I was re-doing the WBIR (wide band image rejection) calibration on my G11 SDR last Thu when I noticed that 20m was wide open. I decided to run 15m of RG213 coax to connect to my Gwhip resonant end fed in the garden and had a go at WSPR. My 5watts made it easily across the pond.

One thing I noticed is that there are a lot more stations on wspr than a year ago - when I got started with cw.

WSPR 20m - 5Watts
