Well, I've been considering returning to the bands after many years with my vintage kit. A 'stealth' vertical at the end of the garden amongst the trees seemed the best idea. A few years ago I put in a comprehensive earth system when I relaid the lawn.
However, S9 interference from all manner of electrical gadgets, neighbours' household wiring acting as QRM transmitting aerials, overhead telephone lines merrily pulsing with data, planning issues, risk of neighbour conflict once metal and wire is raised in the air, risk of blame once anyone's TV reception has a wobble, prolonged lousy HF band conditions, and now the knotty issue of earthing raised in this thread...
So, I've had an idea: Let's forget it and do something else.
It was all so simple years ago. No wonder amateur radio is dying.
