The Eagles' Joe Walsh: "I'm an Analog Guy"

The Eagles' Joe Walsh: "I'm an Analog Guy", Kirt's Cogitations #354 - RF CafeEach month, the American Radio Relay League's (ARRL's) QST magazine runs a feature called "Member Spotlight." Usually, the person being paid homage is a non-celebrity who has done remarkable work to promote Ham radio. Occasionally, a well-known celebrity type gets the honor, as is the case with the December 2023 issue's personality, Joe Walsh (WB6ACU), who has been the lead guitarist with the Eagles rock band since the mid-1970s. Joe earned his license waaaay back in the year 1960, when Morse code proficiency was a requirement. In the articles he states, "I'm an analog guy. I like knobs more than a mouse." Many older Hams share the sentiment.  Having spent my teenage years in the 1970s, I am of course very familiar with the Eagles and the name Joe Walsh. Don Henley, though, is probably the name most associated with the Eagles...

ChatGPT: Inaccuracies in Technical Responses

ChatGPT: Inaccuracies in Technical Responses, Kirt's Cogitations #351 - RF CafeSince January, I have used ChatGPT to generate many mini essays on various technical topics such as company histories, biographies on notable engineers and scientists, physics principles, and industry standards. My goal is to reduce the amount of references to off-site information like Wikipedia. A careful reading of ChatGPTs replies is always performed because inaccuracies appear fairly often. Overall, I find it very useful, but caution is needed. In example, today I queried ChatGPT for an equation of the voltage distribution along a half-wave dipole antenna. It took three rounds of correcting its response to finally get an accurate answer...

About RF Cafe

Copyright: 1996 - 2024


    Kirt Blattenberger,


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...
