5mW on 80m - best DX 1310km

80m WSPR with 5mW output

This evening I ran 5mW output on 80m WSPR to see what sort of distance I could achieve. It was quite an eye-opener with lots of reports and some good DX, the best being LA2XPA at 1310km. The report from LA3JJ suggests that almost 1000km would have been possible with 500uW. And it is not as if the antenna here is anything: just 5m of coax to the 10m halo with inner and outer joined together as a vertical and tuned through a tiny T1 auto-ATU!
