The Red Sox Radio Network can be anything the Sox put together themselves, say WPLM FM to the south as a start, remembering WPLM has already been the Red Sox flagship, WBOQ gets them decent coverage on the North Shore where WPLM doesn't reach, toss in the AM's up in NH, and a Worcester affiliate and you have pretty good coverage.
Would or could WPLM preempt the Queen of Sap ( Delilah) at night to run ball games during the week?
They would probably not want to screw around with Ron Della Chiesa on the weekend nights.. good question.
I guess it depends on how many night games there are on the weekends.
Look at WXRV's signal on 92.5, add that to PLM, BOQ, CRN and you have coverage from Worcester to Boston to the cape to the south and most of Southern NH,
