Many of the daytimers on clear channel frequencies had a 'critical hours' lower power to protect the full time stations on the frequency from interference. Especially this time of year, if you tune the AM dial from about 3pm to after dark, you still get all kinds of small stations cutting in over the larger ones. Driving home today at 3:30 I was picking up on 890 what I believe was WHNC, a 1,000 watt daytimer southern gospel station from Henderson, NC.
