Re: [Elecraft] KX3 & Loop Antennas

[thelastdb]

All, 
I found it convenient to program the PF2 key to toggle the ATU/THRU function 
with one button push. I have the PF1 key programmed as DUAL WATCH during the 
winter months for Fox hunts and programmed as RX Preamp in summer for Field ops.

KX3 & Loop Antennas 
Hi Tom:

There is a menu setting for the ATU which lets you put it in BYPass.

The AlexLoop is tuned manually.   It’s pretty easy:  with your KX3 set to the 
operating band of choice, simply tune the tuning knob on the antenna until you 
hear a peak in background noise.  It’s very pronounced, so you won’t miss it.  
That gets you in the ballpark.  Then, put the KX3 into tune mode (I use one 
watt) and then touch up the AlexLoop’s tuning, while keeping an eye on the 
KX3’s SWR display.  Dip the tuning for minimum SWR, and you’re done.

If you have to QSY more than a few KHz, you’ll need to touch up the antenna’s 
tuning.  The AlexLoop is a great portable antenna, especially for rigs that do 
not have an in-built ATU.   With the AlexLoop, the loop =is= the tuner.

Yes. When you turn the K3 off with its power switch, it writes current 
conditions to its RAM. When you turn it back on, it loads those 
settings. When you drop power to the K3, that write doesn't happen, so 
it comes up with whatever was last saved.


There are folks at Elecraft who are VERY familiar with the ins and outs 
of remote operation in general and control of the K3 in particular. 
Whatever issues you're running in to, they've seen it before and can 
suggest good options. I heard one of them give a dynamite talk to the 
Saturday morning tech gathering of the Santa Cruz club a few months ago. 
Your best bet is to pick their brains on this issue.

[Elecraft] Win4K3Suite - Next release will support the SDRPlay as a panadapter

[tomb18]

Hi Just a note...the next release due in June will support the SDRPLAY dongle 
as a Panadapter. The SDRPLAY will offer a maximum spectral bandwidth of 1.8 
Mhz, unlike the 192 kHz displays of other Panadapters. In addition, there will 
be no need for a sound card with this device. Look for it later in June after I 
return from my annual fishing trip.Back on June 8th so support for  the next 
week will be closed.73 Tomva2fsq.com

Read the user manual. Elecraft recommends ALWAYS powering-off the radio 
while the power supply is still on, so various settings and 
configurations are properly saved.


There's no way to guess if anything else in this SDR could be 
bollixed-up if you kill the power while the radio is turned on.

Re: [Elecraft] K3 and Microham keyer II

[Joe Subich, W4TV]

Please read and study the microKEYER II Users Manual!

All PTT inputs (PTT port, 2nd PTT Port, WinKey PTT, Foot switch, mic
PTT, etc.) are in parallel (just like the K3).  The PTT Outputs are
selected on the PTT Tab in microHAM Router - with PTT1 being the PTT
connector on the mic cable and PTT2 being the PTT connected to the
back of the rig (ACC jack for the K3).

If you have a PTT1 LED on MK II, you must connect the mic plug
to the rig in order for it to actually key the rig.

If you want to use PTT2, you need to select PTT2 for FSK/DIGITAL
on the PTT tab in microHAM Router, the K3 must be in FSK, AFSK A
or DATA A mode, and microHAM Router must be able to "read" CAT
data (frequency and mode) from the rig.

BTW, I see that Airlink Express has made substantial changes since
the set-up example was written.  It looks like FSK works properly
now (even though there are still significant user interface issues)
- but I will need to update the example(s) to cover FSK at some point.

*Which PTT LED?*  There are two PTT LEDs on microKEYER II (PTT1 which

As documented in the microKEYER II Users Manual and the configuration
examples for several popular software packages, you should configure
your digital software to generate PTT by raising the RTS line on a
virtual serial port.  In addition, Router/MK II should generally be
configured to assert PTT2 when transmitting digital modes.

When one makes it personal



Dan,

My apology if you were offended. Perhaps you're new to Elecraft. Many of 
us began buying their radios when they only sold kits, and everyone 
built their own. Indeed, many of us OTs built Heathkits. Elecraft buyers 
were not buying appliances,we were accustomed to working on our radios, 
and many builders developed mods that were later adopted and sold by 
Elecraft. A major reason that Elecraft products are as good as they are 
is that the owners are engineers, and they don't let their egos get in 
the way of taking input from their customers. The K3 was the first 
Elecraft radio sold factory-built, and it seems to have attracted buyers 
with different expectations.


My post was intended to help you realize that Elecraft is a company that 
does that. But it takes time to do analyze the problem, do the design 
work, and put those changes into production. With their competitors, you 
MUST buy a whole new radio to get the upgrade. It took Yaesu three 
product cycles (about ten years) to fix the awful key clicks in their 
flagship radio, the FT1000MP. With Elecraft, you can often buy only the 
upgrade, or even simply download new firmware.

[Elecraft] KX3 And Loop Antennas

[Reed]

Hi Tom,

Yes, I have had good success with the Alex Loop on PSK-31 using 3 to 5 
watts out from a high rise condo while on vacation.  Bands I used was 20 
& 17 meters.  I have not had much luck on SSB or CW no matter what 
antenna I used because of too much steel, concrete & man made noise.  
The loop cuts out a lot of the noise, but PSK just seems to work so many 
more contacts than on phone or CW.


If your apartment has a lot of wood you might be able to do well on 
other modes, but little Alex Loop does work well.  MFJ also makes one, 
but you have to change the loop depending on which band you are on.  
Also have one of those too, but like the Alex Loop better for traveling.



73,

Reed  W4JZ

How do you handle sending serial numbers that change with each QSO? 
Those can't be programmed into a KX3 memory.


If you use the N1MM logger (or any contest logger), you can program all 
messages into function keys, then tap the ESC key to cancel any of them. 
Also, typing the first character of the other station's call sign also 
immediately interrupts the CQ; you don't even need to hit ESC.


N1MM's function keys automatically handle serial numbers.

I always put my CW contest messages into N1MM, not in the KX3.

Re: [Elecraft] Narrow Digital Modes ??

[JWAHAR BAMMI]

I've been successfully running JT-65, WSPR this weekend on my KX2 @ 2.6 Watts 
and monitoring the PA temp on the VFO B display. The ambient temp in the shack 
was about 21C, at the end of the WSPR Tx cycles the PA Temp gets up to about 
58C. (20m, 30m, 40m frequency does not seem to matter). Look for kc1ccr on 
WSPRnet.

Rant:  I want to go /p or /m QRP digital modes. I don't particularly mind 
hauling my phone/tablet/Macbook air around /p /m or /pm. Not a fan of CW, and I 
am definitely not gen-x.

PA Engineering/Howie make us a KX2 heatsink already!

This is very encouraging !
My friend Terry VE3EGA is awaiting delivery of his KX2
I think he will try using it onJT9
And let me know...

I am uncertain why the OP claims the KX2 is not usable on JT65. One of the
KX2 field testers operated the radio on that mode without issues and
reported the same in an eham review of the KX2.

In fact, we paid great attention to frequency stability in the KX2 design,
applying lessons learned from the KX3.

The KX2 Tx power is more limited than in the KX3. But JT65 is a weak
signal mode :-)

Re: [Elecraft] KX3 & Loop Antennas

[Ramon Tristani]

I have tried the MFJ 1788 MagLoop and the TW2010. Both are good choices. The 
Magloop is good for up to a bit more than 100 watts. The TW2010 is better made 
and easier to operate and will handle a full gallon. Both are portable but the 
TW2010 is light and rugged.

[Elecraft] KX3 & Loop Antennas

[TFJM via Elecraft]

Has anyone had much success using either an Alex Loop or Chameleon P Loop
antenna with their KX3? I have few antenna options in an apartment situation
and throwing a 25 foot long wire into a nearby tree has not worked for me.
Even tried loading up a 33 foot long aluminum balcony railing with no luck.

Thanks,

[Elecraft] Suggested KX3 "upgrade"

[Jim Rodenkirch]

Wayne/Eric: I do lots of "runs" during contests and after completing a CQ run
and waiting for the "next cycle" I find, often, when a station returns my
CQ, if I hit a dit key to cancel the "beacon mode," the calling station
stops sending (he heard my dit and 'pauses').

Could sumpin' be done, firmware wise, to let us hit the the key without
sending the dit or dah?

I'm reluctant to push the msg button just to stop the beacon...seems like
I'd be stressing that button and it's inconvenient to access those buttons
while"in the fray" of a contest.

Thoughts???

Try powered (amplified) speakers ... the Line Out may not have enough

Probably not.  I'd pull the Audio I/O board (jack board) and check
to see if L3 (RF choke in the Line Common) is open.

Don't worry Joe, the FT817 fanboys will just add 160m and 6m on top of 2m/70cm

I don't believe there is another QRP rig on the market that can compare feature

In any event the KX2 will be my portable field rig for the foreseeable future.

Sitting here in my shack I'm trying to visualize just how small the KX2

Hoping to get my new rig before Field Day...that will provide a good "shake-out

[Elecraft] Can't get KXPA100 to turn on when PX3 is attached after SOTA trip.

[Terry Brown]

I disconnected my PX3 and KX3 from my KXPA100 to take on a SOTA activation.
When I returned I connected everything as it was before, and when I try to
turn on the KXPA100 from the KX3 "PA Mode" to on, the amp will not turn on,
and after a few seconds the PA Mode goes to off.  I disconnect the PX3 from
the circuit and connect the KX3 to the KXPA100 directly and everything works
as normal.  I have checked the continuity of the connecting cables from the
PX3 and KX3 and there are no short or open circuits. 

 

I have triple checked my cable connections to make sure they are connected
properly and have pushed in on the plugs to make sure they are firmly
seated.   The PX3 is showing properly one every band, and appears to be
working normally.  The KX3 seems to be working fine as well, I just can't
turn on the KPXA100.

 

Any suggestions would be really helpful.  Thanks!

 

73's,

 

Terry, N7TB

[Elecraft] K3 and Microham keyer II

Thanks for the reply Joe,, I didn't explain very well.
I am trying to work with Airlink express,  I have com6 set on PTT2 on the 
router, (com6 shows on the router as open). PTT1 is none (no com port)

And com6 for RTS on Airlink setup.
Going to transmit a red triangle comes up on com6, but only PTT1  LED comes 
on.

Ideas please.
Thanks

*Which PTT LED?*  There are two PTT LEDs on microKEYER II (PTT1 which
is the mic PTT and PTT2 which is the ACC jack PTT) and one on the K3.

As documented in the microKEYER II Users Manual and the configuration
examples for several popular software packages, you should configure
your digital software to generate PTT by raising the RTS line on a
virtual serial port.  In addition, Router/MK II should generally be
configured to assert PTT2 when transmitting digital modes.

I have used the setup given in the Microham manual, so far no luck.

Re: [Elecraft] KX2 on JT65 & JT9 ??

[Edward R Cole]

I ran extensive frequency drift measurements on the KX3 in 2014, 
purchasing an aftermarket heat sink for my KX3.  After running the 
temperature compensation procedure I reported:


   I re-ran the JT65 testing sequences to measure frequency drift 
after temperature compensation was done.
   Initial sequence shows the most drift with a peak +13 Hz upwards 
drift in the first sequence. The remainder

   Showed under 10-Hz with the delta trending to +5 Hz in later sequences.

Testing was done on 50-MHz which would show the most drift; I did not 
check for HF drift which one would expect to be proportionally less.


http://www.kl7uw.com/KX3.htm

Data is displayed on some charts accessible by link from main page.

I also acquired the heat sink produced by Elecraft but have not tried 
it considering the one I previously purchased has much more thermal 
mass.  Drift before adding heat sink and performing Temp comp. was 
103-Hz accumulated over 20-min test of running key-down in CW for 
50-seconds followed by 70-seconds in Rx, repeating ten times.


I use a professional frequency counter usable to 26-GHz whose TCXO 
appears stabile against a Rubidium reference.


I have not run the KX3 on JT65 very much (a little on 6m a couple 
years ago); haven't built IQ interface.  I have a K3 with EXREF 
running 2m-eme and 23cm-eme with transverters so the KX3 gets used 
for other kinds of use.  I have the 2M board installed.  Haven't 
checked drift on 2m with it.


Reading the mail to see what will be reported for the KX2.

That's your problem, not Elecraft's. The KX3 was specifically designed 
as a backpacking radio that could also do other things. AFAIK, neither 
Wayne nor Eric is a JT65 op or a VHF op, so they didn't think of the 
thermal issue until users brought it up. When they did, Elecraft 
developed the temperature compensation as a solution and also improved 
the heat sink. I did both to my KX3. It took about three hours, half of 
which was reading the instructions and cooling the radio for the second 
part of the procedure.


Reading ARRL Lab test reports clearly shows that Your "trusty old FT817" 
isn't one-tenth the radio that the KX3 is. The KX3 is FAR cleaner on TX 
and FAR superior on RX. But the KX3 is fundamentally an HF + 6M radio, 
not a 2M radio. A few weeks ago, we used a KX3 with the KXPA100 and PX3 
for a very successful mobile run in the 7th Area QSO Party.  Slide #8 in 
k9yc.com/7QP.pdf shows the setup that W6GJB put together. W6GJB drove 
while W6JTI operated, riding shotgun. The KXPA100 is on the floor of the

Re: [Elecraft] KX2 on JT65 & JT9 ??

[Walter Underwood]

Elecraft does not do the extended temperature comp because it would add too 
much to the price of the radio for a feature that only a few people need.

I’m surprised when people buy a KX3, then are upset that it performs to its 
specs instead of performing much better than specified. Both the FT-817 and the 
KX3 are 1 ppm frequency stability, though the FT-817 is only specified for that 
at 25º C after a 1 hour warmup. The KX3 specs are for 0-50º C.

Re: [Elecraft] New KX2

[Jim Rodenkirch]

Perhaps you meant to emphasize there's no " as small a rig on the market as
the KX2," Joe

I own a KX3 and expect it has more "features" than the KX2 and it's nearly
"as portable" as the KX2looking at a K3S ad believe it has more features
as well..agree?

Jim R.

[Elecraft] New KX2

[Joe W2KJ]

Howdy Fellow Elecrafters:

As I anxiously wait for my KX2 to arrive I'd like to congratulate Wayne and 
Eric for hitting this one out of the ball park.

I don't believe there is another QRP rig on the market that can compare feature 
for feature with the new KX2.

In any event the KX2 will be my portable field rig for the foreseeable future.

Sitting here in my shack I'm trying to visualize just how small the KX2 
is..hard to believe!!

Hoping to get my new rig before Field Day...that will provide a good "shake-out 
for the little rig.

Things sure have changed since I was a Novice back in '62 (grin)DX20 and 
NC190...what changes in technology we have seen in the past 54 years.

I'd like to be around for another 54 to see the future tech...but I don't think 
that is gonna happen (grin).

73, Joe W2KJ
I QRP, therefore I am

Re: [Elecraft] KX2 on JT65 & JT9 ??

[Jim Rodenkirch]

Wayne/et al:

I run JT9 and JT65 with my KX3 often on 160 and 80...I had the temperature
compensation performed at the factory when I purchased the rig and I utilize 
a cooling fan when running the JT modes or running a freq during a contest;
I loaded Dimension 4 s/w for extra time stability. No heat drift problems
here AND I didn't have to get ripped off by those 3rd party folks who market
those grossly over-priced replacement heat sync "kits."  

With what serial # did you start using the new that rev E board?

Will it be available for swapout by the fanatical few that need the latest
and greatest?

Tnx, in advance, for your reply.  71.5/72 de Jim Rodenkirch K9JWV

[Elecraft] KRC2 For Sale

[Dick via Elecraft]

I have a KRC2 band decoder and control kit for sale; asking $80 plus shipping 
(USA).
Am selling the KRC2 because I have 12 mono band antennas (6M - 160M plus 75M 
NVIS) and the KRC2 will only control 10 (10M - 160M).  Doing a bit of research 
(actually blind luck when perusing the Array Solutions web site) I found their 
Bandmaster III will control 12 antennas, and I picked one up at the Array 
Solutions booth in Dayton last week.
Though the KRC2 will work with several other manufacture's radios, I have only 
used it with a K3 (and now a K3S).  I have never had any problems or issues 
with it; I am the original owner, and it has always been in a smoke free 
environment.
For the K3/K3S (and I think all the Elecraft radios), control is best asserted 
by using the AuxBus; this requires one wire from the KRC2 connected to pin 2 on 
the AuxIO connector on the K3/K3S.
If interested, please fire off an email to me at either richarddw1...@yahoo.com 
or k8...@yahoo.com;  or feel free to call me on the land line (am an ARRL DXCC 
card checker, and my phone number can be found on the ARRL webpage).
Dick, K8ZTT

Re: [Elecraft] KX2 on JT65 & JT9 ??

Can't agree more with what you say about the KX3 !
The KX3 is a superb piece of engineering 
In my circumstances as apartment dweller with very limited antenna options - 
WSJT modes allow me to still operate and make QSO's -  thanks Joe Taylor!
In other circumstances there wouldn't be an issue
I envy your EME escapades!
Enjoy!

Re: [Elecraft] K3 and Microham keyer II

[Joe Subich, W4TV]

Using Airlink Express (or any other digital program) I can get the
PTT LED on the Microham to come on but it doesnt bring the k3 into
tx.


*Which PTT LED?*  There are two PTT LEDs on microKEYER II (PTT1 which
is the mic PTT and PTT2 which is the ACC jack PTT) and one on the K3.

As documented in the microKEYER II Users Manual and the configuration
examples for several popular software packages, you should configure
your digital software to generate PTT by raising the RTS line on a
virtual serial port.  In addition, Router/MK II should generally be
configured to assert PTT2 when transmitting digital modes.

I have plugged the microham into the ACC socket, to try to get the K3 to

I have used the setup given in the Microham manual, so far no luck.
Ideas please as to what I am missing.

Re: [Elecraft] KX2 on JT65 & JT9 ??

[David Anderson via Elecraft]

Fair enough, I am very happy with my KX3, a third party heatsink made it work 
for me on digital modes at the power I need. I mainly use it on 144 MHz 
currently with an external transverter. I actually enjoyed doing the 
temperature compensation procedure, it was fun.

The 817 is a nice all in one rugged box, however you can't compare the 
ergonomics or receive performance with the KX3.

Compromises have been made in the KX3 to make it small as a trail radio, a much 
bigger heatsink would not have been appreciated by hikers. They did upgrade the 
heatsink (a bit) in later models however. The KX2 uses the si5351 instead of 
the si570 synth, so in theory could use an external high stability reference. 

I prefer some of the features in the KX3 that the KX2 doesn't have, and like 
the larger size, AM FM, 50 MHz, PX3 option, internal 4m transverter option. So 
for me the choice remains the KX3. Good to have a choice though. The new 
internal battery pack is about the only thing in the KX2 that I wish the KX3 
had.

As Lyle mentions in his email for the KX2 - it would be helpful if someone

Hopefully resulting in increased sales!

 Thanks - just what I needed to know!
 Have you tried JT9 ?
 Perhaps some sort of heatsink/handles added to the case might help??

 I've actually just been sitting here running JT65 @ 10 watts when I got 
 your email, and it is doing pretty well. I had 3 back to back QSO's and on 
 the last transmission the PA Temp got up to 47C (~117F) which doesn't seem 
 too bad. As it cools off there is no drifting or slanting of signals on 
 the waterfall either. I think the 1 minute on/off duty cycle of JT65 is 
 very doable with the KX2, and WSPR might be pushing it. The other night 
 the sideplate got quite hot running WSPR at 5 watts.

Re: [Elecraft] KX2 on JT65 & JT9 ??

I thought at the price I paid for the KX3 I shouldn't have to do the 
compensation nor run the KX3 at such reduced power once compensated. My trusty 
old FT817 worked fine.
I also assumed Elecraft would address the issue with an updated KX3 -ie an 
'KX3s' at  some point.
So I sold it awaiting the 'upgrade' which turned out to be the KX2 !
Which is far more stable out of the box. 
I'm happy to now order a KX2!

[Elecraft] Audacity recorder with Xonar U& & NaP3

[Richard Ferch]

I am using a very similar combination (K3, LP-Pan/LP-Bridge/NaP3, Xonar U5)
and I have successfully recorded received audio with Audacity. You didn't
mention what sound card you were using for audio recording, but you cannot
use the same sound card for audio that NaP3 is using with the LP-Pan. I
have a separate sound card that I use for digital modes, fed from the K3's
Line Out jack, and that is the one I use for recording received audio in
non-digital modes. As I recall, once I had worked out which controls to use
in Audacity it worked FB.

After trying both, I ended up using QSOrder instead of Audacity, but that
was because of convenience issues, not the basic recording functionality.

73,
Rich VE3KI

Re: [Elecraft] KX2 on JT65 & JT9 ??

[David Anderson via Elecraft]

Dan ,

I am surprised that you couldn't get WSJT to go with your KX3 and had to sell 
it.

I am using my KX3 (note not a KX2) on WSJT on 144 MHz EME JT65b. I did however 
do the extended temperature VFO compensation first and that perhaps is a key 
requirement. The KX3 was actually more stable than my original 144 MHz 
transverter's TCXO, which I had to replace with a better TCXO to get the 
transmit drift to satisfactory levels.

[Elecraft] K3 and Microham keyer II

[Ross]

Advice please, I have the Microham working on receive, but I cannot get the 
transmission side going for digital modes.
Using Airlink Express (or any other digital program) I can get the PTT LED on 
the Microham to come on
but it doesnt bring the k3 into tx.
I have plugged the microham into the ACC socket, to try to get the K3 to 
transmit, but that doesn’t work.
I have used the setup given in the Microham manual, so far no luck.
Ideas please as to what I am missing.
Thanks
Roass
