Hummmmmm...... I shall have to try an earth on my system considering the improvement given in your report elsewhere. It'll only be the electrical earth picked up from the lighting circuit(s) in the loft. Getting to the MET would be tricky but not impossible. Enclosed the E-field board and 90 mm of thick copper wire probe yesterday, it's now wire down from the ridge board in the loft. Does catch the occasional signal that I don't think is a local switching transient but it also gets a fair bit of MSF on 60 kHz, the other VLF transmitters aren't obvious.
