Guys, don't side bar it, though I am in FL I am also working on LOS comms.
I am interested in speed and reliability within what the medium will permit.

I and another guy locally are working on LOS links too. By way the source
of some good diodes are bad DVD RW devices, they have both 650 and
720 nm high power diodes in them.
