Re: [Elecraft] KX3 and WSJT-X Setup

[Neil Zampella]

I've had WSJT-X working with my KX3 for over two years now. I realize 
that you already have the Signallink, but try going directly to the PC 
instead and see if that fixes anything.


All you need is:
1.   KXUSB cable for CAT control
2.   Two stereo audio cables for audio in and out.  I bought the KX3 
cable kit as it comes with all the cables needed for hookup of the KX3 
to most anything.


Turn off any system sounds going to the PC soundcard, and see if that helps.

I use an external SoundBlaster USB soundcard and have never had a 
problem with needing any sort of audio isolation.

I'm not finding the correct settings for it to work right. I can get it to
decode sometimes. I can get the KX3 to transmit but I really do not think
it is transmitting because when I try WSPR, it does not show me receiving
anyone or anyone receiving my signal. With Windows it was easy, just set
the input and output to CODEC and Applications at 50% and it worked great.
I am having trouble finding the settings for the KX3, Signalink, and WSJT-X
to all work together.

Re: [Elecraft] Using DX4WIN as P3 RTTY Data Terminal

[Joe Subich, W4TV]

Can a program like DX4Win simply act as a Data Terminal to the P3?

It *can* but DX4Win dos not provide that capability.


I know you need a communication package connected to the P3 for it to
accept commands, like KY and Transmit, so I wonder how to get them
both on the COM port unless DX4Win is the hub.


The application (e.g., DX4Win) needs to multiplex its radio control
commands with the KY; command on transmit and poll for received text
(TB; command) on receive.

Win4K3Suite and DXLab Suite (DXKeeper, Commander and WinWarbler) are
the only two (Windows based) applications that support both control
of the K3/K3S/KX3/KX2 and the P3 "Terminal mode" as far as I know.

Re: [Elecraft] OT: USB and LSB - How we got there

[donovanf]

Ian's posting is correct. 


A popular method of generating SSB in the late 1940s used a 5 MHz 
SSB generator mixed with a 9 MHz VFO producing a USB signal at 
14 MHz and a LSB signal at 4 MHz. 


See "On the Air with Single Sideband" December 1949 QST 
page 58 (lower right hand corner).

Re: [Elecraft] KPA1500 duty cycle

Hi Erik,

Yes, the amp can run indefinitely on 50 Mhz with 50 sec key down TX at 
continuous 1500W carrier followed by 50 sec in RX. We specifically were looking 
at 100% carrier modes like JT65 etc. when we conservatively specified this.

50 sec standby (Rec. Min Fan Speed set = 2)".

My question: For the 50 MHz scenario of alternating 50 sec carrier and 50
sec standby, how much testing has been done? Has anyone run this way for
days on end?

What's your objective?  Casual ragchewing?  Working a DX station?  
Contesting?  For the first two, the P3/SVGA approach is fine. Much less 
so for contesting -- for that, you want MMTTY or 2Tone and a contest 
logger like N1MM.


FWIW, FT8 has put a big dent in casual PSK and RTTY operation, and for 
that, you need WSJT-X and a couple of audio cables.

Re: [Elecraft] SP-3 frequency range question

[Don Wilhelm]

Chuck,

With only 100mW of audio from the KX3 phones jack, I doubt the KX3 will 
drive any speaker directly.  Use amplified speakers.

The SP3 will work fine if you add an amplifier.

I use the West Mountain Radio ComSpeakers with my KX3.  They are not 
only amplified, but are shielded for RF immunity.  No problems here with 
output at 100 watts (I don't run more than that here, never have).

I've been using the Pyle PCB3 series "cube" speakers since well
before the SP3 was introduced.  The Pyle speakers are spec'd at
90 - 20 KHz (about the same as the SP3) and are easy to drive
as well.

I notice no difference in response between the speakers and my
headphones (typically Yamaha CM500 but occasionally smaller,
ear bud or "professional" Sony headphones) *HOWEVER* I have the
K3 RX EQ set to roll off (-16 dB) the 50 and 100 Hz bands with
a -6 dB roll off in the 200 Hz band for SSB/AM and with -16 dB
at 50 Hz and -3 dB at 200 Hz for CW.

There is no issue for me with the roll off if/when I listen to
AM or shortwave broadcast but I can certainly "flatten out" the
response by changing the RX EQ to flat or even add a bit of low
end boost if band conditions are quiet/no QRM.

In the real world, does the SP-3 exhibit well rounded frequency
response? Or, is the response more directed for "communications use"?
How is it for listening to AM broadcast? How does it do with the famous
K3 hiss? How does it do with a less capable receiver (one without an EQ)?
I am considering some station simplification, hence the SP-3. Currently,
I am using the Behringer MS40 pair. Super sound, but quite large and do
have an internal amp (I have experienced no RF problems).

Re: [Elecraft] OT: USB and LSB - How we got there

[Don Wilhelm]

Ken and all,

BUT, that information is incorrect.  The sidebands will NOT invert with 
a 9 MHz IF and a 5 MHz VFO.


A little simple math should convince you.
Assume a 9.000 MHz IF and a 5.200 MHz VFO and a modulating frequency of 
1kHz.


9.000 + 5.200 = 14.200 for the carrier frequency
9.001 + 5.200 = 14.201 for the modulated frequency.  That is Upper Sideband.

9.000 - 5.200 = 3.800 for the carrier frequency
9.001 - 5.200 = 3.800 for the modulated frequency - that is also USB.

The early SSB generators (Central Electronics 10A for one) did use a 9 
MHz SSB generator frequency, but there was a switch to change sidebands.


If you have a 5 MHz IF with a 9MHz VFO as was used by Hallicrafters, the 
sidebands will invert between 75 and 20 meters.  Try the addition and 
subtraction to convince yourself.

Re: [Elecraft] OK, odd question

[Roy Koeppe]

It is the "custom" for CW mode to use LSB on the bands below 20 meters and 
CW USB on 20 meters and the bands above it.


Hiram Percey decided that long ago.

73,   Roy K6XK




I for one like the tuning direction of the Elecraft rigs in CW (LSB).
When I began ham radio using much older receivers, I liked listening
with the BFO set to LSB.  My perception was "If the pitch goes up, I am
tuning to a higher frequency".  Those receivers did not have very good
frequency resolution and it helped me in tuning correctly.

I realize that is my preference, others like it the other way around.
It is easy to set the Elecraft gear to CW reverse, and that is "sticky",
so you only have to change it once for each band.

It is a designer's choice, so I guess Wayne agrees with me because he
made LSB CW the default.

Re: [Elecraft] OT: USB and LSB - How we got there

[Alan]

It amazes me that there is still so much confusion and misinformation 
about something so simple.  There are two ways to get 80 meters (3.5-4 
MHz) and 20 meters (14-14.5 MHz) using a single VFO and IF:


9 MHz IF, 5-5.5 MHz VFO:

   - Sideband direction is the same on both bands
   - VFO tuning direction is inverted on 80, non-inverted on 20

5.25 MHz IF, 8.75-9.25 MHz VFO:

   - Sideband direction is inverted on 80, non-inverted on 20
   - VFO tuning direction is the same on both bands

So the convention about using LSB on the low bands and USB on the high 
bands has nothing to do with a 9 MHz IF.  It may have to do with using a 
5.25 MHz IF and a VFO centered on 9 MHz.

[Elecraft] OT: USB and LSB - How we got there

[Ken G Kopp]

Here's a URL to a website with lots of information:

http://www.ac6v.com/73.htm#LSB

Or, search "BC-458 command set transmitter" and
"Central Electronics 10A" with your browser.

73!

[Elecraft] KPA1500 duty cycle

[Erik Basilier]

A recent Elecraft newsletter stated that "the KPA1500 is a high duty cycle
amplifier compatible with most digital modes ranging from RTTY through JT65
etc.". The KPA1500 manual specifices  for 50 MHz "Maximum 50 sec key down /
50 sec standby (Rec. Min Fan Speed set = 2)".

My question: For the 50 MHz scenario of alternating 50 sec carrier and 50
sec standby, how much testing has been done? Has anyone run this way for
days on end?

73,
Erik K7TV

Re: [Elecraft] OK, odd question

[Buck]

I find it helpful to tune from a high pitch to a low pitch.  That way, I 
hear the signal coming rather than have it sneak up behind me and tune 
past the optimum tone.  That means, I have to shift the Reverse function 
depending on whether I am tuning up or down in frequency.

I realize that is my preference, others like it the other way around. It 
is easy to set the Elecraft gear to CW reverse, and that is "sticky", so 
you only have to change it once for each band.


It is a designer's choice, so I guess Wayne agrees with me because he

Re: [Elecraft] OK, odd question

IIRC there was no "standard". It was an arbitrary choice by the manufacturer
which side of the filter they put the BFO crystal frequency. Nice to have a
choice with the K3!

God bless Madelyn.  She has the patience of a saint.  I was struggling to
understand what was included in one of the package deals, so she actually
screen-shotted me exactly what I needed to get an order together with all
the options, making it so much easier for me to click through and verify I
had everything ready to go before I hit the "buy" button.

Great customer service, as per the usual Elecraft standard.

Re: [Elecraft] KX3 and WSJT-X Setup

[Brian P]

I dont have a KX3 yet (still in the market and saving for one) so I am not
sure if its something KX3 related or not and I am also not sure how you
installed WSJT-X (from the Linux Mint Repo or compiled from source) but
something you can check to make sure it is configured correctly for your
system, as WSJT-X requires 16 bit audio at a 48 kHz sample rate and the
default Pulse Audio setting is normally 44.1 Khz so the easiest way to make
sure this is configured correctly is to copy the file /etc/pulse/daemon.conf
to $HOME/.pulse/daemon.conf and modify the version in your home directory.

Find the line ; default-sample-rate = 44100 toward the end of the file,
delete the leading semicolon and space and then change the value to 48000.
It should now look like this:

default-sample-rate = 48000

Save the file, then reboot the entire system to ensure Pulse Audio restarts
and grabs the updated settings and see if that helps you at all.

[Elecraft] KX3 and WSJT-X Setup

[Aaron K5ATG]

I am having a little trouble here. I have a KX3 that I'm trying to setup
for FT8 using WSJT-X v1.8.0. I'm using a Signalink USB. My operating system
is Linux Mint 18.3
I'm not finding the correct settings for it to work right. I can get it to
decode sometimes. I can get the KX3 to transmit but I really do not think
it is transmitting because when I try WSPR, it does not show me receiving
anyone or anyone receiving my signal. With Windows it was easy, just set
the input and output to CODEC and Applications at 50% and it worked great.
I am having trouble finding the settings for the KX3, Signalink, and WSJT-X
to all work together.
