Christer and the group.  I was delighted to get the two URL's
containing the 30 Hz filter and noise blanker.  You might
some years ago the "HDO" phase linear filter.  That was when I
was W6HDO rather than K7RR.  For years that filter served us
well.  I really enjoyed the experimental way of finding least
ringing, so I placed variable resistors in the old design
an automatic key.  Even the old Williams textbook approach
benefited from experimental "tweaking". 73 Cliff K7RR
