The daytime-only station previously operated a news/talk format featuring Joy Browne, Glenn Beck, Rush Limbaugh, and Sean Hannity.

The transmitter site for WMRF was moved to the WLTN-FM site in Derry Township (Big Ridge) just north of Lewistown to provide for an economical operation as at the time a licensed engineer was required to be on duty when the station was on the air.

The FM operation was not financially viable and in 1954, the license was turned back to the Federal Communications Commission (FCC).

The company applied and received a grant for 95.9 MHz, which signed on as 100% simulcast of WMRF in 1964.

In 1988, WIEZ applied to move to 670 at 5.4 kW daytime and give up the 1490 full-time frequency.
