Light: The new frontier?

These days Amateur Radio is broadening its horizons considerably towards the low and high frequency ends of the spectrum. Recently I participated in Steve VE7CA's 473kHz 630m crossband night November 1st UTC. Earlier this year I had my first QSO on Infra-Red.



I made a Video and PDF about Light Wave basics:

My Light Wave Gear:
Below I have some photos of my Infra-Red gear which I used to QSO with VE7SL, who was 70Km away and at sea level, from about 300m on a nearby mountain (to guarantee our first try would work!). We had very strong signals both ways using MCW. I could even see the red light flashing by eye! Code copy was considerably easier using the MCW receiver though! The gear was not difficult to build and expensive.
