[Elecraft] KX3 Voice Monitor

[Don Wilhelm]

David,

The part of the equation that you are not realizing is that there is an 
inherent delay in DSP processing that may not be apparent with your 
ICOM-7600 but is present in the KX3.  The audio through bone conduction 
will be apparent in your ears before the audio from the monitor.

The delay will not not be much, but it will give rise to a similar 
response (as you said) to the AFX delay response.

73,
