Macbeth The Macbeth Color Checker:
The Macbeth Color Checker is a tool for serious photographers and film developers.  It provides a set of known reference colors which can be used as a setup and adjustment standard in film and video production.

The Beverage Antenna Memorandum of 1958:
This is a page about an obscure FCC memorandum about the construction and testing of Beverage antennas for reception of distant AM radio stations.
The Wave Antenna:
This is an excerpt from "Radio Antenna Engineering," First Edition, by Edmund A. Laport.  The "wave antenna" is another name for the Beverage antenna.
The No-Frills Technical Links Page:
This is one of the most frequently visited pages on this web site.  It is a big bunch of technical links without a lot of fanfare or decoration.  Lots of material about GPS, time and frequency, benchmarks and other standards, antennas, Morse Code, and other cool technical topics.  This page is sure to expand rapidly, which is both the cause and the effect of being written a no frills format.
The EBS Authenticator Word List:
Years ago, the Emergency Broadcast System relied upon this list of passwords to authenticate a national emergency warning.  Broadcast historians, as well as those of you who study the Cold War and Civil Defense, might find this interesting.  Recently expanded to include other documents about the EBS system.
A Brief Explanation of Cookies:
A cookie is a small data file that certain web sites write to your hard drive when you visit them.  A cookie is a simple piece of text.  It is not a program or a plug-in.
The Last Empty Channel:
The story of TV Channel 37, on which there are no stations, even though the other channels are becoming more crowded and more lucrative every day.  It is ostensibly reserved for radio-astronomy, although there are rumors that the channel is used for covert communications, since it is a band that no Radio Shack scanner covers.
Radio Frequency Identification Technology and its impact on privacy.
Toll Road RFID Tags
... and license plate readers, microwave sensors and other technology in use on the nation's highways.
