[Elecraft] KIO3B or KIO3 board sets wanted

[Jim Cary]

I’m looking for either of the above board sets to replace a KIO3B set in my K3S 
which was damaged by lightning.  Replacement KIO3B’s have been on order for 
over a year now… supply chain issues.

Reply directly to me.

Re: [Elecraft] KIO3B Board

[w1rm]

The board is definitely not happy.  I plugged the aux cable into my KPA500
and as I cycle through the bands I keep getting invalid on the KPA500 screen
when it comes to band.  I have a call into Elecraft support.

Pete,

You might try one of these:

sr_1_3?dchild=1=serial+port+tester=1626916237=8-3

It will tell you if the serial output of the KIO3B is working.

Re: [Elecraft] KIO3B upgrade

[Joseph M. Durnal]

Hey Jim,

Replacing my external box (US Interface Navigator) with the KIO3B was
a change I was glad to make to my K3.  Audio levels are controlled two
ways, 1, in the K3 menus and 2, in the computer operating system sound
settings.  The application may also have adjustments for the audio
levels.  At first, losing my knobs made it a little more difficult to
set levels for different modes and applications, but once I got it set
just right, I found that saving the configurations made the
adjustments much more precise from and repeatable from mode to mode,
etc.  I really like the single USB cable between the PC & K3.

Re: [Elecraft] KIO3B upgrade

[Charles Hardt]

I have the upgrade on my K3.  Single USB cable that creates two virtual ports.  
One for rig control and the other K3 sound card.  I am talking about a Windows 
10 installation and operation.  I have done it in Linux on Raspberry Pi, but 
had to watch a lot of YouTube videos to adjust audio via a Pi Terminal screen.  
I find windows a lot easier.  In Windows you need to go in and find your serial 
port for both audio and rig control, just like you did with your Signal Link 
for rig control (I use a Signal Link with my KX3 and earlier with my K3 before 
upgrade).  Then to adjust audio go into Windows "Setup", "Audio Devices" and 
adjust your audio output (Typically speaker audio level) from your computer to 
K3.  Setup K3 to adjust your modulation level just like you did with the Signal 
Link.  Typically levels are lower than the radio's microphone.  Then adjust the 
audio in Windows, "Setup", "Audio Devices" as you did on the Signal Link.  For 
audio from the K3 to the computer just incr
 ease audio (typically computer microphone audio level) until your computer 
program begins to react to the sound.   Not sure what computer program you are 
using, but make sure you have selected the K3 USD sound card, typically called 
"USB audio codec" in your computer program.  Otherwise the computer program may 
default to your computer sound card (Not Good!).  I find windows adjustments 
very easy and can do it on the fly.  I work NBEMS HF & VHF and that requires 
audio readjust going from HF to VHF and back.  Getting rid of the required rats 
nest of wires with the Signal Link was worth it.  I was banking on your 
experience with the Signal link, so did not go into a lot of intimate details.  
So if more details are needed don't hesitate to get back to me. I really like 
the USB K3 interface with Windows and I am sure a lot on this list will 
disagree with me.  I have no experience in the Apple/Mac.

Good Luck,
73,
Charlie, N2PKW

Re: [Elecraft] KIO3B upgrade

[Wes]

You no longer have knobs, but the computer sound card controls and the digital 
app of your choice give you control of levels.  Use VOX in the radio and you 
won't know the difference, except for having a better sound card.

[Elecraft] KIO3B board ?

[Dana]

I got hit by lightning last summer and lost my KIO3 Rev B  - burnt inductors 
and 
Other damage.

One of the guys kindly sent me an Rev A version board, which I sort of got 
working, but
Its not quite 100% .
I had queried about surplus Rev B version boards, but lost the replies here, 
when I rebuilt my
Also damaged PC.

Does anyone have a Rev B version board set that they are not using, if you had 
upgraded to the 
USB sound card board KIO3B,  that they would be willing to part with? 

I want to see if I have further damage or not  or if its just Rev A vs Rev B 
related. 

Please let me know, as I try to diagnose the other “intermittent" issues…

Thanks 73
Dana VE3DS

Re: [Elecraft] KIO3B Main Board Repair

[Edward R Cole]

Received e-mail from Elecraft that my KIO3 board is being 
shipped.  Cost of new digital board $187.50 + $17.50 shipping.


So my K3 will be restored for operating JT65 on eme end of the 
month.  Only my 2m-eme array and tower crashed two days ago in high winds.

http://www.kl7uw.com/2m-eme_down_1.jpg

BTW I got my KX3 running on digital modes by use of a Rigblaster 
NOMIC.  I'll have a webpage up in a couple days with a description.

Anyone want to borrow Murphy for a few months!

Re: [Elecraft] KIO3B Main Board Repair

[Edward R Cole]

In my case the RS232 I/F in my K3 (SN-4340) quit communicating with 
WSJT-X.  Tested with K3 Utility with same result.  Tried a different 
USB/RS232 cable, still not communicating.  Troubleshot 9-pin 
receptacle and discovered the ground pin was not grounded.  Pulled 
out the KIO3A and found the chip inductor on the ground line had 
blown up open ckt.  Removed it and substituted a wire jumper (still 
not working).


At that point I was going to have to rig up a test cable to be able 
to troubleshoot the module unplugged from the K3.  Instead I sent it 
to Elecraft Repair.  They had it for 28-days and then replied that a 
new digital board was needed as the existing board was not 
reparable.  They are on order.


I did have the option to buy a KIO3B but that was over $400 before 
shipping (and also not in stock)  I don't need or use the USB port.


I worked 1966-2009: ten years as an RF engineer, and the rest as 
technician doing SM level troubleshooting/repairs.  After retiring I 
had a small business building transverters and amplifiers from kits 
(all SM).  I have a pretty decent workbench and test equipment to 
26-GHz.  II could have spent the effort in building a test jig and 
trying to troubleshoot on my own.  I figured it easier to let the 
experienced staff at Elecraft do it.


Hoping to get my KIO3A repaired when board order arrives.  I've 
decided to set up my KX3 for computer modes using a Rig Runner NOMIC 
I/F.  I'll post the project on my website when done.  The KX3 will 
use WSJT-X for running JT65B on 2m-eme by driving a 2m transverter. 
on 28-MHz with 3w.

You can view the Schematic diagrams (6 pages) for the Elecraft KIO3B module.
https://ftp.elecraft.com/K3S/Manuals%20Downloads/E740323%20K3s%20Schematic%20Files.pdf
The KIO3B is a multi-function module, that includes these functions:
1. RF Board interface
2. Digital I/O interface
3. Audio I/O interface
4. USB, Codec, RS232
FTDI FT232R (USB), TI PCM2901 (CODEC), TUSB2036 (2/3 port USB hub)
5. Digital I/O
6. Audio I/O
==
It is NOT impossible to repair or troubleshoot (component-level),
BUT it can be time consuming for the novice or weekend technician.
This is why Elecraft stated ?economical? (their bench time is NOT Free).
?
Sage advice from my high school electronics instructor, WB9FUR (sk, 
2016) has served me well : External event (ESD, Over-voltage, Op 
error) and I/O ports are major causes of module or circuit 
failures.  Electronic devices rarely ?die? for no reason (assumes QA 
production of part).

?
?What functionality? has failed will narrow the circuit areas and 
components to examine.  IF you can ?think thru? those observed 
symptoms, many failures can be pinpointed with a DVM to a few key components.

SMT repair experience and tools reduces repair time

This summer, I repaired an ESE ES-188 Master Clock ... that the reseller 
suspected was not working properly.  Visual and operations inspection:
* Not damage to tinned copper foil traces on PC board.
* Bulging 25V electrolytic caps (85° import brand) on DC filtering - replaced 
(105°)
* Multi-serial TTL level ports from microprocessor were inconsistent 
- replaced MAX233 (resolved one port)
- replaced 74LS04 and 74LS08 (resolved other ports)

I did not even pull out my DVM ... the secondary DC ripple was eliminated, and 
an external event (ESD?) likely entered thru serial port ... damaged the 3 ICs 
replaced.
Those 3 parts were closest to DC power bus and serial port entrance to PC board.

It’s been running on the bench, driving NTP and IRIG-B remote clock for past 3 
months ... no issues.  IF I were to resell, I would check with DVM & possibly 
scope.

I have ended up with 2 bad KI03B boards E850645.
Both bad in the USB circuit.
I did some basic checks resistance wise they recommended, but found no problems.
Elecraft said chances of repair was slim and would not be economical to try.
I think all the other functions are okay (think they are still working okay if 
you come in via the serial port).
Seems a shame to toss them into the dumpster, but unless someone has had 
some experience of repairing them that may be the route.
Anyone ever attempted at repair of the USB circuit on these??

I receive audio via the USB just fine with a plug in the LINE IN jack

Re: [Elecraft] KIO3B waiting list

[Edward R Cole]

Thanks!

Links provided by John, KC7DRI provided enough info for me decide I 
did not need the enhancements.  I run two LP-Pan SDRs off the first 
IF's of my K3 main and sub-receivers in diversity mode to provide 
dual IQ streams to my computer so having an internal soundcard is no 
use.  The USB/RS232 conversion cable works FB for keying my radio.


Plus I have the PR6-10 which works well for 10m-6m and Digout-1 is 
handy function for connecting my remote 6m preamp for eme.


I would buy a K4D except my K3 is working fine for my application as 
IF radio on 50-MHz thru 10-GHz.  I promise my wife when I bought the 
K3 in 2010 it was the "last one".  Yeah, she didn't really believe me.


Getting to the age where investing in ham radio stuff is not really a 
good long-term investment.  Bought a new F250 diesel truck and 
30-foot 5th wheel trailer in 2016/2017 and made two trips with 
it.  Can't leave AK this year due to corona-virus so will be second 
summer it has been parked.  Beginning to doubt wisdom of that 
purchase. (roughly $70K).

My K3, SN4340 dates from 2010 so assume it has a KIO3 board (not

I did add EXREF, TCXO3, upgraded both Synth boards and Gen Coverage 
filter to cover 475-KHz (630m) band.  I have the subRx installed.

I'm not as constrained as they are with respect to buying parts (surplus

[Bill via Elecraft]

I was assured in an email back in June
that the  KIO3B kits will be available as soon as things return to “normal” and 
parts are available. Anyone interested should be asked to be placed o the 
waiting list.

[Elecraft] KIO3B - different audio levels?

[Udo Langenohl - DK5YA]

I've upgraded both of my K3 while ago with all parts available to make 
them K3S (more or less).


My main K3 shows some weird behavior with the audio level comparing left 
and right stereo channel (KIO3B). I'm feeding this K3 mainly with 144 
transverter signals from XPol yagis (moonbounce system) with the Hpol 
signals on the main RX and Vpol signals at the second RX (AUX). Main RX 
is left channel on the USB soundcard while SUB RX is the right channel 
(Windows 10, MIC input).


Even when on both RX (main and sub) the HF signal level is exactly the 
same (i.e. -120dBm from a HP8664A signal generator, split by 3-dB for 
main and sub) the left audio channel (main RX) shows exactly 6dB less 
compared to the right audio channel (sub RX) at USB audio out. On the 
IF-side (28 MHz) signal strength is exactly the same level, measured 
with my Siglent Spec Analyzer. Just .34dB difference main/sub.


This doesn't happen on my 2nd K3 which is almost exactly the same inside 
like #1 except it's a 10W version.


Any idea?

Udo, DK5YA

Re: [Elecraft] KIO3B usb com port not communicating

[Jack Brindle via Elecraft]

Do you have BOTH plugs connected to the P3? You need to use the cable that has 
not one, but two DE-9 connectors - this allows the data to flow from the USB 
interface through the P3 and then back to the K3S. Without it, I would expect 
exactly the behavior you describe. In fact, I experienced exactly the behavior, 
which is why I know.

Be sure to use the double DE9 cable, not the one with just a single DE9.

Re: [Elecraft] KIO3B usb com port not communicating

[RALPH TURK]

Raj

Re: [Elecraft] KIO3B usb com port not communicating

Raj,

Don't overlook the possibility that the RJ-45 jack could be damaged.
If you have ever accidently plugged the USB cable into that jack - it 
almost fits, but will damage the RJ-45 jack.

Re: [Elecraft] KIO3B usb com port not communicating

[Don Wilhelm]

Raj,

Try looking in Device Manager again.  Which COM port goes away when you 
unplug the USB cable from the computer?  COM1 is normally reserved for 
the motherboard serial port - which will be RS-232 and not USB.  It will 
be there whether it is connected to the back panel or not.


Then plug the USB cable back in - which COM port is assigned?  Put that 
COM port number into K3 Utility and try to connect.

Paul,

The usual cause of destructive failures like these from lightning is 
interconnection of equipment powered from AC outlets having different 
green wires, or whose green wires are not bonded together, or equipment 
whose chassis are not all bonded together. This situation is made worse 
the use of shunt-mode suppressors on AC branch circuits.


Many years ago, colleagues working in pro audio design experienced 
destructive failures of the ethernet circuitry of networked computers 
from lightning. No antennas involved -- these were engineering offices. 
The solution for these failures was (and is) the use of series-mode 
suppressors on the AC line branch circuits. Surge-X is the manufacturer 
of these products that has concentrated on the pro audio and video 
market. There are (were) two other mfrs I'm aware of -- Brick Wall I 
remember, but not the other.

This is not exactly what you are describing, but it fails open.
https://hifimediy.com/usb-isolator

I've used one at a digipeater site and it took a static hit think - nearby
strike - it protected the TNC and PC.  It was open on every line.

I have used them for ground loops with sound cards.  5000v isolation
(advertised), but it did fail open!

Subject: [Elecraft] KIO3B USB Surge Suppressor

Looking for input from anyone who has successfully installed a
surge-suppression device on a USB port.  I am in the process of repairing a
KIO3B board after a recent thunderstorm.  

The KIO3B uses an ST Microelectronics USBLC6-2 ESD protection device at the
front end of the K3's USB connector.  The protection device is a SOT chip
that contains five low-capacitance diodes to clamp voltage to acceptable
limits.  

In this case, the diodes have shorted, causing the USB connector to show a
dead short to the PC's USB port, which causes an overload to the PC's USB
power bus.  This has caused all USB ports to disappear in Windows Device
Manager.  The short goes on until I can get to the remote site, sometimes
days or even weeks later.

Ideally, I would like to find a USB protection device that is designed to
fail open - open as in an open circuit into the USB driver that follows.
That way, I can still find a problem if Windows Device Manager doesn't show
a USB connection while not risking the destruction of the PC's USB power
bus.

Re: [Elecraft] KIO3B USB Question

[Don Wilhelm]

Rich,

The RS-232 lines in the K3 are essentially the same as the lines to the 
internal USB adapter.

That means that they are NOT two separate ports.

Yes, using the serial dongle that comes with the K3S or the KIO3B 
upgrade for the K3 does allow you to use an RS-232 port or USB adapter 
to connect to the K3, but you must move the switch on the back of the 
KIO3B in order to do that.


You would have to link the two com ports using a computer application, 
and I don't know of one that will do that.
i.e. take the COM port data from the K3 USB 'COM' port and feed it to 
the port that connects to the SDR.
As I recall, LP-bridge may have that capability, but it rather complex 
and I have not studied it.

You can connect a simple RD-232 Y cable to the PC port on the P3 with

Your SDR receiver must turn its driver off - it can listen to the

Re: [Elecraft] KIO3B Upgrade for K3 question

No more than a half hour, probably less.  I've
swapped KIO3 board stacks several times.

soundcard and only requiring a USB cable

None.  The conversion from DB9 to RJ45 jacks
for RS-232 (and P3 connection) is a pain if
one uses a real RS-232 connection and/or P3.

Re: [Elecraft] KIO3B Upgrade for K3 question

[Hisashi T Fujinaka]

Didn't take me that much time if I recall correctly. And not having an
external audio interface and easier RS-232 were exactly the reason I got
the update.

Re: [Elecraft] KIO3B Digital I/O assembly

[Jim Shepherd]

Having also hit the wrong hole while attaching cables from in front of the
radio, unless you have totally messed up the contacts, they can be teased
back into position with the careful use of a dental pick. BE SURE to
disconnect the power cable before attempting this repair...no telling what
damage could be caused by shorting a couple of the contacts together while
doing this repair... YMMV.

Subject: [Elecraft] KIO3B Digital I/O assembly
I am not sure how many of you have noticed the warnings in the K3s and P3
manual to NOT plug a USB B connector into the 8P8C modular jack lableled
“RS232/P3” on the rear of the K3s.  This is a VERY important warning but
only if you read it prior to inserting the USB cable (twice) into the
RS232/P3 jack on the KIO3B.

It was the very first plug I inserted after completing my kit while looking
over the radio from the front.  I did it twice because it did not seem to
fit correctly:). I did not realize that I had “squished” it for a couple of
weeks as I had not tried to use the jack.

Since this little bugger (KIO3B Digital I/O Assy E850646) costs $98,
believe it or not, I want to repair my existing board after the replacement
arrives tomorrow.  If I did it once I will probably do it again.

My problem is that there are dozens of similar jacks and I need to find the
correct manufacturer, part number and source for this particular 8P8C
circuit board mounted modular jack. I have the tools and the skills but I
lack the correct part.

If anyone from Elecraft could provide me with the proper replacement jack
information I would be very grateful.

Re: [Elecraft] KIO3B Digital I/O assembly

[Michael Blake]

I received this response today.  Thanks Keith!

Hi Mike;
We should have these sockets;
Elecraft part # E620328  CONN, JACK, RJ-45, SHIELDED

Feel free to post this, I get the Digest mode and it is awkward to reply to a 
single post.

PS, It is a common mistake, I have a stack of boards here that I repaired once 
we got the part in.
If the radio is on, sometimes it blows the KIO3B main board, an expensive 
mistake!
One can look into the socket, all the pins should be all the way down and all 
should be even.

Re: [Elecraft] Elecraft KIO3B and WSJT-X

[Raymond Sills]

HI Josh:


Another possible source of 12 VDC powered monitors is the Recreational Vehicle 
industry.  Many RVs have appliances (including TVs) that are powered from the 
"house battery", which is almost always a 12 VDC system.  And, many TVs have a 
VGA port on them... plus video, and HDMI, as well as an antenna port.

It's a good idea, but too severely limiting since almost all monitors

KPA500 on several bands with no issues. Final test will be pointing the

It is usually the POWER SUPPLY that causes RFI,  NOT the monitor. To

The mystery is why don't I have the same problem with WSJT 10?

Re: [Elecraft] Elecraft KIO3B and WSJT-X

[Josh]

So, you're saying everything is fine with 10 running, and as soon as you open X 
the S-meter goes up? If you close X with 10 still running does the S-meter go 
back down?

When you disabled CAT control in X, did you close the program and get back to 
the low noise level, then launch it again seeing the S-meter go back up? If so, 
with X running did you check in the settings to make sure CAT was still off?

When the noise is showing on the S-meter, does unplugging the USB cable make it 
go away?

Re: [Elecraft] Elecraft KIO3B and WSJT-X

[Josh]

That's really odd! It's quiet until the program starts?

What happens if you run 10 and X concurrently? Start up 10 first, it's quiet, 
then start X?

Audio config on X is identical to 10?

HA!! Try turning off CAT control in WSJT-X. I bet the program is changing 
something on the rig to make the noise come up.

Re: [Elecraft] KIO3B Audio I/O PCB Assembly

[Ted Edwards W3TB]

Interesting to read, Clay.
I just this month got the P3 Panadaptor and had problems at their
connections to the KIO3B.
I thought it was fixed when they sent me a new cable for the P3, but now it
is back on an intermittant basis and my connection to the computer USB has
gone, too.  I really do think it is within the daughter-board, but there is
nothing I can see there -- even looked for a cold solder joint through a
jeweler's loop.  Now I am really stuck...

Anyone have a slick way of securing the KIO3B Audio I/O PCB

Drives me nuts and can't be good for longevity on the multi-pin connector.

Re: [Elecraft] KIO3B Installation Problem

[Jim Sr Sturges]

Windows after 7 has a “feature” that hides com ports in the device
manager.  In the device manager, go to View on the menu bar and then
un-hide the hidden ports by clicking on Show Hidden Devices.

Re: [Elecraft] KIO3B Installation Problem

[Don Wilhelm]

Buddy,

Load new drivers in the computer.  The computer not indicating the COM 
port assigned is a computer failure.
After loading the correct drivers, go into Device Manager and open the 
ports section - unplug the USB cable and observe what goes away.
Then plug the USB cable in again and see what is added.  If it does not 
show the assigned COM port, the computer has a problem.

[Elecraft] KIO3B Installation Problem

[louis a. ives]

I read the post that Rick N6XI wrote about the problem getting the KI03B to 
sync. With ports.  I have the exact same problem with my K3 after I replaced a 
defective KI03B main board.  During the time that it took for my replacement 
board to arrive, my computer in the shack failed.  I purchased a new desk top 
computer and after installing the new board in my K3 I found that it would not 
sync.  I checked the devise manager for the port list and found no list.  I 
have tried everything to get them to show up in the list with no luck.  I have 
tried everything listed in all the posts and still no luck.   The K3 utility 
shows a blank port list and the KPA500 show a blank port list, but does have a 
refresh port button but no com ports listed. I have two of the same computers 
and both show no com port list in the Devise Manager.  Both of the computers 
have Windows 10 Home and will not work on the K3.  The old computer that was in 
the shack was a old Asus laptop with windows 8 but had 
 been updated to Windows 10 and worked great.  I suspect that it may be a 
problem with Windows 10 Home,  that something is missing.  The computer works 
fine.  If anyone has any suggestions I would appreciate the help.

Thanks, 73

Then the system has no serial ports defined.


The K3 shows up in Device Manager under Win 7 (IBM laptop) as a sound
device, a USB hub, and a xx232... other device 


Where does the "other device" appear - what section of the Device 
Manager "Devices by type"?


You should see the USB Hum and a "USB Serial Converter" in the
"Universal Serial Bus controllers" section and "USB Audio CODEC"
in the "Sound, video and game controllers" section.

Select the "USB Serial Converter", click the Advanced tab and
confirm that "Load VCP" is checked.

Make sure your computer is producing enough output drive. On my 
Mac I need to go to System Preferences -> Sound and raise the 
output volume all the way.


Make sure your application is addressing the correct USB device. 
(Don't ask how I know.)


Input from the radio should work but might be low in volume. 
Some of us set Config: LIN OUT to about 40.

Re: [Elecraft] KIO3B RTTY AFSK problem with Transmit

[Don Wilhelm]

Dan,

It sounds like you are doing things right.
What is the Speaker slider on the computer set to?  Open the playback 
controls - normally set it to about 75%.  The "meter" in the computer 
soundcard display will not tell you the whole story.  Go to the Playback 
Controls to see the slider (Windows - Mac or Linux may be different).


Make sure there is nothing plugged into LINE IN (it overrides the Codec 
line in).  You may want to insert a plug into the LINE IN jack and 
quickly remove it just to make certain the contacts in the jack close 
properly.


You must set the MIC menu entry to LINE.

Set the audio level correctly (you can do that in TX TEST or connected 
to a dummy load so you do not transmit RF).  Tell your software 
application to "transmit", then adjust the "MIC" gain (actually LINE if 
you have set the menu correctly) until you have 4 bars solid with the 
5th bar flashing.


If you cannot achieve that audio level by manipulating to Speaker slider 
on the computer and the MIC Gain on the K3S, something is awry - contact 
K3support for additional assistance.

[Elecraft] KIO3B: Another great Elecraft upgrade

[Bruce Nourish]

Hi folks,

Last night I performed the KIO3B upgrade on my new (old) K3. As with all
Elecraft projects I've done, documentation was great, and things work as
expected. A few minor things needed some thinking:

* I forgot to upgrade the firmware before installing it, but I was able to
get the right firmware version loaded over USB by toggling the KIO3B into
RS232/legacy mode.

* A hidden end of one of the TMP cables got loose while I was putting
everything back together, which caused an easily-fixed ERR PL1.

* The lack of sound scared me for a minute, but then I found the very last
instruction, to toggle the KIO3B speaker -/+ setting, and that fixed the
sound.

This is the neatest digital-capable ham shack I've ever had, and I'm
already happy I installed it. Thanks, Elecraft folks.

Bruce

[Elecraft] KIO3B

[Mike Harris]

G'day all,

Time to put this saga to bed.

Further investigation revealed that my Toshiba Netbook with a slightly 
earlier version of Logger32 (3.50.231) ran software CW (DTR keying) over 
the KIO3B USB port without issue. The main PC was running version 
5.50.252. I transplanted the Tosh version on the main PC and indeed that 
too ran perfectly OK. So what had changed between versions?


Eventually it was suggested that I should check in the CW machine config 
to see if "disable radio polling when keying" was checked. It wasn't so 
I did and that resolved the problem.


Curiously in the Tosh version 3.50.231 it wasn't checked but that ran OK 
on both the Tosh and the Dell so there is still something in play, 
however, the ripples in space time have been smoothed and I am back with 
a fully functional one cable solution for CAT/PTT/CW/Audio.


Many thanks to all who took an interest in this problem and all those 
who were fearful can rest easy. That is not to say your time won't come.


Regards,

Mike VP8NO

Re: [Elecraft] KIO3B

[Mike Harris]

Many thanks to all who have taken the time to respond to this thread. I 
will continue to try and resolve this issue and as a first step I 
plugged the K3 USB into my Toshiba NB510 Netbook, fired up L32 (slightly 
earlier version) and the CW machine and the software/DTR CW was fine.


The netbook has nowhere near the power of the Dell desktop so 
investigation is in order.


Regards,

Mike VP8NO

Re: [Elecraft] KIO3B

[Kevin Stover]

Sometimes there really is no good explanation because people don't use 
the same hardware, and thus have different drivers installed. They also 
have different software installed. The machine I'm typing this on is a 
quad core processor running at 4Ghz with 16 Gigabytes of ram and a pair 
of SSD's. This thing rips by anybody's standard. It won't run Adobe 
Flash worth a crap. All three browsers will lock up from time to time. 
Kill the Flash plugin and it works but there goes my "multimedia 
experience".


So, it could be hardware, it could be USB driver versions, it could be 
drivers for any of the hardware installed, it could be installed 
software. It could be Windows itself. Point is the Winkey bypasses all 
that stuff and is still "one wire compliant" in that it doesn't connect 
to the radio except the key jack which I assume may already have a 
paddle hooked up.

This is an approach that I'm working on since it can be sent from N1MM
function key strings (99% of CW contest sending) and can include rig
control commands and be blended with stuff that N1MM does well and doesn't
need change. Other folks are working on this and probably there will be a
collection of cute techniques that will emerge.

So far, so good.

Re: [Elecraft] KIO3B

One approach to reducing the cable mess might be to have the PC 
key the K(X)3(S) using KY programming command, making the 
radio's keyer send the CW. There are some existing programs 
which use this technique.


[My CW isn't good enough to know if it actually works well when 
operating north of 30 WPM.]

Re: [Elecraft] KIO3B

[Gary Smith]

Mike,

I am using a K3s but the KIO3B is the same for us and I believe the 
config settings are the same for a K3 with it. I have the USB from 
the KIO3B going to a powered USB hub with 5 devices total on it. I 
have the RS232 from the K3s going to a P3 with the CBLP3Y.

I was working the Stew Perry contest last night, using N1MM and using 

its macros to send CW. The only problem I had in sending is in 
remembering which function key to hit as using a keyboard to send CW 
is new to me (Well... I did have an Apple II+ back in 1981 that had a 

board in it for CW/RTTY but nothing keyboard to send CW since then)

Someone (here, I believe) kindly helped me with the settings to use 
with N1MM & the K3 and be sure if you use N1MM, to have in CONFIG, 
the PTT-KEY set to OFF - RTS. I don't know if any of this will help 
you but I can say that up to 30 WPM, there is no problem on this end 
whatsoever. Your solution will likely be easy to resolve once you pin 

it down.

73,

Gary

Re: [Elecraft] KIO3B

[lstavenhagen]

Goes back even further than that, all the way to the semi-automatic bug, in
my opinion. We used to put relay circuits on our keys to get reliable,
click/bounce free keying of our rigs, due to contact bounce and poor contact
in general in the bug's moving parts. I'm going to have to build one of
these for my two Vibroplex's in fact to properly key my elecrafts too,
because of the occasional 7 to 8ohms that appears when making the Dahs

For me, the only really working final solution to using a computer with my
rigs has been to unhook it from the rig completely. When I go operate, I
have the K2 or K3, a paddle or straight key and a pencil/notebook and that's
it. 

Yeah, I'll never win any contests, but at least I can key the rig. So at the
end of the day, I've found, computers and ham rigs ultimately don't mix.
Unless it's the elecraft panadapter...

Re: [Elecraft] KIO3B

[Guy Olinger K2AV]

This seems to be the same ole age old problem of relying on a PC keying CW
over a single lead on the RS232 connection or its stand-in (USB).

Over and over ad nauseum, literally thousands of times, this has been
discussed everywhere since before USB existed. Parallel port keying...if
you don't know what a parallel port is, don't feel bad, that's how old this
problem is...it first surfaced so long ago I can't remember how far back.
Parallel port keying seemed to be far less susceptible, with cleaner code
formation. But we all know what happened to parallel ports, if you even
know what one is.

I have not, in my entire life, heard a satisfying answer as to why the
difference.

The very large sample size conclusion: Some people can do that and sound
perfectly crisp, no matter what. Some will get infrequent odd scattered
distortions, that are not enough of a problem to worry about. Others are
driven to distraction with distortions sometimes bordering on hilarious.
Some computers have spells of it that come and go, seeming to correspond to
phases of the moon, alignment of planets, or giraffe mating season.

Some now have excellent results with straight, normal RS232, but USB routed
functions screw up. Others via USB lines do perfectly well. Others STILL
can't use the serial line approach AT ALL. Back in the day, slow CPU speed
and limited memory were often associated with the poor performance.

SOMETIMES, NOT ALWAYS, upgrades to the CPU and memory would fix it. Many
just gave up and went PERMANENTLY to WinKey (way, way cheaper than
motherboards and memory) based solutions, myself included.

The N1MM integration of WinKey devices is at this point flawless. And the
ability now to create tailored PTT, that changes with code speed from a
MicroHam box with embedded WinKey, is priceless.

There has NEVER, in all this decade of fighting this problem, been a silver
bullet solution that fixed the RS232 or USB key line problems. Over the
years I have literally seen hundreds of extended email threads about
dragged-on investigations by earnest and intelligent ham investigators who
never uncovered any solution except throwing bigger and better CPU's at the
problem, HOPING for better performance.

Some people having the problem, while others with similar or identical
equipment having none, simply means nothing. It has always been that way.
One swears that he did this or that and the problem went away, and it
really did go away when HE did that, he's not lying or deluded. But others
try the same solution and nothing changes.

Blaming key line over RS232 or USB problems on anything other than
poltergeist is just plain unfair. It just could be that one insulted Murphy
just one too many times.

I understand that people are trying to make cabling go away. Completely
understand. Been there, done that, failed. Back to WinKey, permanently. No
more wasting time, except my 432nd (or is it 610th, or 326th? I forget)
lifetime email on this frustrating problem.

I have other poltergeist to work on that have no convenient WinKey solution
standing by.

73, and I DO wish you good luck on this one, but don't count on it. PC's
and their constantly thrashing drivers and system program code just have
too many moving parts.

Same here too, well formed CW from both a K3 and a K3S using the KIO3B
board configured for USB. N1MM+ keys the virtual DTR line (no Winkey).

I have a Winkey. I use it.

I use Logger32 and prior to installing the KIO3B my 3GHz clock PC 
comfortably delivered software CW from within Logger over RS232 
without the need for a Winkey unit.
## How do you know that? It may work great at any specific time but 
sooner or later the CW will get messed up.
If you don't have a Winkey USB I'd get one, One USB cable to the PC and 
a key line to the rig. It's supported by all the contesting/general 
logging software. It's also a real good standalone keyer, better than 
the one in the K3(s).


I'd be using the RS-232 port on the K3s for rig control and the USB for 
audio in/out.

The one cable solution may not be.



Any thoughts.
