[Elecraft] xtal filter

[Gilbert J Cross]

        Have been trying to remember from the distant past . It seems to
me that it was recommended that the BFO freq. was to be set at~ 20 dB
down the filter skirt. Too far? Not enough? Or has my memory been wrong
again!!!!!!! There used to be many articles dealing with this subject but
I am not where my reference books are located.
