Re: [Elecraft] Utilities on Linux

[TL_Netvision]

Yes I do the same + I try a "save config." B4 I upgrade anything. 

Unfortunately my P3 probably needs a trip to California before any firmware
from any version of the utility on any architecture can be uploaded to it.  
As usual Tech support has been fantastic  - it's the findings I don't
like...hihi

When I download new firmware for either the K3 or P3, I place it its own
directory which I create through the Browse button in the top part of
the Firmware tab.

Then work through the utility starting with the Port tab and the Test
Communications button to ensure you have communication to the P3.  The
latest stable P3 firmware appears to be 1.60.

Re: [Elecraft] KX2/KX3 operating tip: Creating a CW "sound stage" using AFX PITCH mode

[Grant Youngman]

That would be a very good thing, especially if the midpoint of the soundstage 
followed the Pitch setting.

When wearing headphones, it would also be less tiring to use if the soundstage 
had some “spaciousness” to it rather than signals appearing on a simple 
straight line inside the skull from from one eardrum to the other.  I don’t 
know how to describe this technically, although I know it when I hear it.  The 
existing AFX options in the K3 provide something close, as does the Delay 
option on the KX3.

Re: [Elecraft] KX2/KX3 operating tip: Creating a CW "sound stage" using AFX PITCH mode

[Wayne Burdick]

Hi Randy,

PITCH mode is not available on the K3 at this time. It was a bit of an 
experiment when we added it to the KX3 (which uses a different DSP chip). We 
liked it, and kept it. 

It's on the list for future addition to the K3/K3S.

Hmmm... My K3S has Firmware V5.62 (latest production) installed. As 
describedin the latest available version of the K3S manual, the only AFX 
MODE settings are DELAY 1 through DELAY 5 and BIN. PITCH is not an

Hi all,

The KX3 has two different AFX (audio effects) modes: DELAY (simulated stereo) 
and PITCH (binaural pitch mapping). DELAY is the default, and it can greatly 
reduce operating fatigue as compared to mono audio.

PITCH is sometimes overlooked as an option, but it too can make listening more 
enjoyable. Especially on a busy CW band segment.

When AFX is set to PITCH, all of the signals in the passband will be "mapped" 
into a left-to-right acoustic space based on their pitch. Lower-pitched signals map to 
the left, higher pitches to the right.

We describe it as a "sound stage" because it's similar to what you hear in a 
theater when there are multiple voices or musical instruments. With each signal occupying 
its own binaural niche, it's easier to pick them out and to recognize them. This can be 
very useful in contests, on nets, or when working DX split.

I have the same issue with most Elecraft and other ham-related programs when
using Norton. The files get quarantined after downloading because they're
'suspect", typically due to "few users". There should be a setting in your
anti-virus program to get the file restored and "ignored" or "allowed".

Re: [Elecraft] New KPA1500 Remote Program

[Eric Swartz - WA6HHQ, Elecraft]

We do not see any virus violations here when installing the latest version of 
KPA1500 Remote on our W10 or Windows 8 machines. I'm using it to control the 
KPA1500 amp at my home station from work.


Of course it always asks you to confirm first before allowing installation.

Re: [Elecraft] CW Transmit Filter Bandwidth

[Don Wilhelm]

Byron,

You are assuming that the CW signal shape is controlled by the TX filter.
It is not - that is done in the DSP and produces a clean single 
frequency signal that is quite good at TX phase noise and keying artifacts.
As long as that signal fits within the bandpass of the filter all will 
be well.  In other words, a 1kHz filter would not produce an improvement.


It might with some other rigs, but not with the K3/K3S because the 
filter is not the limiting factor - the DSP shaping and the low TX phase 
noise of the K3/K3S are the determining factors.

Obviously, not as a factory default, since only one filter is sure to 
be there, but on a per-user basis.


I thought years ago (before I had Elecraft) I read that a narrower TX 
signal made for a stronger signal within that narrower bandwidth.

Re: [Elecraft] KX3 DX

Strange, cranking up the compression doesn't seem to be affecting my 5 watt CW

In keeping with the discussion, I use a small amount of compression and no TX 
equalization on SSB and have had good success and audio compliments at 10 watts.

Re: [Elecraft] CW Transmit Filter Bandwidth

[Walter Underwood]

As I understand it, the K3 generates a very clean CW signal with DSP. There 
isn’t anything to filter out.

A narrow filter might add distortion and make things worse.

Re: [Elecraft] KAT100 - Reluctant to come on, K2 often displays "not inst"

[Don Wilhelm]

Bill,

The AUXBUS is NOT at fault.
The parts to concentrate on are shown in the lower left corner of sheet 
2 of the KAT100 manual.  Something there is not working reliably.  My 
first guess would be Q2, but it could be something else associated.


That entire powering circuit is controlled only by the 12CTRL signal 
from the K2.


73,
Don W3FPR

On 8/19/2018 9:32 PM, Bill Coleman wrote:

OK. I could use a little more help with this issue.

Let’s re-cap where we are.

Issue:

KAT100 doesn’t always turn on right away. When it does this, it may or may not 
switch low/high power LEDs when the power control is rotated. Pressing Ant 1/2 
or Tune, the K2 will indicate “not inst”. Sometimes it will power up just fine.

Observations:

- If powered on incorrectly, the KAT100 never “recovers” — if the K2 doesn’t 
see the KAT100 at power up, it never discovers it.

- Generally fails when unit is cold / not used in a while, will eventually work 
if turned and left on for several hours, then switched off and back on.

- KAT100 is receiving power before the K2 is switched on. When the K2 is 
switched on the 12CTRL line on J3 pin 8 comes up immediately, and the 5V output 
from U8 does as well. So, power is immediately available when the K2 is 
switched on

- When the KAT100 works, the ANT 1/2 and Low / High Power LEDs light 
immediately on power-on.

- When the KAT100 fails, the ANT 1/2 and Low / High Power LEDs stay dark for a 
second or so, sometimes a few seconds

- AUXBUS transitions are coming in on J3 pin 6 and make it all the way to U1 
Pin 40.

- I have two different interconnect cables. One is a three-way cable built 
exactly to the KAT100 specs, complete with jackscrews. The other is a simple 
two-way cable that connects Pin 1 and Pin 6-9 straight through with no 
jackscrews. Failure occurs with either cable.

- I have reseated the U1 chip in its socket with no change in behavior.

My current working theory is that there’s something in the KAT100 that prevents 
the U1 chip from resetting quickly. If it comes up immediately, the LEDs light 
and the K2 catches the unit during initialization. If its sleepy and doesn’t 
come up right away, it misses the opportunity to initialize and the K2 doesn’t 
know it is there. I think the antenna tuner and the low/high power indication 
are done in two separate initialization steps, because sometimes the KAT100 
will respond to turning the power knob, and sometimes it won’t when the Ant 1/2 
/ Tune always responds with “not inst”.

Nothing else in the K2 apparently suffers from any AUXBUS failures, all the 
other units - SSB, NB, DSP, KPA100 always come up right away. This makes me 
think the issue isn’t with the K2, but perhaps with the KAT100 alone.

Anyone have suggestions? I’d really like to make my K2/100 with KAT100 a 
reliable rig again. I don’t want to have to power it up a day before I want to 
use it.

Re: [Elecraft] KPA-1500 PSU mounting position

[Don Wilhelm]

Peter,

If you mount the KPA1500 power supply vertically, put it on the front 
panel and there will be no interference with the air flow.
Note that the LEDs stick out a bit from the front panel, so put the 
large part of the front panel on something that will be as thick or 
thicker than the amount the LEDs project - like a piece of wood or plastic.

untis, or can the power supply actually be run vertically with equal efficiency
and cooling as it would be horizontally? If so, that would fit my operating desk
perfectly.

Re: [Elecraft] VOX Sensitivity for K2

[Don Wilhelm]

Ted,

Which Heil Proset are you using?  There are basicly two types - those 
with an electret mic element and those with a dynamic mic element.  The 
Proset-K2 and the Proset-iC have electret mics while the others have the 
dynamic.  Look at the pivot button for the microphone arm to see which 
type you have.


Your setting is usually fine for the dynamic microphones, but with the 
electret mics usually only need SSBA set to 1.

This is the same sort of argument that some folks in the Emergency
Management community raise - why do we need radios when we have cell
phones and the internet.  That assumes that the internet and the
cell-phone infrastructure that depends on same will exist when the chips
are down.

I remember being in the studios of a major AM radio station when the
corporate auditor told the chief engineer "this could be a very
profitable operation if we could get rid of this thing called the
transmitter".  (Rest in peace, Howie)

I would suspect that the incremental cost of running WWV and WWVH -
which are mostly "set and forget" operations - is of the same order of
magnitude as the paper towel and toilet paper bill for that agency.

Re: [Elecraft] KPA-1500 questions and low pass filters

[Hisashi T Fujinaka]

I had similar questions.

Use a cable with RCA jacks to connect the K3/K3S rear panel 12V DC OUT
RCA connector to the KPA1500 REM RCA connector to wake it up. You'll
still need something to change OPERATE/STANDBY on the KPA1500, but I
just use the KPA1500 utility over Ethernet.

The power output on your K3/K3S will be different when you have the amp
in OPERATE or STANDBY.

Hi all,
Just got my 1500 connected last night and so far so good. I do have two
questions, however. First, is it possible to toggle standby and operate from the
K3s, instead of using either the remote software or physically pressing the
button on the amp? And second, I was under the impression that there was a way
to have separate transmitter powers depending on whether the amp is inline or
not. I normally like to run the full 100W from the K3s, but when I kick the amp
in, I have to drop TX power to ~25 Watts.

Another issue I have involves the feed path. I am using a remote antenna switch
mounted at the tower. At the moment I have all my HF antennas connected through
there, using the Antenna 1 port on the amp (previously on the K3s). Antenna 2 is
for 6m only. I would like to route the 6m antenna from this switchbox as well,
but the problem is the HF output is running through a low-pass filter. Are there
low-pass filters that don't cut off until ~54 MHz?

Peter Dougherty

Re: [Elecraft] KPA-1500 questions and low pass filters

[Don Butler]

Peter, I’m not completely sure because I have my amp in the shack within reach, 
but I think you’ll need to switch in and out of standby from the amp itself 
(unless you’re using remote software) …. But regarding the second question, if 
you have selected “power per band” from the K3s menu, and if you have the rig 
and KPA1500 connected with the auxiliary cable, the K3s power settings will 
follow the oper/stby selection on the amplifier…. And will be specific for each 
band.   When you switch into standby, the K3s will switch to the barefoot power 
of your choice (100W in your case) …. When you switch to operate, the K3s will 
drop to the drive power that had been selected the last time you used the 
amplifier on that band.
