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 App v1.00 Released !

It's been a lot of work with a steep learning curve, but at long last the first RF Cafe App is now available for download from the Google Play website! An iPhone version will probably be created if my motivation level is elevated enough by a huge number of downloads for this Android version.

RF Cafe App v1.00 (download on Google Play) - RF Cafe

This first release is meant to 'test the waters' for the usefulness of an app whose purpose is to provide reference material rather than a collection of calculators. Whether you are in the lab, at your desk doing design work, or operating in the field, there are times when you need data. These first few screens are some of the most often needed information.

If enough support is received, the RF Cafe App can be greatly expanded into a vast volume of formulas, sketches, tables, definitions, and other encyclopedic content not just for electronics, but for mechanics, physics, mathematics, chemistry, and more. Depending on the resulting file size, separate apps might be required to accomplish the goal.

Everything contained herein - and much, much more - is available on the www.RFCafe.com website, so please do visit often. Notice that there are no 3rd-party ads in this app and it is being distributed at no cost. The best way to support my hard work while getting something else out of it for yourself is to visit the websites of my RFCafe.com advertisers to determine whether their products and/or services are useful to you.

Thank you. Please send your feedback to kirtrfc@aol.com

Sincerely, Kirt Blattenberger, KB3UON
