"Over the horizon" optical experiments

Since 2013, my health has precluded proper field experiments at 481THz or thereabouts (optical). I am just too wobbly. I tried once, but I just could not manage it sadly.

One of the things I enjoyed was experimenting with weak signal optical signalling over the horizon. My own tests used QRSS (slow CW) received on a PC . There was absolutely no sign of the optical signal in the sky, yet there was a clear trace visible on the PC. 

Had I been well, these experiments would have continued and far greater ranges would have been possible.

Hi Roger, Great article and links thanks. Please note that the link provided for UKNanowaves is the old Yahoo Group which seems to have migrated to Groups IO.

Thanks Mike. Link (hopefully!) now changed.
