About RF Cafe
Copyright: 1996 - 2024 BSEE - KB3UON 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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

If only eBay had been around at the end of World War II, this surplus equipment would have dominated the electronics and electromechanical gizmo categories. Electronics magazines of the post-WWII era were filled for years with advertisements like this one from G & G Radio Supply Company in a 1953 issue of Radio & Television News. That B-29 bomb sight, like the one used on the Enola Gay, could be purchased brand new for a scant $295, which even in equivalent 2018 dollars of $2,758 (per the BLS), is a steal. This is not the famous Norden bombsight, but it's still a sweet collector's item, which is available on eBay today if you would like to own one. Already have a B-29 bombsight? How about a complete IFF (Identification Friend or Foe) secondary radar system? For a mere $350 you could own a complete rack of RC−188−A equipment, including the rack and chassis, a 450 W power supply, a 157-185 MHz transceiver (not in the Ham bands), a 5" CRT display, and a slew of vacuum tubes and components.
