From 2006 till 2018 I had my Ham Radio blog on  blogger in Czech Language. Then I was active only on twitter. I decided to restart my publication about my current projects. The blog will be in English only and there will be longer technical articles. News about propagation, QSOs, and contests will be kept on twitter.
