After the loss of its main transmitter site, due to the sale of the land the array sat upon, KEYH went silent from December 31, 2020, until December 27, 2021. KEYH's previous format, prior to going silent, was Regional Mexican, with sports programming interspersed. KEYH is owned by Estrella Media and upon getting back on in late 2021 temporarily rebroadcast Estrella Media's sister station "La Raza" 98.5 KTJM. However, in early 2022, KEYH began broadcasting classic hits with the branding name "Joe 850". The launch of "Joe 850" made a classic hits comeback to the Houston market.
Under normal operations, KEYH is licensed to broadcast with 10,000 watts; because AM 850 is a clear-channel frequency reserved for 50,000 watts Class A KOA in Denver, KEYH was required to reduce power at night to 185 watts. The former transmitter location was near Denver Miller Road in Sugar Land, Texas.
