Re: [Elecraft] 32 bit Elecraft Utility Apps

[David Fleming via Elecraft]

Yes.. No worries. All new releases of the Mac and Linux versions of the 
Elecraft Utilities will be 64-bit. As a result, OS X 10.6 (Snow Leopard) will 
no longer be supported and users of 32-bit Linux will need to upgrade to a 
64-bit distro. This will be a gradual process as new revisions of the Utilities 
are released.

Out of curiosity, is anyone still using OS X 10.6?

Re: [Elecraft] KX2 and SCS Pactor Modem Setup

[Erlend Grimseid]

Finally something i can help with. :)

I have used an scs DR 7400 modem with my KX3 for some time,  with great
success.

The first thing you would need to do is to make an cable to connect the tnc
to the radio. I made an custom plugg of two stereo male plugs and one
female. From the head phones connector i connected one side to the cable
going to the tnc, and one side to the female connector for monitoring.
Remember to hook up the ptt line as pactor is really sensitive to ptt
timing. All molded in polymorph plastic.

If anyone is interested i could make a quick write up on my blog.

Then for settings. I suspect that the kx2 would be similar to my kx3.

And credit where credit is due. I got this from Greg VA7BC.

On radio (KX3):
-MODE: USB or USB Digital
-COMPression: OFF
-Turn MIC gain off then gradually increase during PACTOR transmission so
that 4 ALC bars are lit
and the 5th bar may flash occasional. For me, MIC=3 does this
-AF gain = 2

Also remember to turn off vox, and sett mic button to ptt BEFORE entering
Digital mode on the kx3. I dont know with the KX2, but with the KX3 I could
not change this after switching to data mode. This might have changed with
software updates. I have't checked.


In RMS-express select radio K3 as the dont support KX3. I dont know if this
will work with the KX2.

Give me a line if you have any questions or if anyone is interested in a
blog post on this subject.

Re: [Elecraft] 32 bit Elecraft Utility Apps

[Dave Sublette]

Good morning David,

A curious bit of circumstance forced me to use an earlier version of the
Apple O/S recently.  My old Mac Mini died when its UPS went hysterical and
cycled the power violently several times.  I bought a new one, complete
with 16GB RAM and the 1TB Fusion Drive (and a new power backup system).

My old Mini setup ran Parallels and Win7/64 so I could run several amateur
radio programs on it.  When I tried partitioning the new drive for 250GB
for Boot camp. It wouldn't do it.  There is a BUG in High Sierra that
causes this and I have informed Apple of it.  They have had others report
the same.  They had  o way to fix it at the time I was having the problem
in late March.

My solution was to wipe the new drive and install an earlier version  -- in
this case 10.6 -- temporarily.  The older disk utility will partition the
new drive the way I needed it.  After installing Win7/64, I reinstalled
High Sierra and all was well.

This is an example of how I had to drop back to an older O/S, if only
temporarily.

73,

Dave, K4TO

[Elecraft] K3s and KX3 driving KPA500

[Michael Blake]

Prior to acquiring an ACC cable to interconnect my KPA500 to the K3s I used an 
RCA WYE cable to allow me to parallel the KEY signal from both the K3s and the 
KX3 to the KPA500.  This has worked well allowing me to get about 350 watts out 
of the KPA500 when driven with the KX3.

After reviewing the KPA500 schematics it appears that pin 10 in the ACC cable 
is diode ORED with the KEY In jack so connecting the K3s via the ACC connector 
and the KX3 via the KEY IN RCA jack should work as before.

Is this correct?

[Elecraft] Subject: Astron VS-35M Powwer Supply V-

[William Levy]

I agree with Joe. I do not like the connections with modern radios
concerning power and also microphone. I loved the old Cinch Jones on Drakes
and Swans or 9 Pin Collins Power Connections. This power pole stuff is
really rotten weak and cheap and the same goes for the Mike connections.
Concerning how spectacularly the Elecraft radios work on RX and also TX and
how delighted we are I sincerely hope that the K4 will have inputs we are
happy with. Why are the CW and Earphone jacks traditional when everything
else is cheap and junky?

Always use DATA A mode for data. That is a USB mode that automatically turns

On the other hand, the K3 Utility has to my knowledge never been available for 
ARM, 32-bit or otherwise.
32-bit Linux is pretty dead as OS on desktops/laptops. Sure, many embedded 
systems still are 32-bit, but the K3 Utility is a desktop application.

Re: [Elecraft] Elecraft Digest, Vol 168, Issue 13

[Bob McGraw K4TAX]

With #10 AWG wire for the DC power cable, set the supply no load voltage 
to 14.0.  This is well within the safe operating range of the radio per 
Elecraft specifications.     [Minimum 11.0 volts, Maximum 15.0 volts]


In transmit 100 watts, you should see 13.5 volts or more at the radio.   
You can easily and accurately monitor the voltage at the radio, no load 
and load, by setting the DISP to read voltage.  If you have more than a 
0.5 volt drop between receive and transmit in CW mode, 100 watts, key 
down, either there is a power supply regulation issue, or the IR drop in 
the power cables and connections are  excessive.


Also, the radio should be connected direct to the power supply terminals 
and not through some other power distribution means. { I don't care what 
the advertisers say.} IR drop is IR drop and every conductor and 
every connector is a contributor to IR drop.

My 70amp Astron has 1/4" lugs and they seem to make a secure connection.
Do to my longer lead length (power supply on floor) I used 8ga wire. This
was difficult to stuff into the K3S sized PowerPole. Even with the shorter
leads that I use on contest expeditions along with a switching power
supply I found that I need 10ga wire to keep the voltage above 13.5 on TX.
I think that larger PowerPoles or studs would have been nicer for those
interested in keeping the K3S voltage in the desirable range. Double as
Joe suggested would also work if you wanted to run two sets of wires.

Re: [Elecraft] Astron VS-35M Powwer Supply V-

[James Wilson]

Buck,

Running a heavy power supply line with a lighter gauge wire at
the radio end OR a lighter wire at the power supply end, the
overall net supply resistance (and voltage drop) will be the same.
For example, 100 Ohms in series with 1 Ohm equals 101 Ohms net total
resistance.

Likewise 1 Ohm in series with 100 Ohms is still 101 Ohms.

It doesn't matter if you take the voltage drop at the input or
at the output end of the power run if the total load is at the
end of the run.

I checked with Dr. Ohm to verify this.  :-)

Re: [Elecraft] KX2 and SCS Pactor Modem Setup

[Don Wilhelm]

All,

While those connections and settings may work, I see 2 things that can 
be considered improvements.


First is to use DATA A - its default sideband is USB and it turns off 
compression and EQ leaving your normal SSB EQ and Compression settings 
as you choose.


Secondly, using DATA A turns the MIC input into a LINE Input which will 
make the MIC Gain settings more mid-range.  A low setting of 3 does not 
have very fine granularity which may give trouble setting the KX2 ALC to 
4 bars with the 5th bar flashing.


Also in may be better to lower the audio levels elsewhere in the system. 
 This is basically a soundcard audio application, so the information on 
my website www.w3fpr.com may be helpful - on my site, scroll down the 
left column to the last entry and click to open that link.  It has 
information on setting the various audio controls that may be available 
(set them to mid-range to start).

Finally something i can help with. :)

I have used an scs DR 7400 modem with my KX3 for some time,  with great
success.

The first thing you would need to do is to make an cable to connect the tnc
to the radio. I made an custom plugg of two stereo male plugs and one
female. From the head phones connector i connected one side to the cable
going to the tnc, and one side to the female connector for monitoring.
Remember to hook up the ptt line as pactor is really sensitive to ptt
timing. All molded in polymorph plastic.

If anyone is interested i could make a quick write up on my blog.

Then for settings. I suspect that the kx2 would be similar to my kx3.

And credit where credit is due. I got this from Greg VA7BC.

On radio (KX3):
-MODE: USB or USB Digital
-COMPression: OFF
-Turn MIC gain off then gradually increase during PACTOR transmission so
that 4 ALC bars are lit
and the 5th bar may flash occasional. For me, MIC=3 does this
-AF gain = 2

Also remember to turn off vox, and sett mic button to ptt BEFORE entering
Digital mode on the kx3. I dont know with the KX2, but with the KX3 I could
not change this after switching to data mode. This might have changed with
software updates. I have't checked.


In RMS-express select radio K3 as the dont support KX3. I dont know if this
will work with the KX2.

Give me a line if you have any questions or if anyone is interested in a
blog post on this subject.

Re: [Elecraft] K2 - Revival of a resting one...

[Don Wilhelm]

Jon,

I don't think the serial number information for older K2s is still 
available from Elecraft.


As for the upgrades, I suggest you download the instructions for the K2 
A to B upgrade.  That is only the basic upgrade.  The 1st page of the 
instructions lists several other upgrade kits.  Download the 
instructions for each of them to determine which (if any) have been 
installed on your K2.  Installing all of them will give you a K2 that is 
almost equal to a new K2.


In addition, changing the IF crystals to the current crystals will 
improve the filters on your K2.  If you have the KSB2 board, change 
those crystals as well - Elecraft sells a set of 14 matched crystals for 
the K2 and KSB2 as well as a set of 7 for the base K2 only.
While you have the crystals off the KSB2 board, it is easy to change the 
filter capacitors to extend the filter bandpass from the original 2.1kHs 
to the new 2.4kHz - the capacitor kit is SSBCAPKT.


As far as firmware, upgrade the MCU and KIO ICs to the new version.  The 
only other firmware upgrade that is needed may be the KSB2 which should 
be upgraded if you ever add the KPA100.


The KAT2 wiring change was only valid for a short run of boards when the 
vendor printed the boards upside-down.


Download the KSB2 PSK mod instructions to see if you have the updated 
resistor and capacitor changes - if not, change them.


If all that is done, your K2 will perform like a new one.

73,
Don W3FPR

Been looking over the various places of K2 lore, for updates and so 
forth,  Sverre's site, Don's, and of course the Elecraft site.


First order of business ,  is it possible to have my S/N looked up? 
Found a database that I don't seem to be in,  found that the Elecraft 
list archives go back to 2001,  but I'm not finding a post of mine in 
there,  so hopefully the Elecraft Records Repository would still contain 
it somewhere. Then I can proudly post it on the bottom of my mails, like 
it was done back in the day.  ;-)


Next,  I have a range of boards for it, the NB, SSB, Antenna tuner, 160m 
antenna, and just built my long languishing KIO2 kit, to bring this 
K2-10 into the 21 (20th?) century.   I have started to go thru them and 
see if I have all the mods and etc that should be done on them,  have 
done many already,  but back about '03-04.  Guess this is just a matter 
of looking things up,  though I have a few questions there and probably 
will have more.


Another next,  I've been having difficulty checking to see which 
versions of firmware are the latest,  and what the various versions 
add.  Is there a version change log or something like that?


Here's what I have so far,  looks like the two main ones are down a 
bit,  but I don't know what I'm missing,  or if I really need the updates.


MCU    2.01f
RF        1.02
KSB2    1.04
ATU 1.03 f

Here's the PCB versions marked on the boards:

Main rev A
Control rev A
ATU     rev C (note, the board does NOT match the picture of the recent 
note stating some cut and jumper rework should be done on a rev C)

NB and 160m  rev D
SSB    don't have,  will have to yank it to read

So, the beginning of a journey.   Will greatly appreciate whatever tips

Sure there are 32-bit desktops out there, therefor I wrote pretty dead, not 
completely dead ;-)
Two years ago, Ubuntu did a poll and 92% answered they used the 64-bit 
version. Now that is hardly representative for all distributions, but on the 
other hand it was two years ago...
Maintaining a 32-bit desktop is getting harder and harder. Bugs that only 
affect i386 is getting more common as hardly anyone testing new versions run 
i386. And the 3GB memory per process limit is starting to be a real issue.
The larger distributions will probably drop i386 support in a year or two.

Let's not get into a technical Linux discussion here. We hams probably keep 
old computers around way longer than the average user. The (sad) truth is that 
most people today see their laptops and phones etc as consumables that you 
through away after a couple of years.

I agree that providing both a 32-bit and a 64-bit version would be nice. But 
if Elecraft need to chose between either 32-bit or 64-bit (and two versions 
obviously cost more than one to maintain), then 64-bit is the obvious choice 
today.

[Elecraft] K1 BUILD ISSUES

[KENT TRIMBLE]

The following two issues arose during a K1 build that, while obvious to 
some, weren't to me, and probably wouldn't be to many . . .


(1)  Even though the Errata sheet says trimmer caps C13 and C20 "may 
look different from what is shown", the trimmer caps shipped with recent 
K1 kits not only look different, they are structurally different in that 
they have no "flattened" side which is the indicator for how they are to 
be mounted.  However, continuity testing between the tuning slot (the 
metallic tab that the screw driver turns) and each contact leg will 
reveal that the leg with the continuity is the same as the "flattened" 
end.  I would have guessed it was the leg with the dab of red paint but 
I would have been wrong.


(2)  At first I thought I was missing eight 0.1mf capacitors said to be 
labeled "104."  A strip of eight, blue, square components with no "104" 
was remaining in the RF board bag, and I eventually surmised they 
constituted the missing capacitors, although they looked different from 
any capacitor I had ever seen in my 58 years in the hobby.


My thanks to Don Wilhelm for saving me a lot of extra work.

Suspecting the K1 and K2 kits are probably not long for this Earth, I 
bought both last Fall with the intent of building the K1 this Spring and 
the K2 this summer.  A close friend talked me out of my KX1 a while back 
which, for some reason, resurrected an urge to build again.  I've built 
all the mini-modules and the big rigs, but screw-driver assembly isn't 
nearly as satisfying as solder-assembly.

Kent Trimble, K9ZTV

Use *realistic* resistance values.  For example, a 10 foot piece of
of #8 wire (0.63 milli-Ohms per foot) with a six inch "pigtail" of
#12 wire (1.5 milli-Ohms per foot) is equivalent to 11' 3" of #8
wire or less than one foot of #12 wire.

The *contact resistance* in a 15A Power Pole (0.88 milli-Ohms) is,
*by itself,* is equivalent to more than six inches of #12 wire.

Ohm's Law is *exactly* why we would all be better off if the power
jack on the K3/K3S was doubled up and the power cable replaced with
#6 or #8 wire even if it were necessary to splice in some 4" pieces
of #10 or #12 wire to mate with the 15A Power Pole connectors.

#10 or 1/4" bolts for the power terminal with #8 wire and ring
terminals on both ends would reduce the voltage drop in the power
cable by 75%, if the bolted connections were torqued properly,
compared to #12 wire and 15A Power Pole connectors.

For example, 100 Ohms in series with 1 Ohm equals 101 Ohms net total
resistance.

Likewise 1 Ohm in series with 100 Ohms is still 101 Ohms.

It doesn't matter if you take the voltage drop at the input or
at the output end of the power run if the total load is at the
end of the run.

I checked with Dr. Ohm to verify this.  :-)

[Elecraft] [KX3] New Product: SPX3 External Speaker

[Robert J. Morris]

I've built a prototype powered external speaker for the KX3, and would
like some feedback on what folks would desire in terms of features, and
whether folks would want to own one. 

The speaker currently is designed to match the overall look of the KX3
and PX3, and accept similar third-party panels and covers as for the KX
line. Presently, it uses the same legs and feet as the KX3 and PX3, and
is the same height and depth as those. There is one USB port for
charging the internal lithium battery, and input and output stereo
jacks. The speaker is mono. The output jack redirects the right channel
from the stereo input for a second speaker, just like with the Elecraft
SP3 and other similar external speakers. The speaker is amplified. 

The SPX3 puts out a maximum of 3W, and is about as loud as any external
radio speaker gets. Volume is adjusted by the KX3. It plugs into the KX3
PHONES jack. There is a built-in low pass filter to reduce noise and
improve the listening experience. 

The prototype, as you'll see in pictures in the links below, is slightly
narrower than the expected finished product. The speaker driver and
on/off switch are both waterproof, but - just like the KX3 and PX3 - the
case isn't. So, don't drop it in a lake. It will handle all conditions
appropriate for the KX3, and is meant for indoor and outdoor use. Having
matched the case design so closely to the KX3, it isn't as airtight as
I'd like it, so the next prototype will have the case halves join in a
more customary way, but remain the same dimensions and overall look.
This will also improve ingress protection. 

You'll see the speaker is not a polished finished product yet, as it's a
rough first prototype made by hand. Your feedback will assure the final
product is what you want gracing your portable shack. 

Please note, the KX3 in the photo is only to demonstrate the speaker. 

All feedback is welcome. Please let me know which reasonable
enhancements or simplifications you'd like to see.
Examples:
* Would you want an output USB port to use the speaker to charge your
phone?
* Would you want to dispense with the built-in battery, and run it
entirely from external power?
* Would you want a second passive speaker driven by the first to save on
weight and cost? That is, a SPX3A (active, with battery, charger, and
amp) and SPX3P (passive, with only speaker driver)
* If you're a KX2 user, would you like me to produce the SPX2 (also in
development)?

Cat 5 cable has a different twist on each set of pairs. Those range from 52 to 
72 turns per meter or 1.94 to 1.38 cm per turn. That works out to 15 to 22 
turns per foot.

Re: [Elecraft] K1 BUILD ISSUES

[Don Wilhelm]

Kent and all,

The K1 needed to be discontinued because the enclosure metalwork was no 
longer available, and the cost for a new vendor to tool up was prohibitive.


OTOH, the K2 is around and selling for just as long as possible. 
Procurement of thru-hole components becomes more difficult as 
manufacturers are switching to all SMD components.  So far Elecraft has 
been able to provide suitable substitutes such as the SA612 IC mounted 
on a carrier board so it can be used in a thru-hole board.  Other such 
substitutions will be coming in the future, but Elecraft is dedicated to 
keeping the K2 kit alive for as long as possible.

Suspecting the K1 and K2 kits are probably not long for this Earth, I

which, for some reason, resurrected an urge to build again.  I've built 
all the mini-modules and the big rigs, but screw-driver assembly isn't 
nearly as satisfying as solder-assembly.

Re: [Elecraft] K3S birdies?

[Fred Jensen]

We had a sudden case of "birdies" in a K3 on 160 at W7RN.  Strangely, 
they began abruptly as you tuned up the band [around 1838 IIRC], and 
extended for *exactly* 15 KHz where they then disappeared.  Problem 
turned out to be a shield dislodged from the syn.

Make sure the internal cables with the little TNC connectors are all seated

Hi All.

I've been monitoring this list for a while, and have gained some
useful insights from the posts. And now I have a question...

I built my K3S #11310 last July, and I added the 100 watt amp and
sub-receiver last December.

A few weeks ago, I started hearing some unusual tones around 14380 KHz
and 7259 KHz. The tones are much louder on 14380 than on 7259. At
14380, I hear a lower-pitched tone on 14279.80, and a higher pitched
tone 14279.85. I hear both of these with no antenna connected. On 40m,
the tone is quiet enough that the background noise overcomes the tone.
But on 20m, the tones are quite loud. I also hear the tones on the
sub-receiver.

Prior to a few weeks ago, I'm certain these tones were not present. I
saw the thread from 2012 about moving cables around in a K3, but if
there was a build problem, wouldn't these sounds have appeared
immediately? My routers are far away from my shack, and there is no
new equipment in the shack.

Any thoughts?

Thanks.

[Elecraft] Astron VS-35M Powwer Supply V-

[j...@kk9a.com]

That is some lossy wire in your example:)  The reason for the lighter
gauge splice suggestion was to provide a way to connect heavy wire to the
Elecraft K3 and K3S. I can directly connect 1 awg wire to my Astron power
supply but technically only 10 awg to the small PowerPole connector on the
transceiver.

Yes. This is done to minimize inductively coupled crosstalk between 
pairs, which is critical to Ethernet transmission. A pair from CAT5/6 
cable used to carry audio or RF provides very good rejection of 
differential mode coupling to/from the cable. It's a great choice for 
telephone wiring if RFI to the phone line (including DSL) is a problem. 
A CAT5/6 pair is also a great choice for adding a ferrite common mode 
choke to a low band receive antenna. I've completed a set of 
measurements on this and will publish an applications note in the near 
future.

Re: [Elecraft] Astron VS-35M Powwer Supply V-

[Edward R Cole]

I run all my 12v equipment (almost anyway) on a 50A Astron PS.  Since 
the PS is rack-mounted in a half-height cabinet the dc cable is about 
12-foot long, so I used #4 welding cable that terminates on a 30A 
Fuse holder.  That feeds two HD barrier strip terminal blocks (for 
pos and neg rails).  The terminals accommodate No. 10 awg cables to 
the heaviest current loads.  A secondary strip handles small stuff 
(under 5A total).


The PS runs 13.71v and drops to 13.5v at the fuse holder.  K3 sees 
about 13.35v (radio is 10w version).  I have only two PowerPole 
equipped pieces; the rest use terminals or other connectors like 
Molex, etc. (even one Cinch-Jones).  I count 14 loads connected to 
the 13v power distribution (not all are used simultaneously).


In the case of running to a regular-sized PP connector I just add a 
few inches of no.14 awg (splice is two wires soldered and covered 
with heat shrink)

Re: [Elecraft] K2 - Revival of a resting one...

[Jon]

Hi Don...

Well,  so far I'm pretty certain I did the A > B changes,  and I did do 
the IF and the SSB crystal and cap filter mods.  I'll be reading thru 
that again,  in my first look I got the impression there might have been 
a later, better, version of the Xtals? Wasn't sure.   PSK was just 
starting out, and I recall doing the IMD improvement change. (What ever 
happened to PSK-31 and keyboard ragchew contacts, anyway?  Ooops, don't 
want to start anything...)


Finally building and using the KIO2 is pretty slick,  have been running 
WSJT-X and monitoring some WSPR and FT8,  kinda cool to have computer 
control of the rig, watch it do auto bandswitching while collecting WSPR 
spots.  I still have to find the spare mic connectors I used to have 
handy and build the TX half of the cabling.  Don't worry K9YC,  there 
will be #31 ferrite involved...   And, I'm pretty sure I did the Pin 1 
issue mods, grounding the mic shell and headphone jack solidly...


OK, the AT issue sounds like it happened after my board.  And, someday I 
might get the KPA100 and do the two box setup, so the KSB2 FW update is 
something to remember.


I know I used to have my S/N in posts here... kinda surprised I haven't 
been able to find a single post of mine,  going back thru the reflector 
site archives. I had the kit around 2000,  would think I was chatting 
away into 2001 or longer,  where the archive ends.  I dont see any 
easier search method than opening a month at a time though,  might be 
missing them.  Anyone know if there's a more comprehensive search 
method?  My S/N was in the 1500's,  if I remember right...


Definitely need to go thru my filters,  had been tweaking them a bit,  
not in the way you're supposed to,  and I know they're not right now.  
Have a few audio spectrum programs that we wish we had back then,  so

As for the upgrades, I suggest you download the instructions for the 
K2 A to B upgrade.  That is only the basic upgrade.  The 1st page of 
the instructions lists several other upgrade kits. Download the 
instructions for each of them to determine which (if any) have been 
installed on your K2.  Installing all of them will give you a K2 that 
is almost equal to a new K2.


In addition, changing the IF crystals to the current crystals will 
improve the filters on your K2.  If you have the KSB2 board, change 
those crystals as well - Elecraft sells a set of 14 matched crystals 
for the K2 and KSB2 as well as a set of 7 for the base K2 only.
While you have the crystals off the KSB2 board, it is easy to change 
the filter capacitors to extend the filter bandpass from the original 
2.1kHs to the new 2.4kHz - the capacitor kit is SSBCAPKT.


As far as firmware, upgrade the MCU and KIO ICs to the new version.  
The only other firmware upgrade that is needed may be the KSB2 which 
should be upgraded if you ever add the KPA100.


The KAT2 wiring change was only valid for a short run of boards when 
the vendor printed the boards upside-down.


Download the KSB2 PSK mod instructions to see if you have the updated 
resistor and capacitor changes - if not, change them.


If all that is done, your K2 will perform like a new one.

Jon,

If you want to confirm that you have the latest crystals, look at the 
label - it it says 4913-S, they are the latest.


If you add the KPA100, you should have the K2 Keying Waveshape Mod.  The 
keyclicks were not apparent with the K2/10, but with the added KPA100, 
they became obvious.  A kit is not currently available from Elecraft, 
but I can tell you which parts to order and email the instructions.
Check your Control Board.  If you have an electrolytic capacitor behind 
U4, then that mod is installed.


Did you record the K2 serial number on or in the manual when you built 
it?  Worth a look-see.

Running a heavy power supply line with a lighter gauge wire at the radio end

For example, 100 Ohms in series with 1 Ohm equals 101 Ohms net total

Likewise 1 Ohm in series with 100 Ohms is still 101 Ohms.

It doesn't matter if you take the voltage drop at the input or at the output
end of the power run if the total load is at the end of the run.

I checked with Dr. Ohm to verify this.  :-)

Re: [Elecraft] KX2 "HI CUR" Warning

[Chris]

Thanks to everyone for your assistance. After exhausting the ideas
suggested in this thread, I did have to send my KX2 to Elecraft for
service. They determined the issue was "U20, U22 drivers for PA at fault."

Looking at the schematic, these two components appear to drive the final
FETs.

Does anyone have any ideas as to what may have caused this failure? It's
not clear to me whether a high SWR could have provoked this.

Note: U20 and U22 are located on schematic "Assembly E850729", Sheet 3
of 4. It has these as SGA7489, but this part may be discontinued.
Elecraft replaced both of these with part E600447/ GALI-84+.

73,
Chris (KD2FLH)

Speak for yourself Sir.

There are 100's of 1000's of us out here with older hardware, happily
running current 32 bit os's such as Mint 18.x 32 bit, and all works fine.

Why follow the MS/Apple flock of sheep, just because they are moving to
64 bit systems?

There is no advantage for 99.9% of users, to move to a 64 bit OS,
whatever the flavor.

The hardware wont support the oft quoted 10's of GB of RAM (even if the
CPU might.)   Plus, for the ram we've got, with the system maxed out (be
that 4, 8, 12 or more GB) any given app takes twice the space compared
to 32 bit code, same with the storage.

It's marketing BS foisted on us by the likes of MS and that Fruit company.

Plus you then have to load 32 bit compatibility tools in some OS's, to
carry on running the software you have!

So why bother...

As to the K3/KX3 utility, well, the transfer to the radio is over an 8
bit wide path.  Need I say more.

73.

Re: [Elecraft] Elecraft Digest, Vol 168, Issue 14

[BJ ROLLISON]

First, just to be transparent I worked as an software engineer at Microsoft for 
20 years.

I agree there is sometimes no need for some users to move from a 32-bit system, 
to a 64-bit system. For example, if you have a computer dedicated in your 
shack, and mostly run apps for amateur radio or the internet, do not do run 
multiple programs simultaneously and switch between them frequently or do a lot 
of code crunching or image processing than you may not need a 64-bit machine. 
Also, since it is very unlikely that most amateur radio apps will likely be 
ported to 64-bit anytime soon.

However, there is tremendous advantage of a 64-bit system over a 32-bit system 
for many users who use their computers for more complex operations besides 
running a few limited apps and browsing the web.

Simply put, a 64-bit system will process large amounts of data through RAM more 
efficiently compared to a 32-bit system. In layman's terms that means that 
searching a large database of QSO's will take less time; especially if you have 
other apps running in the background.

While a 64-bit system will use more memory space compared to a 32-bit system; 
it is false to say the space is 2x more.

The 64-bit system also allows users to exceed the 4Gb limit of 32-bit systems. 
And many modern apps are memory intensive. Also many users who multi-task apps 
on their computers, use memory intensive programs (photo processing, code 
crunching, etc.) or use browser apps that are constantly auto refreshing, will 
greatly benefit from a 64-bit system. Also, while a 64-bit system will use 4GB 
of RAM more effectively, I personally would not recommend anything less than 
8GB of RAM.

Re: [Elecraft] 32 bit Elecraft Utility Apps

[Bob Nielsen]

If you want to run 64 bit Linux on a Raspberry Pi 3, you will probably 
need to use a different distribution than Raspbian, which currently only 
exists in a 32 bit version.

On the other hand, the K3 Utility has to my knowledge never been available for

32-bit Linux is pretty dead as OS on desktops/laptops. Sure, many embedded

Unless you ran it under emulation (e.g. wine or something like that), I

Re: [Elecraft] 32 bit Elecraft Utility Apps

[Joseph Reed]

Actually there is a Linux version of the KX3 utility.  The error posted 
suggests it might have been the Windows X86 version, or needs to be compiled 
for the ARM processor instead of the Intel/AMD.  Regardless the source code is 
not available so move along folks, nothing to see here.  And since Raspbian is 
a Debian derivative you would kind of sort of think it would work. Debian, 
yuck, CentOS :)

All of my Pi 2B and Pi 3 units are deployed with application specific tasks.  
But I have a couple of Pi Zeros that aren’t earning their keep.  When I can 
find the time I’ll test it.

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.

Use *realistic* resistance values.  For example, a 10 foot piece of
of #8 wire (0.63 milli-Ohms per foot) with a six inch "pigtail" of
#12 wire (1.5 milli-Ohms per foot) is equivalent to 11' 3" of #8
wire or less than one foot of #12 wire.

Re: [Elecraft] 32 bit Elecraft Utility Apps

[tomb18]

So forgive me but is it the case that the 32 bit elecraft utilities will not 
run on 64 bit operating systems? If that's the case then elecraft will release 
a 64 bit version of the utilities. If the 32 bit utilities  do run on a 64 bit 
OS then what's the point? There is no point. A 32 bit version of their 
utilities will work just as well as just fast over a rs232 connection no matter 
if the OS is 64 bit 128 bit or 256 bit. So the question is will these utilities 
not run on a 64 bit OS? They are 32 bit and run just fine on 64 bit windows..

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] KXPA100 fan for dig modes

[Walter Underwood]

I see it is spec’ed for 12 V. Does it catch fire if you run it on 13.8 V, like 
most ham power supplies? Or 14.8 V, like my shack?

Re: [Elecraft] [KX3] New Product: SPX3 External Speaker

Hi Paul, 

Thanks for sharing your interest. I'm glad you don't want a USB output
port. Although it wouldn't be difficult, it's beyond the purpose of the
product.

Re: [Elecraft] 32 bit Elecraft Utility Apps

[Martin Sole]

This probably started with the Mac OS thing. My understanding is that 
post High Sierra it will be just 64 bit and they will start dropping 
support for 32 bit so very possible that on a Mac lots of (some?) 32 bit 
apps may not work.


When are we going to see 128 bit OS's :)

OS then what's the point? There is no point. A 32 bit version of their 
utilities will work just as well as just fast over a rs232 connection no matter 
if the OS is 64 bit 128 bit or 256 bit. So the question is will these utilities 
not run on a 64 bit OS? They are 32 bit and run just fine on 64 bit windows..

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.

Re: [Elecraft] [KX3] New Product: SPX3 External Speaker

[Joan]

What I would love [to buy] for the KX2: a pair of speakers, thus: an SPX2A 
speaker (with an inboard stereo amplifier) which can be used alone as a 
monaural speaker—but which is also configurable for stereo audio with the 
addition of the optional SPX2P

Darmok and Jalad at Tanagra, said Piglet.
