The oldies war is heating up on low-powered FM signals along the Connecticut River. The oldest among the oldies translators, Red Wolf's "Kool Radio" simulcast of WACM on W261DD (100.1, Springfield), has been joined by "'60s & '70s Classic Hits" on W249DP (97.7, Springfield), Success Signal's relay of WARE. In Hampshire County, Saga's W245BK (96.9, Amherst) will switch to "Pure Oldies" shortly, replacing the WHMP simulcast that airs, at present, on both 96.9 and the new W268CZ (101.5, Northampton). Farther upriver, the recent entrants in Greenfield comprise County Broadcasting's relay of WFAT's "Greatest Music of All Time" on W222CH (92.3) and Phil Drumheller's "Music Memories" on W263DE (100.5), a simulcast of WIZZ. Both of the foregoing Franklin County translators add nocturnal coverage to their AM counterparts.
