KCYY (100.3 FM) is a radio station broadcasting a Country music format. Licensed to San Antonio, Texas, United States, the station serves the San Antonio metropolitan area. It is currently owned by Cox Radio after the sale by New City Communications.

The station previously has had an Adult Contemporary format, known as KLLS, or "Klassy 100", until switching to country.[1] It is headquartered in Suite 600 at 8122 Datapoint Drive in San Antonio.[2] Its transmitter site is in unincorporated Bexar County near Government Canyon.


During the 1970s the station was KSAQ ("Q-100") which had a contemporary top-40 Format. KMFM was on 96.1 playing a middle of the road format. By the early 1980s KMFM flipped to KSLR 96.1 FM Son Light Radio as a Christian format. Salem communications acquired rock formatted KMAC 630AM and flipped it to KSLR 630 and KSAQ moved to 96.1FM/760 "Super Q" and KLLS 100.3 was reborn as Adult Contemporary "Class 100 FM."
