[Laser] Documentation of the 1963 EOS 118+ mile laser experiment

[Clint Turner]

Hello,

After some work, I have gotten a web page describing the 1963, 118+ mile 
one-way laser communication online.  It may be found here:

http://modulatedlight.org/eos/Operation_Red_Line.html

This feat was completed only months after the first visible-wavelength 
HeNe lasers were developed with the help of a lot of volunteer and 
collaborative effort, drawing on the skills many people.  This web page 
includes a transcribed narrative provided by Bob Legg, W6QYY, audio 
clips from the original 1963 log tapes, and quite a few photographs that 
I scanned during a recent visit to Bob's QTH in California, along with 
detailed annotation containing information provided by Bob and a few of 
the other participants.

During this recent visit, Bob, Chris (VK3AML) and myself completed an 
impromptu 2-way optical QSO across the valley:  At just under 8 miles, 
it didn't break any DX records (the distance was so short that the 
receivers were driven into partial saturation when the optical 
transmitters were running at full power) but we all had great fun doing 
this:  Pictures and audio from this QSO will be placed online soon.

73,
