[Elecraft] K3 noise reduction

[Don Wilhelm]

Windy,

The amount of audio reduction depends on how much noise reduction you 
have cranked into the K3.
It is not fixed in the latest firmware, but the situation has been 
identified.  The method used to correct it has not yet been settled, but 
it will be corrected - perhaps by allowing the user to set the amount of 
gain increase when NR is active.   I find the K3 NR is quite effective, 
but the audio level change is disconcerting.
This is not a problem when the NR is used on CW, it is a SSB/AM problem 
only.

73,
