1.  It really helps if you put the particular Elecraft product you're 
writing about in the subject line.  From reading way down, it "appears" 
it's a K3.


2.  We moved last year from a rural location [38 years] and I have no 
electric fences around us now.  For the 38 years on "The Farm," I was 
surrounded by them, including ours.  If ever there was a noise source 
suited to complete extinction by the K3 NB, it's an electric fence, and 
the IF NB alone on mine totally removed all of them.  The pulses are 
short, generally NAR2-3 did it for me.  One of them had the old 
fashioned solonoid with the swinging core, and sometimes [in rain], it's 
pulses were long enough that NAR4 was necessary.  I never needed or used 
the DSP, and the IF NB has no discernable effect on the received signal.


3.  I have no idea what you're referring to with "NB light," my K3 does 
not have such a thing.  There is an indicator in the main display, "NB", 
which comes on when I turn NB on and goes off when I turn NB off.  It 
doesn't do anything when I transmit.


I'd suggest a read of the K3 manual first, then KE7X's excellent manual 
if you have it.  If you don't, I suggest you buy it, it's inexpensive 
and approaches the K3 [and other K-line products] from a different 
perspective that a User Manual.

I hear my neighbours electric fence driving me crazy, so I hold in the NB

As I understand it, I can adjust either DSP NB and/or IF NB.  OK, if I leave
IF alone and only choose DSP NB, I can run it through a range of DSP T-1, 2

VFO(a) knob.   I can get 'some' satisfaction from the DSP NB, but would like
the option of using either/or.

I can transmit as much as I want and the NB light never flashes (using the
DSP NB).  No problem.

Scenario 2.hold the NB button in, now using the VFO (b) button (for the
IF NB), I can choose NAR(7 choices),MED(1-7) & WIDE (also 1-7) .




None of the IF choices really seem to do much against the electric fence
noise except maybe WID3 one minute, then NAR4 the next. (yet the pulsing is
exactly the same every pulse and other rigs (Icoms, Yaesu's deal with it
easily)-the e-fence is a pop pop opo, never changing.

What's even odder, is that once I transmit once or twice, the NB will then
flash, and it seems to me the NB is no longer engaged - is that
correct?is the flashing a warning that you do not have the best
selection or a warning that it's now disengaged?



Is there a separate board for the NB, because it sure seems to me like it's

To add insult to injury, my ol' IC-7410 right next to it pretty much

I have ever read says the K3 should be superior in every way.



I did all my testing on an extremely quiet 17m band, CW mode, 500Hz filter.
No amount of varying the bandwidths, hi cut, locut, or an array of filter
choices, modes or bands seems to have any affect on the NB flashing. (or
it's poor effectiveness)

You need to spend some quality book time and walk away from the radio 
until you understand how it works.
Read and *understand* the *whole* manual once through before laying 
another finger on the radio.

I would suggest the KE7X books as well as the manual(s).
You first need to find out what version of firmware is installed and if 
woefully out of date, which I suspect, update that before changing 
anymore settings.


The days of unpacking a radio, putting it on the desk, plugging it in 
and having it work like you expect are over.
