I have seen the figure "37% of all radios" in a couple different places re: KJR in the early-mid 60s, but legitimate numbers that can be corroborated are tough to find.The local press mentioned something like 50% of radios tuned to KJR, I think it was during one of the several articles that came out on Pat O' Day during the 80s and 90s. Maybe they were using a different system, or it was exaggerated, or one show only.
