Touring the WJZ Transmitter Site in Bound Brook, New Jersey—1925
By John F. Schneider W9FGH
This month, John takes us on a tour of WJZ, NBC’s Blue Network station in New York, which debuted on October 1, 1921. Founded by Westinghouse Electric, the station was originally located in a shack, accessible only by ladder, on the roof of a Westinghouse factory located at Orange and Plane Streets in Newark, New Jersey. This was Westinghouse’s radio station – preceded by KDKA in Pittsburgh and WBZ in Springfield, Massachusetts. The 500-watt WJZ transmitter was an exact duplicate of the one built for KDKA.

Tube Tester Basics: Understanding and Restoring Emission Testers
By Rich Post KB8TAD
It’s useful to have at least one tube tester around for basic checking, especially for tubes for which you have no spares or as a relative measure of quality. But, all tube testers make compromises in testing. The most basic tester and the one most commonly seen is for emission which measures the cathode current relative to its target average. The typical emission tester also includes a test for shorts and leakage between the elements of a vacuum tube. Leakage and shorts are always tested first since an emissions circuit and meter can be damaged by a shorted tube.
