We traced this (on Saturday, because it's not just a job, it's a lifestyle :)
to incorrect AF gain scaling with some combinations of AGC threshold and slope.
The fix should be in the next beta release, possibly as early as this coming
week.
Prior to this fix, as some K4 users observed, the max
After exchanging emails with N4ZR, who started this thread, we think
this is the easiest procedure:
Tune the rig to 10.000 MHz in CW mode. Listen to the tone of the WWV
carrier, which should be close to your CW PITCH setting.
Switch back and forth between reverse cw and normal cw, adjusting

It’s the bottom selection in the Mode menu. Shows your offset in Hz to about 5

Hi Wayne,
After searching I found info in the programmers manual that helped me
understand how it works. It is a little hard to follow using the K3 / K3S
owners manual, and / or Cady’s book.
I have written a couple of macros, not yet checked out, that may work(?).

You're correct - it hasn't been stated anywhere but that won't stop some
from refuting it as if it were ;-)

I agree. I never said, believed or thought an NVIS antenna HAD to be low, I
just said it COULD be low.
In fact I was banking on the fact that making it low would make distant signals
weaker. ;-)

Just a comment on low dipoles:
On the Iditarod Dog Sled Race (Alaska) we had ham stations located in
remote located checkpoints (total bush-no telephone or other utilities).
We used 80m and 40m to communicate with race HQ in Anchorage over
paths of a couple hundred miles to 600 miles, or so.
The method I use seems to work great and be easy enough to do. No zero
beating required and no external measurements required.
Put the radio in CW mode, tune to a WWV frequency and press and release
SPOT. The radio will automatically zero to the carrier with a tone that
matches your
NVIS information is almost always anecdotal and a myth, more than science!

lowering your antenna will make your signal stronger, expect your QSL cards
to arrive on a unicorn." How many of you looked at Jim's, K9YC,

I'm about 25 km LOS from W7RN. W7RN is 30 over S9 here on 160, 10 over
on 80, about S7 on 40 anytime. I can barely see it on the P3 [and it's

My K2 PLL problems all originated in one inadequately tinned toroid wire. I
have successfully built a fair number of kits with toroids, but it is pretty
easy to end up with a lead that is not actually connected. Even though it looks
good.
So that is where I would start, check for continuity on

way toward limiting the contacts you make to NVIS propagation.
I suspect you could accomplish the same result simply by reducing
transmitter power.

That's a great suggestion.
Those are correct who say that an antenna (dipole) doesn't have to be low
to the ground to make use of NVIS - but having a low antenna goes a long

Having trouble setting TX-EQ for FM and SSB. Changing TX EQ when setting TX EQ
in FM mode, the TX EQ setting for SSB changes to what was set when in the FM
mode. This feature appears to not be working.
Manual says two separate EQ settins are available ,, one for SSB, a second for

For 80M NVIS I put up a 'improved' extended double Zepp (315' long
designed by N6LF) at 30' with a wire reflector 5% longer buried an inch
in the ground. There is a 4:1 balun at the center with a coax feedline
to the shack. Covers entire band under 2:1 SWR. Email for more details
if desired.
I put up an NVIS antenna for 80m a number of years ago. It works great
for local 80m nets.
It is a full wave length loop (more square) mounted about 10' above the
ground.
It is feed with 450 ohm ladderline from a 1:1 current balun at the ATU.
EZNEC shows the radiation is UP.
It also shows gain
