>=3B Oh yes. But it is a little early in t= he year and it will reduce as it
>=3B does on the other low bands=2C = with some zero static days. When we had
>=3B the band some years ago= =2C we were mostly using CW and QRSS3 over
>=3B shorter distances (my= record was about 1100km) but we tended to
>=3B operate early in the = morning when the static was at its lowest.
>=3B
>=3B I reduce th= e interference here by using the quite effective noise
>=3B blankers = in my Afedri SDR receiver=2C together with lots of fast AGC.
>=3B The= n heavy limiting and a further noise blanker in SpecLab. The
>=3B res= ultant 'holes' are small compared with the QRSS60 bit length.
