[Elecraft] K3: honest question re Audio Peak Filter

[Jan Erik Holm]

Indeed!, Doug got this right.

In a previous msg I did say why not but thinking more
about it, after reading this, I will agree that it´s not
needed.

Too many darn functions to fiddle with anyway, enough
is enough.
As I stated in a previous message, fix the flaws and
get done with it, the K3 is a very nice product as is
but a few bits and pieces needs fixing.

Anyway,......happy new year / Jim SM2EKM
