It's hard to test antennas when there is no propagation to test them on. I was starting to worry that I had messed up my Wonder Loop when it suddenly occurred to me to check the front page of my own site. WebProp was showing me that conditions are disturbed, and we're in the middle of a geomagnetic storm! The wonder is that anyone was hearing me at all.
It's all very well writing this software, you still have to remember to use it. :(
