KZCH (96.3 FM), also known as "Channel 963," is a Mainstream Top 40 radio station licensed to Derby, Kansas, and serving the Wichita area.

KZCH signed on November 10, 1977, at 95.9 MHz, and initially aired a country format as KDRB, "K-96", which had studios located in its city of license (Derby), and a transmitter near Haysville.

[6] A year later, the station flipped to an automated oldies format, but would revert to adult contemporary in October 1985 as KRZZ.

KZCH, along with other iHeartRadio stations, partner with KSNW when tornado warnings are issued in the Wichita area and simulcast KSN's severe weather coverage.

In 2011, it was replaced with modern rock, filling the void KANR left open when that station flipped to Spanish in 2006.
