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.

McWatts was an electronics-themed comic that appeared in Popular Electronics back in the 1950s. Artist Carl Kohler's main character is a stereotypical Joe Sixpack (actually a Joe McWatts)electronics hobbyist who dreams up unique ways to deal with situations. This edition shows McWatts in a scenario where, presciently enough, he experiences having his radio controlled airplane treated to what modern day 'drone' pilots are experiencing on a more and more frequent basis - being shot down. In this case the hostile fire came from some kids with slingshots. Fast-forward to 2015 and we are now seeing reports of people using shotguns and rifles to down the privacy-invading craft being piloted by unqualified pranksters. Back in the McWatts era, getting 'shot down' was much more likely to occur when non-protected frequency usage (27 MHz band) caused death-inducing interference that resulted in loss of control. Nearly all modern systems use bullet-proof spread spectrum modulation in the 2.4 GHz ISM band.
