[QUOTE="TimeFlipper, post: 157066, member: 6456"] You reminded me of a radio receiver facility thats been known and used by Radio Hams for many years, and its called a heterodyne.. This is where two higher frequencies join together to form a lower frequency, so its possible maybe that two of your coils will develope 185Khz and the other 215Khz (purely as an example) and when they merge, a lower frequency audio signal is formed, such as your whistling sound :whistle: :D.. In our older radio receivers there would be what is called a Beat Frequency Oscillator (BFO) which is a dedicated oscillator thats used to make an audio frequency signal from Morse Code, audible...It would also have a variable pitch control that helped make the sound lower or higher in pitch, which helped individual listeners like Prof Opmmur and me who are "getting on a bit" ;) :D.. I cant think of anymore ways to possibly describe your whistling phenomena :D.. [/QUOTE]
