Hey Yankee.
I just found out about this today, quite bummed.

I use WCBS as a deep fringe test station for homebrews and other experiments .Its the only
dependable day time New Yorker here in Boston , though admittedly, some days are better than others.
It can be fair to good N. of Boston , even into NH and
be useable into S. Maine.
No other daytime NYC comes close.
I also REALLY liked it for the actual content for bedside listening of national and NY news, weather, etc.
During day it gets a bit squeezed against a moderate strength local on 890 at times,but not too bad.
But goodbye to the CONTENT side of things ( like NYC really needs yet ANOTHER AM all sports format station

. ).
Apparently , as you mentioned, the station was still making money, but apparently Audacity didnt want two similar stations ( along with WINS) in the stable, so they cashed out WCBS.
WINS is pretty much only available here after sunset.Usually just a beat note ( if even that much ) during the day and never has any useable audio.At night, it STORMS in , often better than WCBS ( go figure).
Both do QSB some at times, INS is probably a bit more prone than WCBS , or should I NOW say 880/WHSQ ( yuk).
INS 1010 is up against 1030 BZ ( BZ is at + 55 here). But on a decent rig usually not a big problem, maybe a bit of monkey chatter at times.
So while I still have NYC news content, it is now night time only, boo

!!.
Yet another chunk of the old AM band goes bye bye.
