Stefan es Friends
If you need all these add on gadgets for LF es MF  ie lazers, fm repeaters,
carrier pigeons then the Cause is Lost.
Concentrate instead on proper LF Antennas, Sensitive receivers and plenty of
RF, this way and you will achieve the object!!

Hi Stefan,

Clint Turner http://ka7oei.com/ has interesting information on his

"optical

communications page"

http://modulatedlight.org/optical_comms/optical_index.html.

Linear's design note DN399 about photodiode amplifiers may also be worth

reading

http://cds.linear.com/docs/Design%20Note/dn399f.pdf (it uses a BF862 FET

which I

think is already one of your favourites).

Oops... 650nm wavelength is perhaps O.T. on this reflector.
