K3 - lightning static reduction

[Bill-3]

I received an email from a trusted friend that mentioned a new menu
adjustment that prevents the AGC from acting on sudden bursts. Any info
on that? I must have been in my cave that day.

You may be referring to the AGC PLS (AGC pulse) setting, which prevents
a short pulse from activating AGC. It is on by default.

It is intended to prevent the situation, common on some receivers, that
a single strong pulse deafens the receiver for a long period. I don't
think this would be helpful with lightning static, though, which is
repetitive longish pulses.

See the AGC PULS entry under the CONFIG Menu - Tech Mode section of your
K3 Owner's Manual.  I think your friend meant that he newly discovered
the feature, it has been in the radio for a very long time.

This is also very useful as part of the combination of settings that will
nullify key clicks to a surprising degree.  Sharpest possible skirts will
convert the typical form of a key click to a very sharp pulse. The normal
AGC PLS setting will "freeze" AGC for a very short period, but sufficient
to prevent the pulse from pushing down the instaneous RF gain.  With IF NB
off, DSP NB t1-7. t2-7, and t3-7 will take care of the key click audio per
se, making it possible to operate with some pretty bad clicks nearby. The
DSP NB does not have the artifacts that IF NB has to have in crowded
contest conditions.

73, Guy.
