Greetings fellow Elecrafters,

The purpose of the roofing filter is to reduce receiver generated
distortion products, not to provide selectivity. Are you sure that that:
1) the strong signals are completely out of band;
2) the only distortion products are those generated by the K3 itself,
and not the transmitter.
