I feel smarter now – there actually is now a second 50kW am station in Arkansas. A listing I found on http://www.radiostationworld.com/ says that KLRG operates 50kW (day) and 220w (night). The bloggers opine that this is the station for sale, and not KAAY.
KAAY is 50kW (day) and 50kW (night-directional).
Here is the FCC listing http://www.fcc.gov/fcc-bin/amq?call=KLRG and assorted related data.
