A better 70cms

Now that the data on 440.4125 has gone off in Barrow, I've got a better 70cm band. It used to be strong enough to cause problems on my Icom IC-7000 at home with it appearing at various frequencies in the top half of the amateur band. This was a problem when I was trying to hear D-Star signals which are in the 438 - 440 MHz area.
There are strong local signals in the 453 and 456 MHz bands but these don't cause any problems as they are only on-site business radio users so using a bit less power.
