Re: [Elecraft] New KX3 up & running.

[lstavenhagen]

Well, you get what you pay for is about all I can say there. The Buddipole is
so well thought out and constructed you don't have to replace half of it
with upgrades as soon as you buy it, like some of the cheaper alternatives I
looked at. You're basically done with the credit card the first time around
unless you need extra accessories like the aforementioned whips, and you
don't have to get it out again for a long time. It just works and it stays
together in the field, which for me makes it worth what I paid for it.

The only thing I had to repair was the painters-pole style attachment at the
top of the telescoping mast. It's held on with just a set screw; I had to
remove it and reinstall using hot melt glue and it's been permanent ever
since. That's the only problem I've had.

So yeah you can get other antennas for cheaper, but nothing else I looked at
looked like it could survive throwing around and setup/teardown etc. on a
repeated basis for a long time like the BP. And it's definitely proven
itself to not break or strand me out in the mountains for sure...

Re: [Elecraft] New KX3 up & running.

[lstavenhagen]

Congrats! And on the Buddipole, I'd suggest ordering a set of the long
telescoping whips (the near-10 footers) and just getting that overwith now,
if you don't have them already. The stock short whips work ok on 15 meters
and up, but on 20 meters tuning gets very very sensitive and narrow-banded.
30 and 40 forget it lol.

With the long whips, it's much easier to tune on the lower bands, and 15 and
up they're long enough to form full length dipoles. The performance on the
air is significantly better as well...

But even so, the Buddipole is one of the best ham radio investments you'll
find you've made, next to your Elecraft rigs of course ;)

[Elecraft] KX3 / KXBC3 NiMH Battery Charger and Real-Time Clock

[wickedbeernut]

I have a dumb question ... why doesn't the KX3 support the current month, day
and year in conjunction with the KXBC3?  Is this a limitation of the KX3
firmware or the KXBC3 real-time clock?  I've never heard of a real-time
clock which didn't support the current month, day and year.  Most support
leap year compensation and are valid through at least 2100.

[Elecraft] New KX3 up & running.

[Michael Heit via Elecraft]

I completed the assembly of the KX3 and the 100 watt Amp. Also set up the 
Buddie pole Deluxe and was blown away by the overall quality of all the 
equipment.
Now to get it all tuned up; need to do the temperature compensation for the 
roofing filters,figure out how to get the Heil headset / mic working so when I 
talk it transmits ... the sound in the earphones is great but I cannot get the 
mic to go VOX. No matter how I follow the manual for set up it doesn't seem to 
work. The included Elecraft mic works of course ...
The auto tuner is phenomenal though I haven't yet fired up the amp with its 
auto tuner.
This Friday I'm heading down to Kislof, Alaska for work and plan to take the 
KX3 for its first field test. My main focus will be HF voice; I have to wonder 
if a firmware upgrade in the future may allow digital voice from the KX3? I 
also want to use Ham Radio Deluxe for rig control and other digital operations 
like PSK, RTTY, etc. so now to figure out the cable connections. I've seen a 
number of photo's showing the use of the Signalink USB but cannot understand 
why one would be needed; I have one on my Icom IC7000 so if needed I could 
change the internal links for the KX3. 
Memorial Day will see us heading out to Deadmans Lake and another field test; 
Field Day will see us up on Tower Mountain at Ft. Wainwright, then the big test 
will be in July when we head up above the Arctic Circle on the haul road for 
some real Alaska bush ops ... I'm itching to try out some QRP and see what 
happens. There is a easy access mountain up there that I would love to try SOTA 
too I have to get back into my CW daze and get up to speed. When I use the 
KX3 paddles I hear a ping from the speaker when I get to sending CW; what would 
cause this?
If anyone is interested in follow up reports I'll post them ... photo's too if 
anyone would like to see my "go bag" set up.

Re: [Elecraft] PX3 Anomoly (bug?) on AM

[GRANT YOUNGMAN]

This may be.  I don’t know if this is a bug, or just the way it is.  

The fact is that it is an odd display for the mode.  The P3 by comparison is 
quite “normal” for AM.  It would be more logical to show the presumptive 
equivalent “IF” on either side of the carrier, or (if Elecraft ever implements 
the stub to a sync detector) just one sideband above or below the carrier.  As 
it is, the display is hard to interpret.  It does appear to depict the “audio” 
bandwidth.  For example, if you bring up the lower edge of the green band to 
the carrier it’s clear the effect is just cutting the low frequency audio — 
e.g., you can’t retune the radio to center the bandwidth on the AM signal — it 
jut cuts the lows and renders the thing unintelligible.  Now if there were a 
really good explanation for how to interpret it (and yours may be part of it), 
that would be fine, too.

When the receive bandwidth is NORM'ed, it is symmetric about the carrier.  But 
it ought to stay that way as the bandwidth is increased.  There may be a 
perfectly good reason why it behaves the way it does.  It just isn’t explained 
anywhere.

It also doesn’t explain why it seems at least, that the KX3 needs to be tuned 
slightly off frequency to “center” the signal when the bandwidth is fully 
maximized.

Sounds rational.  It does seem to me that the most logical approach, presuming 
all of this is the case, would be to always pull the Waterfall height from 
EEPROM, cap it when necessary in text decode mode, and otherwise leave it the 
stored value.  That would solve it.

Re: [Elecraft] PX3 Anomoly (bug?) on AM

[Don Wilhelm]

Grant,

It would appear that you are running up against the bandwidth limit of the
KX3 audio when you widen the bandwidth with HiCut.
I don't know what the limits are, but from your observations, it may be 
that the maximum bandwidth is in the vicinity of 6.4kHz.


So if you have 4.2 kHz on one side, you will be restricted to 2.2kHz on 
the low side.

If you back off the high side to 3.1kHz, is the AM response centered?

I am just venturing a guess, the maximum audio bandwidth is not 
specified for the KX3.

"If the bandwidth/shift or Hi/Lo cut is NORMalized, the green bandwidth band on

as you might expect.  It’s symmetrical around the carrier.  If I open up the HI 
setting to max (4.2 KHz) and set the LO to minimum, the green band is offset to the 
high frequency side of the carrier — with the low boundary about 2.2 KHz below the 
carrier, and the high boundary about 4.4 KHz above the carrier.  These points may 
not be exact, but they were roughly measured using the VFO A marker — close enough 
to make the point.  And just using the usual reduction in background hiss to retune 
the carrier, it appears most closely tuned when the VFO is set about 0.9 KHZ above 
the actual carrier frequency, although even then the green band is offset from 
either the actual or tuned carrier freq.

Re: [Elecraft] PX3: Apparent "bug" fw 1.42

[wickedbeernut]

Holding the MENU / LABELS switch toggles between 0 (FN key labels off), 1 (FN
key labels on) and 2 (text decode on).

Tapping the DISP / AVERAGE switch toggles between 0 (spectrum only) and 1
(spectrum + waterfall).

With text decode off, the Waterfall window height range is 20 - 139.

With text decode on, the Waterfall window height range depends on the Text
menu / Txt Font,

  5x7:  20 - 130
7x11:  20 - 100
9x14:  20 - 80

I assume the Text menu / Waterfall value is read from the EEPROM into a
"local variable" at the time the PX3 is powered on.  With text decode on,
the Waterfall local variable is (potentially) "capped" based on the Text
menu / Txt Font.  Note:  This doesn't change the Text menu / Waterfall value
stored in the EEPROM.  For example, if the Text menu / Waterfall value is
139, Text menu / Txt Font is 7x11 and text decode is on,  the Waterfall
local variable is capped at 100.

You're pointing out that if text decode is turned off, the Text menu /
Waterfall value is not restored (i.e., not re-read from the EEPROM).

If you power the PX3 off and on, the Text menu / Waterfall value is re-read
from the EEPROM.  If text decode is off, the Waterfall local variable is not
capped.  The Waterfall local variable is 139.

Paul can address whether the Text menu / Waterfall value can be re-read from
the EEPROM in turning text decode off or possibly maintaining / deriving the
capped Waterfall local variable separately / independently.

the PX3 sits with it’s edges about 3 KHZ above and 3 KHz below the carrier 
frequency as you might expect.  It’s symmetrical around the carrier.  If I open 
up the HI setting to max (4.2 KHz) and set the LO to minimum, the green band is 
offset to the high frequency side of the carrier — with the low boundary about 
2.2 KHz below the carrier, and the high boundary about 4.4 KHz above the 
carrier.  These points may not be exact, but they were roughly measured using 
the VFO A marker — close enough to make the point.  And just using the usual 
reduction in background hiss to retune the carrier, it appears most closely 
tuned when the VFO is set about 0.9 KHZ above the actual carrier frequency, 
although even then the green band is offset from either the actual or tuned 
carrier freq.

So can anyone explain what is going on, and why the PX3 display (and maybe the 
KX3) behavior appears so odd in AM mode.  Must be something I missed somewhere 
along the line.”

Re: [Elecraft] PX3: Apparent "bug" fw 1.42

[Don Wilhelm]

Grant,

The reason it limits the waterfall to 100 in mode 3 is to make more room 
for the text decode.


Why the maximum value does not go back to 139 when you cycle around to 
1) again is not something I can make any statements about.  Perhaps Paul 
S will comment (bug or 'feature').


Finding things of this nature is what the beta version is all about.  
You might want to email Paul directly pauls at you-know-where dot com 
with your report in case he is not monitoring the reflector at this time.

If I then POWER OFF the KX3, and power it back on, the Waterfall height in mode 
(1) RETURNS TO 139.  Until I cycle around the options again …

Re: [Elecraft] Amplitude Modulation on FM.

[Don Wilhelm]

Jack,

What does the FM output look like direct from the K3?
In other words, disconnect the KPA500 and see if the AM problem is still 
present.

That will tell you whether it is a K3 problem or a KPA500 problem.

Do not overlook the possibility that it is RF feedback getting into 
something.  If the problem gets worse with increased power, suspect 
RFI.  Also working into a dummy load should eliminate the possibility of 
RFI.  If RFI is the problem, better common mode chokes on your antenna 
and tighter feedline connections are the tools to attack it.


Also monitor the AC voltage during transmit as well as the output 
voltage of your power supply. If one or both sag substantially, that 
problem should be fixed first - for the AC side, better wiring to the AC 
receptacle (dedicated circuit), and for the power supply output, either 
tighter connections or larger wire, or there could be an internal 
problem in the power supply.

Sure! fldigi will operate on any platform and run just about any mode 
you can imagine.  You wouldn't need MMTTY since fldigi can operate rtty 
in any mode you care to use.  It's even amazingly good at decoding cw.

Re: [Elecraft] Elecraft Centric

The West Valley Amateur Radio Association (using the K6EI call) 
has been running K2s and K3s at field day for at least 5 or 6 
years. We run QRP battery for the entire "contest". We use a 
collection of lead acid batteries in the 100 AH category with 
solar panels as a power supply.


It's really nice using a world-class radio and they help us

[Eric Swartz - WA6HHQ, Elecraft]

Folks,

Lets end this thread now, as it is exceeding our SNR posting limit.

As per my prior post (see my prior email below), its OK to post OT and 
competitive topics if the number of postings in the thread is limited to less 
than 5-10. (Preferably closer to 5 or less).


Also, please do not rely on me to moderate (and end) all threads. I'm frequently 
away from the computer running our daily business and can not reply until much 
later, frequently after a thread has gotten out of control. I ask that everyone 
self moderate, and when they feel they have to keep talking, take the OT thread 
off-list.


Lastly, it is absolutely outside of list guidelines to post what you feel is not 
allowable or preferred for postings here.  As noted in our list guidelines, 
please send concerns of this type to the list moderator (me). I have a very 
thick skin ;-)

Re: [Elecraft] PX3

[Jerry Moore]

I'm a technologist by career. I love the whistles, bells, and eye candy
available. 
When I make my purchases my decisions are based more towards total cost of
ownerships, product usability lifespan, durability..etc.. 
This typically means my dollars don't normally go to the newest flashy toy
but does go to what I perceive to be the best bang for the buck. 
In the case of my Ham Radio Equipment I push to more easily
supportable/upgradable/maintainable gear. 

Different systems illustrate weaknesses differently due to design intent and
planned use. This means that EVERY SYSTEM is a compromise when used outside
of it's designed use. 
A great illustration of this is commercial communications gear vs military
avionics gear. The intended use is different which drastically changes the
design. 
I didn't purchase my Elecraft K3S because it was the latest and greatest
technology. I purchased it because it met and  greatly exceeded my intended
use based on its' design.

Upgradable
Open box type construction for repairs/troubleshooting.
Modular
Fanatic support - both community and company, in a language I natively
understand
Capabilities and features that require a skilled operator to fully
understand, leverage, and get the most from, WHILE, still being usable by a
novice (the DSP in my K3S is phenomenal, 4 different settings can be mixed
to pull signals or hide interference or ..etc..)..  

For the premium paid I've not found another radio even close to my K3s. I
CAN find radios with the same or even better ,
however, I've not found a package as capable..

Re: [Elecraft] PX3

[Doug Person via Elecraft]

Honestly, the size of the spectral display isn't as important as the 
fact that it is extremely effective.  It works.  It's all in one small 
box.  The K3/K3s - P3 and KX3/PX3 are wonderful bits of technology.  But 
their U/I's remain a fine examples of the best of 20th century design.  
Large, full color, capacitive-touch, fully reconfigurable displays are 
becoming more pervasive every day. Refrigerators have them.  Top of the 
line test equipment, remote controls on the coffee table, car dash 
boards with two or more displays, it goes on and on.


The IC-7300 is Icom's first shot at full-color touch technology. They 
pioneered the full color display and were very successful at it.  It's 
pretty clear that the Big Three have recognized the paradigm shift.  In 
a few short years everything else will look dated - because it will be.

Re: [Elecraft] How to get K3/0 data into a logging program

[Fred Jensen]

Don't know about an iMac, I have studiously avoided anything whose name 
begins with a lower case "i", but ...


I run W7RN remotely with my K3 and the RRC 1258Mk2 and use N1MM in 
contests on a PC.  Here's my recipe:


1.  Serial cable from control K3 to back of RRC box.  This establishes 
remote control.


2.  USB from RRC front panel connector to PC.  When connected, the RRC 
box creates 4 virtual COM ports -- COM0, COM1, COM2, and COMExtra.  In 
device mgr, they will have a "real" COM port assigned in parentheses.


3.  Locate the virtual port COM1, and note the "real" port in parens. 
That's the port # that goes into N1MM.


The frequency data comes from the remote K3, not my local control K3.

So, if you can translate that into Apple-ese, it should work for you.

Re: [Elecraft] K3: internal 2m transverter offset problem

[GRANT YOUNGMAN]

Are you on the latest firmware rev level in the 2M module?  I thought I was and 
missed an update somewhere along the way.

I recently pulled my 2M module and sent it to Elecraft because one of the two 
crystals was marginal, and it was dead from 146-148 MHz.  I got back their 
evaluation and, along with the crystal replacement, I was (very sheepishly, I 
might add) informed that I did not have the latest firmware which is needed to 
enable REFLOCK in the 2M module …  This sounds (sadly) familiar and might be 
the issue …

[Elecraft] K3: internal 2m transverter offset problem

[Jim Spears]

I have K3 s/n 6866 with internal 2m transverter.  I have not paid much
attention to the transverter for a while but I noticed something odd a
couple days ago and have not been able to do anything about it.

 

If I set the Elecraft XG3 to 144.100 and feed its output into the
transverter input connector, the signal shows up at 144.095, 5 KHz low.  

 

If I tell this K3 to output 2m rf on 144.100, I hear the signal at 144.015
on K3 s/n 6425 which has an external 2m transverter.

 

I first noticed this when monitoring a local 2m FM repeater and could not
copy its output until I tuned 5 KHz low.

 

The K3 does have an external 10 MHz clock and CONFIG REF CAL has the
blinking asterisk.  FWIW, the value shown is 49.379.962.

 

CONFIG XV OFS is 144  -0.08 and cannot be changed, when I go to adjust it
REFLOCK appears.

 

What's up Doc?

Re: [Elecraft] Elecraft Centric

[lstavenhagen]

Well I do have to say, though, that my "K3 plus" and K3s both are very
respectable /p rigs, though. Both are the 10 watt versions and will actually
run for a couple hours pretty well on even a 9AH AGM battery.

Yeah, a solar panel or a larger batt would be required for longer than that
or a lot of QSO's at 10-12 watts, but to me it's pretty cool that I can
operate the highest performing rig on the market (or close to it) off the
tailgate of my pickup in the mountains or hills around where I live. 

I'd have to go to the bank (with a gun) to fund buying their nearest
competitor and I don't think I'd dare try to haul it out to the mountains,
even in my nice Pelican case. 

Anyway, to make this more on the topic of competitor analysis - it'll be
interesting to see what Elecraft comes up with if they decide there's a need
to respond to the 7300. I posted elsewhere about that, where I think it may
scratch an itch out there where the KX3 doesn't scratch it quite as well. 

But to me, even a K3(s) is a worthy competitor in /p, though it's kind of a
sledge hammer for portable ops with far far more RX performance that you'd
typically need.

73,
LS
W5QD

[Elecraft] A helpful review...

There are a pair of untrue assumptions in there.

1) Assumes that someone here, who doesn't want to transact discussions
about Flex products on the Elecraft reflector, cannot possibly hear about
Flex anywhere else. That if Flex information is not brought up on the
Elecraft reflector, the "good news" on Flex products will never be heard.

Personally, I've been on the Flex reflector since the very beginnings of
that product line. I can tell you an awful lot about where Flex is, what
the problems and improvements are. I have been on the cusp of a Flex
purchase for years. I just have a list that I'm waiting for them to invent
their way out of. A couple of those items need faster technology at lower
cost, which will get here, sometime. I just won't discuss it here on the
Elecraft Reflector.

It is also abundantly clear that I know more about Flex products than
trolls that have come on here hyping Flex just to see if they can get under
someone's skin. But I will not discuss issues about Flex products on the
Elecraft reflector. From where I sit, overall Elecraft reflector commentary
on Flex is fair-to-poor, sometimes outright inaccurate, but so what. It's
the *Elecraft* reflector. I expect accuracy on Flex products on the *Flex*
reflector.

Besides the Flex reflector, I get my Flex information from actual Flex
owners, and from the incessant joyful no-holds-barred all-rigs-comparison
commentary among PVRC club members, who have actually owned or do still own
the rigs under discussion. This, along with the opportunity to actually
operate other brands, beats out any other source of information hands down.

This reflector (Elecraft) ranks way up there in comparison to other
brand-centric reflectors. But it's up there because people on the Elecraft
reflector get outstanding help on Elecraft products, some from individuals
like W3FPR, who are off-scale high helpful on the
did-you-get-quick-and-accurate-information-that-helped-you-out scale.
Commentary on the world at large is not what drives up the Elecraft
reflector numbers.

2) It's not at all that I don't want to hear about "other new and exciting
developments". I'd just rather keep it to Elecraft here. I have really good
sources of everything else *elsewhere*. And I really do not trust any
information from folks that are just trying to stir up controversy to get
some yuks. You know who you are.

If I want to argue about rigs, I'll go join the long-running all-smiles
friendly rig-comparison food fight with some of my great lifetime friends
at PVRC.

Re: [Elecraft] Elecraft Centric

Yes. In any group where you're paying attention, you tend to figure out 
who the heavy hitters are, who provide the needed BS filters. W3FPR, 
N7WS, K2AV, W4TV, AB7E, W4NZ, W9AC, GM3SEK, W0YK, NY9H, N6XI are a few 
members of this group who come to mind.

(Elecraft or other).

Re: [Elecraft] [OT] SteppIR antenna summary

[Edward R Cole]

After posting my query on how Steppir handles cold/icy wx, I received 
a reply from Michael, k5wmg, suggesting I might look at the Tennadyne 
T8 log-periodic.


I had looked at the log-periodic in years past  for VHF and passed at 
they were quite big for minimal gain.  But the typical 3-element HF 
yagi has 6-dB gain in free space so the 5.8 dB gain of the 8-element 
T8 on 18-foot boom would be comparable with the plus that a tuner 
would not likely be needed (besides I have a manual tuner should it be needed).


What is a deciding factor for me is $788 vs over $2K for the basic 
3-element Steppir (not including optional accessories).


I briefly looked at the T11 ($910) which covers 13.5-54 MHz but the 
extra cost and added elements on 24-foot boom would not make sense 
since I already have a 6-element 6m yagi and a fixed pointed 3-element 6m yagi.


Probably will not do anything until the elderly TH3mk4 looses an 
element or a trap goes bad.

Re: [Elecraft] High Tx IMD with new K3s/10

one test that surprised me was the high Tx IMD levels.


Some things to check.  What power supply voltage?  Was it a matched 
load?  Distortion increases with most power amplifiers (including the 
output stage of a rig) with low power supply voltage and with a 
mis-matched output.


And, as was suggested, was the test gear overdriven?

I bought a PX3. Much smaller and lighter, integrates nicely.

Re: [Elecraft] Elecraft Centric

[John]

Phil - yes, in much the same way as the K3S is not a SOTA rig :-)
I have a KX3 and also an IC-7300, and I don’t see either as competition
for one another - I will keep both.
Interestingly, the current draw on RX on the IC-7300 is amazingly low
taking into consideration the multi-functional large color display. It draws
only 900 ma, which is about half the current draw of the miniature IC-7000.
Of course the KX3 is the champion when current draw is the main
criteria.
So yes, I see myself using my KX3 for SOTA and other ultra light portable 
operations, but I will take my IC-7300 to operate from park benches, camping
and holiday style Dxpeditions.

Joe,

Crucial difference is that the KX3 system is
modular and the barefoot KX3 can be used very
effectively battery operated for SOTA, camping and
the like. I suspect the IC-7300 was not designed
for power efficiency :-)

So I see them as a very different class of rig.
