The syndication service/network ran here on WNSH 1570 and also up in Burlington VT on a daytime only station, AM 1070 which called itself Eve 1070. The VT station had Stephanie Miller (Dial Global), a holdover from when they were an Air America-type lefty political outlet. Typing "Fybush women's talk WNSH" into Yahoo got my this Globe article from 2006...the network was GreenStone.

Whether an effort like that would be a success who knows, and we may well find out how well the Chicago station does.
Now when you say News Talk do you mean:
--A mostly all news station with some talk at night, like WBZ? If so, you will have stiff
competition here in Boston. A city like NY can support both WCBS and WINS but who knows.
or
--A talk station focused mostly on news/politics?
Ideally if Greater would want to sell, say, WTKK, perhaps Entercom would like to buy it
(they would still be in the 5 FMs limit: WMKK, WTKK, WKAF, WAAF). A solid signal at 96.9
would be great for a WEEI simulcast or move. But would Greater want to sell to a big
competitor like Entercom? And I would think Ent. would rather move/simulcast WEEI rather
than WRKO.
Talk radio geared toward men has allegedly been tried before; I think Pittsburgh had "the Man Station" at 93.7...didn't last too long. They had local hosts plus the syndicated Dennis
Miller (a Pitt.-area native, actually)
