Please Contribute to RF Cafe

If you have no immediate need for one of the products offered on RF Cafe, please consider making a donation toward my labor. Running the RFCafe.com website and keeping fresh information posted is time consuming and costly.

Please be as generous as possible - $25 doesn't buy what it bought just a couple years ago thanks to massive inflation. In fact, according to the BLS's Inflation Calculator it is equivalent to $12.44 (about half) compared to when RFCafe.com began as RFTools on Earthlink in 1996. I don't get cost of living increases, have no insurance, no investments, and no retirement plan.

An alternative could be to donate test equipment, technical books, or other hardware items that might not be useful to you any more. I can always find a good use for stuff.

I have never passed on personal information about website visitors (e-mail address, name, etc.).

Thank you.

Sincerely,

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.
