KWJB was initially proposed by J.A. Windham and Lee Robinson, under the name of Mineola Broadcasting Company on March 28, 1963. The callsign of KMOO was assigned to the permit on May 8, 1963, and received a License to Cover on November 1. J.A. Windham, who by this time had bought out his partner Lee Robinson's part of the station, sold the facility to Dean Angel and Sammy Curry, d.b.a. Mineola Radio on October 23, 1967. KMOO originally operated as a 250 watt daytime only facility, from a transmission site on U.S. Highway 69, 1.5 miles north-northwest of Mineola. The facility was authorized to use an auxiliary site, transmitting from the original U.S. 69 tower, on August 6, 1974. KMOO was granted a Construction Permit to increase power to the current 500 watts on October 8, 1976, and received a License to Cover both the main and auxiliary sites on January 18, 1977. Although the facility was assigned the KMOO calls upon sign-on, and held on to the set for nearly 30 years, it was initially strictly prohibited for station personnel to refer to the station as "K-Moo" by Sam Curry of Mineola Radio. Instead, the station branded as "K-M-double O" for many years. The current continuation of KMOO, which still resides in Mineola at 99.9 FM, having signed on by Curry as the FM counterpart to this facility in 1977 at 96.7 MHz, is indeed now referred to as "K-Moo", instead of the long time "double O" brand associated with the KMOO calls. After nearly 30 years of service to Mineola on 1510 kHz, the KMOO calls were replaced, with this facility being re-assigned the calls of KJMC on July 2, 1993, while the FM counterpart remained KMOO-FM, as it is currently. KJMC would again change calls to KVCI on September 8, 1994. On January 23, 1997, KJMC filed a Major Modification to leave Mineola and build a new transmission site 2 miles south of Canton, as well as changing its Community of License from Mineola to Canton. This move would be granted and issued a Construction Permit by the Federal Communications Commission, with the facility receiving a License to Cover from the new site near Canton exactly one year later on January 23, 1998. KVCI would request and be assigned new call lettersKRDH on January 1, 2007, and being issued the current KWJB calls on July 4, 2012.
