For Jerry - there are other reasons for employing an ATU in the shack - e.g., 
using open wire line feed line from the antenna back to the xmtr.

Folks - In the interest of relieving our list readers from severe single topic

While an interesting topic with lots of good comments, its had a -huge- number 
of postings. It is time to give it a rest.

The real problem is not enough bits.  DSR proponents continue to ignore
the sensitivity vs. overload trade-off.  They tout their "top of the
list" IMD performance and "multiple slice receiver" capabilities while
completely hiding the fact that those items can only be accomplished by
reducing sensitivity some 30 dB compared to a conventional superhet
receiver in the presence of strong signals.

Re: [Elecraft] Elecraft Utilities

[Eric Swartz - WA6HHQ, Elecraft]

Agreed.  Let's end the thread for now. (feel free to email with any questions.)

I apologize, but open sourcing the utility would create a number of problems and 
significant extra support expense that we can not afford. Improper use of that 
proprietary interface can certainly brick the radio, and in some cases actually 
damage the hardware. That's something that would not be a warranty repair..


We are not staffed to develop and support utilities for a wider range of 
hardware and operating systems right now. We're already support multiple 
versions of Windows, Mac OSX, and some versions of Linux. That's a lot more than 
most radio companies. Continually expanding beyond that also becomes 
exponentially expensive in a specialized market the size of this one.


That's likely the max we can do in the near term as we're primarily focused on 
designing new cool products for everyone. I'm not ruling out other OS utilities, 
but its likely nothing will appear near term as we have our hands full on other 
projects.


Feel free to email me directly with any questions.

W5QD et. al.,

 Ken is referring to the following message, which essentially requests a 
simple command-line firmware loader program.  Note that this is NOT a request 
for DNA level access to the radio's internals.
 The communication protocols for most of the Elecraft radio functions are 
described in the public documentation, enabling people to write their own code 
for most functions.  The firmware loading protocols, however, are not. The only 
way to update the firmware (not generate our own!) is to download and run 
platform specific GUI applications from Elecraft.  For most users running 
Windows or MacOS, this is fine: virtually all of these users expect GUI 
software, have their computers directly connected to their radios, and aren't 
aren't running on unusual computer hardware.
 For those of us running Linux (or even more obscure operating systems), a 
GUI application that only works on x86 machines that are directly connected to 
the radio is awkward.  My laptop and all of my shack machines are ARM based, so 
when I need to upgrade my K3, I need to extract it from all of its cables and 
haul it over to my x86 work machine.  My work machine is running 64bit linux, 
while the Elecraft tool is 32bit, so I also need to install 32bit versions of 
several libraries to run it. Similarly, all of my radio gear at home is 
actually hooked to a serial-to-ethernet device, which is great for all of the 
software I use, but not fine for K3Util, which expects to talk specifically to 
a directly connected hardware serial port.
 There are several approaches to solving this problem.  The first is to ask 
Elecraft to provide more versions of their software: can I get an x86_64 build? 
 ARM7 please!  Actually, I use my Android for everything ... can I get an 
Android app?  Fortunately, we recognize that Elecraft is a /radio/ company, 
/not/ a consumer software company, and we don't want to ask them to spend time 
supporting dozens of firmware loaders.  Ideally, we would like to see or, with 
access to the protocol documentation, develop an open-source library for 
updating the firmware. Then we can build our own firmware loaders for whatever 
platforms we choose.
 Recognizing that this may be asking for proprietary and/or licensed information, 
Bruce has suggested a middle ground -- offer a simple "glue" interface (a 
command line firmware loading tool) that would be much simpler for Elecraft to build for 
lots of different platforms and would be more in line with the linux philosophy of 
starting with light weight command line tools, and adding far more difficult to develop 
and maintain GUIs on top as desired.

 Perhaps a simpler option would be to offer a library or command line tool 
in a portable format that still obscures the proprietary protocol 
implementation.  Java is a good candidate for this, as there are Java

Ed's approach is one that I've used from time to time, but let me add one

caution. Be very careful to avoid nicking the wire. It's very easy to do
with fine wire most often by an accidental press where you start removing
the enamel.

The nick will create a weak spot that may fail later. And with that we could
segue back into the question of breaking wires off in gear that is subject
to vibration.

I know that Mychael (the toroidguy) uses a solder pot. He's often grumbled
to me about finding one what works well over time. AFAIK he has compromised
on a fairly inexpensive pot that he ends up recycling after a year or so of
use when the heater or thermostat fails. Also one needs to keep the dross
(burned enamel, etc.) that covers the surface of the solder cleaned off so
it doesn't coat the wire as you remove it. Don't forget that you need a lump
of solder to melt in it too.

I always figured the enamel should be removed.  I just scrape them with a
small razor knife which leaves the copper bright and ready for tinning.
Melting the enamel with my solder iron results in a messy glob on the iron
and not a very clean lead.  I don't own a solder pot but could see that
would work except for contamination of the solder if you do many.

I am mostly winding air coils for VHF equipment, so its what is normally

Oops, my apologies: one of those was me, my excuse will have to be that it
was in 1973 and I guess those memories are no longer what they used to be!

I probably mixed that up with my code practice tapes, which definitely did
have 4 letter code group parts

Exactly!  Yet some report, even here in the past few days, that their ham
Morse exams were random character code groups.  Thanks for information to
the contrary that can be neither doubted nor disputed!

One could discourse all day on what "proper" is in this context without

When the only stateful levels were strictly on and off, and the rise and
fall transition time amplitude curves were set by a resistor and a
capacitor, one could make some simplifications in the discussion.

Today, often, as in the K3, the rise and fall times and shapes of CW are
DATA which goes DIRECTLY to RF via a DAC. For these the nature of the rise
and fall curve is not governed by a charge/discharge time of analog
components, but rather by whatever function generated the waveshape data,
which is stored, *read* as needed and never generated real time. In many
cases it is far more accurate to say that the rise and fall of a baud is
INTRODUCED, rather than the signal is keyed.

If the rise and fall data curves used for "keying" vary their "sharpness"
according to speed, then the description bandwidth increases by speed
certainly does apply. But if not, the bandwidth is governed by the pulse

I was just looking at the P3 display of some traditional BC band stations
around here. A 30 over 9 station at 1490 kHz fills up 1480 to 1500. Using
the K3's AM-S mode on USB side the S9 station at 1500 kHz is clearly
intelligible, but the standard demodulation for 1500 is obliterated by the
1490 station. That ain't your granddaddy's AM out there any more. That's
some really complicated stuff that completely fills up +/- 10 kHz and
clearly not done the same from station to station. I'm going to save
googling that for a free evening when I don't have something broken to fix.

There is so much stuff I was taught by my WCTT Chief Engineer Elmer that I
am having to set aside.

No Jim, you are wrong here. CW is a carrier modulated by a digital
(on/off keyed) signal of a given (baud) rate.  That keying will
generate sidebands +/- the baud rate *just like FSK* or even AM which
can be observed on a spectrum analyzer.  The ITU formula is quite
accurate in terms of the actual bandwidth for signals with *properly*
*shaped keying*.

Again, the excess bandwidth from improperly shaped keying signals
(clicks) and/or amplifier distortion is something else.

Re: [Elecraft] IC-7300 video - things to come

[Eric Swartz - WA6HHQ, Elecraft]

As a private pilot I fly with a Garmin GTN750 touch-screen GPS NAV/COM in a 
Cessna 182. Its powerful and quite intuitive to use, even in turbulence. (They 
included ridges along the four screen sides when needed to steady your hand.) It 
actually reduces the amount pilot load and time spent looking inside the cockpit 
when used properly - Though you can certainly abuse it dangerously if you treat 
it like a video game and forget to look outside the cockpit..   I wouldn't go 
any other way now.   (And I came from a full-on knobs based flight environment 
prior to that.)


There are great touch-screen avionics implementations and horrible ones. The 750 
is a good one and world's above many others.


I think for future ham radios and similar product designs, what will be 
important is meshing the correct balance between traditional hard knobs and 
buttons with unique touch-screen features (display and input). The overall goal 
should be to balance the user interface between the touch-screen and 
knobs/buttons for ease of use without unintended confusion while adding unique 
touch-screen display and easy to use input features.


As a side note - I use the remotehams.com free remote software with the 
K3/0-Mini and a laptop to remote my home K3S, KPA500 and Rotor. Interestingly, 
the little h/p satellite 360 convertible laptop/tablet has a touch screen, which 
I use for many functions like rotor control, amp control/status etc, but I like 
it combined with the K3/0-Mini's knobs and display for regular intuitive use, 
versus using it only for 100% computer based remote control.

Re: [Elecraft] K3S audio board for K3 upgrade?

[Eric Swartz - WA6HHQ, Elecraft]

Hi Ron,

That review of the K3 audio by Rob Sherwood was on a very early K3. We quickly 
addressed the high freq harmonic issues (most of which were above 4-5 kHz and 
were more than 50-60 dB down) with a K3 DSP board revision that included a 
change to a beefier low ESR power supply filter choke feeding the audio amp and 
the addition of an audio LPF that rolls off above the DSPs max output of 4 kHz. 
We made even more audio improvements to the new K3S DSP board's audio chain.


On another note, Rob has run spectra on the newer K3S DSP and he has noted it is 
substantially improved over the first K3 he tested almost 7 years ago.


One thought for those using the 2.7 or 2.8 SSB filters. Try reducing the DSP 
bandwidth to 2.4 kHz or so, and shifting the center freq. down 100 Hz.  Many 
other radios have a 2.4 kHz SSB filter, and while it does restrict the audio 
fidelity as compared to the 2.7/2.8 kHz filters, the reduction in the upper 
cutoff to 2.4 kHz reduces the amount of high frequency band noise and 
interference, which may account for what some construe as a 'smoother' sound.


Also note that the stock 2.7 kHz filter has a much slower roll off than the 
optional 8 pole 2.8 kHz filter, and as a result may hear more higher frequency 
RX components.


Lastly, try listening with our new external SP3 speaker for the K3S and K3. It 
has an engineered audio response for a very clean and 'smooth' flat response, 
without major resonances.   :-)

Eric

The sounds being described are probably not just related to frequency
response, but to any type of harmonic, intermod or digital distortion, or

This was referenced by Rob Sherwood in an early review of the K3 and
demonstrated with an audio spectrum analyzer.  A CW tone with these
characteristics might be described as "raspy", "brassy", "busy", or with
some other term audiophiles like to use, and in any case, would likely lead
to fatigue.

If this is the case, equalization may mask it but won't fix it, and could
make the problem worse.

Re: [Elecraft] 10 MHz external reference - GPSDO

[Eric Swartz - WA6HHQ, Elecraft]

Hi Ed,

Minor note on our TCXO part numbers:

The tighter temp stability TCXO (0.5 ppm typical) is actually Elecraft part 
number "TCXO3-1". This is the p/n that shows on the K3S order page and in the 
K3S kit manual as an upgrade.


The standard TCXO (5 ppm) supplied with the K3S and K3 has the part number 
"E660033".


Regards,

Eric

TCXO's use temperature compensating components to try to keep frequency 
stable.  They work fairly well if you are at lower frequencies or not 
multiplying an LO 18 times.  Better is the OCXO (which uses a heater inside an 
insulated "oven" to better keep temperature effects isolated).


The EXREF utilizes the better stability of 10-MHz sources to correct the drift 
of the TCXO.  I does that at a fixed interval in between which both TCXO-1 and 
TCXO-3 will drift.  Per Elecraft's specifications on page 8 the TCXO-3 is 5 
times more stable than the TCXO-1.  I have no idea over what time interval the 
specs are cited, but most assuredly its more than 4 seconds.

[Elecraft] Elecraft email List Official Guidelines 2016

[Eric Swartz - WA6HHQ, Elecraft]

Elecraft eMail LIST GUIDELINES 2016

For those of you who are new to the list, (and for those of us who have rapidly 
failing memories) here is a quick list of things to remember when posting to 
this list. Please save this for future reference.


The most important thing to remember is that this is a hobby - Let's have fun!

The PRIMARY purposes of this list are to provide a polite and enjoyable forum 
for discussing Elecraft products, share mods, new ideas, feedback to Elecraft, 
share experiences using our products, troubleshooting ideas etc.


The Elecraft email list server (reflector) is provided to further the discussion 
of Elecraft products and related items. It serves as a forum for the discussion 
of both technical and operating topics including product features, construction 
and debug problems, sharing your enthusiasm and impressions from using our 
products and more general ham radio related topics of interest to our customers.


(Please -strongly- resist the urge to reply to an OT topic once it has gone to 5 
posts. Once it hits ten posts do not reply at all (go off list if you feel the 
urge to continue.) Also, please do not try to always get the 'last word'..



1. YOU MUST BE SUBSCRIBED to the [Elecraft] list TO POST to it. (This is done to 
stop advertising spammers from hitting the list.) Any postings sent to 
elecraft@mailman.qth.net by addresses different from the exact ones it shows as 
subscribers will be rejected.


This includes alias (forwarded) addresses like w1...@arrl.net. If you use an 
alias to subscribe you must have it as your from: and return address too. 
Subscribing with w...@arrl.net from your physical address of j...@aol.com will 
allow you to receive postings, but your postings to
the list will be rejected if their from: and reply to: address does not match 
your subscribe address..


Go to http://mailman.qth.net/mailman/listinfo/elecraft to subscribe and to 
change your list preferences. To unsubscribe or to change your list preferences 
(digest, no mail on/off etc.), scroll to the bottom of the page and log in with 
your subscribed email address and the password that was sent to you by email 
when you subscribed (and sent to you each month).



2. If you want to provide an attachment, .JPG picture or other large file for 
use on the list, first post it to your personal web page and then post a link to 
its address in an email to the list. The list strips all attachments to prevent 
viruses from propagating and to keep the archives at a reasonable size.



3. Top posting is the official standard for this list, and its especially
important for those of us who also read our email on smartphones, iPads etc. 
Scrolling though a long thread before getting to the reply text is difficult on 
these devices and costs everyone a lot of time.


Reading the response first, at the top, is a huge time saver, especially when 
you have to read hundreds of emails daily as we do here. We really appreciate 
your adherence to this.


Please also delete -all- footers and as much of the prior email text as possible 
when replying to cut down on overall email size. Please keep the amount of 
copied text from previous posts to an -ABSOLUTE MINIMUM- in your replies.



4. EMAIL OVERLOAD:
If you are overloaded by the volume of individual messages on the list, You can 
view the daily Elecraft list messages for each month in web format at: 
http://www.elecraft.com/elist.html . These archives are updated hourly and list 
postings by subject. (the Nabble archive looks very useful.) Just click on the 
ones you are interested in to read.


You can also set your Elecraft list email preferences to 'no mail' delivery, 
which still allows you to post to the list when reading via the digest.


You can also change your subscription to the DIGEST version, which sends you a 
single compilation each day.


To change your email list options or to subscribe / unsubscribe, go to:
http://mailman.qth.net/mailman/listinfo/elecraft Scroll to the bottom of the 
page to log into your preferences page and set your mail options to 'no mail'.



4a. Please make an effort to keep list volume under control by resisting the 
urge to post a comment on every long discussion thread (CW, Soldering etc.) With 
thousands of list subscribers volume can quickly get out of control if everyone 
feels the need to comment. While we do not overly restrict the subject matter on 
this list, please remember that its primary focus is on Elecraft products, and 
their use. Many people rely on it for pointers on building, using and 
troubleshooting their rigs. Other ham Radio topics are OK, but please keep the 
posts on non-Elecraft topics under control.


4b. *** When emailing about a specific rig or option, please add the rig/option 
name(s) to the first part of your email subject line. (K1, K2, K3, KX1 etc.) 
This will be a huge help for those experiencing email overload and will allow 
automatic filtering based on subject line.

Re: [Elecraft] K3s Odd sound vibrations Edit - Hypothesis, Steps, Conclusion, and Request.

[Eric Swartz - WA6HHQ, Elecraft]

Make sure you use non-acidic silicon glue that is compatible with PC boards to 
do this.


Other types can degrade traces etc on the board.

change the spot frequency around I am able to find harmonic spots that make

to put a dab of silicon on the ferrites to stop the rattle.
Easy fix. The result seems to depend on where you like the monitor frequency
to be.

I like Howard's suggestion to go with an external speaker or use a headset.
At this point it's fixed for my use.

Another possible cause...  If you have the 100W PA option, you MIGHT be
hearing ferrite beads rattling inside the PA module.  I don't know why they
are loose on the wires, but they are and you can hear them rattle when you
shake the module prior to install.
The Assembly Manual references them and says the rattling is "normal".

IF they are the source of your buzzing, the module will need to be
disassembled and the ferrite beads fixed in some fashion so they don't move
and/or make contact with metal enclosure, shield, et al.

Hi, I thought I had the sound issue licked with the loose case screws
but I still hear the buzz. I believe I found the issue and it's NOT
the speaker (well I don't believe based on my findings).

  


Hypothesis:

I strongly suspect loose transformer cores are the cause of the
buzzing that are especially louder at different harmonics.

Re: [Elecraft] CQ WPX RTTY Contest

[Eric Swartz - WA6HHQ, Elecraft]

Hi Bill,

If the P3SVGA is set for displaying K3 decoded digital or CW text, another 
external text display program (rumlog, K3 Utility text window etc.) that 
accesses the K3's decoded text over the serial or USB command interface can not 
be running and displaying the decoded text at the same time.  (The P3 with 
P3SVGA gets this data over the same serial path the external program does and 
the K3 flushes out the buffer after each read.)


This is a one application at a time interface.  Running a second app 
simultaneously will cause the loss of text you are experiencing.

Eric

Thanks to some off list advice, I think I have tracked this problem down. It 
doesn't appear to be RUMlogNG because it also occurs with the K3 utility. 
(Note: I found thi problem before communicating with Tom DL2RUM.) Here's my 
message to support describing the problem:


When running the K3 utility (Mac version, but the problem might also occur 
with Windows and Linux), with the terminal window open, and having the P3/SVGA 
data display turned on, both the P3/SVGA and the terminal window lose 
characters during RTTY decode. The correct characters appear on the K3 display.


Turning P3/SVGA data display off clears up the characters in the terminal 
window, and switching to one of the other windows in the K3 utility clears up 
the problem with the P3/SVGA.


Simular problems occur using RUMlogNG's contest mode for RTTY.

Given the easy workaround, this problem isn't super high priority, but if it 
will be with us for a while, people should learn about the workaround.

Re: [Elecraft] abject buffoonery

[Eric Swartz - WA6HHQ, Elecraft]

Folks - We're drifting a bit far OT from our usual focus. As this is a repeating

Hi All,

This is a major reason why I have almost totally abdicated usage of SSB, and 
stick to CW, which is my preferred mode anyway.  There I can participate in 
relatively nonsense free and enjoyable rag chews with others.  About the only 
time we get substantial craziness on that mode is when there is some sort of 
DXpedition going on.


For the most part, I don't think that, for the most part, these clowns (I 
actually have a much stronger, more profane term for them!) can even copy CW.  
So, it's not much "fun" for them to jam conversations they can't even 
understand.  I also think that alcohol has a great deal to do with what you 
hear on 75 meters. Sometimes it is completely obvious!


I don't know about the rest of you, but I would be willing to pay a 
significant additional fee, and every year if necessary, if FCC could then do 
serious enforcement on the bands.  I know right now they don't have any real 
staff to do it.  You wouldn't even need a particularly high percentage of 
successful enforcement situations to generate substantially beneficial 
results.  Just having a real threat that such actions might be successfully 
captured could be enough to put "the fear of God" into a significant number of 
perpetrators.  Right now, there is little, if any, risk of being caught. So, 
it is like having speed limits, but no enforcement whatsoever!


A lot of people say "just ignore" the incidents.  I tend to agree with that, 
since confrontation only excites the perpetrator--particularly if alcohol is 
involved  You can't argue or reason with a drunk!  I do think recordings 
could be helpful, and if you have the capability, a little "DFing" might add 
some useful info if there was any place such info could be collected for 
further analysis.


I think every ham radio club in the country should take this issue seriously.  
Not only should members "pledge" to avoid such conduct, they should also agree 
to be actively involved in identifying it.  It's hard to believe that a number 
of these perpetrators aren't close enough to someone else that they couldn't 
be better identified.  We need to take some responsibility ourselves for 
trying to reduce such infractions. That doesn't mean direct confrontation, but 
serious information could be useful to authorities.


Just my thoughts.

Dave W7AQK

I am changing around my modest antenna configuration now.  I have been

What balun, homebrew or commercial, if any, should I use?  I almost

K2/100 and KAT100 here.

I am changing around my modest antenna configuration now.  I have been
using the K2/100 with my AH-4, and now wish to use the KAT100 with
balanced feedline antennas.

What balun, homebrew or commercial, if any, should I use?  I almost
always run 5 watts, all CW.

Re: [Elecraft] Price Increase Alert (Now Feb 8th)

[Eric Swartz - WA6HHQ, Elecraft]

In response to numerous requests from customers this week for a little more 
time to beat the scheduled price changes with their orders, we have moved the 
date for the changes a few days later to this Monday, Feb 8th.

This should give those who missed the original announcement and everyone else 
through this weekend time to to place their orders.  :-)

(See below for details of the original announcement.)

Re: [Elecraft] [P3TXMON] 200W sensor at higher power levels

[Eric Swartz - WA6HHQ, Elecraft]

Its probably OK for short durations at up to about 350W.

If you hit it with 1500w it might survive, but that will cause a couple of low 
power resistors to dissipate up to 35W, so they might be in danger of failing.


Note that the 2000W coupler is good down to 1W and is what I use for all my 
operating, QRO or QRP. The 200W coupler is good down well below a watt, for 
those who like to go even lower..

This is a Good Thing. Home Depot has massive displays of LED bulbs, which

I think everything in our house is now LED except for some candelabra-size
25-W bulbs in the dining room. My wife doesn't like the look of the LED
replacements in this category, but eventually they, too will go. Then our
electricity consumption due to lighting will be down by 84% for the entire

Edison would have been amazed to put his hand on a cool 10-W LED bulb
that's putting our just as much light as a hot 60-W incandescent. Or maybe

just dead. It has hardly been used in the years we have had it.

I have replaced all my CFLs with Halogen clear bulbs (40 watts) which we

can still get through some loophole, at least for now. I care not that they
produce some heat as well as light, as it warms the house up who we have
the lights on in the winter. I am stockpiling them.

I have LEDs in the bathroom that don't appear to cause any noise,

ironically the 12 V halogen ones before did because of the SMPSU that they
used.

I also have a Phillips LED lamp bulb in a table lamp that is totally RF

quiet.

That sounds like the CFL failed as it was designed to fail.

CFLs draw more current as they age. Eventually the power supply is
overwhelmed by the current demand and fails. All the CFLs I've seen use

a

tiny (1/8 or 1/16 watt) resistor as a fuse. Before anything else gets
overloaded enough to fail, the little resistor acts as a fuse and opens.
But, being a resistor, it fails like a resistor often with some smell

and

brief puff of smoke. I suppose it might be possible for a flame as the
covering burns, but that should be inside the base enclosure. I've never
seen anything but a small puff of smoke if I am looking in that

direction

True, and I notice it here when I get beat by other W6s with similar 
stations other than the amp.  I live with it given the incredible

them. They just work.


My hope is that Elecraft becomes a giant corporation with enough R

Re: [Elecraft] KPA500 finals blown

[Eric Swartz - WA6HHQ, Elecraft]

The KPA500 will automatically go into standby if it feels it is getting too hot. 
This is done with a safety margin between that temperature and the max operating 
temp for the PA's.


Its perfectly OK to operate it at the full fan speed. We expect it to go there 
in normal higher duty cycle operation.

Well ... it says that, in any 15 minute interval, you can be key-down

followed by another such sequence.

Is 10 min down/5 min up repeatedly the same as 40 sec down/20 sec up
repeatedly?  Intuitively, it seems to me that the PA-heatsink will come to
some equilibrium temp and a 10m D/5m U duty cycle may not yield the same
final temp as a 60s D/20s U duty cycle.  Then again, I struggled through
Thermodynamics.

I know the original KPA500 field testers were encouraged to run the amp at
"full bars."

Re: [Elecraft] [PX3] - symmetrical reflections about the center point

Hi Kevin,

Try removing each end of the IQ cable between the KX3 and PX3 and firmly

fully inserted in the jack, leaving one of the IQ lines open.

Re: [Elecraft] K3S VFO-A Dial Knob

[Eric Swartz - WA6HHQ, Elecraft]

If you look at the main home page link of the one K5WA posted below, 
http://www.rkrdesignsllc.com/ , near the bottom of the page it states:


RKR Designs LLC no longer sells or services Ten Tec products. For all Ten-Tec 
products, Sales and Service, go to: www.tentec.com


The tentec.com site has a single placeholder page with a statement by the new 
owner and is not taking any product orders at this time.

Re: [Elecraft] K3S VFO-A Dial Knob

[Eric Swartz - WA6HHQ, Elecraft]

Soon, but we're waiting for commitment on delivery for the next increased 
production run of these.  As soon as we have that date and if it looks 
reasonable, we'll put the K3S VFO grip ring on the order form.


Our prime reason for being careful on this is to not sell out all of our current 
stock of the grip ring and then not be able to ship K3Ss.

[Elecraft] Elecraft Website back up today for Verizon FiOS & DSL customers

[Eric Swartz - WA6HHQ, Elecraft]

Wow - this has been frustrating for us (and all of our Verizon based customers!)

Verizon appears to have fixed the routing problem from their FiOS and DSL 
customers to Elecraft.com sometime last night. The fix slowly migrated through 
the net and based on customer feedback received here, most Verizon customers 
were up and able to access elecraft.com by sometime this morning.


It apparently was a problem with misconfiguration by Verizon for their traffic 
via an internet backbone router (layer42.net) upstream of the ISP that hosts 
elecraft.com.  Interestingly when accessing the Elecraft website from other ISPs 
(Comcast etc) it also routed through layer42.net's backbone and router with no 
problems. Our ISP has been in contact with layer42.net, and layer42.net 
confirmed it was a Verizon problem. Unfortunately Verizon was very slow to 
correct the problem, much to our frustration (and our ISPs and Level43.net's).



New Server:
While the Verizon FiOS saga was transpiring this week, we also began 
implementing a backup copy of the elecraft.com webpage on a totally different 
server farm both hosted by a different company and geographically located 
outside of our immediate area. We copied all of the website and ftp files over 
to this new server and had it ready to go this morning. It actually turns out to 
be faster for web access, and also for ftp file downloads of new f/w via our 
utility programs. As a result, we decided to switch over to the new server for 
elecraft.com at about 2000 Z today. Its been up and operating since then. Its 
new iP address may take up to 24 or more to propagate through the internet's 
network of DNS servers, routers and your browser programs.

Re: [Elecraft] Elecraft Website back up today for Verizon FiOS & DSL customers

[Eric Swartz - WA6HHQ, Elecraft]

I hit send too soon.. :-)

Continuing regarding our new server location for the Elecraft web page; both it 
and the prior server are both active with the same data, so you will still see 
the same elecraft.com web pages displayed even if you are still pointing to the 
old iP address for Elecraft.com.


For those of you who can 'ping' elecraft.com, the old server address starts with 
63.249.. and the new server address starts with 50.31..


For Windows users, from the command window you can both ping elecraft.com and 
flush your local DNA cache to forcibly load the new iP mapping for the new 
elecraft.com server. To flush the cache, type "ipconfig /flushdns"   
(without the quotes) and then "ping elecraft.com"  to see if the address 
changes to the new one. This may take more than one try to be successful, 
depending on you DNS configuration. Also, it may be necessary to close your 
browser and then restart it to load flush the browser's local web page cache. 
Its also possible your ISP uses multiple DNS servers that may update at 
different times..


You can tell if you are seeing the web page from the new server by scrolling 
down to the bottom of the elecraft.com home page and looking for the "Last 
Edited" date section, located on the right just above the web page links 
bordered by bars. If you see "Last Edited:  **NEW SERVER**:  , you know you 
are on the new elecraft server. If you don't see this, don't worry, the new 
address will automatically propagate to your local DNS servers over the next day 
or so, and you will still be able to access elecraft.com on the old server in 
the meantime.


One nice impact of this is that we now have a way to immediately switch to the 
backup copy on a totally different server for elecraft.com should there be a 
major problem with the main server. We'll keep both servers active for this reason.


Please let me know via -direct- email if you still can not access elecraft.com 
at all, or if there are any problems with the new elecraft.com web page once 
your DNS updates and you can get to it.


Whew! Have a great weekend everyone.

Re: [Elecraft] K3 - AFSK anamoly? No replies, try again

[Eric Swartz - WA6HHQ, Elecraft]

This sounds like a crystal filter offset setting is incorrect. (Also check to 
make sure your IF shift setting on the front panel is not set to an extreme.)


Check the setup menu entry for each crystal filter and its offset setting. 8 
pole filters should be set to a zero offset. 5 pole filters should be set equal 
to the + or -  number marked on the filter or the label stuck inside the radio 
(typically on the top cover.)


Setup of the filters is described in the K3 manual. (I believe the assembly 
manual, but it may be in the operating manual.)

Lets end this thread now and take it to direct email between posters, if needed, 
as we're flooding the list with a huge number of single topic postings. Its 
certainly exceeding the near term topic posting limit.


Please remember that this is the Elecraft list and that most posts shuld pertain 
directly to Elecraft product topics. Other more general ham radio postings are 
certainly allowed, but please limit those postings and replies to a much smaller 
total - typically 5-10.

Re: [Elecraft] Elecraft website now accessable through FIOS in NY

[Eric Swartz - WA6HHQ, Elecraft]

It appears its not a DNS problem, but is is specific to Verizon and how it 
transfers web page data from our web site.


We've been able to reproduce it through remote access to several of our 
customer's (who use verizon) PCs. It appears to be related to page size and 
possible proxy MTU settings at Verizon.



Brandon here at HQ created created a test page. (Its a small blank page.)

http://www.elecraft.com/blank.html

This page will help test MTU incompatible settings between network providers.
The file size of the blank page is small enough to pass most MTU settings in one 
single packet.
We suspect the Verizon FIOS users will be able to load the blank page, but not 
regular www.elecraft.com pages.


We suggest users load the blank page, and then try to load our www.elecraft.com 
homepage.
They should send the results to Verizon for further inspection of their internal 
network.


As far as we can tell, the web server is working just fine.  All other ISPs do 
not appear to have the loading issue.
This appears to be Verizon FIOS and DSL specific as the regular Elecraft web 
page loads OK through Verizon 4G here.

Re: [Elecraft] Elecraft website now accessable through FIOS in NY

[Eric Swartz - WA6HHQ, Elecraft]

Hi Knut,

Its not anything we're doing here that is non-standard, and nothing has changed 
in that regard in the last week or two.


It appears Verizon made some sort of change to their system and it is causing 
these problems. Fortunately, it appears that the original poster and several 
others who reported problems are now getting the Elecraft web site OK. If 
Verizon is addressing this, it may take 24-28 hours to ripple through their system

Hi again Eric,

With that said, if the problem is really your web site pushing the MTU

having problems) faster by working with your web site host to reduce this.
Verizon is not known to be a fast working machine. But we can still have
some patience.

Hi Eric,

Brandon's test (blank) page loads with no problem. elecraft.com http page
does not. Verizon should be aware of the problem by now and hopefully
working on it.

Re: [Elecraft] Fios and Elecraft Website Access

[Eric Swartz - WA6HHQ, Elecraft]

We've checked here and nothing appears wrong with the actual server for the 
Elecraft web site. We've checked it here via multiple providers (ATT, Verizon 4G 
cellular, ATT optical). All those appear to access it OK.


It appears the problem resides at Verizon (and possibly others) with their 
network DNS servers. There -was- a short optical fiber outage mid-last week 
upstream of the ISP that hosts our Elecraft website. Its possible that the 
network re-routing required when this was fixed was not properly updated by 
Verizon on their servers and possibly other network routing servers.


Also note- you can access our web page via two addresses:
www.elecraft.comand
elecraft.com
Both end up at the same place.

One additional thought:
If you are still having problems, you may need to flush the local DNS cache of 
old internet routing records on your PC. This can be done easily via the command 
window in Windows.


From the program menu (icon on the lower left corner of the windows screen) 
chose 'run' and then enter 'command' as the program to run and press enter. This 
will bring up a dos command window.


From the command prompt in that window type:   ipconfig /flushdns
Then press the enter key.
Then type: exit   followed by the enter key to close the window.

Lastly, close and re-load your browser and reload the page.

Please let us know if either of the elecraft webpage addresses above still fail 
to work.

[Elecraft] KIO3B Upgrade now on our Order Page

[Eric Swartz - WA6HHQ, Elecraft]

We are now ready to take orders for the KIO3B upgrade kit for the K3. This 
upgrade Includes: KIO3B 3 board set (KIO3B main, digital and audio boards), 
RJ45-RS232 cable, USB cable, h/w and manual.


Its can be found on our order form at:
http://www.elecraft.com/elecraft_prod_list.htm#kio3bupkt

(There is also a link to it on our order page table of contents.)

See our KIO3B Upgrade FAQ for details:
http://www.elecraft.com/manual/KIO3BUPGD-FAQ%20rev%20A.pdf
===

The new KIO3B (standard on the K3S) adds high performance USB sound and comm 
port capabilities to the K3, eliminating the need for RS232 and 3.5mm analog 
audio cables to the PC.  Basically one USB cable to the PC (included with the 
KIO3B) handles this all, eliminating both RS-232 headaches and potential RFI 
issues with analog audio paths.


The KIO3B also includes all of the analog and digital capabilities of the prior 
KIO3 (Line in/out, headphone, mic, Aux Conn. and RS-232).


If you are using an existing P3 with the upgraded K3 and KIO3B, you will also 
need to purchase the CBLP3Y, which provides a path to the P3's RS-232 connectors 
from the RJ45 jack on the KIO3B, and supports one USB cable connection between 
your PC and the K3 for all comm port I/O and audio.  (New P3s are shipped with 
this cable.)


The KIO3B still also supports all of the old methods for rs-232 connections 
between the K3, Computer and P3, so you can just drop it in to your current hook 
up without using the USB comm port, if desired.


The KIO3B Upgrade FAQ linked above has diagrams showing these two main ways of 
connecting the KIO3B to the P3 and computer.

Eric

Re: [Elecraft] KIO3B pricing (was: Re: K3IOB)

[Eric Swartz - WA6HHQ, Elecraft]

Hi Olli,

Yes, 389.95 is the correct price. 

This is not a single board. It is a three board set that costs much more than 
our old KIO3B to manufacture.  The board set also now contains a new USB Codec, 
USB Comm port, Internal USB hub and additional logic to handle routing of data 
between the USB and RS-232 paths (all fitting into the same space as the old 
boards). The upgrade kit also includes two external cables (one custom), new hw 
etc.  These boards are also manufactured at a much lower volume than those in 
the PC market, with the subsequent increased cost on our end. A $200 price 
would be selling at a significant loss.

Our goal is always to price our products as reasonably as possible after taking 
into account our production and support costs while making enough profit to 
continue to exist and serve the amateur radio market. We walk that line 
carefully every day. And its always a challenge! :-)

Re: [Elecraft] KIO3B pricing (was: Re: K3IOB)

[Eric Swartz - WA6HHQ, Elecraft]

Also note that the KIO3B has all of the original KIO3 analog and digital 
functionality and HW. Adding the usb sound and USB data hw to that did not 
increase the end price by over $200.

Lastly at ham radio market volumes, which are much lower than most consumer 
products, the cost to develop and support any design is folded in the price we 
must charge over time. We can't survive any other way.

We were able to accelerate expected date to open orders to begin the middle of

Re: [Elecraft] KIO3B

[Eric Swartz - WA6HHQ, Elecraft]

Hi Bill (and everyone else interested in the KIO3B upgrade),

Unfortunately pulling the KIO3B boards out of a packaged K3S kit or already 
built K3S is not practical, and would really cause production problems here. We 
build the assembled K3S base units ahead of time before option configuration, 
and for kits, the KIO3B boards are inside of sealed boxes of kitted product 
packaged ahead of time.


We are also fully maxed out getting December orders out the door for last minute 
shoppers, presents etc.


Fortunately, we will begin taking orders for the KIO3B board set the week after 
next - after the holiday rush. This will probably on either the 29th or 30th, 
and we expect to begin shipments 5-10 days after that. We should have the extra 
KIO3B boards in-house and tested by then.


Please do not try to order or call before we announce that the order form is up 
as we do not have the web order form or internal order systems ready to handle 
KIO3B upgrade orders. (We prefer on-line orders to avoid phone overload here..) 
We are also maxed handling the holiday order rush.


We will post here on the Elecraft List and of course on our web page as soon as 
we are ready to take orders and the order form is up and running.


We're running as fast as we can - Its a busy month at Elecraft this time of 
year.

Re: [Elecraft] K3S RS232 "Y" Connector causing port conflict

[Eric Swartz - WA6HHQ, Elecraft]

If you need to block the TX lines from the amp to the K3 (or from the amp to the 
P3's computer connection if that is also in the system) making a custom cable or 
taking a M-F 9 pin adapter with the proper pins broken off can make it easy.)


The key thing to remember with RS-232 is that while you can usually have 
multiple devices listening to a path, only one can transmit.

So far we know that you have tried using some Y-splitter on the RS-232 line. 
It didn't work, and Don provided a clear and detailed explanation why that was 
the case.


Serial data is echoed bidirectionally through the OM2500A. There is no "listen

Hi Charles,

When the K3S is using the USB comm port for talking bi-directionally  to the

Amplifiers, Steppir antenna controllers etc to listen to for band and frequency

communicate to the amplifier through the RS232 Port at the same time. As
I understand it, you can use the RS232 port, or the USB port, but not
both.

Thanks everyone.

[Eric Swartz - WA6HHQ, Elecraft]

One other note - I see you posted to Elecraft and topband reflectors on your 
post. Please do not cross post when posting to the Elecraft list as that in-turn 
causes a flood of email to the other list and back to here, including bounce 
messages from non-members that fill our admin emaibox.

Hello all..This AM on 160 meters there was a station CQing on 1.820.6 with

but perfectly Q5  on 1.830.6.  I turned the noise blanker off and of course the

with my radio after a recent factory alignment?   I have had a K3 for years and 
never noticed anything like that before but then again this AM was very quiet

Re: [Elecraft] P3 question - few signals show on the waterfall

[Eric Swartz - WA6HHQ, Elecraft]

Have you tried adjusting the REF Level? This is a per band base level for the 
display that directly impacts the minimum signal level displayed.


There also is a SVGA Menu item called 'Bias' that adjusts the sensitivity on the 
SVGA waterfall to compensate for different monitors etc.

I've gone over the Elecraft documentation and Fred Cady's booklet on the P3 
and I do not see any sensitivity adjustment for the display.   There is the 
level calibrate but if I move that to extremes, it throws off the K3 and P3 
showing the same signal strength.  I don't think that is the right adjustment 
for what I want.

[Elecraft] List Manners, etc.

[Eric Swartz - WA6HHQ, Elecraft]

Its come to our attention that some list members have sent **private** emails 
chastising or criticizing others who may have made a comment or posted a 
question to the list. This is in direct violation of our "keep it friendly" list 
policy.


A note to aspiring list police: Please restrain the urge to
email someone or the list admonishing them about a posting. The last
thing we want to do is to scare anyone off the list. As the 'official'
list Cop, I'll jump in as necessary to keep everything orderly. I do
this off line and occasionally to the list when it is appropriate. Our
goal is to keep the Elecraft list a fun, informative central clearing
house for Elecraft and Ham Radio related information and enthusiasm.

All questions are welcome, and it is in direct violation to
personally criticize a poster for making a post with abusive emails. (Even if 
the information they seek is basic, is on our web page or is available via the 
list archives, its OK to ask about it.)


Anyone receiving private emails (via the list or direct email) belittling or 
chastising them regarding a post should **forward** that post to me as list 
manager. List members who violate this guideline by abusing others risk 
permanently being removed from the email list.


It is also not necessary to defend Elecraft and to personally criticize a poster 
who has a critique or problem with our radios. (We have pretty thick skins ;-) 
We want to hear critical input so we can continue to improve our products and 
make them the best possible. Its certainly OK correct posters if their 
information is incorrect, and to help them with questions or misunderstandings, 
but please do it politely and with respect.


Overall, the primary  list guideline is to keep all discussions cordial and 
polite on the list and on follow up private emails related to list discussions. 
There is no place for belittling or chastising of list members when you do not 
think they should have asked a question or made a post, or if you disagree with 
their point. Its OK to have polite disagreements and discussions, but not to 
make it personal.


All questions are welcome. Period.

The bottom line:
If you have a question - POST IT.
If you are having fun -  POST IT.
If you are having problems - POST IT.
If you have a suggestion -   POST it.

If you have a complaint about the list or another poster - do not post it to the 
list. Please send it to me. We'll jump on it right away.

[Elecraft] Elecraft email List Official Guidelines 2015 - Updated

[Eric Swartz - WA6HHQ, Elecraft]

Elecraft eMail LIST GUIDELINES 2015-16

For those of you who are new to the list, (and for those of us who have rapidly 
failing memories) here is a quick list of things to remember when posting to 
this list. Please save this for future reference.


The most important thing to remember is that this is a hobby - Let's have fun!

The PRIMARY purposes of this list are to provide a polite and enjoyable forum 
for discussing Elecraft products, share mods, new ideas, feedback to Elecraft, 
share experiences using our products, troubleshooting ideas etc.


The Elecraft email list server (reflector) is provided to further the discussion 
of Elecraft products and related items. It serves as a forum for the discussion 
of both technical and operating topics including product features, construction 
and debug problems, sharing your enthusiasm and impressions from using our 
products and more general ham radio related topics of interest to our customers.


(Please -strongly- resist the urge to reply to an OT topic once it has gone to 5 
posts. Once it hits ten posts do not reply at all (go off list if you feel the 
urge to continue.) Also, please do not try to always get the 'last word'..



1. YOU MUST BE SUBSCRIBED to the [Elecraft] list TO POST to it. (This is done to 
stop advertising spammers from hitting the list.) Any postings sent to 
elecraft@mailman.qth.net by addresses different from the exact ones it shows as 
subscribers will be rejected.


This includes alias (forwarded) addresses like w1...@arrl.net. If you use an 
alias to subscribe you must have it as your from: and return address too. 
Subscribing with w...@arrl.net from your physical address of j...@aol.com will 
allow you to receive postings, but your postings to
the list will be rejected if their from: and reply to: address does not match 
your subscribe address..


Go to http://mailman.qth.net/mailman/listinfo/elecraft to subscribe and to 
change your list preferences. To unsubscribe or to change your list preferences 
(digest, no mail on/off etc.), scroll to the bottom of the page and log in with 
your subscribed email address and the password that was sent to you by email 
when you subscribed (and sent to you each month).



2. If you want to provide an attachment, .JPG picture or other large file for 
use on the list, first post it to your personal web page and then post a link to 
its address in an email to the list. The list strips all attachments to prevent 
viruses from propagating and to keep the archives at a reasonable size.



3. Top posting is the official standard for this list, and its especially
important for those of us who also read our email on smartphones, iPads etc. 
Scrolling though a long thread before getting to the reply text is difficult on 
these devices and costs everyone a lot of time.


Reading the response first, at the top, is a huge time saver, especially when 
you have to read hundreds of emails daily as we do here. We really appreciate 
your adherence to this.


Please also delete -all- footers and as much of the prior email text as possible 
when replying to cut down on overall email size. Please keep the amount of 
copied text from previous posts to an -ABSOLUTE MINIMUM- in your replies.



4. EMAIL OVERLOAD:
If you are overloaded by the volume of individual messages on the list, You can 
view the daily Elecraft list messages for each month in web format at: 
http://www.elecraft.com/elist.html . These archives are updated hourly and list 
postings by subject. (the Nabble archive looks very useful.) Just click on the 
ones you are interested in to read.


You can also set your Elecraft list email preferences to 'no mail' delivery, 
which still allows you to post to the list when reading via the digest.


You can also change your subscription to the DIGEST version, which sends you a 
single compilation each day.


To change your email list options or to subscribe / unsubscribe, go to:
http://mailman.qth.net/mailman/listinfo/elecraft Scroll to the bottom of the 
page to log into your preferences page and set your mail options to 'no mail'.



4a. Please make an effort to keep list volume under control by resisting the 
urge to post a comment on every long discussion thread (CW, Soldering etc.) With 
thousands of list subscribers volume can quickly get out of control if everyone 
feels the need to comment. While we do not overly restrict the subject matter on 
this list, please remember that its primary focus is on Elecraft products, and 
their use. Many people rely on it for pointers on building, using and 
troubleshooting their rigs. Other ham Radio topics are OK, but please keep the 
posts on non-Elecraft topics under control.


4b. *** When emailing about a specific rig or option, please add the rig/option 
name(s) to the first part of your email subject line. (K1, K2, K3, KX1 etc.) 
This will be a huge help for those experiencing email overload and will allow 
automatic filtering based on subject line.

Re: [Elecraft] [Bulk] Re Elecraft] Crackling in Headphones

[Eric Swartz - WA6HHQ, Elecraft]

We have not seen any problem with the synth like this, and we are not 
experiencing it on our current K3S's or upgraded synth K3 radios, or on our 
personal K3s and K3S's,  those in the lab here or those in for repair.


My suspicion is that there is an intermittent elsewhere in the radio of the 
original reporter's K3 (cold solder joint, loose connector etc), and it is not a 
problem with the Synth.


We'll certainly try to reproduce it here, but so far no luck.

There should be explicit links on the manual download page of Elecraft's

turn up reference to the manual.  That just does not make good sense.

Re: [Elecraft] K3S USB RS232 P3 Conundrum

[Eric Swartz - WA6HHQ, Elecraft]

RS232 DB9 "Y" off of the computer side of the P3. Make sure you are only 
listening and not hooked up to send data to the P3/K3 via this path.


We basically take the USB comm data between the K3 and the computer and then 
echo it out the RJ45 CBLP3Y connector to the computer input DB9 on the P3. The 
other connector on that cable returns the P3 data to the K3, along with the 
computer data.

the logging program is what talks to the Acom. I have not figured out the

Re: [Elecraft] K3 NB problem

[Eric Swartz - WA6HHQ, Elecraft]

Hi Larry,

For the IF NB I usually use a level of 3, or 4 max, with a narrow typically for 
the width. This generally works quite well for me with minimal intermod. More 
aggressive thresholds and wider widths significantly increase the likelihood of 
nearby strong signal intermod with IF based NBs.


As another poster mentioned, the DSP NB can be cascaded after the IF NB, or just 
on its own. So trying different combinations of these may also help in your 
situation.

One could do that, of course, but your original post brought ground 
conductivity into the computation, which is, IMO, entirely appropriate.


FWIW, I've done some extensive modeling studies of horizontal and vertical 
antennas at various mounting heights; horizontal antennas don't care much 
about soil but care a lot about height; vertical antennas care a bit about 
height and a lot about soil. That work is on my website.


I think I would use average gain of the antenna as installed as the basis for 
compliance with the Rules, but the question remains, what height for the 
dipole? :)


This is, for me, purely academic. My soil being terrible, a vertical is a poor 
choice for 60M, and I have a bunch of high horizontal dipoles, so I'd use one 
of them. :)


BTW -- there's a 2-part piece on this topic by Rudy Severns in QEX this past 
summer, specifically addressing very short verticals for the 630m band.

Re: [Elecraft] KPA500 troubles

[Eric Swartz - WA6HHQ, Elecraft]

Hi Jack,

I apologize for any consternation this has caused you. 

Since multiple components burned through the LPF  PC board, that is major 
damage and would require replacement of the whole LPF board, which is a major 
cost component of the amp. (Taking out this board and replacing it requires 
disassembly and reassembly of a major portion off the amp.)  The repair cost 
also includes the tech time to diagnose, disassemble, repair, reassemble, 
retest and do full production TX burn-in of the amp on all bands.

Component failure like this can occur in any manufacturer's radio or amplifier 
for many reasons, such as power line surges, nearby lightning strikes, 
operating with excessive SWR, transmitting into a wrong antenna etc. You do not 
need to be operating on a particular band, or even have the amp or radio on to 
incur lightning damage. This can also cause partial damage to components that 
then shows up as a failure later after additional operation. 

As a side note, every year during lightning season we see a significant 
increase in all sorts of 'interesting' repairs sent in to us on all of our 
products. Many times the user is not even aware that a strike occurred 
somewhere nearby while they still had their antennas connected.

I'll review your repair report with our techs to make sure we didn't over 
charge for anything. I'll also check to see if they mis-identified which band 
the destroyed LPF components were from.

Eric

It seems to me that “drowning in Kool Aid” is no worse than what are little

much to do with how many Tera-hertz the DSP chips run or how much the radio 
weighs.

On another list, at another time, for a for a very good radio made by another 
American manufacturer, we had all the same never ending arguments.  I’m sure if 
we took those posts and changed the name of the radio, you couldn't tell them 
from the current crop.   Someone always thought their IC-xxx or TS- was 
so much better.  Anyone saying anything positive about the radio in 
question (on just about any topic) was immediately accused of being a fan of 
Kool Aid and having gone to the dark side.  It took actual measurements of 
(S+N)/N to make the point that — oh, by the way — NR on that radio did what it 
was supposed to do — raise (S+N)/N on the signal of interest — quite well, 
regardless of how much or how little it sounded your favorite “other” radio.

Perhaps someone would like to offer up one or more actual facts,  or make some 
actual confirmable measurements.  It isn’t that hard to do.

not compress.  Soldering "might" have helped, but I went to bananna plugs with 
screw compression wire connections I can re-tighten as needed...

While many people recommend soldering crimped connectors, such as Anderson 
Power Poles, it is not a very good idea.  The reason(s) it is neither 
required, nor desired, is partially as follows:


1. A PROPERLY crimped connection creates a molecular bond between the 
conductor and the connector that is more conductive than soldering.
2. The soldering process causes corrosion because even rosin core solder is 
slightly acidic.
3. The solder that flows into or onto the conductor (wire) causes it to 
stiffen and increases the probability that vibration or movement will cause 
the wire to break at that point.
4. The annealing of the copper wire is altered which also increases the 
possibility of wire breakage due to vibration or movement.


It is absolutely necessary that the proper tool be used for the connection 
being crimped.  If you are going to use a crimped connection it is imperative 
that you have a tool that matches the connector.  If you do not have the 
proper tool then DO NOT use crimped connections.

Folks - let's wrap this thread this morning in the interest of reducing list 
email overload - we're hitting the single topic limit.

Re: [Elecraft] TX ESSB for K3 and CM500 headset mic

[Eric Swartz - WA6HHQ, Elecraft]

Guys - I'm going to close this thread -immediately- as arguing pro-con on ESSB 
is outside of our list guidelines.


There are plenty of other venues to do that.  Let's keep it primarily Elecraft 
focused here with a smattering of other non-controversial ham radio topics ;-)

Bill,

The idea of using ESSB in a contesting situation is bizarre.  Why?

IMO, ESSB has no place on our (usually) crowded bands, and especially not
in a contest.

Frank,

Actually No.

You can build solid state 125Wpep HF amplifiers with TX IMD figures better
than  -42dBc that operate quite happily at full power with only 11V.
Unfortunately they are typically designed and built by Military and
Commercial HF manufacturers
