Re: [Elecraft] Dual Receiver Tricks

[Bob McGraw K4TAX]

Some years ago when operating HF packet in S. FL., I built an antenna 
switching arrangement which would take the error signal from my PK-232, 
count the errors and at some point switch to the other antenna.   One 
antenna was an 80M inverted V, the other was a Butternut vertical 
mounted over a salt water tidal canal.  I generally found when the 
signal faded, thus more errors, on one antenna the signal was stronger 
on the other.   The system switched antennas during the receive cycle. 
   I also incorporated a power control system which looked at each 
packet acknowledgement and would reduce TX power a small amount.  After 
a number N of missed acknowledgements it would increase power in small 
amounts.    It was nice to have a radio which I could control power by 
applying a few volts to the ALC input.


The aluminum Butternut vertical over tidal salt water presented one 
issue, which was the SWR changed multiple times per day as the tide 
cycle rise and fall.  The SWR change wasn't a lot but clearly noticeable 
a 3' to 5' tide change.  In effect the ground moved up and down, 
regardless of the amount of copper buried in the canal bottom.   I guess 
that stuff is still there as we moved away and left it in the canal.   
Oh, the Butternut is now located in my shop,  clean and ready to install 
again.   It has only been there 23 years and I still plan to get around 
to it.one of these days.


The things hams won't try and do.

Not sure what you are describing.  If you mean two antennas feeding two 
receivers at RF for diversity reception, yes ...  that works well but is not 
the same thing at all.  Your brain is doing some spatial processing, but it 
doesn't peak or null.  It also, as is apparent from the antennas you cite, 
compensates for polarization changes that would otherwise cause fading ... but 
it isn't peak/null.

If instead you are talking about being able to adjust phase and adding or 
subtracting the result, that can be done at RF but it definitely requires 
additional hardware.  You can't get there with just the K3 or K4 as is.

And none of what you describe would give you a numerical azimuth (or elevation) 
indication as the original post described.

Re: [Elecraft] Firmware Updates

[Don Wilhelm]

Bernie - and all,

I would suggest that you download and install the latest K3 Utility, 
then connect with your K3S and "Copy Files from Elecraft".


After that, look in the K3 Utility Help file for the Firmware Release Notes.

You will find information on the firmware updates between what you are 
now using and the latest.  If any are of interest to you, then update 
your K3S to the latest.  Simply click "Send All Firmware to the K3" and 
wait for it to complete (do not interrupt the process). It will take 
only 3 to 5 minutes.


I would encourage you to update the firmware as it is available.  It is 
much different than Windows Updates, and much less disruptive.  You have 
to initiate the update rather than having Microsoft, etc. deciding it 
"is good for you" and automatically installing.


In most all cases, the firmware updates are painless and take nothing 
away from your prior operation, but only add new features that may 
enhance your operating experience.


Should the very worst happen and your computer has a glitch during the 
update process, recovery is easy.  Just follow the instructions in the 
K3 Utility Help File for "Force a Firmware Download", and all will be 
well after that.
That problem rarely happens - computer power glitch, user interruption 
and other similar situations.  If it should occur for you, recovery is 
easy - just follow the directions.  I have only encountered it once in 
the 10 years I have had my K3 when I did "fumble fingers" to interrupt 
the total download.

I tend to go a couple+ years  between updating my K3 P3 KPA. Unlike MS, 
updating has never broken anything. I would do it without hesitation. And of 
course backup first. But I’ve never needed a backup.

Re: [Elecraft] Firmware Updates

[Bob McGraw K4TAX]

If you run the K3 Utility and the KPA500 Utility, download the latest 
from Elecraft and install same.  Also while you have those utilities up 
and running, do a back-up of each.  The current version for the 
KPA500 is 1.54 and for the K3S is 5.67 for the MCU.   I'd say both of 
your items are needing updated.


I get about 1 update per week from Microsoft and I have that installed 
at my choice...when I'm asleep.   Although I don't use it,  I'd also 
say that HRD is likely in need of updating as well.  I try to keep all 
of my software and systems updated. Things run much smoother in that regard.

Re: [Elecraft] Dual Receiver Tricks

[David Gilbert]

Over the past few years I have twice requested Elecraft include 
something like that as a software modification, but nobody (either at 
Elecraft or here on the list) seems interested in the least. Since phase 
is preserved during down conversion in a superhet circuit the software 
crunching could even be done at audio ... it isn't required to be done 
at RF.  It doesn't require the K4 either ... the K3 and K3s with the new 
synths also make it feasible.


In addition to simply determining signal direction, the software would 
potentially be able to equalize volume from the two receivers (generally 
required since typically two different antennas would be used) and then 
add or subtract the two signals to peak a desired signal or null an 
unwanted one.  The equalization could be done in software while the 
phase shifting would be manual and require a repurposing of a knob.  DX 
Engineering sells a stand alone unit for over $700 that performs these 
same functions at RF, while a software mod could do the same for free 
(to us ... obviously it would take a commitment of coding resources from 
Elecraft).


Elecraft has already said that they would at some indeterminate time in 
the future consider sanctioning well-chosen and trusted third party 
software developers for ancillary applications for the K4, but I'd like 
to see this capability for my K3 as well.


As an aside, it would theoretically be possible to investigate arrival 
angles using two horizontally polarized antennas placed one above the 
other a known distance apart.  At the least it might even allow a user 
to discriminate between two interfering signals from the same azimuth 
but arriving at different vertical angles.

Does Elecraft have plans to develop K4D software with such capabilities or
sanction 3rd party development of such?  Will there be other software /
firmware development to come with the K4D beyond that of a dual receiver
K3/s?

  


Lastly, beyond control and perhaps IF output, will the K4 receiver(s) be
able to interface with external 'computers?'  (No, I'm not sure what I mean
by that!)

[Elecraft] Firmware Updates

[Bernie and Cheryl]

I got my K3s (#10323) back in October, 2015, and got my KPA 500 (#2664) 
a few months later (I have the full K line including the KAT 500).


When I built them, I promptly updated the firmware, and haven't done it 
since.  I checked and my K3s has Firmware Version 5.35 and the KPA 500 
has Version 1.38.


Am I missing anything by not having updated?  I haven't done it because 
I am maddened by the constant crazy updates forced on us by Microsoft, 
Firefox, etc. (when I turn on my computer, I want to USE it - when I 
turn it off, I want it to shut off, rather than update for another 10-15 
minutes), and just hate updates in principal.  However, I noticed that 
the interface between the K3s and my Ham Radio Deluxe software is 
getting a little glitchy (sometimes, the software insists the radio 
isn't there, even though I've checked the cable), and I wonder if that 
is a function of needing to update things (and yes, I should probably 
update the Ham Radio Deluxe software).  This glitchyness is the only 
problem I experience, and otherwise, my setup works great.


Thoughts?  What am I missing?

[Elecraft] Comments from another 1st-time K4 op

[Wayne Burdick]

>From George, KJ6VU, at the Bay-Net FD operation:

* * *

The K4 was exactly what I expected to see.  The combination of my K3's great 
performance with super smooth CW keying and the P3 pan adapter all rolled into 
one.  It's great to see everything in a single package with a large display.  I 
am really excited to see the additional enhancements like CW, PSK, RTTY 
decoding on the same screen eventually.  The APF for peaking CW signals is 
amazing.  The front panel is very comfortable to use and having all these 
features in a single radio with this performance and yet not too heavy to take 
to the field is a real treat.

Re: [Elecraft] P3 Panadapter and non Elecraft transceivers

[Don Wilhelm]

Jim,

Refer to your Icom CT-9100 manual.
First thing to be determined is -- does it have an IF output?
If so, the 2nd thing to determine is -- What is the IF output frequency?

The P3 can be tuned to use an IF output between 455kHz and 21MHz.

If there is no IF output, then you would have to add one.  The Icom 
forums would be your best resource for the base way to add one.

So to make a long story short, the K3S will put out over 100 watts on 160 and 6 
meters if your power supply voltage is at 13.8 volts and you keep the power 
cord short. The additional 32" of power cord dropped the voltage by 1 volt on 
key down.

Everett,

What is your power supply voltage during transmit at 100 watts as measured
with the Alternate VFO B display?

With a solid 13.8 volt power supply voltage, you should see no lower than
12.7 volts (there is a diode drop inside the K3).

If lower, check the connections in the power cable for tightness.
The K3 power cable should run direct from the power supply.  Rigrunner and
other DC power distribution boxes can be reason for excessive voltage drop.

You can increase the power supply voltage up to above 14 volts to help - do
not exceed 15 volts.

Re: [Elecraft] QRP FD KX2 Batteries & FT8 Report

[Howard Hoyt]

Peter,

You can get significantly more key-down time or run more FT8 power if you 
install our Kx22 heatsink:
(https://proaudioeng.com/pae-kx22-heatsink-elecraft-kx2/).  With the heatsink 
installed the rig still fits all of the cases Elecraft sells for the KX2.  
Running 5 watts FT8 is usually productive, but this past weekend here in NC our 
propagation was terrible for FD, seemingly worse that that for the west coast...

Cheers & 73,
Howie / WA4PSC

Re: [Elecraft] K3S glitching on startup

[Frank O'Donnell]

Thanks for the advice. Thankfully, there was a very simple solution. 
Although I had disconnected the CW paddle, as well as a number of other 
cables, I couldn't crane my head around enough to notice that I'd left a 
1/4"-to-1/8" adapter in the paddle jack on the back panel, which 
apparently had become partially unseated. When that was fixed, the 
problem went away.

This sounds like the K3S is getting commands fed to it when perhaps it

1) Check the front panel to see if any keys are stuck.
2) Disconnect the serial port then power up the radio.
3) If the above don’t work, reset the parameters. This is described on page 72 
of the K3S Owner’s Manual, Rev A1.

And if all that fails, try giving tech support a call.

There are 3 places where audio level is controlled and each one

be correct.  First is the SPKR level out of the computer. This should
be about 30%  {-18 dB} or so.  Then output attenuation on the lower
right of FLDIGI which should be about -10 dB to -15 dB .  Then the

Re: [Elecraft] ALC for Digi, One Last Check Please

[Bob McGraw K4TAX]

The pulsating is the result of the refresh rate of the display and the 
1500 Hz tone.  Change the TUNE tone to a non- 500 Hz interval such as 
1250 Hz. or 1700 HZ as such.   Yes, in FLDIGI the TUNE tone is a single 
frequency you have selected on the waterfall scale or in the box at the 
bottom of the screen.


When you setup and adjust the audio levels, the radio mode must be DATA 
A for PSK-31.  The audio level for correct ALC indication should show 4 
bars solid with the 5th bar flashing.  The Elecraft radios DO NOT 
operate like other brands in regards to the ALC indications.   The 
actual ALC in the Elecraft starts at and after the 5th bar on the ALC 
scale.   Before that the "audio level" is indicated.    Then set the PWR 
knob on the radio for the power output you desire.   DO NOT adjust the 
audio level to change power.


There are 3 places where audio level is controlled and each one needs to 
be correct.  First is the SPKR level out of the computer.  This should 
be about 30%  {-18 dB} or so.  Then output attenuation on the lower 
right of FLDIGI which should be about -10 dB to -15 dB .  Then the Line 
Gain on the radio {adjusts by the MIC knob} to about 30.   These are 
"ball park" numbers and should get you up and running with a clean 
signal.   If any one or more is near minimum or near maximum, you need 
to investigate further.


If needed I can send screen captures.

The video below (no audio) shows the ALC meter responding first to a "TUNE"
command from fldigi. This sounds like a pure tone in the headphones but the
ALC meter responds oddly, almost like it is pulsating. I expected ALC to
pretty much be steady.

Next in the video is just clicking T/R in fldigi with no typing. It sounds
as expected in the headphones (a trilling sound). The ALC response looks
better but I can still see the pulsations in there. I expected to see 4
bars solid and the 5th flashing.

I'm using the K3s sound card. Level in Windows is -14.7 dB. Level in fldigi
is -12.7 dB. The level control on the K3s is set for 18.

Re: [Elecraft] QRP FD KX2 Batteries & FT8 Report

[Bob McGraw K4TAX]

One FT-8 cycle is 15 seconds transmit, 15 seconds receive.  I construe 
that to be one cycle.   FT-4 is 7.5 seconds transmit, and 7.5 seconds 
receive. Perhaps I shouldn't have used the word "cycle" terminology.


I found a good bit of FT-8 and FT-4 activity on 6M during FD.

[Elecraft] ALC for Digi, One Last Check Please

[Kevin, N4TT]

I've made a few PSK-31 contacts on the K3s and I've not gotten any bad
reports. However, I'm still a little concerned about what I see for ALC.


The video below (no audio) shows the ALC meter responding first to a "TUNE"
command from fldigi. This sounds like a pure tone in the headphones but the
ALC meter responds oddly, almost like it is pulsating. I expected ALC to
pretty much be steady.

Next in the video is just clicking T/R in fldigi with no typing. It sounds
as expected in the headphones (a trilling sound). The ALC response looks
better but I can still see the pulsations in there. I expected to see 4
bars solid and the 5th flashing.

https://photos.app.goo.gl/4AaLaVu1r8UDv5LT9

Am I reading too much into this? Is this how your K3s responds?

I'm using the K3s sound card. Level in Windows is -14.7 dB. Level in fldigi
is -12.7 dB. The level control on the K3s is set for 18.

Also you can find version 2.1.0-RC-7 at the same site.  It is / has the

are largely antenna and location dependent (oh to live on a saltwater marsh). 
Running FT8 with the KX-2 on FD was an education and I’ve got to do some 
thinking about how to improve my chances if I decide to try this again. All in 
all great fun with some learning but can’t wait for more future propagation. 
Maybe I should by the Elecraft amp LOL.

discouraged me from pursuing that option.  I’m kind of angry at myself at this 
point for not pursuing it more diligently!

Re: [Elecraft] QRP FD KX2 Batteries & FT8 Report

[Bill Frantz]

Interesting question. He reports:


When our club’s plans for FD fell through at the last minute I set up 1B with 
my trusty KX-2 with a Bioenno battery and two internal KX2 battery pacs on my 
back porch. Got a Par 40-20-10 end-fed up about 40’ in a north-south 
orientation only to find band conditions here were pretty bad here in the north 
with QRN, QSB and faint signals at best.


It sounds like he was not depending on any of the home station 
infrastructure e.g. antennas, so I think that he was in class 
1B, one or two person portable or even perhaps 1Bb if he was 
battery QRP. YMMV.


But see also: 6.9. Batteries may be charged while in use. Except 
for Class D stations, the batteries must be charged from a power 
source other than commercial power mains.  To claim the power 
multiplier of five, the batteries must be charged from something 
other than a motor driven generator or commercial mains.

Simple. Read the WSJT-X online manual! There's a setup option on the

Re: [Elecraft] QRP FD KX2 Batteries & FT8 Report

[Bob McGraw K4TAX]

The WSJT-X software does have a provision for the correct Field Day 
exchange found under the Advanced tab.   I worked several stations on 
FT-8 and also on FT-4 with the latest version.    Most activity was on 
FT-8 of which a lot was found on 6M.   There are a few issues with RC-7 
for FT-4.  These are noted on the release page.

Re: [Elecraft] QRP FD KX2 Batteries & FT8 Report

[Brian Waterworth]

Hi Carl,

One of our club stations (6m) wanted to operate FT8.  I asked him to
install wsjt-x before coming onsite.  I then configured wsjtx-x for him.
It took less than 30s to do that.  Wsjt-x has an ARRL field day mode with
an entry field to add in your exchange.  Click click click and you’re
done.  It is very simple and wsjtx handles the cadence and the FD exchange
like a boss.  Wsjtx seemed to handle most situations and made operating a
joy.  It also gave me an opportunity to teach other hams and visitors how
to operate FT8 using wsjt-x because of its ease.

I used also wsjtx for my digital station as paired with a KX3.  I used the
KX3 with solar power to gain a 100 point bonus.  The KX3 was a champ.
Handled the voltage variances from the panel by automatically reducing
power from 10w down to 5w when the voltage wasn't quite enough for 10w.

Regards
Brian

Re: [Elecraft] More than you ever wanted to know about solar cycles

[Drew AF2Z]

I think it's fascinating. Anyhow, it's nice to hear a solar activity 
analysis that is based upon science. I half suspect that some of the 
sunspot predictions we've heard are made by ex stock market quants and 
commodities chartists; it wouldn't surprise me if they started referring 
to inverse head and shoulders, cup and handle patterns, sunspot 
breakouts, etc.


On the bright side (pun), if there is a long spell of inactivity in the 
solar magnetic field it will allow more cosmic rays to hit the earth's 
ionosphere which will help light it up a bit. Not sure if that is much 
of a silver lining for HF radio but it is something.

[Elecraft] T1 stopped cooperating

[LL]

My wonderful new T1 has just developed the following condition: I can't
access the Info or Bypass; tapping PWR always and only results in a
blinking yellow. I also tried to do the L-network test; no response. I
can't think of anything that changed, since the last time I accessed these
functions.  It will measure power, and it tunes.

Ideas...?

When the financial crisis hit in 2008 I stopped opening my 401(k)

I think I might do the same with propagation forecasts.

Re: [Elecraft] QRP FD KX2 Batteries & FT8 Report

[Carl Jón Denbow]

Peter,

I am curious how you got FT8 to do the proper FD exchange?  I read a post where 
some hams were discussing this and it sounded very difficult and complex, so I 
decided against trying it.  One guy actually had two FT8 programs running 
simultaneously, with one connected to HRD, which somehow enabled him to do the 
proper exchange.  His description made absolutely no sense to me, so though I’m 
an experienced FT8 op, I decided to forgo FT8 for this FD.  I’m curious how you 
accomplished this feat! 

73,

Carl

[Elecraft] Dual Receiver Tricks

[Dick Dickinson]

A late model SDR Receiver (only) is said to have a soon to be released
software update.  I've seen a demonstration whereby using 2 antennas and a
computer device, the unit will be able (to some degree?) determine signal
direction.

 

Does Elecraft have plans to develop K4D software with such capabilities or
sanction 3rd party development of such?  Will there be other software /
firmware development to come with the K4D beyond that of a dual receiver
K3/s?

 

Lastly, beyond control and perhaps IF output, will the K4 receiver(s) be
able to interface with external 'computers?'  (No, I'm not sure what I mean
by that!)

 

 

Kindly,

Dick - KA5KKT

Re: [Elecraft] KX3 batteries

[Walter Underwood]

That may be, though the discharge curves on the data sheets seem very similar. 
Note that the two data sheets use different discharge rates, like 2000 mAh vs 
2500 mAh. They both have the same specs for "Internal Impedance (after 
discharge to E.V.=1.0V)”: Approx. 25mΩ(at 1KHz). I have to admit that I have no 
idea what that means.

Re: [Elecraft] Low Power Output on 160 and 6 meters

[Everett via Elecraft]

Hi Jim,
You brought up a good point that I had not thought of and that is the voltage 
drop at the K3S itself. So I set up the voltage reading a the VFO B window and 
noticed that the voltage had dropped down to 12.1V when I keyed down, but the 
power supply said 13.7V at key down. So I shortened the power cable, by 32" and 
now it is 24" long. Now I see 13.1V at VFO B window and 100 watt on 160 meters 
and 105 watts on 6 meters. I increased the power supply voltage to 14V and now 
I see 13.3V at VFO B window, on key down and now 105 watts out on 160 and 110 
out on 6 meters.
So to make a long story short, the K3S will put out over 100 watts on 160 and 6 
meters if your power supply voltage is at 13.8 volts and you keep the power 
cord short. The additional 32" of power cord dropped the voltage by 1 volt on 
key down.

Re: [Elecraft] K3S glitching on startup

[Jack Brindle via Elecraft]

This sounds like the K3S is getting commands fed to it when perhaps it 
shouldn’t be. With that in mind, try:

1) Check the front panel to see if any keys are stuck. 
2) Disconnect the serial port then power up the radio.
3) If the above don’t work, reset the parameters. This is described on page 72 
of the K3S Owner’s Manual, Rev A1.

And if all that fails, try giving tech support a call.

[Elecraft] QRP FD KX2 Batteries & FT8 Report

[Peter West]

When our club’s plans for FD fell through at the last minute I set up 1B with 
my trusty KX-2 with a Bioenno battery and two internal KX2 battery pacs on my 
back porch. Got a Par 40-20-10 end-fed up about 40’ in a north-south 
orientation only to find band conditions here were pretty bad here in the north 
with QRN, QSB and faint signals at best. So switched to FT-8. I was forced to 
run QRP (which isn’t an issue as I am primarily a QRP contester anyway) as 
anything over 5 watts caused the rig to overheat to the point of automatically 
reducing power to 5 watts. Had WSJT, JT Alerts and even N1MM all cooperating 
and auto logging so all I had to do was stop reading the newspaper and 
occasionally glance over to the computer to see if I had worked anybody since 
the last time I clicked on a callsign. Then I started to notice my setup wasn’t 
completing a lot of calls which I had initiated. I started to pay more 
attention to the screen and discovered that it appeared to me that my signal 
was getting swamped out by QRO (100 watts or more on FD) signals which I 
couldn’t readily detect. At a suggestion from the FT8 FB group switched on the 
hold-my-transmit-frequency button. On CW my rates aren’t much different from 
QRP to 100 watts as I’m only 2 S-units down and aggressive operating skills can 
compensate for a lot of differences in power and I can deal with QRM I can hear 
and see. Not so on FT-8. I am rebuilding my contest station and only have the 
end-fed and an HF-2 vertical up right now and know that better results on QRP 
are largely antenna and location dependent (oh to live on a saltwater marsh). 
Running FT8 with the KX-2 on FD was an education and I’ve got to do some 
thinking about how to improve my chances if I decide to try this again. All in 
all great fun with some learning but can’t wait for more future propagation. 
Maybe I should by the Elecraft amp LOL.

Re: [Elecraft] KX3 batteries

I think Eneloop Pro have a higher internal resistance than the regular
Eneloop. In my experience, using both of them sequentially, the KX3 went
more quickly to the enforced 5 watt maximum output with the Eneloop Pro
cells compared to the standard Eneloop, despite the higher ultimate
capacity of the Eneloop Pro. But, YMMV!

[Elecraft] Buddy Pole

[Edward R Cole]

I got to see the Buddy Pole antenna for first time at FD last 
weekend.  Very impressed in quality of materials and ease of 
installation.  It was set up for 40m and I helped them tune it by use 
of my MFJ-269B antenna tuner.  The loading coil arrangement was a 
little awkward, I thought.  By nicer to have a roller inductor for 
quicker adjustment. A single radial wire was used and 2:1 balun to 
get 1.2 SWR.  Stepped 1:1/2:1/4:1 balun was nice.  Buddy tripod and 
fabric carrying case had me thinking this would be handy for portable 
operation with my RV at CG's.


I do not operate HF mobile so that would save having an antenna on 
the truck (its outfitted with 2m/70cm whip, 6m whip, and 2m 
horizontal loop for SSB).

Re: [Elecraft] Low Power Output on 160 and 6 meters

[Edward R Cole]

Well I have a K3/10 and KXPA100 with fw vers 5.60 (yeah I need to update).

K3/10 gets 10w on 14-MHz and 8w on 50-MHz.  KXPA gives 100w on 14-MHz 
and 80w on 50-MHz using  a Bird43 meter with a Bird dummy load.
Into an antenna power is dependent on match (as one would 
expect).  The KXPA only needs about 5.6w drive for full output on 
14-MHz but requires full 8w drive on 50-MHz.  Overdriving causes the 
3-dB attenuator to switch on.
