Just received my newer (06/2011) PL-310. This one is silver as opposed to the black early model I had, and Elmered. This one does OK, and is quieter on AM band, with a few usual suspects around 730kHz.One thing this set has is a . . . kind of buzz (very low freq.) when pushing a button that the other set did not have. It does not affect performance AFAIK. Also, this set bleeds a little AM onto the LW band, slight, but in a quiet place, there is a faint talking at level of intelligibility.
