If you have no immediate need for one of the products offered on RF Cafe, please consider making a donation toward the effort.
I have never passed on your information to anyone (e-mail address, name, etc.). Running the web site and keeping fresh information available is time consuming and costly.
Please be as generous as possible - $50 doesn't buy what it bought a couple decades ago. In fact, according to the BLS's Inflation Calculator it is equivalent to $35.10 compared to when RF Cafe began in 1999.
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.
