[Elecraft] Roofing Filter Usage

[David Woolley (E.L)]

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.
