WERN is a Class B FM station, with an effective radiated power (ERP) of 20,500 watts. The transmitter is off South Pleasant View Road on Madison's southwest side in the Junction Ridge neighborhood, on a tower shared with WIBA-FM.[2] WERN broadcasts using HD Radio technology.[3] Its HD-2 digital subchannel carries all classical nusic. Its HD-2 signal serves as the flagship of the WPR Music network and feeds FM translatorsW213CE at 90.5 MHz and W300BM 107.9 both in Madison.[4]
History
The station signed on the air on March 30, 1947; 77 years ago (1947-03-30).[5] It was the first FM station in the network that would become Wisconsin Public Radio. The call sign was WHA-FM, co-owned with its sister station, WHA970 AM. At first, the two stations simulcast their programming, a mix of classical music, news, university lectures and public affairs shows. Originally WHA 970 was a daytimer station. When it had to go off the air at night, 88.7 WHA-FM continued its programming.
By the late 1960s, WHA-FM began airing some programming that was separate from 970 AM. Eventually, simulcasting was reduced and the FM station sought its own identity.
The call letters became WERN in 1974.[6]
Because WHA-FM/WERN began broadcasting before current maximum levels were set by the Federal Communications Commission, the station's signal is grandfathered. It runs at a higher power for its height above average terrain (HAAT) than would be permitted today. It covers a large area which affords WPR's "News and Classical Network" a strong signal across Southern Wisconsin and Northern Illinois including the Rockford area and Metro Milwaukee.
As part of a major realignment of WPR's offerings to take effect on May 20, 2024; WHA and WERN became the flagships of the WPR News Network, successor to the Ideas Network. Two low-powered translators that served to improve WHA's coverage when that station dramatically reduces its power at sunset aired the all-classical WPR Music network after this realignment occurred.[7] The change substantially improved coverage of NPR news programming in Madison, since WERN penetrates further into south-central Wisconsin than the two translators.
