[Laser] Re: RTTY over light, anyone tried it?

[C. Turner]

Hi Paolo,

Keep us apprised on how things work out!

Also, a quick mention that I've made some corrections on the web page:  
Another reader of this list pointed out a few errors that had crept in 
as the web page had been expanded and (especially) when I redrew the 
schematics.

Things are, hopefully, less-incorrect now!

73,

Clint
