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.
TSM Reviews: Yaesu
FTM-3200DR Digital/Analog 2-meter Transceiver
By Cory GB Sickles WA3UVV
In
mid-March, Yaesu surprised just about everyone with the announcement of a new
transceiver, capable of analog FM and System Fusion operation. The FTM-320 (DR/DE)
is a 2-meters only, 65-watt radio, with front-facing speaker and a simple
black-on-amber, dimmable display. Its small dimensions mean it can fit just
about anywhere. With a current street price of $180, he believes many hams are
destined to be looking for just such a spot.
How
to Become an EMI Detective
By
Mark Haverstock W8MSH
In
a world full of electronic technology, it’s inevitable that there will be an
increase in electromagnetic interference (EMI), especially on HF bands.
Computers and their peripherals are the biggest offenders, causing a host of
problems for those of us in the radio hobbies. Not far behind are the infamous
AC power supplies known wall-warts and power bricks. And don’t forget the
plasma televisions! Mark shows how to diagnose your EMI problems and how to fix
them.
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.

By
Mike Kohl
Change
is a constant in the field of Free-to-Air (FTA) satellite-TV. While some
channels continue as they have for nearly two decades, others, particularly the
last of the DigicipherII subscription channels may be on life-support. FTA
satellite-TV expert, Mike Kohl, reviews all of the C and Ku-band satellites
viewable to North American locations and explains what you might expect to find
on those channels.
