[UK-CONTEST] G3RIR still off the air

[G3RIR]

A short while ago I reported a noise which is causing me havoc. I have made
some progress.

Firstly I am aware that this is not directly contest related but I am
hopeful that there may be someone out there who can help.

G4BJM suggested making a loop antenna and I have built one similar to the
design in the ARRL handbook. Fraser also mentioned trying a very cheap
shortwave RX from Superdrug but they seem to have stopped selling them so I
bought a Roberts 9962 12 band shortwave RX for £30. It works very well and I
was able to walk towards the signal and track the source.

I have tracked the noise to a metal (yes, metal not wooden) telegraph pole
about 50 metres from my antennas. There are 13 (thirteen) overhead cables
radiating from the pole and I can't detect which if any of these is
radiating more rf than the others as the maximum signal seems to come from
the pole.

The noise is horrendous on 14 MHz and I have now discovered on 3.5 MHz as I
have an 80m DF receiver. The noise is wideband but peaks considerably every
50 kHz. Looking at the waveform there are spikes every 100 Hz. Even at 50m
distance it is S9 on 20m.

So where do I go from here? Knocking on 13 doors asking them to turn their
mains off etc. is too daunting. I have been in this house for nearly 30
years so perhaps this will trigger me to move to an rf quiet location if one
exists anymore.
