About RF Cafe

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...

Sherlock Ohms: Case of the Shocking Subcontractor

Sherlock Ohms: "Case of the Shocking Subcontractor" - RF CafeSherlock Ohms is a regular feature of Design News that presents submissions from readers about troubleshooting challenges and how they were solved. This story titled "The Subcontractor Zapped the Network" addresses the dangers an unbalanced 3-phase load can cause when the neutral is improperly terminated. As an electrician many, many moons ago, I encountered this scenario a couple times during trouble calls to industrial locations. Also demonstrated is the all-too-common problem of having mindless drones on staff.
