[Elecraft] Serial Get of KX3 NR Icon Status

[Mark Johnson]

I have a KX3 and use a computer to control the radio, especially when using
digital modes.  From the Elecraft K3S/K3/KX3/KX2 Programmer’s Reference I
was able to identify and test the commands for turning Noise Reduction NR
on and off (SWH19).  I also identified and tested the commands for setting
and getting the value for the level of noise reduction (MN143).  I cannot
identify a command sequence for programmatically determining the current
state of NR (on/off).  I can get the state of NB and NTCH icons. Can
someone point out what I have missed?
