This evening I read the FT8 and FT4 guide I purchased for just 10 euros, and I have to say — it’s excellent. Even as an experienced operator, I found it clear, comprehensive, and packed with valuable insights. Perfect for beginners and still incredibly useful for seasoned hams. Highly recommended!

I bought and read the FT8 and FT4 manual, and I must say I’m truly impressed. It’s a clear, detailed text that traces the entire history of digital systems in amateur radio communications. Thanks to this guide, I finally understood concepts that had eluded me before — it’s really helping me deepen my knowledge in this field. Congratulations to the authors!
