Two beams so you only count one way? Or just divide by two?
Mmm, I hadn't thought of that. I guess divide by two would be easiest, all depends on space I guess.

Looking at the TX / RX demo code in.ASM it looks really difficult and Bruce's code not much easier, although I can understand some of that, would be good to try and figure and learn over the Winter.

To my mind, sending data through the air has something mystical / magical even about it. I'd like to crack rf.

Right, I'm off to me bed.

Night, night mackrackit.
