Re: [Elecraft] k2 kit progress - Woops! Did I really do that?

[Don Wilhelm]

Don,

Yes, email pa...@elecraft.com, or since you have the part number, you 
can contact sales sal...@elecraft.com or phone them at 831-763-4211 to 
order a replacement.


To remove it, cut the plastic or otherwise push it off the pins, and 
then remove the pins one at a time unless you have really good 
desoldering tools.

Re: [Elecraft] [K3] factory upgrade to K3(s)

[ab2tc]

Hi all,

There is a bit of misinformation in this thread. The new synthesizer does
not make any difference to the noise floor in the absence of strong nearby
signals. This is how noise floor is usually measured. What it does is
improving the reciprocal mixing of nearby signals and the phase noise on
transmit. This improvement is significant. But the basic sensitivity of the
receiver (noise floor) is not affected.

AB2TC - Knut

I'm certain that some charlatan preying on high futility nuts would be 
quite happy to lighten his bank account by at least as much as he paid 
for the KPA500. These products provide no benefit to audio consumers, 
and they would provide no benefit in a ham station. Their only function 
is to transfer money from the buyer to the seller.


None of what's being discussed here should be a problem, and the easiest 
ways to minimize the symptoms are 1) to simply beef up the wiring 
between the power amp and the distro panel, or 2) shorten the wiring, or 
3) provide a breaker dedicated to the shack. A single 15A circuit should 
run all the RADIO equipment in the shack where the power amp is a 
KPA500. Obviously, a 20A circuit provides more margin, bigger copper and 
shorter copper reduce IR drop.


For the printer, as others have noted, the IR drop between it and the 
breaker panel for the turn-on surge, so bigger copper for that part of 
the run would also have to be replaced.


And yes, a solar array syncing could easily be the cause of that 
9AM-10AM event reported by NW6V.

[Elecraft] K3s

[Rose]

FWIW, my embroidery software allows me to reproduce "K3s" in the ratio
that's used by Elecraft.

Re: [Elecraft] [K3] factory upgrade to K3(s)

[Don Wilhelm]

Skip,

Maybe, but that is not within the Elecraft policy of not releasing a new 
model with every upgrade mod like other manufacturers do.
The K3S is more than an upgraded K3 (for example, the RF Board cannot be 
changed in the K3), but it is similar to the change in the K2 that 
happened at SN 3000.


Hindsight says it should have been called the K4 or something similar.

Eric is likely to shut down this thread soon!  Too many posts, and here 
I am adding to the count.

transmit and receive phase noise.

That is far too simplistic. Anyone's personal definition of "the
better synthesizer" will depend on what range of frequency offsets
is more important for their particular type of operating.

For HF CW in particular, phase noise at small frequency offsets is
of paramount importance and I wouldn't argue with Don's report of "a
huge improvement in both transmit and receive phase noise" - but
*only* in that specific context. There are also several other
advantages that are relevant to high-performance HF CW that could
also justify upgrading to the KSYN3A.

At close frequency offsets from the carrier, the KSYN3A does indeed
offer a large reduction in phase noise compared with the KSYN3
(which itself was already good). But at wider frequency offsets,
that situation reverses. According to the ARRL review [1], at all
offsets beyond about 6kHz, the older KSYN3 continues to have a lower
noise floor than the newer KSYN3A "upgrade".

Performance at wider frequency offsets, 10-100kHz and beyond, is of
much greater importance in VHF-UHF contesting. This due to a
combination of factors. The strongest signals at VHF-UHF are often
much stronger than on HF, due to the use of high-gain beam antennas;
and also the weakest signals are *always* much, much weaker due to
the lower levels of natural background noise. These two features
stretch the requirement for dynamic range on VHF-UHF far beyond
those for which most HF transceivers are designed.

Anyone transmitting wideband phase noise has a much greater risk of
raising the noise floor of many other stations across the whole
contesting segment of the VHF or UHF band. Running the numbers
reveals that anyone aiming to be a Big Gun in VHF contests has a
responsibility to keep their wideband transmitted noise floor below
about -130dBc/Hz at frequency offsets of 50kHz and more [2]. This
can be a major engineering challenge, and the performance of the
transceiver is almost always the most important building block.

The KSYN3A just about meets the -130dBc/Hz noise floor target at
frequency offsets of 10kHz or more... but according to the ARRL
review [1] the older KSYN3 achieves it much more comfortably, with
10-15dB to spare.

I have both a K3S and a very early-model K3. The K3S (with the
KSYN3A, of course) is used for HF contesting where smaller frequency
offsets are important. Meanwhile the old K3 is now used as a
transverter driver for 144MHz and above - and for that particular
purpose there are very good reasons *not* to replace the original
KSYN3.

Sorry, this talk is accessible only to RSGB members, but in a few

G8DOH runs the numbers to demonstrate that the  -130dBc/Hz target
for transmitted phase noise is necessary to avoid raising the noise
floor of other stations many kilometres away, and also many tens to
hundreds of kHz away across the band, whenever their high-gain beams
happen to be pointed at each other.

That calculation assumes the UK transmitter power limit of 400W PEP
output. For the US power limit of 1500W output, keeping all other
assumptions the same, the target for transmitted noise floor would
need to be better than -135dBc/Hz. The older KSYN3 can still meet
that more stringent target but the KSYN3A probably cannot.

Exactly Don.  Thanks for that comment.  That's what the boys at Elecraft 
recommended when K3S was first announced and we had a field day (pun) with 
remarks about plural, etc when guys tried to match the logo.  You'll notice 
that Wayne always uses K3S now on this reflector.  I am still trying to figure 
out what the K3(s), the K3[s] and K3*s guys are trying to say.  

Don't try to replicate the K3S marketing logo as you can't do it with the font 
here on the reflector.  Please just use K3S.

Grant,

I always use "K3S" and "K3", and add a lower case "s" for plural.
If you look at the logo, yes, the trailing "S" is smaller than the "K3", 
but not small enough to be lower case (1/2 the height of the caps).

Re: [Elecraft] KPOD

[Jim N7US]

I had a remote tuning knob when I had a Ten-Tec Omni VI+ several years ago, so 
I was glad to get a K-Pod when it was introduced.  I like it very much for the 
reasons already mentioned, especially the ergonomic benefit of having it next 
to my keyboard.

When I had my K3, prior to getting a K3S, I had a rubber Ten-Tec trim ring 
around the VFO A knob.  Then I replaced both VFO knobs with the 
now-discontinued, weighted knobs from 73CNC.  I'm using the stock knobs on my 
K3S but have the fancy 73CNC knob with the dimple on ball bearings on the 
K-Pod, and life is good!  My suggestion is to be on the lookout for a 73CNC VFO 
A knob for your K-Pod.

73, Jim N7US

-Original Message-


Love the Kpod.  Even though I was very comfy with the RIT even with the tiny 
knob, I got very used to it.  But during a contest it required reaching across 
the keyboardand taking my right hand away from the keyboard.  The Kpod sits 
right next to the number pad.  I only ever use it for RIT, not direct vfo 
tuning.  I have CAT commandsin the n1mm messages for cw to clear the RIT after 
the F3 tu msg and also in the CQ msg.  Right next to the number pad is close to 
the enter key on the right of thekeyboard for serial number contests.
I don't do a lot of phone, only twice a year for contesting, but I have macros 
in F1 thru F4 for keying the M1 thru M4 buttons for the dvk.  Its a great 
accessory.

Re: [Elecraft] [K3] factory upgrade to K3(s)

[Ian White]

>A big reduction in receiver noise floor and a huge improvement in
both
>transmit and receive phase noise. 

That is far too simplistic. Anyone's personal definition of "the
better synthesizer" will depend on what range of frequency offsets
is more important for their particular type of operating.

For HF CW in particular, phase noise at small frequency offsets is
of paramount importance and I wouldn't argue with Don's report of "a
huge improvement in both transmit and receive phase noise" - but
*only* in that specific context. There are also several other
advantages that are relevant to high-performance HF CW that could
also justify upgrading to the KSYN3A. 

At close frequency offsets from the carrier, the KSYN3A does indeed
offer a large reduction in phase noise compared with the KSYN3
(which itself was already good). But at wider frequency offsets,
that situation reverses. According to the ARRL review [1], at all
offsets beyond about 6kHz, the older KSYN3 continues to have a lower
noise floor than the newer KSYN3A "upgrade".

Performance at wider frequency offsets, 10-100kHz and beyond, is of
much greater importance in VHF-UHF contesting. This due to a
combination of factors. The strongest signals at VHF-UHF are often
much stronger than on HF, due to the use of high-gain beam antennas;
and also the weakest signals are *always* much, much weaker due to
the lower levels of natural background noise. These two features
stretch the requirement for dynamic range on VHF-UHF far beyond
those for which most HF transceivers are designed. 

Anyone transmitting wideband phase noise has a much greater risk of
raising the noise floor of many other stations across the whole
contesting segment of the VHF or UHF band. Running the numbers
reveals that anyone aiming to be a Big Gun in VHF contests has a
responsibility to keep their wideband transmitted noise floor below
about -130dBc/Hz at frequency offsets of 50kHz and more [2]. This
can be a major engineering challenge, and the performance of the
transceiver is almost always the most important building block. 

The KSYN3A just about meets the -130dBc/Hz noise floor target at
frequency offsets of 10kHz or more... but according to the ARRL
review [1] the older KSYN3 achieves it much more comfortably, with
10-15dB to spare.

I have both a K3S and a very early-model K3. The K3S (with the
KSYN3A, of course) is used for HF contesting where smaller frequency
offsets are important. Meanwhile the old K3 is now used as a
transverter driver for 144MHz and above - and for that particular
purpose there are very good reasons *not* to replace the original
KSYN3.

Sorry, this talk is accessible only to RSGB members, but in a few
words...

G8DOH runs the numbers to demonstrate that the  -130dBc/Hz target
for transmitted phase noise is necessary to avoid raising the noise
floor of other stations many kilometres away, and also many tens to
hundreds of kHz away across the band, whenever their high-gain beams
happen to be pointed at each other. 

That calculation assumes the UK transmitter power limit of 400W PEP
output. For the US power limit of 1500W output, keeping all other
assumptions the same, the target for transmitted noise floor would
need to be better than -135dBc/Hz. The older KSYN3 can still meet
that more stringent target but the KSYN3A probably cannot.

Re: [Elecraft] [K3] factory upgrade to K3(s)

[Bill Frantz]

(Note: K3s refers to multiple K3 radios. K3S refers to a single 
K3S radio. K3Ss or K3Ses refers to multiple K3S radios. I'm 
sorry if you are reading the note on a monocase system like RTTY.)


Many of us have installed the new synthesizers in our K3s. For 
example, #6299 has the new synthesizers, and the rest of the 
available K3S goodies. One clear advantage of Elecraft radios is 
that they can be upgraded, and they don't even need a trip back 
to the factory to do it.

Our setup was in, unfortunately, a fairly high noise area. I was working 20 CW. The 
noise level was S3, with times reaching S6. I believe, "normal" would be closer 
to S1. And, of course, lots of signals all over the board signal strength wise. Many of 
them very strong (10 to 20 over 9!).

In the last few months I've noticed that every morning, between roughly

from the KPA500. The pulsing events last perhaps 30 seconds to a minute,
and may happen more than once.

Yes, this ceases if the power cord is out or the power switch on the rear

To me, guessing, it sounds like something connected to the main AC feed is

Re: [Elecraft] KPA500 Noise While Off

[Bob McGraw K4TAX]

It would seem prudent to install a recording power line monitor.   This would 
give a clue if further line conditioning would be advantageous.  Your power 
company may be able to assist in this matter.

Re: [Elecraft] [K3] factory upgrade to K3(s)

[Grant Youngman]

As far as I know, the new DSP board has NOT been made available. (I've asked 
about it time or two).  Also the main 4-layer RF board has never been listed 
for upgrade,   Which is a shame, on both.  

I understand the main board — you would have to essentially re-kit the K3 to 
replace it, and then build the radio again.  For many of us who built our K3 
radios to begin with, it would be a couple day’s work.  A lot of folks would 
have sent their radios back to get it installed, and Elecraft would have spent 
all their time tearing down and rebuilding k3s(or building a K3 over again from 
a bag of boards)  instead of building K3(s)s .. How the heck do you 
differentiate between plurals with this radio :-) In any case, I understand 
(sort-of) why the new main board wasn’t an offered upgrade option.  But I’ll 
still throw in my vote … be happy to buy one.

I guess Elecraft needs to maintain some differentiation between versions.

My own K3 is updated with all of the new available options (and historical 
updates) except for the new RF/tuner modules.  I don’t really feel “left out” 
or “2nd class” (at least not for that reason) without a K3S.

Re: [Elecraft] KPA500 Noise While Off

[Chris R. NW6V]

I may be wrong, but that may not be what Dick, WM6G, is referring to.

I've had a KPA500 for quite some time, so I have an idea of what
constitutes "normal."

In the last few months I've noticed that every morning, between roughly
9-10 AM, I hear brief 1-5 second pulsations of easily audible hum emanating
from the KPA500. The pulsing events last perhaps 30 seconds to a minute,
and may happen more than once.

Yes, this ceases if the power cord is out or the power switch on the rear
is OFF. But again, it is brief-lived when it occurs, and it's new.

To me, guessing, it sounds like something connected to the main AC feed is
coming up out of phase, then finally syncing, after which the hum stops.

A neighbor's solar array? I have no idea as of this point.

Re: [Elecraft] KPA500 Noise While Off

Yes that is the magnetization current of the transformer core. 
Doesn't happen when powered up at the zero voltage crossing point. 

One person advised to always turn on equipment at the zero crossing point.  
Seems like a good idea.  Now if I could only get my finger timed correctly to 
do this.

Re: [Elecraft] KPA500 Noise While Off

[hawley, charles j jr]

I’ve only noticed a thump with a piece of equipment which has a power supply 
when it turns on at a line voltage peak. On the occasion that it turns on at a 
line voltage zero crossing, it makes no noise at all.

 It is if equipment in your shack is not properly bonded together, and to
 house grounds that are also properly bonded together. Study N0AX's
 recent ARRL book on the topic, to which I contributed, or the slides for
 a tutorial talk I've done at several hamfests.

Re: [Elecraft] KPA500 Noise While Off

[Bob McGraw K4TAX]

Seems that the AC line supplying the equipment has a rather high impedance thus 
allowing the voltage to suddenly drop under the dynamic load and then surge to 
a higher than normal value. 

A dedicated 120V and/or 240V service should be considered for the station 
power. 

Laser printers do draw considerable power when they start. 

Bob, K4TAX

Re: [Elecraft] How to change K3 COM port to a high number (to avoid N1MM/u2R problem)

[Erik Basilier]

The com ports used for physical control of the radios are normally set up
when I first put a K3 into operation. The MicroHAM router deals with
additional com ports that are not physical but serve to provide
communications between pieces of software within the computer. When choosing
those com ports, I avoid the com port numbers already in use for radio
control, as well as any others that I might find to be in use by looking at
Device Manager.  If the MicroHAM router can do anything to change the radio
control physical com ports, I have missed it. Thanks for your input, and
also thanks to others who have replied to my question. Exhausted after FD, I
will need some time to recover before considering each piece of advice and
otherwise looking at this issue again.

Doesn't the MicroHAM router control the com ports?  You should be able to
set it to anything you want in the router. I have had no issues using Com 1,
2 and 3 with Writelog.

I run two K3 radios with MicroHAM u2R for SO2R in N1MMplus.
It has been working, but occasionally I get a message about COM port
conflicts, about the two COM ports that are used to control the radios, and
this causes problems during a contest such as tomorrow

I have spent some time looking for the source of conflict, but don't see
those two COM port numbers used by anything else in Device Manager, even
when using "show hidden devices". When I set up everything related to N1MM,
and the u2R I totally avoided using those two COM ports that are used for
the radios. I never get the errors when just running the radios without
N1MM/u2R. I don't remember any such error from long ago when I was using
N1MM without SO2R. I sought advice on a computer forum and a Microsoft
employee advised me to try using high port numbers such as 25 or higher for
my applications, as any "hidden" usage in Windows would be unlikely to use a
high number. No conflicts are reported for the numbers I use for N1MM and
u2R, so it seems meaningless to change those to high numbers. It seems I
need to try high COM port numbers for communicating with the radios. How can
I do that? Using the Elecraft FTDI adapters.

[Elecraft] An OCD thought about the KAT500

[Michael Blake]

I received and completed my KAT500k this morning and I must say it is quite a 
tuner.  Very nice indeed. Very capable.

As I integrated it into my K-Line station (K3s, P3 with TX Mon, SP3, KAT500) I 
immediately noticed that the KAT500 does not have the same height feet on it as 
any other cabinet in the K-Line.  Whatever it is placed next to it sits a bit 
over 1/8” lower.

I realize that it probably does match the W2 wattmeter but with four other SWR 
measuring devices (K3s, P3/TX Mon, KPA500, KAT500) I really didn’t plan to buy 
one of those just to even up the cabinets :).

So for us OCD folks maybe it would be possible to include both height feet in 
the kit so that it could match the rest of the product line when desired.

If you take a look at my picture on QRZ.com  you can clearly 
see how it throws everything out of balance :)

Very 73 - Mike - K9JRI

[Elecraft] FS: KX3/PX3 QRP Station & Peripherals

[James Bennett]

A recent re-build of my office / radio shack due to hardwood flooring 
installation brought me to the realization that I simply have more equipment 
than I really need, or use! So, I am (sadly) pairing down the station to two 
rigs, my K3/P3 and a new KX2/KXPA100. That means there is some equipment to be 
sold. EVERYTHING listed below works perfectly. I am the original owner/builder 
of all items, and they’ve never been in a smoking environment. Original sales 
receipts for the Elecraft equipment is included. The KX3/PX3 has never been “in 
the field”, other than a mini-DXpedition to the southern Philippines in 2017 as 
DU8/W6JHB. And that wasn’t really “in the field”, as all operating was done 
inside air conditioned buildings!

Items will be shipped at my expense to the lower 48 states - no foreign sales - 
sorry. I will accept personal check (two weeks to clear before shipping), but I 
prefer PayPal, with payment going to “my call” at arrl dot net. 

KX3/PX3 Station:
  KX3 #4359 160-6 meter all mode 15-watt HF transceiver, with manuals. Current 
firmware installed.
  PX3 #1234 (yes that’s the real number!) Panadapter for KX3, with owner’s 
manual. Current firmware installed.
  KXAT3  Internal antenna “tuner”
  KXBC3 Internal NiMH charger with Real-Time Clock (batteries NOT included)
  KX3-PCKT accessory cable set
  Gemsproducts SideKX end panels and clear poly-carbonate cover for both KX3 
and PX3 (original Elecraft side panels included)
  Pro Audio Engineering Heatsink (original Elecraft back panel/heatsink 
included)
  Pro Audio Engineering Kx133 110/220v power supply
  Fred Cady KX3 Book

PRICE FOR ALL ABOVE: $1,700 …….   If bought new today, these items (in kit 
form) would run $2,158 plus shipping and possibly tax. 
Sold as complete station - I do not want to piece it out.

Also for sale:

Elecraft T1 20-watt antenna tuner: $110

Elecraft XG3 & KXUSB cable: RF Signal Source: $195

Oak Hills Research WM2 QRP watt meter: $100

Please contact me off-list if you are interested. “my call” at arrl dot net

Re: [Elecraft] KPA500 Noise While Off

[Ken Winterling]

Dick,

The KPA500 has a power supply switch on the rear panel adjacent to the
socket for the power cord.   When you press the OFF button on the front
panel the control circuitry is still active.  This permits software to
remotely power up the amp.  If you turn off that rear switch all power is
removed from the amp; the same as pulling the plug from the wall socket.

Re: [Elecraft] KPA500 Noise While Off

[Bob McGraw K4TAX]

Although the front panel switch is OFF, the control circuit of the power 
supply remains ON as long as the rear power switch is ON or power is 
applied.  It is normal to hear a small amount of hum from the power 
transformer and the left rear of the cabinet to be slightly warm.  See 
page 14 of the KPA500 manual for more detail.

[Elecraft] KPA500 Noise While Off

[Richard Wade]

Yesterday I heard a faint "hum" in my shack but all of my gear was off.  It
sounded like possibly a fan running or power supply noise.  I did a very
scientific test of the sound source by putting my ear to each piece of
equipment in my shack and soon found that the noise was coming from my
KPA500!  The amplifier was off but was still connected to the shack ac
power.  I then removed the power cord from the KPA500 and the noise
disappeared.  Does anyone have any idea how this could  happen?

By way of further background, I have been dealing with QRN from a recently
installed solar system.  I have traced the source of that noise to the
solar system by confirming that the QRN goes away when the solar system is
turned off while running my K3s on battery power.

If I had to venture a guess, I would say that somehow the unpowered KPA500
was picking up noise on the shack wiring.  Very strange. Is that possible??

Re: [Elecraft] [K3] factory upgrade to K3(s)

[Mark E. Musick]

Ronnie and Don,
There is no need to pop the cover to check the K3 to see if it has the new 
synthesizer. It says on the Elecraft website they started installing the new 
synthesizer in the K3 starting with serial number 8801. If your K3 serial 
number is 8801 or higher, you have the new synthesizer.

Mark, WB9CIF

The latest K3 builds included the new synthesizers.  Open the top cover and

new ones.
The new synthesizers make a big improvement - If I recall it is an 8 to

Re: [Elecraft] [K3] factory upgrade to K3(s)

[Dave Cole (NK7Z)]

With all the talk about the old and new synthesizers, I dug out my old 
screen captures of some tests I did showing P3 captures as the 
synthesizers were changed from old to new, in two radios, one looking at 
the P3 for changes.  See:


https://www.nk7z.net/k3/

The images are of my P3, showing another radio with both with the old 
synthesizer, then with one radio upgraded, then both radios upgraded. 
There is a very visible change for the better using the new synthesizers.


73s and thanks,
Dave

Re: [Elecraft] Issues Using K3S nternal Sound Card for FT8

Thanks for the suggestions.  Unfortunately none of them worked.

Since I want to work the Baker Island DXPedition, I switched back to the 
SIgnaLink interface, and everything works perfectly.

Guess I will work on it later.

[Elecraft] Oddity with Kenwood TS990

[Paul Baldock]

I thought the problem I just posted was interesting but did not 
really matter, however I just discovered something more significant. 
The MAIN and SUB VFO's can be on the same band and have a similar problem.


If the frequency is different by more than one KPA-1500 ATU segment 
and you are TXing on the SUB frequency, then the ATU will switch 
continuously back and forth the between the two frequencies. This 
means you can't go split (TXing on the SUB) when using the ATU, by 
more than 10KHz on 160M and 20KHz on 80M-12M.


- Paul  KW7Y






My KPA1500 is "sniffing" the frequency that is being sent by the 
TS990 to my logging program.


I was working split on 40M, TXing on the TS990 Sub Frequency 
and  RXing on the TS990 Main frequency. All worked well.


After the QSO I switched the TS990 Main frequency to 20M to listen 
around. The Main is still selected RX and the Sub still selected for 
TX. I heard the KPA1500 going click click click ..;, looked over and 
saw it going back and forth between 20M and 40M; it couldn't decide 
which band to be on. I would have expected the KP1500 to go to the TX 
band and stay there.


I will try turning off the logging program, add a wire to the XVR 
connector for TXD,  and set the KP1500 to poll the TS990 and see what 
happens then.

Re: [Elecraft] KX3 - Strange Behaviour

[Brian Hunt]

Did you have the NB on?  I've noticed on my KX2 (similar h/w and firmware) that 
using the NB with very strong signals close by will create all sorts of 
artifacts like CW being sent using a highly damped bell. Turn off the NB and 
it's clean as a whistle. HTH

Re: [Elecraft] [K3] factory upgrade to K3(s)

Chuck,

A big reduction in receiver noise floor and a huge improvement in both 
transmit and receive phase noise.  It is like getting a new transceiver.


If you are strictly a casual operator, those qualities may not be 
important to you, but if you are a DX'er or a contester, or otherwise 
operate in crowded band condition, those things should be important to you.

On the other hand, just changing the synthesizer(s) in the K3 makes a huge
difference and is worth doing. Yes, there are plenty of other nice things

Re: [Elecraft] [K3] factory upgrade to K3(s)

[David F. Reed]

I upgraded by K3 to as close to a K3S as I could; I am very happy with 
it.  Is it a K3S? No, but in the ways that matter to me, it is... I feel 
like it cost me less than selling it and buying a K3S would have, and 
will be worth a bit more when I finally sell it.


As for not exchanging yours after a month, it is not COSTCO... How far 
in advance should they stop selling one product before its replacement 
comes out? How far back should they be willing to do an exchange? I fear 
there are no good answers for a small company that needs some cash flow 
to keep progressing during development; nailing down exact dates for FCC 
acceptance and supplier readiness and so on can be difficult, and 
besides, I have learned to measure the goodness of my purchase decisions 
based on "was it a good decision based on all information available to 
me at the time?".  If so, relax, be happy.


Anyway Ronnie, you might look into upgrading, I have been happy doing it.

Robert -

I had mine done last year. The K3 cannot be fully upgraded to a K3s,
and what all 'can' be done depends on such things as: Do you already
have the new synthesizer board or boards, depending on having the sub
receiver or not. And, are there options that you do not want.

Perusing the Elecraft website will give you a pretty good idea, and if
you have questions just email support and discuss what you have, what
they can do, and what you want... then they can give you a much better
idea than I can.

I already had the new synths in my K3, and the upgrades I opted for
came in at close to, but somewhat under $1000 including shipping.

Best of luck,

Re: [Elecraft] [K3] factory upgrade to K3(s)

[Victor Rosenthal 4X6GP]

On the other hand, just changing the synthesizer(s) in the K3 makes a 
huge difference and is worth doing. Yes, there are plenty of other nice 
things about the K3S, but I already had a good external preamp and no 
need for a USB port.

Re: [Elecraft] [K3] factory upgrade to K3(s)

[hawley, charles j jr]

I bought a new K3s this year and moved the filters from the K3 to it and the 
2.7KHz filters to the K3. Also moved the DVR to the K3s. Then I upgraded, did, 
all the mods to the K3 that kits were available for including the USB update. 
However, I did not upgrade the synthesizers. I used the K3 and the K3s the way 
I used them and feel more than satisfied with the K3 as a spare rig. My K3 is a 
4xxx serial number from about 2010 and has the gold plated connectors.
I did not buy the tuner for the K3s because I never used the one in the K3. I 
didn’t move it over either. The new tuner is improved and would just buy it if 
I felt I needed one.
There are a few things that cannot be improved on the K3, like the audio amp, 
but I don’t seem to miss them when using it.

[Elecraft] KPA1500 Client/Server Software

[Paul Christensen]

Is there any news from Elecraft or a third-party developer concerning
KPA1500 client/server software?  Some of us, and likely many more ops, need
the ability to control the amp from a remote desktop without the need of
desktop replication software like TeamViewer and VNC.   N4CC and I share his
KPA1500 at a remote and while the KPA1500 setup utility gets the job done,
it's a poor user experience.

What's needed is a highly graphical client/server application similar to the
type designed by Bernd Koch, DF3CB for the Alpha 87A amplifier.  That
package has client and server components, and the GUI is a high-resolution
graphic of the amplifier complete with switches, LEDs, panel graphics, even
the logo.  Clicking on the GUI is just like finger presses on the actual
amp.  It would be great to utilize the KPA1500's Ethernet port but even
client/server connectivity via USB is fine for now -- just to get something
going other than the KPA1500 setup utility.

I'm willing to help finance the development to get something moving along
now and not some TBD date in the future.  

Paul, W9AC

[Elecraft] [K3] factory upgrade to K3(s)

[j...@kk9a.com]

I have seen more than a few people selling a K3 but advertising it as a
K3S. When you look into their radio more you learn that it was a K3
upgraded to a claimed K3S.  While it is fantastic that an older K3 can be
upgraded, it will still never be a K3S and should not be called one.

I worked them on 40cw a few minutes ago.

ATNO!

Good luck!

[ab2tc]

Hi all Elecraft DXers,

What happened to the Baker Island DXpedition? They were supposed to be QRV
today, but their latest news update on the website was June 4.

Re: [Elecraft] [K3] factory upgrade to K3(s)

[Nr4c]

Back when the K3S was announced, I sold my existing radio for about $1200 less 
than the K3S price and ordered a new K3S and put up the $1200 it would have 
cost me to upgrade. I did keep my old K3 for FD and other portable activities.

[Elecraft] KX3 - Strange Behaviour

[Kurt Pawlikowski]

Good morning!

    Sorry for the length of this post: Its a bit complex and I needed 
to let people know that I *think* I know what I'm talking about! {'-) k


    Well, while Field Day 2018 is now in the past, I am having some 
concerns about my KX3. This is a little hard to explain, but here goes!


    Our setup was in, unfortunately, a fairly high noise area. I was 
working 20 CW. The noise level was S3, with times reaching S6. I 
believe, "normal" would be closer to S1. And, of course, lots of signals 
all over the board signal strength wise. Many of them very strong (10 to 
20 over 9!). Also note that this unit has the crystal filters and ATU. I 
also have the KPA100, which also has the built in ATU. I upgraded the 
KX3 software to the latest just last week in preparation for FD. Okay, 
that's the setup. Here are my observations:


    First, my KX3 has "some" opposite side band bleed through. On 20 
CW, I believe it is using the equivalent of lower side band (as you tune 
from higher to lower frequency, the CW notes go from "high" to "low"). 
As you pass through zero beat, on reasonably strong signals, a "ghost" 
signal can be heard going from "low" to "high", but it is very 
attenuated. This is what I consider "normal" (or perhaps "average") 
operation for a KX3 as configured. But, there's more...


    I started to notice that, as I was tuning "down" the band (from 
higher frequency to lower), there were several "artifacts" (for lack of 
a better word). First, the several things I noticed were "in sync" with 
the expected behavior of pitching from "higher" to "lower" as I tune the 
Rx frequency from "higher" to "lower". So, as far as I understand, 
/_not_/ opposite side-band "bleed-through." The first artifact seemed to 
mimic a signal, but it had a distinct difference, which I'm at a bit of 
a loss to describe. Let's just say "muffled," though that's not 
accurate. If I remember correctly, it was always a strong signal and 
seemed to shift with changing frequency properly. I could recognize it, 
so at least I knew it and could ignore it. Now for the coup d'etat...


    I also noticed that I was apparently receiving "ghost" signals that 
were about 500 (or so) Hz between. These signals seemed identical to 
each other. With the large number of signals on the bands, my bandwidth 
was narrow - between the tightest (I believe 50 Hz?) and a maybe 1 k. 
This is the artifact that bothers me. I have no idea which one was the 
"real" signal (like something from the old "What's My Line" TV show!). 
So, here's my question: Has anyone noticed something like this before? 
Is this some sort of configuration issue or is it hardware, or maybe 
it's just me (!). I don't know if I can reproduce it, so...


    Anyway, any input is appreciate it. Thanks!

    kurtt,

    WB9FMC

[Elecraft] KH1/KH7Z on K2

[Martin Sole]

A short video on my youtube channel listening to KH1/KH7Z on 14.210. I 
worked them on the K3, with amp, but Q5 on the K2. Now to see if it real 
or...?
