Super low frequency

Super Low Frequency (SLF) is the frequency range between 30 Hertz and 300 Hertz. In this frequency range there are the frequencies of the AC power grids (50 Hertz and 60 Hertz). The radio services Saguine on 76 Hertz and ZEVS on 82 Hertz operate in this range, which is often called incorrectly Extremely Low Frequency (ELF).
