The gimmick around election time was to dub the stations McCain 570 and Obama 1260 but shortly after the election the latter became Money 1260. 570 became Freedom 570 whose lineup starts with "America's
Morning News" which WNSH just began running I believe, then Ingraham, Jeff Kuhner, Doyle, Savage,
Hendrie, etc. Kuhner has been heard doing fill ins for conservative hosts nationally; some on the Right say they agree with what he's saying but don't necessarily like his speaking style (for some reason the Montreal native tries to pronounce every "last g" in certain words but they sound like "gk"-- "I am goingk"; "what he is
doingk", etc.) He's a Washington Times writer--certainly among the many newspaper columnists who have gotten shows (here you have Carr, Eagan, McPhee, etc.--and you will remember Barnicle...)
As for replacing progtalkwith ESPN (New Haven) their theory may be that more people are interested in sports (in terms of pitching the station to ad buyers); ESPN is a national name and, they feel, a good demo
Bonneville has indeed had various formats on 1500 in D.C.; they attempted a "left, right, and whatever we
want" talk format for awhile. It can be picked up at night here (were running Washington Nationals baseball,
Wash. Capitals hockey, etc. for awhile)
Meanwhile the parent company of WRKO, Entercom, has had a fairly successful/long-running prog talker in
Buffalo, WWKB 1520
http://www.kb1520.com/ (Their slogan "a new voice, a new choice" is running up
in Maine at Stephen King's new FM prog talker) Entercom also had progtalk on 680 in Memphis but changed that to sports (ESPN 680 also // on 92.9; when I was in Memphis in August I was able to get both stations which were doing the Red Sox on ESPN Sun night baseball)
