Analog-to-Digital Conversion History
The transition from analog to digital television (DTV) for KKJB was unique due to the timing of its construction permit. Because the permit was granted after the Federal Communications Commission (FCC) finalized the DTV allotment plan on April 21, 1997, the station was not assigned a separate companion channel for its digital operations.
Consequently, KKJB utilized a process known as a flash-cut. Instead of broadcasting on two channels simultaneously during a transition period, the station simply shut down its analog signal on UHF channel 39 on or before June 12, 2009, and immediately activated its digital signal on the same frequency.
Following this transition, the station continued operations on channel 39 for several years. However, on November 30, 2018, KKJB officially switched its broadcast frequency from channel 39 to channel 15.
