Hi...
Right now, at 08:46 July 7 2005 UTC, I hear a "bell" chiming on 5744 kHz, USB. There are about seven "chimes" every five seconds or so. The pitch of the chime is a 'G' below middle 'C'. There's a reasonable amount of fade on this signal, and its not very strong here in Auckland. A WUN search reveals nothing significant. Any ideas? Mark. Auckland New Zealand. |

In retrospect this is rather interesting:
"08:46 UTC"? What time did the London bombings begin? "about seven 'chimes' every five seconds" Seven/Seven = Date 7th July? Hmmm, I wonder if the frequency "5744" can be made to fit this coincidence? "Mark" wrote in message news:1120726599.482295@ftpsrv1... Hi...

I'm no musician. What note does "Big Ben" in London play? "Panopticon" wrote in message ... In retrospect this is rather interesting: "08:46 UTC"? What time did the London bombings begin?

"Panopticon" asked in message
... "The pitch of the chime is a 'G' below middle 'C'." I'm no musician. What note does "Big Ben" in London play? Mr. Panopticon, For an explanation of the pitch of the note played by "Big Ben", please see http://www.hibberts.co.uk/strike.htm For your convenience, an extract of the pertinent information follows: "Big Ben has a nominal [pitch] of about 335Hz (it is doubletted) which in musical notation is E + 27 cents. Actually, the dominant note we hear with this bell is a secondary strike of about 440Hz, i.e. an A, based on a partial above the octave nominal with a frequency of 883Hz" Mark.

Auckland New Zealand. --------------------------------- As a long time guitarist I found the link fascinating. I attended a Christmas service with hand bells, and thought they sounded "odd". Odd as in I noticed the bells didn't sound like "pure" notes. I now understand, to some degree at least, why. I also found it interesting that Rayleigh also made breakthroughs in understanding how light "waves:, and thus radio, behaves. Terry |
