WNDX (93.9 FM) is a commercial radio station, licensed to Lawrence, Indiana, and serving the Indianapolis metropolitan area.

It was licensed to Fishers, and carried an easy listening format similar to the original WXTZ, which broadcast at 103.3 several years prior.

Management decided that Susquehanna's modern country music "flanker station," WGRL "104.5 The Bear," would be moved to 93.9, while a new format, under 93.9's WGLD calls, would be placed on 104.5.

A new format, soft adult contemporary "Warm 93-9," debuted at 9:39 a.m. on January 2, 2008, with a commitment to play 93 hours of commercial-free music during its first week.

This did not attract many listeners, with i94 losing the ratings battle against WNOW-FM and WZPL, along with WNTR when that station flipped to Hot AC in May 2013.

On December 19, 2014, at 3 p.m., after promoting a "major announcement about i94," WRWM began airing a "Classic Hip-Hop Holiday Weekend", forcing rival WHHH to do the same.

On November 17, 2017, at 5:30 p.m., after playing "It's So Hard to Say Goodbye" by Boyz II Men, and a 10-minute farewell montage and brief teasers for random new formats, WRWM began stunting with Christmas music again, this time as "93.9 North Pole Radio.

"[30] The station also began to post teasers on its Facebook page themed around the letter "E", and promoted that "E-Day" would occur at 9:39 a.m. on December 26.

At that time, the station changed its call letters to WYRG, and returned to CHR as "Energy 93-9," launching with "...Ready for It?"

Those doubts would be verified that May, as the sale closed, and WYRG began running liners advising that Energy would soon be "turned off" and redirecting listeners to WZPL.
