That's a LeSEA station. LeSEA = Lester Sumrall Evangelistic Association. Otherwise known as World Harvest Television, the stations usually feature a "WH" combination in the call letters. Programming is a mix of Christian and family-friendly fare.
The station had been in analog on channel 51 since summer 1995, and just made the switch to digital this month.
LeSEA used to own channel 53 in the Denver area, but sold it to Libermann Broadcasting last year. As of September last year, LeSEA still aired on 53.2, branding as KWHD 53, its old calls while under LeSEA ownership, while 53.1, now KETD, airs Estrella TV.
