How can I find out how wide a news station's broadcast range is?

Ask them, they know their audience.

@YARNLADY

I shot them an e-mail. :)

Did you try googling it? I just googled a local NYC radio station to see what comes up and their Wikipedia page tells the MHZ and a lot of technical details about the station.

@jca2 I have been looking, but I did not think to look on Wikipedia. Unfortunately, I do not see any mention of its broadcast range.

Whoa, out of nowhere I found the coverage map.

Go to this page and type in the location or call sign for the station.

Example this is WCLB in Sheboygan, WI https://radio-locator.com/cgi-bin/finder?sr=Y&s=C&call=wclb&nav=

Once there, click on View Daytime Coverage Map
