Stop making things difficult. Just get a filter or two and put them in.
Either ICOM brand or INRAD (which no longer lists CW filters for the 706,
but maybe the IC-703 or other rig will do same) and for CW, the 400 filter
is better than the 500 or 250 being like Red Riding Hood's porridge only in
this case Mom's porridge, in the middle, is the best.
I have tried em all, now have only the 400 and perfect, even from 9N.
