Sounds as if its the end of an era. From what I have read HD radio is better on FM as AM has its limitations,especially on the sidebands.
Last time I DXed any AM station was WRLL 1690 when they had the oldies format..Since they weren't 50 kw as WLS and the former WCFL was...it faded in back and forth with a station from Baltimore.
Growing up on the farm in the 1960s when I was a skinny 'ol geek gave me opporitunities to DX AM radio since I had no shortwave radio at the time.
Ron Britain on WCFL with his comedic gags and trying to tune in Super Max Kinkel on CKLW after they powered down and switched its direction pattern after sunset proved a challenge before Trans World Radio from Bonaire faded in. WLAC in Nashville with its Top 40/R&B format and overnight black gospel with the late Bill "Hossman" Allen was quite a unique listening experience. When 660 WNBC NY and 670 WMAQ Chicago aired NBC Radio's weekend "Monitor" program,I managed to tune my transistor to the sideband between the two frequencies and had a really cool echo effect while Murray The K was interviewing Mick Jagger or Gene Rayburn plaing some MOR/Top 40 crossovers. The Monitor electronic sweep sounder introducing the top of the hour news sounded even more cool.
CBC Radio's compartively more eclectic programming in the evening stirred a young country boy's imagination and inspred me to broaden my horizons to enter the biz and get away from being a potential borderline redneck.Wish WCOL-AM had a strong signal back then so I could have listened to them when that station was great..At least there was WING and WIZE's Top 40 at that time...before the signal faded in and out at sundown and again at dawn.
That was the 1960s and early 70s when radio was still fun. I miss those days.
IBOC coupled with the corporate greed has destroyed radio's magic since back in the day.
