It’s all very well to say that, but these are the daytime noise figures for my set-up under battery power with the house power turned off:
80m S8
60m S8
40m S7
20m S7
18m S7
15m S5
12m S2
10m S2
All this noise may be originating in electronics that have noise suppression components omitted, but they are not in my house and I have no access to them. How about hunting them down? Fine in theory, BUT: on my street houses are every ten metres or so. I can put a whip on my FT817 and walk up and down the pavement and the noise barely alters from one end of the road to the other. One has to conclude that it is either coming from every house, or from the cables ducted just below my feet. Now it would be nice to live in a utopian world where all the sources of RFI are electronics under my control, but I live in a real world polluted by RFI from a myriad sources that are not accessible to me. Frankly, I have more chance of looking out of my shack window and seeing herds of wildebeest majestically depositing dung in my garden than I have of fixing these issues. Since you are so sure that £££BIG-MONEY£££ (£ - I live in the UK!) will prevent any action, I can only conclude that amateur radio is doomed because hams are prepared to bow under pressure and potter about fixing the noise sources under their control and living with the rest, instead of kicking up hell about the situation.
50-odd years a ham and I have to watch ham radio go out with a whimper. Vale!
