Nanowaves

As you will have seen, after a very long break, I took my first tentative steps back into optical communications yesterday. 

Before my stroke, I enjoyed going out in the field to see how far I could cover, especially over the horizon using QRSS (very slow CW) with PC decoders. 

Much greater distances would have been possible, then my health got in the way. 😕 

All the gear was home made. This was one of the attractions: all the gear was simple, including the test gear. 

This is a field of experimentation open to everyone. You may find some ideas on my main website.
