Welcome to my website on “Old School” QRP radios!

These sites deal with “hardware defined” radios. Although I think, that SDRs are a great invention, this website is dedicated to the “old school” style of building ham radio transceivers. That means using classical filter circuits, mixers etc.

Should you have any questions, comments or you would like to buy a radio kit, components or other material, please mail

peter(at)dk7ih.de !

Please keep in mind that the designs are free for non-commercial use and for educational purposes. Any commercial exploitation would violate this copyright. Thank you!
