[Elecraft] K3 NR

[drewko]

Lyle,

Your post below indicating how the F3 NR settings have been re-ordered
in the new f/w reminds me of something I brought up earlier:

When NR ADJ is on, the VFO-A knob has no function. Could I suggest
that it be used to step through the NR settings in this sequence: 

F1-1, F2-1, F3-1, F4-1
F1-2, F2-2, F3-2, F4-2, 
etc.

This sequence is "orthogonal" to the current VFO-B sequence:

F1-1, F1-2, F1-3, etc.

Having both would make it a lot easier to compare the different NR
settings and find the optimum one.

Also, is there any reason why when AGC is OFF and the NR button is
subsequently pushed it does not just automatically switch on the AGC
instead of flashing "N/A" on the display? That is pretty annoying to
those of us who frequently switch between AGC OFF and ON (and who
can't remember which state it is in whey we reach for the NR).

BTW, the NR works just fine for this typically wide-bw CW user...

73,
Drew
