Yes, that's why I mentioned (90 minutes before your post) that:

    The Ronja Metropolis, fancy as it is, is too complicated.

I'm currently thinking along the lines of something very simple. A FET op-amp 
feeding a Schmitt to buffer the reciever and a simple emitter-follower to run 
the transmitter LED via a serial (RS232) port. Even if I only get 38400bps at 
that range, it will fulfill the requirement `at least as fast as a modem'. 
And who knows, I might even get 115200 bps for as few as 11 components plus 
lenses, tubes and mounting. I can't see anywhere that this has been done 
before, but it seems an obvious approach to me.

Cheers; Leon
