The AF Limiter in the K3 is designed to allow you to
protect your hearing when you have the AGC off and gain
cranked up to hear the signal buried in the noise just as
your neighbor with his beam bore-sighted on your QTH and
running the Alpha amplifier starts transmitting on that
same frequency.

Note that the AF Limiter level is completely adjustable
when AGC is OFF.  At its highest setting it clips just at
the threshold that the audio amplifiers in the K3
otherwise limit/clip.

In fact, when AGC is ON, the AF Limiter is still present
but set to this highest level.

So, if it bothers you, please set it higher :-)

Enjoy!
