The idling sound pattern is what is intriguing to me, and it got me thinking about it being a radar, or something else that act similarly.

Re: [Spooks] XSL Question
Visit http://mailman.qth.net/mailman/listinfo/spooks to unsubscribe from this list Agreed that the idler which goes nosiree bob, nosiree bob, nosiree bob bob bob is for sync and channel probes. This waveform is only used in Japan and has stations of varying range on ~13 known frequencies. The data segments (payloads) are obviously encrypted and usually they have the same chop-chop-chop as the idler (though not always). The casinos seem to be replacing the machine which sounds like this with newer video based money eaters. Future generations will not be able to hear something that sounds unsettlingly like Japanese secure communication every time they drop a quarter, or two, or three. -hugh __ Spooks mailing list Home: http://mailman.qth.net/mailman/listinfo/spooks Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Spooks@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
