Re: [Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

[tomb18]

Hi The kx3 or kx2 and kxpa100 will work just like a k3 and a kpa500. Make sure 
the kxpa100 is enabled in the kx3. Make sure the tuner is bypassed in both the 
kx3 and kxpa100, also make sure the power is lower than 30w out. Then you need 
the kat500 which will tune the antenna. In this combo, the kpa500 must be set 
to the band you wish to use.73 Tom

Ken,

If you are using TUNE (and not ATU TUNE), then there is no need for a 
macro.  Just go into the menu and set the KX3 TUN PWR entry as desired.

The ATU TUNE works with the KX3 alone or the KX3/KXPA100/KXAT100, but I 
don't know what happens if you use it with the KPA500.

At this point in the solar cycle, we are already seeing the MUF drop below both 
40 and 80 meters at night. Of course that is in the winter time,
and things should get a bit better as we get closer to summer. Still, for the 
near future the higher bands won’t be very effective. During the
(rather lengthy) low parts of the last cycle the MUF dropped below 80 meters 
for long periods of time at night, and even 20m wasn’t very
effective during the day.

I would consider some combination that includes 80 meters if you plan on 
operating at night. It is the higher band that would give me trouble
deciding, with 40, 30 and even 20m providing interesting possibilities. I kind 
of like K9YC’s suggestion of 30 meters where CW shines so well.

In any case, make a decision and enjoy it. Operating CW on the bands is always

Re: [Elecraft] What Two Bands would you pick for a K1?

[Harry Yingst via Elecraft]

Thank you
I've built a K2 in the past so I figured a K1 would be a fun rig to build (for 
me much of the fun is in building).
 40 is typically good here but I also see less on 30. The bright side is that I 
can always buy another filter board.

  Hi Harry - I had lost your original message - and I had a draft I was going 
to send to you - but couldnot find your original message . So here is a paste 
of  it  . FWIW- and I had concluded exactly your first line . 
The guy who just was talking about 80 and MUF has some thoughts 
dunno - here  in Phoenix - ther are quite a few W6 guys to chew the fat with 
inthe winter - but summers are  just no fun.. 

Guess I live in a 30 meter hole - Most times I  find nothing 
on 30 other than special event or DXpedition stations 
and the W0ERE 2 watt beacon . Once in a while a random rag chew .

Yes almost always some digital but we are talking CW I think . 

Then big pileups on a DX station and it all goes away when the DX quits .

Contrast that to 40 Cw and virtually always something to work. 

So I would suggest if you have a receiver - listen to 30 and 40 and 20 
at the times you will mostly operate and see whats best in your area. 

RE the 200 watts   On the P3 I have watched  guys turn
on their amps  - once I sent "turn off ur amp" and got a HI HI back .

Just saying ---

Re: [Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

[Don Wilhelm]

Ken,

If you are using TUNE (and not ATU TUNE), then there is no need for a 
macro.  Just go into the menu and set the KX3 TUN PWR entry as desired.


The ATU TUNE works with the KX3 alone or the KX3/KXPA100/KXAT100, but I 
don't know what happens if you use it with the KPA500.

I no longer have enough equipment to look for spurious frequencies but most of 
the time his KXPA100 would complete and the KAT500 would show very low SWR on 
the power meter I had along. The SWR on both my meter and the SWR line of the

consider that normal.

I am think of making a macro to turn the power down for tuning and if anyone 
know commands to turn the KX3 tuner off and the PA on in a macro please let me 
know and I will put it on one of his two PF keys.

Thanks for the help and I will let you know later how we come out.

Re: [Elecraft] What Two Bands would you pick for a K1?

[Cameron Francey]

For me I have a K1 with bands 20 and 40.  Both work well QRP at home on the 
main antennas and QRP portable with a simple wire antenna (T2 and random wire/ 
short counterpoise)

I really like 30m but there's more people on 40m so more chance of getting a 
reply there over 30.  I'd be torn between 30 and 40 if I was to chose again.
If I could only have one lower cost radio a K1 with 30/40 would be my choice.

I agree with Paul. I have a K1-4 (40-30-20-15) I bought in about 2005. Our
current position in the solar cycle says 20M for daytime and either 30 or 40
for nighttime. The choice between 30 and 40 would be personal. I've had
better luck on 30m with QRP than on 40m over the years. I have never made a
contact on 15 with the K1. It's just too spotty to depend on QRP there. When
it's open, it's really open, but it's the luck of the draw.

20M has always been my favorite band. These days weekday CW activity is kind
of sparse. I have almost NO luck at the 20M QRP freq, but I can nearly
always scare up a contact below 14.025 if I want.

Re: [Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

[Bill Johnson]

I have this setup.  It works well.  I would suggest a menu change to 5 watt
tuning with the KX3.  Do not tune everything at once.  Big error.  Do you
have a tuner in the KXPA100?  If so set on "Man" then tune the KX3 into the
KAT500.  This will stop what you are seeing.  Too many tuners going at once
will cause what you are seeing.  If that doesn't work, turn off the KX3
tuner and use only the Kat500.  Once tuned the rest should work.

Thank you to the three people that responded to this so far but each of you
accused me of having my friend run three tuners in a row. The KX3 turns it's
tuner off when it senses the KXPA100 is connected and turned on. There is a
setting in the MENU to turn off the tuner in the KXPA100 which we did and
have to keep watching as the equipment keeps wanting to turn it back on. The
problem we are having is tuning the KAT500. Hi SWRs are sent back to the
KXPA100 and it trips out. I was hoping there is someone out there that is
making this work. I have a K3S myself and a KAT500 and they work perfectly
together at 25 watts for tuning than the full 500 watts after it is tuned.
My friend does not have a K3S so we need to make the KX3 and KXPA100 work.

Thank you

I agree with Paul. I have a K1-4 (40-30-20-15) I bought in about 2005. Our
current position in the solar cycle says 20M for daytime and either 30 or 40
for nighttime. The choice between 30 and 40 would be personal. I've had
better luck on 30m with QRP than on 40m over the years. I have never made a
contact on 15 with the K1. It's just too spotty to depend on QRP there. When
it's open, it's really open, but it's the luck of the draw.

20M has always been my favorite band. These days weekday CW activity is kind
of sparse. I have almost NO luck at the 20M QRP freq, but I can nearly
always scare up a contact below 14.025 if I want.

Re: [Elecraft] Powered Speaker for KX1

[Jim Brown]

Yes, they are. Samsung made some 24-in displays that run on a nominal 
14VDC, and they run fine on 12V. Costco was selling them for a while, 
and as recently as two weeks ago, was selling a 24-in lower-resolution 
Samsung TV that runs on 14V. Like many things, you've gotta do a lot of 
looking around to find these things. :)  One place to look is the photos 
or specs on the Samsung website.

Re: [Elecraft] Is it just me?

[Jim Brown]

No question about that.  My 6M antenna is at the other end of 350 ft of 
LDF5-50, 0.9 dB loss. It's a SteppIR, so I also use it for legal limit 
on the HF bands. So my preamp is in the shack. If it was practical for 
me to install a dedicated 6M antenna at 120 ft (which is where the 
SteppIR is), I would. But it isn't practical.


It's important to realize that every engineering problem is different, 
most solutions are compromises, and which set of compromises are best 
for any given situation depend on many factors. In this case, real 
estate, the cost of another tower, somewhere to put another tower, the 
hard line that I can scrounge used at a good price, etc.  And yes, I'd 
love the extra 2-3 dB that a better 6M antenna would provide.

True... that applies to the K3 preamp as well so it can still be a net gain.

And if the feed line is 50' of 1 5/8 Heliax then it hardly matters.

Re: [Elecraft] What Two Bands would you pick for a K1?

[Curt]

I have a K1 built sometime ago with filter boards for all of the bands. The 
4-band is 15,20,30,40  A 2-band for 80,17; another for 12,10.  75% of the time 
mine is used on 20M, the balance split between 30 and 40.

IMHO one of the bands should be 20M.  As the sun declines toward minimum, 
anything shorter isn't likely to be too useful.  My pick for the second band 
would be 30M, because of the DX opportunities,

Re: [Elecraft] Is it just me?

[Ken Arck]

Well, I don't want this to devolve into an OT issue but it is well 
established that any feedline loss ahead of the receiver adds to the 
total noise figure of the system. (outside influences such as sky 
temperature, local noise sources, etc notwithstanding)


So if you place a preamp with a NF of .5 dB at the "rig end" of a 
feedline run that exhibits 3 dB of loss at the frequency involved, 
you now have an effective noise figure of 3.5 dB ahead of your 
receiver. Placing the preamp at the antenna has an obvious advantage 
of reducing that NF by 3 dB.

Not true. Yes, at the antenna end of the feedline is better, but the NF 
will apply to whatever signal the preamp sees. AND it strongly depends 
on how noisy our QTH is as compared to the circuit noise withing the 
radio/preamp. Preamps won't help much if you have a lot of RX noise.


A good rule of thumb is that you are not limited by circuit noise if the 
noise level increases by 10 dB when you connect the antenna to the 
radio/preamp.

Re: [Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

[Nr4c]

Sorry. But my solution to this problem was to use my K3S to teach my KAT500 all 
about my antenna first.  Now when I hook up the KX3 I don't have to tune the 
KAT500. It already knows the antenna. 


What do you see with a dummy load on KXAT100 with both ATUs By-Passed?  If not 
near 1:1, then start here and find out why. Once this checks, move dummy load 
to KAT500 output. Should also be 1:1 or nearly so.

Re: [Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

[Cady, Fred]

Although the KAT500 would like 20 watts to get a good tune it should be able to 
tune down to 10 watts (from an email long ago from Elecraft).  Maybe you can 
try turning the KXPA100 off and setting the KX3 to 10-15 watts (depending on 
the band) and then tune the KAT500.

Thank you to the three people that responded to this so far but each of you 
accused me of having my friend run three tuners in a row. The KX3 turns it's 
tuner off when it senses the KXPA100 is connected and turned on. There is a 
setting in the MENU to turn off the tuner in the KXPA100 which we did and have 
to keep watching as the equipment keeps wanting to turn it back on. The problem 
we are having is tuning the KAT500. Hi SWRs are sent back to the KXPA100 and it 
trips out. I was hoping there is someone out there that is making this work. I 
have a K3S myself and a KAT500 and they work perfectly together at 25 watts for 
tuning than the full 500 watts after it is tuned. My friend does not have a K3S 
so we need to make the KX3 and KXPA100 work.

Thank you

Re: [Elecraft] Is it just me?

[Nate Bargmann]

I thought of something later.  When you reply to the list does your
email client also send a private message to the person you're replying
to?  If so, that would explain why you're getting the message as your
client is sending two messages.  I presume the response message is to
enable a white list from real people to the recipient.

Re: [Elecraft] Advanced Receiver Research P50VDG 6M Preamp

If you really want an improvement, you should move the preamps to

(not to rain on your parage but you do realize that the .5 dB noise 
figure is essentially meaningless if the preamp is in your shack, right?)

Re: [Elecraft] Powered Speaker for KX1

[Tom]

Jim,
It seems like most of the larger displays are 19V.  At least mine are.  My
one smaller screen is 12V.  I have powered it from the station power.  Are
your monitors only 12V?  If not how are you powering them from your station
power

Re: [Elecraft] What Two Bands would you pick for a K1?

[Mike Morrow]

> What Two Bands would you pick for a K1?
> My first thoughts are 40 and 15,

There are only six bands that Elecraft supports with KFL1-2 band parts:  80m, 
40m, 30m, 20m, 17m, 15m.  Some have customized their own boards for other 
bands, notably 160m and 10m.

When I built a K1 in 2000, only two-band filter boardz were available.  I built 
two filter boards, one for 40m/20m, and one for 30m/15m.  I used those until 
the KFL1-4 four-band board for all four of those bands was available.  I 
converted the 40m/20m KFL1-2 to 80m/17m.

Without any doubt or question, if I were limited to one two-band board, 40m/20m 
would easily be my choice even as we head further into a long (perhaps very 
long) period of minimal solar activity.

It's not just you.  I never bother to click on the link.  The filter is

At the same time, I'm a strong advocate of replying to list messages 
through the list -- off-list answers never show in the archives and are 
never available to the list in general.

[Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

[Kenneth Christiansen]

Hi to the group

I have a friend with the following equipment.
KX3 with built in tuner.
KXPA100 with built in tuner.
KPA500
KAT500
50 ft of LMR400 coax
R9 vertical.
The KPA500 is not in the circuit at this time.
We try to tune the KPA500 using the station set for 20 watts and a hand key.
The KXPA100 often kicks out. The SWR of the KAT500 changes quite a bit over a 
tuning cycle and I think that is what is causing the trouble.

Is anyone else using this combination of equipment and can give us some guide 
lines on setting up each piece of equipment and a procedure to tune up the 
KAT500 without hurting the KXPA100?

Thanks to anyone that can help as this has turned into an expensive problem 
that has destroyed three pieces of equipment.

NO luck at the 20M QRP freq, but I can nearly always scare up a contact below

I do a lot of QRP, especially in DX contests. I wouldn't dream of 
hanging out on "a QRP frequency," and I never sign /QRP. If I get into a 
chat, I will say that I'm running 5W.


I'll reinforce the recommendation of 30M as a great band. The 200W power 
limit and no voice modes is a major advantage for those with limited 
stations or running QRP, antennas are of more reasonable size, and 
propagation is often quite good.

Yes, BUT -- they come with switch-mode power supplies, which will
add RF noise to your receiver.

Re: [Elecraft] What Two Bands would you pick for a K1?

[Eric J]

I agree with Paul. I have a K1-4 (40-30-20-15) I bought in about 2005. Our 
current position in the solar cycle says 20M for daytime and either 30 or 40 
for nighttime. The choice between 30 and 40 would be personal. I've had better 
luck on 30m with QRP than on 40m over the years. I have never made a contact on 
15 with the K1. It's just too spotty to depend on QRP there. When it's open, 
it's really open, but it's the luck of the draw.

20M has always been my favorite band. These days weekday CW activity is kind of 
sparse. I have almost NO luck at the 20M QRP freq, but I can nearly always 
scare up a contact below 14.025 if I want.

My first thoughts are 40 and 15, but I'm curious as to what others would pick.

Thank you.

Re: [Elecraft] Powered Speaker for KX1

[Mel Farrer via Elecraft]

While no longer available, the X-Mini UNO self-powered speaker is Lion powered 
and good for up to 18 hours of use.  It has lasted a whole weekend with the KX3 
and charged from my solar panel via USB port when not in use.  Oh well,
Mel, K6KBE

Re: [Elecraft] P3 TX Monitor

[John Lemay]

Don and Dave

Thanks for your replies. I've found the schematic for the W2 meter and
sensor and I can see now that there's a lot more electronics in the sensor
box than I thought. So rolling my own is not an option.

To answer "why" is easy ... I run more power on 2m and 70cms than the
sensor is rated, and would also like to include 23cms.

Thanks again

John,

There were some changes to the coupler done for it to be used for the TX
Monitor - capacitor changes as I recall.
If you want power and SWR reading accuracy, get a new RF Sensor.  OTOH, if
your main interest is in the waveshape display only, then the W2 directional
coupler may give you what you desire.

Re: [Elecraft] Audio Output Impedance of the KX3

[w7aqk]

Jim and All,

Thanks much for the explanation.  Makes a lot more sense now.  Not sure how 
I missed your past comments that covered that.


I also got several other responses which were most helpful, and I appreciate 
them as well.  It sure is nice to ask a question and get good answers!!  Hi.


Cheers!

Re: [Elecraft] Running WSPR on KX3 using a Mac

[Neil Zampella]

WSJT-X v1.7 (and 1.6) has WSPR built-in, if you have WSJT-X working then 
use it for WSPR mode, as K1JT has indicated that there will not be 
further work on the separate program.   All Elecraft transceivers 
are supported out of the box for rig control by v1.7.


WSJT-X v1.7 is in release, no longer Beta.

Yes, it's in v1.7, which I think might be in late beta. Yes, there's a 
Mac version. Download here.


http://physics.princeton.edu/pulsar/k1jt/wsjtx.html

v1.7 is a major upgrade -- more modes, more functionality, and 
improved decode performance in modes like JT65.

Re: [Elecraft] What Two Bands would you pick for a K1?

[Charlie T, K3ICH]

This is an impossible question to answer because there are SO many variables
that are based strictly on personal preferences.
Many more on physical parameters (location, antenna availability, etc.)  and
even some on time (of day or, as in solar cycle ). 

As a start, make a list of all the possibilities or variables you can think
of and you'll see that no one can make that decision for you.

Some things you'll just have to decide for yourself.

Re: [Elecraft] Running WSPR on KX3 using a Mac

[Peter Eijlander (PA0PJE)]

And WSJT-X supports I/Q receivers like the Funcube Dongle Pro+, at least 
in my Linux Mint 18.1 it does. At HF it tunes spot-on and decodes.

Tried 136 kHz, 474 kHz and several HF bands on a MiniWhip (WSPR)
Yes, 2200 meters on a piece of copper-clad 4 by 6 centimeters. 2E0ILY 
QRB 520 km. Amazing...

Re: [Elecraft] Running WSPR on KX3 using a Mac

[Edward R Cole]

I have recently installed WSJT-X and confirm it does:
JT4 -eme on microwave bands
JT9 -similar to JT4
JT65 -eme 50 thru 1296 MHz, three submodes: A/B/C
QRA64 -experimental eme mode to yielding up ot 3 dB advantage over JT65
ISCAT  - meteor scatter, aircraft scatter, other scatter prop
MSK144 - meteor scatter, aircraft scatter, other scatter prop
WSPR -propagation mapper
Echo -moon echo self-testing

Has versions for windows, linux, and Mac OSX
It has features designed for HF users in mind
Transceiver CAT control
Go to Basic Operating Tutorial (Section 6) of the on-line Users Guide:
www.physics.princeton.edu/pulsar/K1JT/wsjtx-doc/wasjtx-main-1.7.0.html

I have used JT65 since its introduction as JT44 in 2003 on 2m-eme
I also use it on 1296 and 50 MHz eme
just beginning use of MSK144 on 50.280 ms
Also have used WSPR on 495 KHz as WD2XSH/45 (currently QRT due to 
antenna failure).
I use my K3 with DEMI transverters for these modes.; have not yet 
built a computer I/F for my KX3-2M.
