[Elecraft] Transverters discontinued?

[Thorpe, Jeffrey]

I noticed in Fred Cady's "Assembling the KX3-Line Station" that he mentions the 
Elecraft XV222 and XV423 transverters. I hadn't paid attention to that until 
just getting my 2m option for my KX3. On the website I see that all that's 
available are manuals. Are these things history now?

[Elecraft] KX3 mic/spkr adapted to Kenwood K1 plug?

[Thorpe, Jeffrey]

I'm wanting to adapt my U94 PTT system that connects my mic/headset to a radio. 
This model uses the Kenwood K1 adapter. I was (initially) thinking that I would 
just need two patch cables as the KX3 has the mic and speaker sockets 
separated. However, looking at the diagrams of the TRS plug for the Kenwood mic 
and the TRRS for the KX3 it doesn't look like it will work without swapping 
wires. Has anybody seen such an adapter, or am I just mixed up? (My headset is 
only a mono version, not stereo, but that shouldn't have any impact on my 
problem.)

Re: [Elecraft] KX3 RX I/Q testing

[Thorpe, Jeffrey]

iSDR does require a USB soundcard with a stereo mic input, like the Griffin. 
The easiest way to check if you are utilizing the stereo mic function in iSDR 
is to check your iPad screen while running it and see if you are getting 22 or 
44 kHz. If it shows 22, you are only getting mono mic.

Re: [Elecraft] KX3 and RPi DRAWS hat?

Thanks for the info. I will likely wait a bit. While I would certainly like to 
use a Linux-based system, it seems that for the time being anyway, for portable 
digital ops I’m still better off using my Windows 8.1 tablet. (I REALLY hate

[Elecraft] KX3 and RPi DRAWS hat?

[Thorpe, Jeffrey]

I’ve been looking at one of Northwest Digital Radio’s DRAWS hats with my KX3. 
However, it uses 2 DIN-6 connectors. Has anybody tried one of these? Looks like 
it would require cobbling.

Re: [Elecraft] Swiss Army Knife

Geez - I lost my Swiss Army Knife (the teeny one) to TSA at Tucson too. What’s 
with that place. I’d had it over 30 years since before I got married. It as our 
30th anniversary, heading to Hawaii.
I have a new replacement now. Missing all the “character” the other had.

opener on the other?

Re: [Elecraft] 32 bit Elecraft Utility Apps

[Thorpe, Jeffrey]

Yes - you are correct. It didn’t occur to me when I installed it that it 
shouldn’t run due to the different architecture.
Turns out that the first thing I installed to the fresh installation of 
Raspbian was Exagear Desktop to test with a different application (a windows 
one.) I had thought that you had to tell ED to start the 686 emulator prior to 
running an x86 app, but it appears to automatically invoke when it detects the 
different architecture trying to load. So it started the emulator and runs KX3 
Util inside it.
It isn’t perfect though - for some reason it fails to connect to 
ftp.elecraft.com with a 127 error, even though the x86 machine can go to the 
internet. KX3 Util does connect to the KX3 and can do everything else though. 
Guess I’ll have to figure out how to correct that one problem.

I expect that a some time in the not-to-distant future they will release a 
64-bit version of Raspbian. It would be nice to have a native KX3 Util program 
compiled for the Arm. Raspberry Pis just get more popular for ham radio. It 
runs the FL suite, WSJT-X, and Chirp.

Re: [Elecraft] New PX3 - question on a signal that doesn't move

[Thorpe, Jeffrey]

Thanks everyone for the responses.
Also found a post from a few years back that talked about this too (from Don I 
think referencing Wayne). Puts my mind to rest. I was worried that I may have 
messed up my assembly, but it turns out that this thing is so sensitive that it 
can hear/interfere with itself!
Kind of like the ringing in my ears.

Do you by chance have ATTN on the KX3 engaged? If so, turn it off, and turn on

Re: [Elecraft] New PX3 - question on a signal that doesn't move

[Thorpe, Jeffrey]

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.

[Elecraft] New PX3 - question on a signal that doesn't move

[Thorpe, Jeffrey]

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)?

You can also use a short section of 2" PVC with a couple end-caps that have

Re: [Elecraft] XG50 temp comp for KX3

[Thorpe, Jeffrey]

One other question: at the very end of the extended procedure, it says (in 
bold) to kake sure I do the refcal procedure at room temperature as it says in 
the manual.
Am I supposed to do the refcal again? - after the extended procedure? Or is 
this just a note/reminder regarding the reference calibration that I do before 
the extended procedure?

[Elecraft] KX3 firmware request - separate internal/external power supply settings

[Thorpe, Jeffrey]

Right now there is just the "Bat Min" setting that gives an alarm if the 
present voltage drops to a set value in the configuration menu. (Automatic 
shutdown happens at 7.0V according to the manual.) I use an external LiFePO4, 
and internal NiMH. These have different specs. I would like to see more 
configuration options that allow me to "disconnect" the external LiFePO4 when 
it reaches a certain voltage (10V) and then switch to the internal NiMH which 
may be (and likely are, at least in short order) at a lower voltage than the 
external. I would also like to be able to have the ability to make the 
auto-shutdown happen at a higher voltage than 7.0V (8.0V in this case.)

Under the current setup, power is supplied by the higher voltage supply, which 
can result in a ruined external battery (if the internal protection circuitry 
of the battery should fail) as the power supply would flip-flop between the 
two. I would like to have a little bit more control. Maybe that's just a 
personality defect.

[Elecraft] KX3 Switch Tones

[Thorpe, Jeffrey]

I've noticed that with switch tones set on (SW TONE) that the KX3 will transmit 
the tone out the speaker port when in data mode. Shouldn't this be disabled in 
data mode? It does it whether transmitting or receiving, and messes things up.

[Elecraft] KX3 filter "sweet spot"?

I'm going though the FLDigi manual and have come across (at the "Operating

'sweet spot' and setting parameters for it in the configuration screen. How do 
you find that? Is that just a 'given' at a particular frequency for the KX3

Not that the SL is complicated but looking for a smaller interface. I've

Re: [Elecraft] Is there a 1500w amp from Elecraft in our future??

[Thorpe, Jeffrey]

As far as I'm concerned, putting a KX2 or 3 (or any Elecraft transceiver for 
that matter) out on 1500W is insulting to Elecraft and the user. While I am 
typically a "brute-force" type of guy, it just seems like such a waste of such 
an elegant product. Now if I had to communicate with somebody on Pluto through 
crazy storms, then yeah. But here, even with these current band conditions? 
There are other ways to spend my money. Skills trump gear.

Re: [Elecraft] KX3 memory - odd behavior with RCL

[Thorpe, Jeffrey]

Good lesson: read Fred Cady's book carefully when puzzled. It was in there. I 
just needed to pay better attention.

Guess I misunderstood how channel hopping worked, not ever having tried to use

[Elecraft] KX3 memory - odd behavior with RCL

[Thorpe, Jeffrey]

Does anyone else notice this:

I hold RCL, dial VFO A to select the memory I want, then tap any key to exit.
Everything looks ok, until I try to tune VFO A, but instead of normal tuning, 
it rotates through the memory channels again, but only within the same band I 
started out in. (My memories are all in sequential order of frequency, so I 
don't know if it would 'hop' over any if they weren't sequential.)

VFO A won't go back to normal tuning until I've tapped Band+ or -.

Re: [Elecraft] KX3 / KXPD3 "hanging"?

Got a few responses. Turns out it was the grounding problem. Did the mod with

[Elecraft] KX3 / KXPD3 "hanging"?

[Thorpe, Jeffrey]

I've finally gotten back to working on my morse, practicing with my KX3 with 
the KXPD3 attached. At first I thought it was just me, as I am just relearning 
this after 30 years of non-use. (Straight-key back in high-school)

I have the KX3 set for text decode, and speed set to 15wpm. Quite often, it 
seems to "hang" for a fraction of a second (variable time, but at times up to 
almost a full second). Usually it is with the right paddle (the dah). I can 
have the paddle pressed, but I don't get the dah right away - sometimes. Quite 
aggravating.  I tried bumping the speed up as a test, with the same problem 
still occurring.

I figure this could be a contact problem, but thought I'd ask first before 
doing any kind of disassembly, to see if there was some other known issue 
(maybe with firmware) first. I have the latest firmware installed. The KXPD3 is 
about one year old, and I have just now started using it.

[Elecraft] KX3 Auto Power Off suggestion

[Thorpe, Jeffrey]

Just a suggestion for an upcoming firmware update:

How about allowing an auto power off more selectable than 20 minutes or less 
(plus infinite)?

Sometimes I need to leave, and while I am recording to my tablet, I'll be gone 
for a few hours, coming back to everything dead (batteries in both).

Being able to select up to, say, an hour, would be good (for me at least).

[Elecraft] KX3: ALC on digital issue

[Thorpe, Jeffrey]

I've followed the directions in Fred Cady's book and the steps in the fldigi 
manual for setting receive and transmit levels. (Use the 'tune' button in 
fldigi, adjust computer output to 4 bars on ALC  meter, keep mic setting where 
I use for voice - 5) and all seems ok to this point. When I go to transmit 
however, all bars on the ALC meter come on.
The only thing different is when using 'tune' I have output set to 0 watts. 
When transmitting it's set to 10 watts. Any ideas?

Actually you can. The camera kit includes stereo speaker and microphone

[Elecraft] KX3 IQ output question

[Thorpe, Jeffrey]

I was under the assumption (yeah - I know...) that the IQ output was 
"unmodified" by your settings on the radio. However, when I run the IQ out to 
my panadapter (I use iSDR on my iPad Air through a stereo USB soundcard) I 
pretty much have to turn the PreAmp off. With it on I get a full screen of 
"green" on the waterfall. With it off the green is just where there is activity.

So, do I have some setting that needs adjusting (aside from turning off the 
PreAmp)?

Re: [Elecraft] OT: Contesting / DXing practices

[Thorpe, Jeffrey]

Thank-you Jim, you are correct.
Wes, no I am not talking about you.

As I wrote off-list earlier to another person:

My complaint, specifically stated earlier, was about the the operators who are 
all within 200 miles of each other (and me and those I am talking to). 
Actually, we're nearly all within 100 miles. I have no problem with people 
"blasting" to make a DX, or get through in a contest - that's the nature of the 
beast. I'm just talking about basic politeness for a casual ragchew. If people 
did that, there'd be leas bandwidth crowding, and a smaller possibility of 
encroaching government regulations on us in the future. I certainly don't want 
to be forced to go 'narrow-band' like happened to commercial.

Re: [Elecraft] OT: Left-handed paddles

[Thorpe, Jeffrey]

This discussion has brought to mind a question - maybe two. I'm relearning CW, 
and have the iambic made for the KX3. (When I first learned CW for my Novice 30 
years ago, it was with a straight key. I ended up not touching Ham when I went 
into the Navy, and just recently got back into it.)
So, as a rightie, should I start off sending with my left? If I do, should I 
reverse it? Would that make it easier to swap to my right? Or, just start 
sending with my right? (Well, four questions.)
For copying, I do it the old-fashioned way - pen and paper, and shorthand 
scribble-characters. I don't want to be tied to having to use a keyboard or 
other device. Yeah it's slower, so what.

Re: [Elecraft] OT: Contesting / DXing practices

[Thorpe, Jeffrey]

The band plans work better when operators actually abide by "using only the 
power required to make contact." In fact, the band plans might much less 
important if operators would bother to follow the "power rule."
Friends and I, who do happen to live fairly close, can (and do) actually talk 
using .1-.2W (yes, those are decimal points) on 40m, NVIS. It is really 
irritating to get stomped on by some jerk(s) running several hundred watts to 
talk when they're less than 200 miles away, as happens here in southern AZ.

[Elecraft] KX3 Utility on Mac - Sound Card for DATA A - no output

[Thorpe, Jeffrey]

I tried following the directions in KE7X’s book (7.5.2) to try and get a handle 
on how all this works, but ran into an odd problem - the KX3 utility program 
doesn’t seem to put out any sound. I unplugged the cable from the 
headphone/line out jack on my Macbook Pro and it was completely silent. Didn’t 
matter if it was CW, RTTY or PSK31. I then tried it on Fldigi and that program 
would output sound just fine. If I disconnect the USB/RS232 cable, then the 
Utility program does nothing.

So, is there a known problem with the Utility on Mac, or am I likely doing 
something wrong?

(on another note, how do you search these archives without manually crawling

Yes - in fact it works quite well at only the 5w limit using the internal 
batteries. You will need external power to get 10w output.

40m during the day, 80m at night.

There are better - and cheaper - ways to go for NVIS. Go to DX Engineering's 
webpage and look for their "paper" on an NVIS antenna to build. A quick 
websearch will also turn up similar plans. These are all based on the US 
military's NVIS antenna system. You do not need the "special" parts DX offers, 
although I did get wire from them.

The antenna system is a crossed inverted V with the apex being 15ft high, the 
wires and rope (I used 550 paracord) are the guy-lines. Instead of a long coax 
for the feedline I used 300ohm ladder, but that can be a pain as you need to 
keep it off the ground. It does keep the weight down when packing though. For 
at home, I will be switching to coax. I also use an Elecraft BL2 balun (set to 
1:1) at the KX3 before the feedline. (After the switch to coax, I will be using 
the balun set to 4:1 at the feedpoint.) From what I've read, a balun isn't 
required, just recommended.

I also have the internal tuner option - very important. I have used the above 
antenna on 20m also, and have made contact with Denver (I'm in southern AZ), a 
distance of about 650miles on 10w.

73,

Re: [Elecraft] New KX3 Owner: Power Supply Question

[Thorpe, Jeffrey]

I guess my big question is why doesn't the KX3 show the voltage come back up to 
15V until after some period of time? My multimeter shows the panel is putting 
it out, and I'm also not transmitting. As far as I can tell, it's not doing 
anything different than when I've just turned the radio on. I'm just wondering 
if this is 'normal' or if the radio has a problem.
I certainly don't expect to get more than the 5W, let alone 10-12, with the 
panel. The panel is for backpacking, and is considerably smaller and lighter 
than a battery.

[Elecraft] New KX3 Owner: Power Supply Question

[Thorpe, Jeffrey]

I’m a new KX3 owner - in fact, I’m pretty new to Ham and this is my first radio 
apart from an HT.

What I’ve done is hooked-up a solar panel to it with a shunt regulator. The 
panel is rated for 18V and 18W, and my shunt regulator limits the output to 
15V. (I have the battery charger/real-time clock option installed also, and the 
solar panel will charge the internal batteries.) With the KX3 on, it shows the 
internal batteries at 9.9V, and the PS at 15V. While I can set the transmit 
power up to 12W, it does drop to 5W when I try to transmit. This doesn’t really 
surprise me, as I expect the KX3 requires more current than the solar panel 
will deliver. The power supply voltage reading on the KX3 drops to 10.1V (while 
it shows the internal batteries still at 9.9V.) Oddly, even when I stop trying 
to transmit though, the power supply voltage stays at 10.1V. Unplugging the 
solar panel and replugging it does not change the reading back to 15V, it just 
goes to 10.1V when coming back off the internal batteries. When unplugging the 
solar panel, I take a reading with my multimeter and it reads 15V at the output 
of the shunt regulator, but when attached to the KX3, the KX3 still says 10.1V. 
I have a12V A/C adapter (only rated for 1A though) and if I plug it into the 
KX3 it reads 11.8V. (just to see if it might be a problem with the shunt 
regulator, I used it with the A/C adapter, and it did not appear to be a 
problem.)I then plug the solar panel back in and it says 10.1V again. So I 
leave the panel unplugged, monkey around with the KX3 and dig through Fred 
Cady’s manual for awhile, plug the solar panel back in, and I get 15V. Then the 
process starts all over.

Any ideas why the voltage from the solar panel/regulator doesn’t come back?
