Building SD Radio...


My interest in building an SD radio, got a push from good old friend Mr. M V S Sarma, without whose help, I would not attempt to build this Software Defined Radio. The article was published in May 2007 issue of Elektor Electronics. He helped me with the Cypress chip, programmable clock generator CY27EE16 a hard to find chip! It gives immense pleasure to listen to this SD Radio. The antenna used is Inverted V. Following are some of the pictures of my home-brewed unit.
