Why not use a 50hz comb filter to eliminate the harmonics of the mains??? I
have a 60hz comb filter kit that I am building to help out in the US.

Hi Jim
Your Jason signals were quite strong and, in the pauses of noise, the
waterfall was completely black and only the lines of signal were clearly
visible, unfortunately the noise, probably due to te 2750 th armonic of the
mains, was walking up and down on the band, from time to time crossing the
frequency and filling the waterfall. The time appearing on screenshot is our
summer time, UTC+2 hours. 73 Cesare
