just a quick question for the collective group here. I have built up my KX-2 travel kit. The first week of november I took it with me to a  cabin I leased outside of Gatlinburg, TN for some portable operating when I wasn?t up in the mountains hiking. I took m y Super Antenna MP-1 plus the parts to throw up a full wave loop for 40M. I did throw the loop up, and it out performed the MP-1 by kudo?s.  But it struck me that it might be nice to add a small antenna analyzer to my kit.
I don?t need a big full size MFJ, which I do have. But something small.  Any experience here y?all?  

thanks in advance for your answers

I was introduced to the SARK-110 several years ago and besides being an 
excellent antenna analyzer, it had one feature that nobody else had 
(when I bought the SARK) and that is called a "Time Domain 
Reflectometer".  This allows you to find breaks, impedance bumps and 
other anomalies in cable runs.

During my 20 years in the Army, I was introduced to a hugely expensive 
HP-140A oscilloscope with a TDR plug in.  We used it to find cuts in our 
buried coax where the local people were digging it up for the copper 
(back in 1967).  From that point on, I always wanted a TDR but they were 
way too expensive (even used) for a poor ham to even consider until I 
was introduced to the SARK by a good friend at the "OzarkCon" QRP 
convention.  It paid for itself quickly by finding where a gopher (or 
mole) had chewed mostly through some buried coax I had going to a 
vertical in the back yard.  The SARK's TDR pinpointed the break within a 
foot and it was probably more accurate than that as my measurements when 
following the cable were somewhat sloppy.

It also makes a pretty decent signal generator as well, can be 
calibrated against WWV with not too much effort, but the minimum signal 
you can output is 50 microvolts (S9) so a good external step attenuator 
is needed along with double shielded cables to minimize feedthrough of 
the SARK's output signal.   Oh yes, I did mention, it's an excellent 
antanna analyzer as well and it will do Smith Chart plots and other 
stuff too.  You can control it with a computer via USB too.

No financial interest in the company, just a very happy user.

Having a graph of the entire band is so helpful, The AA series make for 
a single button test...  You adjust, then hit the go button.  You then 
see exactly what happened to your SWR dip.  Did it go too far, not far 
enough, etc.

Others, you have to fuss with knobs to find the dip, then remember the 
last reading...  Seems like a small item, but it is massively helpful 
when tuning up an antenna.  Takes me 20 minutes to tune a 6BTV now.  For 
an example of charts the AA series puts to computers see a short blog 
post I did on tuning up a 6BTV at:

John,

I saw that one on FunkAmateur/Box73, they sell the kit.

What appeals me is the price (155 euro), the simplicity the way it can 
be built, the features, apart form being a nice graphical analyzer it's 
much more like a signal generator from 100 kHz to 100 MHz. It's readable 
in direct sunlight due to it's LCD type (like te one on a K3 even the 
same backlight color) And the power supply: it uses two AA cells.

I have it and I can say: Highly recommended.

72/73

Hi folks!

Just thought I'd post a note and a quick, hopefully easy question. I'm the
proud owner of a KX3/PX3 pair, which I built from kit. This is some
seriously great equipment. I was thinking that I'd LOVE to use the KX3 in
situations where I need a BIT more than 15 watts (various contests or
chasing DX). My 100 watt go-to radio is an IC-746 Pro, but I wanted to take
advantage of the great receiver on the KX3. An amp was surely in  my
future, so I pulled the trigger this morning and purchased the KXPA100 with
internal ATU!! This one's going to be factory-built. I'm REALLY looking
forward to using the full 100w system. Mys radios feed a HexBeam, Gap
Challenger and 80m loop. Can't wait!

Are there any tips, tricks or is there any advice the Elecraft family has
for using and getting the most out of the KXPA 100?

Thanks!

Subject: [Elecraft] K3 PRE function question
Message-ID: <201712011553.vB1FrVio012472@mail42c28.carrierzone.com>

Just my observations on 6m with only the internal PRE on my K3 
(purchased circa 2010):

I noticed a lack of sensitivity on 6m.  I had a ARR P50VDG preamp 
with 22-25 dB of gain which worked better than the internal 
PRE.  That gave me about 12 dB more gain compared with running the 
PRE.  Also lower NF (typ. 0.5 dB).

I then purchased a PR6-10 and that helps considerably over using the 
PRE.  I have used my K3+PR6-10 for copying 6m-eme signals with a 
single yagi (6-element) so that speaks well of the PR6-10.  I use the 
ARR preamp mounted at tower top for eme and it is a little bit better 
(has more gain) on very weak eme signals using JT65.  I use DIGOUT-1 
to control my PR6-10 and use the pass-thru connections for the 
ARR.  That adds nice convenience for using the two preamps.

I have a second smaller 6m yagi which I use the PR6-10, only.  BTW 
this is equal to my KX3 with preamp ON (which says a lot for the KX3).

My opinion is the PR6-10 makes the K3 better on higher bands than the 
internal PRE (which I leave off).  If you are considering getting one 
its a good (if not essential) upgrade for the original K3 on 6m and 
10m.  Yes, you will see a small rise in the noise reading on the 
s-meter (due to more gain), but sensitivity is improved more than 
that (due to lower NF).  I see about S3-4 noise floor on 6m with the 
PR6-10 and S5 with the ARR.  PRE runs maybe S1 (a guess as I haven't 
used it for some time).

This is a pretty simple question regarding the K3 PREamp (not PR6). If I do
not have the PR6 does the PRE on the front panel help with RX on 6m/2m (int
module) or does it merely increase noise?
Thanks

Do you have the KXV3B with the new/improved preamp installed?  I not, you should consider it.

The choice of analyzers is not that simple unless cheap price is the only
factor.

I have four analyzers: Rigexpert 230Pro, FA-VA4, VNWA3 and Mini60.

Rigexpert covers up to 230 MHz and costs about $500. It is the easiest to
use and has the most functionality. Less accurate because it does not have
OLS calibration and is pretty big, but new models (Zoom) have calibration
and are much lighter. Seems rain resistant. Coax testing for short and
length is a blessing. I use it most of the time. 

VNWA3 covers > 1300 MHz and costs about $600 but needs a computer. Often
requires multiple calibrations requiring an hr. Has two port for filters and
beam testing. I use it only when nothing else works. 

FA-VA4 works up to 100 MHz and is very accurate after good calibration
(included 50 Ohm load is not too good). Light but not the smallest. Getting
things done takes many buttons. Not waterproof. Also. soldering is tricky
and I wonder whether bad soldering will show up one time. I use FA-VA4 for
portable measurements where accuracy is important. For instance impedance of
inv L on 160m. Measure impedance, prepare appropriate coil, and no extra
fine tuning needed. Also very useful to measure properties of toroids across
frequency. 

I also have mini60 that works up to 60 MHz, is very small, can be charged
via USB, and interfaces with Android phone, and costs $100. SWR accuracy is
good but X is not. I leave it for travel.

I have one more suggestion. I have a MiniVNA Tiny, expensive at about $600,
but it is a full two port Vector Network Analyzer in a 2.5" X 2.5" X 1" box
connected via USB. It has both a computer app and a phone app to run it. I
have taken it out in the field where I would never consider taking a 75 lb
VNA. I have used it to analyze antennas, filters, transmission lines and to
characterize caps and inductors over frequency.

I have several antenna analyzers. The best value I think is the YouKits 
FG-01 <https://www.vibroplex.com/contents/en-us/p190.html> .  It's price 
is on the lower end of the scale. It's color display and feature set are 
outstanding. I also have the MFJ 223 which is very compact and highly 
functional. These two are particularly good for travel due to their very 
small size.

The Time Domain Reflectometer (TDR) is a hugely important feature, and is now available with other brands, including some of the RigExpert models.

I do a lot of field work with both HF and VHF/UHF.  In my experience most of the problems I have encountered have been traced to cable defects of one kind or another.  The TDR function allows you to quickly and reliably test the integrity of cabling, allowing you to identify the exact location of the defect.

I am partial to the RigExpert models, which have been reliable and accurate, and very easy and intuitive to use.  

My only quarrel with RigExpert is that they do not offer water resistant sealed cases.   These can get damaged in a wet environment.

I was introduced to the SARK-110 several years ago and besides being an excellent antenna analyzer, it had one feature that nobody else had (when I bought the SARK) and that is called a "Time Domain Reflectometer".  This allows you to find breaks, impedance bumps and other anomalies in cable runs.

During my 20 years in the Army, I was introduced to a hugely expensive HP-140A oscilloscope with a TDR plug in.  We used it to find cuts in our buried coax where the local people were digging it up for the copper (back in 1967).  From that point on, I always wanted a TDR but they were way too expensive (even used) for a poor ham to even consider until I was introduced to the SARK by a good friend at the "OzarkCon" QRP convention.  It paid for itself quickly by finding where a gopher (or
mole) had chewed mostly through some buried coax I had going to a vertical in the back yard.  The SARK's TDR pinpointed the break within a foot and it was probably more accurate than that as my measurements when following the cable were somewhat sloppy.

It also makes a pretty decent signal generator as well, can be calibrated against WWV with not too much effort, but the minimum signal you can output is 50 microvolts (S9) so a good external step attenuator is needed along with double shielded cables to minimize feedthrough of 
the SARK's output signal.   Oh yes, I did mention, it's an excellent 
antanna analyzer as well and it will do Smith Chart plots and other stuff too.  You can control it with a computer via USB too.

No financial interest in the company, just a very happy user.

Yes SMALL and PORTABLE is what I am interested in. I never wanted a TDR. Rig experts are fine analyzes but out of the league of what I want which is something to toss in my "go" bag

The RigExpert AA-1400 fits perfectly in a $40 Pelican 1200 case.

I have mine, charger, batteries, etc in a nice Red 1200.

I would post a pic, but you can't on this reflector.

The FG-01 is? good IF the unit has the improved 2nd harmonic suppression.? Some of the earlier ones only had -6 dB down 2nd.? I have two and the first one went back twice to fix it.

I have several antenna analyzers. The best value I think is the YouKits 
FG-01 <https://www.vibroplex.com/contents/en-us/p190.html> .? It's price 
is on the lower end of the scale. It's color display and feature set are 
outstanding. I also have the MFJ 223 which is very compact and highly 
functional. These two are particularly good for travel due to their very 
small size.

On the simple side I recently built Jack Purdum's Arduino controlled unit for about $60 and it works well and does all the normal functions required for a field operation on 10m to 80m.

I sure envy those of you who live in a quiet enough environment to take 
advantage of that much gain. Here in the city the noise level is so high 
even on 6 meters that even the additional gain provided by the built-in 
preamp on the KXV3B module usually only brings the noise level up; weak 
signals are still buried in all the ambient crap. I previously used a 
PR6 on my K3 and don't really see much difference between it and the 
preamp in the Transverter module. I'm looking forward more and more to 
retirement and a move out of the city.

What calibrations are you doing that take an hour?

You can do a master cal with lots of points in 5 minutes.

I use mine in the field all the time using a Win 10 touch screen tablet.? The 
software is phenomenal.? I've been doing network analysis since the days when 
the calibration curve was a grease pencil line on a CRT.? I (my employer) bought 
one of the first HP8510s sold to a non-governmental agency.? It cost IIRC north 
of $200K, was in a 4-foot rack cabinet and probably weighed 500 pounds.? With an 
admittedly reduced frequency range, the VNWA3 is for all practical purposes the 
equal of the '8510 and I can hold it in the palm of my hand!

With a good external frequency standard (I use a Bodnar GPSDO) it makes an 
excellent frequency counter and works as a limited function spectrum analyzer.

One other thing.? On my 160-meter inverted-L antenna I receive a couple of AM 
broadcast stations at -3dBm.? If I limit the lower sweep frequency to 1.7 MHz 
the VNWA3 is unaffected.? I suspect some of these other boxes are not so resilient.

Wes N7WS
Not associated with any of the players who designed or built this thing.? Simply 
a very satisfied customer.

Hi Ronnie

The TDR is a must have.  Once you start sweeping all your feedlines you
will know they are not as good as you might have thought.  :)

Twice I tossed an entire roll of heliax and twice 2 unique runs of RG213.


If anyone has feedlines older than 10 years, you might want to consider the
investment.

This is why about half of our product line is intended for use outdoors, hopefully far from most noise sources. I?m always amazed to see noise drop from S6 to S0 on 20 meters, for example, when I hike up the hill at a park that?s a quarter mile from civilization.

I have had the Comet analyzer for a year. Although a bit pricey for the number of functions, what it does, it does very well and is a very solid, well built, and easy to use device. With that said, I will add a VNA unit to my arsenal of analyzers soon. 

It sure would not hurt my feeling to see what what Elecraft could do in the analyzer department!

Why must every perceived problem be resolved by buying something? All 
Elecraft rigs, including the KX2, have an indicator for SWR that the rig 
sees. Resonance can be clearly seen by moving up and down the band to 
find it.

SWR is NOT an indicator of how well an antenna works, and antennas don't 
necessarily have to be resonant to work well! That depends on how we use 
the fundamentals of how antennas work. Especially when using improvised 
wire antennas with little or no feedline, the only thing that matters 
beyond the fundamental properties of the antenna is whether the rig can 
match it.

I'd be far more likely to drag along more "stuff" with which to rig 
improvised antennas in whatever surroundings I find myself, and to study 
the ARRL Handbook and Antenna Book to understand those fundamentals.

Hi, Ronnie ?

There are a bezillion to choose from ? big, small, graphical, TDR, need a computer or pad,  etc, as others have pointed out.

Another one you might consider is the iP30z (or iP60z) retailed through Buddipole.  They?re a bit pricey compared to some options, but they have the advantage of being small enough to squeeze into virtually any bag or a shirt pocket, lightweight (7 oz) and do everything you need in the field ? SWR, |Z|.  All the advanced features that have been mentioned are good to have now and then, but if you?re looking for small and imminently packable for a hike into a noise free park or a walk to the beach, as I was, it?s a good choice.  Quick, easy, simple ? and you don?t have to pack the manual to figure it out :-)

Yes.? AND, more important, calibrations can be saved for standard 
measurement setups, so when you're always using a previous setup, 
there's no need to recalibrate -- you simply load the previous calibration.

Like Wes, I've been doing swept complex (magnitude and phase) 
measurements since 1982, first in the audio range, later at RF.? I 
bought the VNWA3e about 4 years ago, and have found it to be the 
excellent that Wes describes.? It has an excellent TDR function. Another 
important advantage of this unit over others is that it is self-powered 
from the USB port, so no external power is required.

TDR can be VERY useful when troubleshooting an antenna or feedline 
problem, and the higher the analyzer can sweep, the more fine detail it 
can show. The VNWA can sweep to 1.3 GHz.? Few analyzers the do TDR can 
sweep nearly this high. A wideband TDR sweep can find all the splices 
and many defects in a feedline.

Another use of TDR is that it allows us to measure an antenna at the 
shack end of a feedline, find the electrical length of the feedline with 
the TDR feature, and then using Smith Chart software (free), subtract 
out the feedline to see the Z and SWR at the feedpoint.

Note also that this is a vector NETWORK analyzer. A NETWORK analyzer has 
input and output ports, so that in addition to impedance and TDR, it can 
also measure the response of any system. You can, for example, measure 
the effectiveness of filters, and the coupling between adjacent 
antennas. These plots of bandpass filter response were done with the 
VNWA 3e. Note that you can display several views of the same 
measurement. These display SWR, attenuation, and reflection loss, and 
the markers show values within the passband and on other ham bands.

http://audiosystemsgroup.com/BandpassFilterData.htm

These data were used to generate this report that ran in National 
Contest Journal in 2014.

Yes, and quite versatile in that mode. Inexpensive SDRs also provide 
limited spectrum analyzer functions, and some of them are quite good IF 
the user is careful to prevent overload and knows how to avoid false 
responses from aliasing.

This can be very important -- many analyzers get blown away by AM 
broadcast stations.

Here are links to the mfr, SDRKits. The VNWA is NOT a kit, it is built 
and fully tested. You want the model 3E or 3EC with calibration kit and 
cables.

Not necessarily. Resonance and point of lowest SWR do not always coincide.

I find that Jim's thoughts and findings are similar to mine. SWR is 
really not a good indication of how well an antenna works. One of my 
coax lines has a 1:1 SWR from 160M through 6M.? It doesn't receive well 
nor transmit well.? It' has a dummy load on the distant end.

Along the same line, I have a home brew variable L network consisting of 
a tapped inductor, about 24 taps, and a 500 pf variable capacitor.? I 
find it will match about anything that is hung on one end.? If it 
doesn't match, simply turn it around and most likely a suitable match 
will be found.? In all cases, my random wire is not a resonant antenna 
but a length of wire tossed over a tree limb.?? With this, the SWR 
indication on the radio is all that's needed.

Agreed.?? I've always said hams cut an antenna a bit long and then trim 
it to get the lowest SWR at the desired frequency. This does not 
necessarily make for a resonant antenna.??? My 75M antenna is resonant 
at 3.8 MHz as determined using a Grid Dip Oscillator,? but the impedance 
is about 35 ohms giving a SWR of about 1.4:1 .? At 3.9 MHz the SWR is 
1:1.? The length is actually 123 ft.? But the SWR 1:1 point indicates 
the antenna is 119.8 ft in length.

The resonant electrical length of a 1/2 wave dipole antenna is defined 
as Length being = (492 x K) / Frequency [MHz.]??? This does not assure 
it will have a 1:1 SWR at the design frequency, but only that it will be 
resonant at that frequency.?? {K = ratio of 1/2 wavelength to conductor 
diameter.? Typically for wire HF antennas a value of 0.95 is used.}

Just remember, the radiation resistance of the antenna will vary 
according to height above ground.? Thus a 1/2 wave dipole at resonance 
will have its center feed impedance vary from some 20 ohms at 1/8 
wavelength above ground to over 90 ohms at 3/8 wavelength above ground.? 
And at 1/2 wavelength above ground the impedance is near 70 ohms.? Of 
course ground conductivity will affect the actual results.

Bob and all,

The "classic" formula for a wire half wave dipole (known to most hams) 
is 468/F (length in feet and frequency in MHz), and your "492 x K" 
factor is correct.  Sorry for those who use metric, you will have to 
convert)

However, that may not lead to a resonant antenna due to a number of 
factors - height above ground, proximity to other objects, diameter to 
length ratio of the wire among the most obvious factors.

In his years on this planet, L.B. Cebik long preached that "cutting 
formulas" such as 468/F were only an approximation.

Armed with an antenna analyzer and a calculator plus measuring tape, you 
can cut an antenna to be 'resonate' at the shack end of the antenna 
feedline in two tries.  The following technique appeared in QST 
Technical Correspondence for May 2017 (yes, it was my contribution).

The steps are as follows:
- Cut the antenna according to the 468/F formula and add 10%.  Write 
down the length.
- Put it into its final position and with the antenna analyzer, measure 
its resonance point (take your pick of whether that is point of lowest 
SWR or the point where the reactance goes to zero).
- Multiply the length of the antenna by the frequency you picked to call 
the resonant point.  That will yield a number to replace the "468" in 
the cutting formula.
- Use the resulting number and divide by the frequency where you want 
resonance to be.  That is the new length of the antenna.
- Cut the antenna to the new length and put it up and operate.

This works well for HF.  VHF may have other factors involved, so you may 
have to check the results again after the initial adjustment, but the 
principle remains the same.
This method takes into account the antenna surroundings and shortens the 
"cut and try" process considerably.

Message-ID: <201712020149.vB21nfjp020512@mail40c28.carrierzone.com>

Wayne and all:

A graphic example is my experience when I first arrived in Alaska to 
live in a small town of 75 people at end of 16-mile dead-end gravel 
road surrounded by the Chugach NF.  I rented a one-room cabin 14x16 
foot with a wood stove- that's all.  No electricity, no telephone, no 
running water, no toilet - just an outhouse.  Nearest electric power 
was 3-miles away.  Hooking up my battery operted TS-180S to a 80m 
dipole the s-meter did not budge off zero.  I could hear out to 
800-1000 mile everynight on 80m.  All HF bands were quiet.

Ten years later the electric utility extended lines to my property 
and I had both power and phone service.  Noise went up to 
S3.  Population of the town grew to 150 and the main road was paved.

Now I live about 100 miles west of there in a community of 4,000+ 12 
miles from a small city of 7,500.  80m runs S5 on a quiet day; 6m is 
also S5 noise floor.

So good luck finding that quiet place (beyond civilization)!  I live 
on the Kenai Peninsula of Alaska with area about the same as Ireland 
and pop of 55,000.  Everyone has wireless junk so "there goes the 
neighborhood".

I still can hear the occasional ATV, dirt bike or  snowmachine pass 
by the house.

Next move is the backside of the Moon!  LOL

This is why about half of our product line is intended for use 
outdoors, hopefully far from most noise sources. I?m always amazed to 
see noise drop from S6 to S0 on 20 meters, for example, when I hike 
up the hill at a park that?s a quarter mile from civilization.

If you do it often enough, you can cancel your gym membership :)

I using a KX3/KXPA100 and I'm noticing that when I'm in TX the RF meter on the rig matches the set power of the rig, but on the KXP100 meter, it shows 10 or more watts less output.? Some examples:Rig?? Amp50w? 40w60w? 50w70w? 60w80w? 70w
Here is what i've checked so far.? The Powerwerx PS is showing 13.8v when receiving and dips to 12.9v when in TX, so I don't believe I have a voltage problem.? I've moved the rig's power connection? back and forth from the front of the Powerwerx? PS to the top power pole connection on the back of the KXPA100 with no change.I've also re-tuned all bands from 10-40 meters with my LDG100 remote tuner and the highest SWR I receive is 1.4:1 on 30 and 40 meters.? All of the other bands are 1:1 to 1.2:1, so I don't think I'm getting any power foldback because of high SWR..? Does anyone have any thoughts on what's causing this differential, and if two power output meters are never going to be in sync, which meter is the most accurate?
Also, as an aside. Is there something wrong with the KX3 group from Yahoo? I haven't recieved a digest in days and when I try to get into the group I get an error message
Thanks,Jim W7JHR

I live on a long, thin lot is suburbia. My house, and my 
neighbor's houses are at the street end of our lots leaving lots 
of area behind. I have found that the RF noise in the back part 
of our lot is much lower than in the front part. That's where I 
try to put my antennas.

Dear Peter,
Maybe your mic is picking up the fan noise and transmitting it over the air. Try disconnecting your mic and see what happens.
Sincerely,

My first post, new builder, old man (74 years young!). I've been inactive
for some time but looking forward to getting back on CW with the new K3S,
P3 kits. I'm sure I will be back here for your valued and experienced
assistance during the build and setup. I have searched for and read a lot
of the posts on the list pertaining to assembling Elecraft kits. Thank you
and I hope to use a lot of the information in those posts. If you have any
up front advice in the assembly or setup of the following parts, I hope you
will share it with me.

K3S 100W Xcvr. Kit ; P3-K Panadapter Kit; External Speaker; The Elecraft

Jim,

Amateur wattmeters are notoriously "famous" for their inaccuracies. 
Errors of up to 20% are not unusual, and in many cases it depends on the 
band because the voltage produced by the measurement diodes are 
frequency dependent.

So bottom line, don't worry about the 10 watt differential.  You are 
like the man with two watches who does not really know what time it is!

On the KX3 Yahoo Group question, I receive individual emails (not the 
digest), but something has happened, and I cannot post to any of the 
Yahoo groups that I am subscribed to for the past 2 weeks.  I think 
Yahoo has "gone to the dogs".

Tom,

The best advice I can offer is to:
- follow the instructions as written, they are correct.
- Make certain you use the correct screw lengths (measure them if 
necessary).
- Do not jump around in the instructions, the order presented is for a 
purpose.  Start at the beginning and work to completion.
- Work on one kit at a time.  Start with the K3S and all its options, 
then when working, start on the P3.  Connect them together as shown in 
the Owner's manual(s).

HI Tom,

I, like you, chose to get back into ham radio after many years by building the K3S.

Don suggestions are right on the money.  Follow the instructions to the letter.

I made 3 small errors, all found with the help of Elecraft tech support, and I think with Don?s help as well.  I attribute the errors to trying to work too late into the night.  So, don?t try to overdo and don?t rush it.

I agree with all this advice. I can tell you that any questions you have
will be answered by the fine people on the Elecraft forums, and if they
can't, Elecraft provides exceptional help. I have built three Elecraft kits
and got help from one of the designers on one of the forums, on a weekend,
when I had an issue. You will not get help like that from anyone else.

One thing I do for screws and small parts that are NOT ESD sensitive is to
count, measure and sort them all out into labeled bins of something like a
bead organizer first. Then you know you have what you need ahead of time. I
use the ones with individual round, screw top containers and put little
post it note labels on each. Work on a clean ESD protected surface and keep
the NON ESD parts bins away.

Best of luck and there is great satisfaction in building what you use.

Don's points are very good.?? Add to that the resistance or load value 
to which the power indicator was calibrated.? Ideally it is 50 ohms R 
+j0.? However, being a voltage sensing circuit, any deviation from 50 
ohms will impact the indication.? Thus a 55 ohm load, showing a SWR of 
1.1:1 can cause a 10% error as a higher power indication.?? And with a 
45 ohm load, showing a SWR of 1.1:1, will show a 10% lower power 
reading.? Many ham watt meters are only accurate to about 20% of full 
scale largely to the above as well as circuit components being frequency 
dependent.

That seems odd. I live in a community of about 2000 spread over an area 
of 450 square miles. There is power and phone service to every house. 
Internet is either satellite or over the cellular network. My noise 
level on 20 meters is less than S1 and usually doesn't even move the 
meter. 80 and 40 are typical of atmospheric conditions. Even on my 
full-size 40 meter vertical the noise level is typically S1 to S2.

You must just have some really bad luck. I think I live in a typical 
rural community where the only real noise generator is a cranky electric 
fence.

Got one of those "cranky electric fence" across the highway.? The Noise 
Blanker does a wonderful job of making it go away and not punch holes in 
the signal at the same time.?? Thanks Elecraft!

Message-ID: <1751972122.394353.1512243643323@mail.yahoo.com>

I just got my second K3S and can't get it going SO2R with N1MM+ RTTY

The first K3S runs AFSK through the USB. VOX is used. DTR is used for CW
keying. PTT for DIGI modes is not enabled. Has always worked great. (I did
read the DTR keying won't work in SO2R, but my SO2R will be RTTY only)

I got the new K3S yesterday. Set it up via another USB port. 2nd copy of
MMTTY made. Everything for 2nd K3S set up exactly as for the 1st.

SO2R windows look good. Both radios tracking fine. Digital windows for
both radios decoding fine. Pressing the CQ buttons generate the message
in the appropriate window. There just is no audio coming from the 
soundcard to trip the VOX and neither radio keys.

So I go back to N1MM config tab, and set PTT via radio command for both
radios. Turn off VOX. Pressing a message button now keys the appropiate
radio, and the message is appearing in the text box, but there is no
audio heard and no power output.

Sorry for the space. The problem had to do with enabling the
2nd CODEC in the audio panel. Now both transmitters are being 
keyed, but only with PTT enabled. It still doesn't work with VOX
and I can't here the sent audio in the monitor. And the radios
sometimes hang in transmit. Hmmm...

Bill,

Do you have anything plugged into the LINE IN jack on the K3S?  That 
overrides the output of the CODEC.

Have you adjusted the audio level to produce 4 bars with the 5th bar 
flashing on the ALC meter?  Yes, that is unique with Elecraft gear.

If you are not familiar with that requirement, refer to the article on 
my website www.w3fpr.com.  Scroll down to the bottom of the left column 
and click on the link to get to the page.  My article generalizes on the 
DATA mode application being used while explaining why the Elecraft gear 
is different than other transceivers.  Elecraft support has additional 
information that is more specific for several data mode applications 
should you find you need that.

If you are setting transmit via command, that should be the only method 
enabled - turn off PTT via any other means and turn off VOX.  Using two 
methods together may cause the K3/K3S to hang in transmit (because the 
two methods "fight" each other.

73,
Don W3FPR

A key time and mistake-saver is to be sure to check off each step in the assembly procedure as you complete it. Double check to be sure it was done as stated before checking it off. That is why Wayne has mandated check boxes on all significant steps, so you can be sure where you left off after a break AND to highlight any missed step(s).

An RTTY contests is a great time to try your Elecraft rig?s built-in RTTY capability, either using a keyer paddle or the Terminal window in the Utility application. (Applies to K3, K3S, KX2, KX3.)

The 10 meter RTTY contests starts soon (0000Z), so take a listen if you get a chance. You can use the CW/data message memories to store your callsign and exchange.

dxmaps.com shows some activity on the band today, a good sign. I?ve also seen a few signals popping up in the RTTY segment. Warm-up exercises, no doubt.

I have a blast with my KX3 during RTTY contests.  I sometimes use the QRP Works Ham Central Terminal with my rig, but about two months ago I simply ran the rig sans terminal using nothing more than message memories and a paddle during a contest.  I easily worked about 24 DX countries through a Super Antennas YP-3 yagi up about 20' in the back yard with little effort.

Will have to give the 10M contest a try, thanks Wayne.

Looks like 10 m is acting like 6 meters today -- all the activity is sporadic-E, an all in the eastern half of the U.S.

The ARRL 160 m contest is in full swing. See:

Sounds like Field Day on the band right now, at least in the CW segment. Give it a listen.

Tom ?

I would add only one suggestion to all of the good advice that?s been posted here.  That is, to read everything before doing anything.  I have found it true in pretty much every complex thing I?ve ever done, both professionally and at the radio workbench ? knowing how one piece of a larger project fits into the whole makes it easier to do each piece correctly.  I think anyone who has ever installed a SubRX in a K3 would understand exquisitely what I mean.

A 20% error is not at all unusual in commercial wattmeters either. The famous "Bird" units are only accurate to 5% of full scale. That means that if you are reading 1/2 scale the accuracy is only 10% and only 20% as 1/4 scale. Since Hams tend not to buy all the slugs needed to ensure their meters read near full scale for every measurement, and do not have the slugs professionally calibrated at regular intervals (1 year or so), 20% is a pretty optimistic accuracy at almost every power level.

Jim,

Amateur wattmeters are notoriously "famous" for their inaccuracies. 
Errors of up to 20% are not unusual, and in many cases it depends on the band because the voltage produced by the measurement diodes are frequency dependent.

So bottom line, don't worry about the 10 watt differential.  You are like the man with two watches who does not really know what time it is!

On the KX3 Yahoo Group question, I receive individual emails (not the digest), but something has happened, and I cannot post to any of the Yahoo groups that I am subscribed to for the past 2 weeks.  I think Yahoo has "gone to the dogs".

=== Full disclosure:? This radio?needs work to get it going. ===??
I got it in a trade with another ham a few years ago.??I bought a 4-band filter board for it, and after staring intently at the parts layout diagram?I STILL installed the four trimmer capacitors backwards!? It does work with them?installed this way.? I was told the difference is that the metal screw heads you adjust?are grounded when they are installed correctly.? Otherwise one could probably use a?plastic adjustment tool.? You can also remove them and install them correctly.??
As I recall, the alignment procedures went fine except for?15m, where there was no output.? At this point I put it aside and it has been collecting dust.

And "hamfest" Bird slugs have been found to notoriously be in error.? 
{if they work at all}?? And remember, the Bird meter is a voltage 
sensing instrument and any impedance deviation from the calibrated 
value, normally 50 ohms, will introduce an error in the reading.

The picture of back of the RF deck on the KPA1500 FAQ shows a female DE-15

I ask because I'm inserting a switch box and am making the associated cables

Good Evening,

 ?? Another parcel of cloud pushes its way through a gap in the nearby 
mountains. It slides, tumbles its way down to a low area. Gradually this 
space fills with low layer of mist. As it fills the fog becomes more 
dense. I start seeing waves as an aliquot of cloud hits the ?lake? 
forming in the valley. The gap is about two miles away; the wave caused 
by the tumbling cloud meeting the surface takes about three minutes to 
get to my location. It is still clear and sunny up here but that is 
changing. A misty layer is forming around me. When the wave from the 
last dollop of cold cloud hits my side of the valley the ?breakers? get 
to near my feet. Six minutes per sine wave works out to ~0.0028 
Hz.??There and back again.

 ??? The sun is currently blank though the solar wind is still causing 
aurora. We just missed a CME and are due for another chance on Monday. 
So we will use the ions given us and see how far that takes us.


Please join us tomorrow on:

 ?? 14050 kHz at 2300z Sunday (3 PM PST Sunday)

Thanks Jim.  I wasn't aware the FCC acceptance info was available.  

Unrelated but interesting is that the KPA1500 FAQ puts the typical drive
power at 50W but the average in the FCC tests was 66W.  17m required a
whopping 81W.

Message-ID: <201712030654.vB36s0cM027352@mail47c28.carrierzone.com>

Doug,

I checked 20m about 5pm and noted S3 noise but also that I had the 
PRE turned on.  With preamp off 20m noise is running S2.  But both 
40m and 80m see S6 noise on my inverted-V hung on the tower under the 
triband yagi.  This high for usual on these bands for here (yes, PRE is off).

I looked up your location which is in the mountains near Steamboat in 
northern CO.  2000 pop/480 sq miles = 4 people per sq-mi which is way 
less density from where I live.  4,200 in a 16x 10 mile strip along 
the western shore of the Kenai Peninsula.  Density = 4200/160 = 26 
people per sq-mi.  But that is not accurate for my nearby density 
around a lake with average property size of 2-3 acres and 2.5 persons 
per property.  Probably 200-300 within a mile.  All have wireless 
devices and consumer electronics galore.  Many are line of sight 
across the lake.  I do have buired utilities in the near 1/4 mile but 
overhead wired beyond that.  Internet is phone line DSL and TV by satellite.

Also we have a refinery, LNG plant, and local gas-trubine generation 
station 2-miles to the west.  12 miles south is a city with 7500 
people in typical city density and many stores and businesses (lots 
of digital cash registers).  Another city of 7500 lies another 11 
miles south to the first so in 30-mile radius we have a pop of about 30,000.

I would guess that is not at all comparable to where you live.

Alaska has ground conductivity problems with frozen soil which really 
affects electrical noise.  But if you get out in roadless bush its as 
quiet at you make your home electronics (and generator).

That seems odd. I live in a community of about 2000 spread over an area
of 450 square miles. There is power and phone service to every house.
Internet is either satellite or over the cellular network. My noise
level on 20 meters is less than S1 and usually doesn't even move the
meter. 80 and 40 are typical of atmospheric conditions. Even on my
full-size 40 meter vertical the noise level is typically S1 to S2.

You must just have some really bad luck. I think I live in a typical
rural community where the only real noise generator is a cranky electric
fence.

I would think both amplifiers will have the same connector on the 
production models since the order page lists the same cable (KPAK3AUX) 
for both of them.

My God - if we had a lake, it would be ~ 1/8 acre per property, if you were lucky - 3-5 people per property.

I live in a medium sized town 30 miles from the centre of London, population ~ 250,000 in < 70 sq-mi :-(

Dan: 

The initial prototypes used for photos did have a male DE-15.  That was
changed in a subsequent prototype revision.  The KPA1500 prototype here has
a male DE-15 AUX connector, just like my KPA500.

The K3/K3S to KPA1500 15-pin ACC cable is the same as the cable for KPA500.

The KPAK3AUX cable set includes a Y cable expansion adapter and a TX keying
line interrupter (see KPAK3AUX in the KPA1500 section of our product list),
or the 15-pin cable can be ordered separately without the Y and TX key line
interrupter, see the KAT500 section of our order page, P/N E850463.

Maybe your mic is picking up the fan noise and transmitting it over the air. Try disconnecting your mic and see what happens.

Hi John, 

I am waiting for my K2/100 kit to arrive and start my project as a Christmas
present to myself. I operate a few times a year in Vietnam under conditions
similar to those you describe. My main QTH is air conditioned, but I also
plan to operate from beach locations and some other areas that are not. 

This past year I used a K2/10 and an RM Italy HLA 305V amp which has
external cooling fans without a problem.

But now I plan to upgrade my remote 'shack' with the K2/100, my questions
are...

Would removing the internal speaker and reversing the fan that comes with
the K2/100 so it pulls air through the speaker grill and expels it out the
back provide a similar solution to the one you proposed? Is it possible to
do that?

Did you consider mounting a 4" cooling fan on top of the K2/100 heat sink
that would draw air across and away from the cooling fins? (The RM Italy amp
uses 2 - 4" fans and I never had a heat or noise issue).

Thanks and 73
BJ

James,
I ended up pulling out the 2 meter board and the tuner board (that was
about all it takes to get back to the SMA connector) and really tightened
the inside screw down a lot more torque than I did the first time. I think
I was over cautious when I first assembled the SMA connector. Sure didn't
want to start gouging out the opening in the case! So it has been fine
since then, however I have been a little more carful when moving the KX3
around with the sma right angle and the whip 2m/440 antenna. I think having
a right angle connector there is a little futzy. I have used the radio like
a handheld and just attached the whip antenna to the sma direct (wo the
right angle adapter) and that works fine. It is actually fun! The heaviest
biggest 2 meter ht I ever used since my first HT a Motorola brick lol/
Kinda makes me wish I had gone with the KX2 as It has a built in Mic which
is cool. But I love my KX3. I did design a little attachment that bolts to
the case and that works, but it is rinky dink. but it does make sure the
antenna is supported up from the base so that there is no way it can flop
over then. I will send a pic of that to you and the group if anyone wants
to see it.
Sri it took me a while to get back to you! I need to get my list
subscription back to individual emails, have not been able to keep up with
replies as easy when it is digest form. So Thank You! To anyone else who
replied on this issue (which isn't really an issue just a matter of making
sure the SMA connector is mounted securely).

I did notice that as I tightened it down snug that there was no evidence
that the outside flange (the flange/nut that Elecraft somehow made sure
would turn around the threads, don't ask me how they did that!) Anyway it
seems that the lock washers bite in pretty well and prevents the connector
from turning in the opening. The other option is to look for a beefier lock
washer... not sure if one of those split ring type lock washers would give
more tension? Anyway... I am shopping for some kind of external 2 meter
antenna now, so probably won't be using the whip antenna that much
eventually. Could make a j-pole. I am below ground here so it is a
challenge to get a good signal out on 2 meters. Anyway. thanks again.
probably told you way more than you wanted to read hihi.

73 Merry Christmas to you James~! hope you have a great holiday season. I
plan on Santa bringing me all kinds of ham test equipment. Signal
Generator, Freq counters antennas analyzers you name it.

What is the difference between the KIO2 Rev. B and Rev C, and should I

Bj,

As far as I know, there have been no changes in the KIO2 since its first 
production - and certainly there have been no functional changes.

Where did you see the "rev C" - was it on the board?  Or is it only on 
the instructions?
The Rev designation for the boards does not track the Rev designation 
for the manuals.  Manuals are updated when a part number or part 
description needs to be modified.  The only difference I can see between 
the KIO2 Rev B manual and the Rev C manual is that the length of the 4 
conductor cable supplied in the parts list is 15 feet instead of the 
previous 10 feet.

As a more extreme example, current K2s use the B level boards, but the 
K2 manual is a revision I.

Peter,

Contact Elecraft  support.  I believe they have a Fan filter cap mod.

With 1500W and very good antennas, I worked one KH6, one VK, 3 RA0, 19 
JA, and nothing else anywhere in AS or OC. Thanks to contest scoring 
rules, participants can only work W/VE stations, and the band is open 
from these locations to W/VE for brief periods of mutual darkness, 
peaking around sunrise/sunset at either end. While CQing, I was spotted 
several times in ZL and VK, but only those responses. ARRL 160 is mainly 
for the east coast of the US and Canada to work EU and the Caribbean, 
and most of those stations QRT after EU sunrise. A few of the biggest 
ones stay around to try to work JA.

Let me try this again, I tried to correct a typo and hit send instead.

With 500W and an inverted-L with a too sparse radial field I managed to work two 
EUs, F and EA, new ones for me on 160. I heard OH and SM too but getting past 
the "gentlemen" on the east coast isn't in the cards.? I worked a couple of JAs 
too, but nothing like my friend N7DD, who was running them.? He was hearing some 
that weren't even there for me.

I'm not a contest op but a DXer and pretty much hope that some DX will operate 
in the contests, but they're looking for points and not especially interested in 
digging out weak (but workable) stations..

Even using the RX antenna on receive I hear better than I get out.? I need to QRO.

Hi,

That ought to be fairly straightforward. Connect one antenna to the the
output port of the analyzer and the other antenna to the input port. Then
set the sweep for the frequency range you want to test.

In this case think of the network analyzer as a transmitter with a receiver 
tuned to the same frequency.? Before testing you connect the two together and 
normalize the receiver response to unity at each test frequency. Now connect the 
transmitter port to one antenna and the receive port to the other antenna.? The 
response will be some fraction of unity, which can be presented as % 
transmitted, or more often in dB.

Message-ID: <273F7FBB-D895-4F1B-8F43-2C00830ABA81@elecraft.com>

I have field-test firmware ready for those interested in trying FM mode on the KX2. On 10 meters, FM is useful for both repeaters and simplex FM QRP DXing. For external transverter use, there are programmable band displays (up to 7), as well as a keying output.

The implementation includes PL tone encode (TX), programmable repeater offsets, and control of both overall deviation and PL tone deviation. FM mode can be turned off in the menu if it?s not needed.

If you?d like to test the new release (rev. 2.87), let me know.

I have a K2 with the internal battery option which I trickle charge with 
an A&A Engineering smart charger. I've installed the Smart Charger 
according the method suggested by Don, W3FPR on his web site.

I've had this arrangement for several years and the battery has charged 
faithfully and I have been served well by the charger. However, now I am 
noticing that the two lights on the front of the Smart Charger remain 
on. all of the time.? the green LED is labeled "Charging" and the red is 
"Final Charge" .

Am I to assume that the battery itself is faulty and needs to be 
replaced (it has been in light service for a good number of years...but 
connected to the charger the entire time or is the it possible that 
charger has developed a problem?


Any thoughts on this would be very much appreciatued.

Thanks

We are not having any problems with the Yahoo KX3 group, are you sure 
you are attempting to log in with the correct email address/Yahoo 
account?? I have several Yahoo accounts and I have to log out and back 
in with the correct one to access a different Yahoo group.

Send me an email if you continue to have issues.

Cheers && 73,

Howie - WA4PSC

Is there something wrong with the KX3 group from
Yahoo? I haven't recieved a digest in days and when I try to get into
the group I get an error message Thanks,Jim W7JHR

Tom,

The life of an SLA battery is normally 3 to 5 years.
You can save the cost of shipping from Elecraft if you have a Batteries 
plus Bulbs store in your area.
The may not have the 2.9AH battery in stock (but they will order it), or 
you can use the 2.3AH battery which has the same form factor.

Simple. Connect the analyzer output to one antenna, the input to the 
other.? Set the sweep range for that where you want to look at antenna 
coupling (usually one band for which the antennas are used). Make a 
sweep and tell the analyzer software to display S21 in dB.? S21 is the 
gain of a device or network.

Good Evening,

skunked on neither band.? That counts as a win :)? I was pushed off the 
initial net frequency in each case.


On 14050.5 kHz at 2300z:

At one point on twenty meters I was chasing an ESP K1J? station but QSB 
was deep.? Deep on both bands.? On twenty there was a slow up and down 
signal overlain by a fast flutter.? Forty meters had only the slow QSB 
but plenty of noise did not help.

Maybe the sun will arise from its slumber and hit us with a decent CME

Message-ID: <0ef2bbfe-1089-73a7-58b6-b4ac512d3476@att.net>

I have a K2 with the internal battery option which I trickle charge with 
an A&A Engineering smart charger. I've installed the Smart Charger 
according the method suggested by Don, W3FPR on his web site.

I've had this arrangement for several years and the battery has charged 
faithfully and I have been served well by the charger. However, now I am 
noticing that the two lights on the front of the Smart Charger remain 
on. all of the time.? the green LED is labeled "Charging" and the red is 
"Final Charge" . The K2 meter is showing about 13.4 volts when during 
this time.

Am I to assume that the battery itself is faulty and needs to be 
replaced (it has been in light service for a good number of years...but 
connected to the charger the entire time or is the it possible that 
charger has developed a problem?


Any thoughts on this would be very much appreciated.

Thanks

Tom, WB2QDG

Message-ID: <5A24D874.2272.20DC9FD@Gary.ka1j.com>

I worked the ARRL 160 this last weekend, 
ran QRP. I had a couple technical problems 
that came up, one relates to the K3s. I'm 
asking here first if someone has  
experienced this.

I prefer running the K3s in Diversity in 
the contests. I find it is more helpful to 
take the -3 dB loss (or whatever it is) 
when using diversity than to hear louder 
when only using the one Rx. Diversity 
helps in the tough times to allow me to 
hear almost undecipherable details when 
the band condition collapses.

During the contest the K3s would slip out 
of diversity and leave the Rx at a 
previous point and I would also hear the 
VFO A frequency. It got confusing when 
this happened and no, I didn't bump the 
diversity button accidentally. I was using 
the Marker A & encoder on the P3 to 
navigate me through the signals, not the 
VFO A knob.

I never saw it happening, it would be a 
discovery when I would hearing a call I'd 
worked earlier while onto a new station to 
listen to and I'd see the diversity light 
was not flashing but the sub RX was still 
engaged. I never looked to see if it was 
the last station I worked or back farther.

The one possible time I might have noticed 
something happening was when I heard the 
the effect of listening to the VFO B knob 
turning on the crowded band while 
listening to a fixed signal on VFO A. I 
noticed the effect, looked at the K3s and 
sure enough the diversity had somehow 
unlocked. (What I have no idea of is if 
that sound was someone QSYing or my radio 
QSYing) This happened 5-6 times in the 
contest. It never has happened before that 
I remember.

Also using Win4K3Suite (good program) & 
K1EL's USB winkey at the same time with 
N1MM.

Any idea what might be happening and how 
to prevent it from doing this again?

That is purely an N1MM problem, Gary. The same thing happened to me a few times. It was annoying. I bet I could tell you exactly what button pushes caused it to do that, but I'd have to go think about it some.

By the way, the 3 dB loss at that frequency that you incur from the diversity receive setup is totally inconsequential. You do not give up any sensitivity whatsoever. In fact, it's probably desirable to have the ATT on all the time on 160 anyway, in addition to any splitter loss. See a previous post I made concerning this very question: http://elecraft.365791.n2.nabble.com/When-do-I-need-atten-or-preamp-td7616174.html#a7616249

I pimped both of my K3 with the new KIO3B boards in order to avoid that 
nasty sound card cabeling etc. It works fine via USB but one strange 
thing happens with both radios.

I have to set "PTT-KEY" to RTS-DTR every time after powering down and 
power up the radio again. Both K3 forget the setting "RTS-DTR" each and 
every time. No matter what the computer or the operating system is, 
RTS-DTR always switches to "OFF-OFF" when the radio goes OFF. What am I 
doing wrong?

The K3s does this to avoid the extraneous keying due to activity on the USB serial port while the computer is booting up.  You can put the K3s into USB.SAFE mode like this:
"Safe" mode disables PTT or keying transmissions until the K3S receives a command via the USB interface, such as a read of the rig's VFO frequency.  To turn on safe mode, go into CONFIG:PTT-KEY and tap 1 to select USB.SAFE.  Exit the menu and turn the radio off/on. Applications that use PTT-KEY but don't send commands will require UNSAFE mode (the default). In this case, be sure to turn the PC on before the K3S.

Cheers and 73,

Fred KE7X

Udo,

Are you using the POWER switch to turn the K3 off?
If you turn off the power supply instead, the K3 will not save any 
recent menu changes nor the current band/mode/frequency.

I have successfully used a soundcard output. I used Audacity to create
files with the correct two tone signals. Search for instructions to
generate multitone signals.

I am willing to bet that while trying to hit the ESC key in N1MM+, you 
accidentally or also hit the ~ key immediately below the escape key.? 
That will cause the symptom you described.

.. Logger preserves diversity reception on the K3 unless RX Focus changes
to vfoB at which time the subRX will switch to vfoB (note that in diversity
reception mode, both receivers are using VFO A, so full SO2V functionality
is not available without leaving diversity mode)

To expand on this last point, if N1MM+ is in SO2V mode rather than SO1V,
then any time the focus moves to the VFO B Entry window (including
inadvertent mouse clicks, or pressing the Pause, backslash, Ctrl+right
arrow or Alt+F10 keys), Diversity will be turned off. This might even be
caused by RFI in some cases.

Take a look at the Elecraft Mini-Modules.  There is a 2 tone generator 
kit, the 2T-Gen.  It currently has a Holiday Special price.

Hi

I would like to know if someone tried to run WSJT-X FT-8  in Split mode, not Split in the audio band but in real Split by activating the option in the radio tab of the configuration?

Here, when I activate Split option, K3 change for Split, RX stay on VFO A, TX change to VFO B but TX frequency drop of 1 kHZ !  If I turn the VFO B (TX) 3 kHz up for example, the VFO B return 1 KHz down when a transmission start (TUNE is enough).

This option seems to have been for the DX station rather than for use.

It would be nice to check this before the 3Y0Z DXpedition  that during ...

Hi Dany. This scared me a little bit too until I figured out what it was
for.

This is not just for expeditions. It's for everyone to use whose rig can
handle it.

Your TX frequency will still be as indicated on the FT8 screen. The
software will raise the audio tone frequency by the same amount that it
drops your VFO B so that your tone is in the right place. By doing this,
the audio tone frequency is kept high enough that its harmonics will be out
of your FT8 passband. This is good -- it helps keep the band clean.

See section 4.2 in the wsjt-x user guide.

73, Carl WS7L

Yes there is one around,? I think Wayne sent one out some time back,
Better question is,? how about making 630m a transverter band and
all the settings and switching done automatically as you select 630M.

Plenty hams using K3 on 630M,? asking for an update please for all..

Al, Dan & Rich,

Thanks guys, that indeed is the cause of 
the problem. I have an old hand injury 
that makes using the little finger on the 
left hand a challenge in the typing 
position. I started N1MM+, put the K3s in 
diversity and tapped the key and that 
dis-engaged it. Problem found so thank 
you.

I now have a further problem in that I do 
have SO1R checked off in N1MM and when I 
look at Config > Sub Receiver Always On, 
the line is greyed out and I can't select 
it.

Now that I know where the problem resides, 
I'll see if the N1MM reflector has an 
answer. If not, I'll find what the code is 
for the "`" and find what to write to 
create a scancode map for the keyboard in 
Win 10 to block that function. 

I have done that for years now with the 
caps lock key, I type an entry in the 
registry to only allow caps while the key 
is constantly depressed. That prevents me 
from looking up after typing an opus only 
to find it's mostly in caps & I had 
accidentally hit the caps lock key and now 
I have to re-type everything...

Thank you & 73,

Gary
KA1J

I second Carl's explanation.

I run WSJT-X on my K3s in rig split mode exclusively.   It works
transparently and flawlessly.

Hello,

 Just wanted to let the K2, K1 & KX1 users know that I have some K6XX CW
Indicator kits in stock. Sales have dropped off to 2 or 3 kits a year. When
my supplies run out I will stop selling the kits.

 Please check wb3aal at com for information.

 FYI - This is a SMD kit, not a thru hole device.

Good Evening,

   Another parcel of cloud pushes its way through a gap in the nearby
mountains. It slides, tumbles its way down to a low area. Gradually this
space fills with low layer of mist. As it fills the fog becomes more dense.
I start seeing waves as an aliquot of cloud hits the ?lake? forming in the
valley. The gap is about two miles away; the wave caused by the tumbling
cloud meeting the surface takes about three minutes to get to my location.
It is still clear and sunny up here but that is changing. A misty layer is
forming around me. When the wave from the last dollop of cold cloud hits my
side of the valley the ?breakers? get to near my feet. Six minutes per sine
wave works out to ~0.0028 Hz.  There and back again.

    The sun is currently blank though the solar wind is still causing
aurora. We just missed a CME and are due for another chance on Monday. So
we will use the ions given us and see how far that takes us.

I have to run my K3 (S/N 1260) in split mode for WSJT-X.

It works fine for tone frequencies above 1500 Hz, but for low (<1000 Hz)
tones I can't get the ALC above a few bars with all controls (windows,
wsjt-x, K3) to their maximum settings.

Split 'solved' the problem, so I haven't investigated what is causing the
low frequency roll off.

Hello,

Have you always wanted an Elecraft? A KX1, K1, K2,  whatever? 
I?ll build any of them.

Does your K2 need repair? Tuneup?

In addition to tuning your rig, I can also rescue a building project you might have started some time ago.

See what my clients have said about my construction and service work at 
http://www.eham.net/reviews/detail/6768 

Photos of the popular "Twins" -- the KPA100 and KAT100 in EC2 enclosure --  are at

Hi Steve, 


I have the same problem with inadequate audio from my sound card 
when I use the rear panel Line In connector. But it works great if 
I use the front panel microphone connector.

Hi Frank,

Something seems not right. The output stage of many (most?) computer 
sound cards is usually also used to drive headphones, and typically 
provide at least a volt, which is approximately line level for consumer 
devices, and output Z is usually fairly low (<500 ohms).? In the audio 
world, inputs are, by convention, high impedance (>10K). Did the radio 
designer screw up and stick a low value resistor across the line input?

My general advice is to run the computer sound card about 6 dB below 
clip, because it is common for distortion to rise by 10 dB with that 6 
dB difference in output level. How much drive does that rear panel Line 
In need?

Subject: [Elecraft] Hot Mic when VOX selected
Message-ID: <CAME0jBRRkHX93QjAEyJS+0zCrDm=LYV3vfgE2-bfikn6VVWvUQ@mail.gmail.com>

Greetings,

I wired my spare Yaesu MD-100 desk mic to my K3 - getting good audio
reports.  A very nice desk mic.

However, the way this mic is wired, PTT does not break the mic circuit, so
it's always hot, regardless of position of PTT switch.  My old Shure 444
routed the mic circuit through a pair of contacts on the PTT switch, which
was convenient.  A switch on the bottom opened PTT to enable VOX.

Setting the VOX gain to a suitable level leaves the mic quite sensitive to
false transmits from random desk noises, etc.

Is there a firmware setting or equivalent that will disable K3 VOX when the
PTT circuit is open, and enable VOX when PTT is closed?  That would be
quite useful.

73 and best regards,

Chris - K1AY

Chris,

Think about that for a moment -- If you have to activate PTT in order to 
have VOX, you might as well turn VOX off and operate strictly with PTT.
The "hot mic" is necessary for VOX operation, and one does not have to 
touch the PTT to initiate transmit.

Yes, VOX is not good in a situation where there are random noises in the 
shack, but for those in a quiet shack setting it works quite well - just 
talk and you will transmit.

There are VOX noise gate adjustments that work in association with VOX 
and do work to provide some protection for room noises.

This comment is reminiscent of the years ago SSB contacts where 
operators would make an AHHH sound during pauses just to keep the VOX 
open and not drop out of transmit.

VOX has improved over the years, but is not perfect due to 
considerations beyond the control of the electrons.  I prefer to use PTT 
and not VOX, but VOX can be useful in a quiet shack, especially when 
using a headset with a close talking microphone.

Hi Jim, 


I agree, something isn't right with my K3 Line-in. Fortunately 
the microphone input works perfectly with my Tascam US100 
external sound card. Thanks for your recommending that 
superb device. 


According the the K3 manual, K3 Line-in is designed for 1 volt p-p 
and has 10K input impedance. Someday I'll try a different K3... 


tks

Message-ID: <414986909.2416624.1512542920928@mail.yahoo.com>

I ran through an RF Gain calibration with the K3 Utility-- as I seem to do every three or four years for no good reason-- and then I checked the linearity of the S-meter. I've calibrated my S-meter for 1 S-unit = 5 dB because that way each tic mark represents 5 dB both above and below S9, making it easy to interpret. I use an Agilent E4433B signal generator.


I can go from +60 dB over S9 (-13 dBm) down to S2 (-108 dBm) by stepping the amplitude of the generator in exactly 5 dB steps and over this entire 95 dB range the segments of the S-meter track perfectly.


(The last S-unit, from S2 to S1, takes about an 8 dB delta to register on the S-meter.)


I gotta say, that's pretty remarkable. Not too many years ago S-meters were approximate guesses, but they've improved quite a bit, probably because of digital IFs and lookup tables. Very nice.

I have been looking through the options, and the manual however I can't
seem to find an option to force VFO B to stay on decode instead of
switching back to the frequency. I have been using 0 PWR and the decode to
practice CW however since VFO B switches back it makes it difficult to see
what I have typed unless I am actively looking at it.

Additionally I thought it might be interesting to allow for VFO B knob
while on "decode" mode to allow you to scroll back in a conversation ( to a
certain buffer limit ).

Thank you and I hope to hear if there are any solutions to keep the VFO B
on decode, or if this could be a feature that could be added.

Hi Zac,

You can use the K3  Utility program and its Terminal window to show the decoded characters when you have decode turned on.  You can operate CW, RTTY (FSK D) and PSK (PSK D).  You can define 16 memories for each of the modes by clicking Edit Memories.

Cheers and 73,

Fred KE7X

As some of you may know, I am looking for a K2.

I have received an email from a w9per.rob at gmail.com and he sent me a nice grouping of pictures, seemed legit.
But after some ?blowing up on the pictures? of the paperwork, I noticed he stated the SN is 5526 (in the email text), but the pictures seemed to show 7563.

I just received a very nice email from w9per.bob@ that this radio is not his.

Just an FYI, seemed very legit until the pictures were blown up.

Very first thing to do is look up the call on QRZ.COM.
IF there is no email address listed, consider that a yuge RED FLAG, since the perps look for people who do NOT list their email on QRZ.
Then they apply for a new email with Joe.Blow.W1XXX@ freebie email .com, such as Hotmail, Gmail etc.

They then open a Pay-Pal account using the fraudulent email address and accept payment until thing get a little warm, then they go back to QRZ.COM for a new sucker.

Ryle-of-thumb.....Always list your email address on QRZ.  It's no more secure than  your first name, so don't worry if someone knows.

Also, always look up the seller's call and verify that their listed email address IS in fact the one you're using for a pay--pal account to send money.

I will say it here as we are all friends.
When buying a radio, I ask for the radio to be tuned to a specific frequency
That in itself eliminates some of the problems.

Charles, 
I have one problem with a statement here. QRZ.com is NOT an official
callbook. Only those that sign up or others who have signed up for someone
else are listed. Also, emails change and may not be updated. Basing
someone's credibility on QRZ.com is not a good thing.

 73,
Tim, KQ8M

A more reliable check is the official FCC registry for
a license. Although it does not show an email address,
it does show the correct address.

Find them at:

http://wireless2.fcc.gov/UlsApp/UlsSearch/searchLicense.jsp

Or - just go to FCC.com and search it out.

I think QRZ gets an FCC feed every day after it gets to the ULS. It?s not ?Official? but up to date for FCC issued calls.

Gentleman,

it doesn't work unfortunately. PTT is always "OFF - OFF" when both K3 
are shutdown. No matter if the computer is running prior to the K3 or 
vice versa.

I asked another ham friend nearby with two upgraded K3's, the same 
issue. Could anybody else please try this?

Just use something like Escrow.com unless you actually know the person 
involved.

Ummm ... QRZ.com downloads the FCC ULS at least daily,? If you have a US 
FCC-granted license, you will be there exactly as your license reads.? 
Email and bio are up to you.? We moved a couple of years ago and I 
updated my address in the ULS.? It appeared on QRZ.com that night.

For non-US folks, it *is* whatever they have created themselves.

Udo,

Do you have MCU firmware 5.33 or later loaded?
Did you set the PTT-KEY menu to use "UNSAFE" mode (or activate PTT-KEY 
by other means).
See the Firmware Release Notes for MCU version 5.33 dated 8-03-2015 for 
the full explanation.

73,
Don W3FPR

On a whim, I did about 2 hours of the contest with my KX3 at 5w and the 
43ft vertical with 60' sloping top wire. I've worked a few on cw and FT8 
on 160, but I did surprisingly well with 39 contacts, and got two WAS 
states (IL and VT) to boot! At least I was heard by SOMEBODY!

What about the KX3? Any hope it can at least generate RF on 630, and we 
can clean it up with an external lowpass filter or something?

I think the PIN diodes used for T/R switching in the KX3 cause IMD down there.

A transverter is probably the best approach.

Considering that all I hear down there is broadcast station birdies, I'm

Frank and all,

The K3 Line In needs a signal of up to 1 volt P-P.
The microphone input (either front or rear) need only 1/4 (or so) of 
that amplitude.

Can I suggest that you do not have enough audio from your soundcard to 
use Line In?  Most soundcards can produce enough audio, but it may 
depend on the particular soundcard or which soundcard output you are using.

If your soundcard has only one output jack, go into the audio output 
devices on your computer and change the output to Line Out (it defaults 
to Speaker).

73,
Don W3FPR

I'll most likely use a transverter.?? Base band will be 160M. Likely 
will design and build my own.

Hmmm,
I never submitted any details to QRZ.com, neither did my brother, father and father-in-law et al. Most of the UK entries get set up from a periodic data feed from either Ofcom (UK version of FCC) or RSGB. I had a bit of chasing around trying to get my Father-in-Law and father removed from QRZ.com after they became SK. My Father-in-law's call was being used in a scam based in the Netherlands and I have to say that QRZ.com's admin were very helpful and prompt.
The main issue is that there would appear to be a number of SK calls still listed.

Ummm ... QRZ.com downloads the FCC ULS at least daily,  If you have a US FCC-granted license, you will be there exactly as your license reads. Email and bio are up to you.  We moved a couple of years ago and I updated my address in the ULS.  It appeared on QRZ.com that night.

For non-US folks, it *is* whatever they have created themselves.

Subject: [Elecraft]  K2 paint wanted
Message-ID: <4B0E5D3D5E924915B70BBD4A3B8C0556@DaveLLaptop>

Hi everyone.  I'm restoring an old Elecraft K2 and need some of the grey
paint for the case, but I see it's no longer offered by Elecraft.

 

If you'd kindly take a look to see if you still have any and it's still
liquid and no longer wanted, I'd be pleased to purchase it from you and pay
shipping etc.

 

If you can help, please contact me off list at:  dave at lanks dot plus dot
com

 

Many thanks and 73.  Dave, G3TJP  (QTHR)

Subject: [Elecraft] 48 volt PS
Message-ID: <CE52BA96-F1B5-4269-8C0B-3672FED1B7BD@law.du.edu>

I need to buy a 48 VDC power supply for a project that requires that voltage ? and possibly along with a voltage divider to power the K3.  One suggestion I?ve received is the MeanWell SE 600-48.  The online reviews are good, noting only high fan noise, which can be fixed by replacing the fan with a Vantac Stealth.  But I haven?t seen anything about RFI.

Anyone know this PS who could say something about the RFI question?  Anyone have other suggestions for 48 VDC and at least 12 amps?

Thanks, as always,

Ted, KN1CBR

I use a Meanwell power supply for my amp.  It causes very little RFI on my K3S which is readily suppressed with ferrites.

Well, that makes sense.? I doubt QRZ.com can do that with all entities, 
but it's no surprise that they have it worked out with the UK ... and 
maybe some others.? This is certainly a long way from the "Callbook" of 
the past!

Most of the UK entries get set up from a periodic data feed from either Ofcom (UK version of FCC) or RSGB. I had a bit of chasing around trying to get my Father-in-Law and father removed from QRZ.com after they became SK. My Father-in-law's call was being used in a scam based in the Netherlands and I have to say that QRZ.com's admin were very helpful and prompt.

Hi Ed,

       As a reference point. Elecraft uses a MeanWell RSP-3000-48 in the KPA1500 
power supply as shown on the FCC site.

       Does not show any extra filtering added. Terminals to rear panel 
connector directly.   That is an endorsement of at least that model in my opinion.

The KIO3 in my K3 is acting up.  Does anyone have a KIO3 they'd be willing to sell at a reasonable price?

Please contact me via my email address on QRZ.COM.

One other choice is any paint store or big box hardware store. They can 
scan and custom mix the color with a high degree of accuracy.? I've used 
this approach on several occasions with good results.

I seem to recall that some paint specialty stores can make custom colors 
in spray cans.

And I've used an auto body shop for some cabinet re-paint jobs. Great 
quality and results but usually a bit expensive.

I'm assuming you can spray the material yourself and don't need a spray (rattle) can solution. If you do, I used Rust-Oleum Ultracoat 249078 Satin Granite. It's not an exact match, but not bad.

Here's my K2 setup. The box in the upper right is an EC2 clone I built and painted with the Satin Granite.

I was sharing a table at a dinner at a ham convention (I can't 
remember which one) with a lady from the FCC. She pointed out 
that the only sure way the FCC has of noting the passing of a 
ham is the failure to renew the license after 10 years. She also 
noted that they don't get notifications from the Social Security 
Administration, and really have no idea of the number of living hams.

You probably could benefit from a BC band reject filter.  I bought 
one a few years ago anticipating station on 550-KHz in Anchorage 
might inpack my 600m Rx on 510-KHz.  I bought the Clifton Labs Z10020 
Medium Wave Broadcast Band Reject Filter (540-1700 KHz).
https://www.dxengineering.com/techarticles/dxepressreleases/dx-engineering-acquires-clifton-laboratories

I forget the exact price but think it was in the $60-70 
neighborhood.  Rejection is something like 60-80 dB.

I did see an improvement it the receive noise floor below about 520-KHz

Connect to the KXV3 xvt-Rx BNC jack.  Use of the K3 on 630m requires 
a KXV3 as you transmit in the TEST mode at 1mw thru the KXV3 xvt-Tx 
BNC.  This is good as you will need to drive a PA which will not pass 
received signals.  An external coax TR relay is needed after the PA 
to  bypass RF to the xvt-Rx port.

Many thanks to all who have replied with some good suggestions such as near
matches, mixing grey enamels and using a paint-matching service at a DIY or
automotive store.  Also, Elecraft may be able to provide a paint colour
code: Elecraft, hello???  

 

The liquid-in-a-pot was what I really wanted so scratches could be filled
and corners re-touched.  I find an excellent match and texture can be
achieved by dabbing the drying, skinned-over paint with a finger from lots
of different angles.  This adds a slight texture to the finish and achieves,
as near as possible, an "invisible mend."

 

An old friend, Bill K9YEQ, had an unopened pot that he's sending to me, with
both of us hoping the contents are still in a satisfactory condition.
Thanks, Bill.

 

Rather than using a Sharpie pen to touch in wear and chips on a K3, which
leaves a sort of purple reflective finish at some angles, I found that
Birchwood Casey super black gloss gun touch-in paint in a pen gave a good
and durable match, especially if dabbed with a finger, which reduces its
shine.  This will probably work with any make's black finish.

 

Many thanks and 73.  Dave, G3TJP

Fred,
I have a KX3 I thought this mailing list was specific to KX3. I did however
try the K3 Utility to see if the terminal would output the decoded text
however that didn't work. Additionally while in the field you can't / don't
always have a computer availble for you to decode the text you are sending,
or something that was said a few minutes before.

Thanks for responding. What I am mainly referring to is the fact that it
switches from decode back to the frequency. I would like it to stay on
decode 100%. Is that possible?

I have found that the Rust-oleum Automotive Primer spray can, number 2089
DARK GRAY PRIMER, is a very close match for the K2 color.  Note that the
2081 LIGHT GRAY version is too light.  The 2089 goes on very dark, and is
almost black while wet.

Another option is simply to buy replacement panels from Elecraft.? Not 
as cheap as paint but makes a well-used K2 look brand-new.? That's what 
I did with Tom Hammond's (N?SS) serial number 8.

I have found that the Rust-oleum Automotive Primer spray can, number 2089 DARK GRAY PRIMER, is a very close match for the K2 color.  Note that the
2081 LIGHT GRAY version is too light.  The 2089 goes on very dark, and is almost black while wet.

It is readily available at Home Depot stores.

Re:? I?d settle for a menu choice.

That would be nice.? Something like "STKY DECODE ON/OFF".? Read that as:? Sticky decode display on or off.

The KX3 Utility works well, but requires a compurer.? The PX3 will give you several lines, the Ham Central Terminal and Sidekar give you many more, but detract from the KX3's ability to operate stand alone.

I never use? DECODE for CW, but I would consider it for stand alone RTTY or PSK if it wasn't so distracting.

They were used by many to tap the IF for an external panadapter for the

Two versions available.  One for the K2 and the universal.

My K3 seems quite stable (at least for CW purposes) although I don?t have a TCXO. But there is considerable drift in my P3 for the first 15 minutes or so after turn-on. This is noticeable when the span is narrow (5 kHz). I wonder if anyone has thought about the possibility of stabilizing it?

Message-ID: <d8e0076ef3289c73e6cb2731639a69f4@arkayengravers.com>

Hi guys. Well the move to FL went okay, but it looks like the KX3 does 
not like the sunshine state.
I was setting up for the 10 meter contest, and the KX3 was acting 
'funny'. When I turned it on, the display showed ERR KEY, with no key 
plugged in. Tried EE INIT and reloading the configuration and firmware, 
no change.
So, I removed all the modules, and plugged in the KX3 with a dummy load. 
The display shows d=001 and ERR KEY, nothing else is plugged in.
Firmware is mcu 2.76, dsp 1.50. I can eventually get it into menu mode, 
but it locks up at 'LCD TEST'. Also, if I put it into cw mode, I get a 
string of dots, which does not go away until I shut the rig down.
I think it needs to go back to Elecraft.

Ken WB2ART

Make sure the internal cables are seated. Mine was acting very weird once and that fixed it.

You probably already did that when removing the modules, but it is worth mentioning.

Dear Zac,

I am not sure how it might work on your KX3, but the? K3 will hold the " VFO B decode" window open on both RX and TX. The setting I discovered to get there is press "TEXT DEC" button, then use VFO B to select "CW 5-40" (or whatever speed) then press "TEXT DEC" again. It locks VFO B screen in decode mode during both transmit and receive.?As far as "scrolling back" I do not thik that is possible.

Hi Vic,

I do have the .5 TXCO but also have the 
ref board attached and a GPSDO which 
updates constantly and the software I use, 
NMEATime 2 updates the computer time every 
minute to 6 digits out.

That said, the K3 is always dead on but as 
to the P3, I never have noticed the P3 
doing anything but keep right in line with 
the K3s frequency. I never see any 
drifting when it is cold & just starting 
up.

Might it be your radio drifting for a few 
minutes till it warms that you're seeing? 

73,

Gary

Ken,

That message says the key or PTT jack is active, and the KX3 'thinks' 
the dot contact is closed.

Do you have a microphone plugged in?  If the PTT button is stuck, it 
will cause that error.
If that is not the problem, do you have a stereo 3.5mm plug with nothing 
connected to it?  Plug it into the KEY jack and see if the problem stops.
Check the front key jack (where the KXPD3 plugs in).  Is there anything 
shorting the jack (header).

If none of that helps, contact Elecraft support KX3support at elecraft.com

73,
Don W3FPR

I have made my way to preparing to install the filters I purchased for the
project. I have read (someplace) that I could place the filters on the RF
board skipping the locations that I might later decide to add. With
thoughts of possibly adding narrower SSB and data filters I am planning to
install the FM 13Khz in FL1, the 2.8Khz in FL2, leave FL3 blank, install
the 400hz in FL4 and leave FL5 blank. Are there any disadvantages to this
approach? I'm thinking the FM 13Khz filter will allow me to dabble in FM
and AM (I have typically not been a phone person)?
Thank you,
Tom NB5Q

Tom,

That should work fine.  Just set the menu (or easier still, use 
K3Utility) to set the proper filter widths and offsets.

Good Evening,

 ?? A dusting of snow started this sunny week.? Each night into the 
upper 20s, each day up into the 40s.? Great week to collect wood and 
bring it home.? I have enough to get me through the end of the year now 
to get another two month's worth in before the rains return.? Since I am 
only cutting out dead trees it burns pretty hot.? Hopefully January will 
be as mild as December has been.? The way it is I can heat the room by 
just driving the graphics card a little harder.? CUDA is fun!

 ?? The sun is blank.? SFU is below 70.? I may need to start fishing for 
new times to get better results.? We shall see.


Please join us tomorrow on:

 ?? 14050 kHz at 2300z Sunday (3 PM PST Sunday)
 ??? 7045 kHz at 0100z Monday (5 PM PST Sunday)

 ??? 73,
 ??????? Kevin. KD5ONS

I think that if it were the K3, then I would hear a change in the pitch 
of a signal over the first few minutes, and I haven't noticed that.
I think I'm going to do a more careful test: tune to RWM (the Russian 
version of WWV, which is good and loud here) and see what the change is 
on the K3 and the P3 in the first 15 minutes from a cold start.

The P3 has a reference oscillator that is adjustable in the menu. It can 
drift relative to the K3. I need to do a more careful test to try to 
determine where the drift is originating.

Hi Bill
There is no mic, just power, dummy load and blank 3.5 mm plug into the 
key jack, as suggested by Don.
VOX was off, but just turned it on and off, no VOX on the display.

Now, when I turn on the KX3, ,I get d=001 ERR KEY. Pressing disp a few 
times clears the d=001. As soon as I long press MENU, I get a string of 
dots.

Is that blank 3.5mm plug a tip-sleeve or a tip-ring sleeve???? I believe 
it should be a tip-ring-sleeve type.

I would like to take my KX2 along as a very compact JT65 & FT8 station. Are
there any suggestions for Ipad applications and any tiny sound card
interfaces?

I have a very small sound interface, that I got from Amazon. It 
is about 7/16" thick by 15/16" wide by 1 1/2" deep including the 
USB plug. The label calls it a FG-UAU01A-1AB-BC21 and i remember 
it cost in the neighborhood of $5. I have not used if for 
digital mode operations, but it is adequate for computer 
conferencing. For use with line level signals, it will need a 
level reduction pad.

I believe all the WSJT software needs Windows and X86 instruction set so iOS or ARM based tablets are out. I looked around bit but finally settled on a Dell 12.5 inch Latitude business laptop.  It outweighs the KX2 by 3X but it has three USB 3.0 ports and a bunch of other features. I use it with the KX2, two audio cables and a Radio Shack USB sound card dongle. Couldn't be simpler. YMMV

There are downloadable versions of WSJTX for Mac and linux, so maybe an android tablet would work.

The $12 SYBA SD-AUD20101 is very good. 

https://smile.amazon.com/External-Adapter-Optical-Windows-SD-AUD20101/dp/B006SF68P2/

But for FT8, the built-in audio in a laptop is probably fine.

Tests of external USB audio interfaces are here:

Good Evening,

 ??? Conditions were poor to abysmal.? Slow QSB with moving bands of 
screeching QRN.? Both stations from the Midwest were good one moment and 
down two S units the next.? But it sounds like the worst weather missed 
those of you who could hear me.? Dry conditions for everyone due to a 
sunny week.? While this is helpful to me it's not to those in tinder dry 
California.? The forecasters say rain for later this week; hopefully 
that will cover the entire West Coast.? Even a cessation in the high 
winds would help.

Message-ID: <5A2DE749.13669.3FA5C12@Gary.ka1j.com>

Something I find myself doing frequently 
is use the P3 with a SVGA monitor above 
the K3s, especially during a contest. In 
the heat of the game I find myself all too 
often twisting the OFS knob for the 
RIT/XIT control.

As I rarely use the RIT and XIT functions, 
I would like to replace the OFS encoder 
with the encoder in the P3 so that I would 
be allowed to select this control in 
CONFIG to work the P3 with this knob, or 
as it exists now, for RIT/XIT. 

When I'm tuning with my left hand on the 
VFO A knob, I'd like to be able to control 
the marker on the SVGA monitor with this 
knob with my right hand. I am only using 
Marker A with the P3 during contests, it 
would be so much more ergonomically 
balanced to be able to have both controls 
at the same level and direction. 

I realize this is likely not to be an 
option but if it were, I'd do it in a 
heartbeat.


If wishes were fishes...

When I first turned my new KX3 a few years ago it immediately did as you describe. VOX was ON and the VOX Gain at MAX. Didn?t matter that no mic was plugged in.

Vic,

Remember that the P3 IF is tunable from 455kHz to 21MHz.
That means you can tune the P3 to the RWM signal.  You will not hear 
anything, but you should see the signal on the display and can see how 
much it moves.

Don W3FPR

Ted.

Best to box the PSU and silence the fan with sound deadening material
without affecting airflow.? In effect, creating a "silencer" for the air
inlet, and maybe outlet.

For that sort of power level 500W and above, and the small size of those
PSU's, the cooling is critical for a long life.? So, the gutsy but noisy
fan is there for a reason.?? Replace it with a quieter one if you must,
but don't compromise the airflow.

As to RFI.? All SMPS's create it, some more than others, by design.? It
can be filtered of course, but to do that properly will also cost a fair
bit.

Voltage divider?? Just use a dedicated 12 (13.8V) PSU for the K3.? You
then have redundancy for when the 48V supply quits at some point.?? If
you must, one of the common "Telecom" DC/DC converters, (48 to 15V, and
a linear post reg) to get your K3 supply.

But, make sure you know which side of any such DC/DC converter is
common, if not isolated.? You may be (unpleasantly) surprised!

Remember the KISS principle.

The online reviews are good, noting only high fan noise, which can be fixed by replacing the fan with a Vantac Stealth.  But I haven?t seen anything about RFI.

Before I jump off the deep end, after the SVGA board is installed in the P3,
will the board support a Smart TV that has a 42" display. Also, the TV has
HDMI inputs. What specific adapters do I need to hook the two together
assuming the combination will work?

I've been assembling and testing an ulralight portable FT8 setup for use
with my KX2, although it's based on an 8-inch Windows 10 tablet.  It uses
the *Syba SD-AUD20101* USB soundcard.  It works very well.  I've posted
some notes here:  http://k3s.wikidot.com/ft8sota

Hi Griff, 


A VGA to HDMI adapter will do the trick

Not sure if they are one way - in which case that would be HDMI -> VGA

Negative.  It not only runs on other OSs, inlcuding Linux and MacOS, it
also runs on other ISAs such as ARM.

And to do so the code needs to be built for the specific ISA including
linkage to the needed libraries.

Some have done it and you could ask for references on the WSJT reflector
for experiences.

Looking at the WSJT web site, they have packages for Mac and for an
assortment of linuxes, but not for iOS.  Compiling the source code for iOS
is possible, in principle, but iOS makes it hard.

One of the smaller Mac laptops, particularly a refurb, might be a
reasonable choice.

Message-ID: <00f701d372be$c8288dd0$5879a970$@cox.net>

I have found that I do not get enough use out of my K-Pod to warrant keeping
it so I am offering it for sale.  My shack is non-smoking and no pets.  I am
asking $185 shipped in USA.  Outside USA at actual cost.

Hi Bob,

It's the offset knob at the lower right 
corner, next to VFO B. I agree a dedicated 
mouse to the P3 to do this would be a 
great help.

I'm not interested in moving VFO B, the 
predominant time this becomes an interest 
to me is during a contest and it's VFO A 
with transmit that I am needing to move.

An aside, I love the receiver on this K3s, 
pure magic.

73,

Gary
KA1J

Why don't we tell Wayne it is time to stop tweaking and start telling us what their production schedule is and when they will start shipping. If they intend to ship mid-December then they should have production schedules in place right now.

Why don?t we all just chill?  It?s like waiting for the birth of a baby; which happens, when it?s both ready and in its time. 

It?s cheaper to wait until it?s ready than shipping it back and forth. 

It?s close, you can see the head crowning. ?

But before Bouvet would be nice.

My sentiments exactly Rick.
If it doesn't make it by Bouvet, I still have the Alpha 9500 in line that works perfectly. So, I am in no hurry.

Why don?t we all just chill?  It?s like waiting for the birth of a baby; which happens, when it?s both ready and in its time. 

It?s cheaper to wait until it?s ready than shipping it back and forth. 

It?s close, you can see the head crowning. ?

But before Bouvet would be nice.

Before I beat my head against the wall (or re-invent the wheel); does someone have a micro to setup the K3S (or K3) for WSJT-X.? What I am looking for is:
?1.? Set the mode to?TX Data
2.? Set mic sel to Line In
3.? Set the filter to FL2 (2.7 KHz in my case)
4.? Open up the pass band width to max
I think that is it; but I might have missed something??
Thanks,
Dick, K8ZTT

My experience is that if you set wsjt-x to use rig control, just 
starting to monitor does most of the work. I end up in Data-A 
mode. This automatically sets the mic sel to Link In. I already 
have a macro to open up the bandwidth, which automatically sets 
the filter to my FM filter. My macro for bandwidth is :

   IS 1450;BW0230;

Note that this macro doesn't open up the bandwidth to the full 
4K, which I do by turning the knobs. The K3 remembers the last 
bandwidth I used, so I don't have to manually change it very often.

I hope this helps.

I find that WSJT and the radio configured for DATA does not need any 
macro to accomplish this feat.

Hi everyone,

I've recently got my old K1 out of store only to find that I cannot get 
any RF out on TX.? I've checked the diodes in the ATU SWR bridge and 
they measure up OK but did notice that the basic rig still works with 
the ATU removed.? On scrolling through the ATU menu I found an error 
message E00. Any advice on how to proceed would be gratefully received.

Andrew,

I don't see reference to an E00 error in the KAT1 manual.
But your problem is most likely associated with the KAT1 firmware IC.

It may be that some oxidation had built up on the pins of the IC and 
socket that would not have developed if there was current flowing 
through the contacts.

Try removing and replacing the firmware IC to see if that clears the 
problem.

Don W3FPR

Interesting saying Twan, it is very true.  All of a sudden no one has any
other amplifier in their shack?

Has the KPA1500 been approved by the FCC yet?

Bill,
Thanks for info; you know, I did not know about switching to Data A switches the input to line in.
I have a AM filter, but am not sure with band with FT8 uses, what advantage a wider filter? than the stock SSB filter has.

Subject: [Elecraft] K3 / RF gain - S meter issue
Message-ID: <007701d37458$e29cb060$a7d61120$@net>

Looking for suggestions here from someone that might have experienced this
same issue - - 

 

I have (2) K3 units (not the S model) that are acting different when the RF
gain adjustments are turned fully counter clockwise.

?  Unit one ? s/n 1062: When the RF gain is decreased to full counter
clockwise position the S-Meter registers full scale (60db over S9) as
expected.

?  Unit two ? s/n 1193:  When the RF gain is decreased to full counter
clockwise position the S-Meter registers only S8.

 Facts: 

?  With the exception of the S-Meter readings with RF gain settings, both
units are working fine

?  Both units have ?almost? all mods installed.  If not all, they are at
least both the same.

?  Both units are running the same version of microcode (5.54) (2.88) (2.88)
(1.26)

?  Both units seem to register very close actual RF gain of stations when
connected when tested on the same antenna

?  Both units have the new synthesizers.

?  Both units have second RX

?  In both cases (both units) I can hear the audio level decreasing linearly
as expected as the RF gain is turned counter clockwise

I have tried to initialize the K3 and reload the firmware resulting in no
change to the RF gain / S-Meter readings.

 

Elecraft Tech Support suggested:

?  Calibrating the s-meter ? did nothing

?  Next suggestion ? send the rig to California.

 

Anyone have this issue and fixed it??

 

73,

Bruce N1LN

Dick,

While it is true that the input *can* be Line In for DATA A - it is not 
the default (like on a Factory new K3 or K3S, when you first go to DATA 
A mode you must use the MIC SEL to set it to LINE.  After doing that, it 
will be 'sticky'.

FT8 uses a very wide bandwidth (if available), and using the 13kHz 
filter, you can stretch the K3/K3S bandwidth to 4kHz.  The bandwidth is 
limited to 4kHz because there is a low pass filter that takes away the 
high frequency hiss and noise that is present on the bands, and several 
hams find quite objectionable when listening to it for a significant 
period of time.

While that high frequency "crud" is not a problem for digital modes, 
there is not a way to turn off the LPF.

As to bandwidth for RX, since the transmit data is limited in bandwidth 
to the SSB bandwidth, I see no need to have the receiver BW any wider 
than the TX bandwidth.? Also, the RX low end likely doesn't need to be 
any lower than the TX bandwidth low end roll off.? Of course if you have 
SPLIT selected in the software then the TX can effectively operate lower 
by shifting the VFO accordingly.

Are both units running exactly the same configuration, at least as far 
as S meter and AGC parameters?

Subject: [Elecraft] K3:  2 meter SSB/CW Capability Questions
Message-ID: <EE2D1B55-5A7E-4FB8-BF7D-CD9C1E9BFA61@mac.com>

I would like to have a ?weak? signal, SSB/CW, capability on 2 meters.  I have three ways of achieving that for my K3:

1.  The K3 (K3S) K144XV built-in 2-meter option module at $469.90 (price includes the K144RFLK reference lock board).

2.  The external XV144 transverter at $479.95.

3.  A third-party, non-Elecraft solution which I have not really considered.

First, clarification, I understand that the XV144 works with the K3 and I also understand that it is older technology compared to the K144XV but I have no idea if this matters.  The advantage I see of the XV144 transverter is that it provides higher output at 20 to 25 watts.

What are the pro/con of these two different (items 1 and 2) ways of getting 2-meter capability.  Note: I have no interest in FM.

Thanks,
73, phil, K7PEH

I would first perform the RF Gain calibration using the K3 Utility.? The 
calibration program measures gain characteristics and applies software correction.

Then run the S-meter calibration.

Do you mean the KX1? I always liked that one, reminds me of the portable

One possible way to make a decision is to consider whether or not you might want to try meteor scatter on 2m using MSK144.  The recommended absolute frequency accuracy for that mode is 25 Hz (though I think you'd get away with 80 Hz). This is a real challenge at 2m and the XV144 isn't really up to it, though I have managed a few MS QSOs using a K2/XV144/amp combo.

Phil,

I have had no problems working MSK144 on 2 meters as well as EME using the K144XV internal option with my K3S.

Is the S meter supposed to read 60 over 9 when the RF gain is turned all the way 
down?

Mine reads 30db!

Message-ID: <DM5PR06MB2697918BE0DD26FA624DA5B9BF0A0@DM5PR06MB2697.namprd06.prod.outlook.com>

Many years ago I bought an N1BYT Single Loop Receiver at the Dayton Hamvention. The radio has 3 controls and came with a small single-loop wire antenna that plugs into an NE602AN balanced mixer. Other ICs include an Analog Devices AMP04F instrumentation amplifier, an LM386 audio amplifier, and an LP2951 voltage regulator.

Because of work and family obligations, I set the radio aside and did not use it. Just recently, I found the radio, powered it up, and it works, but I could not find the instruction sheet, and I have forgotten the control functions and basic operating procedure.

If you have instructions for the N1BYT Single Loop Receiver, would you be kind to share them with me? Please reply off list.

Steve and others,

My best 2M MS contact was running the K144XV with the phase lock board 
and a BEKO amp at 800W into a 6el yagi in my attic. Over 1100 miles as I 
remember. It was a good combination.

Hi Bruce,

try to reload the factory data calibration before doing the calibration 
with a generator.

Usually it works.

After reading several posts here about this antenna analyzer kit, I decided to order one on Dec. 2. Got the confirmation immediately, but never received any shipping notice or the product. I have sent two inquires that have gone unanswered.


Has anyone had any experience with the company? Any suggestions?

Nov/Dec 2017 QEX has a very nice article by W4ENE on how typical male voice
waveform asymmetries will cause peak-riding ALC to unnecessarily limit
average power even through compression and other technologies.

I myself had noticed that my voice on an oscilloscope or as seen in
Audacity, has these extreme asymmetries, even larger than the examples
given by W4ENE.

W3AM has a very nice web page on the subject too: http://www.w3am.com/
8poleapf.html

There he illustrates a simple op-amp all pass network that has substantial
phase shift across the male speech bandwidth to ?break up? the asymmetry.

With links to the Kahn Symmetra-Peak, a broadcast radio unit that dates
back the 1960?s.

I?m gonna be building some hardware for myself soon!

With all of the anticipation about the KPA 1500, a timely and informative discussion of that product and amplifiers in general can be heard on episode 38 of the Workbench podcast at Ham Radio 360.

David Shoaf KG6IRW from Elecraft is interviewed by Workbench podcast hosts (and Elecraft product owners) George KJ6VU and Jeremy KF7IJZ. This edition of the podcast does a great job of explaining the design philosophy of the KPA 1500 (and KPA 500) and discusses considerations any ham should think about when planning on adding an amplifier to their shack. 

If you are not familiar, the Workbench podcast is one of three podcasts produced under the Ham Radio 360 umbrella. The Workbench is specifically focused on the hands-on DIY or ?maker? side of our hobby and as such offers a deeper dive into some of the more technical aspects of the hobby. The other two podcasts focus on portable or field operations (great for KX3/KX2 users) and on the hobby in general. Elecraft is a sponsor of the podcast, and I highly recommend them to you.

Message-ID: <320ef269-057f-79f7-f0be-64e20f74963c@aol.com>

I have a similar - but different! - issue on one of my Elecraft's.

I own both a K3 and a K3s.? Both are configured equally with the K3 
having been upgraded to the highest level to achieve near K3s equivalency.

My K3s RF Gain control works exactly as expected, i.e. as the control is 
rotated counter-clockwise the "S-Meter" increases to a point at almost 
full scale.

On the K3, however, as the RF Gain control is rotated counter-clockwise 
and the "S-Meter" increases to about the "40-over" point at the 
control's 10 o'clock position the "S-Meter" then inexplicably drops to 
the "S9" position where it remains for the remainder of the RF gain 
control counter-clockwise rotation.? This shouldn't be but like N1LN's 
issue, the radio does otherwise perform correctly.? I have done 
everything that N1LN has done including the RF Gain calibration using a 
signal generator.

Very strange, indeed.

Looking for suggestions here from someone that might have experienced this
same issue - -

  

I have (2) K3 units (not the S model) that are acting different when the RF
gain adjustments are turned fully counter clockwise.

?  Unit one ? s/n 1062: When the RF gain is decreased to full counter
clockwise position the S-Meter registers full scale (60db over S9) as
expected.

?  Unit two ? s/n 1193:  When the RF gain is decreased to full counter
clockwise position the S-Meter registers only S8.

  Facts:

?  With the exception of the S-Meter readings with RF gain settings, both
units are working fine

?  Both units have ?almost? all mods installed.  If not all, they are at
least both the same.

?  Both units are running the same version of microcode (5.54) (2.88) (2.88)
(1.26)

?  Both units seem to register very close actual RF gain of stations when
connected when tested on the same antenna

?  Both units have the new synthesizers.

?  Both units have second RX

?  In both cases (both units) I can hear the audio level decreasing linearly
as expected as the RF gain is turned counter clockwise

I have tried to initialize the K3 and reload the firmware resulting in no
change to the RF gain / S-Meter readings.

  

Elecraft Tech Support suggested:

?  Calibrating the s-meter ? did nothing

?  Next suggestion ? send the rig to California.

  

Anyone have this issue and fixed it??

Maybe I dozed off during that nearly three hour fireside chat but I came away 
disappointed.? I wanted some meat about things like IMD, an issue Elecraft has 
plenty of, device selection, biasing, power control, matching and so forth.

You guessed it, Bob; you can blame me for the final tweaks. I do most of my operating with small radios that have no fans, so I?ve been obsessing over the KPA1500?s acoustics. 

As mentioned in the last update, we made changes to the power supply fans that dramatically reduced their sound level (by about 15 dB). Then, last week, we applied the same technique to the RF deck, with excellent results. In a 20-minute brick-on-key test on 40 meters, the fans cycled between speeds 2 and 3. Previously it had been speeds 4 and 5. I feel that these changes, which required ordering some different components, are well worth the trouble.

Seriously, you guys are going to love this amp. I?m a QRP guy at heart, but even I have to admit that hitting the key at 1500 W is a bit of a rush, especially on an amp that keys silently, like our smaller radios. And thanks to the latest changes, hunt-and-pounce ops, like me, will almost never hear a fan come on.

My concern would be "does the S meter indicate correctly?"

Thus with 50 uV applied to the antenna input it should read S-9, and 
with 0.78 uV applied it should read S-3, and with 5000 uV applied it 
should read S-9 +40 dB.??? I've checked my K3S at these and other values 
and I'm confident that the S meter is accurate. Hence, I'm confident I 
can give accurate signal reports.? Thus unlike many radios and their S 
meters, they are only good for a rather unscientific and largely 
inaccurate signal report, somewhat like a SWAG.

I ordered the FA-VA4 on Nov 20th and it arrived in great condition on Dec 
8th.
My order was shipped on Nov 24th but I did not receive any shipping notice 
so I sent an inquiry which they promptly replied to with tracking number.
I have not read anything negative about the analyzer, only very positive 
comments.
Merry Christmas to all!

Message-ID: <002a01d37501$f0dd04f0$d2970ed0$@net>

Thanks for the responses ? here are the answers to the questions and
suggestions and a new piece of DATA associated with selecting the SUB-RX.

 

1.       I checked the S-Meter configs for both of my K3s ? they are exactly
the same.

a.       SMTR OF  016

b.      SMTR SC  016

c.       SMTR PK OFF

d.      SMTR MD ABS

 

2.       I then ran RF Gain calibration using ?Factory default RF Gain
Calibration data? as I don?t have the necessary test equipment

a.       Ran for both main and sub-RX

 

?  No change to the symptom on the suspect K3

 

3.       Just for the heck of it ? I reloaded the currently installed
firmware using the K3 Utility 1.15.12.7

a.       MCU: 05.54

b.      DSP (both main/sub): 2.88

c.       FPF: 01.26

 

?  NO CHANGE

 

4.       I then downloaded the most recent firmware ? only change MCU is now
05.60

 

?  No change

 

5.       I then selected the SUB RX ? not sure why.... just did it.

a.       When I turn the RF gain counter clockwise the S-Meter increases to
60db over S9

b.      When I turn the Sub RX off ? the S-Meter only increases to S7

 

NOTE:  I never tried this before, but it appears to be an interesting piece
of data.  Does this now point toward the Main RX in some way?

Bruce ? N1LN

More info.

Thanks to Brian, K3KO, some hints were given to check my particular 
issue.? Thanks also to Bob, K4TAX.

Since I have no intention of opening my radio (as the radio does work 
fine), I have discovered something of interest and a potential cause for 
the symptom I'm seeing.

As I apply a high signal level into the radio, I reach a point where the 
S-Meter behaves exactly like rotating the RF Gain control 
counter-clockwise (the reading drops).? This is easily duplicated.

Brian noted that perhaps what I am seeing is being caused by the K3 
Automatic Front-End Protection modification which my radio had its 
modification years ago.? The mod protection works as designed while 
injecting a high signal level into the K3, and I do see where the preamp 
(if engaged) is disabled.? Furthermore, I see HI SIG displayed in the K3 
VFO-B area.

Interestingly, my symptom happens at the same "signal level" the S-Meter 
reacts to with preamp disengagement, but without an injected signal just 
by rotating counter-clockwise the RF Gain control.? I do not, however, 
see the HI SIG level notification during this test and it matters not if 
the preamp is engaged or disengaged.? That said, the resultant S-Meter 
reading that had been "dropped" does follow both attenuation and preamp 
values.

Brian might be on to something!

Again, no intention of pursuing further unless Elecraft can duplicate 
and create a mod.

73 and thanks for the BW,
Dan

Personally, I wouldn't go so far as to say the radio performs correctly. Without 
writing a long history, let's just say that I discovered this RF gain issue 8 or 
9 years ago.? I demonstrated it to an Elecraft engineer in my shack who had 
brought along his fully up to date K3 which we compared.? They were widely 
different.? Subsequently, I did a lot of beta testing of firmware that I believe 
spawned the RF gain calibration program.

In my opinion based on inspection of the schematic, the issue resides in the fet 
post-filter amplifier that is controlled by the "hardware" AGC (and manual "RF" 
gain control)? The specs on this device are very loose, IIRC, Gm can vary 2:1.? 
Thus the response of this fet to AGC/RF gain varies from radio to radio, and as 
seen in another post, between the main RX and second RX in the same radio.? As I 
understand it, and I would love for someone at Elecraft to correct me if I'm 
wrong, the RF gain calibration program measures the radio gain control 
characteristics and generates a lookup table of correction factors to apply to 
linearize the control.

If I'm correct, I always been troubled by questions about the speed of this 
process.? Being an analog guy I understand resistor-diode networks used for 
similar purposes that operate essentially instantaneously. ? The digital process 
not so much.

Looking for a VFO knob for my K2.  Does someone have an extra they want to sell me?

Subject: [Elecraft] KPA500 - fan noise
Message-ID: <23f3116b-9d9b-8de9-a001-798655363d28@w2blc.net>

Interesting post from Wayne regarding the low fan noise from the 
KPA1500. So, I have to ask about fan noise and the KPA500.

Background: I run my KPA500 all the time - my K3 is a 500 Watt XCVR. 
 From time to time, in particular during AM operation, the fan comes on 
and moves right on up in the noise department. Enough, that I have 
considered changing the location of the amp or redesigning my desk and 
putting a door across the shelf the amp lives on (open to the back and 
lots of room of course).

Question: Has anyone successfully reduced the fan noise of the KPA500 by 
fan replacement? If so, please tell me what you did.

Thanks, Bill W2BLC K-Line

Mike,

Which knob do you have?
There are two shaft diameters.  The one for the original encoder is 
smaller than the one for the new encoder (with a 1/4 inch shaft).

The new encoder will accept the VFO knob for the KX3, and that is what 
is shipping with the new K2 Kits, but it needs 3 stacked felt washers to 
provide a bit of drag on the knob.
The encoder is so smooth that you must have some drag on the knob to 
keep the frequency from moving when you remove your hand from the knob.

The prior knobs are no longer available.

73,
Don W3FPR

I received my KPA1500 late yesterday. Contrary to pronouncements on the forum
by Elecraft, they?re ready to ship. Since I was first to order the amp and
sent in ?something special? to Eric and Wayne, I got mine a week before the
established release to the general ham populace.  Sorry guys, looks like I?m
the lucky one this time.
  
I popped on the 220 connector I needed, reset the voltage to 220 on the PS,
and placed it below my bench on a rolling cart. I ran the cable up to my
equipment shelf, slid the RF deck on my shelf and connected the cable.
Beautiful, matching gray to the rest of the K-Line. I connected the cables
to my K3S, and powered it all up. The display on the amp scrolled ?Elecraft
KPA1500? and the lights flashed through multiple colors until they set in
standby mode. I hit the switch to ?operate,? set the antenna switch to my
dummy load, set RF out to the usual 35 watts on my K3S, and keyed the amp. 
  
What! 3500 watts out?!?! How is that possible?
   
I then noticed a small 3M yellow sticky attached to the side of the amp. I
pulled it off saw a handwritten note from Wayne. ?Lou ? you got a special
first version of the amp. It had 4 finals in it, and a larger power supply.
We plan on releasing it at Dayton 2018, but since you?re a special customer,
wanted you to be first to own this heretofore unannounced beauty. Merry
Xmas!? 
  
I sat back in my chair, stunned. How can this be? What a great present!
  
Then I heard a noise. I looked at the amp, and the display was flashing, in
bright red, ?07:00?, ?07:00?, and there was a loud buzzing. My mind raced,
and I heard my wife, saying ?wake up already and turn off that damn alarm!?
  
I rubbed my eyes after turning off the alarm and realized it had been a
dream. Looks like I have to wait like everyone else. And no 3500 watt
special.
 
Yet?.
   
Merry Xmas everyone! ;-)

Well I told Laura (KF4CXO) that I was getting her something special and that it was so quiet she wouldn't even know what I got her.  I'm working FT8 as we speak on 30 meters and trying to read emails at the same time and not laugh to much.

Thanks for the comments I got and answers to my question (below).  I will probably go with the K144XV plus reference lock board but will wait until it is warmer weather to get my 2-meter antenna up.

This would be easy to test. Normally, 'hardware AGC' kicks in at an input signal level of -46 dBm or so. This point is essentially independent of the AGC THR and SLP settings. See if your K3 varies from this data point anomalously.

__________________________________________
In my opinion based on inspection of the schematic, the issue resides in the fet 
post-filter amplifier that is controlled by the "hardware" AGC (and manual "RF" 
gain control)  The specs on this device are very loose, IIRC, Gm can vary 2:1.  
Thus the response of this fet to AGC/RF gain varies from radio to radio

Al,

My understanding of the hardware AGC is that it is fixed and is not 
dependent on the menu AGC parameters.  The AGC THR and SLP are strictly 
DSP parameters.

The Hardware AGC is there only to protect the ADC from overload due to 
strong signals.

There may some variation in the exact level that the Hardware AGC kicks 
in form K3 to K3 due to component tolerances.

The fact that the manual RF gain operates at the Hardware AGC point may 
be sufficient explanation that the RF Gain Control when at full 
counterclockwise position does not drive the S-meter to full scale 
(again due to component tolerances).

The real question in my mind is whether the K3 S-meter responds properly 
at its calibration points of S-9 and S-9+30.  And those points are 
correct with the RF Gain at full clockwise rotation.  Those calibration 
points are determined in the DSP section, and not in the hardware part 
of the K3.

Don W3FPR

And it works on 30m as well.

I have no 30M power limitations in Canada.  It is just another ham band and
treated as such.

There are several things going on here.

1) The "hardware AGC" is derived at the 15 kHz IF and is designed to 
prevent overdrive to the DSP's IF Analog-to-Digital Converter (ADC).? It 
also serves to prevent the 15 kHz IF amplifier from being driven into 
non-linear operation.

2) The "hardware AGC" voltage is fed to the 8.215 MHz IF amplifier.? By 
placing the gain control here, it also helps to prevent overload of the 
2nd Mixer (8.215 MHz -> 15 kHz).

3) The "RF Gain" control voltage is fed to the same point at the 8.215 
MHz IF stage.

4) The RF ATTenuator (0 or 10 dB in the K3, more choices in the K3S) and 
PREamp (one choice in the K3, up to two choices in the K3S) are applied 
in the radio prior to the first mixer or crystal filter.? They thus have 
an impact on the "hardware" AGC."

All of the above is independent of the DSP subsystem.

5) The "RF Gan Cal" works by injecting known voltages to the 8.215 MHz 
IF amplifier control point and measuring the subsequent change in gain.? 
The DSP measures this and creates a table.? Due to dynamic range 
limitations of the measuring system, the calibration procedure requires 
two signals levels to be injected. In the case of the higher level 
signal not being available, the factory default values are used.? Due to 
variations in the gain control led stage, there may be the change in S 
Meter indication that some of you have observed at high signal (or 
severely reduced RF Gain control) conditions.

In general, if you are going to do the RF Gain calibration, you really 
should use both signal levels.? The XG3 specifically provides the 
required levels.

6) The DSP regularly measures the control voltage to the 8.215 MHz IF 
amplifier. The RF Gain Cal information is used by the DSP when it then 
calculates the signal level in the IF passband.? It is not part of the 
signal control loop; it is strictly a measure and report function.

7) The DSP takes into account the PRE and ATT status provided by the MCU 
in the S Meter ABS mode; it ignores such information in the S Meter NOR 
mode.

8) The S Meter calculation is prior to the DSP's AGC algorithms so the S 
Meter is not affected by THR, SLP or other AGC-related settings.

9) The DSP presents the results of the S Meter calculation to the 
radio's MCU via a DAC voltage that is only routed to the MCU -- it has 
no other function in the radio.

10) The S Meter OFS and SCL values are used by the MCU (not the DSP) to 
manage the S Meter display of the DSP's DAC voltage on the K3's LCD.

Enjoy!

Wes stated that there's a component in the AGC circuit that changes the onset of hardware AGC due to component tolerances. I suggested putting that theory to the test by actually measuring it.

I don't think I said that.? I imagine the onset of hardware AGC is determined 
elsewhere.? What I am saying is that the dB/V gain change is non-linear and 
different from device to device.? I assumed, mistakenly it appears, that the 
bias voltage to the device was tailored via a lookup table to create a linear 
dB/V (if you can call dB linear) scale factor. Lyle's description, if I 
understand it correctly, says that they measure the gain control characteristic, 
but leave it be and correct the numbers via a table.

A much better choice here (IMHO of course) would have been something like an 
Analog Devices AD600 (See "A High-Performance AGC/IF Subsystem" by Bill Carver 
in QST, May 1996.)

Another place where the designers' QRP DNA got in the way of robust design was 
the choice of the second mixer.? The oft repeated claim that hardware AGC is 
protecting the DSP may be true, but the second mixer overload characteristics 
are even worse.

You said, "In my opinion based on inspection of the schematic, the issue resides in the fet 
post-filter amplifier that is controlled by the "hardware" AGC (and manual "RF" 
gain control)."

You were making a relationship between hardware AGC and the loose spec of the FET in question. By saying that, I understood you to mean that the hardware AGC signal was being interpreted differently by the problem K3 compared to a 'normal' K3 because of this FET. At least this is what it seemed like. I will accept that I misunderstood you and that I have no idea what you were trying to say.

This edition of the podcast does a great job of explaining the design philosophy of the KPA 1500 (and KPA 500) and discusses considerations any ham should think about when planning on adding an amplifier to their shack.

The Workbench is specifically focused on the hands-on DIY or ?maker? side of our hobby and as such offers a deeper dive into some of the more technical aspects of the hobby. The other two podcasts focus on portable or field operations (great for KX3/KX2 users) and on the hobby in general. Elecraft is a sponsor of the podcast, and I highly recommend them to you.

Then, last week, we applied the same technique to the RF deck, with excellent results. In a 20-minute brick-on-key test on 40 meters, the fans cycled between speeds 2 and 3. Previously it had been speeds 4 and 5. I feel that these changes, which required ordering some different components, are well worth the trouble.

I?m a QRP guy at heart, but even I have to admit that hitting the key at 1500 W is a bit of a rush, especially on an amp that keys silently, like our smaller radios. And thanks to the latest changes, hunt-and-pounce ops, like me, will almost never hear a fan come on.

Their main business is to publish a monthly ham radio magazine - 
FunkAmateur - , alas their homegrown kit names all start with FA.

I talked to them on the phone last week because i wanted to send back a 
part that i ordered wrong. Most of the staff are hams, they know what 
you talk about when you have questions about their products.

The man -i think it was Ingo DK3RED - said hell broke loose over the 
last days.
Obviously xmas business takes it's toll, the analyzer kit and others 
sell extremely well.

I'm a happy customer for years now and i know the company is small but 
reliable. They never sent a shipping confirmation. Shipping sometimes is 
slow. It's not like amazon where your order is shipped next day.

Maybe your kit is already in the US waiting for custom clearance.

Just relax and wait. If you feel it already took too long, call them by 
phone, their number is  ++49 3044669472. Say you want to talk to the 
shop staff.
Or mail them shop at funkamateur.de . Do not use webmaster at box73.de

Only $10k and possibly a visit from the FCC!

I had a factory built Heathkit Chippewa KL-1 amplifier back in 1965. A 
pair of grid driven 4-400 tetrodes in Class AB1. 10 watt drive for 1KW 
plus, plus out. 3-400Z triodes didn't enter the picture until 5 or 6 
years later. The amp weighed 90lbs and the power supply 115lbs.

Hello Bruce,

Just to rule out any electrical or mechanical discontinuities in the RF
gain control itself, you can use the CONFIG > SW TEST > SCN ADC option to
examine the ADC reading as a function of rotation position for both RF gain
pots and both AF gain pots. In order to be able to see the "SW TEST"
option, you will first have enable  "TECH MODE"  by setting  "CONFIG > TECH
MD to 'ON'

Once you've selected SW TEST > SCN ADC, slowly rotate your rf gain control
from one extreme to the other while watching the 'steps' in the VFO B
display, looking for any sudden step changes. The values I observe run
contiguously from 002 at full CCW to 239 or 240 at full CW.

Good luck with your troubleshooting.

Hi

I have a very nice living room ceiling fan  "Aeratron 50 in. Indoor Silver 3

super high efficiency, very low power and quiet BUT severe radio

Anybody with any experience with these?  They are DC motors, RF ? remote

Dale,

 

Thanks for the suggestion.   I ran the test on both K3s and they are exactly
the same.   The range is from 240 (fully clockwise) to 02 (fully
counterclockwise)   If I turn the RF gain slow enough I can see both rigs
incrementing or decrementing (depending on turning direction) 1 count at a
time.

Several years ago I had a Casablanka ceiling fan which was mounted in a location where the sun would hit it.  During spring and autumn the sun was in a position so the sunlight would shine through the blades then reflect off a white wall and illuminate a small SCR night light.  The blades chopped the light causing rapid on/off switching of the SCR.   The resulting pulsed RFI drove me nuts for three years.  The pulse frequency was a function of fan RPM.  Change your fan speed and see if it effects your situation.

Is this a ham radio beacon? Contact the owner and let them know. It does
not sound like it is in compliance. If not a ham radio thing, still contact
the owner, as it may be suddenly broken.

Best of luck.

I would contact the owner and work with him to resolve the issue.?? 
Likely something near the beacon antenna, such as a metal to metal joint 
that is acting like a diode and generating spurious radiation.? Or if 
the signal is strong, it could be in your antenna system causing the issue.

John,

It has to be fixed at the source.  There is not much that can be done 
with a situation like that at the receiving end - unless as K4TAX 
suggests, it is a strong signal and something in your receiving antenna 
system is acting like a diode detector.

I would ask this another way. What has changed recently. It certainly sounds like the transmitter is at fault, but similar situations can arise in conditions local to your station. Have you changed your antennas? Has something changed in your antennas? Something in the feedline or antenna with diode action could cause a similar issue. This could be a discontinuity in a connection (rust, corrosion) or something similar that is causing mixing of two or more signals. Just disconnecting your antennas and listening with a short whip may not be good enough to find this since you are still interacting with the local issue.

You should take a 6m receiver out and listen to the band away from your station, so that you hear the transmitter without interaction of your antenna system. If you still hear the beacon problems, then the owner certainly needs to know they have an issue.

This can be a rough issue to resolve, both on your end and the transmitter side. So many factors may be involved that the issue gets very complex (such as a diode action on his side, caused by an issue in a local commercial transmitter). Good luck resolving it, but be aware that there will be a resolution.

Remember that the receiver is on all the time, as is the low-voltage supply that is powering the receiver. All can cause problems in addition to the fan PWM that the receiver is driving.

Good luck solving this one. There is not much room in the fan enclosure for ferrites to help resolve the issues and adding capacitors at the appropriate places can be a real challenge. I hope
returning the controller is still a solution for you even if it means taking the fan down?

Hi John

I am assuming that you are referring to K1MS/b in FN42.? I know that 
K1SG,Steve Gilbert, is involved with that beacon as well as K1MS, Ivan. 
They contacted me to design and build a rugged small yagi for that 
beacon as all the previous commercial ones they used fell apart in the 
winter.?? I am sure those guys would help you with the key clicks.? K1SG 
has his email listed on QRZ.com.

Our club's repeater is housed in a mountain-top building surrounded by
a chain link fence.  The site ... which is many years old ... has a number
of other stations, repeaters and several FM BC stations.

The "joints" where the chain link crosses each act like diodes in response
to the intense RF at the site. When the wind blows ... which is often ..
there
is lots of noise heard in all of the receivers at the site.

Yes, there is plastic coated chain link fencing available, but getting it
bought
and installed would be next to impossible.

This from a retired two-way radio tech who's worked at the site for 40
years.

Tom,

The Elecraft website shows MCU 2.89 is the current level for firmware.
Did you click on the Check updates from Elecraft in the KX2 Utility?

Message-ID: <CAB_Vmrx8PwzvdLQw6DgoK_RDqtQEPr52PjhB7g-5zH8Z4uGc8w@mail.gmail.com>

I have a K3 and use a SDRPlay RSP1 as a panadapter.  Last night I noticed a
huge jump in noise and then noticed a strong, wide, cruddy signal every
120hz which would indicate a power supply problem.  This problem is new.  I
have been using this cable for a few years with no problems.  I do not know
the cable's provenance .
I finally traced the source of the noise to my K3 USB to RS-232 computer
connection.
When I disconnect the cable from the K3 the noise disappeared.  The noise
only occurs when the cable is activated.  If turn on the K3 and start
whatever SDR program there is no noise.  As soon as I activate the
connection between the K3 and my computer with OmniRig the noise starts.
The cable appears to otherwise be OK in it's operation.
I don't have another cable to test to see if it is the cable or not so I am
going to order another.
Has anyone else ever experienced this problem?  I'm hoping it's not the K3
Thanks,
Jon WS1K

I'm not as close to the beacon as you but I hear it 24/7 and haven't
noticed anything different from it.  Same chirp it's always had and nothing
else.
Good luck and 73,

 ? Hi Don and all,

 ? In the firmware tab I click on "check revisions now" and get no 
updates. Are the MCU and DSL boxes to the right of the installed 
Available section supposed to be checked?

Many thanks for all the suggestions.  Some points:

1.  I am literally a couple of miles from the K1MS/B beacon.  So, it has always been really loud here.

2.  I did change antennas & feedline recently.  I now have a 9 element LFA at 50 feet fed with 7/8? hardline to the rotor and Messi & Paoloni Ultraflex 13 to the antenna.

3.  I don?t believe that the increased splatter coincided with putting up the new antenna & feedline.  I haven?t experienced any other antenna-related or other events.  The splatter from the beacon is directional.

4.  I will send K1SG an email.

73,

John

Ham beacons are often built with el cheapo grande gear and keyed by 
means that generate clicks. There's nothing in FCC Rules that exempts 
them from requirements to transmit a clean signal.

Contact the owner, let him/her know of the problem, and that you expect 
it to be fixed.

Turn the noise blanker off, to make sure the NB isn't causing the 
splatter.? (Which it can.)

Hi Scott,

The NB actually helps reduce the splatter.

I think I'd at least try.  The responsible operator may not know, and 
might be happy to find out.

I'd offer to assist.

After all, it's not a complaint, it's an opportunity to fix a problem.

I've done a little playing around with this.? I made some measurements, using my 
"old" K3, of the HAC1 voltage (applied to the FET i-f amp) vs. the RFG value 
just to see if I could see the "correction" Lyle spoke of.? It's a 
semi-interesting plot that I tried to post on the K3 Yahoo group. Unfortunately, 
I have a hard time describing Yahoo groups without resorting to swear words, and 
I couldn't accomplish the task. Someday, if I have the K3S out of the station 
line up, I'll repeat the measurements.

By saying that, I understood you to mean that the hardware AGC signal was being interpreted differently by the problem K3 compared to a 'normal' K3 because of this FET. At least this is what it seemed like. I will accept that I misunderstood you and that I have no idea what you were trying to say.

Tom,

Have you checked that external wattmeter at 5 watts?
Many wattmeters when on the 200 watt range may not show any significant 
output until you get to 10 or 20 watts.

Use the 20 watt range on the wattmeter - and do not really trust it at 
the 5 watt level.  The diodes in many wattmeters are a potential problem 
and may not register anything unless the power is 10 watts and above. 
The exception is QRP wattmeters with op amps and compensating diodes.

If you have access to a 'scope with a 10X probe, that is more accurate.
Set the scope to read the RF voltage and connect it across the dummy 
load.  If your dummy load does not allow access to the coax center 
conductor, use a Tee adapter to access the center conductor.
The RF peak to peak voltage for 5 watts is 44.7 volts.

Bottom line - do not trust your instruments (wattmeter in this case) 
until it is proven trustworthy  at the power level involved.

73,
Don W3FPR

I just assembled a new K3S. Covers are on but KPA3 not yet installed.

The installation manual mentions that there may be error messages initially, 
but there were none.

The first issue is that there is no RF being detected on RX, all bands, 
although I can hear the usual background hiss which does not increase with 
an antenna connected.

I also noticed that the KAT3A was not being detected, despite being 
configured as installed. This meant that I could not select Ant 1 or 2.

I firstly forced a power-up reset to ensure there was no firmware 
corruption. I then used the K3S utility to load the latest firmware and went 
on to perform config and calibration.

When it came to setting up Xtal filters there was something odd happening. I 
only have the 2.7KHz filter installed at present in position FL3, intending 
to install the CW and FM filters from my K3 later.
The config showed that position FL1 had a 2.7KHz filter installed, but no 
offset (5 pole filter). I set the config correctly for FL3 position and 
zeroed FL1, but the utility complained about having no filter in FL1, so I 
reconfigured FL1 position as having a 2.7KHz filter installed. I left the 
FL3 position still configured.

Lo and behold the ATU is now recognised and I can select Ant 1 or Ant 2, but 
still no RX. It also fails the 5W calibration.

I haven't been back through the instructions yet (it's bedtime here!) but I 
presume that there must be an actual physical filter installed in FL1 
position and this may be the cause of my issues??

Alan. G4GNX

I get some noise via that K3S to USB computer connection.? I applied a 
ferrite bead, about 1" long, so that the cable actually makes a 1 turn 
loop at each end.? This is one of the snap on beads.??? Cured the 
problem and a couple of others.

The 120 Hz signal somewhat indicates a "ground loop" exists in the 
system.? {What ever a ground loop is.}? Make sure every piece op 
equipment is bonded to a common point, usually the station power supply.

If you are using an Astron linear supply, the 3rd pin ground connection 
may have failed.? I've repaired several of these units where the 3rd pin 
ground wire lug inside the supply was nicely insulated from the case by 
their wonderful paint job.? Correction requires opening the PS, removing 
the lug and screw, scraping away some paint and then put it all back 
together.

Hi Alan,
I am also a new K3S owner/assembler. I had the same symptoms after powering
up the K3S the first time, no errors (that later resolved itself and I
received the KPA3A alert after clearing with Display button and power
cycling several times during Filter Configuration - have 2.8kHz, FM &
400hz). I have also been puzzled by not hearing any signals at this point on
any band, just the noise. However, during the troubleshooting of the
Wattmeter calibration I listened and transmitted with an old Ten Tec Omni D,
I did hear the Omni transmit on the K3S receive and visa versa while
transmitting during the K3S Wattmeter Calibration.
Get a good night's rest and we will press on later!

Tom NB5Q

Message-ID: <CA+03d8jhDc1qe_qegP2-zquujbX1mH3eCyBhkKm+SrHc5fxTGw@mail.gmail.com>

I have an early model K3 s/n 1397 which I built and which I upgraded around
12 months ago with the new synthesizers etc.

It has the second receiver and numerous filters in both receivers.

I have never had a moment's trouble with it since the original build in
around 2009 and since the big upgrade.

However, a couple of weeks ago, I had an ERR 12V message come up in the
middle of a CQ and the rig stopped working. I simply turned it off and back
on again and it seemed to be fixed.

A little earlier today, I was calling CQ on 17m CW using the KPA 500 and
the ERR 12V occurred again.

This time I read the manual and saw that it could be related to the  K3 PA
module.

I powered off the rig again and checked to find that there was some new
firmware which I duly downloaded successfully. I then performed a TX gain
calibration at 5w and 50w and that was successful.

I then did a band by band check of the maximum CW power out. All seemed
normal except for 24.9 MHz where the power out was around 130W - too high.

However, as I was testing on 50.1 MHz the dreaded ERR 12V occurred again
and after a power down and restart the same thing.

Before I enlist the help of Elecraft, can anyone point me in the right
direction to check for a short in the PA module. What should I be looking
at/for ?  The rig has not emitted any smoke nor has there been any burning
smells or unusual noises.

Any pointers would be appreciated before I take the rig apart.

Thanks and 73

Good Morning, Barry:
Sounds like a problem that raised its head quite a while back with 
corrosion of the 12V pins on the KPA3 connector. I am not near my rig 
and info at the moment so I can't confirm that.

Barry,

Contact Elecraft support and request the Gold Pins kit.
Also obtain E560002 which is the KPA3 12V Sense Modification.

You might want to consider other updates to the K3.  See the website 
listing for Spare Parts and Mod Kits for the K3.  Click on "Order" to 
get there.

Hi Tom.

Ya can't always cure stupid (me of course, not you)! :-)

On waking today, it occurred to me that I had not enabled FL3 for RX and 
TX!!! Obviously I'd configured FL3 filter parameters, but totally forgot the 
rest.

I've now removed all of the config and enabling for FL1 until I install a 
filter in that position.

The first obvious thing after enabling FL3 was that even without an antenna 
connected, the receiver sprang to life and I'm quite happily listening to 
5/9+20 signals on 40 metres (with an antenna connected of course).

The 5W calibration worked like a dream and the ATU is now responding 
correctly.

I am now a happy bunny and am happy to have learned something.

Now to fit the KPA3A.......

I hope your issues are as easy to fix.

Hi Alan,
I am also a new K3S owner/assembler. I had the same symptoms after powering
up the K3S the first time, no errors (that later resolved itself and I
received the KPA3A alert after clearing with Display button and power
cycling several times during Filter Configuration - have 2.8kHz, FM &
400hz). I have also been puzzled by not hearing any signals at this point on
any band, just the noise. However, during the troubleshooting of the
Wattmeter calibration I listened and transmitted with an old Ten Tec Omni D,
I did hear the Omni transmit on the K3S receive and visa versa while
transmitting during the K3S Wattmeter Calibration.
Get a good night's rest and we will press on later!

I also have an early K3, ser nr apprx 400 earlier than yours. I got the 
ERR 12V fault a couple of months ago. As others have mentioned it was 
the KPA pins. They were not corroded so much as discolored. I replaced 
them  and the two front panel connectors at the same time.

There's a good blogpost and photos of the front panel connector 
replacement process at

http://wb5bkl.blogspot.com/2012/07/elecraft-k3-p30-and-p35-replacement.html

That should give you a good idea. It looks tedious with all those pins 
but it goes pretty quick if you use a solder sucker. A cheap 
spring-loaded one will do. Also, use an alligator clip to extract the 
cut pins from the board.

Easy when done correctly, & NOT by using a SO239 socket on the output!

That thing should have a 7-16 connector at least on the output.

I don't see any mention of any automatic protection against high VSWR or
other woes that'd damage the tube and/or tuning networks.

PS:? that power level is very do-able all solid state these days, and
with very much higher power's too!?? But...? You'd need an equally
expensive harmonic filter bank, to keep it clean "on air".

I had this problem with #1823 just after I returned from an expedition 
in 2010. (lucky, eh?)
It is indeed a result of the steel pins carrying the 12v to the PA 
becoming tarnished.
Not trusting myself to replace the pins, I opted for the "bypass 
operation" - wire jumpers around the pins (Elecraft can send you picturs 
and instructions). Piece of cake, and works FB.
Elecraft replaced the pins on a second K3 with gold ones when it was in 
for service.
Frustrating when you don't know why it happens, but an easy fix in 
either case.

Whew!? Both bands were rather noisy.? Waves of scratchy QRN moved 
through the frequencies.? QSB was medium to deep, but slow.? When I 
checked 14050 kHz before the first net I heard K1ECU calling CQ very 
clearly.? If I would have had the time I would have replied. I moved up 
to 14050.5 kHz to hold a space when three stations popped up each 
calling CQ.? So I moved down to 14049.5 kHz and found a free spot.

On 14049.5 kHz at 2300z:

NO8V - John - MI

W0CZ - Ken - ND


As I was tuning in on forty meters I found lots of activity.? One op on 
7045 kHz so I moved up.


On 7045.5 kHz at 0100z:

W8OV - Dave - TX?? clear and loud after so long an absence

K0DTJ - Brian - CA?? calling for rain clouds to travel southward with 
his KX2

WG7V - Marv - WA? strong signal once again

K6PJV - Dale - CA? gave me a weak RST - I do believe the bands are long 
tonight

W0CZ - Ken - ND?? off until next year

AE6JV - Bill - CA?? noise was trying to cover you but it did not


Until next week

Hi Alan,

That's good news! Glad you went for a walk and had a revelation, I think I
need a little longer walk perhaps! I'm still having problems but gathering
good data for help I hope. I have enabled my modules and filters but still
no received broadcast, WWV time signal or Ham traffic. Hence I have not
done the Reference Oscillator Calibration and not able to do the Wattmeter
adjustment although I do get a 14.050 Mhz 15mv RF signal (and a 7.050 Mhz
signal at 60mv-only a 20 Mhz 'scope) at the proper respective frequencies
when TUNE is pressed but VFO A has no effect on the output signal according
to the oscilloscope. Am emailing K3support at elecraft.com and hope they find,
as you say, that they can cure my 'Stupid' :-)

I'm confused as to getting these messages on the Elecraft Reflector, I hope
this one makes it.

Thank you to everyone who replied with advice on my problem.

The advice all points one way so I will have a look at the KPA power
connection pins over the holiday period and then do the necessary repair
with replacemnt pins from Elecraft as required - or just hardwire them as
per one suggestion.

I will advise the outcome when I have resolved it.

Thanks again to all.

It is cheap and accurate after OLS calibration with good loads. Attached 50
Ohm load was so so. I am using it when accurate impedance measurements are a
plus, including for LC. For instance with 160m antenna, measure, prepare
appropriate coil or capacitor, and the match is perfect.  

On the other hand, navigation is difficult with 3 buttons. Also not rain
resistant. No computer connection. 

If absolute low cost in not an issue, RigExpert AA 55 Zoom is much easier to
operate, is as accurate with OLS calibration, has tons more functionality
including cable testing, and is not much bigger or heavier.

Interesting project. One thing seems a little odd. You use an attenuator to 
reduce the level of the 28MHz signal as it would be too much for the 
transverter to handle. You then say you then need to amplify the transverter 
output because it only puts out 1mW but you wanted 100mW.

It makes me think you could simplify things if you used a different 
transverter that would give you the higher output since you are only talking 
100mW. It could let you eliminate the 28MHz attenuator, the 1mW to 100mw amp 
after the transverter, or possibly both.

Great job! In the pdf you "hope it will help anyone thinking about microwave IF rig alternatives." If you can go up, you can go down. I've been researching 630m solutions to help a friend get on that band. Unfortunately, I think I caught the bug. Your solution to microwaves, looks like a way to use my spare K2 to get on 630m. The Europeans are far ahead of us there and homebrew transverters for 2200m and 630m exist, though they will probably have to be outboard and not mounted on the top cover.

Thanks for the post.

Steve,

You might want to try building up part of the K60XV as part of your 
project.  Download the K60XV manual and its errata and look at the parts 
list - you would need to add the K60XV firmware (and use MCU firmware 
version 2.04 if you do not already have it).  You would not need the 
changes under the RF Board to add 60 meters, nor would you need the 
relay and bandpass filter components in the upper left of the schematic.
You would need the components in the lower right of the schematic so you 
could control the low power output with the power knob.  All connections 
to the K2 are via RF Board J13.

That addition would allow you to remove the attenuator and automatically 
switch in the 1mW output whenever you select a transverter.

You may be able to obtain a bare K60XV board from Elecraft at a decent 
price.

Don W3FPR

Looks good, Steve,

I did something similar a number of years ago. I put a? low power DEMI 
xverter in a pair of K2s but ended up with a birdie that was pretty 
loud? near 145.1 MHz where we had our microwave calling frequencies. I 
ended up removing the xverter and put it in a different enclosure along 
with band switching to select up to six different transverter bands all 
selectable from the keyboard of our logging program.? It was great for 
home station use, but having 144 built in to the K2 box is a nice 
feature for roving.

With our transverter idea, we bypassed the K2 PA circuits and used a 
lower power takeoff point for TX. It drove the transverter just fine.? 
As I recall, we had a switch on the K2 to select the low power takeoff 
mode.

I hope to work you some more on your roving trips. I missed last summer 
due to an extended illness, and only recently have I been well enough to 
be active with hamming again.

Message-ID: <1010944576.722018.1513628069067@mail.yahoo.com>

There's been several good points made about my K2 internal 2m transverter project...here's a bit of my thinking about why I went the way I did:

(1) Using an alternate transverter (VE3SYB) - I did consider the Transverters Unlimited board from the Ukraine to potentially give me more output, but in any case it would require some modification to reduce the output from several watts to 100 mW.  In the end, since I had acquired the quasi-DEMI transverter at a flea market already, I decided just to go with it.  

I think it would be pushing the state-of-the-art in high-level mixer technology to make a mixer which would directly take ~ 1 watt in and produce 100 mW out at 144 MHz, without either pre-attenuation or post-amplification, but it might just be possible.

(2) Using the K60XV transverter interface (W3FPR) - I thought about that option and eventually decided against it, primarily because of the extreme sensitivity of the K60XV output to RF signals getting into it and causing the K2 receiver to shut down (an odd quirk of the circuitry and firmware). Using a modified version is an interesting possibility which didn't occur to me - maybe enough space could be freed up to build a filter or buffer amp on the original board to fix that problem! I do have a K60XV in my other K2 which I have used with good results on 50/144/222/432 MHz, but it does require an external filter on the output RF jack to prevent weirdness from happening when other nearby transmitters are active!

(3) K1WHS interface (K1WHS) - I suspect this is much the same as what DEMI made for a while before the K60XV came out (and it was much cheaper than the K60XV, too).  N2CEI was nice enough to give me one after they stopped producing them.  I tried it but decided I missed the full Elecraft-style front panel RF power control which it did not support.  I recall Dave telling me years ago that the K2 made a pretty good IF radio, so it's been in my mind since then!  I can confirm that I too get a group of strong birdies near 145.1 MHz, but as I am using 144.1 MHz as my IF this is not a problem for me.

(4) Internal 630m transverter (KE6US) - sounds like a great project! For 2200m, maybe not, as one might want better frequency accuracy in such a narrow band than the K2 can provide.

Steve,

Re: Low Power takeoff point in the K2.

A low power output from the K2 is available if you simply remove jumper 
W6, BUT (and a BIG BUT) is that the power takeoff will be uncontrolled.
You have to drive the VRFDET line to send the power level back to the 
MCU to control the power - the K60XV detects the RF voltage and 
amplifies the DC level with the components in the XVTR ALC portion of 
the K60XV schematic.  So, if you do not use the HF bands, you could 
eliminate a lot of the K60XV circuitry.

Steve,

Nice article on how you modified the K2 to be a 144-MHz IF for use 
with mw transverters.  The venerable IC290R was used by many for a 
long time.  I hear of some using the FT-817 which is selectable on 
144-MHz output for 0.5/1.0/2.5/5.0w.  I had one that I used to drive 
a DEMI 10-GHz transverter with either 0.5 or 1.0w.  But when the KX3 
came out I could see it was way superior radio to the FT-817 and 
makes a nice 144-MHz IF by addition of the 2M module.

I now have a 2w PA on 10-GHz which drives well with the KX3-2M + DEMI 
transverter (10mw out).

So anyone that does not have a K2 to convert might look at the KX3-2M!
<Wayne: you can just mail my sales bonus - ha ha>

Seriously like the KX3-2M.  It dedicated as mw IF and HF/6m mobile 
operating with KXPA100.  At home is usually monitoring 6m for DX 
openings.  I run a 150w TE linear amp for 2m-SSB mobile with the KX3-2M.

<psst - I will be doing 10G portable mw from Copper Harbor in the UP 
(MI) next August><from Longmont, CO RV CG I will be running 500w on 
6m during July CQ-VHFContest>

Brand new never installed K3PR6 six meter preamp.

In factory box with all pieces originally included from factory.

Plans changed and decided not to try 6M after all.  Too many other irons in the fire.


$90 shipped CONUS.  If not sold for $90 by Dec 23, will sell to highest offer received by 2359Z Dec 23.

Message-ID: <CABS7SRAv=hexDnoB70aM3FWa2uWZpeBPLMOfO_4avg1cXHdr0w@mail.gmail.com>

At the ripe old age of nine my K3 developed the ERR 12V problem (in the
middle of a contest, of course). I've seen posts here where owners had some
trepidation about the difficulty of the fix, which is to inspect and
replace some connectors using parts from KPA3CONMDKT.

Relax. It's a bit tedious but it's easy. If you've had any experience at
all with through-hole rework I wouldn't hesitate.

Have a beefy soldering iron handy just in case. Some of the pins were hard
to remove with a small iron. A 40 W iron with 1/4" tip made short work of
them. A circuit board vise or a helper to hold the  KPAIO3 board while you
work on it is also a big plus.

Radio and operator are both happy again.

John,

See the K3 manual menu listing for LIN OUT.
Set that menu parameter to "=PHONES".
The level will be adjustable with the AF gain.
Also use the MONitor knob to adjust the TX level.

Yes, RX audio will also be present.

It creates garbage in your transmitted signal when ALC wiggles. If you keep drive power set low enough that ALC doesn't activate, it's okay. 

Better option is to use the K3's xmit inhibit line if your amp supports it.

Thank you for the information, however I just want to reduce the 
possibility of excessive voice peaks via ALC, not to do compression via 
ALC.

We all make errors, and I would like to reduce the possibility of 
hitting the amp too hard on voice peaks in the event I miss adjust the 
K3 output level.

Dave,

The K3 does not overshoot due to the way output power is controlled (it 
is different than other amateur transceivers in that regard.
So unless the amplifier contains protective circuits which activate the 
ALC for excessive SWR or other amplifier faults, there is no need to 
connect the ALC line.  Even if the amp contains such protective 
circuits, adjust the ALC in the amp so it does not activate with normal 
operation.
Set the power so the amplifier is not overdriven.

If the ALC is activated in normal operation you will be creating 
excessive IMD in your transmit signal - you can hear a lot of that going 
on during a contest weekend.

The K3 has a menu setting (PWR SET) that can allow you to set the 
maximum power on a per-band basis.  You can use that to avoid 
overdriving the amplifier.

73,
Don W3FPR

As a rule ALC is not needed and is not recommended by Elecraft. The K3 
power management system with the internal ALC is far superior to the 
derived voltage from most all amps.?? And, unlike many radios which when 
operated with reduced power, they do have a propensity to overshoot, the 
K3 series has firm ALC control at all power levels.

Just tune and load the amp for maximum output and then reduce drive 
power from the K3 to attain the level of power you desire to operate.? 
And as a note, after tuning and loading to maximum output, do not 
re-tweak the controls for or at the lower power operation.? This is a 
common misunderstanding among hams.? If it is linear at 1500 watts, then 
reducing drive, it will be linear at 500 watts.? If one re-tweaks at 
lower power it most likely won't be linear at 1500 watts or any lesser 
peak there of.? It will more likely be a "splatter generator".

The problem I've had in the past using ALC in that manner is that it was transparent to me that ALC was limiting output power. So unless I happened to notice, or someone local pointed out my wicked key clicks, I was unaware. Using TX inhibit, I get the same result of protecting the amp, but it happens in a more spectacular way with red fault indicators so I know the operator messed up. Not sure if ALC will shut down the exciter as well as TX inh if there's a jumper, feedline, tuner or antenna problem.

That's a great feature. The problem I have is going from running without amp at 100W to driving amp and forgetting to reset levels. So human error (at least in my case) is easy and requires some protection. I also run 2 different 6m amps, one for terrestrial and another for EME, with different drive requirements. As noted I use tx inh with good result.

This assumes one has a (tube) amplifier with Tune/Load controls.

But *much less efficient*.  The output network will be adjusted for
peak current/minimum voltage conditions of maximum output while the
typical (average) voltage/current will be much different.

While it will not be "linear" at power levels above the level at which
the output network was tuned, it will certainly be "linear" up to that
point *and much more efficient* (less loss in the output network).

Don,

Thank you for the information here...  My amp, (the ALS-1306, solid 
state), I believe does use the ALC to shut things down in the event of a 
failure of some sort...

Here is a cut from the ALS-1306 blurb page:

"Output power is automatically reduced to prevent amplifier damage by 
controlling ALC to exciter."

That does not tell me exactly what triggers ALC action, but it does tell 
me that they are using ALC as a form of protection...  As such I want to 
use ALC.

I think I like your idea of adjusting the Amp to not issue ALC during 
normal operation, that way, if something goes way wrong, the ALC may 
still be able to shut things down.  Fortunately the Amp has both 
metered, and front panel adjustable ALC.

I think I will also adjust the Max power for all bands as well...  I 
just finished the install of the SWR/signal monitor thing-a-mabob in my 
P3.  I also have an outboard demod I built, which I can feed into the 
scope to do a bit of monitoring during setup...

Too all the rest of the folks that made suggestions thank you as well!!

73s and thanks,
Dave

Don, et al.,

I did a bit more reading on the Ameritron site, and on other forms, it 
seems the 1306 only uses ALC for overpower, which the K3 can contain 
with the adjustments you mentioned, so no need for the ALC cable!!

Thanks for letting me know about the menu sets for this.  I had not run 
across them, and I thought I had looked at every menu setting there!

Dave

Sometime back around 1970, I built an amplifier for my college radio 
club.? I spent many, many hours trying to get ALC to work, and failed 
completely.? Fortunately, the exciter really couldn't overdrive a pair 
of 3-500Z's, so we ended up running it just as Elecraft recommends, 
using only the exciter's internal ALC.? I'm sure amplifier designers no 
know a lot more about it than I did back then, but apparently closing 
the ALC feedback loop around an external amplifier is still difficult to do.

As I understand and was taught, the amplifier ALC came about as the 
result of exciters having the ability to excessively overdrive the 
linear amp.? Case and point, the Collins 32S1 transmitter would produce 
about 150 watts output when correctly tuned and loaded.? That was about 
twice the required power to drive the matching 30L1 amplifier.? Many 
ask, why not just turn the power down?? Well the 32S1 is a tube 
transmitter which has lowest IMD and best efficiency when tuned and 
loaded to the correct value. In order to prevent overdrive of the 30L1 
amp, the amp ALC signal was fed back to the 32S1 to reduce the power to 
the correct level via the intermediate stages , while the tuning of the 
exciter PA, 32S1, remained correct.? And thus today we do have amps 
which have the ability to provide ALC back to the exciter.

It is of note that many modern day transceivers have ALC circuits which 
do prevent overshoot at rated output.? Unfortunately some of these, when 
operated at less than rated output, have a faulty ALC system which does 
briefly allow ALC overshoot.?? Using ALC from the amp back to the 
exciter has been found not to be successful in controlling this 
overshoot issue as the control element is too far down stream in the 
system.? Just look at the spectrum of many signals using an SDR receiver 
and spectrum display.? You'll observe a bit of splatter on the first 
word or syllable of many signals.? This is attributed to ALC overshoot 
in the respective transceiver causing brief over drive of the amplifier.

Message-ID: <FE7CDA5CDAC64BBCAD5A9862233367B5@RogerOLD>

Just recently my P3 is showing a carrier with-in the SSB pass band. It is quite strong and it is always there, even with no antenna connected. It is particularly annoying on CW, where it falls exactly on the expected receive frequency. It moves with the VFO, so it is always in the same place in the pass band, but it does not produce a tone in the headphones. I seem to remember reading that there is an adjustment to get rid of this, but I can?t find it in the P3 or K3 manual.

Roger, Interesting!

I have seen this on my relatively new P3 on initial turn on. The "phantom
carrier" (great description),  sweeps from left to right just after turn
on, and usually disappears off the right hand side of the screen.

In very hot weather last weekend, the phantom executed its usual move but
remained in view with the display width set at +/-100.

 - yes it follows the VFO
 - looks like a (very overdriven) carrier, but produces no tone.

Interested in understanding this.

Thanks,

Henrik - VK2HHS

Subject: [Elecraft] KX2 as a remote front panel for another KX2, KX3, or K3S?
Message-ID: <DC5B0494-C7A8-4CE5-A457-EA3B2AC2D50B@elecraft.com>

A number of KX2 owners have asked whether they could use the rig as a ?terminal? to control a remote radio. This may be possible to a limited degree. 

This can already be done with a K3, K3S, or K3/0-Mini. All three can do 100% control of a remote K3 or K3S, including 1:1 display mapping.

On the smaller end of the scale, you can use a KX3 in ?RIG CTRL? mode to do limited control of a remote KX3, K3, or K3S. Page 28 of the KX3 owner?s manual provides more information on this. A small number of basic functions is provided, including VFO, band change, mode change, AF gain, etc. 

The rigs can be connected together with a null-modem TTL/RS232 cable (2 wires + ground) or through a simple server app. Receive audio, mic, and keyer paddle must be handled separately from the control stream.

The question is whether there?s enough interest to justify adding such functionality to the KX2. Like the KX3, the KX2 would only provide certain basic controls.

We?re open to discussion about this (on the list or to me privately). Please include a short description of the application you have in mind. It could be as simple as this: using a KX2 on one side of a large shack to control a K3/K3S on the other side. This would be my motivation, since my primary work computer is out of reach of the K3S setup.

Dave, I had an ALS-600.  I sold it as I was buying up to a THP-2.5 1.5KW amp.  The 600 lasted in the hands of the next buyer for less than a year.  The THP was fantastic and I sold it before the purchase of the KPA500.  I was concerned about repairing it with the company out of business and it didn't always fault in the condx you mentioned.  While it was built to be cast iron, I did not want to take a risk.  The KXPA500 amp is what I am using now and would like to come up with $'s to buy the KPA1500 in a flash because the 500 so easily corrects my errors in a flash, and I do make errors... wrong antennas, etc.  It continues to function better than my previous two amps and shuts down in a flash if any of the two conditions you mention exist... including overdrive, wrong antenna or I screwed something else up.  My post is to advise, you get what you pay for and newer technology exists to protect an amp.  Love the 500 and will buy the 1500 when funds are available.  I think the 500 is one of the best amps out on the market.  Again, you get what you pay for and I would rely on the Elecraft brand before all others, esp., MFJ.  MFJ exists in my shack for many devices but not for a SS amp, IMHO.

Don, et al.,

I did a bit more reading on the Ameritron site, and on other forms, it seems the 1306 only uses ALC for overpower, which the K3 can contain with the adjustments you mentioned, so no need for the ALC cable!!

Thanks for letting me know about the menu sets for this.  I had not run across them, and I thought I had looked at every menu setting there!

I have a K3 that I've upgraded to a K3S with the synthesizers and the KIO3B
kit.

I set up the WSTJ software and K3 by following K8ZT's procedure 
https://docs.google.com/document/d/1-yBKo9Fr1NmwG4AaV0jiI6LbtiMysYGVLPqw2LDG
8kM/edit#

Receive works great but when I try to transmit a tone using the "tune"
button on the WSTJ software I get the PTT signal of no tone (audio). 
I have a feeling that there is a K3 menu that is not set correctly. 

Any suggestions would be appreciated.

Hello Tim.

Same way as the original one. Its only inserted on encoder axis. In
original there is additional tightening piece of metal "ring", I printed my
one in way that they tightly fits, its also light so they dont need any
grub screw.

Thanks Joe! 
It was item #1. Ironically my Microkeyer II was plugged into "line in"
I would have lost some more hair (that I don't have) finding that one.
Thanks

You could certainly have configured WSJT-X to use your MK II by
following the example in:
    <http://www.microham.com/Downloads/MK2_WSJT-X_Setup.pdf>

Connecting any plug to the KIO3B "Line In" jack disconnects the output
from the sound card on the KIO3B board.

Subject: [Elecraft] KX2 Offset I.F.
Message-ID: <CAGVQ4X_4-kAxZ=97O55WF7idqoqgXY1svoh-yFv5kRKiqueqow@mail.gmail.com>

Hello group,

I received a new KX2 from Elecraft  a few days ago and I am really enjoying
the little GEM!

As many of you already must know, the receiver performs brilliantly. I have
been comparing with a couple of SDR receivers in the shack and the KX2 is
preferred for weak signal reception in any mode.

I plan to use it portable of course, but for now have it set up in the
shack with an SDR receiver tracking with it as a panadapter.

I have noticed that the KX2 produces about a  -74dBm signal into the SDR
that is connected in parallel to the same Rx antenna (through a T/R switch).

The signal is offset about 8 kHz from the VFO , so the KX2 must use the
offset full time where it was a menu option on the KX3 I had?

For anyone using a similar setup I wonder if you see the signal at about
the same power level?

Am I correct that the nulling or supression is done at the audio stage
within the KX2 (because I can't hear it when I tune the 2nd VFO to it in
Dual Rx)?

Thanks Elecraft for another great transceiver and thank you all on the
group for being there as a great resource!

Mike,

The KX2 is fully an SDR with the "computer" in the enclosure.  Yes, it 
has a permanent 8kHz shift, so all the DSP operation is conducted at 
8kHz (not audio), including the nulling and suppression.

You are hearing the actual VFO freuency - it is 8kHz from the operating 
frequency of the KX2.

If you turn on the preamp, the locally heard VFO signal level should be 
reduced.  The KX2 is designed to operate normally with the preamp on.

If your KX2 and your other SDR receiver are close to each other, you 
could be hearing some leakage from the KX2 circuitry rather than from 
the antenna alone.

73,
Don W3FPR

I have a couple of questions regarding upgrading it. 

How can I tell if the mods (as opposed to upgrades) have been done? 

 

In addition to adding filters, I'll be installing a KSYN3A, and K-Pod (power

How hard is it to install the upgrades, and do I need the anti-static mat,

Hi Don,

Thank you for the great explanation.

I must have had the ATT on when I did the original power measurement
(rough)  on the SDR

I tested again and this time I get:

-77dBm - Preamp On
-55dBm - Preamp Off
-74dBm - ATT on

Just relative differences with the absolutes unique to my setup of course.

The VFO signal is in the noise with the antenna disconnected from both KX2
and SDR.
The VFO signal is lower when using separate antennas for each as would be
expected.

I was just not used to seeing a signal like that when using the SDR to
track superhet's before, so it had me scratching my head for a bit until I
considered the Rx architecture of the KX2(3).

Thank you for helping me get everything organized in my thinking, sometimes
that is a monumental task!

Eric.

Firstly, you absolutely MUST use an anti-static mat, suitably connected to 
ground and an anti-static wrist strap. Whilst you might "get away with it" 
without those items, you may cause unseen damage and you won't know until it 
breaks down. I know the manuals state that you can "touch a metal object", 
but that's very hit and miss.

I upgraded a pair of K3s earlier this year and I used a combination of 
guesswork and observation. Most of the mods and upgrades come with 
sufficient instructions to tell you what you are replacing, so that you can 
look and see if it's already been done. If you know the pedigree of the K3, 
you may be able to guess by the mfr date of the K3 and the date the mod was 
issued. Otherwise, just remove all covers and take a good look at each 
component to be replaced/added. All mod instructions are available from 
Elecraft as downloads, so you can check before you order parts.

SMD capability is useful but not essential, although you will need an ESD 
safe soldering iron with a fine tip and probably a good magnifying glass.

I can send you a list of all the mods and upgrades I performed, if you care 
to send me a pm.

Wayne,

This sounds interesting. My station is located in a fourth bedroom, downstairs, at one end of the house. I use a K3/P3 mostly for CW operating and a KX3/PX3 connected to a Raspberry Pi for primarily for data modes. They share my meager array of wire antennae via two coax switches. With a wife and two kids here, I don?t want to spend all my time at home hidden away in my ?man cave? - aka the shack. In the past I had taken the KX3 out of the shack into the family room at the other end of the house, strung up a temporary wire antenna in the back yard trees and fed it with some coax run under the door sill. That let me do a little CW while still being in the room where the ?action? was. But disconnecting all the cables, rigging up the antenna, and then re-connecting the cables got to be a PITA, so I pretty much gave up on doing that.

This past summer I got that nifty KX2 and added it to the shack. Now I alternate between the K3 and the KX2 for my CW operating. I have to admit that the KX2 sees more on the air time than the K3! Anyway, the KX2 has been used in the family room on occasion, but I still face the antenna install and de-install issue, along with that antenna not having nearly the performance of my big doublet at 45 feet. It would be great to use the KX2 to run the K3 remotely and have the benefit of a much better antenna, along with the option of ?QRO? at 100 watts if I wanted. But, does such a setup allow one to use CW, and if so, how the heck does that work? A 90 foot, multi conductor cable attached to the keyer paddle? :-) :-)

Mike,

Think of the 8kHz shift similar to a low frequency (8kHz) IF if your 
thinking is along the lines of a superhet receiver.

Of course, the KX2 is *not* a superhet, it is a full SDR.  If the "IF" 
were at a higher frequency, the VFO would be further away from the 
signal frequency - by the frequency of the IF.

The SDR DSP processing is at 8kHz in the KX2, or selectable between 
baseband (zero frequency) and 8kHz in the KX3.

Using baseband has some advantages (the roofing filters), but also some 
downsides such as increased exposure to strong radio broadcast signals 
leaking into the baseband stream.  If you have ever experimented with 
Direct Conversion receivers, you will know about that breakthrough.

An SDR in simplified form is two identical Direct Conversion receivers 
operated 90 degrees out of phase with each other.  That allows the 
signal processing to be done mathematically (whether that be analog or 
digital).  A study into the Phasing Receivers of Rick Campbell KK7B 
design along with op-amp mathematics will give you the analog version of 
that signal processing.
The problem with analog implementation is that real components have 
tolerances that must be dealt with - digital mathematics can be exact 
calculations.

Eric,

It may be a good consideration for you to send it to Elecraft for upgrading.
The Elecraft technician will alert you to the subtle things that could 
be upgraded, such as the encoders used for the small knobs.
The result will be that you then have a K3 that has not only been 
upgraded, but will have been run through the factory automated test and 
burn-in station.

You will also be given the opportunity to add some of the K3S upgrades 
if you want such as the KXV3, new synthsizer(s), and the KIO3B for 
direct connection to a USB connection rather than RS-232.

If you chose that route, contact K3support and request an RSA.

73,
Don W3FPR

Hi .?I was wondering if anyone could explain something to me please. If one has a Panadapter like lppan or sdrplay attached to if out the k3, and you transmit, you see the transmitted signal displaced a couple of kHz higher. Why exactly would this happen? I have some ideas but I am not quite sure.?Thanks.?

This is a valid point. I don't think all vga to hdmi converters are created equally.?Also the svga output from the p3 at 1920x1080 doesn't work on any of my monitors so it would be interesting to know if that would be the case when it is converted.?73 Tom?

I must disagree.? All the digital processing takes place after the 
quadrature mixers.? Up to that point, it IS a single conversion 
superhet, but with two mixers with quadrature outputs. The same is true 
of the KX3, though it can be operated as a direct conversion receiver, 
which is simply a superhet with a zero frequency IF.

This is in no way meant to disparage the design of the KX2 or KX3:? They 
are truly excellent radios.

I'm going to respectfully disagree.? The problem is not the static or 
the ground, the problem is when you have a differential voltage between 
items.

If you always maintain a forearm on the frame of your device and handle 
things carefully while maintaining contact with the frame, you will all 
be at the same electrical potential.? Be sure to be in contact with the 
frame when opening anti-static bags, too. Hold boards by the edges, 
don't finger the gold contacts, and don't touch components if you don't 
have to.

This technique has worked for me for years.? I don't do sensitive work 
often, but I never seem to have all the 'anti-static' stuff when I need it.

The only danger is if you get carried away and lift that arm.

When working on tube gear, keep one hand in your pocket. When working on solid-state gear, keep one hand on the chassis.

But a static mat is cheap insurance for when you need to scratch your nose.

Amazon has one for $11. I think I paid more for mine at Fry?s, but whatever.

I agree.  I was a total neophyte when I assembled my K3S.  I used a cheap mat and wrist band.  Never had a static failure.  As Walter said, cheap insurance.

Yes, and/or perhaps you add some charge that you brought to the party.

Be sure to be in contact with the frame when opening anti-static bags, too. Hold boards by the edges, don't finger the gold contacts, and don't touch components if you don't have to.

Possible, but hard to accomplish in some situations. Ambient conditions (humid vs arid) can make a big contribution to the potential for electrostatic discharge.

> This technique has worked for me for years.

I assume that means you have never seen the correlation between ?it was working, I did something to it, there was a spark, and now it does not work?.  This observation is common.

Damage form electrostatic discharge is often incremental - the damaged part keeps ?working? but sometimes not as well as it used to - this falls int he category of ?incremental?  static damage and can degrade the performance of the device, part, circuit, or system. Sometimes you have measure the performance carefully to ?see? the damage - or take the top off the part and use an SEM.  I changed the way I think about this, and work on electronics, based on a collection of photos that an analog engineer I worked with in the 80?s showed me.

In a simplistic example, a small discharge can blow a gate in a 24 bit A/D converter which then fails to correctly report the result, or an opamp to loose gain or add noise, often in small steps.


>  I don't do sensitive work often, but I never seem to have all the 'anti-static' stuff when I need it.


That is simply a matter of being prepared?..  My approach is similar to the one I use for trauma kits: scatter them around in the likely places - as someone else said, it?s cheap insurance.

Subject: [Elecraft] Bounced emails
Message-ID: <1607fc0883e-1719-27a5@webjas-vab064.srv.aolmail.net>

Hi Gang:


I received today a message, supposedly from the list mom, saying that I had "too many bounced emails" and that my membership in the list was being suspended.


Can't figure why the emails should have bounced.  Unless somewhere in the bowels of AOL/Verizon that there was a major hiccup.  Other lists and direct emails appear to have not been affected.  


There is a simple "relpy to this message" to supposedly restore my account, but I'm concerned that it might be a hack that is being re-directed somewhere else.  I have not yet responded.  But, the message could be legit, since it had my list password.  Of course, sending a password in a plain text email is not such a good idea.


Maybe it all was a hiccup at Mailman.

This is a valid point. I don't think all vga to hdmi converters are created equally.
Also the svga output from the p3 at 1920x1080 doesn't work on any of my monitors so it would be interesting to know if that would be the case when it is converted.

Tom,

That is the result of the transmit signal leakage into the receive IF 
output.  If it is bothersome, a relay operated with PTT to break the IF 
output would be in order.

It is not a true representation on the final transmit signal because of 
shaping circuits in the K3 transmit chain following the leakage point. 
So it cannot validly be used to analyze the final transmit signal.

Scott,

By your definition of an SDR, that may be true.
Some SDRs today are direct sampling at the antenna, but think back to 
SDRs in the recent past when high frequency direct sampling was only 
achieved at great cost - the simplest example is the SoftRock 40 which 
used a quadrature mixer to baseband.
I think most would say the Softrock is an SDR.

Don't trust a "reply to this message" link. If the email said "relpy" 
instead of "reply" that is even more reason not to trust it. You can check

Dale and all,

I would add to that --
When working without an antistatic mat, how much charge is on the tools 
that you pick up?
Also where do you put any removed boards to assure that they do not 
accumulate a charge?

An anti-static mat is cheap insurance.

Tom,

That is the result of the transmit signal leakage into the receive IF 
output.? If it is bothersome, a relay operated with PTT to break the IF 
output would be in order.

It is not a true representation on the final transmit signal because of 
shaping circuits in the K3 transmit chain following the leakage point. 
So it cannot validly be used to analyze the final transmit signal.

With respect, this is just arguing semantics.

It does not matter where the (considerably high) voltages come from or go 
to, they still exist and need adequate precautions to prevent damage.

Stand on a stepladder, then rub your hair with a balloon, touch the ceiling 
then "hang" the balloon on the ceiling. Touching the ceiling should have 
discharged and high voltage potential, but the balloon still "sticks".

Did you ever try to complete a lengthy project whilst keeping part of your 
anatomy constantly in touch with the frame, or try to open an anti-static 
bag with one hand 'fixed' to a stationary point?

I prefer to spend a few dollars on good insurance, rather than wonder 
whether I may just have lifted my arm at the same time as I shuffled in my 
nylon underwear. :-)

AFAIC the instructions in manuals to touch bare metal, are a there to inform 
those who insist on not taking adequate precautions, at least make an 
attempt to discharge themselves.

I'm going to respectfully disagree.  The problem is not the static or
the ground, the problem is when you have a differential voltage between
items.

If you always maintain a forearm on the frame of your device and handle
things carefully while maintaining contact with the frame, you will all
be at the same electrical potential.  Be sure to be in contact with the
frame when opening anti-static bags, too. Hold boards by the edges,
don't finger the gold contacts, and don't touch components if you don't
have to.

This technique has worked for me for years.  I don't do sensitive work
often, but I never seem to have all the 'anti-static' stuff when I need it.

The only danger is if you get carried away and lift that arm.

Karin,

The AUXBUS is Elecraft proprietary and is used to communicate between 
the MCU and all other firmware devices in the K2 system.  So your 
"Strange bit streams" are not likely to be related to WSPR controls.

If WSPR gets the proper data on the RS-232 signals, the KPA100 or KIO2 
will pass those signals to the MCU (in TTL compatible voltages) using 
pins 24 and 25 of Control Board U6 (TXD and RXD) - in turn the MCU will 
either operate the proper K2 circuits directly or communicate with 
whichever option firmware IC is needed to complete the request.

What faulty operation are you experiencing?  You can email me privately 
or send your reply to the reflector.

I have had experience with the K2 since 1998 and regularly service the 
K2 (about 3 a week this year) and have never had to debug anything on 
the AUXBUS except to verify that it is producing pulses.  Even though I 
do some of that work for Elecraft, I do not have access to the AUXBUS 
protocol, nor have I needed it.

In other words, the AUXBUS has no relationship with the K2 serial 
communications, so I believe you may be looking in the wrong area.

Don W3FPR

Karin;

Please elaborate on exactly what you are trying to do and what you are seeing.

The AUXBUS data stream is not a part o the CAT system, and is used only internally for
communications between our modules. If you are seeing CAT issues, then I strongly
suspect something else is going on. One thing to remember with the K2 is that the
AUX I/O connector carries more than just RS-232 signals, and when connecting the
radio to the computer these non-RS-232 signals MUST NOT connect to the computer
DE-9 connector at all, or very bad things will happen.

The auxbus is activated briefly on band changes to update transverters and the KRC2, whether present or not. It?s possible that during auxbus activation, the K2 may be missing an RS232 character or two. (Interrupts are locked out.) I?d have to dig into the K2 code to determine this. 

The auxbus handler was rewritten in the K3 so it can?t miss such traffic.

Karin,

Jack makes a very valid point.  If you are not using the K2 to PC 
special cable to the AUX IO connector that removes all but TXD, RXD and 
SIGNAL GROUND from the RS-232 cable, the K2 may display "strange 
happenings" or in the worst case can cause damage to both the K2 and 
serial port.

Message-ID: <A65869F9-B44D-40B5-B67D-D40DE7D62966@liberty.edu>

Probably a dumb question. New to using pan adapters, and just got my PX3 put together.

I hooked it up to my KX3, tuned around on 40m (using a home-brewed AS-2259 NVIS type dual dipole for 40m and 80m) and I get really strong signal indications close to 19khz both above and below the center frequency on the display. It doesn?t matter where I tune in the band. If I adjust the scale, the signals stay at the +/- point of about 19khz. They appear stronger than any other signal in the display.

I am running the KX3 off internal batteries, and the PX3 off a LiFePO4.

Are these signals from something outside being picked up in the cables between the KX3 and PX3, a problem with the PX3, or something else (like, maybe, me)?

Jeff,

Have you done the Opposite Sideband Nulling (page 26 in the manual).
Make certain the RX IQ plugs are fully seated at both ends.
See Trobleshooting on page 33 in the manual.

It doesn?t matter where I tune in the band. If I adjust the scale, the signals stay at the +/- point of about 19khz. They appear stronger than any other signal in the display.

For data modes (PSK-32, FT-8, etc.) you don't need to move the radio.

Raspbian supports VNC natively.  There are VNC clients for just about 
every operating system including Android and Windows.

Sit in the living room with your laptop or tablet, jump across your 
network using VNC to get to the Pi, and operate.

Wayne,

Do I understand correctly that KX3 can be used in combo with Remote Rig 
set as a remote head for K3? You state that basic functions are 
supported through CAT and then receive audio, microphone and keying can 
be supported by Remote Rig. To me this sounds like? there should be no 
problems. Or do I miss something?

I?d really like to be able to use my KX2 to control my KX3. Is that an option or is only the K series the lucky one?

Nope - didn?t get that far in the manual. I was just too excited to read any more.
Looks like those parts address my question pretty well. Thank-you much Don.

I would very much like to be able to use my KX2 as a remote control head
for my K3. Some usage details below:

- Use the RCForb software (remotehams) to control my K3.  So if the KX2
supported terminal mode, I believe it would be able to remote control any
rig via RCForb.

- Having the built-in paddles send CW via the KY commands (and also ideally
by having them generate the RTS/DTR serial port signals used by RCForb for
local paddles) would be great as well.  Local side tone generated by the
KX2 would also be great.

- In my opinion, integrating the audio back through the KX2 speaker is not
important at all, the computer audio works fine.

- Even though the KX2 control set is smaller than that of the K3, it would
still be very nice to see the display and use some of the knobs/buttons to
access some of the more useful controls.  The KX2 is designed with a lot of
pragmatic attention to conserving space, so those knobs are typically all I
use most of the time anyway.

I'd be happy with any subset of the above features. I currently use a K3/0
Twin which takes up a fair bit of desk space, and would prefer to use my
KX2 for controlling the remote station most of the time, particularly for
casual operating or DXing.  The operating position where I operate from
when using the remote setup is a smallish desk with a slim iMac and not
much extra space.

Jim,

The critical timing is handled between the Pi and the radio.  If network 
delays slow the display, that's generally not critical.

You raised digital modes.

I've spent a bunch of time ragchewing back in the day on AX.25.  PSK-31 
is good.  My impression of FT-8 is that it isn't good for ragchewing, so 
I can't get excited about it.

Network delays could be an issue for CW.  I don't know, I haven't made a 
CW contact in at least 4 decades.

It might work for JT9 and JT65, but the speed with which one needs to get things done in FT8 makes me wonder if that is feasible at all. The VNC connections works great, but there IS a small amount of latency involved. And as you know, one doesn?t have much ?fiddle time? when it comes to FT8!! That, plus the fact that after having used the JT modes for a few years now, I am getting sort of tired of them - not really much of a mode to actually communicate with the other guy - simply an exchange of signal report and grid square - gets boring after a while. Quite useful for nailing down new DX, grid squares, or states, but falls extremely short for rag chewing! I guess I?m just an old CW guy at heart!

Jerry,

Just plug it in, and it should work.
With a single lever paddle, there is no difference between Iambic A and B.
Have you tried it?  If so, what problems did you have?

Be aware that some "antistatic" mats are just pieces of soft vinyl without any real antistatic properties. 

One of the Elecraft engineers studied several mats and came up with the following information included in the newer Elecraft manuals:

"Typically, a mat will have a resistance of up to 1 Gigaohm (109 ohms). Testing a mat requires specialized equipment, so we recommend that you choose an anti-static mat that comes with published resistance specifications and clean it as recommended by the manufacturer. 

"Testing has shown that many inexpensive mats that do not specify their resistance have resistance values much too high to provide adequate protection, even after they were cleaned
and treated with special anti-static mat solutions.

"Suitable anti-static table mats are available from many sources including:
? U-line (Model 12743 specified at 107 ohms)
? Desco (Model 66164, specified at 106 to 108 ohms)
? 3MTM Portable Service Kit (Model 8505 or 8507, specified at 106 to 109 ohms)"

I agree.  I was a total neophyte when I assembled my K3S.  I used a cheap mat and wrist band.  Never had a static failure.  As Walter said, cheap insurance.

Yup, that was me.  The Radio Shack portable mat in particular is one 
that my testing showed to have too high a resistance to do any good.

The one Walter mentions (below) is probably OK.  The Amazon page 
specifies "Surface resistivity: 10E9 - 10E11 Ohm/m2" and it mentions 
that the back side is black and 1.8 mm thick.  Good mats have a 
highly-conductive back side to properly distribute the charge.

I agree that using an anti-static mat and wrist strap is good insurance. 
  The reason for grounding it is to make sure it is at the same 
potential as any grounded device (such as a soldering iron) that you may 
be using.

Don,

I'm not sure there IS an accepted definition of a "Full SDR" radio, but 
it's just a matter of semantics, anyway.? I just wanted to point out 
that the KX2 and KX3 use local oscillators and mixers to convert the RF 
to the IF, like any superhet.? From there, it's pure SDR.? (Perhaps 
aside from the analog "roofing" filters in the KX3.)

Now, if a radio used a high speed ADC to digitize the incoming RF 
directly at something greater than the Nyquist rate, I'd call that "Full 
SDR".? So far, high resolution ADC's really aren't fast enough for the 
high end of the HF spectrum.? Direct sampling is sort of a gray area, I 
suppose, as the undersampled ADC really acts like a mixer, and needs to 
be preceded by a bandpass filter to eliminate the undesired alias products.

73,
Scott K9MA

Hi all, I am resurrecting my K3 > N8LP pan setup for some testing.  I have a Xonar U7 and have misplaced the audio cables to go from the Pandadapter box to the U7.  Does someone have a readily available list of the best/simplest cables to go from the N8LP pan to the Xonar U7?  Seems anything I am finding is some kind of multi-adapter hack job.. wondering if someone out there has a good cable solution?  Also would be interested in what the most popular/current pan adapter software folks are running these days on Win10.  I am sure PSDR IF stage is probably long retired to the boneyard.

I'm sure that it meant 10^6, 10^7, 10^8, 10^9 ohms.  106-109 ohms is low

For me a software-defined receiver is one where the demodulators and filters are implemented (defined) in software. Adding a synchronous AM detector is 100% software.

We already have precise terms for receiver architectures: superhet, direct conversion, and TRF (no conversion). Direct sampling receivers are essentially TRF designs, sometimes with very wide bandwidth. The simplest TRF receiver is a crystal radio. Well, I guess ?talking light switches? (corroded connections detecting strong AM broadcast) are simpler.

One could design a receiver that used direct sampling with dedicated hardware for demodulation. I would not be at all surprised to hear those had been built for the military or the space program. They built hardware Viterbi decoders, after all.

So far, high resolution ADC's really aren't fast enough for the high end of the HF spectrum.  Direct sampling is sort of a gray area, I suppose, as the undersampled ADC really acts like a mixer, and needs to be preceded by a bandpass filter to eliminate the undesired alias products.

I build all of my cables with quality connectors and quality cables. For 
audio cables, I use miniature coax that I scored at a ham flea market 
many years ago and connectors that I buy from Full Compass in Madison, 
WI. The good brands are Switchcraft and Neutrik. Part numbers are listed 
in this link, beginning with slide 192.

Message-ID: <000001d37c33$a59de0c0$f0d9a240$@snet.net>

I downloaded and installed v 2.89 a few days ago (KX2 s/n 1003) and decided
to give the FM mode a try - you know how it is, 10 m FM repeaters are not my
thing; but since the feature is there, I'll have to try it!

 

I found exactly one 10 meter FM repeater in this part of Connecticut and
proceeded to enter the usual parameters, including the offset, PL et al
following the v2.89 notes.  All worked as intended and I even spoke with
someone through that repeater.  All was fine, except he reported my audio to
be quite low.  OK, let's follow the instructions and boost the FM deviation
- but that menu item just plain doesn't exist as far as I can find!  Has
anyone else had this experience?

 

Dick,

My K3/100, S/N 4385, is at Elecraft for repairs. Since it is at Elecraft and will be at least partly disassembled, is it worth considering the addition of the KIO3B, while it?s being worked on? I already have the upgraded synthesizer and have added the KRX3A, also with the upgraded synthesizer. Will this get me fairly close to the specs of a K3S? I already have the filters I need and the internal ATU.

The unit has been accepted at Elecraft but I don?t believe any work has started yet.

Dick,

Turn on Tech Mode and you will see that menu item.
In my opinion, if you will be the only one accessing the menu, just 
leave Tech Mode on.
However, if someone else is using your KX2, or if you have a habit of 
pushing buttons before you look, turn it off after adjusting those menu 
entries.

In the menu listing (manual page 40 and following), those menu items 
that are shown with a 'padlock' symbol are not visible unless Tech Mode 
is turned on.

Phil,

First of all, do you need or want it?

I have chosen not to add it to my K3 because I have plenty of RS-232 
ports, and I have a good USB soundcard already.  Note that I use a 
desktop computer at the home station - it sits on a shelf on the back of 
my custom made operating table, and I find a laptop on the desk cumbersome.

But if you are operating with a USB to serial adapter, or want to 
eliminate the extra USB cable to the soundcard and the 2 audio cables, 
you may want to add the KIO3B.
The KIO3B brings both the USB to serial adapter function and the USB 
soundcard functions inside the K3 and operates them both with a single 
USB cable.

Don W3FPR

Hello all,

It's been years since I did any serious kit building, and I've been looking
for a good winter project for a while now. So, when I found an unbuilt K2,
KPA100, and KAT100-1 as part of an estate sale, I jumped on it.

Are there any potential pitfalls I should be aware of, or is there anything
I should be concerned about when assembling a 15-year old kit? All the
boxes have 2002 purchase dates noted on them. The K2 is SN 3172, so I know
it has the Rev "B" RF board.

Thanks & 73,

While they have it, you may also want to consider adding the KXV3B to get the second preamp for 17-6 meters.

Joe,

Thank you for passing along the serial number - that helps a lot with 
the K2 level.

Any K2 above SN 3000 is up to date with all upgrades (including the IF 
crystals) - with one exception, the K2 Keying Waveshape Mod which was 
introduced at SN 4660.  That mod kit is no longer available as a package 
from Elecraft, but I can send you the instructions and parts to order 
(send private email).  That mod is important for eliminating keyclicks 
that become obvious when an amplifier (such as the KPA100) is added to 
the K2.

If the KSB2 kit is included, you may want to order the SSBCAPKT to 
increase the OP1 filter bandwidth to the current 2.4kHz.

Check the firmware level, you may want to upgrade it to the current 
2.04r level - order FWK2MCIO from Elecraft.

For the KPA100, order the KPA100UPKT and KPA100SHLDKT.
The KAT100 has had no changes since day 1.

If you do all that, you will end up with a K2 that is current with those 
being shipped today.

Work carefully, and if you are unsure of what a good solder connection 
looks like, download the Soldering Tutorial from the Elecraft website. 
Most builders mistakes are from faulty solder connections and improperly 
stripped and tinned toroid leads.

Follow the instructions as written - they are correct.  If you do not 
understand a step, ask here and you will likely get an answer.

You may want to download the current manual (and errata sheets) and 
build from that.  For the base K2, the manual you have is similar, but 
some things have changed.

If you order the KPA100UPKT, definitely build from the latest KPA100 
manual (you will have some parts left over).

When winding toroids, be aware that a straight wire through the center 
of the core is 1 turn - a full wrap around the core is two turns.
If you are not up to winding your own toroids, you can order the 
pre-wound toroids from "The Toroid Guy".

What changes were made to FW Version 1.54 for the KPA500?? The notes 
only go to version 1.52.? Or is this just a typo causing the utility to 
show it as 1.54 when it is actually 1.52?

I am thinking about upgrading to a K3S for no particular reason since 
the K3 is as close to perfect as one could want.  I wonder what the 
interest might be in my K3/100.  It is a prestige serial number 101, 
ordered sight unseen the day the rig was announced. It was back to the 
mother ship in 2013 for a full upgrade to present specs.  The rig is in 
excellent condition, no smoke, no dings, no issues.  Used every day and 
got me on Honor Roll. You're next.

Includes:
sub receiver
antenna tuner
KXV3 transverter interface with output for a panadapter and RX antenna
Power cable
Kenwood handheld microphone
Fred Cady and Elecraft Manuals

I am looking for around $2,000.    What say you?

I updated the KPA500 to 1.54 and went to o=Operate on the amp.
The K3 displayed "Operate", but the K3 did not change the power to low drive power. I do doubt if it had anything to do with the update.
Then I tried to set the power levels switching from Standby to Operate and back. Still no joy.
Then I restored the K3 to an earlier configuration and all is well. Now the power switches from low power on Operate to high power on Standby.
Is there some menu setting that can select whether that works or not?
I could not find one.
What could have happened to the K3 to keep that from working as advertised?

V1.54 corrects a bug introduced in V1.52 affecting the Power Adjustment feature. This feature allows you to calibrate the measured power against a calibrated good power meter.

If you installed the V1.52 beta it is highly advised that you update to V1.54 as it becomes available.

V1.52 corrected a very rare issue with the amplifier changing bands unexpectedly when operating in SSB mode. We want our products to be as good as they can
possibly be, thus we addressed this issue.

V.154 is now being phased in as the production version for shipping KPA500s.

The KPA500 utility showed 1.54 available when I clicked "Copy New Files 
from Elecraft."? The firmware page on the website still shows 1.47 as 
the latest production release.? Apparently I caught the update with the 
utility before they had a chance to update the web page.

I believe PWR SET in the CONFIG menu has to be set to 'Per band' for it 
to save two power settings - one for barefoot, and one for amp 
operation.? It is on page 53 of the K3 Owners Manual.

Message-ID: <CA+33ts7-+2JrWwiFY12=jTH5zo5zkH9e4LDuvOLWNxmEhyYF=A@mail.gmail.com>

I run my KPA500 remotely... very remotely

There are times when I am running at full power in a carrier mode that I
turn the fan on high manually.  Which is pretty funny when it is blowing
-10C air through it.

Then, when I am done, I turn it down.

But.. there are times when I actually get to the remote station and find
that that fan is still running at high speed even though all the remote
controls show it at low speed.

Has anyone else notices this?

The elves down in Watsonville have been incredibly busy the last few weeks. Most things got done, but a few are still on the ?to do? list. Updating the KPA500 firmware web page is one of those.
Obviously the latest version (1.54) made it to the web site for the KPA Utility to find, and I can verify that V1.54 is indeed a released version.

Thanks for reminding me about this. I had been watching the firmware web page and forgotten about the KPA Utilitiy?s ability to perform magic.

73!

Message-ID: <001101d37d03$fbd6ab40$f38401c0$@snet.net>

Problem of reported "low audio" on 10 meter FM solved!  (actually, there was
no problem)

 

Thanks to Don for telling me how to find the FM DEVIATION adjustment (under
the TECH MODE sub menu).  Once getting there, it was obvious that I didn't
want to change the deviation setting from its default 5.0 Khz.

 

I made a comparison test using my IC-7000 vs. the KX-2, both on 10 m FM
simplex at about 5 watts into a dummy load, while using a third FM receiver
to record the results.  

 

The KX-2 audio was more than adequate and I found using an MH3 mic gain
setting of 40 +/- was about best.  I may be biased; but the KX-2 sounded
smoother to me than the IC-7K!

Yes, I think I've seen something like that but wasn't able to characterize
it succinctly. I often set the fan on 1 or 2 when operating remotely. If I
power cycle the amp, it seems to come up with KPA500 Remote saying the fan
is on 0 when in fact it's still on 1 or 2 ... I think. Two possibilities:

   1. It might be best to reset the fan to zero when it powers up. Then the
   KPA500 Remote display would be correct, albeit only by coincidence. I don't
   know how many people prefer the fan setting to persist through power
   cycles, though.
   2. It might be best for KPA500 Remote to read the current fan setting at
   power up and display it correctly intentionally. I don't know if that
   setting is readable, though.

than the K3S and only 1 dB better than the IC-7300. I guess no one is 
using these rigs in high-signal conditions.

Bragging rights for the K3, KX3 and K3S owners.

Rick;

I am suspecting that the remote software isn?t checking for fan control properly.

The ^FC; command can both set and read the fan setting; the remote software
should certainly be reading it. There is a command that has not yet been added
to the KPA500 Programmer?s document to report fan speed. It is:
^FS;
The response will be:
^FSn;
where n is an integer from 0 to 6 indicating the current fan speed.

The Fan Control setting is saved in EEPROM and is sticky. It will be preserved
across power cycles.

And now I will spend some of my holidays updating the KPA programmer?s reference. 
It is a far better experience than going to the mall?

73!

Jack, W6FB

:-)? By all means stay far away from shopping areas for the next few weeks. They're worse after Christmas than before!

I think you're right about KPA500 Remote. Although I'm not at my KPA500 QTH today, I just powered it up using KPA500 Remote, set fan speed to 2, power cycled it the amp, and Remote came back showing fan speed 0. Please note the issue to whomever is maintaining KPA500 Remote these days.

Have a happy,

/Rick

My guess is that the "Front end selectivity" is not an "A tracking
preselector" but rather a "B Band Pass" and that the bandpass is
wider that that of the 7300 in order to support the "dual RX"
capability of the 7610.  It's either that or the design/hardware
has some significant bugs.

The other explanation would be simply that direct sampling SDR has a
far wider measurement variability than traditional receiver topology.
Note the 12 dB difference in IMDDR3 between Flex 6700 on 9/29/14 and
the Flex 6700 measured on 3/17/17.

A little victory here for me. Finally downloaded a new driver for my
Startech USB3 video capture box and also a new version of VLC media player
(free, open source, donation would be nice...)

After installing the driver I fired up VLC, opened the media menu, opened
capture device and selected DirectShow.

P3 SVGA came up instantly in a resizable window nice and clean. I'm just
using a NUC i5, Win10 and it's consuming about 5% CPU time which is very
reasonable.

For extra points I modified the properties of the desktop shortcut for VLC
putting "dshow://" after the program invocation which was already in
quotes. Include the quotes in the dshow portion.

Clicking on the link now goes directly to showing the SVGA stream.

I'll do some further testing to see if anything weird crops up when running
N1MM+ and sending CW, etc., but looks good so far!

woo hoo!!

How is it possible to compare the dynamic range of a direct conversion radio with a superhet, where a mode-specific filter can be placed at the first mixer, with the expectation that direct conversion would give similar dynamic range as a superhet?

I haven't heard yet a technical way to explain this, especially given how Wes Hayward defined how to measure receiver dynamic range many years ago.

Jim, you should try the DirectShow feed with Win4K3Suite, I don't have a
P3, but I know it supports a couple of different VGA capture devices and
I'm pretty sure it's using a DirectShow feed.  There is a trial of
Win4K3Suite, you should give it a try.  Then you have an integrated setup
for your K3 and you won't need to use VLC.  It's worth a try, maybe Tom the
author of Win4K3Suite will chime in.

Jim, you should try the DirectShow feed with Win4K3Suite, I don't have a P3, but I know it supports a couple of different VGA capture devices and I'm pretty sure it's using a DirectShow feed.  There is a trial of Win4K3Suite, you should give it a try.  Then you have an integrated setup for your K3 and you won't need to use VLC.  It's worth a try, maybe Tom the author of Win4K3Suite will chime in.

Al -

The published specs indicate "diversity" (not just dual watch). If there is
a difference between "diversity" and "full diversity" it is not something
of which I am aware.

I have completed the K3S kit assembly but had questions about the receive
sensitivity. On the advice of Gary, AB7MY at Elecraft Support (Thank you) I
have went through the filter configuration again via the K3 Utility and
improved things to the point that I now hear AM broadcast stations but few
hams down in the mud (band condx? and poor single #14 insulated long wire
antenna 6' in air-my son is to help me get OCFDP up when we can (have 6
element tri-band yagi that needs rebuilt on saw horses :-)). The only
signal generator I have is an antenna analyzer with a -10dbm output. After
some research to use the analyzer to supply a low level signal to the K3S I
have come up with these values for a Pi attenuator circuit and would like
to have someone check my results and give advice:
-10dbm analyzer fixed output or 71 millivolt rms attenuated to 50
microvolts rms would be, I believe, a 63db attenuation. For a Pi attenuator
the resistor values would be two R1=50 ohm resistors (signal to gnd), for
the one R2=35.3 kohm resistor (in series with the signal between the two R2
resistors). Probably just use two 47 ohm and one 33 kohm. I don't intend to
do ANY calibrations with this device, just a way to see how the K3S is
functioning and that my thinking is in the ball park.

Thank you and 73,

You're right, it is misleading to compare third-order intermodulation 
distortion dynamic range (IMD3) specs of a direct-sampling receiver and 
a superhet.

With a superhet, the distortion tends to increase linearly with signal 
level, 3 dB per dB for third-order products.  So you can measure IMD3 
using different techniques and signal levels and get approximately the 
same answer.

With direct-sampling receivers you can get almost any result you want 
simply by slightly changing the test parameters.  Even measuring the 
same receiver using supposedly the same technique, the results are often 
inconsistent.

In my opinion, the best apples-to-apples comparison of direct-sampling 
and superhet receivers is blocking dynamic range (BDR).  It is a simple 
measurement of the ratio between the strongest signal the receiver can 
handle and the weakest signal it can hear.

BDR tends to be limited by phase noise when the interfering signal is 
close to the desired signal.  This is not a measurement artifact but 
reflects actual on-the-air performance.  Direct-sampling receivers tend 
to have an advantage close-in, although a superhet can also do well if 
the synthesizer is carefully designed (for example the K3s :=)

Thanks, Dave. I used that extra word ?full? for no reason. Thanks for confirming that it does diversity. I had heard that the VFOs weren?t actually phase-locked. Glad to hear they are. 

Merry Christmas,

Yes, those are the correct resistor values for a 63 dB attenuator, but 
as a practical matter, you may find that you have trouble getting that 
much attenuation in a single stage due to the stray capacitance of the 
series resistor.  It might be better to break the attenuator up into two 
sections of about half the attenuation.

As far as resistor choice, all resistors have some stray inductance and 
capacitance.  In my experience, "non-inductive" resistors like carbon 
film or metal film tend to have best broad-band performance with values 
in the vicinity of 100-200 ohms (at least for through hole resistors). 
Higher values are limited by stray capacitance; lower values are limited 
by the stray inductance.

So if you need a low resistance, two or more equal-value resistors in 
parallel may work better.  For a high resistance, several in series may 
give better results.

Alan,

Maybe this (low BDR) explains why the ?7610 provides such a huge amount of user-selectable attenuation. I think it?s on the order of 45 dB.

Hi All,
My KX2 seems to be both deaf and mute on 40m. 80m is alive and well as 
are other bands. The KX2 is pre loved (I hope) and is fitted with the 
atu and clock. Any suggestions on where to start. I tried moving the 
antenna plug but no difference.
When I press the atu button it displays 25-1? all through the tune. No 
RF comes out at any point. 40m is the band I wanted to use but thats a 
bust for now till it is fixed.

Be careful!  The IC-7610 lacks a second "Line Out" connection for the
sub-receiver.  That means that the user can not feed each receiver to
the left/right channels of the  soundcard and decode data modes on both
receivers at the same time ... think monitoring a DX station and
listening for callers in the (split) pile up at the same time, etc.

Subject: [Elecraft] The Icom touch screen??
Message-ID: <d453bcb2-35dd-9684-a665-b89b0505c941@w2blc.net>

My only experience with a touch screen is my iPhone - which I find to be 
very inaccurate, ineffective, and is most certainly addressed with many 
four letter word invectives. My hands are not large, I do not shake, I 
am a reasonable sketch artist, and was, at one time, a world class 
shooter. With that in mind, I have pretty much written the 7300 and 7610 
off as something I would not be happy with - due to the touch screen.

I control my K3 with a KPod and a Genovation keypad. Accurate and 
repeatable operation/control at all times.

OK - that is my take. I have not tried a 7300/7610 first hand. The only 
way I can do that is to purchase same and have it sent to me. So - any 
experienced comments out there? Am I wrong in my touch screen 
assumptions? Or, is the touch screen really the greatest thing since 
sliced bread?

Yes,

And while you can do SO2R with the dual antenna configuration, you can't
really do SO2R the way it should be as it doesn't handle OTRSP to handle
the audio switching.  At least, from what I have seen.  That can limit some
contesting features.

Jim,

The IF takeoff point in the K3 is right after the 8.215mHz mixer, so at 
that point, it has a very wide bandwidth.
The K3 filtering is after that IF takeoff point, so any filtering in the 
K3 will not affect that bandwidth.

I don't know how much wider than 200kHz the IF takeoff might be.
200kHz is a substantial portion of any band.

Tony,

The SWR of 25 tells me there is a problem with either your antenna or 
the ATU.  Try it into a dummy load (do an ATU TUNE into the dummy load 
first).

If you still get a high SWR with the dummy load, I would contact 
Elecraft support for assistance.

Hi all and Merry Christmas,

Well, the ham band specific HF filters are probably significantly narrower
than 2MHz, tailored to the actual width of the band in question. I don't
know if there is a way to tell the K3(S) to use a general coverage filter,
if installed, even if inside a ham band. That would circumvent the problem.

Hi Don, Seasons greeting to you.
The problem is only on 40m (7.0mhz) and I suspect band pass filters as 
nothing wrong with ANT and the same result into a dummy load. When I 
press the tune the display shows 0.0 jumps to 10.0 and straight back to 
0. I am suspecting a trip to the hospital is going to be called for.
I am not sure when the factory will be back from holidays but e message 
in the queue will be dealt with as and when. I am not in a desperate 
hurry so I guess we will work it out. They all deserve holidays.
Thanks for the pointers.

Joe - Receiver topology probably doesn?t have a lot to do with the variability in Bob? s measurements.  Note, for example, the similar difference in narrow spaced dynamic range, 10dB, between the  K2 measured on 10/03/04 and that measured on 2/27/04. - Duffey KK6MC

Hi Tony,

It's my understanding that Elecraft will be closed Monday and Tuesday for
the holiday

For your KX2 issue, did you also test into a dummy load on  60M?
The KX2 shares  the LPF on 40M and 60M  (page 14 in the schematics package)

Hi Howard,
Thanks for the info on the closed days
I hadnt tried the RX on 60m but just have and it seems to be similarly 
affected.
The TX on 60 also shows continuous 25.4 swr.
Sounds even more likely the band pass filter now is faulty.

Subject: [Elecraft] [OT] Heil ProSet K2 with Kenwood TH-D72a HT?
Message-ID: <1514235243726-0.post@n2.nabble.com>

My Heil ProSet K2 headset works great with my K3S, of course. I just got a
used kenwood TH-D72a HT for some satellite fun and wonder if the Heil
headset will work with the HT? The TH-D72a lists:
Microphone Impedance	2 k?
Audio Output (at 8 ?, 10 % distortion)	More than 300 mW (at 7.4 V)

But I don?t know the Heil specs or if I can get an adaptor. Any help
appreciated.

I could be wrong, but I thought they were low pass filters, not band 
pass.? I think each filter even covers more than one band if they are 
within an octave or something like that.

Somebody please correct me if I'm wrong.

Hi again,

Heavens no, they are definitely bandpass filters, tailored to each ham band.
I think I have seen a plot of their responses somewhere,  but can't remember
where. Each filter covers 2 bands with a relay to choose which one of the
two.

It might be worth taking a look at the bandpass filters, just to see if 
there's a broken inductor wire, or something else simple.? I've always 
been suspicious of those toroids supported only by their leads.? You 
could also just do some continuity tests, to make sure the relays are OK.

Unfortunately, the filters are on the main circuit board.? If you can't 
fix it yourself, you'll have to send the whole radio to Elecraft.

Yes, they are bandpass filters, to reject the image 16 MHz from the 
desired frequency, among other things.? There are, of course, also low 
pass filters, to reduce transmitted harmonics.

Bret,

The Proset K2 has an electret microphone, and needs a bias voltage applied.
So if your TH-D72 does not provide bias for the mic element it would not 
produce audio.

The Heil Proset is available in several models, it is important to state 
which one it is.  The Proset-K2 and the Proset-iC both have electret 
emic elements, while the others use dynamic microphone elements and do 
not need bias (should not have it).

Bottom line, I suspect your Proset-K2 will not work with the TH-D72a. 
If you want to check for certain, turn power on and measure the voltage 
between ground and the AF microphone pin.  If you find a positive 
voltage from 5 to 8 volts, the Proset-K2 will work with the proper 
adapter, but if the voltage is zero, that particular Proset will not work.

Don W3FPR

Back when I last owned a K3 (2009?), I had a piece of software that would,
among other things plot the SWR of the antenna attached to the radio. 

 

Now that I've picked up K3, I'd love to find the software in question. It's
not the current Elecraft K3 configuration program, the Win4K3Suite, or
N4PY's software packages. 

 

Is anyone familiar with the software I'm thinking about?

Eric,

I believe you're thinking about K3_EZ, which was written by W2BC, who is now
a SK.  I just uploaded three versions to the Files folder in the Elecraft_K3
Yahoo Group.  I think the last version had a bug in the TX audio settings,
but I'm not sure.

https://groups.yahoo.com/neo/groups/Elecraft_K3/files/K3_EZ/ 

The Zip files are each about 7MB.

Hi Scott
I had a look inside and under the atu but nothing looks out of place 
until a little smt device dropped out. It looks like a coil of some sort 
but I am not sure where it fell off and even if I did I now dont have 
the facilities to put is back with any dignity. So when the elves get 
back to work I will get an RMA number and box it up and send it off for 
them to remedy. Since its second hand it wont hurt for a once over.

It's as wide as the bandwidth of the BPF ahead of the 1st mixer.? There 
are several BPF's for the various bands and their BW no doubt varies, 
but is likely much larger than 200 KHz.

Wizkers:Radio can do an SWR scan with a K3, KX3, or KX2. It also works with some other rigs. Very handy bit of free, portable software.

Yes, by all means Tony should contact Elecraft service. They are staffed 
with very competent people, and have developed methods of supporting 
customers around the world.

Several years ago, I experienced excellent support from SDR Kits, a 
small UK company that builds the excellent VNWA Vector Network Analyzer 
designed by EE prof DG8SAQ. I fried the front end by absent-mindedly 
transmitting into one antenna while the VNWA was still connected to 
another one. They sent me enough of the schematic and parts layout 
around that stage that I was able to purchase the needed SMT parts and 
get a younger local ham with SMT experience and a good microscope setup 
on his bench to install them.? The parts I needed were inexpensive and 
easy to buy from the usual industrial electronics suppliers (like 
Farnell in the UK).

There's a good chance that Elecraft could do something similar. Perhaps 
Tony might start with a good photo of the board and the part that fell 
out, and send that via email.

I have only used Eneloop AA batteries on my kx3, so not sure if its just
them, but getting them out of the battery holder (on each end end) is
difficult.

So I cut a strip of coated paper from a catalog, and wrapped that around
the end of battery on the + end and now I can pull them out easily.
Here are some pix to illustrate.

Happy new year to all on this list!

I believe the batteries are really tight in the battery holder to provide a low resistance contact. I remember a post from Elecraft mentioning that they had to use a special battery holder to get that resistance down.

I used to see ribbon under batteries to help pop them out of a holder. I?m pretty sure my 1960?s Sony transistor radio had those.

Excellent tip, Mike!? It brought back memories of my kid's toys that had a small ribbon behind the cells that you could pull and the cells would come out easily.? So, I just looked at the toys all of my grandchildren got for Christmas, and NONE of them had that feature.? Looks like I will use your tip on a lot more than my KX3!

Shucks, our $1000 wireless professional microphones use the ribbon 
technique to assist in removing the battery/batteries. Works great until 
some apprentice audio tech forgets to put the ribbon UNDER the new 
battery and then says "hey, what's this hanging out of the case?"

Tony, 
Elecraft have a service agent - Carlo Bianconi - in Italy who does great
work. Shipping was very reasonable.  Several of the 6Gs DXpedition team sent
KPA500s over to him for a hardware upgrade and full checkout before our
first trip (TX6G).
I'd chat with Elecraft support first, but if they suggest sending the unit
to Carlo, from our experience it will be in good hands.

Folks I have had a KX3 for years and used it mostly on CW (ok.. 95%).
With my rotator cuff surgery, I am up most of the night and listen on 75SSB.

I see NR, and of course PBT I/II as well as the RX EQ.  It dawned on me that I have never adjusted any of them.
Of note is PBT I/II where I am not getting full advantage of the optional filter.

The background noise at my QTH seems to be mostly atmospheric and S-5.  Any preliminary set-up that I can follow?

There is no specific Scan Delay,
But the speed of scanning depends on the VFO rate.  See page 42 of the 
K3S manual.

For transmit settings, follow the ?Basic Voice-Mode Setup? on page 15 of the manual. I tried to do it by tweaking knobs and never got anywhere until, in desperation, I finally read the manual.

For more ?punch?, I collected advice on TX EQ and compression from this mailing list and compiled it into a blog post.

https://observer.wunderwood.org/2015/09/09/transmit-audio-and-compression-with-the-elecraft-kx3/

I run NR at a fairly low level, typically 4-5. NR works better on strong signals with the filters wide open. That gives the biggest difference between noise and signal, so the filter has an easier job. With faint signals, high settings of NR can decide that the signal is noise.

Subject: [Elecraft] [OT] Duplexer/Diplexer
Message-ID: <7C7690F6E8EE413CA67AEDF4BFFFD7EC@JRPC>

2 Radios, 2 Antennas, 1 Coax.

That pretty much says it all.  I currently have a KX3 and a 2-meter rig (but I?ll probably be outfitting the KX3 with 2m?s in the future) and I use a HamSticks for HF or a 1/4 wave GP for 2 meters.  Running another coax here is not a option (apartment) so I have been swapping radios/antennas.  Now I?m thinking of using two HF/VHF Duplexers (or Diplexer as they are also called) to join/split the RF.  For example using two of the MFJ-4916S, one port is 1.6-56mHz and the other is 140-540mHz.  Hf power output is limited to the KX3 (12w?) and VHF is currently the IC-2300H at 65w.  I understand that there will be insertion loss/isolation issues.  I have never pursued using splitters on a coax feed before and tho two simple A/B switches (manual or remote) would work better, I?d just like to keep things simple.

Hi David,
Have been contacted by Elecraft support and as you suggest they also 
recommend it goes to Italy for repair. Now all I have to do is wait for 
the RMA from Carlo. Support did also id the part and location for me? 
even with a photo of the location.

Great service as you would expect.73 de Tony G6GLP

You will need a duplexer on each ends of the coax. ? Preferably these 
should be identical. ?? One at the bottom end to combine the HF and VHF 
signals to one coax and then on the top end to split the HF and VHF 
signals to feed each respective antenna.?? Do be mindful that these 
units are? a bit fussy regarding operating in applications where the SWR 
may be high.?? Thus they really prefer installations where the impedance 
if near 50 ohms otherwise where the SWR is low, usually less than 1.5: 1 
or so.??? Also,? physical separation of the two antennas is also desirable.

Good luck with the project.? I do understand as I lived and operated 
from a condo in S. FL? for several years.

Dear all,

I am trying to understand if it is possible to get a kx2 decode cw tx 
for code practising purposes if using a straight key.
I get everything working nicely using the internal paddle but I cannot 
get it working with an external straight key connected to the 3.5mm key 
contact.

I do manage to get the monitoring side tone but I get no decoding.

Anyone knows if this soukld be possible and how?

Exactly right!? And MUCH more than "a bit fussy" -- these are passive 
networks, and ALL passive networks depend on both source and load 
impedances being right. Don't expect something like this to work right 
(or handle power) with non-resonant antennas.

Sorry, Bjorn, transmit text decode only works with the internal keyer. 

There is another way. You could build a simple crystal oscillator that puts out a weak signal somewhere in the KX2?s receive tuning range. Once you tune into that signal, the decoder could track your CW regardless of how you send it. I believe it will go down to about 8 WPM. You?ll need to experiment with the decoder?s RX THR setting.

Not the same.  A duplexer is used to permit simultaneous transmit and
receive functions in an application such as a repeater.  A diplexer is
used to combine the simultaneous output of two transmitters, such as the
visual and audio sections of an analog TV transmitter.

And as others have said - they are very fussy to set up and keep in
alignment.

Don, 

You asked: 

    Did you have the front panel board isolated from the other boards when 
    you made those resistance measurements? 
    If not, that is sufficient reason for the low resistances. 

    73, 
    Don W3FPR 

Yes, the Front Panel board was by apart from the rest of the radio when the measurements were taken. 

After further investigation, I noted that /BANK2 is shorted to ground.  On a hunch, I cut the CCW pin of R5 (the leftmost pin), thus isolating R5 from /BANK2.  Now, with R5 isolated, all of the problematic measurements taken before are spot on.  See the table below (from the K2 Owners Manual, Rev I, page 29): 

Test Point      Signal Name     Res. (to GND)   First Meas       Meas with R5 (CCW) cut 
U1 pin 1        IDAT                 25 - 35 k          8.84 k             29.3 k 
U1 pin 2        ICLK                 25 - 35 k          8.93 k             29.3 k 
U1 pin 3        /SYNC              40 - 60 k          28 k                48 k 
U1 pin 5        5A                   15 - 40 k          4.1 k               24.4 k 
U1 pin 12       2V                    9 - 11 k          6 k                  10 k 
J1 pin 15       VPOTS             10 - 60 k          4.3 k               28 k 
J1 pin 16       ICLK                25 - 35 k          8.9 k               29.3 k 
J1 pin 17       IDAT                25 - 35 k          8.7 k              29.3 k 
J1 pin 18       5A                   15 - 40 k          4.1 k              24.4 k 

I still need to find the /BANK2 short to ground.  There is nothing obvious on the board here, though. 

Another odd behavior to note.  Prior to cutting R5 (CCW), and with the radio assembled and R5 set to midpoint, upon applying power, I got simply "ELE" on the display.  Then, turning R5 completely CW, the display changed to "Elecraft".  Turning R5 CCW a bit then back fully CW, I got "7100.0c".  Have no idea why this is happening. 

I tested all of the /BANK2 switches (S9 - S16) and they all appear to be working.  Orientation of D4, D5, and D6 are all correct. 

Would appreciate any further thoughts.

Dan,

Since /BANK2 is OK with R5 removed, check the orientation of diode D6. 
Make certain it is oriented correctly.

You will have to order a replacement R5 unless you cut it in a manner 
that will allow you to repair the cut.

Message-ID: <CA+03d8g330FTGihYUR65_2m1YVNBBJhYZ91qzEpDs_7Xh9DFig@mail.gmail.com>

Last week, I sought help on this reflector in relation to the ERR 12V
problem that my K3 had developed.

The several replies I received from three different continents all pointed
me the same way and Elecraft confirmed the diagnosis.

I ordered the parts on 22 December and they arrived in today's post late
morning. This afternoon, I undertook the necessary repairs involving
partial replacement of one of the KPA3 power connectors.

The progress was slightly impeded as I found that my Hako 808 desoldering
tool, which I had not used for several years, no longer worked. Thus I was
reduced to using my soldering iron and a small manual vacuum solder sucker.
I got there eventually !

The rig went back together without difficulty and has passed the initial
test into a dummy load with flying colours, maximum power being achieved on
all bands.

Tomorrow I will put it back into one of my operating positions.

Thanks to all who provided help and advice, to Elecraft with their super
fast response and to the US Postal Service and Australia Post who both
excelled over the Christmas period.

Message-ID: <f3db9bbf-ea9f-989c-3381-71b80c17c1f7@gmail.com>

I just picked up the K2 unbuilt kit SN # 2620 from an estate sale. 
(Makes a nice addition to my K1, K3,KPA500 station)

After looking at the Elecraft site it looks like I need the following to 
upgrade to Rev B:

K2Bcompkt (K2 Rev B Comp upgr kit), FWK2MCIO (K2 MCU, IOC Upgr.), 
E850138 (K2 Temp Comp PLL Upgr.) and the E740001 K2 Manual .

The kit has the K2, KNB2 Noise blanker, KAT2 internal tuner, KAF2 audio 
filter/RTC and the KBT2 internal battery.

I would like to add the KSB2 SSB option and the KIO2 Aux I/O RS-232 
interface.

What else would I need to add or upgrade to this kit?


Thanks!

Gordon - N1MGO

Gordon,

That should get you the new boards and all the additional parts to 
install.  It should also get you a serial number for the updated K2.

If you want 160 meter operation, get the K160RX, and if you want 60 
meter operation, get the K60XV and a new rear panel E100075SS.
Hint - if you order the K60XV kit and state that you have back level 
firmware, you should get the FWK2MCIO at no extra cost.

Do you have resonant antennas?  If not, you may want to add the KAT2 - 
the base K2 needs to work into a 50 ohm non-reactive load.

Don W3FPR

Please add my name to that list as a feature req for the KX3.
Channel hopping (scan)  pause = x seconds/off.
By comparison, the ft-817 uses 3/5/10 seconds as scan resume options + OFF.
The kx3 resumes fairly quick after it stops on a signal. I never used
scanning on HF but it comes in handy scanning repeaters on 2 mtrs.

Subject: [Elecraft] K3 RX Equalizer
Message-ID: <CAME0jBSDAexke3BtXgZKtrENEHva-Si=t-4RP4fqzQuOmB=3kg@mail.gmail.com>

I understand that the K3 has two separate equalizer settings for CW and
SSB.  I also understand it is not active in the Data modes.

However, there are four sources of audio output:

1) Internal Speaker
2) SPKRS (rear panel)
3) Phones (front panel)
4) Line Out (rear panel)

Does the equalizer operate for all four outputs?

Thanks,

The RX EQ highest octave can be adjusted down to the lowest level to get
rid of hiss. The best change to make is turn the RF gain to -10 or  -15 to
get rid of the noise. Turn off the preamp. Those changes will make for the
best listening experience.

Folks I have had a KX3 for years and used it mostly on CW (ok.. 95%).
With my rotator cuff surgery, I am up most of the night and listen on 75SSB.

I see NR, and of course PBT I/II as well as the RX EQ.  It dawned on me
that I have never adjusted any of them.
Of note is PBT I/II where I am not getting full advantage of the optional
filter.

The background noise at my QTH seems to be mostly atmospheric and S-5.  Any
preliminary set-up that I can follow?

This varies widely by band and QTH. In a reasonably quiet location, the 
preamp will let you hear a lot more weaker signals on the higher bands. 
At my QTH, the highest gain preamp setting is needed on 12, 10, and 6M. 
My preamp is usually off below 20M.

I've been using a bug exclusively for the last 3 years (homebrew left-hander). On a few occasions, I've had to use a paddle, say, when visiting a friend's shack or at a hamfest. It took me awhile to realize I was using the paddle exactly like I would a bug: automatic dits and manual dahs. I didn't realize it til the other person pointed it out.

Message-ID: <CA+6T3Fu05OT0=U1T2_YJk3zmQZw=Vbupn7XkbekuhtBvJ-Mm5Q@mail.gmail.com>

FWIW, I started back into CW at start of 2015, and agree getting on the air
is essential.  But, I have also found that if I use a code reader to read
out what I send with straight key or bug in particular, in addition to
getting on the air, it really helps with weighting and rhythm.  I find that
if I just send without paying attention to that, I have no idea what I am
sounding like, even if I try to listen.  Could be just me.  I use a reader
on my Android phone called Morse Code Agent - just put the phone near the
speaker and it reads out what I am trying to send - or does not read it out
if my weighting or rhytim is off.  Useful feedback, especially when you are
just getting into it, in order not to develop habits that can hurt later.
Or so it has seemed to me.  73, Jim Ewing N4TMM

The K3 filter is a little unusual in that the receiver equalizer is part 
of the DSP bandpass filter, not a different or subsequent filter.? This 
helps minimize latency.

As a result, the equalization is applied before the audio paths are 
separated, so it is on all receive paths.

In data modes, the equalizer is disabled (the filter coefficients are 
re-computed ignoring the equalizer settings).

That would suggest that using hi-cut is a better choice than RX EQ for cutting high frequency hiss. The ultimate rejection for hi-cut is greater than the max RX EQ cut, right?

Does the KX3 work the same way? I would assume so, but might as well ask.

Hi, Lyle.

Thanks for helping me understand the K3 even better ;)

I'm working on building a remote solution using remotehams.com software.  I
hope I can use my SignaLink USB as the TX/RX audio interface to the
server.  I can hear very nicely on the remote (same room still!), but the
transmit audio seems very low.  Basically I've set MIC SEL to LineIn, and
selected my SignaLink USB as the audio source for the server.  I'm still
experimenting with levels, etc, and that's what led to the question.

Best regards,

Chris

Ok - finished doing the Opposite Sideband Nulling. (Also made sure the plugs were seated properly.)

The signals still show on the PX3 display, but not as strongly.
I?ve checked it on all bands and each band has at least one of these signals, some have up to six showing (with span set to 50.)
The placement of the signals is not the the same from band to band, however no signal is less than 12khz from the center frequency. Again, tuning up or down within the band does not affect the displayed signal.

Any ideas?

Back when I and my buddies were learning CW we had to pass 5, then 13 wpm sending tests at the FCC to get our license. That provided reassurance that our fists were readable. The same was true for my commercial radiotelegraph license using a straight key at 20 wpm. 

 

But, IMX, the best decoders still require CW sent to far more exacting standards for clean decoding than are necessary for easy, readable copy by a human operator.

 

What I sometimes do to check my fist is to record myself sending practice using a smartphone, tablet, or whatever is handy placed near the speaker, then play it back later and see if it?s a fist I?d enjoy copying. Yes, I still practice from time to time. My goal is to send decent CW using a page from a telephone book (remember those? Hi!). My goal is to get through one full page of names, addresses and phone numbers without a flub. (It?s harder than it sounds.)

 

Also, after 65 years of pounding brass, I?ve never aspired to competitive, high-speed CW. It?s rare that I?m QSOing above 25 wpm and I keep my straight key hooked up for the occasional QSO at 10 wpm or less ? whatever the other station is comfortable with. 

 

If you want to work at very high speeds, it is probably necessary to have special training in the techniques involved such as hearing whole words instead of letters. In the military we had to copy 5-letter code groups at 100% accuracy. Since no real ?words? were involved, the emphasis was entirely on learning to automatically write down the exact letters being sent without trying to make sense of the message. That was also valuable in commercial traffic handling to avoid stumbling over numbers and foreign or other unfamiliar words.  I still copy letters even when puttering around in the shack copying CW ?in my head?, recognizing each word after the letters are sent.

FWIW, I started back into CW at start of 2015, and agree getting on the air is essential.  But, I have also found that if I use a code reader to read out what I send with straight key or bug in particular, in addition to getting on the air, it really helps with weighting and rhythm.  I find that if I just send without paying attention to that, I have no idea what I am sounding like, even if I try to listen.  Could be just me.  I use a reader on my Android phone called Morse Code Agent - just put the phone near the speaker and it reads out what I am trying to send - or does not read it out if my weighting or rhytim is off.

Amen, Jim. 

You?re doing it the right way.

Text decode should be used primarily for monitoring sending.  Far too many ops who copy well think they can also send well when in fact they are running words together, running characters together, putting spaces in the middle of words (because they can?t spell), and exhibiting choppiness because there is no consistency in either character formation, spacing, or speed (a space at 30 wpm is different than a space at 20 wpm).

Better, even, than text decoding is recording your sending one night and playing it back the next night.  You?ll find yourself muttering, ?I can?t be THAT bad, can I??  Yup, you are, and it is in that moment of revelation that you have taken the first step toward developing an excellent fist.

I used to encourage monitoring NTS nets as a way of learning what good (live) code sounds like.  But, sadly, many of the really good fists are now silent-keys and you hear much more of the above named sins (even among net control stations) than you should.

Keep at it, Jim!

Bjorn, 

theoretically, it would be possible.  However, our human ability to recognize patterns is remarkably good; and therefore our ?wetware? can hear things (such as straight key) without special effort, whereas the machine may see only gibberish.  In principle, machine learning could be applied to this task; but, to my knowledge, none has.

I?ve read that the Morse decoding integrated into the Elecraft firmware is very, very good; however, I would wager a Left Hand Milk Stout that it would fail to decode all but the most precise straight key sending

The smarter guys writing software for digital modes have finally learned 
what we learned in the world of pro audio at least 40 years ago -- 
filters introduce phase shift, and both our ears decoding speech and 
software decoding digital signals don't like the time smear that comes 
with it. In general, the steeper the amplitude response, the more phase 
shift occurs in the passband.

Current recommendations for RTTY decoding is 500 Hz bandwidth, and this 
is echoed by guys who regularly WIN major RTTY contests. Indeed, the 
double-hump RTTY filter built into firmware for K3/K3S/KX2/KX3 is no 
longer recommended. K1JT urges WSJT-X users to run the receiver IF wide 
open and let the software do the discrimination between signals. I set 
my K3 IF to its widest settings.

The same thing happens when narrow filters are used on CW in the 
presence of static -- the crashes ring the filters, defeating the 
purpose of reducing overall noise level. K3/K3S firmware has some 
specially shaped filters to minimize this effect. RTFM to learn about them.

Jeff,

Do you by chance have ATTN on the KX3 engaged? If so, turn it off, and turn
on the PREamp on the KX3. That should eliminate the peaks in the PX3 that
you are seeing.

Jim, Joan, Ray, Ron, Wayne,

Thanks a lot for broadening my perspectives on cw code practicing, 
including prompting me to learn some Tamarian language and find out what 
a Left Hand Milk Stout is.

I am currently somewhere between 13-15 wpm receiving but know little 
about what I sound like when transmitting, and I feel I should explore 
that a bit before going on the air.

I could try recording/playback but a more interactive way would be nice. 
And if there is a tool available, I might as well use it rather than 
reinventing the wheel.

However, Jim, I? cannot find an app called "Morse Code Agent" in the 
Google Play Store. Do you have a pointer? I have gone through some of 
the many Morse code apps in there but have not yet found anyone offering 
the functionality that you mention.

Anyway, I wish you all a Happy New Year 2018.

Message-ID: <CAKynJK=K0Zn0DApeEC234ByWt5yzE=Tb7yLUbyW74m9cxxXNsg@mail.gmail.com>

I'm helping my son, K4TOO do some antenna work.  The antenna is up and
tunes on all bands with the KX3 on QRP.  When we put the amp in line, the
amp ATU tunes all bands, except 160.  When we hit the ATU tune button on
160, there are no clicking sounds.  The SWR remains High and the power out
is low, I suppose because the SWR is high and the SWR protection is
shutting down the finals.

The Amp is a year old and has worked well until July.  It hasn't tuned 160
since then. What I am trying to say is I think it is a problem with the
amp, not the antenna.

I'm not sure how to proceed.  I'm away from all my tools, so I am somewhat
limited in troubleshooting options.

Anyone have any suggestions?  Thanks.

Dave, K4TO

The ATU requires a certain amount of power so it can compare one SWR with another.  If there isn?t enough power, the ATU waits for it.

However, Jim, I? cannot find an app called "Morse Code Agent" in the

---------------------------
Answer:
If you go to Play Store, enter search query "morse code decoder", the first
app on the list that
pops up on my phone, at least, is "Morse Encoder Decoder".   The logo
features red dits and dahs that
say MCA.  When you select it, you will find it's the Morse Code Agent I
am talking about.  If
you have trouble running it, get with me privately and I can help - pretty
intuitive in my
experience.  As you send, it reads out the characters on the screen.

I also like a similar app called "Morse Decoder" by Wolphi LLC.  It shows
up 6th on the list when I do the
"morse code decoder" query.  It's a bit less forgiving than Morse Code
Agent in decoding unless your sending is
closer to perfect, but it does tell you the speed in wpm as it decodes and
reads out the characters.  Again, happy to help
if you have trouble.  With this one, it's really important to put the phone
mic near the speaker from which the cw is
coming - which makes the screen a bit more difficult to read (at least to
my eyes) than Morse Encoder Decoder which
does not seem to need to be quite as close to the speaker.

Message-ID: <CAP6Pu4FKyGa-OyKUzOF1yTuAXHkz6LJNsGTPfTeiOJbOKFAr4A@mail.gmail.com>

For 160, I've got a noisy TX antenna, and a quiet RX antenna.  I sometimes
run them in diversity mode, with TX antenna connected to K3's ANT1 port,
and RX antenna connected to AUX port.

Diversity works fine.

But the P3 shows the IF from the noisy TX antenna - in which many weak
stations are obscured by noise.

Is there any configuration by which I can get P3 to show, instead, the
signals from the quiet RX antenna (connected to AUX input)?

Tnx,

Hello Bill,

It *seems* to me that the following would achieve your goal, but the
gazillion cables behind the radios at this wireless station discourages me
from attempting to pull the K3 out away from the wall far enough to
actually try it.

-- Disconnect your low-noise rx antenna from the K3 'AUX RF' input, and
connect it instead to the K3 RX ANT 'IN'.
-- Then, engage the "RX ANT" button on your K3. You will then be listening
to your low-noise rx antenna on the main receiver, and that is what will be
displayed on the P3.
-- Then, use a BNC-to-BNC jumper cable to connect the K3 RX ANT 'OUT' to
the K3 'AUX RF' input. That will let you listen to your noisy TX antenna on
the 2nd receiver, the output of which will not be displayed on the P3.

Subject: [Elecraft] Y-BOX New Years Day Sale + Announcing New Version for
 KAT500 / KPA500 / KPA1500 / SteppIR Owners
Message-ID: <CAOmNKGJT4AD5RKawRP=-ToxGzojmVaTNpFCxAugZ3FP_GAvvAQ@mail.gmail.com>

In honor of the New Year, all Y-BOX orders received before midnight Pacific
Time New Years Day (by 2018-01-02 08:00 UTC) will get $10 off each unit,
while supplies last.  This applies to the original model only, with all 15
pins of the K3 ACC connector wired in parallel to all five DE-15
connectors.  I only have about a dozen of these original units left, and
this will be the end of the production run.  However, a new version is
being developed (see below), and I'm starting a waiting list for that now.

(The Y-BOX is a 4-way passive splitter and breakout box for the 15-pin
Elecraft K3 and K3S ACC / AUX port.  See https://bit.ly/Y-BOX .)

The original Y-BOX requires a KPAK3AUX cable (P/N E850463) between the
Y-BOX and a KAT500, KPA500, or KPA1500.  This cable has one male and one
female (M/F) DE-15 connector, with no connection on five of the pins, as
required by the amp.  The original Elecraft cables were bulky monitor
cables that had five pins cut. That was much improved more recently.

The NEW Y-BOX will provide the same function as the Elecraft AUX cable.
ONE of the DE-15 connectors marked "AMP AUX" will have no connection on
those 5 pins.  This means you can use a stock $10 M/F DE-15 cable with all
15 lines wired (NOT a VGA cable) between the Y-BOX and a KAT500 or KPA500,
and you can also use the same cable between the KAT500 and the KPA500.  Of
course you may still use the $24.95 Elecraft AUX cables on any of the DE-15
connectors if you already have them.

*Attention SteppIR owners*:

The Elecraft manuals recommend using a "Key Line Interrupter" to open the
KEY OUT line in the AUX cable (pin 10).  Then the SteppIR SDA100 controller
with the Tuning relay option
<https://www.steppir.com/shop/horizontal-antennas/2-element-antenna-products/tuning-relay-for-sda-100-controller/>,
or the N8LP SteppIR Tuning Relay <http://www.telepostinc.com/STR.html> is
placed in between the K3's KEY OUT phono connector, and the KPA500 KEY IN
phono connector, opening the KEY line while the SteppIR is tuning, to
prevent high power from damaging the SteppIR.

The NEW Y-BOX will have a Key Line Interrupt jumper built-in, optionally
splitting the amp KEY line (pin 10 of the AUX cable) into two RCA
connectors labeled KEY IN and KEY OUT.  Then you can conveniently connect
your "normally closed" SteppIR Tuning Relay to those RCA jacks.  With this
arrangement, you just need ONE DE-15 cable between the Y-BOX and the KAT500
/ KPA500 / KPA1500, and ONE stereo phono cable from the tuning relay to the
Y-BOX.  You no longer need to connect RCA cables from K3 KEY OUT and AMP
KEY IN.

*Attention K3-REMOTE users (K3/0-Mini and K3/0*):

"But there's one more thing ..." -- Steve Jobs

The NEW Y-BOX with a $10 cable can do one more thing that the stock
Elecraft AUX cable cannot:  it provides an internal jumper connection to
the amplifier's Pin 8 (PWR ON), a pin which has no connection in the
Elecraft cable.  You can then use a simple K3 macro to power up the KPA500
or KPA1500 remotely.  No PC required, no relay required.   The macro is
described on Page 21 of the K3 Remote Owner's Manual
<http://www.elecraft.com/manual/K3%20Remote%20Owner's%20Manual%20%20Rev%20D.pdf>.
 It generates a pulse on DIGOUT1 (Pin 11) to power up the amp.  This will
not work with the stock Elecraft AUX cable, but works fine with a M/F DE-15
cable from the Y-BOX to the amp. if the internal jumper is connected.

To review, *order the original Y-BOX any time before midnight PT this
Monday* to receive the one-time $10 discount on each unit, while supplies
last, or indicate in the notes if you prefer to be put on the waiting list
for one of the *new* units with the dedicated connections for Elecraft
Remote, SteppIR, KAT500 / KPA500 / KPA1500.  M/F Amphenol DE-15 cables in
both 2.5 ft and 5 ft lengths are now available to order too, but these only
work with the new Y-BOX, or between KAT500 and KPA500.  Cables are not sold
separately unless you have previously purchased a Y-BOX from me.

Happy New Year to all!

Fine business, Bjorn ^_^

One my fav ways to elmer the Morse code as practiced is, in fact, to set folx around a table and pass the ?transmitting station? around the table and have a real roundtable QSO (albeit only acoustically)

You can use your KX2 as the code practice oscillator by turning VOX off (or even just dialing the power down to 0.0, although the finals will still draw some power even at zero final output).  You could just set the rig in the middle and then pass the key around.  I?ve used this method for decades

tnx fer the chat  es c u dn the log = 73 all  de KX2CW Joan  sk  . .

Make sure your power supply provides enough voltage and can handle the power draw (300 watts is probably a good number). This happened to me too when I accidentally adjusted the voltage of my PSU too low. I now have it at 13.6V.

I had a similar problem on the low bands. I did three things:  1- Replaced the stock power cord with ~4 ft of #10 twisted pair cable; 2- Turned up the no-load voltage on the Actron linear supply to 14.2 v which gives me better than 13.5v @ 100w key down on the K3 display and 3- reran the K3 Power Cal procedure with the K3 Utility. It's been fine ever since.  GL+HNY

Good Evening,

 ?? Christmas day was white and it remained so for a few days.? Then ice 
and back to rain.? Today was surprisingly sunny and the moon is shining 
brightly.? The coyotes are making a lot of noise as the pack moves 
past.? They enjoy the break in the cold and wet but I think the moon is 
effecting them too.? It had been pretty silent during the cold, it is 
nice to have the birds and beasts back again.

 ?? The sun has been spotless with flux slowing too.? Since the storms 
aren't creating much lightning the noise should be low. Maybe the quiet 
conditions will allow us to work the weakened signals.? We can test them 
tomorrow with our last nets of 2017.

Please join us tomorrow on:

 ?? 14050 kHz at 2300z Sunday (3 PM PST Sunday)
 ??? 7045 kHz at 0100z Monday (5 PM PST Sunday)

 ??? 73,

Happy New Year!

I run my power supply at 14.0 volts as measured at the supply. This is 
done to accommodate the ~0.25 - ~0.35 volt drop in the DC line between 
the supply and the radio when in transmit.

Hi Bob, 


Rather than estimating the loss in your power cord, your K3 has the 
capability to accurately measure and display the DC power voltage 
internal to your transceiver. 


Tap DISPLAY and rotate the VFO B dial to show the K3 power 
supply voltage when you're transmitting.

I am not sure which transceiver you have, but on my K3S I had to use much
larger cables than the factory supplied to obtain 13.5v min when
transmitting. What voltage do you have when transmitting?

I seem to have low output on 75 phone. The most power I can put out is 71
watts. I can turn the power knob to 100 watts, but it backs down to 71
immediately. This is into an antenna and a dummy load.

I just checked 160 same thing except I get 83 watts

All other bands seem OK

I looked on their website yesterday for the same thing and did not see any
mention of a sale. Perhaps Vibroplex does not do the sale.  Luckily the
filter slots of both of my K3S's are full. I did notice that they are now
selling microphones, is anyone in this list using them?

Hi,
Did I miss an announcement, or has Inrad discontinued the end of year 
filter sale they used to have?

I don't think anyone has mentioned it but CWGet is a program that I have
used for years and it will decode the sidetone of the rig when you practice
off air using any type of key. (Turn the Vox OFF).

Yes, I've done that.? However, since the radio draws a different amount 
of current at 100 watts CW into a 50 ohm dummy load depending on band, 
the IR drop in the DC? line will be slightly different from band to band.

Chris,

To set the levels for DATA modes on Elecraft transceivers, see my 
website www.w3fpr.com.  Go to the bottom of the left column and click 
the link.

Yes, the Elecraft transceivers are different than other radios - you 
must first set the audio level to produce 4 bars with the 5th bar 
flashing on the ALC meter.

Happy 2018, fellow Elecrafters!

This note shares nothing earth shattering, but something I find much 
more useful than expected.  Using python, a super simple programming 
language, I just wrote a small k3 library of commands do simple things 
like retrieve or set frequency, keyer speed, enter/leave no-Tx mode, and 
so on.  Maybe an hour or two of programming.  As you need more commands 
you simply tack on more to your code.  A sample run - whose source code 
any interested are welcome to - with comments is below.  But programmers 
can easily write their own in short order.  Wayne (et al.?) have made it 
a snap.

Bill,

The only way I know of is to dig into the SubRX and connect its IF 
output to the P3.  The buffer circuit is there, but is not brought out 
of the SubRX enclosure.

I don't know of an easy way to transfer the P3 input between the main 
and the SubRX, but myself, I would simply use a relay external to the K3 
and operate it manually when you want to make the switch.

Most rigs that run on DC are designed to be run at 13.8V. It's important 
to realize that IMD in many rigs, including the K3, increases with power 
output AND with reduced power supply voltage. K6XX is an EE at Elecraft 
who works in manufacturing -- that is, taking designs from the team, 
putting them into production, and preliminary testing for the FCC 
approval process. Bob, a serious contester, is my neighbor, and we are 
both members of the Northern California Contest Club (as is Eric Swartz).

Several years ago, Bob put together a technical talk for NCCC on IMD, to 
which I contributed some on-air measurements and observations on the 
contributions of audio to distortion and splatter. Bob's slides include 
lab measurements documenting the increased IMD resulting from operating 
at reduced power supply voltage and closer to rated output. BTW -- early 
K3 firmware permitted operation to 120W; that was reduced to 110W 
because IMD at the higher power level was judged excessive. The slides 
for that talk are at

http://k9yc.com/K6XXAmpTalk.pdf

I've since done my own measurements showing that CW bandwidth is 
considerably lower at the 30-60W levels needed to drive most power amps 
than at 100W. That data is at

http://k9yc.com/P3_Spectrum_Measurements.pdf

In my own shack, a pair of K3s (for SO2R) runs from a 100Ah 
float-charged LiFePO battery, so terminal voltage stays in the range of 
13-13.6V keydown. About two years ago, I switched to the LiFePO battery 
from a big lead acid battery, because terminal voltage under load was in 
the range of 12.3 - 11.8V.

I had a similar problem on the low bands. I did three things:  1- Replaced the stock power cord with ~4 ft of #10 twisted pair cable; 2- Turned up the no-load voltage on the Actron linear supply to 14.2 v which gives me better than 13.5v @ 100w key down on the K3 display and 3- reran the K3 Power Cal procedure with the K3 Utility. It's been fine ever since.  GL+HNY

400Hz is definitely my favorite CW and RTTY filter. I also use the 250Hz
roofing filter (switched in at 350Hz) when the QRM gets bad, what document
shows that this offers little improvement?

I use similar settings for CW, with both filters.? I haven't tried DSP 
bandwidth of 250 Hz with the 400 Hz crystal filter, but based on the 
filter characteristics, I don't think it would make much difference.? 
Also, the 250 Hz filter drifts around so much with temperature that it's 
hard to keep it centered properly.

Compare the responses here:

http://www.elecraft.com/K3/K3_filter_plots.htm

Anyhow, all I'm saying is that even for a pretty hard-core CW contester, 
I'm not sure the narrow filter is worth the investment.

Now, my previous rig, an FT-1000D, which is inferior to the K3 in almost 
every other way, actually has better skirt rejection on CW, but that's 
with cascaded crystal filters, both of either 500 or 250 Hz bandwidth.? 
I'm not sure that's because of an inherent limitation of the K3 DSP, or 
just the filter algorithm chosen (perhaps to limit latency?).

The actual passband of these two filters is more important than the
marketing name.  The "400 Hz" filter is about 435 Hz wide at the -6dB
points.  The "250 Hz" filter is about 380 Hz wide.  Look at the graphs on
the Elecraft website.

400Hz is definitely my favorite CW and RTTY filter. I also use the 250Hz
roofing filter (switched in at 350Hz) when the QRM gets bad, what document
shows that this offers little improvement?

I prefer the 500Hz filter over more narrow ones.  Less IMD on the RX signal.

There is a newer 200HZ filter with more poles and does a great job in 
contest situations,

I have a FT-1000D with a Inrad 125hz filter in 455khz cascaded with a 
250HZ in the wide IF,
and the 1000D cannot hold a candle to a K3 skirt selectivity,?? that is 
the one major reason
I bought the K3 after using one,? the difference in skirt selectivity 
was so apparent it was
not even a question,?? I had several ft-1000D and none of them were even 
close,
If your ears cant hear the difference try measuring it.
Plus the 1000D filters cause IMD up the wazoo,? and by the way I also 
had the Inrad roofing
filter in the 1000D,? so actually 3 cascaded.
