790 AM WAYY Eau Claire WI

WAYY (790 AM) is a commercial radio station in Eau Claire, Wisconsin. It broadcasts a sports radio format and is owned by Mid-West Family Broadcasting. Programming is mostly from Infinity Sports Network. It also carries Milwaukee Brewers baseball and Milwaukee Bucks basketball. The radio studios and offices are in Altoona, Wisconsin.

By day, WAYY transmits with 5,000 watts non-directional. But to protect other stations on 790 AM from interference, it reduces power at night to 123 watts. (For most of its history, WAYY ran 5,000 watts around the clock, using a directional antenna at night with multiple towers. But as the economy moved, those extra towers were sold off, and nighttime power was reduced.) WAYY's transmitter is on Black Avenue at Tower Drive in Seymour, Wisconsin. Programming is also heard on 185-watt FM translator W286CK at 105.1 MHz in Eau Claire.
