Well a diode is a diode - an led is a diode - has an anode and cathode - but it is light sensitive - probly in the same spectrum it transmits - around 700nm I forget.
There are many diff kinds of noise too - you could add filters and small transistor amps at the front end - lots of trial and error. I dont know the response time of leds on recieve - one would have to pulse a light wave to find out.
I wanted to work in light as it gets rid of the radio noise (and signals) - no time yet.
Again you just have to experiment!
Oh yeah I guess if it is turned on how can it recieve...maybe forward bias (?) so it doesnt transmit - (I think it is reverse bias for normal light output) - one or the other!
