Hopper, supervisor, at the zone and interzone telegraph console in the Springfield station of the Illinois State police radio system. During the past three years of operation the apprehension of criminals has rocketed to record-breaking highs. Since the adoption of radio telephony, the percentage of stolen cars recovered has, for example, jumped from a scant 13% to a new high of 83%. Photograph through courtesy of Western Electric Co.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived... All trademarks, copyrights, patents, and other rights of ownership to images and text used on the RF Cafe website are hereby acknowledged. My Hobby Website: AirplanesAndRockets.com
Please Support RF Cafe by purchasing my ridiculously low−priced products, all of which I created.
