[Elecraft] K2 VFO/ALC issues

[Mike Short]

I recently bought a used K2/10 and the S-Meter does not work. I am looking
at the K2 VFO/ALC mod and have a question about the 1N4148s that are added
to Q18.

This one has a 1N4148 installed on the bottom of the board anode to cathode
across D13, and no diode from Q18-S to ground. Was the additional diode
part of another mod? Seems to me that it would defeat the purpose of D13.

Re: [Elecraft] Problem with K3 driving old tube amp

[Bob McGraw K4TAX]

Sounds as though ALC from the amp is causing the transceiver to step 
power.   One should NOT use ALC from the L-4B to the K3. The ALC circuit 
in the L-4B was designed for exciters which did not have precise power 
control.   The use of ALC to control power in this configuration is 
likely to cause rather poor sounding CW notes.    Yes, everything you 
describe points to an ALC issue with the amp.   WHOOP WHOOP WHOOP

I have a power/SWR meter between the K3 and the amp and it shows a low

The power meter between the K3 and the amp shows the power gradually 
increasing. As the K3 increases power out, the amp power out increases 
in a similar fashion.


I see no indication of oscillation. The power meters on the output 
side of the amp show no power when the amp is keyed but no RF is 
supplied. I placed a low-pass filter (41 MHz cutoff) between the K3 
and the amp to no effect.


I notice that if I send a series of Morse code characters such that 
the K3 transmit delay timer never times out, once the power ramps up 
to the set value, it remains solid until the timer expires - when I 
start transmitting again, the power step process repeats.


When I put the amp in Standby, the K3 functions normally.

This smells like an oscillation problem, but I see no evidence of one.

Any advice would be appreciated.

Thanks,

Re: [Elecraft] K3 PowerPole connector

[Bob McGraw K4TAX]

I suggest using automotive primary wire, #10 AWG for power cables.   It 
is stranded with much finer / smaller wire than THHN and is much more 
flexible than THHN.    It does correctly fit the 30 amp PowerPole 
connectors thus no splicing is needed or as suggested.


I also recommend not only correctly crimping the PowerPole pins but 
carefully flow solder into the sleeves.   Likewise on the other end, the 
correct size ring terminal should be used, crimped and soldered, for the 
power supply connections.


The transceiver power should come direct from the power supply, thus 
avoiding any DC distribution panels.

Re: [Elecraft] K3 PowerPole connector

[hawley, charles j jr]

I use #10 all copper which just fits the 30 amp if you twist them really 
neatly. It takes several tries to where no strands get away.
We might warn folks about the copper clad aluminum that’s going around if you

[Elecraft] Problem with K3 driving old tube amp

[William Stewart]

All,

I am trying to bring a Drake L-4B to life. I have done the power supply 
rebuild, the soft-start and other mods. I have also directly grounded 
the grids of the 3-500Zs (Eimac brand). In driving it with my K3 (SN 
51XX, software up to date) I find that the RF power stair-steps to the 
set power in a hesitating way over a few seconds. This happens sending 
Morse code or using the "Tune" button.


The supply voltage, as monitored on the K3 display, is at about 13.4 
volts when transmitting.


I have a power/SWR meter between the K3 and the amp and it shows a low 
SWR at all times, as does the K3 SWR meter.


The power meter between the K3 and the amp shows the power gradually 
increasing. As the K3 increases power out, the amp power out increases 
in a similar fashion.


I see no indication of oscillation. The power meters on the output side 
of the amp show no power when the amp is keyed but no RF is supplied. I 
placed a low-pass filter (41 MHz cutoff) between the K3 and the amp to 
no effect.


I notice that if I send a series of Morse code characters such that the 
K3 transmit delay timer never times out, once the power ramps up to the 
set value, it remains solid until the timer expires - when I start 
transmitting again, the power step process repeats.


When I put the amp in Standby, the K3 functions normally.

This smells like an oscillation problem, but I see no evidence of one.

Any advice would be appreciated.

[Elecraft] KPA-1500 great service

[N4ZR]

Thank you to Cody and Michelle for great support with a fault in the 
KPA-1500 low pass filter board.  Cody quickly diagnosed the problem and 
Michelle expedited shipment to me.  It's now up and running again.


It's the small things that impress - like including extra screws for the 
LPF board mounting and the bottom of the cabinet, plus extra zip-ties, 
just in case.


Only one quibble with the instructions - it is almost impossible to get 
the old LPF board out with the TX sampling BNC connector in place. 
Temporarily removing it made all the difference.

Re: [Elecraft] Handedness

OK. I realize this is tongue in cheek, but...

We can move the feet to the top, flip the display in its 
mounting, and flip all the buttons. All that is left is to 
change the labels on the panel and handle the complaints that 
the tuning knob, RTI etc. are in the wrong places. :-)

Re: [Elecraft] K4 Band Stacking Registers

[Martin Sole]

Thanks for that, guess I just missed that button amongst all the other 
eye candy :)

When you tap the MODE switch (above the VFO), a list of all primary modes and 
data modes comes up on screen. You can then select one. We'll also provide an 
alternative behavior for the MODE switch for ops who use only CW and SSB (for 
example): tapping MODE will just alternative among 2 or 3 specific modes. This 
will eliminate the need to tap the mode buttons on-screen.

The *hold* function of the MODE switch is "ALT", as on our other rigs. This 
alternates between USB and LSB, CW-normal/CW-reverse, AM/AM-sync, etc.

Each VFO has its own mode identifier. This clearly shows which mode you're in, 
including data submode (e.g. FSK-D).

Hi Dave,

Tapping BAND brings up a set of band-stacking switches on-screen, one for each 
band (including WARC bands), plus one for general coverage, one for 
transverters, and one for most-recently-used frequency memories.

The advantage of doing this on the LCD rather than with hard switches is that 
we can provide different arrangements depending on the operator's needs. For 
example, the op may want more transverter controls, may not use the WARC bands 
during contesting, or might prefer to dedicate one or more switches to specific 
frequencies. If a new band is allocated in the future -- perhaps limited to a 
subset of countries -- we'll be able to add it with a software update.

Band-stacking depth will be adjustable.

Can someone please give some insight on how the band button below the K4 screen 
works and its capabilities?

Re: [Elecraft] The K4's new noise reduction

Message-ID: <8fb0faf5-8c7d-4e22-bbd5-4a06982e5...@elecraft.com>
Content-Type: text/plain; charset=us-ascii

We've recently started testing a new DSP NR (noise reduction) 
algorithm for the K4. Our early testers are saying it's as good or 
better than anything else they've used, removing stochastic noise 
without the characteristic "hollow" sound of earlier algorithms. In 
my own tests, I'm finding weak SSB signals I simply couldn't copy 
without it. It goes beyond just reducing listening fatigue. This type 
of NR operates in the frequency domain, like spectral subtraction, 
but without the usual artifacts (musical tones) or long sampling delays.


Once the full implementation is complete, we'll post audio samples 
and additional details.


(In answer to the inevitable question:  Unfortunately, we won't be 
able to port this to the K3/K3S. The new algorithm requires the new, 
much faster DSP chip we're using in the K4.)

Re: [Elecraft] High Resolution K4 JPG/TIF?

[Brian Broggie]

Al, the ethernet port is, as you say, bi-directional. The K4 can
communicate with other K4's to control them, or it can be the radio under
external control by either another K4 or an app on an iPad or a PC.

As far as boot time duration I don't have a real answer for that yet.
Quicker than a tube rig is a pretty safe bet. ;).

Brian.

Re: [Elecraft] Elecraft] MFJ-1234?

[A Kiddoo]

I bought the MFJ-1234. Have connected it to FT-450. My KX3 will remain portable 
rig. The RigPi is 4 parts - Rpi, windkeyer card, audio card, and software. I 
now have it setup on a Rpi I already owned with generic USB audio dongle 
connected to headphone jack and mic on radio. Works fine. I don’t intend to use 
for CW so I will soon be listing my MFJ-1234 for sale on QRZ. I don’t need the 
data cable because audio from it is not processed and not acceptable for SSB. 
Software is excellent with low latency on CAT. Audio is carried via Mumble 
server which is pre-configured in software. You will need to download/setup the 
Mumble client for remote. So if you want to do SSB on the cheap- just buy the 
software. Very good docs at rigpi.net/help  which should 
answer most.

Re: [Elecraft] K3 PowerPole connector - more info

[Rick WA6NHC]

I suggest that you also get Marine/RV wire as it is more flexible and 
easier to route neatly compared to the usual wire used (for the same 
size/rating).  Powerwerx may sell that, ask.


And that you go up one more size of wire to lower IR^2 loss, just because.

Re: [Elecraft] Handedness

Also being left handed, I've used the K3 on both sides, but prefer the 
radio on the left, leaving the traditional 'mouse' hand on the right; 
useful for those who can still manage more than one task at a time. ;-)


In other words, the K3 has no bias towards either hand for the essential 
controls.

[Elecraft] Additional K4 Questions for Now

[dhhdeh]

Hi Wayne,

Thank you for responding to my questions of earlier today.  I have 
several more of a secondary nature to ask for now. Thanks for taking the 
time.


-Will the shift/width and lo cut/hi cut functions be on the K4 similar 
as with the K3,  or does the nature of the direct sampling IF 
architecture make that no longer available?


-I notice a CW APF circuit is installed. Is it a variable width and how 
is that performed?


-Is the screen exclusively a touch screen or can screen functions also 
be mouse controlled?


-Does the DVR permit recorded QSO playback over the air as with the K3?

-Any estimate as to when a user manual will become available to study?

All for now. Again my thanks.

Re: [Elecraft] The K4's new noise reduction

[Drew AF2Z]

I'm fairly happy with my K3's NR/NB. I could always use more and better 
NR, or course, but a major negative for me is the long time it takes for 
the filter to rebuild when changing NR settings or WIDTH. I hope the K4 
will be speedier...

Subject: [Elecraft] The K4's new noise reduction

We've recently started testing a new DSP NR (noise reduction) 
algorithm for the K4. Our early testers are saying it's as good or 
better than anything else they've used, removing stochastic noise 
without the characteristic "hollow" sound of earlier algorithms. In 
my own tests, I'm finding weak SSB signals I simply couldn't copy 
without it. It goes beyond just reducing listening fatigue. This type 
of NR operates in the frequency domain, like spectral subtraction, 
but without the usual artifacts (musical tones) or long sampling delays.


Once the full implementation is complete, we'll post audio samples 
and additional details.


(In answer to the inevitable question:  Unfortunately, we won't be 
able to port this to the K3/K3S. The new algorithm requires the new, 
much faster DSP chip we're using in the K4.)

Re: [Elecraft] K3 PowerPole connector

[Don Wilhelm]

#10 or #8 wire will need the 45 amp contact blades.

However, if the purpose is to minimize voltage drop, there is no need to 
use the larger connector - construct the power pole with #12 wire about 
3 inches long.  Then splice onto that with #10 or #8 wire for the rest 
of the run to your power supply.

Are you replacing the connector that plugs into the K3 or are you

If the part that is built into the K3, I would strongly suggest  
getting the part direct from Elecraft.  These have to be securely  
mounted within the radio.


If the part that connects, note the following:

PowerPole connectors come in sizes according to the current amperage  
required for the particular circuit.


Anderson PowerPoles consist both of the red and black housing and the  
crimp connectors for the wires.


The housing size used in the K3 is the standard size that will fit  
both 15, 30 and 45 amp crimp connectors.   You choose the connector  
that fits the particular wire size.   30 amp capacity circuits are  
adequate to power the K3 and should be used.


Unless you purchase pre-assembled connectors you will also need a  
crimp tool to crimp the connectors to the wires.   There is also a  
small learning curve on how to crimp and insert the crimped wires into  
the housings.


I would get the parts you need from a company such as Powerwerx.  They  
can help with any connections.

Lee,

Unless you can be assured that they are genuine Anderson PowerPoles, I

higher current.


If they do not have a "A" embossed on the tip of the housing, they are 
not genuine.

Is there a way to transfer (copy) Macros from one K3 to a different one?  The 
only way as of now appears to be individually copy them from the Utility into 
Notepad (text file)macro by macro from the source K3 then to target K3 line by

Re: [Elecraft] K4 Band Stacking Registers

[Wayne Burdick]

When you tap the MODE switch (above the VFO), a list of all primary modes and 
data modes comes up on screen. You can then select one. We'll also provide an 
alternative behavior for the MODE switch for ops who use only CW and SSB (for 
example): tapping MODE will just alternative among 2 or 3 specific modes. This 
will eliminate the need to tap the mode buttons on-screen.

The *hold* function of the MODE switch is "ALT", as on our other rigs. This 
alternates between USB and LSB, CW-normal/CW-reverse, AM/AM-sync, etc.

Each VFO has its own mode identifier. This clearly shows which mode you're in, 
including data submode (e.g. FSK-D).

Re: [Elecraft] K4 VFO B Front Panel Positioning

[Wayne Burdick]

Dave,

Here's what I posted earlier:

* * *

Based in part on a survey of potential users, we chose to put the RIT/XIT knob 
at bottom right -- also a traditional location, one that matches that of the 
K3/K3S/KX2/KX3. VFO B is less often used in practice. That said, the radio is 
only 4.5" tall and both knobs are very comfortably used in these locations.

* * *

I use the K4 every day and find the control locations work well. Only a small 
adjustment in finger position is needed to move from VFO A to VFO B.

73,
Wayne

Re: [Elecraft] K4 Band Stacking Registers

[Wayne Burdick]

Hi Dave,

Tapping BAND brings up a set of band-stacking switches on-screen, one for each 
band (including WARC bands), plus one for general coverage, one for 
transverters, and one for most-recently-used frequency memories. 

The advantage of doing this on the LCD rather than with hard switches is that 
we can provide different arrangements depending on the operator's needs. For 
example, the op may want more transverter controls, may not use the WARC bands 
during contesting, or might prefer to dedicate one or more switches to specific 
frequencies. If a new band is allocated in the future -- perhaps limited to a 
subset of countries -- we'll be able to add it with a software update.

Band-stacking depth will be adjustable.

73,
Wayne

[Elecraft] K4 VFO B Front Panel Positioning

[dhhdeh]

I was not able to be at Dayton this year so I'm my initial K4 questions 
from pictures and videos seen online.


I'm wondering abut the positioning of the VFO B encoder in the K4. 
Wouldn't it seem more logical to have it where the OFS encoder is 
located than in the top right position where it is now? Seems to be a 
bit awkward to me.

[dhhdeh]

I owned a K3 from February 2008 until mid-2015.

One of the its UI features that I could never warm up to was the lack of

Can someone please give some insight on how the band button below the K4

Re: [Elecraft] Handedness

[George Thornton]

If Elecraft reflects things to get left hand orientation, does that mean all 
the letters on the front panel will be reversed?  Will lefties also need a 
mirror to read the labels?

Just a joke from a right hander.

Re: [Elecraft] K3 PowerPole connector

[George Thornton]

Are you replacing the connector that plugs into the K3 or are you replacing the 
part built in to the K3?

If the part that is built into the K3, I would strongly suggest getting the 
part direct from Elecraft.  These have to be securely mounted within the radio.

If the part that connects, note the following:

PowerPole connectors come in sizes according to the current amperage required 
for the particular circuit.

Anderson PowerPoles consist both of the red and black housing and the crimp 
connectors for the wires.  

The housing size used in the K3 is the standard size that will fit both 15, 30 
and 45 amp crimp connectors.   You choose the connector that fits the 
particular wire size.   30 amp capacity circuits are adequate to power the K3 
and should be used.

Unless you purchase pre-assembled connectors you will also need a crimp tool to 
crimp the connectors to the wires.   There is also a small learning curve on 
how to crimp and insert the crimped wires into the housings.  

I would get the parts you need from a company such as Powerwerx.  They can help 
with any connections.

Re: [Elecraft] Handedness

[Wayne Burdick]

Even in the case of the K3, the VFO and RIT controls are on the right side of 
center. In the K4, with its large display, there’s really no choice but to 
group the controls on one side or the other.

It is possible to invert the transceiver to favor left hand operation. A system 
of mirrors can then be used to restore panel text orientation.

[Elecraft] Apologies in advance for my sense of humor: "first to have 'Elecraft K4' on my desk"

[JK Hoop Hooper via Elecraft]

I couldn’t wait.   I had to have “Elecraft K4” on my desk.   

So I had a mouse pad made with the cover photo from the  K4 Brochure.   Not 
nearly the satisfaction that I’ll have at some distant point in the future when 
a real K4 graces my desk and ham shack, but, at least for now, I can say that I 
am among the first to have “Elecraft K4” on my desk.
