Re: [Elecraft] Nine month rested 2014 K3 now only shows a blank orange screen P3 will not activate.

[Ron D'Eau Claire]

One thing I'd do before the EEINT is to force a firmware load as described
in your owner's manual and see if that rescues it. Somehow data got
corrupted to prevent a boot up.

Start with the basics - disconnect everything other than the power and a
dummy load to the K3.
Then power it on.
If all is well in that basic configuration, then start adding the extra
things one at a time to find out what is creating the problem.
If the basic K3 still responds with a blank LCD screen, then try an EEINIT.
Hopefully you have saved a configuration file so you can restore the
configuration data after the EEINIT - if not follow the calibration steps in
the manual to get back to an operational state.

If that does not help, contact Elecraft support.

I would try pressing the buttons on the four encoder/switches 
(e.g. CMP/PWR) on the left side of the main VFO knob about 100 
times each, then try turning the radio on.


When these switches malfunction, all kinds of crazy things

Barry,

You said "Our Field Day operation uses all KX3s, 
QRP ... ".  Well that's a tad different than if 
you have some 500 W stations nearby operating near 
your frequency.  And that is more typical of the 
situation I described.  So rather than disagree 
you provided the exception that proves the rule :-)


And "the KX3 can handle any intelligently crowded

"intelligently crowded"!

There have been times when we found one of our

if the other radio is not in the same part of 
the band, you may not even know he is there.  
However, you know he's there.  If he is far 
enough away, you could work through him. There 
is one caveat. We do have our antennas really 
spread out. Our GOTA antenna(s) can be any where 
from 200'-400' away depending on which of our 
many antennas are being used at the time. And 
secondly, all of our radios are using the 8 KHz

I agree with all that Ron says -- and have the

Re "I am considering the KX3": The one caveat I

disagree with) this, is that if you operate in 
a dense ham environment like Field Day or with 
other nearby hams operating on the same bands 
the direct-conversion KX3 will not be as good 
as the two superhets because you may have more 
difficulty hearing weaker signals with those 
strong, nearby signals at adjacent frequencies.


In Auckland this may or may not be an issue for

the VHF range with a VHF "roofing filter" to 
set the initial selectivity.


The KX3 is quite different. It is a 
high-performance direct conversion
receiver using phasing to suppress the 
unwanted sideband followed by

filtering of the resulting audio.

I'm a casual, mostly QRP operator who avoids 
pile-ups (and so contests) and
enjoy all three. If I had to settle on one or 
the other I'd probably take
the KX3 as my first choice because of its 
small size, the "transparent"
sound of a direct conversion format and 
options such as the PX3 panadapter.
My second choice would be my trusty and ever

simply because I'm basically an "analog" sort 
of guy. But I have no
complaints about the K3/K3S. I'm sure others

of the K3/K3S.

Re: [Elecraft] Receivers?

[David Woolley]

I don't think these descriptions are accurate, particularly the K2 
versus K3 one.


The K2 is a fairly conventional, single conversion, analogue design.  As 
stated, it uses the crystal filter for primary selectivity.  It 
typically has up to two crystal filter options, one hard wired, and the 
other as an integral part of the SSB adapter.  The hard wired one is 
adjustable, and the SSB one is fixed.  The filters are constructed by 
the final assembler, from individual crystals.  Although there is a DSP 
option, it works purely on the audio.


The K3 and K3X are software defined radios (SDRs) of the non-direct 
sampling variety.  I use SDR in the technical sense, not in the amateur 
radio community sense; the latter requires the digital processing to be 
performed on a PC.  This means they have an analogue front end with at 
least one analogue mixer, but the final processing is done digitally.


The K3 has a double conversion superhet architecture, with an HF first 
IF and an extremely low second one.  There is a selectable crystal 
filter (using commercial sub-assemblies) in the first IF, which provides 
coarse selectivity.  The final IF processing is digital.  There is a 
quadrature path starting from the second mixer, analogue at that stage. 
 Combined with digital processing, this creates an analogue of a 
phasing design receiver to suppress the final IF image, rather than the 
audio image.  As the signal continues in quadrature, the digital 
processing may also act analogously to a phasing receiver to do the 
final conversion and audio image stripping, but it may be that the 
internal logic is more complex than that - the fine details are a trade 
secret, although they may or may not have release information about that 
part of it.


The K3 also does digital processing on the recovered audio, but this is 
done within the same digital processor as the final IF processing.


The K3X, for CW at least, implements a hybrid analogue/SDR direct 
conversion, phasing design.  For SSB it may do the same, but it is also 
possible that it actually implements a final passband centre at 0Hz, and 
then does a final frequency shift to move the centre of the passband to 
the correct audio frequency (i.e. they could have implemented it as a 
single conversion architecture).  Selectivity is provided entirely by 
digital processing.


For both the K2 and K3, first mixer image rejection is provided by a 
combination of band pass filters, optimised for each band, and a low 
pass filter, also optimised for the band.  For the KX3, the image is the 
one removed by the phasing, although there is also analogue band and low 
pass filtering - I'm not sure whether this is switched, or there is a 
single, compromise, filter.


Block diagrams for all three are fairly easy to find.  I have the K2, so 
did that from memory, but the K3 one is at 
 and the KX3 at 
. 
There are likely other places, including a better K3 image.

Re: [Elecraft] K3 sub RX off freq in SSB diversity mode

Dale & Milt,
That was fixed in firmware version MCR 5.33 DSP 2.86 in August of this year.
Some of us used a work around of averaging the filter offsets for both 
filters. In SSB it was ok not sure of CW.

Hello Milt,

I think this will occur with the original synthesizers, if you are using
dissimilar roofing filters while in diversity mode. For example, if you
have the 2.8 KHz filter installed in RX1, but the 2.7 KHz filter in RX2,
you will probably experience this (as I recall). If you can, try selecting
a bandwidth while in SSB mode where both receivers will be using the same
roofing filters (if they are installed), and see if the frequency shift
suddenly disappears.

I am not absolutely certain of the above, but I seem to remember that was
what I experienced before I upgraded to the the new synthesizers many
months ago.

There is a standard UHF - N  cap that is the same size and thread as the K3
mic connector.The number on it is "MX-913/U" and has part number"91836"
(Probably an Amphenol number.

I tried an all metal cap but did not like that much silver on the front of my K3
What I wound up with is the ring from a mic connector and a thin piece ofblack 
plastic so you basically see a black Center with a silver ring around it.

Re: [Elecraft] Getting Logger+ tx audio via K3s USB audio codec

[Barry N1EU]

I've gotten many good tips but my USB audio is still dead.  So I
simplified my attempt like this:

Mic+Lin off
Mic Sel Line In
Line Level 60 (max)
Nothing plugged into Line In

Set up Audacity loop playing audio file with Speaker output as USB Audio Codec
I see the Windows Sound Playback level jumping up and down as expected
- audio is going to the device

Push PTT on K3s and absolutely no tx audio

Is there anything I'm possibly missing?

situation that is worse than have a collection of radios operating in 
close proximity, to include their antennas.  QRP operation does offer 
the least challenges, but it still does have its problems. At the other 
end, the serious QRO stations like W3LPL all take special precautions in 
field layout and they use bandpass filters. However, I think you know 
all that.


We don't have Frank's acreage to operate. We have to live within 2 
acres for everything, but the KX3s do allow us to be less than 
absolutely rigorous in our operation. We chose what we do because it 
allows us to operate without the need to use bandpass filtering and the 
need to model our site so that everything will work. I suspect strongly 
we could operate at the 100 what level and still make no changes to our 
site or operation except that we would need to be careful to have only 
one transmitter on a band at a time, better band management.


One could argue the definition of the term intelligently crowed. 
However, I was thinking that for a co-site operation no two transmitters 
would be in the same portion of the same band. I may have a bit clumsy 
with the my definition on this one.


Bottom line: my original point is that the KX3 does survive quite 
nicely in what I would call an RF hostile environment. Will it wilt when 
things get really crazy? Yes, it will along with every other radio.

Barry,

You said "Our Field Day operation uses all KX3s, QRP ... ".  Well 
that's a tad different than if you have some 500 W stations nearby 
operating near your frequency.  And that is more typical of the 
situation I described.  So rather than disagree you provided the 
exception that proves the rule :-)


And "the KX3 can handle any intelligently crowded environment": Would 
that  all our bands were "intelligently crowded"!

I will take the given opportunity to disagree. Our Field Day

There have been times when we found one of our GOTA ops on the same 
band and in the same portion of the band. What we have found is that 
if the other radio is not in the same part of the band, you may not 
even know he is there.  However, you know he's there.  If he is far 
enough away, you could work through him. There is one caveat. We do 
have our antennas really spread out. Our GOTA antenna(s) can be any 
where from 200'-400' away depending on which of our many antennas are 
being used at the time. And secondly, all of our radios are using the 
8 KHz offset. I was amazed at the demonstration the first time it 
happened. I would say that the KX3 can handle any intelligently crowed 
environment.

Scott,

I agree with all that Ron says -- and have the K2, K3 and KX3 .. and 
like them all.


Re "I am considering the KX3": The one caveat I would add, and others 
can expand on (or disagree with) this, is that if you operate in a 
dense ham environment like Field Day or with other nearby hams 
operating on the same bands the direct-conversion KX3 will not be as 
good as the two superhets because you may have more difficulty 
hearing weaker signals with those strong, nearby signals at adjacent 
frequencies.


In Auckland this may or may not be an issue for you -- but as I 
recall 70% or so of New Zealand's population is in the Auckland area.

Re: [Elecraft] Receivers?

[Matt Maguire]

In the K3 schematic, I don’t see any quadrature path starting from the second 
mixer in the RX path — the two signals lines coming out of that 2nd RX mixer 
are a balanced (differential) output, not in-phase and quadrature signals. On 
the TX side, the DSP seems to produce I outputs, but it seems the I signal is 
not used for anything and only the Q signal is used as an input to the TX mixer.

This is in contrast to the KX3 where there are I signals used between true 
quadrature mixers and the DSP. The IF of the KX3 can be 0Hz (direct 
conversion), 8KHz (single conversion), or as you point out, in the case of SSB 
weaver demodulation the 0Hz mark can be placed in the centre of the signal 
passband, then the I/Q signals are passed through the optional roofing low pass 
filter before being unfolded/shifted in the DSP.

The K3 has a double conversion superhet architecture, with an HF first

Combined with digital processing, this creates an analogue of a

possible that it actually implements a final passband centre at 0Hz, and  
then does a final frequency shift to move the centre of the passband to  
the correct audio frequency (i.e. they could have implemented it as a  
single conversion architecture). Selectivity is provided entirely by  
digital processing.

Ron,

Hopefully you have a saved configuration file.
That sounds like a good reason to do an EEINIT and restore the

If you need info on how to do EEINIT, look in the manual under Parameter

If that does not correct it, contact support.

Re: [Elecraft] Receivers?

Matt,

You will not see analog I/Q signals in the K3 - the 2nd mixer's 15kHz 
output feeds an Analog to Digital converter and the I and Q signals only 
exist in the digital realm.
In transmit, the same thing happens in reverse - the mixer sees the 15 
kHz output of a DAC.

KX3 is a pleasant rig if you don't need second ant, many memories accessed
with few clicks, super tight receiver Indeed, KX3 seems more pleasant to
listen to. However, if you care about the strength of SSB on transmit, K3
beats KX3 by a few db due to a better speech processor. So you won't win SSB
contests with KX3. 

K2 seems primitive compared to K3 and KX3 but seems to have a mystical

Re: [Elecraft] Receiver K2, K3, KX3

[Don Wilhelm]

There are many who prefer the analog design and performance of the K2.  
The MDS and BDR of the K3 (K3S) and KX3 are a bit better, but only 
marginally so.
Take the top 20 transceivers in the Sherwood listing and give them a 
critical look.  There will not be a lot of difference between them in 
practical operating terms.  Measurements are one thing, but actual 
operating is another.  Yes, there are pileup situations where a 1 or 2 
dB of difference may make a contact or no contact situation, but those 
are extreme situations not encountered by the typical operator.


The K3 (K3S) and the KX3 are near the top of the Sherwood list, and they 
will be better in extremely crowded band conditions - listening to a DX 
pileup for instance where you can 'saddle up' close to another station 
and not have him bother you (that is what the 2 kHz rating is all about).


As for the K3 vs. the KX3, the K3 provides more "buttons at your 
fingertips" than the KX3 and has a few extra "bells and whistled". My 
recommendation is that if you are serious into contesting and DXing, the 
K3 is the better choice.  If you want portable operation, the KX3 is the 
best choice, and the KX3 will provide a great showing in contesting and 
DXing as well.


Bottom line, the K2, K3, K3S and the KX3 are all contest grade 
transceivers - take your pick based on your preferences and you will not 
be disappointed.

Re: [Elecraft] Nine month rested 2014 K3 now only shows a blank orange screen P3 will not activate.

[Don Wilhelm]

Start with the basics - disconnect everything other than the power and a 
dummy load to the K3.

Then power it on.
If all is well in that basic configuration, then start adding the extra 
things one at a time to find out what is creating the problem.
If the basic K3 still responds with a blank LCD screen, then try an 
EEINIT.  Hopefully you have saved a configuration file so you can 
restore the configuration data after the EEINIT - if not follow the 
calibration steps in the manual to get back to an operational state.


If that does not help, contact Elecraft support.

[Elecraft] K30-Mini link stoped working.

[Brian D. Comer]

I am in the process of setting up a remote station. I have the K30-mini and
the two RRC1258 units with a K3S as the remote.

 

Currently I am on using my LAN, which worked fine on initial setup. In
trying to set up the remote using HRD and the control RRC, I have broken the
system. In returning the settings  to use K30 control the only thing I see
wrong is that the remote RRC settings indicate the K3S is off. I had not
taken a note of this setting when the  system was working but the K3S is on
and I cannot see why the RRC indicating it is off. I have checked all cables
on the K3S and remote RRC. Should the remote RRC1258 be reporting radio ON?

 

73 Brian KF6C.

Re: [Elecraft] K3 M1 Button Corrupt

[Scott]

Don't automatically assume your M1 button is corrupt.  IIRC, I think the 
M1 - M4 buttons can be used for macros or frequency selection.  See the 
K3 manual on specifics.  You may have accidentally set the M1=MENU as a 
macro.  Try overwriting the M1 button with either another macro or 
frequency, whatever you want it to do.  Good luck.

I was running K3 with HRD software and manually entered MENU.  Not sure of
the exact sequence but now the M1 button functions like the MENU button and
returns to the last MENU setting I was looking at.  Toggling again returns
to NORMAL operation.  This is via front panel button or software command.  I
have powered down and up and reloaded all K3 software.  I suspect a hidden
table with button actions that needs to be reset.  Any ideas?

Don,  Good news EE INIT cures the problem.  Bad news I'll be manually
rebuilding my config.
