Thanks for report, Paul!
This morning, with the second transmission, I almost hit the "noise hole".
Instead, the last one was 80% sent when the rain forced me to shut down the
TX: too much kV for a wet and pretty small inverted "L" (12 m high, 36 m
long) :-)
I'm looking for a new antenna, inspired by Stefan: near my house, there are
two guard rails spaced about 700 m which are of interest for a ground loop
experiment.
Stay tuned, as they say :-)
