Normally referred to as "Oldies 102.1", KTMB is alone among Anchorage radio stations in that it has no live DJs and guarantees to tell listeners the name and artist of every song played.
On September 7, 2011, at 12:01 am, midway through The Black Eyed Peas' Just Can't Get Enough, the then-KDBZ changed their format from modern AC (branded as "102.1 The Buzz") to Adult Album Alternative, branded as "102.1 The Peak".
On March 7, 2014, KDBZ changed their format to classic hits, branded as "Oldies 102.1", soon after changing their callsign to the current KTMB.
