 What ever you do, don't press the SPLT button to go into split  mode when 
you have the condition you described because if you do, you will screw up 
the band sequence when you step through the bands.  At one point I had 3 
80m bands and no 60m and 40m when I cycled through the bands.  Until Wayne 
gets it fixed, be careful to not have different bands in VFO A and B.

Re: [Elecraft] K3: Strange VFO Behavior

[Toby Deinhardt]

Hi Ed,

I ran into this a few weeks back, reported it to Elecraft and was told 
that this is a known problem. Imho, it is not a trivial problem, so the 
firmware fix may take awhile.

RE: [Elecraft] TRANSLATION: K3 Subreceiver Status Update (KRX3 option)

[John Gaynard]

I doubt you'll get any chuckles from the majority of list readers.  Probably
just the opposite.  I do not believe that Wayne's emails need any
translation.

sure that more than a few folks have ordered the K3 based upon the 
existence that option.  THANKS for buying our sales

TRANSLATION: We hope you'll latch onto this part of the spin, and not

and didn't let you know until we couldn't explain it away anymore.

>(I know, I know -- "Stop rambling and get back to work!")

TRANSLATION: Let's hope the cute signoff will take the edge off of

Re: [Elecraft] K2 - getting ready to build

[Don Wilhelm]

John,

You can add the options in any order, and the desoldering is not 
extensive for any of them.


The inexpensive kit that you refer to is the "Rework Eliminators", and 
while beneficial to many, there is one shortcoming related to the K60XV 
that you should be aware of.  The Rework Eliminators would have you 
change the value of C71 and set the K2 menu D19 parameter to ON.  That 
precludes you from finally setting the VCO voltages (voltages at R30) 
until you actually install the K60XV.  In other words, the K2 cannot be 
fully tested for VCO voltages with the rework eliminators in place.  Is 
this a major problem? - yes, maybe, no.  If you are aware of this 
situation and follow the directions in the rework eliminator 
instructions carefully, it will not be a problem - but this part of the 
rework eliminators is not exactly 'plug and play' because you will have 
to re-visit the R30 voltages again after you add the K60XV.


Other than that, enjoy the build.  As I have stated, I do not believe 
that adding the options later is any great deal (with or without the 
rework eliminators) - the number of components to de-solder is quite 
small for any particular option - just follow the instructions provided 
by Elecraft.


Enjoy your Minnesota winter - I am quite happy here in North Carolina. :-)

Don W3FPR

Hello,

I am getting ready to start my K2 project (after this weekend's VHF 
contest is done.) I have the base K2 kit + KAT2, + KSB2 for my initial 
build. I am planning to add a couple more pieces in the future (KIO2, 
K160RX, K60XV.)  I know that some people have used some sort of 
inexpensive kit to allow to for the future upgrade path.


Are there any opinions one way or the other on that? My main concern 
being any parts that I might need to desolder in the future if I don't 
plan for the options now.


After building my XV222 (for this weekend's contest) I am looking 
forward to starting the K2 project. The dead of winter has arrived in 
Minnesota so it is a good time of year to melt some solder.

Re: [Elecraft] K2/100 + KAT100 + Cushcradt R8 Vertical

Re: [Elecraft] K2/100 + KAT100 + Cushcradt R8 Vertical

[Doug Person]

Phil,

The R8 has been discontinued for some time so I assume you have a line 
on a used one. There has been some issues with getting parts for the 
older Cushcraft verticals.  I've had most of the so-called no-radial 
verticals and the Cushcraft is more or less the middle of the pack. I 
found the GAP Titan to be superior.  Not too great on 80 but decent 
performance on the other bands.  My current choice of these types is the 
Hy-Gain AV-640 and AV-620.  The AV-620 is available from R&L Electronics 
for $269 - which is, in my book, a bargain ( I have no association with 
them - just passing on my observation).  The AV-620 covers 20 through 6 
meters and is very well built.  You can download the manual from Hy-Gain 
to get a good sense of the antenna.

[Elecraft] TRANSLATION: K3 Subreceiver Status Update (KRX3 option)

[David and Dianne on Comcast]

Hi Everyone,

The delay of the second receiver option is to me both highly regrettable 
and somewhat deceptive. 

I, for one, based my purchase decision greatly on this option being 
ready for prime time which is obviously was not and apparently will not 
be any time soon.  Production delays are forgivable and understandable 
but discovering that this option which is touted as a big-time feature 
but is really no where near ready is confidence deflating.


I have been personally patient waiting for my K3 (as are many others) 
and occasionally publicly supportive on this list of the delays that 
Elecraft has been experiencing. Now we discover that a MAJOR K3 feature 
is no where near production ready, if even designed at this time. Come 
on


As for me, I'm reassessing my purchase decision  and may wait until the 
K3 project has matured.


I have bought lots of transceivers over the years and this was to be the 
first I ever considered buying in its first year. I now wondering if I 
should still make that exception.


The Ten Tec Omni VII has a 5.0 Review rating out of 25 reviews on Eham 
and may be a worthy and fully developed competitor.


Very disappointed in all of this.

Elecraft does a lot of great things but this one was really lame.

Flame away. I could care less.

My $.02

Gents,

Let me put the speculation to rest, since I look at this on a daily basis,
it might make it shorter to read 

The ARRL, in our usual disguises to avoid getting a "finely tuned sample"
has actually ordered and received two K3s. One was a "bare bones" 10 W kit
version -- the other a factory built 100 W full up model. Both have been
received and the kit has been built and the other, less the not yet released
options, is in the ARRL lab.

Our original plan was to discuss both in a single review -- to be published
before CT sailing season (BTW, I start sailing season early )!

We have changed plans, since we don't have all of the options. We plan to do
the review of the kit version a bit earlier, and the full up version after
we have all the pieces.

So the primary data should be available early, while the detailed assessment
of the "full-up" unit will wait until we can make it "full up."

I am happy to say that I will be the lead reviewer and yes, I will push my
Viking II aside and bring it to the AWA Sunday AM/PM net some week soon!

So that's the plan -- and like all plans, subject to change -- but the key
data should be out there pretty soon!

I noticed this behavior this evening and I was wondering if anyone else 
could duplicate it.


I have VFO A on 6M USB and VFO B on 10M USB.   When I turn the VFO B knob, 
the VFO frequency changes, but the mode changes to LSB.  If I turn VFO A 
now, the VFO A frequency changes and the mode goes back to USB.  If I do a 
band down, I don't get 10M on VFO A, instead I still see 6M, plus get a 
PLL error message flash by.


Does anyone else see this?

Why not tune VFO A to desired frequency on 10m and then BAND^ to desired
frequency on 6m.  Then you can toggle between BAND^ and BAND Down with one
touch.  Same number of keystrokes as A/B but you are switching the BPFs
correctly.

Re: [Elecraft] K2/100 + KAT100 + Cushcradt R8 Vertical

[T. David Yarnes]

Hi Phil and All,

I have used an R7 for many years, and it has performed very 
well.  I was always able to load it effectively on 40 meters 
across the band, even though I had it set for the CW 
portion.  Other bands are not a problem at all.  The K2 ATU 
does a very nice job.  I did have some problem on the higher 
end of 40 meters using the ATU in the FT-1000 MP Mark V.


Just recently I also added an R8 here, and I am currently 
using it with the K3.  If anything, the R8 seemed a little 
easier to load on 40, even with other rigs.  The K3's ATU 
has no problem loading the R8.  I assume the ATU in the K3 
is reasonably similar to the K2's ATU.  I haven't actually 
tried using the K2 on the R8 yet, but I doubt there would be 
a problem.  40 meters would be your only possible problem 
band, and if you want to be a little extra cautious you 
might consider setting it for the middle of the band--around 
7150 khz or so.  I think that would probably be something I 
should do as well, just to make life easier.

Re: [Elecraft] Alinco switched-mode power supply from RSGB

Hi all,

The enjoyment of my new K3 was being severely compromised by an old  
linear power supply whose fan sounded like an old vacuum cleaner  
and whose transformer buzzed loudly in time with my cw at any  
powers above about 20 watts.


So I decided to take a chance on a switcher and bought the Alinco  
DM-330MW on offer at the moment in RadCom for 79.95ukp (RSGB  
members) until the end of February. What a difference.the  
silence is deafening! I can now hear the K3's dulcet sidetone and a  
quick flick across the bands has not shown up any obvious switching  
noise either.


It's small size and weight makes it an ideal companion to the K3  
and the duo would make a great combo for a field day or dxpedition.  
I'll reserve final judgement until I've used it a couple of weeks  
and had a good check for digital nasties but it looks very good so  
far.




I have had my Alinco DM-330 for several years (it replaced an Astron  
linear supply) and have been quite happy using it with my K2.  The  
adjustable output makes it easy to supply sufficient voltage for  
charging the internal battery and I have never noticed any switching  
noise.  There was a review in QST which showed a much cleaner  
spectrum than most of the other supplies they tested.

Re: [Elecraft] K2 - getting ready to build

[KBG Luxford]

John,

If you do not purchase and install the Rework Eliminators IMA microphone 
adapter product, AND you are going to use a mic different from the 
Elecraft MH2 or Proset, then DO NOT solder anything to the long gold 
pins of the DIL microphone header.  If you do, you will have trouble 
with the installation of the IMA should you wish to add it at a later 
date.  If you want to look at using different mics, then I would suggest 
you install the IMA now, as part of the build.


All the best with your project.  I have built two K2s, sold one and just 
finished the KPA100, and have not had so much fun and learning in years. 
 Now suffering withdrawal symptoms - shall just try to take comfort in 
a less depleted bank account and less ire from the XYL when all these 
packages stop arriving from Aptos.

Re: [Elecraft] K2/100 + KAT100 + Cushcradt R8 Vertical

[DW Holtman]

Phil,

I love on a small lot and this forces me to use something other than a full 
size Yagi on a 100 foot tower. I owned an R-7 for about 12 years and it 
performed great. Over the years (after 9 or 10 years) the way its 
performance, degraded. It got to the point where I had to take it down, 
clean all of the connections three or four times a year and it would work 
again. Well I traded it and bought an R-8. It is now about a year old and 
works fine. It does not have the traps that the R-7 had and I suspect it 
will last a long time. I live in Salt Lake city where we do get strong 
winds, but have never caused a problem.


It is sort of a compromise antenna. But for what it was designed to do it 
works great. I also have about a 70 foot longwire antenna I use for 
shortwave receiving on my R-390As. It usually brings signals in a little 
stronger than the R-8. I'm going to convert it into an inverted "L" so I can 
start getting out on 80 meters.


Hope this helps.

Best,
DW Holtman

Re: [Elecraft] K3: Strange VFO Behavior

[Ed K1EP]

Reminds me of the old comedy routine -

Patient: Doctor, it hurts when I do this.
Doctor:  Don't do it.

If I am casually tuning around, hunting DX and I want to check on two 
different bands (like the current multi band/op dxpeditions), the 
easiest thing for me to do is put one freq/band in one VFO and the 
other freq/band in the other VFO.   Hitting A/B allows me to 
conveniently switch between the two.  Seems fine as long as I don't 
accidentally hit VFO B in the process.  I don't have exceptionally 
fat fingers, but I do manage to hit the wrong knobs once in a 
while.  I don't think that it is good behavior for this to 
happen.  What if you don't purchase the second receiver?  Are you not 
allowed to do this?

Ha, ha!!! Let's hope they are growls of pleasure, not pain! 

Take a D-E-E-E-P breath and do the build ONE step at a time, and double
check your parts placement before soldering! 

I built my K2 in 2000. It's worked like a champ in spite of being one of the
test machines for many of the "improvements" to the K2 gene pool over the
years.

Following this reflector since 2000, I've noticed one complaint begin to
turn up among a few owners: intermittent problems!

In every case that I've followed, the intermittent turned out to be a lead
that was never soldered. Elecraft uses high quality boards with
plated-through holes. A bare, unsoldered lead can hang in one of those holes
for years before enough oxidation builds up or it becomes loose enough to
start losing conductivity. 

So I suggest keeping the three following things in mind as you build:

1) All parts have a tendency to jump from one place to another without
warning. After you put R3 in the spot for R3, when you reach for the
soldering iron you may discover that while you looked away it: a) jumped to
another location or b) changed to a different value. Parts tend to do this
more easily as the hours wear on.. 

2) An unsoldered part remains unsoldered until you solder it, even if it's
years later.

3) Intermittents are the worst sort of trouble to locate.

Hi John,

In addition to elminating the need to do any desoldering or any
additional soldering, our assembly method also saves you from having
to do any significant disassembly of the enclosure that otherwise
required when adding some of the options.

Beyond our assembly method and its associated header and duplicate
K2 parts kits, we now also have a neat internal mic adaptor for the K2
that can be easily configured to support more than 50 microphones.
(The alternative is rather significant disassembly of the K2 should
you wish to change the front panel mic connector pin out, and no easy
way to install a bias resistor.)

You can find several reviews of our products on the eHam website
at http://www.eham.net/reviews/detail/6372 (for our headers) and at
http://www.eham.net/reviews/detail/6918 (for our mic adaptor).

See our website at http://www/unpcbs.com/ for details and
especially check out our "Frequently Asked Questions" page.  Feel
free to email Ken Kaplan and myself at < support at unpcbs dot com >
if you have any questions.

John,
I'd consider getting the Rework Eliminators http://www.unpcbs.com/ . 
When you're done with your K2, you'll be able to plug in future modules 
without a lot of hacking. Great for troubleshooting too. If you have 
different microphones you might want to use, consider also their 
Internal Mic Adapter.


(Disclaimer: I use these parts when I build K2's for my clients. I'm 
listed on their web site, but I don't get any financial benefits.)

[Elecraft] K2 - getting ready to build

[John Hoaglun]

Hello,

I am getting ready to start my K2 project (after this weekend's VHF 
contest is done.) I have the base K2 kit + KAT2, + KSB2 for my initial 
build. I am planning to add a couple more pieces in the future (KIO2, 
K160RX, K60XV.)  I know that some people have used some sort of 
inexpensive kit to allow to for the future upgrade path.


Are there any opinions one way or the other on that? My main concern 
being any parts that I might need to desolder in the future if I don't 
plan for the options now.


After building my XV222 (for this weekend's contest) I am looking 
forward to starting the K2 project. The dead of winter has arrived in 
Minnesota so it is a good time of year to melt some solder.

Interesting.  I was wondering about this one, although I was slightly 
put off by the "review"; it looked more like it was written by the 
distributor's marketing department... "we though this was so good we 
just had to offer it to you".


One question I have are whether I really need one.  I have a barefoot K2 
and can power it off an SLA battery, which I float on a linear supply I 
built in my youth (OC16 pass transistors!). Using indoor antennas in a 
flat means going to 100 watts, except in the early hours of the morning, 
might not be a good idea.


Another question is whether there is any realistic alternative that 
would satisfy my desire to build as much as possible myself, but without 
having the electronics knowledge to produce a complete design with 
safety and EMC considerations covered.



across the bands has not shown up any obvious switching noise either.


Looking at reviews of other variants (the MW doesn't even appear on 
Alinco's web site) some people seem to have severe noise problems and 
some no problem at all.  It looks as though there may be some Friday 
builds out there.


Any views on quality, alternatives, and whether prices are likely to 
drop to the extent that just in time purchase is best, would be welcome.

Re[Elecraft] quest for K3 recording - 2.8Khz filter

[Barry N1EU]

If some K3 owner out there with the 2.8Khz 8-pole filter installed could
possibly indulge me, I'd appreciate it if you could make a simple 10-sec WAV
file recording with your K3 audio connected to your PC's soundcard and email
it to me:

please adjust the K3 to usb and the widest dsp selectivity that will still
allow the 2.8Khz filter to be engaged

please tune to an empty spot on any band - I just want to hear the band
noise and run a spectral plot

Thanks & 73,

Re: [Elecraft] Changing K2 Microphones for the K3

[Don Wilhelm]

John,

Since you have the resistor in the connector, it will work fine with the 
K3 - BUT - the mic bias will be coming from the resistor in the mic 
itself - for that reason, do not turn the K3 microphone bias on.
Others using those same microphones with the K3 would want to turn bias 
on because they have no resistor in the connector body.

I have ordered my K3 and expect it in 2008, so I want to be ready.

Will I need to remove the resistors from the mic connector shells of 
the MH2 and MD2 in order to use them with the K3?

[Elecraft] K3 operation on real data modes (TOR)

[Dave G4AON]

Hi guys

I've just acquired a KAM plus, operation on FSK-D with the K3 worked 
first time and is great except for the usual lack of anything except the 
odd European Pactor mailbox. Setting the KAM for 2125/2295 on direct FSK 
keying was easy, the dial frequency equals the mark frequency for the 
mailbox. As per the old days of some 20 to 25 years ago on Amtor, 
perfect copy with as little as 1 Watt.


Anyone else got Amtor, Pactor 1 or G-Tor care for a sked sometime? 80m 
during the evenings in Europe, or perhaps further on a weekend during 
the day. How about a Tor revival???

RE: [Elecraft] K3 Power Supply

[Ron D'Eau Claire]

Although Elecraft recommends a 30 amp supply, I have used my Astron 20A
linear supply with no problems. 

The K3 stays within the Astron's 16 amp continuous, 20 amp intermittent
rating on all bands. One would have to put a brick on the key at full power
and go away to exceed the Astron 20A's specs (or run full power in a 100%
duty-cycle data mode without breaks).

[Elecraft] [K3] Direct transmit PSK31

[G4ILO]

Has anyone used successfully the direct transmt PSK31 mode, PSK D? It seems
broken to me.

FSK D appears OK. I key the rig and nice sounding RTTY comes out. It decodes
OK. I can also play text stored in the message memories. I just need to be
able to send a complete message into the memory without making a mistake. :)

When I key the rig in PSK D, a tone that sounds like PSK31 is transmitted
but it is accompanied by a regular loud tick-tick-tick several times a
second. This is heard on the monitor, and also transmitted over the air. The
characters I am sending, and which appear on the VFO 2 display and therefore
are presumably modulated on to the signal, are not decoded by the decoding
software. I have tried direct pickup via the PC mic from the K3 monitor, and
over the air, the results are the same. I have tried with the receiver set
to USB and LSB, though I'm not sure it matters with PSK31, the result is the
same.

Also when I try to send a message memory I get the report "No DVR
installed."

Although PITCH in PSK-D is set to 1000 the actual audio signal appears at
about 1084Hz.

By the way, is it possible to change the center frequency used for DATA A?
It seems centered at about 1600Hz which is tiring on the ears. But when I
press PITCH it replies N/A.

Re: [Elecraft] K2 -- RX audio

[Darrell Bellerive]

I replaced C25 and C26 with .22 uF ceramic capacitors the other evening as 
Matti has suggested. It does make a nice difference in the low end.

I have the KAF2 filter and am using the standard SSB filter as constructed in 
Rev E of the KSB2 module. The specs state it is a 2.3 kHz filter.

I notice that the coupling capacitors in the KAF2, C12 and C13 are .22 uF 
devices.

I can't help but wonder what changing all four caps C25 and C26 on the control 
board and C12 and C13 on the KAF2 to .33 uF would do. I don't have enough .33 
uF ceramic caps in the junk box or I would try it. Perhaps I will remember to 
order some from Mouser next time I place an order.

I have some polypropylene caps of the right value, but they are a bit to large 
physically to fit. The audio buffs seem to favor these over the ceramic types 
as they say they have a better sound to them. Be interesting to see if it 
would be noticeable.

Re: [Elecraft] K3 Power Supply

[Geoffrey Mackenzie-Kennedy]

Thom,

The power supply used here for several years with rigs of similar power
output as the K3/100 is a Diamond GSV-3000, which is a 'linear' type (large
transformer!) not switching.

Input:   230v AC  50 Hz   (There is a version for your line voltage @ 60
   Hz)

Output  :  1 to 15V DC, adjustable using a front panel control.  30 amps
   continuous at 15V,  35 amps maximum (CW/SSB)
   Two auxiliary outputs rated at 6 amps.

Meters  :  Two -  DC Voltage supplied and  DC Current drawn.

Cooling :  Fan, VERY quiet if you can hear it.

Physical :  Colour - black.  Weight - 9 kilograms.
   Dimensions - 15 x 25 x 25 cms (H x W x D).

My K2/100 sits right alongside the right hand side of this supply separated
by roughly 2 inches, and the K2's VCO without the VCO mod kit is not
affected by this power supply.

The usual disclaimers apply.

Thank you.  Then AFX wil have no effect on the internal speaker, which

To summarize, assiging SPKR+PH to the RIT PF keu and setting spkrs=2 is 
a complete solution for people who use AFX and want to toggle between 
headphones and internal speaker, and do so with one button push.

The internal speaker is wired to the Left channel.  Operationally, it 
just means that you won't hear the stereo effects (AFX) (if enabled) 
unless you plug in stereo headphones.  If you do plug in stereo 
headphones, you'll hear the chosen AFX.


Later, if/when you install the subreceiver, you may or may not hear the 
subreceiver audio, depending on how you set up the subreciever.

RE: [Elecraft] K3 Power Supply

[Dick Dievendorff]

A lot depends on how you plan to operate.

I have a Gamma Research HPS-1a http://www.gammaresearch.net/ that is ideal
to take with me for portable operation for CW and SSB.  It handles a 100
watt transceiver on these modes fine, but would not handle RTTY at full
power or very slow CW.  It's tiny and light. It's a switcher, with a 5 FARAD
output capacitor.  It's quite popular and there's a bit of a waiting list
now.

Perhaps a smart battery charger for your batteries would be a good choice
for you. Try http://a-aengineering.com/QST_58.pdf  
This has the advantage of emergency capability if the power is off.  I
choose not to have big batteries in my house, but I'm guessing a sealed
battery would be safe enough. My K2 has an internal battery, and I'm using a
smaller version of this smart charger to keep its battery charged.

You can choose a small switching supply like one of the Samlex or Alinco or
Astron offerings.  The Alinco DM-330MV has many fans.

I plan two K3s for SO2R contesting.  I use an Astron 70 amp linear supply
and an 80A West Mountain Engineering power pole distribution panel and all
the 12V devices in my shack (antenna switching, SO2R controller, power
meters) connect to it via Anderson Power Pole connectors.  I don't need this
much current capacity, but everything runs well under its designed
capability.

Some switching supplies are noisier than others, so if you're considering a
switcher, look over the reviews carefully.  The K3 is quiet enough that
you'll hear everything. Many high-end rigs have built-in switching power
supplies.  If the switcher is built for communications use it has a chance
of being reasonably quiet.  But you won't keep a noisy switcher very long.
Pay the money for a good one.

Subject: [Elecraft] K3 Power Supply

Looking for suggestions for a power supply for the K3/100

The only thing I have handy(well, if I can get them upstairs) are 
some sealed lead acid batteries from motorized carts.

I have a few that are 34ah and at least one that is 55ah and one of 
the chargers that autosenses battery charge level.

Seems to me this should do the job, but I've never run a 100 watt rig 
on batteries, so I really don;t know.

thanks in advance for suggestions.

Reasoning: There was way too much buzz after the K3 intro from the contesting

just another radio, and I'm sure the guys at ARRL figured that out at a very

Re: [Elecraft] K3 Power Supply

[Leigh L Klotz, Jr.]

Thom,
I use a Gamma HPS1a sometimes but it can't handle 120W CW sustained, 
more like 80W but can do 100W SSB.  I also use a Group 24 battery with a 
Battery Tender (1.5A) or a 5A solar panel and controller.  The solar 
panel isn't doing as well in the winter.  For the battery route, the A&A 
charger many people like, and it is 5A.   I use Tempest batteries 
because there is a nearby seller and I can avoid shipping.  They are 
sealed and so I don't worry about hydrogen venting.   Many folks like 
rhe golf cart wet cells and keep them outside.

Re: [Elecraft] [K3] front phones socket duability

[Lyle Johnson]

If I have nothing plugged into the external speaker, and just want to 
toggle between headphones and internal speaker, what does the internal 
speaker do when spkrs=2?  That is my situation.


The internal speaker is wired to the Left channel.  Operationally, it 
just means that you won't hear the stereo effects (AFX) (if enabled) 
unless you plug in stereo headphones.  If you do plug in stereo 
headphones, you'll hear the chosen AFX.


Later, if/when you install the subreceiver, you may or may not hear the 
subreceiver audio, depending on how you set up the subreciever.

Re: [Elecraft] K3 Power Supply

[Dave Martin]

I've run my entire station on batteries, either a marine battery or
gel cells in parallel, for years.  I found a noise free switching
power supply good for around four amps (and current limited) and added
a voltage adjustment to it so I could set the maximum voltage to the
battery.  Its four amps was enough to power my accessories and the HF
when on receive, and the charger would catch up between transmissions,
no more active than I was.  It's nice to simply walk in and turn on a
radio without having to turn on a power supply.

Re: [Elecraft] TRANSLATION: K3 Subreceiver Status Update (KRX3 option)

[Tom Hammond]

Mike:

Other than possibly Lyle, KK7P, and of course Wayne, I know NO other
FTs who have seven SEEN the KRX3 yet... we're waiting just as everyone
else is.

For my K3 contesting, I'm using the 400 Hz CW filter, but I'll probably
buy the 1.8Khz (SSB), and 1kHz (CW) filters in time. Actually, I'm kinda
waiting to see what comes of the proposed 'programmable' filters which
might well replace any 'extra' filters I'd want to buy.

Second question for the contest types on the list, what filters have 
you chosen for your K-3.  You can respond direct if you like unless

Re: [Elecraft] Aptos - silicon village?

[Eric Swartz WA6HHQ - Elecraft]

I know Trey (N5KO)  and Mark (AG9A) at INRAD very well. Trey lives in 
Aptos, and when he and Mark bought the company from George last year 
they relocated it here. Very convenient for us!


They are located about a 10 minute walk, or a 4 minute drive, from our 
offices on the east side of HW1.  Our customer filters are hand carried 
from their door to ours. We're all about 1 mile from the beach on 
Monterey Bay. One of these days I'm threatening to have an engineering 
design review down at the beach. ;-)


So I guess Aptos is now the West Coast center for Ham Radio 
manufacturers, dude...

As a former resident of Aptos, CA (1984-2002), I've wondered this

I've seen no indication on the Internet that there is any other 
connection. However, Aptos is not a big place. :-)  Seems distinctly 
odd that Inrad should just HAPPEN relocate there. I'm curious, too. 
I'd almost be willing to bet that there is some connection. How about 
it, Eric?

Re: [Elecraft] [K3] front phones socket duability

[Lyle Johnson]

In fact, I think it stays in all the time with this setting.

Set CONFIG:SPKRS = 2 and then it won't drop out


Here is what is happening.

If the DSP believes there is a monophonic listening channel in use 
(SPKRS = 1, as in using the internal speaker and headphones not plugged 
in) then all audio is folded in the left channel (which drives the 
speaker), and the right channel is a duplicate of the left (in case you 
have stereo headphone spluged in and SPKR+PH is set to YES).  That way, 
if you had the sub-reciever, for example, piped to the right and the 
main receiver piped to the left, you can hear both receivers in the speaker.


Most external speakers these days are mono, and there is no "ring" 
terminal on the plug: it just has a tip and a shell.  When you plug such 
a connector into the K3 external speaker jack, you are *shorting* the 
right channel.  Not damaging, but not a Good Idea either.


So, the KIO3 board has a relay in series with the right channel output 
to the speaker jack. If you have SPKRS = 1, then the relay remains open 
(to disconnect the right channel speaker amplifier from the external 
speaker jack) and it is safe to plug in a mono plug to the external 
speaker jack.  And the radio will operate with identical audio in the 
left and right channels, so your stereo phones will work properly.


If you set SPKRS = 2, then the relay closes, right channel audio is 
passed to the stereo speaker jack (since you specifically told the radio 
you were not plugging in a mono plug into the jack by manually setting 
SPKRS = 2), and stereo audio is created as appropriate.


More than you ever wanted to know, but there it is.

[Elecraft] Another K3 in on the AIR !

[joshLO]

K3 unit 156 is ALIVE!
After over 50 years of Radio ,  I am very impressed with
the K3/100  - especially the RECEIVER - 
It has NO DSP sound ( audio artifacts ) -the 
roofing filters are a joy to use in busy contest conditions,
with the Upgrade-able firmware  and an ENGLISH
speaking manufacturer that is highly responsive to 
user feedback, it is leading the PACK !

I will leave it to the more technical ops to give you
its specific points of merit   Hip Hip Horay !!!

[Elecraft] K3 Power Supply

[Thom LaCosta]

Looking for suggestions for a power supply for the K3/100

The only thing I have handy(well, if I can get them upstairs) are 
some sealed lead acid batteries from motorized carts.


I have a few that are 34ah and at least one that is 55ah and one of 
the chargers that autosenses battery charge level.


Seems to me this should do the job, but I've never run a 100 watt rig 
on batteries, so I really don;t know.

Re: [Elecraft] [K3] QST Labs review? -- Pool?

[Terry Myers]

I think the K2 that was reviewed in QST was around serial number 495.  The 
K2 hype was no-way near as noticeable as he the K3 hype.  My thought is that 
the ARRL has one now or getting one this month. The packaging of the test K2 
and my K2 got mixed up and there was some sorting out to do.  The 
manufacturer did know which K2 was going to be the test radio for the QST 
review.  I waited until I had gotten my hands on a K2 before I ordered, 
which must have been a little more than a year after orders were taken at 
Dayton.  Things were not happening nearly as rapidly with the K2 as they are 
with the K3.


QST and the ARRL web publishing seems to repeat a good bit of information 
seen on the QRP-L and Elecraft reflectors.  My guess is they have it in the 
queue.  Because the K3 hype was on the reflector very early on.


Now does that change any of the action in the pool?

I'm betting they already have one or will have it shortly. I'm going to go 
way out on a limb here. Put me down for July 2008 issue.  :-)


Reasoning: There was way too much buzz after the K3 intro from the 
contesting and DXpeditioning crowd for ARRL to wait months on end to get 
one. This is not just another radio, and I'm sure the guys at ARRL figured 
that out at a very early date.

[Elecraft] K3 'S' meter and notching

Thanks! I had no idea.

Yes, that's what I'm doing, but using PF1/2 to toggle that, so the speaker
is not on when I'm listening through phones - since I'm listening through
phones to avoid annoying the rest of the family !
It's working well.

[Elecraft] Changing K2 Microphones for the K3

[John Huffman]

For my K2 I use the MH2, MD2, and a Heil Proset.  For flexibility, 
instead of putting the 5.6k resistor in the K2, I put one each in the 
microphone connector shells of the MH2 and MD2.


I have ordered my K3 and expect it in 2008, so I want to be ready.

Will I need to remove the resistors from the mic connector shells of the 
MH2 and MD2 in order to use them with the K3?

[Elecraft] TRANSLATION: K3 Subreceiver Status Update (KRX3 option)

[Don Rasmussen]

>> For fun, I thought I'd provide an "East Coast"
translation of this recent announcement from Elecraft.
--

As Rodney Dangerfield would say "tough crowd - tough
crowd"!

There is probably a fair amount of truth in Steve's
humorous comments, but I balance them against what the
Elecraft guys have on the table today. They offer
several product lines that operate at the top of the
specifications charts, without a revolving door to a
huge service desk, there's immediate attention to each
user on any specific product issue, and at a price
that undercuts the competition.

I'm resigned that the highest cost of accepting
Elecraft production model is time, and have planned
accordingly. 

It's still painful, all this waiting. But with respect
to the subreceiver it beats a weird alice design
w/marginal isolation pushed out early. You might
expect that in some of the competing manufacturing
models. 

YMMV (your milage may vary).

[Elecraft] Alinco switched-mode power supply from RSGB

[Stewart Rolfe]

Hi all,

The enjoyment of my new K3 was being severely compromised by an old 
linear power supply whose fan sounded like an old vacuum cleaner and 
whose transformer buzzed loudly in time with my cw at any powers above 
about 20 watts.


So I decided to take a chance on a switcher and bought the Alinco 
DM-330MW on offer at the moment in RadCom for 79.95ukp (RSGB members) 
until the end of February. What a difference.the silence is 
deafening! I can now hear the K3's dulcet sidetone and a quick flick 
across the bands has not shown up any obvious switching noise either.


It's small size and weight makes it an ideal companion to the K3 and the 
duo would make a great combo for a field day or dxpedition. I'll reserve 
final judgement until I've used it a couple of weeks and had a good 
check for digital nasties but it looks very good so far.


73,

Stewart Rolfe, GW0ETF  (K3  #145)

PS - Anyone want to buy a Watson W-30AM power supply with built in 
sidetone?

Re: [Elecraft] Err TXF

[Julian G4ILO]

OK. If that's the case, we were barking up the wrong tree here.

I've just done Spectrogram plots of band noise through the 2.7KHz
filter with the DSP opened up to max. They are at
www.g4ilo.com/images/usb.gif and www.g4ilo.com/images/lsb.gif if
anyone is interested to look at them. They look pretty similar except
the skirt widens out at about 20db down on the HF side, and there is
more high frequencies getting through on LSB than USB, which I can
hear. The bandwidth at -6dB down certainly looks wider than 2.4KHz.

I can't see a difference that explains why LSB and USB don't sound the
same to me when monitored on-air. I've monitored the transmission
using both the K2 (which isn't really a good tool for this since its
opposite sideband responses aren't identical either) and the FT-817
which has a fairly wide standard SSB filter and sounds the same on
either sideband.

Subject: [Elecraft] K3 Subreceiver Status Update (KRX3 option)
To: Elecraft Reflector 
Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset=US-ASCII; format=flowed

I wanted to give those who've ordered a K3 subreceiver a status update.
First, thanks for your patience; I realize the subreceiver has been
significantly delayed. (This is also pushing out the DVR. Lyle, KK7P
and I are collaborating on the PCBs and firmware for both units.)


TRANSLATION: We've been stringing everyone along for, what...9 months 
or so?  We promised that very useful KRX3 option, and we're pretty 
sure that more than a few folks have ordered the K3 based upon the 
existence that option.  THANKS for buying our sales 
puffery!  Unfortunately, we can't manage to bury the truth any 
longer.  Here's the deal: We're nowhere close to being ready on the KRX3.





When we release a product, it has to meet a number of criteria. Raw
performance by traditional measures is just one of these. Fortunately
the subreceiver has met our expectations in this regard, with dynamic
range virtually identical to that of the main.




TRANSLATION:  blah blah blah blah...this is filler to divert your 
attention...let's hope they take the bait.




But there are two other requirements that we must meet: excellent
mutual isolation between the main and receivers, and ease of
installation. Recently, we made the difficult decision that both must
be improved.

Isolation between the receivers is critical to usability. For example,
if you're listening to an extremely strong signal on one receiver, none
of it should leak into the other's I.F. After extensive testing, we
concluded that we were close, but needed more isolation.

Regarding installation: Someone with no experience should be able to
install or remove the subreceiver without much difficulty. The present
installation process is just a bit too complex once all other modules
and their associated cables are in place; the left side, chassis
stiffener, and several cables have to be removed. This has a secondary
effect, which is to make it very time-consuming to change crystal
filters on either receiver. We felt that we should improve this now,
before all fabrications were cast in stone.



TRANSLATION: Our first cut at a design, and the prototypes we've put 
together from that, don't work very well.  We've tried and tried, but 
they just don't.




Both isolation and installation can be improved with changes to our
original KRX3 PCB layout. I'm working on this now. Once the PC board
and shield designs are complete, we'll quickly build first articles and
run them through all of the tests again.


TRANSLATION: We're doing a major re-design.  Next come the prototypes 
and testing.  No idea when it'll be ready.



I'm confident that these improvements will allow the subreceiver to
live up to your expectations as well as ours. We'll post further
updates as we make progress.


TRANSLATION: We hope you'll latch onto this part of the spin, and not

Re: [Elecraft] [K3] QST Labs review? -- Pool?

[WILLIS COOKE]

I have heard second hand that the evaluation has been
done already and there has been some talks about it at
ham fests.  This information may not be accurate as I
didn't hear the talk myself and the source could be
confusing an evaluation of the K2.  If so, the source
was raving about how wonderful the K3 will be and has
congratulated me on ordering one.  I am far more
interested in the K5EWJ evaluation than the ARRL
evaluation even is the K5EWJ evaluation is less
scientific.  I just hope that the Order Date/Delivery
Date is not a linear function!  If it is, I have at
least 6 months to wait.

Meanwhile, read this if you have not already:

http://www.astromag.co.uk/k3/

This write up by G4AON is super good.  It may not have
as much test information as the ARRL reviews, but I
think it is super good and after reading it, I placed
my order on Dec 27.

Re: [Elecraft] Err TXF

[Greg - AB7R]

I think this is moot when it comes to TX.  As mentioned by Bill, you can ONLY 
use 
the 2.7 or 2.8 for the TX filter in all modes except for AM, that requires the 
6 
kHz filter for TX (for now).  Setting the BW in CONFIG for either the 2.8 or 
2.7 
filter is not altering the filter, rather it determines when that roofing 
filter 
turns on in relation to adjusting the DSP Filter width with the front panel DSP 
controls.  If you set the 2.8 at 2.8 and adjust the DSP controls from say 3.0 
kHz 
down to 2.4 kHz, the 2.8 will kick in when the DSP filter is set for 2.8.
If you set the 2.8 filter BW in CONFIG as 2.6 kHz, then the 2.8 filter will not 
come on until the DSP BW is set to 2.6 kHz.

So if you have the 2.8 set at say FL2, then you set the TX filter as FL2 for 
all 
modes except AM.  Setting the BW in CONFIG to a lesser value should not affect 
TX.

I have barely discovered how to get it on the air yet! Thank you for this
explanation. The bit about disabling the wider filters also solves the
problem of how to use something like Spectrogram to see the frequency
response of just the crystal filter. I didn't think of doing that. :)

Rob will be testing a K3 on loan from one of the Colorado locals.  He does
not publish full test reports on his website but they often show up on
specific rig forums.  I believe his latest on the SDR-5000 was published by
an SWL publication (Passport Radio?) but available to subscribers only.  Rob
was on the IC-7800 list since he bought a unit (subsequently sold) and I
would not be surprised to see him show up here.  In these forums he often
shares qualitative observations that are not in his published data (e.g. the
RX AGC impulse noise problems the IC-7800 and 7000 have).

So to answer your question, he does publish info but you have to look for
it.  I suspect you may see something published here eventually.

As a former resident of Aptos, CA (1984-2002), I've wondered this myself. 
Aside from the obvious fact that Elecraft uses Inrad filters, I've seen no

Re: [Elecraft] [K3] QST Labs review? -- Pool?

[David Yarnes]

Perhaps I'm wrong, but I thought there was also a good bit of controversy 
some time back as to whether or not Sherwood's measurements were correct. 
It might have been via the Orion reflector or the IC7800 reflector, but not 
sure.  Anyway, as I understand it, Sherwood had to go back and do a 
re-analysis on several radios.  Also, I seem to recall he had not really 
correctly evaluated the K2 when it first came out.  But maybe I dreamed all 
of this.

Rob Sherwood will publish a detailed technical evaluation long before ARRL
(sans fluff).  Rob also is not afraid of offending advertisers by
identifying genuine problems.  ARRL's Expanded Test Reports are very
worthwhile but I would rather read good fiction than most QST product
reviews.  :-)

In case some have not discovered how to use the internal meter, below are
some simple instructions.  This can be very useful for setting individual
FLx Gain, if you want more resolution than simply using the K3 S-meter.  All
you need is a steady signal source like the XG1 which will give you a
reasonable meter strength (S5 or higher).

Turn AGC Off.
Select Display = AFV and let it settle to a steady reading (value doesn't
matter).
Then select Display = dBV.
Reading should be 0.0 dBV (+/- noise or stability of your source)
Now you can compare in dBV at different frequencies (for bandwidth
measurements) or different filter choices (for differential gain
measurements).
Don't forget to turn AGC back on afterwards!

If doing BW measurements on the crystal filters, you must first set the DSP
BW using WIDTH to a value greater than the XFIL BW.  If you don't, you may
actually measure the combination of the XFIL and DSP bandwidths.  Likewise
if you want to check the DSP BWs, you must be using a crystal filter with
greater bandwidth than the DSP filter you're measuring.

Just remember the K3 has 2 filters:

Input > XFIL roofing filter > DSP WIDTH filter

If you want to check either, you must set the other so it does not interfere
with the overall measurement.  To force a specific XFIL, you must disable
all other XFILs...just remember to reset them when done!

Yes, that's the right way to do this.  


And, after the code is written to read the encoder this way, apply it to the

I'd much rather spin the knob fast and have the rig accelerate tuning (like my

Who knows?  It could mean someone's dyslexic and wrote 2.39 instead of 2.93. 
It would take me less time to check it than I've spent writing emails about
it!  All you need is a steady signal source like the XG1 since there's a
meter internal to the K3 with 0.1 dB resolution.  Just remember to set WIDTH
to maximum (which takes the DSP filter out of the equation), set the
internal meter to 0.0 dBV in the filter center, and note the frequency
difference for both -6.0 dBV points.

Unnecessary speculation? Unnecessary as far as you are concerned, perhaps,
but not for me. The figures quoted in the Wiki weren't obtained by measuring
*my* filter. And I don't have the equipment to easily check it. What else
might the "2.39KHz" mean?

That is also how I use the headphones: constantly jumping between them
and speaker. When I replaced the jack on my K2 I decided to add a
headphone/speaker switch on the rear panel. I can switch back and
forth between headphones and speaker with no worry about wearing out
the jack. 

But apart from the durability issue, the headphone/speaker switch is
amazingly more convenient. Some commercial grade receivers have this
feature; not sure if there is any ham gear which has it.

Doesn't the K3 have a 1/4" jack (vs 1/8")? That alone will make it a
lot more durable. Still, sure would like  to have a headphone/speaker
switch. I guess my question would be: how strong is the insertion
force on the jack? If it's more than about 4 or 5 pounds you will have
to hold the radio down to plug and unplug it; IOW, a two-handed
operation.

There's a difference?  Oh, wait, you said GOOD.  Yes, there's a
difference.

LOL!

Actually, I like reading the QST reviews but I find I have to read
between the lines and take things with a grain of salt.  There's good
info in there but you have to be able to sift it out.

Rob Sherwood will publish a detailed technical evaluation long before ARRL
(sans fluff).  Rob also is not afraid of offending advertisers by
identifying genuine problems.  ARRL's Expanded Test Reports are very
worthwhile but I would rather read good fiction than most QST product
reviews.  :-)

Perhaps so, but it creates a problem if my filter is actually a bit narrower
than 2.7KHz. There was actually "2.39KHz" written on my filter PCB, as well
as the sticker specifying the offset. I don't know if this is the actual
bandwidth that was measured when my filter was tested. The manual doesn't
say anything about this. But it's a good guess that's what it is.


I seriously doubt it since the 5-pole has been measured at >2.9 kHz (6 dB
BW).  It's easy enough to check without unnecessary speculation.

Perhaps so, but it creates a problem if my filter is actually a bit narrower
than 2.7KHz. There was actually "2.39KHz" written on my filter PCB, as well

bandwidth that was measured when my filter was tested. The manual doesn't

If I understand what Lyle told me by email yesterday correctly, if the
filter is narrower than the value set in the configuration then adjusting it
for preferred audio on one sideband may result in too shrill audio on the
other. Altering just the offset will make the good sideband worse in order
to make the other one better, which is exactly what I found. In order to
make both sidebands good, I need to be able to alter the other variable,
which is the bandwidth. Only I can't, because of this lockout.

Maybe not, but I believe the firmware is set up to allow SSB and CW TX
**ONLY** through the 2.7k 5-pole or 2.8k 8-pole.  If you set 2.4 kHz it will
not allow TX.  This is why EVERY K3 must have either of those two filters
installed and why you must not try to fool it by setting "FLx BW" lower than
2.7k.  

FYI, I tried using the 1.0k 8-pole on CW (before this option was locked out
by firmware) and I got a *worse* key click report than when using the 2.7k. 
So there are good reasons behind Elecraft's lockouts.

RE: [Elecraft] [K3] QST Labs review? -- Pool?

I suspect they're not jumping in there as part of the early-adopters
crowd.  I'm guessing they'll order their rig in a while, receive it in
late spring and will have the report in the Nov 08 issue.

How about a pool? 

My guess is the K3 review will appear in QST for December, 2008.

Anybody else?
