Well, 1490 WGCH Greenwich in the 1980's before it even went 24/7, never mind Business Talk Radio
WICC 600 Bridgeport still sounds full service, though they are listed as News/Talk. The station has music on weekend mornings and even when there are rain delays for Yankee games.
WILI 1400 Willimantic has scaled back their music a bit, but still offer local programming like Wayne Norman--who has been "Mr. WILI" since 1970.
WINY 1350 Putnam--though most of its AC music is bird-fed (Jones), still has a local presence like some local DJ's a talk show weekdays, a sportstalk program Saturdays and a commitment to local news.
And someone mentioned 860 WSBS in Great Barrington, don't forget 1230 WNAW North Adams.
There's also 1490 WBCB in Bucks County, PA--no satellite programming whatsoever (save USA Radio Network News), but these guys are uber-local 24/7--tons of sports including Phillies baseball. Merrill Reese, the voice of the Eagles is one of the owners. Even more impressive, you can hear them online
And on the FM side, same for 95.9 WATD Marshfield--Ed Perry's award-winning station on the South Shore of Mass. I have listened to them online--FANTASTIC!
So at least in New England and the northeast, Full Service still has a heartbeat.
