The AM frequency broadcasts during daytime hours only, to protect clear channel stations WBT in Charlotte, North Carolina and KFAB in Omaha, Nebraska.

The application was amended in April to specify the daytime-only frequency of 1110 kHz, and the Federal Communications Commission approved on July 18, provided Tison divested his interest in Tampa station WFLA.

In 1970, Suncoast Radio, the owners of future WQYK-FM 99.5, bought WALT and relaunched it as a country music station, WQYK.

The signal was simulcast with WQYK-FM until 1976, when the AM station was sold to a religious broadcaster and its call letters changed to WTIS.

On January 1, 2017, WTIS notified the Federal Communications Commission that it had suspended operations on December 31, 2016 because it had lost its lease to the transmitter site, located near the intersection of 50th Street and Causeway Boulevard in the Palm River-Clair Mel area of Hillsborough County.
