The wideband signal you clearly see going up & down in the spectrum is PLC. It's basically all over..

Ugly transmitters and aurora, a great show :)

No. Homeplug is data over in-house mains cabling, which is never insulated RF wise.

Homeplug PLC is not data over power line poles, but data over in-home mains power cables. These are not insulated and function perfectly as HF antennas causing all the trouble in the video. You cannot "dig these in the ground". Homeplug PLC is one of the most stupid inventions ever.

There used to be a social platform where politics & religion was not allowed: Hamradio. Good harmony lasted quite a while...

Will be following with much interest! Would be great to build it all in a single metal enclosure with a big red REC button :) Thanks for sharing your endeavours!

This could/should become a commercial product. Will be first in line... Great work!

Hi Steve, I used my extremely simple DIY loop based on a MAR6 MMIC and Coilcraft WB1010 transformer. Loop element this time was a bent aluminium strip, 1m diameter. Bias-T from Reuter Pocket RX: 5,7V to feed the MMIC.

RFI awards should go to neighbours themselves.
