoz. I use MLDX and RumLogNG on my Mac.

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 Ken,
Good to hear from you and thank you for commenting here.
I don’t know the answer to that one. Try the forum here.
GL, and good DX!
