Re: Noise floor on AM band Vs. micropower AM modulator?
Quick update: we turned off the halogen strip lights in the dining room/ kitchen today and noticed a big drop in noise at the lower end of the medium wave band , on an 81 year old set with a 2 metre aerial .We then switch off the overhead lights (new regs. compliant) and noticed an even larger drop... so in my case, a new build flat, these sources alone account for most of the noise nuisance on medium wave.

It was ever thus, but perhaps not to the same extent. In the 1920s the wireless-owning residents of Workington (Cumberland) complained bitterly about interference from the Lodge-Cottrell electrostatic dust-catchers on the blast-furnaces at the local ironworks!
