7 MHz WSPR tests with 100 microwatts

Back in February I mentioned WSPR as a means of testing an antenna's effectiveness. 

Continuously for the last week or so I've been running 100 microwatts (not milliwatts) WSPR on 7 MHz. 

About 20 stations, up to 2500km away, detected my signal. I didn't count them but there seemed to be hundreds of detections, some at quite good signal to noise ratios. This means one could easily go lower in power and still be detected. 

Anyway here's the video that goes into it in a bit more detail. 

Note: I reported 0.001w (1mW) due to software limitations. Actual power was, as mentioned, 100uW.
