KIO3 Board

n3bud
 

I have been having troubles getting my K3 to send digital stuff since new.  Today I noticed the Line is loose on the board and the outer ring tab is no longer making connection.  Wondering if anyone in the group updated to the USB and has an old laying around they would like to get rid of.
Thanks,

Re: KAT500 AMP Key Interrupt Setting

Bob McGraw - K4TAX
 

The PTT command should go from the 7300 to the KAT500.  The KAT500 key line goes to the KPA500.  Thus anytime the KAT500 is tuning it breaks the  amp key line. 

It is all in the manual.

Tim,

In the N1MM+ Configurer, under the Mode Control tab, on the right-hand side where it says "Mode sent to radio", in the row labelled PSK, set the "Mode sent to radio" to PSK (this is an N1MM+ metonym for DATA A on the K3). Doing this should result in the radio switching to DATA A automatically when N1MM+ loads WSJT-X.

Not sure if this applies in your situation, but I'll toss it out there.  I just loaded WJST-X last week.  I immediately connected it to N1MM, so I can use it for FT8 general purpose logging or for contests.  I noticed that when N1MM loads WJST-X, it sets my K3 to USB mode.  WSJT decodes fine, but no job on transmit, until I switch the K3 to DATA mode.

Powerpole connectors are excellent if they are correctly assembled - but the instructions fail to warn that a "distinctive click" does *not* guarantee correct assembly.

Who can know what a "distinctive click" means until they are sure that they've heard the right one?

So here comes the first problem: when a Powerpole connector is assembled, there are often *two* clicks happening at different stages of assembly. The first click is a soft one, as the cable and connector blade slide into the plastic shell. If the cable and pin have not been accurately assembled, some force may be required, ending in a click.  An inexperienced person could easily imagine this is the "click" they were told to listen for - and it isn't.

Experienced people know that the *correct* "distinctive click" comes at the next stage, where more force is applied and the end of the connector blade hooks over the stainless steel leaf spring.

Another beginner's mistake can happen when assembling a two-pole connector. It is very easy to imagine that both blades have clicked into place together (because that's what is supposed to happen)... but maybe only one of them did? Everything feels OK, and the rig may even work for a while, but one blade lacks contact force and can even be pushed back, leading to intermittent contact. 

So don't rely on 'ears and feel' alone. The only way to make absolutely certain is to *look*. Check with a strong magnifier that *both* connector blades are correctly and completely hooked over the ends of their springs.

Re: Help with WJST-X, MicroKeyerII and K3

Joe Subich, W4TV
 

Have you followed the procedure in the "Setting Audio Levels" section
of the MK II Users Manual *EXACTLY AS WRITTEN* only advancing when you
obtain the result called for at each step?

The description of your problem sounds as if you have not set the
modulation level (MIC GAIN in DATA A - *AFTER* SETTING THE K3 TO
*LINE IN*) correctly.

In the case of the K3, the MIC GAIN encoder is overloaded - it only
adjusts LINE IN when in DATA A or AFSK A and MENU:MIC SEL=LINE IN.
Otherwise the LINE IN lave is zero and the MIC GAIN adjusts the mic
input (front or rear).

Mic SEL = Line In goes into transmit for a second or two, followed
by a beep and the WSJT-X error message "Error in Sound Input: An
error in opening the audio input device has occurred" The WSJT-X TUNE
button stays lit, but the radio is not in transmit and I hear RX
audio.
This is a WSJT-X error. You have configured the sound card selections
incorrectly within WSJT-X. Typically, that indicates selecting a
soundcard that is not present/not available in the operating system.

If you have a K3S, make sure the LINE IN and LINE OUT pigtails from
the microHAM cable are connected to the correct jacks *FULLY* seated
and that your digital software selects the correct sound devices -
LINE (microHAM CODEC) for receive, Headset earphone (microHAM CODEC)
for transmit.

Knowing nothing about the MicroKeyer II (I use the Navigator), I'll take a stab at it.

How is the interface hooked to the rig? Front mic connector, or rear panel mic connector?

If hooked to the rear mic input, did you select Data mode, and did you make sure you have Data A set?

Re: Problem - Solved

Alan Baker
 

Hi Bob.

I have already pm'd Bob (the other one <g>) regarding Anderson Power Poles.

When we were testing his K3 there were no issues moving it around or flexing my power cable, so I presume that there are no faults in the rig itself. The issue is most likely to be badly installed pins/shells on Bob's cable. To be clear - Bob did not make up that cable.

Most of the issues with Power Poles seem to be because installers use the incorrect crimp tool. It's imperative to use an 'official' crimp tool, otherwise the pins can get distorted and they don't fit the shell with the correct spring tension behind the pin, to ensure that it makes solid contact with its opposing receptacle pin.

I've always found slight difficulty in getting the pin to enter the shell correctly (I've sworn at them more than once <g>) but that's how it should be. When the pin is installed it needs reasonable force and there's a distinctive 'click' when it's correctly positioned. With the correct pressure from the backing spring, the pin should not move. If the pins get distorted, the previous conditions are often not met.

I suspect that if Bob re-makes the cable with new pins (using the correct crimp tool) all will be fully resolved.

Alan. G4GNX

Many have used these radios and their power connections successfully for
years. Many have used them under rugged conditions at DXpeditions
successfully. I have other brands of radios that use the exact
configuration of PowerPole mounting. There is not issue in my experience.

As to the power cable, mine that came with the radio purchased new from
Elecraft, is quite flexible and sized correct for the current
demands. I would then question if someone / previous owner has "made"
their own power cables. Would seem likely so.

As to a learning curve, reading the manual several times is an absolute
must. As to the noise made by the radio when moving it around, the
solution is to turn the radio off before moving it. Mine is in a
position which I have to pull the radio forward and turn it to reach the
back. Again, correct cables and type are the solution to correct
movement and does not cause issues.

Sounds as though your power pole connectors on the power cable are in poor condition.   I strongly suggest one crimp and solder the terminals on to the wire before they are inserted into the red and black sleeves.     A loose connection on the DC power source can reek havoc with the radio.

Re: Power output fluctuation

I think you have a newer radio, mine is #763 but has mostly been good to me.  Funny, there thousands of the K3 out there that you never hear about.  
I bought a KX3 at Visalia in April.  Not the same as a K3 by any means but it is a nice radio and will do what is designed for.  Have only done some receiving with it so far.  Just took it out of the box on Saturday! Still a lot to learn about how to work the controls, multi purpose buttons.

Re: Problem - Solved

Bob.

By 'touched the power connector' do you mean disturbed the power connector by moving it?

If that's the case, perhaps you need to check the power pole connectors on the end of your cable. I have spares if you need to re-make them.

I didn't notice anything untoward whilst we were moving the rig around whilst still connected, using my cable, so if there is anything loose it's not likely to be inside the rig.
There also wasn't any issue apparent when I did the equivalent of a drop test, so I presume that there's nothing loose within the rig.

Yes and by all means, always power the radio down / turn off by the POWER button before shutting the power supply down.

There is a circuit which saves the configuration when the radio is shut down by the POWER switch.
