About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024

    BSEE - KB3UON

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...

U.S. Military Abbreviations & Acronyms:  E

The military and government are famous for using - or overusing - abbreviations and acronyms for designating equipment, programs, and agencies. These eight pages are chock full of nearly every commonly used abbreviations and acronyms used by the U.S. military (at least up through around the year 2000).
