WHA (970 kHz) is a non-commercial AM radio station, licensed since 1922 to the University of Wisconsin and located in Madison, Wisconsin. It serves as the flagship for the Wisconsin Public Radio talk-based "Ideas Network". WHA's programming is also broadcast by two low-powered FM translators, and by WERN FM's HD3 digital subchannel. The station airs a schedule of news and talk programs from Wisconsin Public Radio, NPR, American Public Media, Public Radio International, the Canadian Broadcasting Corporation and the BBC.
The same call letters are used by WHA-TV in Madison, the flagship station of the Wisconsin Public Television network.
WHA, transmitting on 970 AM, reduces its power from 5,000 to 51 watts during nighttime hours, in order to protect Class A radio station CBW in Winnipeg on 990 kHz from interference. This results in limited coverage within Madison city limits. To increase its availability, WHA's programming is relayed by two FM translators, plus the HD digital subchannel of a third FM station.
In 2009, translator W300BM, operating on 107.9 FM, which previously carried Delafield-licensed WHAD, changed to relaying WHA, to provide coverage to downtown and eastern Madison, including the University's Madison campus. WHA is also simulcast by FM station WERN's HD3 digital subchannel. In early 2013, translator W215AQ, transmitting on 90.9 FM, and also serving Madison, began rebroadcasting WERN's HD3 signal, providing a second FM transmitter carrying WHA's programming.
