There are couple of points to keep in mind if you don't use the AUX input

Are you sure about this? A snubbing diode has to have fast turn on, but

hello all,
Anyone try this: listening a S7 to S9 signal (SSB) on any band with
your headphone, at this time, try to
enable NR, you will hear a really LOUD audio!
Maybe need firmware upgrade to fix it.

I can confirm this. I've heard it on strong SSB signals and it's easy
to demonstrate with the XG2 signal generator set to the 50uV level.
The more aggressive the NR setting, the louder the strong signals
become. Using the XG2 and the K3's built in AFV meter, NR F1-1 gives
a 3.1 dB boost
Confirm this one also, I dont operate SSB but tuned in a couple
stations to
try it out and it will blow your ears off when you hit the NR button.
Did not reload older software to see where it took place but its new on the
last release or so.
