Bojcha, thanks for the suggestion.
I spent some time tweaking the preset, i also took you suggestion.
However, as there are differences between airchains, the preset will sound most probably in a different way in your headphones than in mine.
This time, along with the preset, i also uploaded a recording directly from a Sony MP3 player (recorded from live radio). The background ticking comes from the MP3 player and the 17 KHz sine you can hear is also caused by the radio's circuitry (probably because it's too close the the transmitter). Anyway, hope you like it.
Here is the recording (16 MB Compressed WAV File):
