Radio emission from the Earth occupies a wide range of electromagnetic waves (30 kHz – 3 GHz). In what wavelength interval is the Earth’s radio emission from space recorded?

Radio emission from the Earth from space can be recorded only at high frequencies (over 30 MHz), since low frequencies are screened by the ionosphere.
