OK, came across this power supply which was emitting RFI right across the lower spectrum (0.3 MHz past 2 MHz)...
CE labelled PSU, but obviously of poor quality.
took it apart and these are the pics
now I'm not an electronics expert, but from the heat marks on the PCB, I think it maybe caused by a faulty Thyristor.... but as I said I'm not an expert, so looking for people ideas/reasons why this was happening.
