Re: [Elecraft] When Transmitting on FT8 - KPA500 has issues - KD8ZYD

Does it happen at 200 W? Sometimes RF in the shack shows up only at higher 
power levels.

Re: [Elecraft] When Transmitting on FT8 - KPA500 has issues - KD8ZYD

[Mark Goldberg]

I'm going to take these two postings and suggest the possibility of RF
getting into the USB link to the PC causing it to drop samples.

Check the grounds and make sure there is a good ground connection between
the PC, Signalink and the radio equipment. Try ferrite beads (Mix 31) on
the USB line or a different USB cable.

Re: [Elecraft] K3S subreceiver sound "problem"

[Vic Rosenthal]

If the a/b switch causes the problem to move, then it is something connected to 
bandwidth (etc.) settings and not a hardware issue with the subrx. The a/b 
switch doesn’t change which receiver goes to which ear (etc.)

Re: [Elecraft] When Transmitting on FT8 - KPA500 has issues - KD8ZYD

[Bob McGraw K4TAX]

A clue. at 500 watts with the KPA500 there is an issue.  At 50 watts 
using just the K3 there is no reported issue.  What's the difference?   
RF field strength.  Sounds like it might be and RFI issue.


Check all PL-259's and make sure they are VERY TIGHT.   Check jumper 
cables, between each piece of equipment and make sure they are in good 
condition and connectors are properly attached and installed.   If in 
doubt, replace them.

Re: [Elecraft] K3S subreceiver sound "problem"

[Robert G Strickland via Elecraft]

Thanks for the suggestions.
The subreceiver is on MAIN.
I set the selectivity for about 2kx in both receivers so that they are 
both using the basic SSB filters, ie no 400cps filter in the sub-. I 
re-checked all signal processing switches [ie, NR, NB, ATN, etc] to make 
sure they were the same. I set both receivers to the same frequency, 
both band noise and signals. I checked the rcv equalization; I don't 
think that the two receivers can be set up with different profiles, at 
least I couldn't do it. I turned off my hearing aids [the audio 
parameters of my hearing in both ears are pretty closely matched]. So, 
slightly better suggesting that some of the dullness was mismatched 
setup. However, the sub- is still duller than the main. It's like the 
there's a high freq cut on the sub-. In some respects it sounds like 
there's some audio distortion through the sub- that's not there in the 
main. That's it for the moment.

Good to send the video

It sounds like the Sound card is dropping audio frames then and can he test
with WSJTx in their TUNE mode.  Does the same thing happen.

If it was me, I would review the sound card settings for the sound card
device.  Make sure it IS the one you think it is.

Could the computer be suffering from high DPCs.. aka, is it busy doing
something else like a virus scan or indexing?

This is one of those times that it would be good to know more about the

Re: [Elecraft] Elecraft KX4

The ALT-512 looks interesting in that regard:
https://www.aerial-51.com/alt-512/

73, Todd KH2TJ



From:  John Harper 

But, what all this proves, is what's possible in the form factor in terms
of with.without PC and ease of connectivity from keeping audio in a digital
format for PC exchange.

If Elecraft made a similarly featured KX4 it would sell like hotcakes and
would be hitting the sweet spot of how so many people operate today:
portable, FT8, CW/phone, with and w/o a PC. What an attractive set of
features for new younger hams and those without the ability to have a
"proper" antenna.

Don, just a point of clarification.  The titles that Bill mentioned are

Re: [Elecraft] When Transmitting on FT8 - KPA500 has issues - KD8ZYD

[Jack Brindle via Elecraft]

Fred sent me the video, which is actually very revealing. First the change rate 
is very rapid, higher than I initially expected. The asterisk is on constantly, 
and the power off time is not long enough for power to drop to zero. But what I 
found very interesting is that the output power indication on the K3 is 
fluctuating at the same rate as the KPA500 is indicating. That leads me to 
believe that the K3 output is rapidly changing on and off. The next question is 
what might be causing this - it might be the K3, but it also could be upstream, 
in Fred’s Signalink or perhaps the computer / program that is feeding audio to 
the radio system.

With that in mind, and knowing the calibre of folks on the list who are very 
adept at digital setups, let's see if we can troubleshoot the system and get 
Fred going again the way things should be.

Sounds like the power from the K3 is too high.   Should be about 25 or

Re: [Elecraft] When Transmitting on FT8 - KPA500 has issues - KD8ZYD

[Mark Goldberg]

Can you watch the SWR when this happens? If the antenna is hard to tune,
the tuner may find a match, but it may actually be fairly lossy, with power
being dissipated in the tuner. As the tuner inductors heat up, they change
value, and the SWR goes up, triggering a retune. You should be able to see
the same thing with just a carrier at high power. If that is the case, you
should do something to your antenna to make it easier to tune up. This
happens to me on 160. My antenna is too short and presents a low impedance.
The tuner can tune it, but not for very long before it heats up.On SSB or
CW, the lower duty cycle doesn't heat things up as much.

Re: [Elecraft] When Transmitting on FT8 - KPA500 has issues - KD8ZYD

[Don Wilhelm]

Fred,

Is the KAT500 trying to do a TUNE?  It sounds like it may be.
If left in AUTO mode, the KAT500 can occasionally detect a false SWR 
result.  When that happens, the KAT500 will break the keying line to the 
KPA500 while it tunes.


With the KAT500 in AUTO - train the tuner for all band segments and 
antennas you use, then set the KAT500 to MAN for operation.


Do that and see if the problem stops.

If that is not the problem, connect the KPA500 (not the KAT500) to a 500 
watt or greater dummy load and see if you can duplicate the problem.


If it fails on the dummy load, contact supp...@elecraft.com.

How are you setting power out?  The K3 power out should be set to about 
25W to get full power.  What SWR do the KPA500 indicate and KAT500 
indicate?

Fred,

Does this condition also happen on SSB, RTTY, CW or only while running
digital mode?

Is it possible the PTT/key line is being dropped?  When the power drops is
there an asterisk (*) on the left side of the KPA500 display?  An asterisk
will appear on the left side of the LCD display if there is a valid PA KEY/
PTT signal is being received from the transceiver. If there is no asterisk
the amp isn't receiving a valid PA KEY/PTT signal from the transceiver.  If
there is an underscore instead of an asterisk it means that the amplifier
keying is being inhibited by a low signal on pin 11 of the AUX connector.

Re: [Elecraft] K3S subreceiver sound "problem"

Is the "dull and muffled" only with the 400 Hz filter?  Does the Subrx

If it is just the 400 Hz filter with the problem, it may be that the

Re: [Elecraft] How to view your Elecraft P3 remotely

[Jim N7US]

Win4K3Suite macros will work with the K3, P3, and KPA500/1500, even in the same 
macro, I think.

Jim N7US

-Original Message-

Do you also have access to the P3 controls remotely via the RS-232 port?  My P3 
loses its span end-point settings if I change the band via CAT commands and I 
would have no way to reset them remotely.

A secondary problem we encountered at W7RN with web cams is that they have a 
tendency to gobble up BW.  Even those that operate deferentially [sending only 
the changes or sending a screen only when something changes] were a problem, it 
seemed that something was always changing in the image, even if only by one bit 
in one pixel.

Having access to the remote panadapter would be really cool.

Mobile is a reach from KX4 as the topic - but - here's my drift:

I outfitted my new (in 2016) truck to be equipped for 
HF/6m/2m/70cm.  Mostly when parked in eve. with our 5th wheel trailer 
(even provided for two coax lines to the trailer for operating the 
KX3 on the dining table).  I can run the 6m-70cm while underway 
(mobile) but most of the time the radios are off when driving. 80m 
and 20m hamsticks did not tune well mounted in the bed so going to 
not bother running HF-mobile.  Buddipole looks like a convenient HF 
portable antenna.


Towing a 30-foot trailer is a full-time job and needs no distraction 
(total rig length is 47 foot).  I will eventually get APRS tracking 
beacon working.(which runs automatic).

[Elecraft] OT: Open Source Code

[Bill Frantz]

I must strongly disagree with Bob. Before I retired, most of my 
career was spent writing code. This code became the property of 
my employer, and when they went bankrupt, I could not access it, 
support it, or use it. I never want to be in that situation again.


I will write open source code, but prefer to write public domain 
code. My reward comes when people use my code for their own purposes.


I will also point out that much of the code that supports the 
Internet is open source. For example: the Firefox browser, the 
clang and gcc compilers, the apache web server, the openssl 
encrypted transport layer suite, and the code that does basic 
Internet routing. The Linux OS is open source. In amateur radio, 
wsjt-x, cocoaModem, and N1MM are open source.


WE all benefit from open source software, and it exhibits the 
amateur radio spirt of sharing.

Re: [Elecraft] K1 4-band board wanted

[LL]

INCREDIBLE RESULT!!!

I called Elecraft, and a few hours later, they called back: they found ONE
two-band board, and they're kitting it up with 20 and 80 for me. I'll have
to swap the boards to change, but I'll have a four-band K1.

EXTREMELY satisfied customer, still.

Re: [Elecraft] Fusing power cable on K3

Thank you everyone who responded.  My “new” K3 is now sitting in the place of 
honor next to my old favorite K2.  Now to read all the volumes of K3 manuals 
(for all the included upgrades) by Elecraft and the late Fred Cady to find out 
what all the knobs and buttons do.

Yes, Hi Bill.  Was great to see you again after all these years.

[Elecraft] How to view your Elecraft P3 remotely

[paule408--- via Elecraft]

I have long been using my K3 remotely and I have wished for a simple way to 
view my P3 via remote. 
I just found a solution that is working nicely. 
I bought a $20 Wyze Cam 2 which is a 2.4 Ghz webcam with an app for my phone. 
The Wyze cam will focus closely on the P3 giving me a full screen display via 
my Iphone (using the Wzse App)
The Wyze cam will live stream video directly to my phone with minimal latency. 
This solution is working nicely and at $20 for the camera, you can't beat the 
price!
You can find out more about the Wyze camera at Wyze | Making Great Technology 
Accessible | Smart Home Devices

Re: [Elecraft] Fusing power cable on K3

[K8TE]

Bob has it right, when used mobile which I do a lot for QSO parties.  Here is
the rationale:

The pictorial at right is from this author's May 2015, QST, starting on page
35, entitled The Modern Mobile. It clearly represents the correct wiring
scenario, whereas the negative lead goes to the same chassis grounding point
as the battery's chassis ground point. And as shown, the negative lead fuse
should not be removed. The reason is, if the grounding point should lose its
integrity, excessive current could flow through the transceiver's negative
lead. It also prevents a minor ground loop between the leads.

You can find more details at:  http://www.k0bg.com/wiring.html.

And hello Dave!  I saw some of our Cherryland ARC friends at HamVention
again this year.

Re: [Elecraft] K2: "Pop" when switching certain bands

[Jim KO5V]

Don,

I tap menu, then select t-r, then hold menu to move the cursors underneath the 
0.00. I then tap Display and see 8r nor, then tap again to select 8r hold. 
Within a second or so, the display atomatically goes back to t-r with 0.00 
underlined. I then tap menu twice to exit.

Please see my last email about the "10M"-20M. I meant 30M. I was evidently 
thinking 10Mhz...sorry.

I'll check the caps as you suggest.

Thanks again. 73,

Re: [Elecraft] Elecraft KX4

[Alan]

Not publishing the source code is no guarantee that someone won't rip 
off the software.  Remember "NET/ROM"?


https://www.tapr.org/pr_intro.html#NR

It was a pre-programmed memory chip that you plug into a packet TNC to 
give it super-digipeater capability.  The software was copyrighted, but 
that didn't prevent some hams (in Germany as I recall) from running a 
reverse compiler on the code, making a few minor changes, and 
re-compiling it so they could make pirate chips.


It's not like the copyright owner was making a killing on the product.  
I don't remember the price, but as I recall it was reasonable.  But too 
expensive for some people who can't resist a "bargain".

Re: [Elecraft] K2: "Pop" when switching certain bands

[Don Wilhelm]

Jim,

On the setting of 8R HOLD, are you exiting the menu after making the 
change?  (tap MENU twice).


You may want to look at the RF board schematic sheet 3.  All the 
capacitors around U1 (The IO Controller) can be checked for proper 
values (most are .001uF marked 102). Also check that they are all in the 
proper holes (and not through an adjacent via hole).


How are you switching directly from 10m to 20m?  With the BAND+/BAND- 
buttons, you must cycle though 15 meters going between 20m and 10m, so I 
am a bit confused by your statement.   If you are using a software 
application to switch, remove it and test from the K2 buttons.

Maybe it's just one of those "it just does that" situations, but it seems a bit

The firmware is open source, thus all the clones. Chris recently complained

A group in Germany is now providing the lion's share of updates.

But, what all this proves, is what's possible in the form factor in terms
of with.without PC and ease of connectivity from keeping audio in a digital
format for PC exchange.

If Elecraft made a similarly featured KX4 it would sell like hotcakes and
would be hitting the sweet spot of how so many people operate today:
portable, FT8, CW/phone, with and w/o a PC. What an attractive set of
features for new younger hams and those without the ability to have a
"proper" antenna.

I am hesitant to experiment too much with my mcHF because support and
documentation is so lacking. I can't easily recover from an error by
reading - I'd have to ask in a forum and hope someone both knows the answer
and isn't too burnt out by being asked other questions, that he'll answer
me.

If a company with Elecraft's reputation produced such a rig I'd probably be
moved to write a tributary haiku, or maybe even a limerick.

I’m with you 100%, John! Hope Elecraft is listening!

Love the mcHF, but there is really NO customer support. If the current
group of developers aren’t interested in fixing a bug or adding
something new, you’re told to do it yourself. Not something I’m
interested in doing, or really able to do. But as is, its still a fun
and innovative transceiver!

Elecraft could do it right!

Re: [Elecraft] K3 data mode fail

[Don Wilhelm]

Skip,

Make certain the K3 is getting audio into the Line In jack.
Pull the speaker or Line Out cable from your soundcard and plug 
headphones or amplified computer speakers into that soundcard jack.
Then do a TX from your software application.  Do you hear any audio 
tones?  If not, check the computer/soundcard.


If audio there, plug in the cable to the K3 Line In making sure the 
plugs are fully seated on each end.  You could have a bad cable.
Since you have good audio to the computer on RX, swap the two audio 
cables between the soundcard and the K3.  If you have an OK waterfall 
display, the cable between K3 Line Out and soundcard line in (mic) is 
working.


If you still have problems, contact supp...@elecraft.com for further 
analysis.

Re: [Elecraft] Elecraft KX4

[Rick WA6NHC]

While I agree that a panadapter is unneeded, unwise and distracting when 
operating mobile, one should plan for safety by minimal interaction with 
any device added to a vehicle.  This would include any touch screen 
display, since we won't avoid them.  For example;


The control heads of my V/U/HF radios are on the dash (I built a vehicle 
non-destructive frame for mounting) along with the (voice controlled) 
GPS so they are not distracting, easily reached for the few times 
adjustments are required and most importantly, WITHIN the normal visual 
scanning range of the driver (left mirror, windshield, gauges, 
windshield, right mirror; reverse and repeat).  They are high enough to 
be seen without looking down (use peripheral vision for the road), yet 
low enough to not block vision of the road (drivers with a height issue 
too).


The HF station uses a Turbo Tuner and Tarheel, one button to tune it is 
the only driver interaction.


The meters, don't matter (and can't be seen without reading glasses 
anyway), only the frequencies are truly needed as visible to the 
driver.  The use of preset memory slots makes it much safer.


Each radio has function buttons on the mic as well, so direct 
interaction is very low.  The radio scanner (in the console, next to the 
phone, for traffic problem awareness during travel for potential 
re-routing) is not among this collection on the dash since the mode of 
speech tells you who is talking (cops don't sound like fire and medical 
is different altogether).


Placement also allows the passenger to be the operator; and they also 
manage the sound system when the HF is turned off.


However, while it was once common for me to multitask while driving a 
large fire truck; it's a good idea to note that aging of the driver 
lowers the ability to do this well.  If you don't pay attention to that, 
it's possible to learn that reduction of ability in a negative manner.  
Take note; that reduction creeps up over time.


Setting up a mobile station requires significant planning and thought 
along with the understanding that sometimes, the OFF button is the best 
choice; yes even a simple dual band V/UHF (mostly used for APRS to 
reduce the 'where are you?' calls and to allow the coffee to be fresh 
upon arrival).


(I typically only use mobile HF when parked or while hauling the fifth 
wheel on an interstate but never in a city or other traffic dense 
situation.  After decades of my career, listening to multiple audio 
sources at the same time is second nature to me; extract what is 
relevant, ignore the rest. The fifth wheel has it's own station.)

[Elecraft] Elecraft KX4

[John Harper]

I sometimes doubt that Chris M0NKA ever meant for it to be a commercially
viable rig but, despite what you correctly mentioned, it has become one. I
think his original intent was to provide a project to experiment with
coding etc - the platform for that experiment just happened to be a radio.

The firmware is open source, thus all the clones. Chris recently complained
that he is now expected and often asked to provide support for the Chinese
clones! That's gotta burn...

A group in Germany is now providing the lion's share of updates.

But, what all this proves, is what's possible in the form factor in terms
of with.without PC and ease of connectivity from keeping audio in a digital
format for PC exchange.

If Elecraft made a similarly featured KX4 it would sell like hotcakes and
would be hitting the sweet spot of how so many people operate today:
portable, FT8, CW/phone, with and w/o a PC. What an attractive set of
features for new younger hams and those without the ability to have a
"proper" antenna.

I am hesitant to experiment too much with my mcHF because support and
documentation is so lacking. I can't easily recover from an error by
reading - I'd have to ask in a forum and hope someone both knows the answer
and isn't too burnt out by being asked other questions, that he'll answer
me.

If a company with Elecraft's reputation produced such a rig I'd probably be
moved to write a tributary haiku, or maybe even a limerick.

I’m with you 100%, John! Hope Elecraft is listening!

Love the mcHF, but there is really NO customer support. If the current
group of developers aren’t interested in fixing a bug or adding
something new, you’re told to do it yourself. Not something I’m
interested in doing, or really able to do. But as is, its still a fun
and innovative transceiver!

Elecraft could do it right!

Re: [Elecraft] OT: Distracted driving

[Rick Robinson]

As a rover several years ago I operated mobile between grids. I had a F150
regular cab in which I used a Icom 706mk2g. The body of the radio was
mounted behind the seat with the head unit mounted on the dash. I used a
one earpiece headset mic plugged into the radio body and I used a
footswitch mounted on the floor where the dimmer switch used to be.Remember
those ? This was a two wire connection to the head unit for Ptt only. Other
than looking at the display which was in line with the instrument panel, I
had both hands on the wheel and minimal visual distraction. This setup
could be adapted to most any radio for a very safe way to mobile. Forget
cw. One hand would be operating the key, thus limiting your control in a
fast response situation . But it boils down to thisdrive first, radio
second.

Do NOT "Nanny State" the design of the radio  As a compromise, put 
in a firmware option that turns the panadapter OFF while the vehicle is 
in motion or something like that.  But even THEN, make it where the 
OWNER of the radio may affirmatively take action to disable this 
nanny-state-like "feature".  SOME folks are trained for and perfectly

Re: [Elecraft] K2: "Pop" when switching certain bands

[Don Wilhelm]

Jim,

Do you have 8R Hold turned on?  If not, set it on.

Remove that external DSP speaker and see if you still have objectional pops.

Do you have the KDSP2 installed?  On older K2s with the older KPA100 
installed, you can experience some harmless "pops", especially if you 
have the DSP NR turned on.


The number of relays which are switched during a band change varies 
depending on which bands you are coming from and going to - so relay 
clicking is normal.


You might want to check RF Board Q23 to be sure it is working.  The 
voltages during receive and transmit should be as shown in the DC 
voltage tables.

Good Afternoon,

Today I noticed a "pop" on the audio of my K2 when I changed in and out 15M, so 
I checked the switching on all bands:

When changing from 15M to 12M or 17M it is fairly loud. Changing from 12M or 17M to 15M causes a 
fainter "pop". A much more attenuated "pop" happens when changing from 14M to 
10M, and also from 10M back to 14m.

Also, on 15M, when changing from VFO B to VFO A I hear a loud "pop", but it 
does not happen going from A to B.

The fainter "pops" might have always been there, but the ones on 15M are loud 
enough to cause the clip light on my DSP to turn red.

I wonder if it has something to do with diodes across relays, or the relays 
themselves.

Any more ideas?  Thanks in advance.

Re: [Elecraft] K1 4-band board wanted

[Don Wilhelm]

Lloyd,

Elecraft does still have some band kits for the 2 band board.  Order the 
kit for the band you wish to switch to.

There are no new 2 band boards available from Elecraft.

Yes, if you can find another 2 band board, you can change the band 
boards easily.  The K1 will remember the OPF offsets for up to 6 bands. 
You only need to change the board and set the "b1" and "b2" menu 
parameters to match the bands of the boards in use.

[Elecraft] Elecraft KX4

[John Harper]

I recently bought a mcHF (a real one, not a clone) and, as much as I like
it, I wish Elecraft would make a similar radio.

The main advantages of a mcHF over anything else out there are its built-in
panadapter and its one-cable connection to a PC for digital modes. No PC
required for SSB, CW or PSK31.

The KX2 and mcHF are of a similar size and are shown together here for
comparison:
http://ae5x.blogspot.com/2019/05/comparing-mchf-and-kx2.html

Disadvantages of the mcHF - and where an Elecraft (KX4) would shine - are
in support and documentation. I hope we'll see a KX4 soon, with all the
Elecraft advantages and none of the mcHF's shortcomings.

Re: [Elecraft] Fusing power cable on K3

[Bob McGraw K4TAX]

Since it is only to be used not mobile, I would not add a fuse to the 
power cord.   It only adds a few tenths ohms but it still is added R 
that isn't needed.


As to ICOM, any radio that is used mobile should be fused in the DC Pos 
and DC Neg leads.

 It will be only used in the shack, not mobile.

That gentleman is mistaken unless something happened while I was not
watching, the KX3 does up to 15 watts.

If I use a large power supply and turn the KX3 on its side and shake it - I
still only get 15 watts according to my Tird meter (Trusty ole Bird).

Re: [Elecraft] Help me! Kpa100 broked during lightning

[Don Wilhelm]

Juha,

Whenever I had a lightning hit KPA100 to repair, I always replaced all 
the active devices (including all diodes) in the KPA100.
Even if the devices are not currently failing, there is a good chance 
that they have been stressed and will fail later.


If you are using a USB to serial adapter, that was likely damaged too.

Don W3FPR

Hello,

Yes, all cables was connected during the first lightning bolt nearby.

Now K2/10W is ok! All work fine, luckily.

But with KPA100:

1) Metering (K2 LED paragraph) do not show anything.
2) I get 10W and 100W output, but can't adjustable power.
3) KPA100 don't talk with computer, yes computers COM port is broken too.
But I tested with another working COM and the same situation; don't work.
4) Pressing TUNE K2 show "0.1  9.9-1" (10W) and 1  1.0-1 (100W).

I replaced D16 and D17 on KPA100. Nothing changed.

Re: [Elecraft] K3 data mode fail

[k2te]

Skip,

Check your soundcard cable to your Line-in jack.  I had the same problem
occur several times before I discovered the problem was the cable.  I
pressed on it at the line in jack while testing and the power out came
back up.  Same symptoms: no output, RX signals OK, CW and SSB OK. 
Replaced the cable and everything FB now.

Re: [Elecraft] Help me! Kpa100 broked during lightning

[Dave]

Sounds like the RS-232 chip in the amp may be fried, especially if the PC com 
port it was connected to fried. 

I’ve seen this in the public safety world. Lightning hit our phone lines coming 
into a PC at the site and took out every com port (multi port). Also com port 
on all equipment attached got zapped. 

Not sure what else. I do not own the KPA100 so cannot add anything else.

Re: [Elecraft] Fusing power cable on K3

[Roy Koeppe]

No, fuses have voltage drop both in their elements and contacts. Just what 
you're trying to defeat and avoid.


73,   RoyK6XK


I recently purchased a used K3 and am building a short power cord (after the 
discussion of voltage drop from longer cables).  I noticed that the power 
cable that came with my IC7000 has fuses in both leads.  Since the K3 has a 
built in fuse it is still a good idea to put fuses in both sides of the new 
power cable?  It will be only used in the shack, not mobile.
