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 ...

However, some of the webinars, classroom lessons, company presentations, and privately done videos are very useful when you have a specific problem to solve. A lot of digitized productions from old armed forces and other government entities can be really useful even in black-and-white. Here are a few videos that I have viewed recently which might be of interest to you, but even if not these, surely there is some topic you have been meaning to look up but haven't gotten around to it.
