Years ago, in the mid-60's when I was living in Warren, OH, WHLO-640 was a GREAT Top-40 station. They were 1000 watts DAYTIME ONLY BUT.....Since the station they were protecting on 640 was KFI, they were allowed to remain on-the-air until LOCAL SUNSET IN Los Angeles. In the winter, this was around 8 PM Akron Time, but in the summer, they were on until about 11 PM. Back then, their Sign/on time was at Akron sunrise. In more recent years, they were granted an increase to 5KW days and 500 Watts at night.
