2021 481THz tests

It is about 7 years since I last tried anything on 481THz (red light). 

So, today I dug out my optical beacon TX and RX and tried some tests across the house. Although I could find the RX, my TX beacon took some finding! This is mains powered. I eventually found it in a cupboard and did some tests. 

Tonight after dark, I shall try bouncing the signal off the windmill.

The last test I tried was in early 2014, but I was too wobbly.

Small steps.

UPDATE 2200z:  I tried "windmill bounce" and "tree bounce" on CW at 10 wpm but it was too easy! Signals were very strong. One thing is clear: I am much more wobbly than I was 7-8 years ago. I'd like to try much greater obstructed paths with QRSS, but wonder if I am up to it these days.
