RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB.

Here is a little more tech comic artistry from Bill Hutchinson. Bill created a lot of work for Popular Electronics over the years in addition to his semi-regular Hobnobbing with Harbaugh series. One of the comics mentions an operator being referred to as a 'lid.' In Hamdom, the term means a person who is incompetent or stupid. The history of 'lid' is apparently uncertain (as is 'Ham') per many sources I checked, but two explanations seem the most feasible to me (not that either is necessarily correct). The first is that in the olden days of land telegraphy, less skilled Morse code operators supposedly placed the lid of a tobacco can over the speaker to clarify and amplify the sound. The second is that 'LID' stood for "License In Doubt," meaning the operator was so bad that he likely was not certified. Enjoy.
