[Elecraft] K1 or KX1?

2006-06-21 Thread Jim Murray
Hello all,
Have been thinking about getting my feet wet with building either a K1 or KX1.  
I see most posts seem to refer to the KX1.  Aside from size and portability is 
there any difference in performance in the two?  I can work with either one but 
would prefer the one with best performance.  K2 next- can't find much that 
beats it.
Tnx, Jim/k2hn

[Elecraft] K1 or KX1 ?

2004-08-26 Thread KA4NRF
 Tried to post a what should I get question and it got dumped by the 
moderator, OOPS, sent from the wrong e-mail address. So I have decided to get 
the KX1, 
easier to bring with me to work and on trips. The special prices also helped 
me decide, So who knows, if I get ridd of my FT100, then I can get a K1 or 
K2?? We shall see whats nextMust be great radios with the following, 
Checked 
out the radio's at the  Orlando Hamfest in the past and now is the time to 
buy. Now I live and New England and have mountains to operate from...

The true correct answer is - both.  I have both and find each has it's

I built the K1 first...used it a couple years, sold it, bought a already built
KX1.

Both are fantastic rigs.  I miss my K1 and the 5w output though.

I think this fall I will buy another K1 and build it.

I will keep the KX1 for a long time, it fits in my shirt pocket...best camping
rig I have ever had.

Re: [Elecraft] K1 or KX1?

2006-06-21 Thread David Toepfer
Just my opinion, not looking for an argument (when I asked this question, it
was the many opinions that helped me decide mrore than the arguments over who
is more right):

I chose just the KX1 because I wanted an easily portable transciever.  While
the K1 is that too, I liked the more all-in-one-ness of the KX1.  I also plan
on doing more experimenting in future, which many convinced me would be more
suited to the K2 because of more space available in the case and on the boards.
 But I still liked size and the simplicity of the K1.  It was then when I
started looking at the K1 and what I wanted it to do, and how much it would
cost me to get to where I want with it.  The K1 is almost 62% the price of the
K2, and the K2 is (according to most who actually own both) so much better of a
rig.

  fully kitted KX1: $502
  fully kitted K1 (w/ extra 2-band module): $611
  fully kitted QRP/CW K2: $982

I plan on getting a K2 in the future, so why would I want a K1 as well (though
many do and will).  And now, with the addition of 80m on the KX1, I am sold on
it alone.  There are many other reasons to like the KX1 more for me as well
(DDS and wider VFO range, SW BC RX coverage.

Of course, if I ever do get into mobile (car) QRP CW, I will look to the K1 to
fill that role.  It seems to me that it would suit it so well.

simple answer: K1

It goes everywhere, tunes to my portable antenna

everybody I know who owns one sez it's their

The KX1 is the "X"-treme portable rig. The whole station, key and antenna
fits in my jacket pocket. It gives up a few things for that. One is output
power. On internal batteries it is limited to 1.5 to 2 watts. So what's
that? -- about 1/2 or 3/4 "S" unit below a full QRP Gallon: 5 watts. Shoot,
I worked the world for years with my 2-watt HW-8, but it's still
significantly less than 5 watts. But, if you have room for an external
battery or power supply it'll come within a gnat's whisker of that QRP
gallon. 

I don't have a K1 so I won't comment on a direct comparison. The KX1 does
permit SWL-ing in the more popular SW broadcast ranges. Its internal ATU is
more limited in matching range than the other Elecraft tuners because of the
miniscule space it must fit into. That limits the number of inductors and
caps that can be used to produce a match. 

If you have a pretty normal-sized operating desk and never operate portable,
you'll like the K1 (or K2!!) much better except for the extended frequency
coverage provided by the KX1. 

If you like portable ops, must travel frequently, or live in a small R.V.,
you'll probably appreciate the KX1. 

As for sheer performance in terms of receiver sensitivity, selectivity, and
dynamic range, the K2 beats 'em all.

Each Elecraft rig fits a niche. And many of us have more than one niche we
want a rig to fit into, so we end up with more than one   

If you can tolerate a portable rig the size of fat hard-cover novel and want
the greatest flexibility, I recommend the K2. With a 2-minute cover swap you
can go from a QRO rig to a self-contained QRP portable station with built in
wide(r) range ATU that only needs an external key (and the KXPD1 paddles can
be used with the K2 using the special bracket Elecraft just announced that
clamps to the K2 bail) and an antenna. Back home, you drop on a different
cover and have a 100-watt 160-meter through 10 meter CW/Data/SSB station
that leads the state of the art in Amateur gear.

And people adverse to swapping covers have come up with a way to avoid that
and just plug the K2 into the home station with the KPA100 and KAT100 amp
and tuner in an Elecraft box that sits alongside the K2. It's all documented
on the Elecraft web site.

I have a K1 (bought someone else's) and a KX1 (built it, added KXB3080 this 
spring).

I won't part with either, they do different stuff.

The K1 is my all-time favorite radio, ever. 

Before I had Elecraft rigs, I had a Wilderness Sierra that I built -- that was 
my favorite before my K1. The K1 reminds me a little of the Sierra, but is a 
much more civilized rig. I just built an HF Packer amp, and the K1+amp 
combination is awesome.

It's a tough choice, but I really don't think you can go wrong.

As far as RF performance only goes, the K1 is clearly superior.

(1)  The K1 uses an LC VFO that is cleaner than the direct digital synthesis 
frequency generation scheme of the KX1.  This reduces transmitter spurious 
output, and improves receiver performance because fewer spur frequencies are 
part of the local oscillator signal fed to the front-end mixer.  In fact, 
according to reported measurements, the K1 has better transmitter spurious 
output specs than even the K2.

(2)  The K1 can be placed on any of the HF bands, though Elecraft currently 
sells parts for 80m through 15m only.  The KX1 DDS chip is clocked at its 
maximum rate of 50 MHz, which limits KX1 frequency coverage to around 20m and 
lower.  The 15m band is one of the best QRP bands when open.

(3)  The K1 IF uses a four-pole crystal filter, while the KX1 IF uses only 
three.

(4)  The K1's optional auto antenna tuner tunes a wider range of impedances 
than that of the KX1.

(5)  Most find the continuous LC VFO tuning of the K1 to be more natural than 
the step-wise tuning of the DDS in the KX1.

(6)  The K1 has a noise blanker option, while the KX1 does not.

(7)  The K1 transmitter can produce up to seven watts of output power.  The KX1 
is about half that.

(8)  The K1 case contains a speaker, the KX1 does not.  (The K1 has plenty of 
audio to drive it too.)

(9)  Personal preference...I like the front mounted controls of the K1 more 
than the top mounted controls of the KX1.

OTOH, the KX1 is clearly superior in terms of VFO stability...a DDS is about as 
stable as a crystal oscillator.  It is superior in its span of frequency 
coverage within the limits of the DDS.  It can switch between USB and LSB due 
to the frequency agility of the DDS as the local oscillator.  It has neat 
features like audio feedback to controls.  It is definitely smaller and lighter.

IMHO, the KX1 has many positive features that the K1 doesn't have, but none of 
them except VFO stability actually are improvements over K1 RF performance in 
the ham CW bands.  In overall RF performance, the K1 has the clear lead.

But...if the K1 were not available, the KX1 would be my very next choice for a 
QRP rig.

I too have the K1 and like it very much.  It is the 4 band version with a
KAT1 tuner added.  Also have a 2 band board that covers 160 and 80 meters.
Have done the backlighting modification and this was well worth
the effort!.
I too have an HFPacker amp I built.  It is an absolutely dynamite
"pair of shoes"
for the K1!  My only complaint is the "hang time" on the RF actuated T/R switch
is too long.  No good for contest use!  I tried it on the ARRL 160 meter 
contest last
year.  It's OK for casual QSO's but delay too long for CW.  One day I will get
that fixed.
Some day in the future, I'd like to build the K2, probably the QRP version.

[Elecraft] K1 or KX1? Backpacking Analysis

2005-08-02 Thread mvamis

... the KX1 wins handsdown for backpacking...



Strange!  Before the KX1 came out, the K1 was generally
acknowledged as the best multi-band backpacking rig
available.  It is no less suitable for that task today.


I think you misunderstand.  Let me look at your comments 
one at a time.


   "If one is happy with the limited number of bands
   covered by the KX1"

The KX1 covers 20, 30 and 40 meters.  When one is talking 
about backpacking, they are spending a majority of their 
time hiking. Generally, and this will vary by person, a 
backpacker will hike during the day and set up camp during 
the late afternoon or early evening. I don't think that 
having the full spectrum of bands is going to add 
significantly to the hikers (aka ham's) enjoyment of his 
evening's operating, While it would certainly be nice to 
have a rig that was equipped with 10 through 80, I would 
suppose that only 1 or 2 bands would actually be used 
before it's time to hit the sack.


   "and recognizes that there is absolutely **no** 
physical
   way that KX1 receiver RF performance can match that of 
a

   properly constructed  K1 in any area other than VFO
   stability,"

There are others here on this list that would say the 
difference is very minimal. Since I don't own a K1, I 
can't comment.


   "and that the ATU in the KX1 can't come close to the
   matching range of the K1's KAT1"

Again, remember that the hiker is backpacking, and as such 
is carrying a small radio and minimal antenna.  If I were 
to hike today, I would take the KX1 with 25' of antenna 
wire and 16' of counterpoise wire.  Since the wire used 
would be very small, it would be light and compact. The 
KX1 easily matches that wire, once strung in a tree, to a 
perfect 1:1 on all 3 of its bands, which is all that is 
needed.  While it IS true the K1's ATU may be better at 
matching systems under more difficult situations, that 
capability is not needed when out doors with a 25' of 
wire.


   "On the other hand, if RF performance *on the ham CW
   bands* is important, the K1 stands as the best of the
   two."

I'm not sure how you justify that statement, but oh well.

   "I don't care that I can't use it for shortwave
   broadcasts or to copy the ham phone bands.  I've got a
   Sony portable that'll do that quite adequately, with
   essential AM/FM coverage to boot."

Are you needing to carry that too?  That is an additional 
weight and more hardware to pack that is not required with 
the KX1.


Specs that are important to me:

The KX1 is 1.4 x 5.8 x 3.0" and weighs 9 oz (excluding 
options)
It has a current drain of 32 mA on receive and 300-700 mA 
on transmit.


The K1 is 2.4 x 5.2 x 7.1" and weighs 1.4 lbs (excluding 
options)
It has a current drain of 55 mA on receive and 700-900 mA 
on transmit.


The KX1 runs on 6 "AA" batteries, and will output 1.5 to 
2.0 watts.
The K1 runs on 8 "AA" batteries (with optional KBT1 
installed) and will output 5 watts.


The KX1 comes with a small keyer that attaches directly to 
the side of the KX1.

The K1 requires a separate keyer.

Don't get me wrong. I am not trying to tell you that the 
K1 is in anyway a lesser radio than the KX1. In fact, I 
own a KX1 and I am seriously considering purchasing a K1. 
There ARE some situations where the K1 just would be a 
better "fit" than the KX1.


What I am talking about here is the practicality taking a 
ham radio hiking into the mountains. If I could carry it 
and the necessary hardware, I would love to hike into the 
woods with a K2 and a nice Buddipole. But being practical, 
I see the sense in having the KX1 as my radio of choice 
for backpacking, and thus the original statement...

[Elecraft] K1 or KX1? Backpacking Analysis -- comment

2005-08-02 Thread crmabbott
I can only say that 80 percent of my contacts are on 20 or 40.  So the number 
of bands covered by K1 or KX1 would not be an issue.  The rig I use as all the 
bands available but I have favorites and I am sure it would be similar with the 
hikers too??

[Elecraft] K1 or KX1? Looking mainly at receiver

2005-08-01 Thread Jeremy Cowgar
I am looking for a backpack rig (3-5 day backpacking trips). I know the 
KX1 is more portable but I am wondering specifically about the receiver 
performance between the two. Also in regards to the K2. I know the K2 is 
a better reciever but I'm coming from one disappointment. I purchased 
another rig that I was going to use as my backpacking rig but it's 
reciever is not that great and nothing I do makes it better. I may want 
the world, but I would like to have a decent receiver. On top of that, 
as long as it transmits and is decent on batteries, the other 
functionality is marginal on my list of priorities.

[Elecraft] K1 or KX1 ??? That is the question.

2005-09-26 Thread Kevin Rock


Whether 'tis nobler to bear the slings and arrows of outrageous 
propagation or with a kit end them?


You guys and all this talk of kit building is making my nose twitch and my 
fingers itchy.  The soldering station is ready, pad wet, and rosined 
solder to the fore.  Now which shall it be?  My stalwart K2/100 #2511 
works quite well each Sunday afternoon and each weekday morning for its 
various nets and skeds.  But I want another rig to carry with me on trips 
and campouts.  I am torn between the masters (read Wayne and Eric here) 
other two rigs.


The KX1 has great reports: heck I give them all the time during ECN.  They 
work quite well in the hands of the best (Ray, K2HYD and Rick, KL7CW 
please take a bow).  Seems like they can beat their way through pileups to 
get my attention ;)  I never truly believe them when they tell me 3 watts 
but it must be true.  I've even worked Wayne from the sandy shores of Lake 
Michigan while he was contesting with his KX1.  However, the K1 was shown 
to me by Karl, N7NLU during a contest where it worked admirably from our 
local park.  It had some very nice features which pull my attention away 
from the KX1.  More bands are covered but it does not cover so broad a 
frequency range as the KX1 in each of them.  I also am not sure how well 
it may work during cross mode contacts.  But, the countersunk screws sure 
are enticing.  Once again in the hands of a master (read Ric, VE3XL with 
his late, lamented K1) it shines.


Some of you have solved this dilemma by building one of each.  I am fairly 
sure Wayne and Eric do not mind this solution.  Then there is the input of 
the holder of the purse strings.  How can one sneak another kit into the 
house without her approval?  What should I say when asked?  I know she'd 
send a nastygram to Elecraft in a minute if my heart is not pure and my 
reasoning sound.  What to do?  What to do?

Re: [Elecraft] K1 or KX1? Looking mainly at receiver

2005-08-01 Thread David F. Reed

Jeremy,

I own a K2 and a KX1, and have some opinions; but I think there is no 
hard and fast answer.


The K2 is superb; its receiver is about as good as my Icom IC-7800; no 
joke.  Yes there are a few conditions in which I prefer the Icom, but to 
me, that is an amazing feat given the price difference.  My only 
suggestion that might improve the K2 receiver performance factor for me 
would be improving the noise blanker & noise reduction DSP somewhat.


When you say "as long as it can transmit" do you mean CW only?  I assume 
so from your consideration of a KX1.


I have not had my KX1 long enough or used it enough under varying 
circumstance, but it is more portable and has some nifty features, and 
is easier on the battery, and I do really like it.


Perhaps you could share with us what rig you were disappointed by, and 
in what ways; since all solutions are compromises to some degree, it may 
help us better advise you.

I don't want to since all the other people I've talked to seem to have a 
fine rig. I don't want to degrade it for something that may have been my 
mistake. I have run into a few other people that are having my same 
problem though. I really don't think it was my building of the rig that 
caused the problem because I am an experienced builder that was very 
carefull. I have built many kits (OHR-100A, 38 Special, Rock Mite, ZM-2, 
Ten Tec 30m, K2 (#600), KD1JV's Digial SWR/Power meter, etc...) all 
those are great rigs and work as expected.


The rig I am comparing to is an IC-703 which has a pretty good reciever 
in it and I don't expect any of the rigs to compare to it, but I do 
expect them to at least hear that signals are present when on my 703 
they are copyable w/little difficulty. Is my expectation too high? I no 
longer have my K2, I was dumb and sold it to get into satellite ops. 
Today I rarely do sats but have remained constant with QRP.

The KX1 is hard to beat for your need.  The Rx is about as good as 
you're going to find in that size radio, it is light, and with the 
paddle and ATU, is really trail-ready.  I've been powering mine with an 
850 maH Li-polymer battery I got at the local RC Model shop that weighs 
an ounce to two.  12V for about 4W, and it easily lasts thru a Spartan 
Sprint.  Actually, it lasted through a dozen or so QSO's while on a 
15-day cruise through the Panama Canal this spring.  My only complaint 
when using the KX1 in the S. Sprint is that at 1.5 hours, I kind of run 
out of people to work because everyone has gone to 80m.

Jeremy wrote:

>I know the KX1 is more portable but I am wondering specifically
>about the receiver performance between the two.

If properly built, the K1 has a somewhat better receiver than the KX1 in most 
areas.  The advantages of the K1 receiver over that of the KX1 are:
(1) Bands of operation.  The K1 offers 15m in addition to the bands on the KX1. 
 This is important, even in waning solar cycles, because when it's open 15m is 
one of the finest of QRP bands.  An additional two-band board will let you add 
80m and 17m.  The clocking limitations of the direct digital synthesis (DDS) 
chip in the KX1 prevent operation on bands much above 20m.
(2) Receiver I.F. filtering.  The K1 has a four-pole crystal filter.  The KX1 
has a three-pole filter.
(3) More natural tuning.  The K1 has an LC VFO which tunes as fast or as slow 
as you turn the dial.  The KX1 has step-wise DDS tuning, with manually 
selectable tuning steps.  Not as natural, IMHO.
(4) Cleaner RF response since the K1 has an LC VFO for its local oscillator 
(LO).  The KX1 uses a DDS (without PLL) for the LO.  All DDS generation schemes 
(except DDS-locked PLL systems) have spurious outputs which adversely affect 
recever performance.
(5) Good internal speaker on the K1.  No speaker on the KX1.  I don't like to 
be tied to the radio with a headset if I'm just casually listening to a QSO.
(6) Front mounted controls.  I hate top mounted controls, except as a 
concession to simplifying the design and reducing the cost of a rig.   I do not 
consider them "trail friendly."

In the transmitter arena, the K1 offers higher power output if needed, lower 
spurious output (that DDS thing again), and most importantly the K1 ATU (KAT1) 
is a considerably wider range tuner compared to that of the KX1.

However, in real life, whether you will notice some of these K1 advantages is 
open to question.  The KX1 is indeed a fine little rig.  Some of the KX1 
advantges over the K1 are:
(1)  DDS gives crystal-like temperature stability, far better than the K1 
(though the K1 is much better in this area than I would have expected for its 
LC VFO).
(2)  The KX1 can tune a wide segment of the HF spectrum and can thus serve as a 
small shortwave receiver for other things besides ham radio (SW broadcast 
stations and utility stations, etc.).   The K1 covers only only the CW segments 
of its ham bands.
(3)  The KX1 receiver can function in either LSB or USB mode.  You can tune the 
phone portion of 40m and 20m with it.  The K1 receiver can only function in LSB 
mode.
(4)  A host of nice bells and whistles, like lighted frequency display, and 
audio annunciation (can be operated blind).  The K1 has neither.
(5)  Very small bulk and light weight, even compared to the K1 (unless you 
start making extras like an external speaker for your KX1).

I chose the K1 five years ago, three years before the KX1 became available.  I 
would still chose it today, but I can understand the popularity of the KX1 
especially if 15m isn't required.  You can hardly go wrong either way.

RE: [Elecraft] K1 or KX1? Looking mainly at receiver

2005-08-01 Thread EricJ
I got a K1 instead of a KX1 mainly because most of my field trips are day
packing or car camping, not backpacking. The K1 is an exceptional performer,
but I if my interests were in a backpacking rig, I would have gone with the
KX1. 

I haven't been backpacking in a long time, but, from experience, at the end
of the day, radio wasn't usually uppermost on my mind. Between all the
"chores" necessary when making camp and spending some time with hiking
friends or star gazing, you may find you will do a lot less radio than you
had planned to do. The K1 with accessories is a lot of stuff to drag around
if you don't use it much. The KX1 will be less of a burden.

I think a realistic assessment of your needs will point to the right choice
for you. The K1 and KX1 overlap in a lot of areas, but they really do serve
different purposes.

It was reported:

> ... the KX1 wins handsdown for backpacking...

Strange!  Before the KX1 came out, the K1 was generally acknowledged as the
best multi-band backpacking rig available.  It is no less suitable for that
task today.

If one is happy with the limited number of bands covered by the KX1, and
recognizes that there is absolutely **no** physical way that KX1 receiver RF
performance can match that of a properly constructed  K1 in any area other
than VFO stability, and that the ATU in the KX1 can't come close to the
matching range of the K1's KAT1, then the KX1 is a great choice.  On the
other hand, if RF performance *on the ham CW bands* is important, the K1
stands as the best of the two.

When I'm out in the boonies, I want the best possible RF performance on the
ham CW bands that I can get in a small package.  The K1 hasn't been shaken
from that position.

I don't care that I can't use it for shortwave broadcasts or to copy the ham
phone bands.  I've got a Sony portable that'll do that quite adequately,
with essential AM/FM coverage to boot.

So whether the KX1 "wins handsdown" depends on the criteria applied.  It
doesn't "win" for me, handsdown or otherwise.

There's nothing strange about a product evolving to improve in some ways while 
the old one remains suitable to task.  Those two facts can co-exist quite 
happily.  Understanding your needs and the tradeoffs between the rigs is the 
key.

When you go out and spend $200.00 on a 1 person tent that is 1lb lighter 
than your previous tent, and another $180 on a sleeping bag that is 
1/2lb lighter, and continue to do so so your pack drops from 35lbs to 
30lbs the KX1 is now a much better backpacking rig. Not only is the 
radio a little more than 1/2lb lighter, the batteries to power it for 
the same timeframe are lighter as well. Now, if your saying the KX1 will 
not work, then it's just dead weight when packed and that would be a 
different story.

For real backpacking it seems worth the comprimise.

Re: [Elecraft] K1 or KX1 ??? That is the question.

2005-09-26 Thread David Toepfer
Based on replies I got recently, and what I have heard for a while, it seems
pretty easy.

If you want something really easy to grab and go, especially light camping and
pedestrian mobile, go KX1.

If you want something for easy mobile, camping with some extra weight and room,
and for hotel duty, go K1.

The K1 seems to get the nod over even the K2 with many for casual ragchewing. 
Many describe it as having an undescribable quality that makes it easier to
listen to.

Just what I have heard.  I already own a KX1, which was fun to build and even
enjoyed passing on feedback on the manual and build process back to Wayne and
Eric.

I have hemmed and hawed recently over which rig to get next, including the
impressive new NorCal NC2030, but I hope to be ordering my K1 quite soon.

Hope this helps.

David, K2TUE
