HF noise levels

It is sad how much the noise floor has risen at my QTH in the last few years. Listening on 160 and 80m is now almost impossible on a vertical because of the wideband noise that obliterates the band to an S8-9 level. The noise is there right through to above 17m. Thankfully 10m with the horizontal halo is still pretty clear. Apart from my experiments at VLF and LF I am now tempted to move back to the VHF/UHF bands for serious operation.
