Westwood One's site, under Sunday Doubleheaders, lists WEEI, WPKZ, and a couple of WEEI's sister stations in MA
(but they'd pre-empt it for Pats talk or other stuff--Celtics yesterday I think). They do list, for NH:
HILLSBORO WTPL-FM 107.7 Varies, Check local listings
Have picked them up in Haverhill, faintly
NASHUA WGAM-AM 1250 Varies, Check local listings
NASHUA WGHM-AM 900 Varies, Check local listings
Both of "The Game" stations do offer other sports though. Under next Sunday's listings they say they'll
do Pats from Wembley Stadium with pregame beginning at...10 am. Then they have Cardinals-Giants from WW1
at 7:30...

--Under previous ownership, WESX and WJDA used to carry NFL Sunday afternoon games
--For one week, 98.5 offered one...since Pats were on a Monday night, I think
You may have better luck certain weeks, like Nov 1 when the Pats have a bye week, or on times when Pats have a game on a Sunday or Monday night
