Re: [Elecraft] K3 AF PA

[Bob W9RFS]

I did a little more reseach and found the power amp for the speaker output in
the k3 schematics. The device is a LM4950TS. Here's a link:
http://www.national.com/pf/LM/LM4950.html#Datasheet  
Looks like 3.1 watts into four ohms with less than 1% THD. Is this correct
or am I missinterpreting the specs? Thanks,

[Elecraft] K3: Need 6kHz filter for wide AM BC reception?

[KM5Q]

To receive AM shortwave broadcast (at bandwidths wider than 2.7), do I  
NEED the 6 kHz roofing filter?


The price list seems to say I only need it to transmit AM (which I  
don't intend), but it isn't completely clear. The manual doesn't  
mention it.

[Elecraft] K3 memories

[Peter ZL1PWD]

Am I missing something or is it buried somewhere how to save memory channels 
including the power setting;perhaps also filter settings as I have not taken 
note of that?

It does gets a bit tiresome adjusting power settings when changing between SSB 
and the digi modes where I like to limit my power to about 20 watts.

I agree with other posters who have commented on being able to load memories 
via the com port and with different configurations loaded it would be possible 
to have unlimited memories over all portions of the HF spectrum.

Just a couple of thoughts from ZL

Re: [Elecraft] K2 #6425 low/no sensitivity - suggestions?

[TF3KX]

PROBLEM SOLVED.

I found a "full size" MC1350 at a local electronics store (the last one they
had, back in old storage...).  Replaced it for the modified SMD-version
MC1350 I had received from Elecraft - and this fixed my sensitivity problem!

I still don't feel comfortable with the low 8V level, but will leave it as
is for now and probably get a replacement regulator when I'm done building
the K2.

Hope others will learn from this.  73 - Kristinn

Re: [Elecraft] Solar power for the K2

[Paul]

Andrew,
When reading the other posts and seeing those large Solar Panel 
wattages, I think they are using a K2 but with the 100W option. I 
can't imagine needing a 33W solar panel to power the base K2 model. 
On a nice day, I guessing you could hook up a 7 Ahr gel cell and have 
it charged with a 5-10 Watt panel and work for a long time. The 
battery supplies the TX power when you need it and during the RX 
cycle the Solar Panel is catching it for power used.


You might try posting your question on the Yahoo QRPSolarPower newsgroup.
73,
Paul

Re: [Elecraft] OT - Botnets - the growing threat

[AJSOENKE]

One of the courses I teach is Computer Repair and Service. My students  
recycle about 200 donated computers (PCs) per semester. They are redistributed  
to 
needy families locally.  We have just migrated to Windows XP on the  newer 
donations with fast processors and larger  (>  256MB)
 
But, for at least 4 years now we have been distributing computers with  
smaller RAM and CPUs that started at 166MHZ. I'm currently cleaning out the 
last  
of about 50 Gateways with P3450s and 128/256 RAM.
We have run Windows 2000 (Win2K) exclusively on these computers (100s of  
them) with no problems. Also, it may be of interest top know that the 
recipients  
have been getting a full suite of software installed, all of it except the 
O/S  is freeware like Open Office. The only computers that have been slightly  
problematic are some HP Pavillions that need to have a special prep performed 
on  the HD so they accept the O/S gracefully.
 
We do have one advantage on the O/S because of the use of these computers  
being charitable in nature we have a free license to install Win2K.  There  is 
a 
way around this  for the general public. If they acquire a PC that has  a 
Win2K sticker in tact, they can legally install the O/S if it was  originally 
purchased legally.
 
For most users, they will find Win2K runs as good as XP with virtually no  
problems - and miles ahead of Win9x.  If you install Win2K you should also  
make 
sure to download and install SP4, to make it current.

[Elecraft] 50MHz Transverter

[Phil Theis]

Given the following setup: K3 using transverters, with 50MHz transverter 
set for xv1.
When I enter a 50MHz frequency via the com port the built in 50MHz 
receiver is selected.  I then have to band up once to get to the xv1, 
then I can successfully band up to 144 etc.  If I enter a 144 frequency, 
it immediately goes to xv2.
What would it take to get a serial command to go to a frequency in 50MHz 
range to go directly to the xv1 selection?

thanks

Re: [Elecraft] New Contest Transceiver

[Sandy]

The Japanese seemed to have gone "ape" on whistles and bells on the new 
radios!  I enjoy some contests, but the "contest" thing has gotten way out 
of hand to my thinking.  On weekends, what used to be "normal" ragchew 
get-togethers have gotten to be battle the contesters for a space just to 
"talk"!  I have also seen a lot of talk about computer controlled automatic 
"loggers" that also answer calls and make your contacts for you with little 
intervention.  What's the challenge there?  I do enjoy some "sprints" on 
QRP, but there are too many contests nowadays for a fellow to find a spot on 
the band to "shoot the bull" like we did in the "old days".


Since the FCC decided to throw away Morse code, courtesy has all but 
disappeared, and contests have almost totally taken over.  There is little 
places to go and have a CW QSO anymore.  Most of the CW ops nowadays seem to 
be contesters so you either join them or stay off the air.  There seems to 
be no place to go anymore on HF.


I don't think I will be even thinking of buying a K3 or especially an 
IC-7700 unless I win the Lottery now.  It's hard enough buying gasoline to 
attend hamfests now.

I'm sorry to sound like some kind of whining bitch, but, is it me, or is 
amateur radio fast becoming a pissing contest of sorts to see who has the 
flashiest rig at the cost of a new car. I for one refuse to spend that 
amount of money on a hobby I know I'll get alot of fun out of. I'm not 
completely sure about contests and what place they hold within the amateur 
community, but I'm sure there's a place and a reason for them. hell, I 
might even try my hand at a couple when I finally gain me ticket.
you don't need the latest icom or kenwood or yaesu, which you'd have to 
take out a mortgage to own, half the fun as far as I'm concerned is 
working with what you have. and sometimes, that might be a pile of cow 
shit, some duct tape, fencing wire for a feeder and a couple of aluminum 
coke cans for a matching circuit, and an old valve radio that's been 
beaten to death and still manages to put out it's full power. if the above 
works, why change?
me, I'm all for having a nice long chat with the fellas and working a 
little dx occasionally. I use to like to do that on the chocolate box but, 
there's too many fools there for that to be any fun anymore.

sorry if I sound whiney but, yeah there you have it, my 2 cents worth.

Not news.  IC-7700 was announced about the same time (i.e. Dayton last 
year)
as the K3.  You too can spend twice as much as a K3, with no Sub RX and 
get
worse performance.  I'm sure the contest gang will gobble these up...NOT. 
You could buy 2 fully K3s outfitted for SO2R for less than one

it sure is pretty!  ;-)

[Elecraft] K2 - initial alignment - No Side Tone (more)

[John Hoaglun]

Gary sent me some notes about the STL U6-25/ U8-4 setup to no avail. (I 
was already testing this with Scott after Googling around for notes on 
this issue.)


After flipping through the back of the book there are some more 
troubleshooting steps.

--U8-4 looks fine
--Q5 (2n7000) looks fine
--The AC Vrms on pin7 of U10 is low.

I then flipped to the voltage reference table for the Control Board and 
started testing the pins for U10. DC Voltage on pins 1,2,3 are all low 
and virtually nonexistent.  Pins 4,5,6,7 all test out fine.


When I look at the schematic for the control board in Appendix B It 
looks like U10 is quad op amp. It looks like the U10B portion of it is 
providing the signal to U9. If the U10B voltages all look fine where 
should I be looking next?


Scratching my head.

Re: [Elecraft] Soldering after Crimping

[Eric Scace K3NA]

  At the W1KM station we have had Anderson PowerPole connectors in 
service for about 4 years.  All were installed with the proper crimping 
tool.  The crimps were not soldered.


  We are starting to see some increase in resistance on some of the 
connections, and have speculated that some oxidation is occurring inside 
the crimped bundle of wires.  Typically 5 connections exist between 
source and sink:
  -- inside the power supply, between the board's wiring harness and 
the external terminal.
  -- between the supply's external terminal and a cable run toward the 
operating position.
  -- at the other end of this cable run, where it connects to a 
RigRunner (PowerPole).
  -- at the start of a second cable run, where it connects to the 
RigRunner.
  -- at the other end of this second cable run, where it connects to 
the radio.
The resistance of these connection, plus cable resistance and current 
draw, determine the voltage drop between supply and the radio's connector.


  To me, it seems a reasonable precaution to allow solder to be wicked 
up into the crimp from the front (not the rear) of the PowerPole pin.  
Properly done, this does not melt insulation nor cause the wire outside 
the housing to stiffen.

[Elecraft] Bandpass Filters for K2 & K3 IF for Softrock

[Jack Smith]

There's been speculation on whether an external bandpass filter between 
the Softrock receiver and a K2 or K3 is advisable to keep unwanted 
signals out of the Softrock.


I don't have a view on that other than to note that as Lyle commented, 
Larry, N8LP, has found it necessary or at least desirable to include 
such a filter with his planned LP-PAN unit.


I built a prototype Z10010-K3 bandpass filter today and posted 
performance data at 
http://www.cliftonlaboratories.com/k3_if_bandpass_filter.htm. Similar 
data on the K2 version of the filter Z10010-K2 is at 
http://www.cliftonlaboratories.com/K2_Filter.htm.


These filters are difficult to offer as a kit, as the inductors require 
careful trimming and the filter has four (interacting) trimmer caps that 
must be carefully adjusted to provide the desired shape and center 
frequency.


If there is sufficient interest, I will consider making both the K2 and 
K3 versions available in an assembled and aligned filter, with kits 
available only to those with sufficient test equipment and experience to 
successfully complete the kit.
Anyone interested in one of these bandpass filters should drop me an 
E-mail off-list. If there is sufficient interest, I'll consider a 
production run.

Re: [Elecraft] Soldering after Crimping

[KBG Luxford]

This may be a dumb thing to do, but after crimping (using the more 
expensive ratchet type crimper) and inserting the connectors into their 
housing, I run some hot melt glue around the conductors where they enter 
the housing.  This IMHO provides support to the conductors where flexing 
may tend to cause failure after a time.


I would be pleased of anyone could provide reasons why this is a stupid 
idea to put their argument on the reflector.  We learn by mistakes and 
by discussion!

[Elecraft] K2 - initial alignment - No Side Tone

[John Hoaglun]

I am on page 46 of the K2 build instructions.

I am unable to here the side tone with either headphones or a speaker. 
Using a DMM and a stereo 3.5mm connector I validated that  the J2 
connector on the RF board has good connections. I also checked that the 
tip and ring are not shorted to ground. When I power cycle the radio I 
hear a slight audio pop which indicates that amp is sending a signal to 
the headphones.


I have gone into the STL menu and toggled the U6-26 and U8-4 setting. 
With the STL in the 200+ range I am still not hearing any side tone.


U8 voltages all look good. The other functions so far all appear to be 
checking out properly.


Any suggestions for what to do next or where to investigate?


Thanks, JH

[Elecraft] K3: BM10 & HC5

[DOUGLAS ZWIEBEL]

John:

I've cc'ed the list because the BM10 and HC5 are pretty common and
perhaps would like this info as well.

First, I was not able to "set it up" by listening to myself.  I
engaged the help of a fellow contester who I have know since 1968 or
so.  We were both young teenagers at the time, so neither of us are
too senile yet.

He is an Audio Guru type.  His company supplies some high-end audio
stuff to those that think like he does.  He has a GREAT ear and is
very learned in this area.

Here is how he had me set up my TX EQ for best (smoothest/flattest)
sound with zero COMP.

EQ1 = -16
EQ2 = -8
EQ3 = +3
EQ4 = flat
EQ5 = flat
EQ6 = -3
EQ7 = +3
EQ8 = flat

He said that putting any power into band 1 and too much into band 2
was a total waste

Also, after setting all this up, I he found that setting the COMP to
20 or even 25 was "good" for contesting.  As I said, he also a
contester, has operated with me for many years at a world-famous M/M
back in the 70's, and he just loves phone.

With all the EQ=flat, I did feel "weak" when calling guys (hard to get
through).  Now, I feel like I am QRO (I run qrp) on SSB.  I'd say it
works well.

Again, I trust him.  He knows my voice and he knows what works for
contesting.  Obviously, YMMV.

[Elecraft] Re IC-7700

[Robert Allbright]

big MINUS, nothing for me, sorry ;-)

Yes the IC-7700 does have a cw auto tune button which helps to make  
cw netting very easy, the 756 PRO 3 does not have this facility.

The IC-7700 does have a twin-Pass Band tuning facility.
I have played with the demo radio at Martin Lynch for several hours  
and am very impressed by it.

I like to play with these modern radios.

[Elecraft] Ref Oscillator Calibration procedure not working after 01.77 Firmware install

[Mike Scott]

I downloaded new firmware 01.77 and 01.58 and I wonder if something has been
introduced to make CONFIG:REF CAL procedure not work.

It worked perfectly before using zero beat method.

I set frequency to 10.000 MHZ, CW mode 2.8 KHz Bandwith, WWV is good S9
signal

I set monitor to approximately equal volume level of WWV, monitor set to 36

I use MENU button to switch to CONFIG:REF CAL, so far so good, reading is
49.379.670

I tap SPOT; VFO B display changes to SPOT, here is where the problem creeps
in. I hear the spot tone and no WWV signal whatsoever. I can adjust VFO A
until the cows come home with no change as there is no signal to beat with.
I tap SPOT again and WWV is there but no spot tone. Toggling SPOT
alternatively gives me either the spot tone or WWV signal but never both
simultaneously. The display toggles from SPOT to REF CAL. It is really clear
when the WWV signal goes away.

Now when I exit CONFIG mode and tap SPOT I immediately get the beat tone of
WWV beating with the spot tone but I can't adjust the oscillator in normal
mode. I can zero beat the oscillator by trial and error by listening to the
beats in normal receive mode with SPOT enabled and then shift to CONFIG mode
to tweak the oscillator and back out to normal mode to see if I got closer.

Either I am having a gross operator problem or something has changed.

[Elecraft] New Contest Transceiver

[W7is]

After reading the owners manual on this new 7700 
rig,  the only  thing I found unusual is the  
Auto Tune feature on both CW and  AM.

Beside being large & heavy with no sub  receiver --  another  downer is
the 4 large  fans and the  potential to be very noisy like some of their
other gear.   

HRO is offering it on pre release special for  March.  If you 
click on the rigs picture, it will provide you the  details. 
Its not too likely they will peddle very many of them unless
someone becomes awe struck by the Spectrum Scope.  
Lots of wiz bang --- if you get caught up in it  :-)

[Elecraft] selling K3s, buying 7700's - PLEASE READ ME

[DOUGLAS ZWIEBEL]

Gee whiz...you guys are KILLING me...so many "ugly" private emails.

My posting was a JOKE.  I signed it with "KR2Q/tic."

TIC = Tongue in Cheek.

I can understand some non-native English speakers missing this, but
holy cow guys.  Haven't you read enough of my previous posts to know
that I'm in love with the K3?  My picture has been in NCJ and CQ with
my ELECRAFT rig (K2) clearly (prominently) displayed.

To sum up, my entire previous post was SARCASTIC.  It was a jab at
Icom for spending more money on their brochure and photography than on
design of useful circuitry.  And yes, I saw their rig in person last
year outside Contest University at the Crowne Plaza.  As a "contest"
rig, it was a joke then and it is even more so now that the K3 is
available and has demonstrated its superior RX performance via
Sherwood and ARRL testing.  Icom's 3kc roofer is really almost 6kc
(per Sherwood).  You gotta be kidding...buy a 7700?

Only ONE guy sent me an email noting that my timing was off by two
weeks.  He GOT it.

You guys need to lighten up a little!

Re: [Elecraft] KXV3 clarification requested

[K3KO]

Alternative is to build yourself an external box which switches in the RX
antenna for RX and to the xmit antenna for xmit.  You can use "key out' to
orchestrate this.  

Have had to do this with quite a few radios that did not have RX antenna
inputs.  Mine uses a large reed relay and thus rapidly performs this task.

Re: [Elecraft] PRO II vs K2

[David Wilburn]

Lots of great points brought up here.  The K2 is not all things to all 
people, it is a focused rig.  You bring up the point about the CW 
pitch.  That is an annoyance at times.  But it is like the band pass 
and filter adjustments.  The bad news is that you have to do them. 
The good news, is that you get to do them, and within reason, you can 
set them up how you choose.


That is one of the things I liked about the rig when I chose it.  I 
was looking for a rig that did CW better than the others, and had 
impressive filters that I could adjust to my tastes.

The K2 is better with close strong signals, and if I was back packing, I 
would rather have

the K2!
But as a rig that stays in the shack, I would rather have the pro3 over 
the K2

for every day use.

I got my pro3 for $2500.00 new, they go for about $2200.00 used,
a pro2 (I never had one of those) is about $1500.00.

If one compares price, you have to order every option on the K2,
the only option on the pro3 is the voice recorder I think.

In my book, they trade off low noise and distortion for convenience
on these new rigs, you get very stable accurate easy frequency control,
with whatever tuning speed you want, at the expense of digital hash
and distortion.

This isn't aimed at Brett.

When I built my K2/100 2 years ago I spent right at $1800. This included
EVERY module made for the rig except the 60m/transverter and noise
blanker. It also included a KAT100-1. Including the "cost" of ones time
in the price of a kit is ridiculous.

Yes, the Pro III has the pretty band scope and a bunch of "features".
Anybody who's really honest about it would admit they use 25% of those
"features" on a daily basis and probably don't know what the other 75%
really do or how to use them. But hey, they're in the rig. Ridiculous!

There seems to be two trains of thought when it it comes to rig design.
Lot of pretty lights, lots of wee small knobs and buttons, "That rig
sure does LOOK like it's worth the price", versus competent simplicity.
In the case of the K3 more than just competent.

There is no argument that the K2's receiver is better than the ProII/III
So, we have a rig which costs 40% less than a ProIII with better
performance, sans the pretty lights (I wonder how we got by without them
for 75 years), and it gets talked about like it's a sows ear instead of
a silk purse?

Come on.

[Elecraft] SignaLink USB and K2

[Matt Patterson]

Hi,

I have a Signalink USB and would like to use it with my K2 which has a 
8pin mic connector and is wired up for a Kenwood mic.  My question is, 
do I just use the kenwood pinout for the SLUSB?  Is anyone else using a 
SLUSB with their K2?  If so, how do you have your it jumpered?


Thanks,
Matt

I would say the K2 is better than the pro2, not quite as good as the pro3.
The pro 3 was improved quite a bit, the noise reduction really works well,
as do the filters, its not as bothered by close in signals as the older 
units,
and its got less noise, but still quite a bit compared to the corsair I 
have.


The functionality of the pro3 is VERY good, triple band stacking registers,
just push the 80 meter button three times and go through 3 different 
settings,

cw, ssb and am, the rig remembers all the settings, which antenna,
and tunes it, the filters, frequencies, etc, and it does that for every 
band.
Another thing I really like about the pro3 is tuning in an ssb qso, very 
often
the frequency is spot on, like within 1 cycle! I find that the other 
stations are also

right on frequency, no guesswork...

Another thing I was surprised about was the auto notch.
It will follow a signal around and notch it out, and an ssb qso
is 100%, and does not even sound bad!
Does the K3 do that?

AM reception is quite good, although the high end rolls off
early no matter what filter you use.
I never tried it on FM.
The K2 is ham band only, the pro series does general coverage and 6 meters,
and gives 100 watts out on all bands and frequencies ,and does 160 meters.
On CW, changing the pitch is turning a knob, it does everything, and is 
its own knob,

in the K2, changing the pitch requires redoing all the filters

With the band scope, the pro3 is a lot for the money.
It does have the usual 70mhz 1st IF problems, but much less then
the older ones, and the usual noise and poor audio output, but that is
also much better than the old ones.

You cant build an Icom though

The pro 3 is now about $2500.00 new.

Re: [Elecraft] Solar power for the K2

[WILLIS COOKE]

Ken, I show a 33 watt solar charger in Northern Tools
that is $299.99 and 38"X11-3/4"x1" and 13 lbs.  Doable
in a car, but a bit big for back packing.  Also
pricey.  It does not include a controller at that
price.

So, do I need to add a $100 KXV3 to my order just to get the RX ANT
feature, or will this functionality be added to the firmware?  That
is, when you only have a K3 and KAT3, have the ability to TX on one
antenna port, and automatically RX on the other antenna port?

[Elecraft] Solar power for the K2

I got into some wrong notes this morning. 600 MA is the amount adding 
the KPA-100 adds to the K3 during key down or transmit conditions. My 
earlier measurements were the right ones. I have the larger solar 
controller from Don Brown KD5NDB  and it works well with an AC power 
supply I use to keep my battery charged. I have been using this for 6 
years and now wonder if any advances have been made in solar cells so a 
ham can use them. I looked up a 70 watt solar panel on the internet and 
it was $500. I can't justify that and don't have any idea if it is even 
small enough to take car camping. Does anyone have any suggestions for 
solar power or do I just need to buy a second large battery?

That was what I was told by Steve G4JVG (now 9M6DXX), the editor of RadCom
at the time. My review of the K2 was a result of a chat with Steve over
lunch at one of the RSGB HF Conventions. Bob G3PJT, then President, added
his own section to the article before it was published.

I look forward to seeing a K3 RadCom review in due course - not from me, cos
I ain't got one... (but just received a K2/100 and K1 from a friend for
checking out).

RE: [Elecraft] wattmeter calibration

[AD6XY - Mike]

I have now fixed my problem. RFC1 was not soldered in properly. At first,
after much debugging of the schematic I thought it open circuit. It was only
when I came to remove it that it became clear what had happened. One end was
not soldered at all. A common problem with these large SMT inductors.

Here are my power readings for 5W calibrated at 14.15MHz made with an HP435B
and a 8484A head. Please note this head is only specified down to 10MHz -
though it does work below there.

80m 4.7W
60m 5.0W
40m 5.5W
30m 5.9W
20m 5.0W
17m 5.0W
15m 5.5W
12m 5.5W
10m 5.4W
6m  5.5W

All to closest 0.1W. The maximum error appears to be on 30m at nearly 20%.
This is pretty good, but you can not rely on the set power to be exact.

For the 1mW setting from the KXV3, I only checked in a few places as I
really only care what it is on 10m. I was able to set it to 1mW. At that
setting the 1.5mW meter gave 1.5mW out. Pretty good. The accuracy degraded
below 1mW, so 0.5mW power indicated was actually 0.6mW with things getting
worse at lower levels. The minimum power output was around 0.2mW.

I would like to look at the IMDs at the 1mW output, but I don't have the
equipment for that at home.

Mike

Re: [Elecraft] OT - Botnets - the growing threat

[Leigh L Klotz, Jr.]

A good thing to do with older computers running Win98 is to try one of the
small versions of Linux designed for ham radio use on older computers. 
Dave W1HKJ has bundled digimode and logging programs onto a CD-bootable
version of Linux that runs great on small machines.  I just tried it
recently on a 366Mhz Thinkpad.

You can boot from CD, and to do an upgrade, boot from a new CD.  It can
store your settings on the existing Windows disk, so you will have your
log files and data stored.

Or if you decide instead to replace Windows 98, you can install it
directly and update it with new releases of the software with a few mouse
clicks.

Give EMCPup a try at http://w1hkj.com/emcpup.html or at least look at the
screenshot.

It includes:
- fldigi, the premier Linux digimode program (same DSP modems as in Ham
Radio Deluxe's DM780) now with K2 and K3 support
- fl logbook
- flarq (an ARQ-based soundmode program)
- plus the usual email, browser, etc.

Leigh/WA5ZNU

P.S. I've contributed a few features to fldigi itself, but tried using
EMCPup until recently.

[Elecraft] Review of Elecraft K3

[G8fmh]

Peter,
 
I spoke briefly with you at the HF Convention last year in the Ten-tec  
presentation. Saying that I was willing to make my K3 available to you for  
test. I 
have now had the radio for a couple of weeks and am very pleased  with it. It 
includes three filters, 2.8k 5-pole, 1.8k 8-pole and 500 5-pole, and  a MH2 
hand microphone. There is no KAT3 tuner unit because I need an external  tuner. 
Of course I am still waiting for the KDVR3 and KRX3 with a 2.7k 8-pole  
filter.
 
If you are interested please email me to arrange a meeting and loan of the  
rig.

[Elecraft] Cost of Fully loaded K3

[Bill Tippett]

I wrote:
>You could buy 2 fully K3s outfitted for SO2R for less than one IC-7700

KK7SS:
>I started wondering just how much a FULLY loaded K3 would cost...
Stuffing a K3 with EVERYTHING(!) including 10 top-of-the-line roofing
filters in Kit-form I came up with $4469.65 + shipping
Or about $2,000 less than one IC-7700

Outfitted for SO2R does not mean fully loaded.
For starters you don't need a KRX3 in either radio since
SO2R means you have two separate radios.  You definitely
don't need 10 filters...more like 2 extra per radio beyond
the standard 2.7k (e.g. a 1.8k for SSB and a 500 for CW).
Most serious contesters don't need an ATU because they
use amplifiers with tuned inputs and/or resonant antenans.
And most don't need a KDVR3 because they use DVK in their
computer.

So what would a SO2R capable rig cost?

K3/100 - $2090 assembled ($1850 kit)
KXV3 - $100 (necessary for RX ANT & IF OUT)
KFL3A-500 $100 (500 Hz for CW)
KFL3A-1.8k $125 (1.8k for SSB)

Total - $2415 ($2175 kit)

Double for SO2R - $4830 ($4350 kit)

IC-7700 - $6300 (Ham Radio Outlet online price)

But you don't have a bandscope?  On
one K3 add $200 for N8LP's LP-PAN IF buffer
and add Rocky or WU2X's PowerSDR (both free).
Add $1000 for a dedicated P4 computer and
LCD display.  This provides a true SDR display
(like Flex 5000) which will run circles around
traditional bandscopes.  Now we're up to $6030

Want a bandmap of mults for your S&P band?
Add another $75 for VE3NEA's CW Skimmer.  Now
you have a contest package of incredible
performance for $6100 or $5600 kitted...about
the same as the street price of one IC-7700...
but it's pretty!  :-)

[Elecraft] Report for Elecraft SSB Net - Monday night March 17

[Roger Stein]

Good morning,

Seven (7) check-ins were in the log by the time signals had faded away at this 
QTH, WA.

I had the tree removers in yesterday to clean up the final remnants from the 
storm of last
December. Namely, the 'widow-maker' branches hung up high in the trees!! 
So...while they were
on site with a 70' lift basket...I had them trim out the interfering branches 
in two of the
trees that kept me from getting my full-wave loop into final position. Just one 
antenna tree
left that requires some branch trimming, climbing spurs required!!

The check-ins:

AE4LD - Larry - NC - K3 - #102... Nice signal, beam and a KW!
WA6OCP - Neal - CA - K3 - #305
K4JAF - Jim - FL - K2 #5778 and K3-in-waiting, must be getting close?!
WB8YQJ - Don - CA - K3 #272 took a while to get Don's call out of the nosie!!
KE5WY - Jim - KY - K3 #356
NT1R - Bill - ME - K3 #124, thanks for the relay Larry!!
KI6JJT - Robert - CA - TS-430

Thanks to all,

[Elecraft] Cost of Fully loaded K3

[Dave G.]

After reading this...

""You could buy 2 fully K3s outfitted for SO2R for less than one IC-7700""

I started wondering just how much a FULLY loaded K3 would cost...
Stuffing a K3 with EVERYTHING(!) including 10 top-of-the-line roofing 
filters in Kit-form I came up with $4469.65 + shipping
Or about $2,000 less than one IC-7700
Both of which are way beyond my budget...
But a basic K3/10 with a KXV3 suits me just fine  ;-))

Thinks...I wonder if the K2's internal battery would fit inside the K3??
H!!

Re: Subject:,Re: [Elecraft] KPA3 for QRP

[Robert Tellefsen]

Hi Kenneth
A couple of people have measured their K3s
without the KPA3 and again with it.
The difference seems to be as follows.
In receive, no difference with or without
as far as current drain goes.
When transmitting at QRP levels with the
KPA3 in bypass mode, the TX current
drain is approx 600 mA more than if the
KPA3 were not installed.

So, for a base station with an ac power
supply, no big deal.  However, for a Field
Day rig, if you plan to run a QRP entry, those
extra 600 mA will all have to come from
your battery.  That either reduces the time
you can operate from that battery, or cause
you to change batteries sooner than you
would have to otherwise.

That seems to be the essential difference,
Kenneth.  I had hoped to use my K3 (still
to come) on FD, but I think I'll stick with
my K2 at 5W.  Much easier on my battery
and solar panels.

73, Bob N6WG

Most publications worth reading (RadCom is one
of the very best) make a clear distinction between the
editorial department and advertising department.  Would
you even bother reading something that you felt was not
objective and had been "bought" with advertising?  I doubt
it.  Such publications would not be in business very long.

Re: [Elecraft] New Contest Transceiver

[Gary D Krause]

I agree with you also, Julian.  I've always thought keeping it simple is the 
key to many things.  I still have a couple of older rigs that I love to 
operate along with my K2.  They don't have the bells and whistles that the 
modern rigs have.  I've noticed that along with the computer age, the new rigs 
seem to have their own set of problems.  You can't tell if a person is using a 
high priced rig or a simple homebrew rig when it comes to CW.  SSB may be 
another story but, for the most part the focus is primarily on the receiver. 
Even then, the most important part of the station is still the antenna, in my 
opinion.


Gary, N7HTS



I see where you're coming from, Shaun, and I for one totally agree with you.
I think the simpler the equipment the greater the feeling of achievement. Of
course, a K2 or K3 is not exactly simple. I have an MFJ Cub transceiver that
I get out from time to time and I really get a kick out of the QSOs I make
with it. I'd probably use it more if I wasn't embarrassed by the fact that
it drifts rather a lot (and I lack the time, patience, knowledge and parts
bin to try to do anything about it.)

[Elecraft] Re New Contest Transceiver ICOM IC-7700 (W7IS)

[Robert Allbright]

This radio, the IC-7700 has just become available from Martin Lynch  
in the UK.
I've played with it and it is superb with an excellent display etc,  
however, you could purchase 2 K3s for its price, but it is much  
cheaper than the 7800.

It does have Twin-Pass Band Tuning by the way.

[Elecraft] KPA3 for the QRP enthusiast

[WILLIS COOKE]

Thanks to those who submitted current measurements for
the K3 with and without the KPA3.  I found the
information very interesting and I am not surprised
that the measurements vary somewhat depending on the
individual unit.  The measurements that I saw
indicated that the additional current drain was
between 200 and 600 ma. and applies only when the rig
was in transmit.  Even the most aggressive contester
will not be able to stay in the transmit mode 40% of
the time.  To this extent, the difference in drain
would only be important to those who need to carry
their entire station in one trip.  If you need to run
on a 6 to 10 amp hour battery, maybe it is important
to you

It appears to me that the most important consideration
is cost.  I will keep my KPA3 on order, but since I am
a QRO operator most of the time, that was never in
question.

RE: [Elecraft] New Contest Transceiver

[Darwin, Keith]

You guys have it all wrong.

The IC-7700 is CLEARLY the better choice.  No question.

K3 is $2000 - $3000.  I can *almost* afford that.  It's a great rig so
I'm tempted.  Ah, what the hey, I'll just order one.  Tension with XYL
ensues, finances are stressed, life becomes a bit more difficult.

IC-7700 is $937,295 (or some out-of-reach number).  It's not nearly as
good of a deal.  I'm not tempted.  No order is placed, no tension with
the XYL, no financial stress on the family.  In fact, not having one
means I don't even need an antenna or power supply or key.  That rig
would sure save me a lot of heart ache!

[Elecraft] Solar Controller Kits for Sale

[dolfindon]

Hi
 
 
I am kitting another batch of my Solar Controller Kits. There are two versions, 
a high power and a low power. The low power is good for about 40 watts or about 
2.5-3 amps and sells for $20. The high power version can handle up to 200 watts 
or about 15 amps and sells for $30. The kits include a circuit board and all 
parts required to build the controller. You will need to supply a box to mount 
the controller into or install it into your battery box. This controller works 
with a flooded lead acid or sealed lead acid (gel cell) with a current rating 
of 2 to 100 amp hours. Solar panels of 3 to 40 watts for the low power and 2 to 
200 watts for the high power can be used with these controllers. The controller 
is an analog design and does not generate any RF or switching noise.

Nice looking rig,

Howeverit still only has 1 receiver. Elecraft stated they will
eventually have a pan adaptor/bandscope option for the K3. If you've read
the recent test results, the K3 meets and sometimes, beats the 7700's big
brother. And to add insult to injury, I dare venture that one could purchase
2 fully loaded K3's for the sticker shock price of the new kid on the block.

Prove me wrong

Those statements are incorrect in almost every detail.

The Radcom review of the K2 was actually two separate articles by two

Now "taking a break" has somehow turned into "wasn't particularly

I don't know if Peter Hart has plans to review the K3 or not. But I do

The RSGB advertising department may try to sell space opposite a review

People talk about the extra current drain.  How much
is it?  I don't have my K3 yet to make any tests and I
seldom run QRP (only when the other station wants 2
way QRP), but it would be of interest to us all if
anyone had measured the current draw of the K3 at
receive with and without the KPA3, transmit at 5 watts
without the KPA3 installed and transmit at 5 watts
with the KPA3 installed. I am sure that Elecraft has
the information, but I don' recall seeing it
published.  My guess is that the KPA3 does not require
much if any current when it is switched out.  Anybody
do any tests to know for sure?
+
I measured my currents at the 12 watt part of my build 
and again when the K3 was finished.

on 14.05 MHZ I measured TX 2.73 amps as a 12 watt K3
On 14.05 MHZ I measured TX 2.93 amps as a 120 watt K3
The receive current is 0.9 Amps either way.
The receive current can jump as high as 1.1 amps if the
fans are running.

The extra 0.2 amps is only taken in transmit mode.
If the XMIT button is hit it takes the extra 0.2 once
the 120 watt amp is installed. If full break in is 
used than the extra 0.2 amps is only used when the key

is down. If you did a field day using S and P and full
break in the extra current would be about an extra 
half amp hour. If you were calling CQ at 50 percent

transmit and full break in it would be about an extra
two amp hours. If you hit XMIT each time it would 
add about an extra 0.5 amp hourto the two amp hours. 
The K3-100 in receive for a 24 hours field day

will use about 24 amp hours plus 5 to 24 extra amp
hours in transmit depending on duty cycle. That makes
a total of 29 to 47 amp hours for a full 24 hour field
day.

A K2 can do the same field day in about 12 to 26 amp
hours. I find the K3 to have so much better receiver
and I operate S and P so it will plan to spend the
extra 17 to 18 amp hours for my field day.

[Elecraft] Soldering after Crimping

[David Robertson]

If you have the proper crimping tool for Anderson Power Pole connectors ( not 
the cheap $30 Pair but the $50 or more pair with ratchet locks) the crimped 
connection should not be soldered.  Soldering the crimped pin results in solder 
wicking back up into the wire melting or damaging the insulation and causing 
the wire be very stiff at the point of entry in the Anderson pin. This could 
result in failure of the connection after some use.

If you don't have the proper crimping tool you must solder.

Dave KD1NA

Re: [Elecraft] KAT2 without balun - which doublet length is better?

[David Woolley]

ub5_073_oleg wrote:


I'm going to use my K2 with KAT2 internal ATU to operate a
doublet from 80m to 10m including WARC bands without a
balun. Among others, Dave's W8FGU home page inspired me to
try this.

I hope this is not a problem, especially when battery-fed
during portable operation, as there is [almost] no
HF-connection to the ground (the whole system is 'floating')


Even though the case is floating, it doesn't avoid RF on the chassis 
problems.  Although the output transformer will see 50 ohms, the two 
legs of your doublet will have a much higher impedance which means that 
the RF output will cause the chassis voltage to vary by much more than 
would be implied by assuming half the power into 25 ohms.  Instead of 
under 10 volts, you are likely to get up to 100 or so volts.  I've found 
that to my cost with a short indoors doublet on 160m, even though it has 
a simple balun.


The high chassis voltage variations will drive any appendages, like 
battery cables, key cables, headphones, etc.


Unfortunately, for baluns to work well they really need to be on the 
transmitter side of the ATU, where they see about 50 ohms differential 
mode, and that isn't compatible with an internal ATU.


My current best guess as to what is needed is to tune out the reactive 
component of the ground side leg of the doublet, and therefore get the 
impedance down to 25 or less.  Logically this is equivalent to end 
feeding against a counterpoise, but, in my view, the distinction between 
a counterpoise and the other half of a doublet is somewhat artificial.


I haven't tried this in anger, and one question is how to determine when 
you have canceled the reactance.  The instructions for commercial 
"artificial earth" tuners tend to suggest tuning for maximum current, 
but, it seems to me that that can only be done if the formal ATU is 
tuned to cancel the reactance in the non-ground end.  As that setting, 
in turn depends on having zero reactance on the ground end, one, has an 
interdepence problem.


My question is: can/should I make it easier for KAT2, e.g.
choosing other antenna or feeder lentgh or maybe
adding/removing a piece of feeder on some bands? Are there
some proven length to use? 


The G5RV was designed to have a relatively good match on all the 
pre-WARC bands.

Hmm,

if you adjust for inflation this new 7700 is a bit cheaper in real terms
in Europe than the Kenwood TS940SAT was at launch time.

the 7700 is a much better featured radio than the 940.

RE: [Elecraft] KPA3 for QRP

[Darwin, Keith]

But I think we missed the point of the original post.

I believe the question was not "how much dead weight is the KPA3 when I
run QRP".  That has been answered.  The question was "wouldn't the rig
be a better QRP rig if the KPA3 was used even at QRP levels?".

With the K2, current drain was an issue and shutting down the after
burner for QRP made sense.  With the less portable K3, current drain is
largely a non-issue so shutting down the big finals below 10 watts isn't
an obvious good thing in my book.

Of course, if I were smart enough I could just answer the question.  As
it is, I'm barely able to simple rephrase it :-)

Re: [Elecraft] New Contest Transceiver

[Shaun Oliver]

don't get me wrong, the newer radios have their place. case in point, 
the kenwood ts480 and the ts2000 with a vs3 board, a blind ham could use 
the things with little fuss. I will eventually be a blind ham also but 
I'm opting for an older radio because I'm on a strict budget. I'm 
currently looking at the yaesu ft201 and a 101b. I use to own a 101b and 
it wasn't a bad radio, but between that and the old 520 I use to own, 
let's just say I still miss that 520. I'm going to have a look at that 
201 this weekend so hopefully I'll be ready for when I get licensed. I'm 
opting for foundation license for now because it's quick and easy to 
obtain and I'm pants when it comes to alot of electronics and antenna 
theory.

sales brochure from Icom.  CLEARLY, it is the superior radio...you can
tell just by looking at the quality of that brochure.  I just KNOW
that their paper stock is going to be very heavy weight, super high
gloss.  It just screams QUALITY.  Did you see the close-up photography
of the toroids?  I mean, like WOW!

I'm CONVINCEDCUL Elecraft.

Re: [Elecraft] New Contest Transceiver

[Shaun Oliver]

I'm sorry to sound like some kind of whining bitch, but, is it me, or is 
amateur radio fast becoming a pissing contest of sorts to see who has 
the flashiest rig at the cost of a new car. I for one refuse to spend 
that amount of money on a hobby I know I'll get alot of fun out of. I'm 
not completely sure about contests and what place they hold within the 
amateur community, but I'm sure there's a place and a reason for them. 
hell, I might even try my hand at a couple when I finally gain me ticket.
you don't need the latest icom or kenwood or yaesu, which you'd have to 
take out a mortgage to own, half the fun as far as I'm concerned is 
working with what you have. and sometimes, that might be a pile of cow 
shit, some duct tape, fencing wire for a feeder and a couple of aluminum 
coke cans for a matching circuit, and an old valve radio that's been 
beaten to death and still manages to put out it's full power. if the 
above works, why change?
me, I'm all for having a nice long chat with the fellas and working a 
little dx occasionally. I use to like to do that on the chocolate box 
but, there's too many fools there for that to be any fun anymore.

sorry if I sound whiney but, yeah there you have it, my 2 cents worth.

Not news.  IC-7700 was announced about the same time (i.e. Dayton last year)
as the K3.  You too can spend twice as much as a K3, with no Sub RX and get
worse performance.  I'm sure the contest gang will gobble these up...NOT. 
You could buy 2 fully K3s outfitted for SO2R for less than one IC-7700...but

it sure is pretty!  ;-)

I am getting great audio reports from pretty much anything I have tried
with the k3 so far.

I bought on Ebay a very cheap skype headset. This is sounding really
good, not too much base and plenty of Presence, Nice clear 'DX' audio. 

like ebay Item 180224618274
http://tinyurl.com/2j5f6x

For a desk mic I tried an old computer desk mic that came with a gateway
PC years ago. Once again I am getting very good reports with this. I
have not tried any TX EQ settings other than flat.  

My home brew headset is based on a beyerdynamic headset and a copy of
Icom's hand mic circuit implemented in place of the original noise
cancelling dynamic insert. 
This has worked very well for me on a variety of radios, it also works
very well on the K3 

All of these connect into the mic in jack on the rear
I don't think there's is any magic here, pretty much any electret
condenser mic is going to perform more than well enough for excellent
SSB audio, No need to buy into any hype.
Mic housings with smaller openings will tend to have more Low frequency
roll off 

It's nice having everything connected via the back as it leaves the
front panel clear, since I Like changing things around I have routed all
the rear panel audio,ptt and keying lines via a 1/4" half-normalised
patch panel. This allows me to swap mic / change key etc with ease

I have a 250 in mine and find it very good it is wider than 250 but this
does not appear to be a problem. I have not tried the 200 however I am
entirely happy with the current level of performance which during the
CQWW and CQWW160 cw contests was very noticeably better than the icom
7800

[Elecraft] KANT3 with two SO239?

[Ian White GM3SEK]

Please can Elecraft clarify if there is any plan to upgrade the KANT3 
board to provide switching between two SO239 antenna sockets? (In other 
words, the same switching as the KAT3 but without the auto-ATU.)


Soon, sometime soon, sometime, maybe sometime, probably not, or never?

The answer will affect my order confirmation, Real Soon Now.

Hi Steve:

   I would very much recommend getting a Shure 444D desk microphone for 
your K3. I am using one with excellent transmit audio. It's a very simply 
job to connect the appropriate mic connector to it.

I know this sounds lazy but what desk mic. could I order, plug directly into
a K3 and operate with no wiring changes? Yes, a good one.
Which is better, the 200 hz 5pole or 250 hz 8 pole? Which is best for the
160m cw test?
