> From a receiving standpoint, only thing I wish my K2 had was passband skirts equivalent to the matching 400 hz INRAD filters in both IF's of my MP, ultimate measured >100 db rejection up or down 500 hz, etc. (How COULD one improve a K2 in that direction, beyond the crystal mod?) How about an extra filter board in place of the noise blanker? 73 John Morrow Gi4ksh
