No worries, thanks a lot Dale. 

I've put down the soldering iron and solder wick and will wait a while. 

Cheers and 73dave / VE7SGI.

Hi Dave, 
I am not where my notes are, but Don's are available... Or I can get back with 
the answers in the morning 
But I know you don't need to trim the led display. Since the switches are 
spaced right... I'll get with you by 7 or so. Sorry it's not right off the top 
for me. 
Have a great day,

Hi Dale, thanks for the answer. 

Yes, I was very careful to make sure all of the switches were soldered with the 
spacer underneath them. 

The front panel board "rocks" on what appears to be the led bargraph. 

I checked the height of the bargraph and it's about 1.5 mm higher than the LCD 
freq. display. 

My choices seem to be A) cut down the feet on the led bargraph so it site lower 
- even with the LCD display -or- B) space up the while board to fit the led 
bargraph - which will make the buttong flush with the front surface. 

Hm. 

Thanks, cheers and 73dave / VE7SGI

Hi Dave, did the switches on the left side get spaced off the board using the

Hi all. 

I finally broke down after a few years of K2 envy and ordered a K2/10 with SSB, 
NB and 160M. 

I'm part way through building SN 7438 and have run into a problem. 

I'm trying to fit the front panel board to the front plate and am having a fit 
problem. 

There are 3 short round spacers that set the clearance between the front panel 
pcb and the metal front face. 

When I insert the front panel pcb into the faceplate, the left side ( side with 
the LED bargaph ) sits too high. 

This causes the spacer to sit up off the face and the buttons to sit flush with 
the face. 

The other side fits fine, the buttons protrude partially through their holes 
and the spacer bottoms out on the face. 

I investigated the problem and it appears to be the led bargraph which is too 
high. 

The led bargraph has 4 little tiny feet which space it off the pbc, I have 
seated the led tight to the pcb with the feet touching. 

Before I unsolder the led bargraph ( groan ) and cut off the feet ( which the 
manual said to leave on ) does anyone see somethign I'm missing - please ? 

Thanks a lot for the bandwidth... 

Cheers and 73dave / VE7SGI.

[Elecraft] Elecraft CW Announcement

[kevinr]

Good Evening,
   Weather has been quite nice this week unlike the propagation. But 
the weather is getting worse so maybe propagation will improve.  Without 
the sun calling me outside it would be nice to be able to get on the air 
reliably.  I don't think there is an inverse relationship but one can hope.


   Please join us tomorrow afternoon and evening.

1) Hail signs  (first letter or two of the suffix of your call)
2) NCS help  (as well as QSP/QNP  help)

Sunday 2200z (Sunday 3 PM PDT) 14050 kHz
Monday 0100z (Sunday 6 PM PDT)  7045 kHz

   Stay warm,
  Kevin.  KD5ONS

Re: [Elecraft] [K3] Power control sensitivity with KPA500

[Fred Jensen]

H ... strange.

Mine isn't at all sensitive and once set, I never really touch it.  One 
thing ... like most Elecraft rigs, the instantaneous power out of the K3 
will adjust on the first couple of dots or dashes [or syllables] to a 
new setting.  If I change the K3 drive setting, even by one watt, the 
KPA500 usually hits 700W on the first dot or dash.  After that, it 
settles back immediately.  The amp is a bit conservatively designed :-), 
I've run mine on RTTY at 550W for a whole contest.  I think it's just 
the internal ALC working.


One thing I would like is instead of the K3 telling me the amp is in 
standby or operate, it tells me the power the K3 is going to deliver 
when I first tap the key after changing the amp status.  The per-band 
tune function has not worked for me on very rare occasions.  I'm sure 
it's pilot error, just don't know what I've done when it happens.

me to add 50W of KPA500 output when I really want, say, 10w or 20W, but
maybe I'm being too finicky.

I normally use the per-band tune menu option so it's only a problem when
adjusting the drive, of course.

I'd appreciate having a K3 menu item to adjust the sensitivity of the power
control.

Re: [Elecraft] [K3] Power control sensitivity with KPA500

[Don Wilhelm]

Jim,

If you want more precise power control at levels below 100 watts, why 
not put the KPA500 into standby?
The KPA500 has approximately 15 dB of gain, so the resolution in power 
output is 15 dB (31.62 times) worse than the power resolution on the 100 
watt K3.


With the KPA500 in standby, the sensitivity of the power knob will be 
31.62 times better than with the KPA500 active.

Re: [Elecraft] P3 -- Span slow to update

[tomb18]

Hi
I noticed the same behaviour recently as we'll.
In addition, it appears that sometimes the p3 will not issue a qsy either
from the hardware or via software either.
It seems to happen when there is a fair bit of rs232 activity to the k3.
Ill look at this in more detail in the next couple of days since I happen to
be in the middle of optimizing the communications Tito the k3 in some
software I'm writing.
Tom

[Elecraft] K6DGW QRPTTF

[Fred Jensen]

What a super day!! This was a joint expedition with Rich, NU6T, who
operated his KX3 on SSB on 20 and 15.

K6DGW QRP CW 20m Bald Mtn W6/SN-047 4 pts [4,613 ft]

QSO: 21 x
SPC: (10 +
Summits: 8)

378
x3=1,134 final score [we were on a registered SOTA summit worth a 3x
multiplier]

K2+AlexLoop
4Ah 4S1P LiFePO4 battery

WX: Fantastic! Mid 70's in shade, warmer in sun, light breeze, clear.
Quite a bit of pine pollen. :-( Almost worked a JA, couldn't quite
complete. Great breakfast in Georgetown, late lunch/early dinner in
Cool [that's the name of a little town not far from here. Metropolitan
Greenwood is about half way between Cool and Georgetown. Bumper sticker
there: "GREENWOOD -- Beyond Cool!"]

The Sierra foothills are laced with a variety of historic trails [and
gold mines], probably the most famous is the Western States Trail which
originally ran from Salt Lake City to Sacramento. It's across the
Middle Fork of the American River from Bald Mtn so we don't claim "close
to a trail," not that it would have changed the score. I live 1/4 mile
from the original transcontinental railroad [now Union Pacific], and a
mile from the Lincoln Highway/US40, so "Happy Trails" was a really great
theme!

Really fun time, great to get outside for some "Field Therapy" as Rich
puts it. Thanks to the organizers, about as perfect a radio day in the
field as it could get

Gerd,

You did not say which microphone you are using.  An electret microphone 
needs bias turned on, dynamic microphones do not.

Did it work before?  If so, what settings may have been changed.

Do not overlook the microphone itself.  Does it work on another 
transceiver?  Does another microphone work on the K3?
If you have a variety of microphones, *most* Kenwood microphones are 
dynamic type and will work with the K3 (bias off).  Elecraft microphones 
need bias turned on.  Other microphones may or may not have the correct 
mic plug pinout to work with the K3.
Heil microphones are a mix of dynamic and electret types, and must have 
a Kenwood adapter to work with the K3 (all Heil microphones are not the 
same, one must specify the complete model/type).

Re: [Elecraft] K3 PA temp acting up

[Buck k4ia]

Don - thanks

If I let it sit while turned on, the fan will bring the temp down, then 
I can turn the power back up and operate at 100w.  The fans keep the PA 
temp around 45C.  So I don't think the finals have gone - yet.


It is drawing about 2 amps with the power turned off but plugged in and 
a little under 4 amps in receive when turned on.


I was biased toward the bias but don't understand why it is drawing 2 
amps of current while turned off.


I have not installed the gold connector mod yet.  KPA3CONMDKT  Any 
chance the problem is there?

If you have the same problem with everything unplugged, an email to

If I turn off the power, the finals still heat up and when I turn the

Any ideas?

Re: [Elecraft] No mikegain

[Don Wilhelm]

Gerd,

You did not say which microphone you are using.  An electret microphone 
needs bias turned on, dynamic microphones do not.

Did it work before?  If so, what settings may have been changed.

Do not overlook the microphone itself.  Does it work on another 
transceiver?  Does another microphone work on the K3?
If you have a variety of microphones, *most* Kenwood microphones are 
dynamic type and will work with the K3 (bias off).  Elecraft microphones 
need bias turned on.  Other microphones may or may not have the correct 
mic plug pinout to work with the K3.
Heil microphones are a mix of dynamic and electret types, and must have 
a Kenwood adapter to work with the K3 (all Heil microphones are not the 
same, one must specify the complete model/type).

Re: [Elecraft] help requested

[Don Wilhelm]

Luc,

I really cannot tell whether you have a K3 problem or an antenna problem 
with the information you have provided.
If you have access to a signal generator with a 50 uV output (Elecraft 
XG1, XG2 or XG3 will do nicely), first connect it to the normal antenna 
jack - you should see S-9 if your S-meter is properly calibrated.  If it 
is not S-9 you can calibrate the S-meter or somply note the deflection.


Next, put the signal generator on the RX ANT (turn RX ANT on) and you 
should have the same S-meter deflection.


If the S-meter readings are substantially different, you have a K3 
problem, but if the signal generator provides the same S-meter reading, 
you have an antenna problem to solve.

Re: [Elecraft] K3 S-meter Reading with ATT on and PRE off

[Don Wilhelm]

Jay,

Normally, the preamp and attenuator will change the S-meter reading.  If 
you do not want that to happen, go into the menu and change to SMTR 
ABS.  I suggest (contrary to the manual suggestion) that you calibrate 
the S-meter with the preamp and attenuator both off before setting SMTR 
ABS, but the choice is yours.  If you calibrate with the preamp on, then 
switch to SMTR ABS, a 50 uV signal will read S-7 rather than S-9.

Re: [Elecraft] K2 Resistance Checks

[Don Wilhelm]

Tom,

You will have to begin lifting resistors and inductors if you cannot 
find a solder bridge by inspection.  If you end up doing that, do it in 
an orderly fashion and keep notes as you work - in the heat of 
troubleshooting often the thought comes up which says "did I try that 
already?" - notes will help with that question.


As Mike K8CN indicated, take a look at 
http://elecraft.365791.n2.nabble.com/K2-RF-Board-resistance-check-failure-U6-Pin-8-tt7559095.html#a7559102 
and see if you can locate the fault using that procedure.


It is very unlikely that you have a bad component, but you should verify 
the value of all resistors that are connected to the 8A and 8B voltage 
rails.

Re: [Elecraft] K3 PA temp acting up

[Tom H Childers]

Howdy Buck,

The first thing that comes to mind is that a strait key has something
on top of it, but I sure you checked that.  Is it possible that there
is a short in a keying circuit or maybe a foot switch that has
something on it or is shorted out while the rig is set in the CW
mode?

I don't think having either situation could cause transmit unless the
rig is in CW or data mode.

Is the TX LED lit up?

Good luck finding it...

[Elecraft] Win4K3 Suite

[tomb18]

Well, my replacement for Windows for P3 is nearing completion.  I now provide
full control of the Elecraft K3 with a number of unique features.
Fairly comprehensive control of the K3 with hold functions broken out of the
user interface. Point and click access to functions normally requiring BSet
or menu access.

Control of the P3 as before with Windows4P3 functionality.  New: ability to
use a 720p web cam to display the P3 on your screen.
Control of the KPA500 from the same interface.
Inter-operability with Ham Radio Deluxe Logbook and any software that
interfaces to it including DM780.
Remote access mode:  I have figured out how to stream the P3 video, so the
remote access mode will allow control of your K3, KPA500 and P3 from a
remote location.  So far testing shows a 1-2 second delay for the video
updates of the P3.

You can see the software here
 http://va2fsq.com/wp-content/uploads/w4k3suite1.jpg

I am currently just doing some of the final tweaks before the beta test, and
I invite you to contact me off line to join the beta testing.  

Requirements: Windows 7.  XP may work but is not supported.

I expect the beta to be available in 1 -2 weeks.
Thanks fort all the help so far.

Tom, VA2FSQ

Re: [Elecraft] why mix rf connector types within the product line?

[Ron D'Eau Claire]

Ed wrote:

Very few industrial radios use SO-239/PL-259.  Mainly seen on marine radios
(and CB/ham, of course). 

 

Virtually everything I saw on large ships used the "UHF" connectors.
Properly handled, they worked very well in the extreme marine environment
that included not just salt water, blistering sun and extreme cold, but also
corrosive stack gasses from the engines and a variety of other chemical
attacks, depending upon where the antenna was mounted.

Products like the putty-like coax seal kept the connectors free from any
moisture intrusion and looking like new for years. Connectors treated that
way outlasted the best of the coax cable jackets. We pulled them off to
replace the damaged coax, not because a connector had leaked or failed. 

I prefer BNC's simply because they don't come loose easily in normal
installations. I've noticed a number of people here have had my experience
with intermittent operation and discovered that a PL-259 connector wasn't
fully tightened somewhere. A BNC tends to be on properly or not at all. And,
of course, a simple 1/4 turn disconnects them while the PL-259 requires more
fiddling. 

Outdoors, I use either Type N or "UHF" connectors carefully tightened and
taped and add coax seal if they are exposed to the elements.

Hi,

today I have lost the mikegain. The control is set to 30, powerlevel ist 
set to 50. In a controlreceiver nearby I can only hear a "click". When I 
switch "Vox ON" Vox is not working, When I turn the "Mon" Level On then 
there is no Audio comming out of the speaker.


Any idea ?

Re: [Elecraft] why mix rf connector types within the product, line?

[glen worstell]

In my experience, quality BNC connectors properly installed are very 
reliable.


Cheap (e.g. Chinese) BNC connectors are not reliable, and should be avoided.

I have no experience with BNC connectors on large cables such as RG8, 
but I would be concerned about stress.


For example, I highly DO NOT RECOMMEND the 25' or 50' cables with BNC 
connectors on the end that are sold by Buddipole.


I use UHF outside and BNC inside, but am planning to see if I can 
reliably install type N connectors, and if I can I will probably use 
them instead of UHF.

Re: [Elecraft] why mix rf connector types within the product line?

[Edward R Cole]

Concur on some of what Jim Brown said, but have ordered high quality 
cables from vendors that cater to commercial customers vs ham 
vendors.  For repeaters I used RG-223 cable with N-male connectors 
from reputable vendors.  Of course my employer paid.


I make almost all my cables as, I too, trust my own ability to chose 
good quality components and do quality installation.  I did make up 
RG-58 and RG-8/x cables with crimp connectors where they were in 
long-term installation.  For test cables or any that are subject to 
repeated movement my experience is the crimps eventually fail.  I 
still like them for the convenience (in certain circumstances).


At work I mainly used BNC or N connectors.  Also had TNC and mini-UHF 
on certain radios.  Very few industrial radios use 
SO-239/PL-259.  Mainly seen on marine radios (and CB/ham, of 
course).  Aircraft radios use BNC a lot.  TNC and sma are used quite 
a bit will cellular equipment.


At work I had the $500 Times Microwave crimper with multiple dies for 
different connectors.  At home I have a $99 copy that does a fine job 
on RG-58 and RG-8/x (or RG-6).  But I trust compression nut style 
connectors where I want absolute reliability.


I least like PL-259 as they are susceptible to shorting if overheated 
in assembly.  I use a ton of adapters, though one needs to be careful 
with brand as not all are good.  Amphenol PL-259 are what I use.


BNC is appropriate on the KX3 and other portable 
equipment.  Understandable that SO-239 are used for amplifiers, 
etc.  This topic is kind of no issue to me?  If you were dealing with 
50 contact connectors I might agree.

Playing with my new KX3  (#4048) and notice that when NB is on e.g. 10m and

Using 1.41 fw  version.

Is this a normal behaviour?

I think I read about this before but cannot find anything now.

VFO A/B and rit/ofs knob also, produce a 'creaking chair' type of noise when 
tuning across the band.

Was there a discussion on this some time ago and if so a fix?

Not a big deal but still rather not have it.

Re: [Elecraft] 4-pound Field Day, anyone?

[David Cutter]

Perhaps one of the modern Android or Iphones has an application that will 
run psk or other digital modes: that would bring the weight down.  Perhaps 
do the logging as well.  Be good for emergency use, too.


David
G3UNA


Intriguing idea.  In my case it will take the form of a lightweight psk-31 
station.  Our local club does FD every year so I may just use one of their 
antennas or rig a 20m dipole (probably a sloper).  I will break the 4# 
barrier by bringing my old P90 IBM thinkpad that has a psk-31 program and 
this will force me to make up a soundcard I/F for the KX3.  I have a pile 
of 12v 4AH gelcells which will suffice for power.  Our club call is AL7LE 
but there is some talk of using a better callsign of one of the members 
(might be KL7RA).

With the combination of DUAL RX and NR or Autonotch, you may have loss of
audio, see "DSPT" (DSP timeout) or "ERR DSX" (DSP communications error).
Turning the radio off/on will clear any of these conditions. This can happen
when turning the controls on or off, or on exit from an ATU tune, etc.

We're looking into this. Until we release new firmware, please avoid using
these features in combination.

I have thought about this many times since I bought my KX3 and have started

either could be used when the other was off. Is something like this even

Re: [Elecraft] why mix rf connector types within the product line?

[Tim Hague]

As soon as everyone standardises on N types the better, easy to make, splash 
proof, constant impedance, easily available, industry standard, rugged, it's a 
no brainer...

Re: [Elecraft] 4-pound Field Day, anyone?

[Edward R Cole]

Intriguing idea.  In my case it will take the form of a lightweight 
psk-31 station.  Our local club does FD every year so I may just use 
one of their antennas or rig a 20m dipole (probably a sloper).  I 
will break the 4# barrier by bringing my old P90 IBM thinkpad that 
has a psk-31 program and this will force me to make up a soundcard 
I/F for the KX3.  I have a pile of 12v 4AH gelcells which will 
suffice for power.  Our club call is AL7LE but there is some talk of 
using a better callsign of one of the members (might be KL7RA).


Back in 2005 (I think) I set up a FD psk-31 station using my FT-847 
and the same laptop.  It was powered with a 30w solar panel + diehard 
deep-cycle marine battery.  My antenna was a 20m mobile whip.  I was 
set up in 20-minutes while the club usually takes about 2-hours to 
get the first station running.  Club name is the Moosehorn ARC.
