Many years ago we built a radio telescope out of an old ' Wire Wove ' single bed and hooked it up to an AM radio at ' ? ' frequency 21 mhz ? and played it as it was pointed at Jupiter while the public viewed it through the C14 , it was a hit
telling people that the noise you are listening to now is Jupiter as you are looking at it , exactly in sync as the radio waves are travelling at the speed of light .
Its a strange airey sound Jupiter makes .
