[edit] Beginnings: As WISR-FM

WLER-FM's beginnings, like most FM's, were rather humble. The station began as WISR-FM, when the AM license had been issued for those same call letters when the license was first granted in 1941. The ownership at that time, Butler Broadcasting Company, chose to turn the license back to the FCC after having the FM license failed to make any kind of an impact financially.

[edit] As WBUT-FM

However, the license was recovered years later by WISR's AM crosstown competitor, WBUT (AM). The station operated as WBUT-FM for many years until the early 1980's, when the call letters were changed to WLER-FM, and the station began to originate more of its own separate programming, though much of it was done through voice-tracked automation. The station was an adult contemporary formatted station for much of its existence.

[edit] Today as WLER-FM, AllHitz 97.7

WLER saw its biggest change in the spring of 2006, when they shifted their music format to a more hot adult contemporary/Top 40 hybrid and adopted the moniker "All Hitz 97.7". Where its two AM affiliate stations tend to serve Butler County, WLER gravitates more towards the suburbs north of Pittsburgh, as well as surrounding communities such as Grove City, Franklin, Mercer, Kittanning, and New Kensington.
