More WSPR with 20mW

I’ve been WSPRing on 30m today, still with a power of 0.2W. I think WSPR is more interesting when you use low power: it’s always interesting to see how far you can get.

20mW is not the lowest power you can use, though, it’s just the lowest power the K3 will comfortably produce. (You can set the output power to 0.0W but I’m not sure how accurately the rig will maintain the power at such a low level – something to check.

Today my 0,02W into the MFJ magnetic loop in my attic was received by 30 different stations. Here’s the list:
