KDKA (1020 KHz), Pittsburgh and WBZ (1030 KHz), Boston used to come in here in Louisville much clearer than they do now. The virtual break-up of their formerly clear channels with flea-powered nighttime power allocations to other, smaller stations, IBOC noise, and the occasional Cuban jamming excursions on 1000-1100 kHz (particularly against WHO, 1040 kHz Des Moines) renders them unlistenable at times.
Pirates Baseball on KDKA with Bob Prince and Bruins Hockey with Fred Cusick and Cal Gardener on WBZ during the '60s, '70s and '80s...I was a regular DX listener!
