The station is operated by Audiorama, a related company to Radiorama, and is known as KY (pronounced like "calle") with a pop music format.
XHDK operated as part of Grupo DK, which included XEDK-AM, XEDKR-AM, XEDKT-AM and XEDK-TV.
The 2015 partial merger of GRM into corporate cousin Grupo Radio Centro made XHDK a direct sister station to XEDKR again.
On September 3, 2020, Planeta moved to XHKB-FM 99.9, which is owned directly by Radio Centro, unlike XHDK.
After that, the station began broadcasting test programming with a Latin pop format, until September 14, 2020, the station formally launched as KY 94.7, a brand new urban music format.
