RF Cafe Monthly Prize Drawings: 2009

Sample Prizes
(see complete list here)

Now there are two ways to win a custom RF Cafe item!

At least one winner will be chosen each month from each category. ‡ Send me an e-mail telling what you purchased and I will enter you once for each item ordered.

Winners will be notified by e-mail, so be sure to give an e-mail where you can be reached. We do not pass on e-mails to anyone for any reason.

- Please note that anyone can enter, but if a winner does not live
   in the U.S. or Canada, shipment will be limited to countries
   serviced by our supplier, Cafe Press.
- Limited to one prize award per six month period. Here are our
  2005, 2006, 2007, 2008, 2009, 2010, 2011 winners.

 
"TBD" means that the winners have been notified but have not responded. I always send out at least two notices. My guess is a lot get ignored or routed to the spam folder because of wording about having won a prize.

As of December 2009, I have spent more than $2,500 shipping RF Cafe custom prizes to winners of this monthly drawing - and that does not include the book giveaways!

Congratulations to the December 2009 Winners

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Webmaster:

    Kirt Blattenberger,

    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 tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
