LW MW HF FREQUENCY GUIDE
The following is a guide to the main frequencies used by international broadcasters. These frequencies are to be used as a guide only as many stations are now locating themselves "outside of the band" to escape the congestion of the "official bands".
ULF - Ultra Low Frequency (3-30 Hz) ELF - Extremely Low Frequency (30-300 Hz) VF - Voice Frequencies (300 Hz-3 kHz) VLF - Very Low Frequency (3-30 kHz) LF - Low Frequency (30-300 kHz) MF - Medium Frequency (300 kHz-3 MHz) HF - High Frequency (3-30 MHz) SHORTWAVE FREQUENCIES BAND GUIDE
