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 Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Cleveland Institute N-515-T Slide Rule and User's Manuals

Thanks to Mr. Joe Hernandez (KN2A), the entire set of four manuals for the Cleveland Institute of Electronics' 515-T Slide Rule are now available online! Joe bought the manuals and slide rule on eBay as a set, and he was kind enough to scan the manuals and send them to me for posting on RF Cafe. Since posting a photo of my personal N-515-T slide rules and the partial user's manual I found a few years ago, I have received many requests for the manuals.

Note: Joe is a very active Ham radio operator and invites you to visit his page on the qrz.com/db/KN2A website. He is a big time CW guy who likes to tinker. One item you really need to check out is his custom-built Mouser-40 and 3 Blind Mice CW setup.

Of Beer Bottles and Slide Rules

Pickett N515-T and Beer Bottles by M0XPD - RF CafeRF Cafe visitor M0XPD sent me a link to his brief article that aptly illustrates how a Pickett N-515-T slide rule and a beer bottle can be used to help a student understand resonance in LC tank circuits. It has to do with the oft-used mechanical phenomenon dual of an electrical apparatus - like a wire is a water hose, voltage is the pressure, etc.

Came late in life to amateur radio, where he operates the station m0xpd, conducts pointless experiments, and plays with words and ideas.
