I'd be interested to see the EMC Test Report on the P3, required for selling into the EU and I think Australia, the P3 should not radiate emissions at this level and pass EN55022 or similar standards. Perhaps Elecraft could comment please?. I was thinking of picking up a P3 at Dayton but may hang fire...
As hams we have no right to complain about PLT, Plasma TV etc if we don't keep our own house in order.
