Jeff,
That is an entirely different jack used in the K3 (and KX3).
The retention on many 3.5mm jacks is not strong, and with only a slight
pull on the cable, the plug will become slightly unseated. I don't
think the ones used by Elecraft are any worse than the ones I have seen
on many
Richard,
I would suggest you re-check the soldering of the LCD pins. In fact, I
recommend that you solder them from both the top and bottom of the board.
Those pins do not protrude through the holes in the board. It is
possible to have solder covering the solder pads, but not in contact
I am building a K1. On page 37, Alignment and test, Part 1, when I turn
on power I do not get the e27 display. The LED test was correct. The
LCD only shows a few vertical bars on the top half of the display. If I
tap a switch, the display goes blank. All resistance and voltage checks
up
Count me as another fan of fixed mode. Now if my
PX3 can do it eventually, I'll be a happier camper
:-)

Was in the middle of the CQ 160 contest and the K3 shut down. There
is power to the radio but it is dead in the water.
The power supply is working fine, power getting to the rig, but
nothing. No fuse on the chassis, any suggestions? Lousy time to lose
the rig.

Yes I'd found that. What I was hoping for is a readout in watts, with a
bargraph,
like that provided with the W2 or the remote app for the KPA500.

I can’t imagine that paralleling four elements would make a big difference. It
would be more directional at higher frequencies. A 2x2 array would be about
20mm across, which is one wavelength at 17000Hz. That would start to be
directional, because angled waves would cancel out.

I did to see if there was voltage at the plug there is. I was in
the middle of transmitting and the radio went dead. No sign of life.
Power supply is working just fine.
Darn, I have put so much work into being ready for this contest.

Others have commented on the directivity problems with paralleling
microphone elements.
Regarding the gain that you mentioned, any electret element is going
to have a very high output. Much more than the K3 needs. The K3 can
effectively handle just about any microphone.

Hi Hank,
Just removed the K3 from its harness and tested the RCA jack to see
if it's shorted; Using the fluke it shows 500 ohms when the probes
are reversed, there's an infinite reading so I'm assuming the diode
is intact.
Guess that's not this issue. Thanks for the idea though.

Provides more gain and improves the SNR.

The OPERATE tab of the KAT500 Utility shows the VFWD and VRFL as well as
the VSWR. It also shows the Bypass VSWR. Perhaps that is what you are
looking for.

You are seriously misguided. Your combination of mics won't do that, and
they WILL make a mess of the sound they pick up.
The only thing to be gained by combining microphones is directivity,
doing that is VERY difficult, and microphones that provide directivity
are common and inexpensive.
Just a follow-up,
I found the problem and it is in the DC terminal strip that must have
a faulty component inside. It shows 13.8 V at the end of the wiring
harness but when I connected it to the K-3 it dropped down to .5 V. I
bypassed the terminal strip and connected to the power supply
I had the same problem with my 2008 sn 1502 K3. I tried cleaning the
contacts with no luck. Elecraft sent me the gold replacement contacts free
and after I installed them the problem has not returned. Not hard to do but
a bit tedious.

Be sure to keep your audio input (RX) as low as you can. Your pic could be a
result of high audio levels.
On my K3, I set LIN OUT at 1, then set the driver level just high enough to
allow decoding (3/100 in the Windows driver). Overdriving causes myriad
issues, mostly causing the decoding

I would submit that it is something internal -- but internal to the
wiring harness or the terminal strip that you are using.
The direct connection to the power source should indicate that this is
not a K3 problem.

A quick guess. The DSP bandwidth for Data A is separate than
from USB. Try adjusting the HI and LOW cut knobs on your radio.

bit of a learning curve with all these
Yep, there is always a first time for any mode. I remember when PSK31
was introduced and I tried it. Had a problem similar to yours, but on

I've used JT65 on my K3 many times, with DATA A as the mode. I can

Jean,
I am a little confused by your questions (it may be a language thing).
I assume that you have the K2 twins which have the KPA100 and KAT100
in the separate EC2 enclosure (I do not know what an ECS-box might be,
so I am making assumptions).
If you want computer control of the K2 Twins,
I tried JT65 for the first time today (there is a first for everything,
right?), and to my surprise, I discovered that for some reason, the DATA
mode is not usable on that program!
Not 100% sure the mailing-list allows images in emails, so I will try to
describe the issue as clearly as
Hi Elecraft members;
I already have build a K2/10.

Is there anyone who could give my some addresses and advise witch kind of
soundcard is usuable for
I have noticed that my LINE IN jack sometimes loses the input signal and I have
to apply a slight pressure to get it restored (gently push in on it). It's
fine after that unless I move the K3. Does this jack suffer the same issues as
the headphone jack too?

To remove the old headphone jack, you can de-solder it if you have good
de-soldering tools. If not, crush the body of the old jack (pliers will
work) sufficiently so you can remove the old pins one at a time. Do
whatever you need to do to preserve the thru-plated solder holes (do
