[NLRS] 10 GHz & Light Youtube

[Doug Reed]

Yes, lots of good info on the modulatedlight.org web page. Mostly under 
two years old. I like his info on focusing the transmiter LED and the 
difference between Fresnel lenses. I wouldn't have thought of using 
foam-core art board to make the enclosure. I've seen some recently at 
one of the Dollar stores in town. And they have plenty of cheap picture 
frames for mounting the fresnel "whole page" magnifiers. Over-all there 
are several good ideas on the page, and I haven't even looked at the 
electronics yet.

His point about AM versus FM modulation was interesting too. If we get 
to the point of building some equipment, maybe we can run some tests to 
verify. But there are certainly some advantages of ease in the PWM voice 
modulation circuit. But I expect you need some really outstanding 
amounts of audio gain to make up for what the 2M HT receiver would give 
us. More reason to play. Using low frequency keying with computer sound 
card software might still be interesting.

I've got more reading to do....
