Arduino-type project on the cover of QEX – for those who have followed Ardunino and open source hardware over the years this is big deal we think!
The September/October issue of QEX is coming soon, and it is full of theoretical and practical technical articles that you don’t want to miss. Richard Chapman, KC4IFB, shows how to use the Arduino prototyping board to design a project, and then gives us a lesson in programming the microprocessor to “Build a Low-Cost Iambic Keyer Using Open-Source Hardware.” W. G. Moneysmith, W4NFR, was a new repeater trustee needing a duplexer for a 70 cm repeater. He presents his solution in “A Homecrafted Duplexer for the 70 Centimeter Band.”
