Prior to 3.11 I had VOX in CW on all the time. When I changed mode to SSB,

Now when I change between CW and SSB VOX stays on all the time. When I turn
VOX off in SSB it is also off in CW. So VOX is not
I see that the dramatic increase in audio level when NR is turned on has been

When I change the modes without split, everything works as it should. But as

I do not experience anything like that on my K3. What NR parameters are

Are you attempting to use NR at a narrow bandwidth when this occurs?
If so, I can understand why that might occur.

signal enhancement
Fully agree!
The guys (and ladies!) at Elecraft show the greatest courage being such an

We should always consider our input to be constructive to the K line

Don,
Try this:
1. Set mode to CW, BW to 2.00, RX EQ = flat.
2. With no signal tuned in, hold NR and set to F4-4. Tap NR twice to
turn off NR.
3. Tune in an S9 signal, or better yet, use a signal generator (I use
an XG2).
4. Set RF gain to max, AF gain for a comfortable volume.
5. Tap NR
Joe, following your instructions, I cannot duplicate this on my rig
listening to a S-9 signal. I do find that if AGC-THR is set
below 5, the audio drops significantly when initiating NR at
my preferred setting, 2-1. Decreasing the AGC SLP increases
the audio with NR engaged.

I tried your suggested settings, and yes I found an increase in audio

aggressive setting. I normally use F1-3 or F1-4 for NR and have no
problem.
I don't use NR when attempting to copy a weak signal. When the weak

disallowed unless AGC was enabled [1] in order, according to K2VCO, to
prevent instability [2].
By the way, I can observe this instability (a wup-wup oscillation)
in LSB/USB modes with an S9 carrier, and AGC settings on the light
side
Heh. My voltmeter's hearing doesn't tend to get distracted by noise.

Interesting. For CW I always use the NR to dig out the weak ones. The effect
is amazing. I believe the reason we all see this differently is due to AGC
settings. THR, SLP etc. really affect the NR.

Use normal ladder line or open wire transmission line for most of your

Steve,
My AGC THR is 008 and the SLP is 02 if that makes any difference to your
conclusions.
FWIW, a narrow bandwidth with NR off is best for weak signal reception
for me. The narrow bandwidth itself reduces the noise substantially and
my ears have to do the rest.

What's up with this Kynar wire in the KX1 kit? I seem to recall this problem
when building my first KX1. The second one is no better. It's impossible to
strip it without causing it to break - either during stripping or after it's
soldered to the board. My as seen on TV wire stripper just cuts it.
I've only just now noticed that the oscillation when NR is enabled
that I hear when tuning through an S9 carrier in USB/LSB happens only
when VOX is enabled. In fact, I just now noticed that the red TX
indicator is illuminated when this happens - although there is no
indication of power out on

I believe you are talking about the #24 wire used for the KXB3080

When in USB/LSB, NR does tend to totally null out carriers. CW does make
that wup-wup sound as it's notched out. I'm not sure why NR would be
acting as an Auto Notch but this does seem to be the case.

I've seen mention of the clock in the K3 being set from the

Yes, I've noticed the tendency of NR to null out carriers, which is
easy to observe when VOX is off. But with VOX on, the phenomenon I'm
observing is quite different than that - a wup-wup-wup oscillation
with a period of a second or so that may persist for a considerable
time after it is triggered
Hi Stan,

Hi gang,
The weekly Elecraft SSB net will meet tomorrow (Sunday, 4/26/09) at 1800Z.
We will start at 14.316 MHz, and QSY if needed. The net control is in
western Oregon, but we will need a good east coast or midwest station to
relay a few west coast signals that may be too close to net control.
Good Evening,
It has been a pleasant if hectic week. From the wonderfully warm and sunny
beginning to the chilly and inclement ending it was a typically Oregonian
roller coaster ride of weather. Sunny and very warm to snow, hail, rain, and
cold. It was not warm enough long enough for the
