[Laser] PWM of LED in QST

[Mike]

Hi Tim,

OK, let me take some nice pics of my 'partial' assembly along with the
schematics for both the xmitter and receiver. 

This unit uses a PIC to change the audio (voice) into digital and then
transmit it using nothing more than a cheap laser pointer. 

I will not be using the pointer but have some other units I wanted to try,
but that's another story. When I finish with the pics and such I'll again
email the group with the url link.

Hi Mike

If it's ok, post the schematic and any other info you have on 
the Ramsey kit. I don't think i've ever seen it up close.
