[Elecraft] DIGTAL INTERFACE EA3BLQ

[Behiels Jean-Pierre]

 

Hi K2 users;

 

We all now that the digital interface realised especially for the K2 by
EA3BLQ in past,is SK despite !

A lot of time is gone,but are there some alternated suggestions,about the
building concept of EA3BLQ.

I can imagine that someone has continues his PCB art work for further K2
digital interface users .
I personally not need for my own purpose.

I do have build a ON4AEF external digital interface for my own into a second
K2 box (Don W3PFR now about my concept hi) .  

But a friend of mine who also have a K2 and he like to build a digital
interface circuit for his K2 like EA3BLQ has build.

He prefer the design of EA3BLQ but he needs some PCB's of Pedro.

>From there my request if someone has some dupes EA3BLQ boards or are there
some copies released around his project hi ..



Kindly regards es thanks anyway

 

73's Jean ON4AEF.

Re: [Elecraft] Feature Request: improved internal keyer and CW PTT behavior

[donovanf]

Hi Vic, 


Yes, if you place your K3 in CW mode with VOX off and QSK off, 
the amplifier key output turns on and off during every Morse element.

Re: [Elecraft] Feature Request: improved internal keyer and CW PTT behavior

[donovanf]

Hi Fred, 


CW PTT is the K3 CW operating mode when VOX is off and 
QSK is disabled. 



Two distinct categories of messages are sent during CW contests: 


-- prerecorded messages (CQ, exchange and end of QSO messages) 
They're usually stored in an external computer so that they can 
be instantly started and prematurely stopped by the contest 
logging program if necessary. 


-- real time operator originated messages, keyboard or paddle sent 


For pre-recorded messages its important that the transceiver 
switch from transmit to receive in less than the timing for 
one Morse inter-character space (three Morse elements). At 
35 WPM an inter-character space is approximately 100 milliseconds. 


Transmit-to-receive switchover longer than 100 milliseconds will 
frequently result in the receiver not being active when the other 
station is sending the first Morse element of his callsign, 
resulting in a mis-copied callsign or a request for a repeat. 


In order for a K3 to meet the 100 millisecond transmit-receive 
switchover requirement for pre-recorded messages, the K3 can be 
operated in QSK mode, CW PTT mode, or CW VOX mode with 
front panel VOX delay set to near zero. 


For real time operator sent messages (e.g., requests for repeats 
or brief text messages) the transmit-to-receive changeover timing 
isn't as critical and a 200 millisecond VOX delay is usually acceptable. 


Many contest operators prefer to use a paddle to send real time 
messages, some use a computer keyboard. If the internal keyer 
in the K3 is used to send real time messages, only QSK can be 
used with the current K3 implementation of its internal keyer. 


If CW PTT is selected by the operator, unfortunately the K3 
actually sends the message in QSK mode. If the operator selects 
CW VOX mode, a very short VOX delay will result in VOX 
dropouts between every character and word. If the operator 
increases the VOX delay to at least 250 milliseconds to avoid 
inter-character and inter-word dropouts, the 100 millisecond 
transmit-receive switchover for real time messages cannot be 
achieved because unfortunately the K3 adds a VOX delay to 
the end of the computer generated PTT when the K3 is in VOX 
mode. 


One solution is to operate the K3 only in QSK mode, but many 
operators prefer not to use QSK. 


A very effective solution is to use an external K1EL Winkeyer 
and not use the internal K3 keyer because of its unacceptable 
behavior for contest operation. 


Perhaps the most desirable solution is to correct the shortcomings 
of the current K3 internal keyer and eliminate the unwanted 
VOX PTT delay so that K3 behavior is similar to the Winkeyer.

Hmmm ... explain what "CW PTT" mode means, that may be the cause of my 
lack of understanding. With VOX enabled, QSK off, and using the 
internal keyer, my K3 reverts to receive on the delay time I have set 
for CW. I tried it with a minimum delay [whatever 0.00 sets] and it 
drops immediately, between letters and sometimes even between code 
elements if I get a bit sloppy with the paddle. 

Obviously, I'm doing this different than you are.

Re: [Elecraft] P3 Product suggestion

[Tim Tucker]

I'd go for something like this.  The problem I have with the P3 is that
it's a great concept packaged in a pre-2010 UX and we're encroaching on the
year 2020.  .  One tweak to the suggestion:  It's shouldn't be VGA out -
that standard and associated video resolution is dead as dead can be. It
needs to be stepped up to a modern video monitor interface and resolutions

There's tremendous commonality between the P3 and PX3 code base.  The same
will be true for your P3x.  Mouse support is trivial.  I'd simply push for
mouse support in conjunction with the P3 / PX3.  You'll get it for "free"
with your P3x.

Support for a gaming mouse is more involved.  All of the keyboards supported
by the P3 / PX3 share a common HID report.  I'd expect the same to be true
for the supported mice.  A gaming mouse will have an  extended HID
descriptor and report.  I don't envision a gaming mouse being supported.

Re: [Elecraft] P3 Product suggestion

[David Orman]

This would be quite nice. Add better than SVGA resolution and now we're
cooking with gas. Touchscreen monitor support would be the bee's knee's.

As for the integrated version, maybe we will see that in a K4 or whatever
the next radio iteration is called? I would definitely be interested!

[Elecraft] OT: Hookup Wire

[Phil Hystad]

Slightly off topic but definitely ham radio oriented and my only ham radios are 
all Elecraft gear.

I am looking for stranded copper hookup wire, say #20 to #24 with very flexible 
insulation.  I have some of this now, like about 7 inches, but I need more.  I 
do not know any brand names or even what this is called.  A friend of mine 
thought it might be the Teflon insulated wire.

Can anyone suggest some brand names or products that I can search on-line?  
Out-of-band responses please to keep this OT topic from crowding up the forum.

Thanks,

[Elecraft] P3 Product suggestion

[Dave Fugleberg]

The recent thread titled "P3 Point and Click" got me thinking...
I have a base model P3 (no VGA board or TX monitor). I really like how
smoothly it integrates with the K3. It has replaced the Softrock and
software panadapter that I had been using, with much less complexity- it
just works.

However, I do sometimes get frustrated with the 'twist and tap to QSY' user
interface. It is far too easy to accidentally rotate the knob in the
process of tapping it, and making a large excursion in frequency takes much
longer than a mouse point/click would.

My humble suggestion/wish would be for a whole new alternative product -
let's call it the P3x. The P3x would be a small box with IF in, VGA Out,
serial in/out, and a USB port for a mouse.  The user could supply their own
monitor in a size of their choice. It would basically be the same
electronics as the P3, but without the screen, controls, and big (mostly
empty) case.

All the normal P3 controls would be replaced by on-screen buttons with
dropdown menus where appropriate to set parameters like SPAN, etc. Perhaps
the mouse wheel could be incorporated in place of the knob for adjustments
like REF LVL. Of course, "Point and Click QSY" would be supported.

For extra credit, support for a 'gaming mouse' could be included (one of
those mice that has several additional configurable buttons) to support the
standard P3 buttons for those who prefer tactile buttons over clicking
on-screen controls.

To me, this would be a great alternative to the current P3, as it provides
the same excellent integration with the K-line, plus the choice of display
size AND mouse support.  I suspect that many ops who add the SVGA option to
their P3 do so simply for the larger screen, which makes the P3's own
screen redundant anyhow. It also seems odd to me to reach for the P3
controls while looking at the external monitor, so having the controls
integrated on screen with mouse control would be more natural.

While I'm dreaming, I'd also like it available as a P3i - same as the P3x,
but built as an internal option for the K3/K3s. OK, I have no idea where
that could fit in a fully loaded K3/K3s, but this is only a dream, after
all...

So, maybe I'm the only one who thinks this would be a great addition to the
product lineup...but there's my idea. No need to pay me royalties, but I'd
like SN 001 please :)

Hi Fred,

I never operate QSK,  my amp relays aren't fast enough and they

CW VOX or CW PTT.

The K3 works fine in CW VOX mode, except for the odd behavior
that after PTT is released the VOX delay continues to keep the
transmitter active until the delay set by the Delay pot times out.

Its a different story in CW PTT mode (not QSK).   PTT is very
responsive (the transmitter always releases immediately after PTT
is released regardless of delay pot setting).   The problem is that if
you use the internal K3 keyer in CW PTT mode, the radio actually
transmits in QSK mode risking damage to slow amplifier relays.

Like many K3 users, I solved the internal keyer problem by using a
K1EL Winkeyer connected to the K3  Key and PTT inputs.  That
solution works exactly the way the K3 should work if the logic for
the K3 internal keyer worked as it should.

I'm really confused now [a not uncommon state for me].  I have "mature"
K3 S/N 642.  The VOX delay is adjustable by holding the SPEED/MIC knob.
There is a separate delay for CW and SSB.  I normally run QSK, but I
just tried semi-breakin now and the two modes have two different
adjustable delays.  I use a Winkey-3.  I used to use the internal K3
keyer, and I don't remember any problems then either.  Before I got the
KPA500, my amp wouldn't do full QSK so I ran semi-breakin all the time.

The subject of the original email doesn't note the Elecraft product, if
it's not a K3 [or K3S I guess] disregard this.

Re: [Elecraft] Feature Request: improved internal keyer and CW PTT behavior

[donovanf]

Hi Fred, 


I never operate QSK, my amp relays aren't fast enough and they 
make too much noise. Like many K3 users, I always use either 
CW VOX or CW PTT. 


The K3 works fine in CW VOX mode, except for the odd behavior 
that after PTT is released the VOX delay continues to keep the 
transmitter active until the delay set by the Delay pot times out. 


Its a different story in CW PTT mode (not QSK). PTT is very 
responsive (the transmitter always releases immediately after PTT 
is released regardless of delay pot setting). The problem is that if 
you use the internal K3 keyer in CW PTT mode, the radio actually 
transmits in QSK mode risking damage to slow amplifier relays. 


Like many K3 users, I solved the internal keyer problem by using a 
K1EL Winkeyer connected to the K3 Key and PTT inputs. That 
solution works exactly the way the K3 should work if the logic for 
the K3 internal keyer worked as it should.

Frank,
Pardon my ignorance on this issue if the below is off target.
The asynchronous nature of an external ptt appears to be a problem.
Suppose the K3 is in the middle of a long 100 watt dash and the external ptt 
signal is dropped. It clearly takes some time for the RF tail to drop to zero. 
One would seem to need to add some delay time for this to happen. To avoid 
clicks one wants a shaped tail. I dont see how the K3 can immediately go to RX.
How fast a turn off and go to RX action do you want? Is the normal 5 ms tail 
fast enough?

Of course if Winkey logic is programmed within the K3 the asynchronous problem 
goes away.

The adjustable TXDELAY issue where the CW gets QSD with a setting more than 8 
ms is an issue that has existed from day one. People started complaining about 
it on day 2. Elecraft has know about it for a long, long time. From what I am 
able to glean about the problem is that it may be really difficult to fix. 
Apparently the timing has to be fixed in many places in the code to produce 
good CW at all values of TXDELAY. If the fix were a simple one, it would have 
been fixed years ago.

Okay, lets take Eric's lead and open an interesting thread directly
related to an excellent Elecraft product.



For years many of us have suffered with the odd behavior of the K3
in CW PTT mode. There are at least two inexplicble aspects of K3
CW PTT behavior that have forced many of us to use external
Winkeyers rather than the poorly designed internal K3 keyer logic
when the K3 is in CW PTT mode.


For CW contesters, its necessary to operate the K3 in PTT mode
to avoid unwanted VOX delay. But for some strange reason the
K3 always applies VOX delay after external PTT is unasserted.
I can think of no logical reason why VOX delay should be applied
at the end of the external PTT input when the K3 is PTT mode or
any other mode. When PTT is unasserted, the K3 should always
immediately return to receive mode, no exceptions.


When using the internal K3 keyer when in PTT mode, for some
inexplicable reason the K3 behaves like its in QSK mode. The
only way to avoid this is to use VOX rather than PTT mode or
to use a foot switch when in PTT mode. Both alternatives
are unacceptable.


The band aid solution many contesters use with excellent results
is to avoid using the internal K3 keyer and to use an external
K1EL Winkeyer that generates both a key output and a PTT
signal generated according to well designed Winkeyer CW PTT
logic.


Why can't the K3 implement logic similar to the Winkeyer to
generate the equivalent of "Winkeyer PTT" when using the K3
internal keyer when the K3 is in PTT mode?

[Elecraft] KXV3A/B

[Alan. G4GNX]

Can someone tell me what the difference is between the KX3VA and the KX3VB 
modules.

Has an upgrade kit been made available to convert the ‘A’ to the ‘B’ and do I 
need it for my K3?

73,

Alan. G4GNX

[Elecraft] KX3/KXPA and Ameritron ALS-1306

[David Gow]

Ameritron does not make a band switching cable for this combination.  Does
anyone have information for me to make or modify a cable?  The combination
works great but I sure miss the automatic amplifier band switching.  I have
the KX3 and the KXPA100 (using the KXPA100 utility command tester) both set
at 9600 baud because the ALS-1306 only accepts 9600 baud but I don’t
understand serial cables very well and the ALS-1306 does not use a standard
straight through cable or a null modem cable either.  It uses custom
proprietary cables for different radios.

[Elecraft] K3S Receive Settings on WSJT-X

[stengrevics]

I am operating MSK144 on 6 meters.  I have a fairly high noise level which
requires use of AGC, NR and NB to get the noise level down on other modes. 
But, if I understand correctly, I shouldn't use those features on WSJT-X. 
That leaves me with that noise level.  

I would be glad to know what settings other K3S users employ on WSJT-X.

Thanks,

John

[Elecraft] XG3 Firmware revision 1.19 Available for download

[n6hz]

XG3 Firmware revision 1.19 has been released.  Use the XG3 Utility to copy
the files from the Elecraft FTP server and perform the download to your XG3.  
You can get the latest version of the XG3 Utility from our website:
http://www.elecraft.com/XG3/xg3.htm#xg3util

This revision has the ability to use 'meta-characters' in the 'W' command. 
Previous versions only allowed meta-characters  to be used in the Morse
Memory feature.   This new feature allows a user to connect their XG3 to a
PC via the XG3 Utility and create multiple command sequences using the
'Command Tester' Utility page.   Please refer to the XG3 Product Manual for
more information regarding Morse meta-characters. 

Release notes: 

Revision 1.19 February 6, 2017

•   The serial command ‘W’ can now interpret the same meta-characters that 
the
Morse memory (WM) command utilizes.  This allows the XG3 Utility’s Command
Tester to invoke a variety of complex macros using the programmable buttons
in the Utility.  Macros executed via the ‘W’ command can contain up to 93
characters. 


Very 73, 

Paul N6HZ

Re: [Elecraft] (OT) Follow-up on CW Resonant Speaker

[Walter Underwood]

This was discussed in the original string. The KX2 and KX3 have 100 mW per 
channel of audio out the phones jack. The K3S is 2.5 W/channel.

I use this 15 W per channel stereo audio amp with my KX3. The cost fluctuates 
between $8 and $13 for no obvious reason. It is a deal at either end of the 
price range.

Re: [Elecraft] (OT) Follow-up on CW Resonant Speaker

[efortner]

Stan,

I have built three of the resonant speakers per the QST article. I am using a 
K3s and have plenty of audio without an amplifier. The three speakers were all 
in the ballpark of 700 Hz. I took a 2 inch coupling and put on the street elbow 
and it resonates at about 500 hz. There might be slightly more audio coming out 
of the external speaker but when the resonant speaker is switched on the noise 
level drops enough to be noticeable so the project was worthwhile.

Re: [Elecraft] [OT] end-fed halfwave antennas

[Wes Stewart]

Since this was individually addressed to me as well at the reflector, I guess 
I'm expected to respond.


I will keep it brief.  I don't recall Devoldere saying anywhere in his book that 
end-fed half-waves didn't work.  Also, he wasn't advocating 0.35 lambda radials, 
he cited Brown having calculated that the current peaked 0.35 lambda from the 
base.  So you're making that up.  When contest scores become supporting 
evidence, I have nothing else to offer.



On 2/14/2017 9:48 AM, Guy Olinger K2AV wrote:

In spite of ON4UN's 4.3, I stand by my prior statements concerning the
excellence of end-fed half wave antennas (EFHW), and their non-existent
requirements for vast counterpoise. In that specific regard, ON4UN is
unfortunately off the mark. More on that below.

Those of you using the becoming popular (?) EFHW portable antennas with
your excellent Elecraft portable rigs, you do NOT need to worry about
putting down a dense 0.35 wavelength radial field for them to work very
nicely.

I've had 50 plus years experience with 80m EFHW antennas, particularly the
EFHW inverted L or EFHWL. I, and all those I have helped install one to
improve their signal, have had very successful experience with EFHW aerial
wires. It's long-term lack of general popularity among hams has always been
curious to me. I personally attribute that to the lack of a robust
commercial **remote** tuner **made for the purpose** to go at the base. An
off-the-shelf version has always been needed to serve hams who for whatever
reason are unable or disinclined to construct these devices for themselves.

None of this 50+ years of excellent EFHW experience included a 0.35
wavelength radial field. They all included very minimalist counterpoise,
including maybe one hand's worth fed against a ground rod. I remember one
just outside a window and within a few feet of the property line. I never
recommended a ground rod, but I must admit that those worked tremendously
better than what they were previously using. And it was their house, not
mine. Who knows what kind of blowback they were getting about antennas.
Back then radio could put lines through TV signals and create next door
enemies.

I will further add that an 80 meter end-fed halfwave L, and against very
minimalist ground or counterpoise, is arguably the **best** single wire
80/75m antenna for **both** DX and local contacts, and as such a real
winner for small lot situations. Especially for those small lotters where a
hundred foot radius for Mr. Devoldere's 0.35 wavelength dense 80m radial
field runs into the street and through three or four adjacent houses :>)

At my place that would be through my house, across my driveway, through
neighbor Tim's deer fence, across his driveway and into his wife's flower
garden, and toward the back into dense woods where radials are problematic
elevated or buried.

According to Mr Devoldere, that shouldn't work.

OK. Then do this:

http://3830scores.com/editionscores.php?arg=RNfmy1zEgqmmL

On the "Sort by" line set "show" to USA and click on "go"

Do a CTRL-F on K2AV. That will be 256 Q's, 18 zones and 80 countries in a
distracted, very part-time single band effort. Not bragging (I hate
bragging along with most everyone else), but if minimal counterpoise is no
good for voltage-fed antennas, then explain that score by a distracted
decent but otherwise hardly-a-genius operator.

The antenna was an 80EFHWL over a 160m FCP flipped to 80m (explained
elsewhere). That's essentially an elevated pair of 0.125 wavelength wave
radials, +/- 33 feet. Not on the same planet as a dense 0.35 radial field.
So then how does one reconcile the ON4UN ain't gonna work text with most of
a single weekend 80m DXCC in a frequently interrupted part-time effort?

This 80EFHWL was 80m dual-use-ing my 160 inverted L over an FCP, with no
loading coils or additional radiating wires. We have proven this technique
at two other stations with excellent results. More on that, later,
elsewhere.

Back in the day I had an 80EFHWL with two 15 foot buried bare wires running
away from a basement window as a counterpoise. On 80 meters and living in
New York state, taking message traffic on the Eastern Area Net, I was one
of the handful of stations able to consistently check directly into the
Pacific Area Net and forward that traffic directly to Pacific coast
stations when the normal off-net relay failed to show up earlier on 40 or
20 meters. And that was when 4 811A's running the then 1 kW **input** legal
limit could only put about 700 watts on the antenna.

I do have ON4UN's book, and have always and still do hold him in high
regard. But he, like some number of others, have been led astray by Brown's
curious assertion about halfwaves. That's the Brown from Brown, Lewis, and
Epstein of the famous 1937 RCA study on towers and radials.

That ground current format is not duplicated in a NEC4 model of a base-fed
halfwave vertical. Brown's assertions in this regard have pretty well been
discarded as a model

Hi Doug,

it works without any problems since ... I don't remember when.
But you can also buy this board with all SMT parts already soldered.

Re: [Elecraft] [OT] end-fed halfwave antennas

[Morgan Bailey]

I can echo the EFHW experiences as above but, they for me, are slightly
more noisy then a quarter wave vertical. Other than that, that is my only
objection that I have to the EFHW. Every one that I have used has been
excellent.

If you talk to Balun designs they make a 52 to 1 match box that I know for
sure will easily take 800 watts CW on 40. I ran one that way and had no
problems. With power I did use a line isolator inside the shack to protect
against common mode on the shield of the coax. I had no problems with that
set up. It worked and worked well.

I have built 2 tuner boxes for them, I bought 2 old tuners that used an L
network and rewired them to a parallel tank circuit and we, my son NS0R
have used them with 1kw and had great success. No shack problems and they
radiate like a beast because the current is high in the wire and not at the
feed point on the ground. We have used them at Field Day, WPX, Sweepstakes
as our 20 and 40 meter antennas. We both work from a city lot and have no
beams. For us, using these antennas we were able to do 1400 QSO in WPXCW
with a half hearted effort.

We use the same boxes to tune half square antennas as they also have high
impedance feed points.

I personally have used a 20 meter half square...1/4 up then 1/2 wave over
to 1/4 wire elements on 20 and this will make a quarter wave on 80 that we
used with a few radials. So we got 2 bands out of one antenna. In the half
square config on 20 meters, using it as an 80 meter made it NVIS. It did
work.

I am going to have to the me a KX3 or Kx2 some day soon. I wish I had one
now because I am heading to Maine and would like to operate there into
Europe from the coast. And, you can bet I will be taking an EFHW for ease
and portability.

[Elecraft] For Sale: Elecraft K3 and P3 combo

[PHILIP GRAITCER]

I am downsizing to an apartment and I will not have room for a station. I am 
selling a K3/P3 combination, along with microphone, interconnecting cables, and 
manuals. Here are the details:

K3 SN 696, purchased from estate and built in 2/2007
Includes:
100 Watt amplifier
ATU
General Coverage Module
KXV3A Interface
KFL3A-500 500Hz, 5 pole filter (CW filter)
Elecraft MH2 microphone

ELECRAFT P3 (panadapter) SN 1772 purchased and built by me 12/2011

The K3 has been updated with suggested factory mods thru June 2013 and it met 
or exceeded all factory standards at that time. (Elecraft letter stating this 
available.)

The equipment is in use at my QTH now (Atlanta) and works perfectly as it has 
since I purchased the transceiver in 2011. All equipment is in top condition, 
nonsmoking environment, never in the field or mobile. Selling because I am 
moving into an apartment. I would like to sell both of these together. Price 
$2300.00 including packing and shipping in the US.

Re: [Elecraft] Feature Request: improved internal keyer and CW PTT behavior

[donovanf]

Hi Tom, 



The problems I described are unique to the K3's CW PTT mode, 
you wouldn't be aware of them if you use QSK. 


My CW keying is both from Win-Test via the USB port (it works 
perfectly) and into the K3 key and PTT connectors from the K1EL 
Winkeyer (the Winkeyer works perfectly for manual keying from a 
paddle except for the unwanted long VOX delay that the K3 applies 
to the external PTT input). 


When are you coming back to a W3LPL multi-multi DX contest to 
show us how to work hundreds of 80 meter JAs again? :) I'll 
never forget that weekend on 80 meters, its never happened to 
nearly that degree again, and certainly not on both mornings! We're 
still using the same 2 element quad at 170 feet,, but we now have 
a much better receiving antenna, a W8JI/W5ZN 8-circle receiving 
array.

First, I admit to not understanding the problem! I do run QSK and VOX during 
contest and during regular QRQ QSO's. With my K3/Alpha 9500 setup, I can run 
full QSK CW up to 100 wpm and I have no PTT delay issues? I do not run with 
PTT asserted and therefore I do not witness the issues other contesters 
have.. As for N1MM's "poorly designed internal K3 keyer logic", I certainly 
have to disagree with that comment. During 'normal' contest I operate from 
28 to 40 wpm, full QSK and would go nuts if there were any perturbations 
with my K3's keying. 

A so called 'solution' to CW stuttering is to purchase and use the K1EL 
keyer. The real problem is with Windows op system wherein the CPU is often 
interrupted to do 'internal chores'; and when this happens, all I/O ports 
are shut down, which causes the CW stutter. Simply turning off the Windows 
generated sound, eliminates the stutter issue and the 'requirement' to 
purchase the K1EL keyer.

Okay, lets take Eric's lead and open an interesting thread directly related 
to an excellent Elecraft product. 



For years many of us have suffered with the odd behavior of the K3 
in CW PTT mode. There are at least two inexplicble aspects of K3 
CW PTT behavior that have forced many of us to use external 
Winkeyers rather than the poorly designed internal K3 keyer logic 
when the K3 is in CW PTT mode. 


For CW contesters, its necessary to operate the K3 in PTT mode 
to avoid unwanted VOX delay. But for some strange reason the 
K3 always applies VOX delay after external PTT is unasserted. 
I can think of no logical reason why VOX delay should be applied 
at the end of the external PTT input when the K3 is PTT mode or 
any other mode. When PTT is unasserted, the K3 should always 
immediately return to receive mode, no exceptions. 


When using the internal K3 keyer when in PTT mode, for some 
inexplicable reason the K3 behaves like its in QSK mode. The 
only way to avoid this is to use VOX rather than PTT mode or 
to use a foot switch when in PTT mode. Both alternatives 
are unacceptable. 


The band aid solution many contesters use with excellent results 
is to avoid using the internal K3 keyer and to use an external 
K1EL Winkeyer that generates both a key output and a PTT 
signal generated according to well designed Winkeyer CW PTT 
logic. 


Why can't the K3 implement logic similar to the Winkeyer to 
generate the equivalent of "Winkeyer PTT" when using the K3 
internal keyer when the K3 is in PTT mode?

Re: [Elecraft] [OT] end-fed halfwave antennas

[Irma Linas]

EFHW is a great antenna. It works but only if tuned correctly. Bad news is
 it would be difficult to do the tune job for any ATU, even the Elecraft,
due to the very high impedance ( up to the 5kohms). Please read everybody
the aticles by the EFHW guru here : http://www.aa5tb.com/efha_wrk.html.
STeve explains very clearly the whole theory behind the EFHW, the length of
"counterpoise" etc.

I have built and used many of the EFHW antennas in different configurations
, including usage of the loading coils in the multiband operations in order
to make the wire  shorter on the low bands. The tuner is the simplicity in
itself if used on qrp levels. For the higher power levels the
coil/capacitor choice must  be high ( very high!) RF voltage- proof.

Surely , the tuner , as good as Electaft makes, and the random lenght NON
resonant wire is the excellent solution for the portable work but then you
need a kind of ground whatever you can get at hand. Have tried it for many
years with the Elecraft T-1 tuner with great success working 5 W from the
hotels accross Europe tuning anything I could- window frames, rain water
pipes, random pieces of wire, :)...

Re: [Elecraft] Tracking Elecraft Feature Requests

[Phil Hystad]

Managing feature requests is traditional with software products.  I worked in 
software for 45
years prior to retirement and even started a company where enhancements to the 
various
products were very important to our customer base.

We had a feature request web site that we hosted and licensed customers had 
access to this
web site.  Prior to the web site, from 1970s to 1990s, we managed feature 
requests by paper
in the same manner of a customer submitting a bug report and reviewed such 
features with
customers during the annual user group meetings.

Given that radios, and in particular Elecraft gear, is almost just as much a 
software system
as hardware that such feature request management should be encouraged by 
Elecraft and
accessed via their http://elecraft.com web site  although not necessarily 
hosted by elecraft.com
since I am not sure how they manage their web site.  Access should be to anyone 
who has an 
Elecraft rig identified by serial number since I think being assigned login 
credentials should
be granted to owners only.  Yes, I know that there are Elecraft productst that 
do not have
serial numbers but they also are likely not to be generating feature requests 
anyway.

My two-bits.

[Elecraft] KPA500 Fan Noise

[j...@kk9a.com]

Is loud fan noise common with smaller solid state amps?  I have read
complaints about the SPE Expert 1.3k loud fan noise and the new Flex Power
Genius sounds pretty loud in the demo video. I have the fan on my KPA500
set to 4 (if I recall correctly) and it is pretty quiet however setting it
one speed higher and it becomes significantly louder and quite annoying.
While I rarely use this amp I would still see a quieter fan, a setting
in-between 4 and 5 or a larger heat sink as a nice option. I wonder if the
Acom 600S has fan noise issues, it is physically larger and I have yet to
read any such comments.

Re: [Elecraft] Tracking Elecraft Feature Requests

[Harry Yingst via Elecraft]

It should be hosted by Elecraft.


I have another radio (mcHF) that the developers take request and implement 
changes, it's actually a nice feature since you can see what is being requested 
and to a degree the status of the request.

Joe,

Why limit it just to list subscribers? Surely there are those out there who
may want a specific feature, but are not part of this list and don't wish to
be (for whatever reason) but may still own an Elecraft item?

Where are you planning to post these? Who's going to host whatever website

It would be nice if we could track Elecraft feature requests in a more
structured manner.  The same feature requests come up over and over again. 
We often hear, "Elecraft will never develop feature X unless N users ask for
the feature."  Rather than having subscribers respond to the Elecraft email
list saying, "Count me in", "Me too", ... why not allow subscribers to
express interest in a proposed feature by adding their name / callsign to a
"feature logbook"?  One logbook per feature request.  Logbooks would be
organized (tagged) by Elecraft product.  Each logbook would include fields
such as:

    Created by
    Created on
    Abstract
    Description
    Applicable Elecraft products
    Disposition 
    Disposition updated on
    ...

We wouldn't need to burden Elecraft with maintaining the logbooks.  We could
designate a few admins.  We would need a means of authenticating a
subscriber (e.g., Elecraft email list username / password, QRZ.com username
/ password, ...).  Any subscriber could create a new feature logbook or an
admin could create a logbook on a subscriber's behalf.  An admin would
update a logbook disposition to reflect feedback from Elecraft (e.g.,
"planned for release R", "rejected due to technical limitation T", "under
consideration", ...).  An admin would reconcile duplicate / overlapping
logbooks.  Subscribers would only express interest in a proposed feature
(not disinterest).  Comments, questions and concerns regarding a proposed
feature would be reconciled through the Elecraft email list and reflected /
updated in the logbook description by the Creator or an admin.

Thoughts?

[Elecraft] Early Morning QRPing on 80 Meters

[Pete Meier]

Hi all,

While Ed AB8DF is on vacation I am stepping in until his return at the end of 
the week to keep this great thing going and growing.

Today was an OK day as I worked 1 station from my qth in Manitou Springs, CO.
I am running a K3 at 5 watts into an end fed half wave up about 30 feet.
Conditions were not the best but I enjoyed the QSO.

I worked:
K5PD   Dallas, TX


Like Ed I will be hanging out on 3.560 most weekday mornings from 1200z to 
1300z 
while I have my morning coffee. Just might be the way to survive the sun 
spot lull.

Re: [Elecraft] Feature Request: improved internal keyer and CW PTT behavior

[donovanf]

Hi Wayne, 


As Brian pointed out, one of the design issues is that in some 
situations -- foot switch usage comes to mind -- the external PTT 
will be inadvertently un-asserted before the operator stops keying 
or stops speaking in the SSB case. The design must properly 
handle premature external PTT de-assertion. 


I recommend taking a look at the behavior of the K1EL Winkeyer. 
Its user community helped its firmware developer achieve highly 
optimized CW keying and CW PTT behavior.

[Elecraft] Backpacking antennas

[Wes Stewart]

The recently closed thread about the so-called end-fed-half-wave (EFHW) antennas 
elicited a lot (too much in Eric's eyes) of discussion, much of it confused and 
confusing.


To keep this Elecraft related, I'll throw in something that Wayne wrote in 
another thread about the subject of this thread:


"For antennas, assuming you have trees or other ad-hoc supports available, you 
can use a random-length wire for both the antenna and ground. Toss one wire in a 
tree (etc.) and lay the other on the ground. The KXAT3 ATU will tune a 25' or so 
wire on 40 meters and up. Use twice that length to also get down to 80 and 60 m. 
You can connect the wires to a BNC-to-binding post adapter, like our model 
#BNC-BP. For wire, I recommend #26 "Silky" from the Wireman."


In the EFHW thread I made, among others, the following comment:

"This thread is a long one and frankly I didn't follow it at first, but a little 
research says that the OP was interested in bringing a coax feeder directly into 
the radio from the end of a wire.  He incorrectly called the coax a 
"counterpoise", instead of an extension of the wire which it really is, because 
it's going to radiate, but never mind that.  In this case, the antenna is a 
"sloper" whether it is called that or not.  If one end is higher than the TX 
then there is a vertical component to the geometry and the radio chassis is the 
"counterpoise.""


I've since heard privately from him (and will answer, Dan) but to help clarify 
this subject I'll turn to the late LB Cebik for help:


http://www.antennex.com/shack/Dec06/cps.html

I think his Figures 5 and 6 are particularly appropriate, but the whole piece is 
informative.

1. I'm trying to reduce spam.  2. I'm looking for an element of traceability
/ accountability.  We want to discourage users from expressing interest in a
proposed feature on another user's (or users') behalf.

We'll need to work out the technical details.  At this point, I'm simply
trying to gauge interest in the concept.

Re: [Elecraft] Feature Request: improved internal keyer and CW PTT behavior

[donovanf]

Hi Brian, 


The PTT problem I described is that the K3 adds a long delay (the 
VOX delay, much longer than 5-10 milliseconds) after the external 
PTT is dropped. I can't explain any rationale for adding VOX delay 
after PTT is dropped except for a firmware design error. VOX 
delay is applied to PTT in every operating mode, even in SSB 
VOX mode. 


Fortunately VOX delay is not applied when using computer keying 
via the USB port.

Frank, 
Pardon my ignorance on this issue if the below is off target. 
The asynchronous nature of an external ptt appears to be a problem. 
Suppose the K3 is in the middle of a long 100 watt dash and the external ptt 
signal is dropped. It clearly takes some time for the RF tail to drop to zero. 
One would seem to need to add some delay time for this to happen. To avoid 
clicks one wants a shaped tail. I dont see how the K3 can immediately go to RX. 
How fast a turn off and go to RX action do you want? Is the normal 5 ms tail 
fast enough? 

Of course if Winkey logic is programmed within the K3 the asynchronous problem 
goes away. 

The adjustable TXDELAY issue where the CW gets QSD with a setting more than 8 
ms is an issue that has existed from day one. People started complaining about 
it on day 2. Elecraft has know about it for a long, long time. From what I am 
able to glean about the problem is that it may be really difficult to fix. 
Apparently the timing has to be fixed in many places in the code to produce 
good CW at all values of TXDELAY. If the fix were a simple one, it would have 
been fixed years ago.

[Elecraft] Tracking Elecraft Feature Requests

[Joe Stone (KF5WBO)]

It would be nice if we could track Elecraft feature requests in a more
structured manner.  The same feature requests come up over and over again. 
We often hear, "Elecraft will never develop feature X unless N users ask for
the feature."  Rather than having subscribers respond to the Elecraft email
list saying, "Count me in", "Me too", ... why not allow subscribers to
express interest in a proposed feature by adding their name / callsign to a
"feature logbook"?  One logbook per feature request.  Logbooks would be
organized (tagged) by Elecraft product.  Each logbook would include fields
such as:

Created by
Created on
Abstract
Description
Applicable Elecraft products
Disposition 
Disposition updated on
...

We wouldn't need to burden Elecraft with maintaining the logbooks.  We could
designate a few admins.  We would need a means of authenticating a
subscriber (e.g., Elecraft email list username / password, QRZ.com username
/ password, ...).  Any subscriber could create a new feature logbook or an
admin could create a logbook on a subscriber's behalf.  An admin would
update a logbook disposition to reflect feedback from Elecraft (e.g.,
"planned for release R", "rejected due to technical limitation T", "under
consideration", ...).  An admin would reconcile duplicate / overlapping
logbooks.  Subscribers would only express interest in a proposed feature
(not disinterest).  Comments, questions and concerns regarding a proposed
feature would be reconciled through the Elecraft email list and reflected /
updated in the logbook description by the Creator or an admin.

Thoughts?

Re: [Elecraft] K3 with switching power supply??

[Joe Subich, W4TV]

I have no disagreement with anything you've said, particularly
keeping the pass transistor mounting refreshed and relocating
the diodes to a heat sink if your particular RS-35(M) uses the
stud mounted diodes.

However, the 723 has a relatively high dropout threshold.  Other
regulator topologies, like that in the BWC Electronics article,
provide lower dropout and allow the pass transistors to be mounted
without insulating hardware providing for lower heat dissipation,
more efficient cooling and more reliable operation.  In addition,
the other topologies can also provide improved transient response
(resulting in improved IMD, etc. from the transceiver).


For a any linear PSU, even a small fan wafting air over the
heat-sink will make a world of difference too, resulting in a much
cooler PSU that is much more reliable as a result. If you don’t like
the continuous sound of that, fit a thermal switch to the heat-sink,
say 50'C, to turn the fan on when it gets hot...


Yes, a fan is certainly useful - particularly for RTTY or contest
service.  However, I'd suggest a dual speed scheme with a constant
low speed (quiet) that switches to full speed at say 40C.  One does
not really want the heat sink (and by extension the pass transistors)
to exceed 50C.  The Astron supplies have been known to reach 85C or
more with "brick on the key" modes - certainly not good for the long
term health of the supply.

 > I am on the way to change my old Astron RS35M power supply

Why would you change out an Astron RS35M?  Unless you need to
make the K3 station portable where the weight and size of the
Astron is an issue, the RS35M will be both much more quiet and
much more reliable than any switcher.

Even if the Astron is getting a little unreliable, an overhaul
(replacing the diodes, pass transistors and possibly filter cap)
is likely to be more cost effective than purchasing a switcher.

For repair/overhaul information see:


or for a more in-depth modification/overhaul that replaces the 723
regulator see: 


73,

... Joe, W4TV

There is absolutely nothing wrong or bad about the 723 regulator.  But
there are a lot of badly designed units using that IC out there.  The
designers did not read (let alone fully understand) the data sheet.  And
then not helped by the physical layout people, who don't appreciate the
effect "inappropriate" wire routing can have on a regulator with a high
loop gain. Don't blame the device for poor product design.

What does go bad over time with most "Ham market" linear PSU's, is not
so much the main cap (often too high a value) diodes or pass transistors
(unless this next issue has happened.)

High value reservoir caps can overly stress the rectifier diodes, and
transformer.   Ripple is to be expected across that, and is what the
regulator is there to remove...

Anyway.  The thermal interface between the pass transistors and heat
sink often deteriorates, not helped by the usual sloppy build quality in
the first place.  (I've even seen pop-rivets used to mount regulator
pass transistors!  BAD BAD BAD!)

Same for the main bridge rectifier if that is heat-sink mounted as
well.If it is not, consider moving it to the heatsink, or fitting
one to it if there is room.

The cooler you can keep a semiconductor (within reason) the longer it
will last.   Wide variations of temperature are also bad, often for
where the leads are connected to a PCB, if not using flexible wire
resulting in failed solder joints.   Always "kink" the lead with a z
formation for mechanical stress relief, it'll last much longer as a result.

Power transistors with sockets too, can suffer intermittent lead
connections over time, due to thermal cycling and the minute repeated
relative movement between lead and socket, usually damaging the plating
on the semiconductor lead, resulting in bad connections.   Replacing the
socket will not cure that.

Dismantle, clean and re-apply fresh compound or thermal interface pad.
Use fresh insulating (clamp) washers too if needed.   Most of all, do
not over-tighten those device mounting screws.   No, I can't quote a
torque, you'll have to research the matter, and consult the device
makers data sheet, if you can identify the devices that is...

Re solder any joints that appear a little suspicious around the high
power devices.   Replace any suspect socket connections by removing them
and soldering the wires to the device leg’s directly.  (If the device
legs plating is not badly corroded, if so, replace the device too.)

The same holds true for the pass transistor 

[Elecraft] KREF3 Output Level Mod

[Russ]

All:

Since I'm digging into the K3 to add some options, I have decided to make the 
output level mods suggested for the KREF3 board when used with the KSYN3A 
synth. Sub-rx and internal transverter.

Just wondering why the R12 (main rx ref feed) swap from 150 ohms to 51 ohms and 
not the R10 sub rx feed resistor too?
Is the main rx feed double terminated with the addition of the transverter, 
thus needing additional drive?

Tnx,
Russ KD4JO

The band aid solution many contesters use with excellent results
is to avoid using the internal K3 keyer and to use an external
K1EL Winkeyer that generates both a key output and a PTT
signal generated according to well designed Winkeyer CW PTT
logic.


Why can't the K3 implement logic similar to the Winkeyer to

easy physical fit internally, and a external  IF pass band filter for a 
clean signal no matter what kind of signals are present in your shack.
Not a area of your receiver where you want to be hacking about. Just 
saying.

Ken,

Sorry, but I do not.
There is a ham in England who produces a buffer amplifier that can be
used, but I cannot recall who.
If you ask on the reflector for a Clifton Labs Z1B replacement,
you may get some hits.

There is absolutely nothing wrong or bad about the 723 regulator.  But
there are a lot of badly designed units using that IC out there.  The
designers did not read (let alone fully understand) the data sheet.  And
then not helped by the physical layout people, who don't appreciate the
effect "inappropriate" wire routing can have on a regulator with a high
loop gain. Don't blame the device for poor product design.

What does go bad over time with most "Ham market" linear PSU's, is not
so much the main cap (often too high a value) diodes or pass transistors
(unless this next issue has happened.)

High value reservoir caps can overly stress the rectifier diodes, and
transformer.   Ripple is to be expected across that, and is what the
regulator is there to remove...

Anyway.  The thermal interface between the pass transistors and heat
sink often deteriorates, not helped by the usual sloppy build quality in
the first place.  (I've even seen pop-rivets used to mount regulator
pass transistors!  BAD BAD BAD!)

Same for the main bridge rectifier if that is heat-sink mounted as
well.If it is not, consider moving it to the heatsink, or fitting
one to it if there is room.

The cooler you can keep a semiconductor (within reason) the longer it
will last.   Wide variations of temperature are also bad, often for
where the leads are connected to a PCB, if not using flexible wire
resulting in failed solder joints.   Always "kink" the lead with a z
formation for mechanical stress relief, it'll last much longer as a result.

Power transistors with sockets too, can suffer intermittent lead
connections over time, due to thermal cycling and the minute repeated
relative movement between lead and socket, usually damaging the plating
on the semiconductor lead, resulting in bad connections.   Replacing the
socket will not cure that.

Dismantle, clean and re-apply fresh compound or thermal interface pad. 
Use fresh insulating (clamp) washers too if needed.   Most of all, do
not over-tighten those device mounting screws.   No, I can't quote a
torque, you'll have to research the matter, and consult the device
makers data sheet, if you can identify the devices that is...

Re solder any joints that appear a little suspicious around the high
power devices.   Replace any suspect socket connections by removing them
and soldering the wires to the device leg’s directly.  (If the device
legs plating is not badly corroded, if so, replace the device too.)

The same holds true for the pass transistor (and their drivers) emitter
ballast resistors.  Check their condition and connections.

No emitter ballast resistors?   Bad design...

For a any linear PSU, even a small fan wafting air over the heat-sink
will make a world of difference too, resulting in a much cooler PSU that
is much more reliable as a result.   If you don’t like the continuous
sound of that, fit a thermal switch to the heat-sink, say 50'C, to turn
the fan on when it gets hot...   (Or based on PSU output current...)

73.
