Hi all,
I'm hoping someone has come across this problem and can help out.
I recently got an XG3, so thought I would run the Calibrate RF gain utility
in K3 Utility.
I'm running the latest K3 firmware and the most recent update of the K3
utility: 1.4.4.25
K3 and computer are communicating fine
Hello again,
Update to my last post: I turned everything off, went and had a cup of
coffee, came back and tried the RF gain calibration routine again with K3
Utility - worked just fine this time. So, not sure why those errors. I had
turned everything off and re-booted the K3, restarted the
John - I would say that if it is just flickering on and off that is
exactly right. It does at least show that the receiver is live and the
residual noise is registering on the S-meter. Perhaps if you shorted
ANT1 to ground the flickering might reduce.
Personally, if my S-meter did not
Just did the same procedure on my K3 (I have the sub-receiver installed in
mine) and everything in the RF Gain calibration routine went normally and
completed /wrote the value to eeprom for the main RX, but I got the No
response to DSP command error when the utility was going through the sub-RX

Dave,
Do a Google search for Coby CA-745, an FM wireless transmitter that plugs
into a cigarette lighter. You can find them at Amazon, Wal-Mart and Best Buy for
between $16 and $19. The input is via a stereo miniplug at the end of an
attached cable. The frequency can be changed and is displayed
Has anyone received a shipping confirmation yet? Maybe tomorrow is our

As a portable user of the K2 and Vertex 1210, I was thrilled to hear about
the new KX3.
After reading the preliminary specs however, I think I´ll stick to my
existing radios. Why?
- 10 W is insufficient power for portable SSB operation on the lower bands,
at least in Europe. 20-25 W as the 1210
Hello John!
In ABS mode this is normal. It is a consequence of offsets the DSP is
doing to account for the settings of ATT and PRE, along with the method
used to pass S Meter information to the MCU.

Hi Folks,
I've been trying out a couple external speaker ideas for some various
Elecraft products; both ideas save some desk space and so might be
considered where space is at a premium. One uses the Dell soundbar AX-510.
This unit mounts to the bottom of most recent Dell computer monitors;
I have been using WSPR, primarily on the 600m band (495.9 KHz), as
part of the ARRL 600m Experimental Group (WD2XSH).

The furthest my 4.15w ERP signal was detected was 2893 miles. I also
have tried it a little on 6m.
I have used its brother, JT-65, extensively on 144-eme.
Please excuse the triple post, it wasn't deliberate.
My internet connection has been up and down a lot due to local lighting storms.
Sorry..

Well, it's in the title really, but I was surprised to find that
turning the P3 off does not reduce the current reading on the K3
display (the P3 is powered by the 12v acc skt). That's a pity as it
would be useful to see the load on that socket without using an
external ammeter. Yes, I do have
Hi Stephen,
The aux 12 V output is not part of the current-monitored path. The
main reason for the current monitor is to keep track of the health of
the radio itself, so we take corrective or informative action in
either RX or TX mode.

Check the schematic. The aux 12V is really close to the 12V input,
being dropped by one diode and a FET junction. There's no shunt in
that leg. No way to measure I to the 12V output.

Hi Terje,
The KX3 is a completely different radio from the Vertex 1210. It is
much smaller, lighter, and has far less current drain. It can even be
used hand-held. There's simply no room for a 20-W PA and/or a large
battery.
The 1210 is a channelized man pack radio, which definitely has

I just (re)discovered that the Mic Gain (set with MIC SEL Tap [1]) is
the same for both front and rear mic selections. This is a bit
inconvenient when switching back and forth between very different mics.
Is this on the list? Or have I missed something?

Ok, you win, I´ll order a KX3 when it arrives!
I have quite a few 5-10w portable radios gathering dust unless I plan to
operate CW. My trusty K2 has the 100W PA, which I usually run at 25-50 watts
using a 14AH battery and an K1 tuner (which tackles 50W well in spite of being
rated lower). The

Note that the KX3 will have an effective SSB
clipper/compressor/processor to give an average of at least 6 dB of
talk power without significant impairment of the speech quality,
making 10W seem like 25 or more to the receiving station.

Hello
My factory built K3 is about six weeks old and today it started doing something
that I have never
had a rig do before in 40 years of hamming.
I was listening on 20 meters CW and the K3 suddenly started making a fast
ticking noise at various
speeds. The wind was blowing about 40 miles
Wayne,
Is the 150mA RX current of KX3 is with the LCD display on and some level
backlight active? What if there could be option to the display go to sleep
if no knobs are touched for some time? Kind of like screen saving mode.
Could that be considered? I bet the display takes considerable current
Knowing Elecraft design practices most likely the audio output is isolated,
so your concern is notwithstanding.

I use macros for PF1 PF2 to switch between the front rear microphones.
The macro can turn bias on/off , set gain and sensitivity (H/L). Some users
also use their macro to also set the frequency response diferently for the 2
microphones as well.

Hi Igor,
The 150 mA target is with the backlight off. It's a transflective
display, so it's highly visible even with no backlight, except at
night. But we'll have a low setting of the backlight that adds very
little current drain -- maybe 10 mA.
The LCD itself, and its controller, draw
All,
Has anyone seen any degradation or temporary non-operation in the QRP
versions of the K2 or K3 while operating in hot conditions? Symptoms
might include:
- gradual loss in output power
- gradual increase in output power
- controls stop working due to some processor lockup
- unexpected
Scott...
Lift the top panel and check the cables that run from the left side
across the fans in back near the finals. Betcha one is just nicking the
fan and making your ticking noise.

Hi Stan,
You can do it. I'm probably older than you (72) -- it just takes patience
and some fiddling.
The first thing to do is to plug in those patch cords. In fact, let's start
with just one. Plug it into the Lin Out on the back of the K3, and the Mic
jack on your computer.
Then bring up WSPR.
Hi John,
I have a 100W K3 here and my shack is an un air conditioned 20Ft container in
tropical north Queensland, Australia.
Needless to say, it does tend to get a trifle 'warm' in the wet (summer) season
here, with outside temps in the mid to high 30's (Celcius).

Somewhat less protuding knobs, as well as a thinner dial knob would be more
balanced with the rest of the unit, and would also be less vulnerable for
transportation.

You dont get confirmed contacts per say, but you can see your

It's even more amazing how far 0.5 watts can be heard and information
exchanged using human brains as the encoder/decoder software.
You can tell how far a few watts, even 100 mW (0.1 W) can be heard by simply
tuning in the NCDXF/IARU beacons on 20 through 10 meters - no computer, no
