There’s plenty of white noise on radio bands between stations, FM or AM, it’s got plenty of flavors. Any old radio would do.

- throwaway15908 4y agoAre you sure, there is no signal in background radiation? Someone should check.
- digitalsankhara 4y agoSure, it's possible but there are plenty of gaps where its random noise - but even a very very weak signal would be swamped with noise if the radio is in FM mode. Pure radio static is the sound of the universe! Very frequency dependent - the higher up in frequency (or shorter the wavelength) the more of it is cosmic in nature - point a microwave radio dish towards/away from the sun and hear the difference, or even down towards the ground to hear the sky/earth noise. [1] I personally find a clear spot between military submarine stations in the low frequency 10-60 KHz range quite relaxing to listen to as it's a mix of random noise and thunder static. Go VLF or ELF for earth sounds; https://theinspireproject.org/default.asp?contentID=17 https://theinspireproject.org/default.asp?contentID=17 [1] https://en.wikipedia.org/wiki/Radio_noise https://en.wikipedia.org/wiki/Radio_noise
