We celebrate the 100th anniversary of the Czechoslovak Republic (Czechoslovakia) on October 28, 1918. I'll be one of the special callsigns on the air. You can get very nice award for QSO with OL100 callsigns. I'll be active as OL100C.

More information about the award is on OKDXF website related to this event.

I had been dreaming about this radio for long time. Finally the dream comes truth and the Elecraft KX3 is on my desk. It takes some time to adapt to a new radio but right now I can say, it has the best receiver I've ever had!

I ordered this excellent QCX QRP TRX from QRP Labs (40m band version) at the beginning of December 2017 and had to wait almost two months but finally got it. Order volume of this kit was (and is) extremely high. You'll get very good radio for very low price. Especially the RX is really good.

Ten years ago, CQRLOG 0.1.0 was released. It already had basic features for comfortable logging like dx cluster, gray line, trx control and great country resolution thanks to tables created by Martin, OK1RR. Happy anniversary and all the best to next 10 years.

A few days a go I found an article written by UIf, DK5TX about problem with cooling fans installed in TS-590. Unfortunately I had the same problem.

Today I got a licence to my new callsign OK7AN. All new articles will be published on https://ok7an.com and new email is This email address is being protected from spambots. You need JavaScript enabled to view it.. See you on the air!

After two months we have new version! There are no big changes in the code, only two new features and a few bugs fixed. We also have the cqrlog icon back! DEB packages for Ubuntu Trusty, Xenial, Yakkety and Zesty are ready on Launchpad. If you are using my personal PPA, new version will be part of system updates.
More information in Download section.

The PA L-4B is back in the OK1KMG's  hamshack. I made over 5000 QSO using this PA. Now back to low power category :(.

I drive around this area always when I go to work or return home. It took some time but I decided to visit it this afternoon. We have a few last sunny days and it's really nice and relaxing to spend them in the nature.

This is mainly bug fix release. Packages for Ubuntu 14.04, 16.04 and 16.10 are already available on Launchpad. More details in Download section of the CQRLOG website.
