The carrier completes 103.3 million cycles each second. In free space, one full wave is about 2.90 metres long.
FCC channel 277 corresponds to 103.3 MHz. The channel number is an engineering identifier; listeners use the frequency on the dial.
The FCC antenna record lists an eight-section array. Antenna gain and height help explain how a modest transmitter output can produce a useful signal across mountainous terrain.
ERP includes antenna-system gain; it is not a live transmitter-output reading. HAAT measures antenna height relative to surrounding terrain, not tower height above ground. FCC engineering reference: final CDBS archive, January 9, 2024; published license listings cross-checked October 14, 2026. KKVU hardware is documented in MBC’s August 2026 transmitter report. Wavelength is calculated from the carrier frequency.
