Re: K3 KIO3B Line In problem - no audio into K3

Edward Seeliger KD5M
 

Good morning Joe.
Yes, there is a setting for the K3 to recognize the KIO3B in the menu and it is set to normal - KIO3B recognized.
Yes, if I plug the LINE IN plug from the microHam device into the LINE IN jack, the USB audio In is removed/disabled as it should be.
Thanks for your suggestions.
VE3KI also suggested that if the LINE IN gain is set too high, the K3 will not accept LINE IN - with the LINE IN gain (MIC control) set at 7-12, no ALC indication or RF out.

Still no LINE IN from the analog jack and no ALC indication or RF out from the K3.
Any other suggestions??

I have found that the ground sleeves of each plug MUST be actually common grounded. The socket sleeves of the Line In and Line Out are not common ground and have circuitry used, I guess, to minimize RF interference. Ensure that each line, In, Out, PTT has the coax sleeve connected.
That was my problem one time.

Edd,

I still think there is an incorrect configuration setting but thus
far have not found it.
Do you get audio from the K3's internal CODEC with a plug fully
inserted in the Line In jack?

Inserting a plug in the Line In jack should force U15 to switch
audio sources going from the KIO3B board set to the motherboard
and then to the front panel board. If you still have CODEC audio
with a plug connected at Line In, I would look at the choke in
the jack switch line (don't have the schematic in front of me
this morning) and/or other connections for the switch signal.

The other possibility - is there something in the KIO3 menu that
differentiates between the KIO3 and KIO3B that could be set to
KIO3? I never saw any reason to update either of my rigs to
the KIO3B (no different than adding a microHAM USB Interface III
with less capability) so can't check that one out.

73,

... Joe, W4TV

I had already noted that and assumed since I installed a new KIO3B board set that they should be okay.
But, to verify, I pulled the Audio Board and verified that L10 and L11 show continuity and also that I have continuity from the top of C7 through L11 to the top of C20 and from the top of C6 through L10 to the top of C19.
I also verified the same continuity on the old KIO3B Audio Board that I had removed.
The Analog LINE IN lines and the USB LINE IN lines converge at U15 on the KIO3B main board - since USB LINE IN works but Analog LINE IN does not there is not much circuitry that could be at fault.
I still think there is an incorrect configuration setting but thus far have not found it.
I am still looking for other suggestions to resolve this problem.

Thanks for the response.  This is what I have.  single wire 148 ft. I was considering bypassing  the KAT3 and going to an SEA1613 antenna tuner (used usually for shipboard 2 to 30 MHZ). Instead of using the external tuner can I go directly to the KAT3

Definitely! That's what the KAT3A was designed for. (All of our radios embody the Spirit of Field Day, going back to the K2. That means working with crazy, ad-hoc antennas.)

There are two ways to use a random wire with the K3:

1. QRP-only (10 W or lower):  Attach a wire directly to the antenna jack and throw it into a tree. Longer the better. Attach another wire to the ground lug, also longer the better. "Longer" is a general guideline. If you're only targeting a single band, you can optionally cut both wires to   L(ft.) = 234/F (MHz). This will avoid wires that, on your favorite band, end up close to a half-wave (very high-Z, with RFI more likely). For reduced RFI problems, use a balun right at the radio such as an Elecraft BL2.

2. QRP or QRO:  Create a random-length dipole, ideally off-center-fed (OCF), longer the better. Attach it to 30 to 50 feet of high-quality twin-lead or open-wire (ladder) line. Toss *both* ends into trees or use other supports. Use a balun (e.g. Elecraft BL2) at the radio to convert the balanced line to unbalanced and help shunt RFI away from the chassis of the radio.

The above will always work. You can finesse it from there with longer or more complex antennas and feedlines. See for example the ARRL Antenna Handbook. Or talk to K9YC :)

Given the number of requests we've received, we've decided to do another run of KAT3A modules for the K3/K3S. We have a small number in stock, ready to be shipped. Orders beyond that will be filled as soon as the next build is completed.

The highly reliable KAT3A covers 160-6 meters and includes a bypass relay. To paraphrase any number of customers over the years: "It'll match anything!" :) This is especially useful in a radio like the K3A, which is light enough and small enough for compact FD and DXpedition work.

Typically you can put up one or two antennas, then use them on many (if not all) bands -- thanks to the KAT3A.

Check L10, L11 on the audio jack PC board. If either of them
opens you will not get any audio from the "Line In" jack.

Re: K3 KIO3B Line In problem - no audio into K3

A couple of things to check:

In DATA A mode, MAIN:MIC SEL must be set to LINE IN. Once this has been done, the K3's MIC control controls the LINE IN level. It must be set to a vlaue other than 0 (LINE 0 will result in no audio).

If there is anything plugged into the Line In jack on the KIO3B, the USB audio codec in the KIO3B is disabled.

Good morning all.
I have a K3 upgraded with the KIO3B and other enhancements that I want to use with a microHam device for digital modes (WSJTX, JTDX, MMTTY).

I have spent the last week or more online with Elecraft Technical Support without resolution of the problem so perhaps someone here can point me to a solution.

The title is the short version.

I want to use the microHam device, not the built in USB KIO3B sound card for digital modes.
The K3 is in Data A mode and LINE IN / LINE OUT is selected as the input / output audio sources.
I have verified that with the K3 in USB mode, the K3 KIO3B USB sound card works for LINE IN and LINE OUT and the KIO3B digital part works for CAT and PTT.
With K3 set for RS232 (38400 baud) and connected to the microHam device via a microHam cable, CAT and PTT work and LINE OUT from the K3 to the microHam device works. I have verified that there is audio from the microHam device to the K3 (I swapped the microHam cable and also listened with headphones at the Line In plug on the microHam cable from the device). But there is no ALC indication and no RF from the K3 with K3 Line Level turned all the way up and output from the microHam device turned all the way up.
As a further test, I replaced the entire KIO3B board set with a new board set with no change in behavior - no ALC indication or RF out.

Does any one have any ideas how to resolve this?
Thanks for your time and any help.

My K3 is serial number 21 and is the first kitted K3.

During assembly, I was concerned about the tension of the pre-installed Anderson Power Pole attached to the rear panel.  It captured the mating connector but wasn't as snug as other APP connections I was used to.  Visually the internal metal tabs appeared to be properly locked.

A month later, NØSS (s.n. 8) and I were invited to display the only two K3s that had been shipped to Missouri at the 2007 ARRL Midwest Convention in Lebanon.  A multi-band dipole outside the arena allowed attendees to operate the radios on-the-air.  During set-up, I tripped over the coax and ripped out the power cable from my K3.  If the tension on that APP had not been as light as it was, the K3 would have ended up on the floor.

Tom's subsequent examination of both rigs revealed wires attached to the APPs on the inside were too short and thus displacing the metal tabs just enough to prevent solid hefty connections.

Bruce's serial number 158 experience, together with ours, probably result from factory growing pains at whatever facility was installing APP connectors in those early days.

The problem is that there is very little friction to hold the connectors reliably attached to the K3. They slip out far too easily.
