I mentioned that Roger, G3XBM was shifting from the very low frequencies to much higher frequencies. His interest has already uncovered some links that I hadn’t seen before. One very cool thing was his discovery of a local 477Thz beacon (that’s red light) that is aimed roughly in his direction at a distance of around 30km. The beacon is the work of GB3CAM, and uses ten 10mm red LEDs, running with about 400mw DC power input. What a cool idea! The entire circuit consists of a PIC processor and an XR2206 monolithic function generator.

It appears that the UKNanowaves group on Yahoo! is a pretty lively group. I’ll be watching this closely.
