Speed Race: CW vs. Text Messaging
Los Angeles - May 13, 2005 - In a contest held on The Tonight Show Show, the speed of a Morse Code operator was pitted against the speedy thumbs of text messaging. CW contest operators Chip Margelli and Ken Miller showed that Morse Code was faster than text messaging. The text messaging team was text-messaging champ Ben Cook of Utah and his friend Jason.
The message delivered by both teams was, "I just saved a bunch of money on my car insurance." Miller noted that Cook was entering the last two words of the message when the CW transmission was complete. Miller estimates that he was sending 29 words per minute.
The ARRL reports that the CW team used Yaesu FT-817 transceivers on 432.2MHz. Margelli sent his message with a Bencher paddle.
A video clip of the event is available at this link. The WMV file is about 13MB.
Amber Alerts via Cell Phone
Washington - May 17, 2005 - The Associated Press reports that the wireless industry has enabled Amber Alerts via text messaging as a free service in every state on most carriers. There are currently about 225 Amber Alerts issued each year. The alerts are distributed via the Internet, radio and TV stations and highway signs.
Cell phone users who want to receive such information can designate as many as five Zip codes to monitor, much like an EAS receiver can be programmed to activate for FIPS codes. Subscribers can also be notified of alerts issued for their states or metropolitan areas.
Subscribers with phones capable of receiving text messages can register at www.wirelessamberalerts.org or through participating carriers' websites.

Boston Tests FM411
Boston - May 19, 2005 - FM411 is a new consumer service being tested in Boston before debuting nationwide.

FM411 makes this data available to radio station management, who can acquire the rights to notify individuals minutes before their station plays the listener's requested music. The service is free to consumers.
