Good idea, never done that before. I really should think about finally getting rid of that QRP signal and work to get a decent signal...

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.
