Topband: Bev. and power lines.

[W2PM]

Corona noise is near impossible to null even from a single source I've found.  Fortunately my offender is spark gap noise causing a specific multi point waveform signature. As I understand it however corona is far more likely at the higher voltages. Also FYI here in the US FCC will not enforce interference rules on corona noise which is why so many power companies are quick to diagnose complaints that way.

Whenever the weather was damp, misty or raining (or all three simultaneously as this was in England), I basically could hear nothing on 160m on any sort of antenna. Attempts to null the noise were complete failures as there were multiple sources of corona. When the weather was dry everything was fine.
