1330Hz
1330 Hz, commonly referred to as 1330 kHz, is a carrier frequency in the medium frequency (MF) band used for AM radio broadcasting. The AM broadcast band in most parts of the world extends from 530 kHz to 1700 kHz, and 1330 kHz falls comfortably within this range. Because of its position on the lower end of the band, signals transmitted at this frequency can travel significant distances during nighttime via skywave propagation, though they are also susceptible to atmospheric noise and interference from other stations on adjacent frequencies.
In the United States, the Federal Communications Commission (FCC) assigns 1330 kHz to a number of stations, primarily
From a technical standpoint, 1330 kHz is subject to the characteristic attenuation associated with midband frequencies when
Beyond radio transmission, the numerical value 1330 Hz sometimes appears in audio engineering contexts, where it represents
