What is "kdtl-ld"

KDTL-LD is the Retro TV affiliate serving the St. Louis metropolitan area.

It began as K64DT in 1990. It increased its power, changing its callsign to KDTL-LP in 2004. Its callsign refers to Daystar Television St. Louis. Its former callsign, K64DT, was randomly assigned and has no meaning unlike the similar callsign it has now. On January 5, 2012, the station changed its call sign to the current KDTL-LD, reflecting its transition to digital broadcasting.
