"98.3 The Whip" WWHP played a mix of Classic Country, Americana, Blues and Bluegrass.  They were licensed to Farmer City, Illinois which is part of the Bloomington, IL radio market.  The station's creative use of a radio antenna as whip was a pretty great logo.

WNCC

I'm not 100% certain but I think this t-shirt is from the radio station at Northampton Community College in Bethlehem, Pennsylvania.  The artist dated their drawing to 1988 (click it bigger) and this 2014 article says the college has had a radio club for over 30 years so the math adds up.  The station currently streams online but it's unclear whether they broadcast terrestrially or via carrier current when this shirt was new.  Anybody know?

Another WNCC existed at 950 AM in Barnesboro, Pennsylvania from 1950 until 2010.  The current terrestrial WNCC has only had those call letters since 1999.

Radio Hawaii City

Decal from a Dutch pirate radio station based in Halsteren, Netherlands.  "Illegal For All" it says at the bottom of the sticker.  I cannot find any further information on the internet about this defunct(?) station.

5EZY "Power FM" is a hit music station based in Murray Bridge, South Australia.

Duke FMs

The name "Duke" automatically conjures up visions of John Wayne and nomadic, gunslinging cowboys.  So when a radio station brands itself "Duke" it couldn't be anything but Classic Country. 

WGEE / WDKF - New London/Sturgeon Bay/(W)GrEEn Bay, Wisconsin

WDKW - Maryville/Knoxville, Tennessee

WWDK - Jackson/Lansing, Michigan

All three of these stations are operated by Midwest Communications whose owner is named Duke Wright.  Coincidence?

Super Bowl LI / WGST

Tonight's Super Bowl pits the Atlanta Falcons against the New England Patriots.  As a long-suffering Bills fan, I will of course be rooting for Atlanta to beat the Brady/Belichick monster and give the Falcons their first-ever Lombardi Trophy.  My hatred for Tom Brady has evolved from a burning detestation into a begrudging respect.  He is close to being the best quarterback to ever play and a win tonight would clearly launch him to Greatest Of All Time status.  Having said that...GO FALCONS!!

Atlanta, Georgia's WGST (W Georgia School of Technology) began broadcasting in 1925 at 1110 AM.  They spent time at 890 AM before another move to 920 AM took place in 1941.  WGST now lives at 640 AM and carries a Talk format.  The sticker depicts a red Atlanta Falcons helmet like those used from the team's inception in 1966 until 1989.  WGST also carried Falcon's games the first time they went to the Super Bowl in 1999.

Anybody know what the NR/bird logo was from?  Just a fancy News/Radio thing?

UPDATE:  The Patriots won (of course) 34-28 in the first overtime game in Super Bowl history.  Tom Brady immediately announced his retirement after hoisting the championship trophy and shockingly died later that night after choking on a chicken wing.

Deadspin compiled some pretty great media calls including home radio announcers from both the Pats and Falcons as well as BBC Radio 5 and Westwood One Radio.  Listen here.
