So been playing with noise cancellation, big mag loop on 160 and noise antennas
Got the 24 hr s9 plus crap smpsu on the big loop removed.just atmospheric noise now at s4..its really difficult at night to judge as so much more atmospheric noise that gets confused with local noise..ie short nvis crap from all of london! ( smpsu noise is not just local..if there is enough of it..)
