Finally, a present for the NASCAR fan who has everything: The V4 Movement replaces the pinions of the traditional mechanical movement with a relay of 13 drive belts whose tension is controlled by turnbuckles and whose gauge measures a slender 0.50 x 0.45 mm. Cost: a mere $6k-$12k, depending on options.Finally, a present for the NASCAR fan who has everything: The V4 Movement replaces the pinions of the traditional mechanical movement with a relay of 13 drive belts whose tension is controlled by turnbuckles and whose gauge measures a slender 0.50 x 0.45 mm.

About RF Cafe

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 tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
