KBDZ (93.1 FM) is a commercial radio station broadcasting a classic rock radio format. Licensed to Perryville, Missouri, it serves the southern suburbs of St. Louis and also serves Cape Girardeau. It is owned by Donze Communications.

Weekday mornings begin with Randy Raley. He's followed by the "After Breakfast Show with Kevy Kev," then “Zav and the Classic Rock Cafe”, hosted by Chris Razavi. In afternoons, the DJ is Katy Kruze. The weather forecaster is Sean Ballant.

The station signed on the air as KRAA on November 29, 1989; 35 years ago (November 29, 1989). On September 21, 1990, the station changed its call sign to KBDZ.

When the station first went on the air, KBDZ was playing soft rock music. That changed after the Flood of 1993. The station dropped the soft rock format and switched to country music after sister station KSGM AM 980 went dark because of the damage to the transmitter site in Perry County, Missouri.

The local news and sports programming were also switched to KBDZ. In addition, the station became the local network affiliate for St. Louis Cardinals baseball and St. Louis Blues hockey.

Prior to a change in format, KBDZ was given permission to upgrade its signal with the construction of a tower in Weingarten, Missouri. The construction permit allowed KBDZ to increase the effective radiated power (ERP) from 6,000 watts to 50,000 watts. An additional change to 36,000 watts using a higher tower was later approved.

However with the upgrade, the station was forced to move Cardinal baseball to sister station KSGM AM 980 because of the FM signal's penetration into the St. Louis radio market and overlap with Cardinals flagship station 1120 KMOX. KSGM AM would eventually drop St. Louis Blues hockey but added the team back to the station's sports lineup in October 2019.

Then, in November 2013, KBDZ switched from "B931 Country" to "Classic Rock 93.1". The station featured longtime Missouri and Illinois radio personality JC Corcoran’s “The Morning Showgram”.

On February 15, 2016, Corcoran debuted on KBDZ during the morning drive time slot. The show lasted for five years. On June 8, 2021, KBDZ announced through its official Facebook page that Donze Communications and JC Corcoran were parting ways, due to a variety of reasons that were staying private. But the station said the decision was in relation to Corcoran “inaccurately and unfairly attacking personnel”.
