Hi Stefan

I use his detector and modulator circuits for my system.

LF,
Just thought about trying a LF RX in the forest and feed the signal
via a laser link to the building here. There is a good direct view to
several suitable places, a good 1000m distant from the city. A simple
laser diode, driven at 15 to 20 mA should work fine for some hours
when having a solar panel that charges during the day. You know these
small lamps for the garden with a solar panel, switching on
automatically when it gets dark...
Just seen HA6PC at OE3GHB-grabber but nothing here or at DF6NM (yes
Mal, i know, you've all worked them in the past...).
Pure AM is probably not the best choice, rather FM.
Does someone of you has useful experiance of such a laser system or
even a ready to use circuit or some hints about a compact IC that does
the job?
No warnings about the danger of laser light please.
