Bud Industries: A Brief Overview and Historical Context

Bud Industries logo - RF CafeBud Industries, founded in 1928 in Cleveland, Ohio, by Max Haas, has a long history as a manufacturer of electronic enclosures and related products.  The company was initially called Bud Radio and catered to the amateur radio market with antennas and antenna products. Over the years, the company expanded its product offerings to include various components and enclosures for the electronics industry.

AI Technical Trustability Update

While working on an update to my RF Cafe Espresso Engineering Workbook project to add a couple calculators about FM sidebands (available soon). The good news is that AI provided excellent VBA code to generate a set of Bessel function plots. The bad news is when I asked for a table showing at which modulation indices sidebands 0 (carrier) through 5 vanish, none of the agents got it right. Some were really bad. The AI agents typically explain their reason and method correctly, then go on to produces bad results. Even after pointing out errors, subsequent results are still wrong. I do a lot of AI work and see this often, even with subscribing to professional versions. I ultimately generated the table myself. There is going to be a lot of inaccurate information out there based on unverified AI queries, so beware.
