The company's radio stations consist of 40 frequency modulation
(FM) and 12 amplitude modulation (AM) stations located in Arizona,
California, Colorado, Florida, Nevada, New Mexico and Texas. The phase control and amplitude modulation of
separated oscillatory fields are discussed for the measurement of the
T-odd correlation term. The entire suite of
audio effects includes: Amplitude Modulation, Chorus, Delay/Echo,
