Here's the list I am aware of. These are the only talk-based stations I know of that carry live and local programming overnight.
TALK RADIO
WBZ Boston
SPORTS RADIO
WFAN-AM-FM New York
WZGC Atlanta
ALL NEWS
WCBS New York
WINS New York
KNX Los Angeles
WBBM/WCFS (FM) Chicago
KCBS/KFRC (FM) San Francisco
KYW Philadelphia
WTOP Washington
KOMO-AM-FM Seattle
and in Canada, All-News stations
CFTR Toronto
CKWX Vancouver
CHQT Edmonton
WLW Cincinnati is a Talk station that runs a live Truckers/Country Oldies show overnight. KOA Denver recently switched from local programming to Coast to Coast. WWJ Detroit is an All-News station that, as a cost-cutting move, simply repeats an hour of news till dawn, rather than having a live anchor all night. I have doubts about CHQT Edmonton having a live anchor all night, considering how small that market is, but I am not sure.
Obviously some Talk stations, such as WOR New York and WTIC Hartford, have a live person doing news updates all night, during a syndicated show such as Coast to Coast, but I am restricting this list to all-live and local programming on News, Talk and Sports stations.
