Re: [Elecraft] [KX3] KX3 Beta firmware rev 1.48: Adjustable noise blanker level

[AC6JA]

The ability of the "sticky" feature to keep the NB enabled when switching  
bands is worth the price of admition alone! 
Thanks for the upgrade!

KX3 beta firmware rev 1.48 (with DSP  rev 1.20) is now available. See

You'll need the KX3 Utility application to  download and install firmware. 
For full instructions on loading beta releases,  refer to our KX3 software 
page:

http://www.elecraft.com/KX3/KX3_software.htm

DETAILS:   


The KX3's noise blanking level can now be  set using the knob above the NB 
switch (AF/RF-SQL). When NB is turned on (by  HOLDing the NB switch), the 
present setting (1-15) will be displayed on VFO B  for about 3 seconds. To 
select a new setting, rotate the knob before the  display times out. The 
display will then persist until you tap any switch. A  subsequent hold of NB 
will 
turn the NB off.


The NB setting is stored per-band, as is the NB's  on/off state.

Important  notes: 

-  The noise blanker is intended to reduce the amplitude of repetitive 
pulse  noise with a fast rise time. It will not suppress atmospheric noise. For 
that,  you may want to try NR (noise reduction). 

- Noise blankers will cause a certain amount of  intermod or shaping of 
signals when set too aggressively. We minimized this  with our new DSP 
algorithms, but you'll still want to use the lowest effective  setting. "NB 1" 
will 
do the least blanking and create essentially no  artifacts. Settings up 
through "NB 8" or so will still minimize artifacts. If  the noise is really 
strong, you can go all the way up to 15. These higher  settings are great for 
digging out weak signals, but can modify the sound of  strong signals somewhat 
and cause some pumping on a busy band.

[Elecraft] [K3] Swap - 8 Pole Filters for a KBPF3 + MH2

[Jeff Cochrane]

G'day everyone,
I have available 2 x 8 pole filters for a K3, they are the  KFL3A-2.1K & the
KFL3A-250.

I'd like to swap them for a KBPF3  General Coverage RX Bandpass Module + a
MH2  Hand Microphone.

Please reply off list with offers,

Thanks in advance.

Re: [Elecraft] KX3 noise blanker (NB) level now adjustable -- need testers

[Dave Jones]

Hi Wayne

The firmware loaded ok here using the new KX3 utility. The noise I reported 
yesterday (plasma??) was still on 80 & 40 and I was able to confirm that the 
noise blanker did at least remove much of the pulse content of the noise with a 
setting of between 10 and 12. Unfortunately there was no activity on those bands 
at the time so I was unable to see what effect the NB had on the received speach 
quality. As luck would have it last night and this morning 80 & 40 were both 
quiet QRM wise although what pulse noise was apparent in amongst the atmospheric 
noise was eliminated by the NB at a setting of around 7-8.
I checked for the reported error message when recalling a stored frequency but 
that was unable to replicate it either with the RCL or STORE functions.

Looking good!
73 Dave VK4FD

path for lightning instead of allowing it to punch a hole in your 
building foundation.


I would also suggest at least 3 radial wires from the tower (length at 
least 1/2 the tower height) with driven ground rods spaced twice the 
length of the ground rod.


I like this advice, BUT -- also make sure that ALL other grounds are 
also bonded to this ground. That includes the common connection of all 
the gear in your shack (which should have a bond from one chassis to 
another for each piece of gear), the antenna entry point, cable TV 
system, telephone system, cold water (it it's metallic), structural 
steel if there is any, and the green wires for all the outlets in your 
shack.


A quibble though -- the "green wires" for all the outlets must be bonded 
to the enclosure of the main breaker panel, and they MUST be connected 
to your gear via the power cord. That combination of wires IS a 
connection through the house, although it's not a very good one, both 
because the conductors are small and they're long, so they're inductive. 
SO -- my advice, and what I've done in MY shack (where power is on one 
side of the building and the shack is on the other), is to do BOTH the 
perimeter wire (#4) with rods at multiple points along the run, and 
bonding the steel conduit (EMT) that carries wiring for the shack to the 
operating desk common point, and to the coax entry point.


The fundamental concept is that you want to provide a robust, short path 
to earth for the strike (which can come in on your antennas, the tower, 
a phone line, a CATV cable, the power line, and even the wiring inside 
your home), and for everything in your premises to stay as close to the 
same potential as possible. To accomplish that, you want multiple paths 
to earth (ideally close to every entry point), and the lowest possible 
IMPEDANCE between everything in the premises, with conductors large 
enough that they can carry as much current as practical before they 
melt. :)  Because lightning is an RF event, with a very broad energy 
peak around 1 MHz, the impedance is mainly INDUCTANCE, not resistance, 
which is why "short" matters, and why more parallel inductors are better 
than one.

Re: [Elecraft] [K3} CW in SSB - no manual PTT?

Neither - it is a feature.  Activating PTT activate SSB mode when in
SSB.

[1] In CONFIG - CW WGHT, tap 1 for SSB + CW (allows CW in SSB modes).
The problem is independent of other options within this menu. It has

wouldn't you get microphone audio mixed with the CW tone if you'd

Re: [Elecraft] KAT3 use in multi-transmitter environment

[Ian Kahn]

Bill,

My club (North Fulton Amateur Radio League in Roswell, GA) has had K3s with
the KAT100 at Field Day for the last several years.  We've never had issues
with other stations' transmissions triggering tuning on the K3.  In fact,
we've had really good success using the K3 in Field Day situations with
little to no issue whatsoever.  The only time we had interference issues,
our CW station's antenna was pointed right at the antenna used by the K3.
I don't think any amount of filtering (even on the K3) would solve that
issue.  :-)

73 and good luck!

Correct - but (key_down .and. PTT) is unambiguous.

Re: [Elecraft] [K3} CW in SSB - no manual PTT?

[iain macdonnell - N6ML]

Hi Ian,

What you describe is how I understand it's supposed to work. If you
assert PTT in SSB mode, it's assumed that you want to transmit SSB.
The firmware has no way of distinguishing "SSB PTT" from "CW PTT".

73,

~iain / N6ML

Re: [Elecraft] [K3} CW in SSB - no manual PTT?

[Ian White]

Microphone muting is not a problem. When SSB VOX and CW VOX are both
enabled, we can hear the CW-in-SSB logic working correctly: whichever
mode of transmission is triggered first, that mode "wins" and input for
the other mode remains muted until the VOX drops out. 

The problem specifically involves the use of manual PTT (microphone
button, XMIT button or foot switch) which completely blocks the CW
input.

Re: [Elecraft] KAT3 use in multi-transmitter environment

Bill,

There should be no problems of that nature.  The KAT3 does not sense RF 
to tune.

[Elecraft] FS: KDSP2

[Bartek SQ5OBP]

FS KDSP2 built last year, working as advertised, solded using rosin-core
solder.
Will ship in anti-static bag and include manual and a box.
Please note that two female headers (Ctrl-J2 and Ctrl-J1, 3- and 5-pin
respectively) have been installed on the Control Board and will not be
provided. Original 4-40x1/4" screw has been lost. You'd have to get these
from an other source. Hex spacer and CR-2032 cell will be included.

Price: $240 + shipping. Shipment costs around $15 depending on world region.
Paypal is the only payment option.

Please reply off list.

[Elecraft] [K3} CW in SSB - no manual PTT?

[Ian White]

When using the "CW in SSB" feature [1] my K3 will transmit CW using semi
or full breakin, but not when using manual PTT. The footswitch and the
XMIT button will switch the K3 into transmit, but then the CW keying is
blocked.
 
Is this a configuration error on my part, or a firmware bug? 


[1] In CONFIG - CW WGHT, tap 1 for SSB + CW (allows CW in SSB modes).
The problem is independent of other options within this menu. It has
also been around for a long time.

Re: [Elecraft] [K3] Internal 2M transverter vs. 10M beacon

[Peter Eijlander (PA0PJE)]

Dennis, are you sure you do not mistake this for 28MHz feedthrough?
The transverter in the K3 converts 144 MHz to 28MHz. There is no 
harmonic relation to 144.302 and yes... 10 Watts on 10 meters 15 meters 
apart from an HF receiving antenna will no doubt leak through.

Are you sure the 116 MHz transverter crystal is calibrated properly?


Dennis Ashworth schreef:

I run a 10 watt beacon on 28.2985. Tuning across 144.302 (K3 + internal
