A couple of years ago, I had the privilege of designing and building a new, state-of-the-art 50 kW transmitter site facility for KBRT(AM) in the Los Angeles market. The project was well documented in ...

Capacitors are small components with a big job—storing and releasing energy in electronic circuits. This video explains how ...

This video explains what capacitors are and how they function as energy-storing components in electronic systems. Capacitors temporarily hold electrical energy and help manage voltage and signal flow ...

[Erich] spotted a broken DVD recorder at a local amateur radio meeting and decided to see if he could restore it to working order. While he was fortunate enough that someone labeled it as having a bad ...

Myrtle Beach, S.C. — AVX Corp. has designed a ceramic capacitor that virtually eliminates the risk of short-circuit failure. Terminated with the company's FLEXITERM technology, FLEXISAFE capacitors ...

A simple ohmmeter is all that is needed to troubleshoot a potential relay. After taking all of the connecting wires off of the potential relay, measure the resistance across the 1 and 2 terminals. The ...
