About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024


    Kirt Blattenberger,


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...

RF Cafe Podcasts

RF Cafe PodcastsAt the prompting of others, I decided to give podcasting a try. Having been advised that I have a face for radio and a voice for print, there was some hesitation on my part. However, there have been many fine articles published in vintage electronics magazine that people might be willing to listen to when there is no opportunity or desire to read them. Regular features such as "Carl & Jerry," "Mac's Radio Service Shop," editorials by the great Hugo Gernsback, and other types that do not contain images which need to be referred to in order to get the gist of the content, are prime targets for podcast listening. If the podcasts prove to be popular enough, I will expand to a paid subscription. Hopefully, my reading-aloud skills will improve over time. Thanks for listening.
