[Laser] From Chris Long: SIX new web pages on atmospheric optical comms.

[Chris L]

Dear group,

In response to requests for info on our 167 km optical comms gear used to 
set the non-coherent light DX record on 19 February, I've put up a family of 
web pages with pics, text, references, audio grabs and links.

Our opening page, with photos of the mountain-top DXpedition on 19 February 
2005:

The use of ultrasound in liquid cells to modulate light, and how to buils a 
'Jeffree Cell':

And finally, a personal account of my own invelvement with modulated light 
comms since 1968:
