The Red Sox have left Great Eastern Radio's and Sugar River Radio's stations in the Upper Valley (WWOD 93.9, W234BN 94.7, W294AB 106.7) and are now on the area's three WEEI affiliates (WEEY 93.5, W232DN 94.3, W233CC 94.5). I think this is a mid-season switch, because I'm almost certain I heard the Sox on 93.9 during the first week of the season, and Joe Castiglione was voicing appeals for sponsors that were airing on the Great Eastern stations all through the off-season.
