[Laser] My first experiments

[Paul M0EME]

I finished my light receiver yesterday, it consists of a 4" lens from a 
cheap magnifying glass and a K3PGP receiver and a unknown photo diode. This 
was all followed by a TBA820M audio amp driving a pair of headphones.
I had success bouncing modulated 1mW laser off some conifer trees 200 feet 
away, and a star causing a rustling sound in the headphones. A plane going 
overhead sounded like a heart beat because of the flashing landing lights.
All in all I am happy with my first experiment.

73's and thanks de Paul.
