Website Traffic Trend - January & February 2020

RF Cafe Web Statistics - January & February 2020

ClustrMaps Record (4/11 through 5/24/2020)

ClustrMaps for RFCafe.com April 11 - May 24, 2020

I set up the ClustrMaps website monitor code to on RF Cafe to get another independent count of web page visits. It ran from April 11 through May 24, 2020 and produced the following data, which is in fairly good agreement with the traffic statistics I get from my web hosting server. The code was removed because it noticeably slowed down page loads since every time a web page was loaded by a visitor, an additional call was made to the ClustrMaps (and others) server.

ClustrMaps for AirplanesAndRockets.com April 11 - May 24, 2020This ClustrMaps data is for my AirplanesAndRockets.com hobby website during the same period.

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...
