Q&A

Russ brings his own brand of troubleshooting, circuit design, and all-around electronics know-how to Nuts & Volts. Each month, he personally answers an interesting mix of reader questions on almost any electronics topic from computers to radio to electronic bean counters. Started in June 1996, the column was originally hosted by noted electronics writer TJ Byers who passed away in January 2007. TJ was a staple in the electronics community and is greatly missed.
