Q: Radio station 106.7 used to have the True Oldies Channel with Scott Shannon. Did the True Oldies Channel go to another station?
-- Doug Lowman, Marietta
A: The change was made in November, when True Oldies 106.7 became Atlanta's Greatest Hits 106.7. Shannon was the midday host, with the playlist programmed by his New York-based True Oldies operation. The True Oldies Channel cannot be heard in Atlanta but in these Georgia towns: Jesup, WIFO-FM (105.5); Lyons, WWBT-AM (1340); Swainsboro, WXRS-AM (1590); Bainbridge, WMGR-AM (930); and Young Harris, WYHG-AM (770), according to www.trueoldieschannel.com.
Q: An article in the Feb. 17 Atlanta Journal-Constitution Sports section states, “NASCAR has reduced the size of the restrictor plate in an attempt to cut speeds before the season opening Daytona 500.” The article later states, “The plates limit an engine's power by reducing the amount of air that flows into the carburetor.” I don't understand. To reduce the horsepower, it would seem you would enlarge the restrictor plate size to further restrict the airflow, not reduce the size, which would seem to allow more airflow. Can you explain?
-- Robert Lackey, Marietta
A: When NASCAR refers to reducing the size of restrictor plates, it actually means reducing the size of the opening in the middle of the plate, NASCAR.com's David Caraviello said in an e-mail. "It's basically a metal plate with a hole in it -- the bigger the hole, the more air (and thus horsepower) it allows. The smaller the hole, the less air and horsepower."
