This week I had the pleasure to interview Martin, IW3AUT. He’s the developer and founder of the Italian PMSDR Software Defined Radio receiver. In this interview you will get a look inside a successful SDR project. You will read about the design goals, the milestones of the project, the problems which Martin encountered an how he solved them. Enjoy the interview!

Just found a cool vintage style video Ham Radio video on You Tube.

Enjoy the video!

Did you know that in 2009 more than 6000 Softrock kits have been ordered? Isn’t this an impressive number? Even having no concrete figures how many HF transceivers have been sold this year by the major brands like Yaesu and Icom, the trend is unoverseeable. The popularity of Software Defined Radio has increased significantly in 2009.
