Our Sony 6R-11 Supersensitive TRF was the first radio I heard KNX 1070 on in SE Michigan. It was circa 1969, and of course my first impression was traffic and weather every 10 minutes. I heard KFI 640 and even KNBR 680 on a Sony AM FM Cassette Portable. The FM on it was great for the time, before all the new stations, translators, LPs, Canadian border squeeze ins, and IBOC, or in my opinion IBOAC sidebands.
