The studios are in Radio Towers Park on Benham Street in Hamden, where it shares facilities with sister stations WELI and WAVZ. WKCI-FM transmits a full Class B signal, broadcasting with 12,000 watts[2] from a 915-foot (279 m) tower, the equivalent of 50,000 watts at 500 feet (150 m).[3] The station's transmitter is on Madmare Mountain in Hamden near the WTNH transmitter site (where WKCI-FM formerly transmitted from until moving to its current tower in 2003).[4]
WKCI-FM began broadcasts in HD Radio in December 2004.[5] Its HD2 signal airs a mainstream urban format, providing a second option to WZMX, and is simulcast on FM translator W265DB at 100.9 MHz, known as "100.9 The Beat"; this format signed on the air at 12a.m. on June 23, 2015.[6]
