[Laser] FW: Eclipse Wave Files

[Terry Morris W5TDM]

Hi All,

Here is an email I got from Mike Coutore. He is a member of the list, but 
can't seem to get his posts to go through. He has a wav file at the link 
below that he thinks may be Earth light on the Moon during the Eclipse. See 
his email, the go to the link http://mgte.com/laser/  I had to open the wave 
file by copying the Eclipse link into Media Player, it wouldn't open the 
player just by clicking the link.

Link to paste into Media Player 
<http://www.mgte.com/laser/last%20gain%2060%20short%20one.wav>

I haven't seen any other posts on the EME light polution on the Moon, guess 
everybody is resting up after the long night.

>Spectran Set-UP
>Vol, 1/3
>Speed, 1/3
>Gain, 2/3
>Base, 2/3
>Bright, Min
>Contrast, 7/8
>
>Controls:
>Resolution, 2.7Hz
>Sampling Rate, 44,100 (fixed because of wav file)
>Display resolution, 2100Hz to 3700Hz
>
>If you move around the spectrum down near 0Hz you'll notice some
>straight lines and fixed noise oscillations. I have NO idea what I
>have. Here are the items used:
>I-Key+, digital recorder (running at 44kc) full CD quality
>C-5658 Hamamatsu Detector (specs on laser page)
>Sodium Filter, ~560 - 620nm
>Everything is battery operated.
>There was a sodium light about 250 feet away buty I had it blocked
>with a large piece of plywood so the mirror could NOT see it.
>25" mirror on az/el mount
>
>After downloading the file I increased the base line 60db through
>amplification. So the file you see is 60db higher then original,
>except for my voice at the beginning.

>Upload this to the list. Mike
