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.

'QRT' is the Q-code used in amateur radio to tell someone to stop transmitting. Hams very much anticipated the day when Germany and Japan would be defeated, the war would end, and they could go home to resume their beloved radio hobby. You might know - or not - that during World War II ham radio transmissions were prohibited in the U.S. for a mix of reasons. Foremost was to inhibit the broadcasting of information, intentionally or unintentionally, that might give away strategic military strategy. Innocent chatter about whose son left for boot camp, where he was going afterwards, what his ambitions and fortes were, which factory Mom and Aunt Rosie worked for and what they did (Auntie was riveter, maybe), who died in service to his country, blackout hours, scrap material recycling collections, all was potential fodder for enemy tacticians. Another reason for the prohibition was to free up production materials and labor for the making of military equipment. The fate of the free world depended on it - literally.
