Interference Cured

Over the last few years the man made noise across  the radio spectrum has increased due to solar panels, LCD TV's etc. I have had a high level of noise here for some time and although not a major issue has not put me 'off air'. However, tonight in the shack I was moving some radios about when the noise floor suddenly dropped to about S1 on 80m and I could hear stations on there. Looking around I realised the power lead to the THD-7 had been disconnected. Bit of testing confirmed this and a rummage in the junk box found a ferrite ring. Adding a few turns of the power cable to this has solved the problem and the lower bands have now become usable.
