And, I guess the next question will be, will there

1. It will have a separate power supply.  I'd estimate the weight for a good 
3kw switcher in the 10-12 lb area.
2. The tuner will be another separate unit.  No idea on a weight for this one.

Re: [Elecraft] OT: Feedline Question

Hey, and it looks like you are really in 7-land, Wes!

OTOH, I'm the "real W7OX", live in a suburb of Los 
Angeles and have not lived in 7-land (OR/WA) since 
1960; farthest North was Palo Alto when I was at 
Stanford 1963-65.  But 20 years ago we considered 
retiring to Portland very seriously, so I used the 
Gates to get back my original call -- W7UOX -- and 
then shorten it to W7OX.


I like having the call for old times sake. But I 
do wish the prefixes had call area geographic 
meaning as they did in olden days.

Quite a few years ago, N6WS did some excellent

line he built himself. Putting some numbers to 
it, Wes's measurements showed loss at 50 MHz 
increased from about 0.4 dB/100 ft to more 
almost 6 dB/100 ft when it was wet. The open 
wire line showed no increased loss when wet.

One issue with mobile QRO is the antenna. While a mobile whip/loading coil

One fairly common solution decades ago was to mount a copper toilet tank float 
on the end of the antenna. Of course the wind resistance then required guying 
the whip. Since it was typically on the rear of the car, a nylon cord from the 
mid-point to somewhere forward on the roof was common.

Another approach - back when car bodies were steel - was to extend the whip to 
it could be bent over and tied to the front bumper, turning the car body and 
whip into a small loop antenna.

Today, it might be hard to establish the necessary distance from the antenna 
while sitting in the car to meet modern RF exposure limits, especially on 20 
meters and up.

I never went QRO in my car, but had buddies who tinkered with it way back when vacuum tubes were 
"king". Back then I lived in the land of the "California Kilowatt" (Southern 
Calif.). They mounted outboard generators on their car engines to handle the power demand. Adding 
filaments, etc., a kW mobile station might require 1.5 or 2 kW of d.c. power to run it. Got a 
chuckle out of them when they'd key the mic to transmit while sitting at a stop light with the 
engine at idle, and the sudden added power demand caused the engine to stall.

Best advice so far, Lynn. To the OP: Get something, then GET ON THE AIR.
Nobody learns from reading specs and opinions. It isn't the way to find
your first rig, and probably wasn't the way you picked your first
girlfriend. Play the field. The learning starts when you take the
plunge. You'll know what you want out of the next rig.

Good used rigs aren't expensive, and if you buy wisely, you can get most

Hi All,

I'd be inclined to think the KX2 measurements

which was designed to be a close competitor to 
K3 performance (a K3 in a smaller package), the 
KX2 is more a pared down version of the KX3, and 
some of that paring down probably affected the 
specs somewhat.  I don't think this paring down 
process was allowed to noticeably degrade 
performance.  I can tell you , though, that it 
is very hard to notice any significant 
difference.  It has somewhat different 
architecture, but is an excellent performer.  
This sort of proves to me that being "top tier" 
on Sherwood's stats is nice to talk about, but 
not necessarily critical.  That's why so many 
owners of older rigs have a hard time "hearing" 
the benefit of what newer designs purport to offer.


Wayne says he guesses the KX2 might rank 
somewhere in the top 20. If so, that's pretty 
darned good!!!  I'd also be inclined to bet that 
Wayne already knows about where it will fall!  I 
just hope that, when the numbers do come out, we 
don't go through an ad nauseam exchange about 
some spec being a big problem or a serious 
disappointment.  A lot of these differences are 
only determinable in a lab!  On the other hand, 
if something does seem to be a real problem, I'd 
also bet it can be fixed!

Re: [Elecraft] Augment KX3 or buy K3?

[Phil Wheeler]

Gareth,

I agree with both Don and George regarding the K3s 
advantages. I also find it's performance pluses to 
be significant in crowded band conditions.  I'll 
add two more considerations.


Ergonomics: My K3 is just easier to use in the 
shack than my KX3. More dials, bigger buttons, 
easier to use in its position, etc.  The tilted 
KX3 is just not so user friendly.


Shack layout: Having a separate amplifier would 
mean more cables to fuss with.


If I were in your position, I'd think about buying 
the K3s, the P3 (if a panadapter is important to 
you) and then -- if you use the KX3 only for 
things such as SOTA -- selling it and replacing it 
with the smaller KX2. Now that I have a KX2 I 
seldom use my KX3 (even though I have the PX3 as 
well). The "QRP-ness" of the KX2 makes it a fun 
rig and its performance seems right up there with 
the KX3. Only disadvantage -- unimportant to me -- 
is fewer bands. And I far prefer the KXPD2 to the 
KXPD3 -- again, likely a personal preference.


Not all will agree, but that's what I'd do in your 
situation (sans financial considerations, of course!).

I did not know the PX3 has the same size screen as the P3.  The P3 does have 
additional optional features not available with the PX3.  These include the TX

If you are into contesting or DXing or otherwise dealing with pileups,

If you operating is a bit more casual than that, then add the KXPA100

I am in the fortunate position of having some money to spend upgrading my

My options at present seem to be:
1) Reserve the KX3 for SOTA and buy a K3S, (but nothing more I only have
enough for a K3S)
2) Add a KXPA100 with ATU (and maybe a PX3) instead.

Those MFJ single-band whips are not particularly

You shouldn't judge the KX2 based on that test.

Same goes for other Elecraft gear like the 
KAT500 and KPA500. For the XG3  there was a 
recent firmware update to it.  As of now I see 
no need for it but knowing it exists I would do 
it next time I use the XG3.


Hopefully the powers in charge can consider a 
more complete mod/update listing.   Maybe a 
criterion to make the list could be, "What would 
the factory do?" By that I mean which are 
important enough for them to do when a piece of 
equipment is returned for repair and updates.

Re: [Elecraft] K2 / DSP

[Phil Wheeler]

Years ago I replaced the KAF2 with a KDSP2 and far 
preferred the latter.  But it is fussy to adjust 
and many seem to prefer the KAF2.

Re: [Elecraft] KDSP2 discontinued??

[Phil Wheeler]

Such things are probably doable, Kevin. But the 
market size issue is likely a major factor 
mitigating against such a development by Elecraft.


If I were to build a second K2 after all these 
years, I'd sure want the KDSP2 in it; but that's 
not something I'm likely to do. My (partly) 17 
year old K2 #380 is still working quite nicely and 
fully upgraded with all Elecraft updates -- and 
some 3rd party ones, too :-)

When I saw the announcement I wondered about the

based on an FPGA such as a Spartan 6 (for example).


I'm not sure how it would affect the price but 
it would make the board a little less prone to 
parts decaying in to the state of unobtanium.

Re: [Elecraft] KX3 utility on RPi

Jim,

The Elecraft site

*Minimum Operating System Requirements for 
Elecraft Utilities:*


*Microsoft Windows*: XP Service Pack 3 or later,

*Apple Mac:* OS X 10.6 (Snow Leopard) or later

*X86-based Linux:* GTK+ 2.8 or later, glibc-2.4,

Re: [Elecraft] wanted k2/ is the kx3 is better in what way ?

[Phil Wheeler]

Elan,

In my opinion, the KX3 is the better QRP 
transceiver of the two. The K2 is a fine radio, 
but the best part of it was building it myself.


The KX3 has more advanced technology (a 10+ year 
newer design) and will now deliver 15 Watts on 
transmit. It also covers 6 meters and has all-band 
receive (K2 is ham band only). It also supports 
the PX3 panadapter.


Because my K2 has the KPA100/KAT100 combo, it's 
also my second higher power radio now (with the K3 
in my primary operating location).


And then there is the KX2 .. my most-used QRP 
radio now :-)

Generally it's supposed to be "K3S" (capital). Please use that in email.

However, on the radio itself, and in the owner's manual (etc.) we use a 
slightly \
smaller capital "S". To be specific, about 85% of a full-height capital. This

I'm looking forward to seeing a blog post with the official "S" scaling :)

Re: [Elecraft] Camping radio ops: then and now

[Phil Wheeler]

I know where you're coming from, Mike. Like you I 
built my own K2 from the ground up starting in 
1999 and "completing" it in 2003 with the KDSP2 
(and some other adds updates in 2014); I still use 
the K2 regularly even with a K3/P3/KPA500 etc. My 
favorite time in the hobby was building QRP rigs 
-- many designed by Wayne -- in the 90s. And, 
Mike, I do note with appreciation your many 
contributions to the K2 odyssey!


Alas, times have changes and short of building 
another K2 that sort of pleasure is no longer 
available to me: SMT and have not become friends.


Sure I'd like to have a KX2 schematic -- and 
haven't concluded Elecraft won't provide one in 
time. But I won't deny myself the pleasure of 
using it -- and pleasure it does provide -- for 
lack of a schematic.

Mine works just fine, without schematics.

It's just a matter of principal, Phil.  I've never in almost 49 years a ham 
purchased HF gear that did not, at minimum, include the schematics.  I'm a 
retired electrical engineer for whom knowing a little about what's inside the 
box is actually **much more important** than knowing how to operate the box.

I accept that firmware will always be shrouded and proprietary.  For the 
hardware, if the complete (though not wholly current) KX3 system schematics can 
released, it is hard to understand why the same hasn't happened for the simpler 
KX2 system.

Mine is unpopular philosophy today, when ham gear is becoming more and more 
like smartphones whose internal workings are shielded from the view of the 
vulgar mob.  (For my phones, I get as much info as I can from the FCC OET 
Device Listings ... even for Bluetooth headsets!)

I just did not expect Elecraft to adopt that attitude.  :-)

When I got out of the Navy 37 years ago, I immediately returned to Arkansas

My now-defunct K1 had been my principal camp rig since 2001.  I'd like to

My first attempt to operate from a campsite was in 1972, when I was 14. My dad 
chuckled as I hefted my box of gear into the camper. At the time I had no 
battery powered radios. The receiver was a Heathkit HR-10B. The transmitter was 
a 3-tube, 10-watt, WW2 CW monstrosity I borrowed from someone in the El Cajon 
ARC. I also didn't have an antenna tuner, so I brought a full-size 40-m dipole 
with #18 wire and 100' of RG58. Keyer was a Heath HD-10.

Our campsite in Utah didn't have an electrical outlet. Fortunately I had a very 
long extension cord that I routed through the window of the  men's room, two 
campsites down. I had to apologize to hostile strangers as I wove the cord 
through bushes and around cars.

Getting the heavy dipole up into the ponderosas required rope, rocks, and a few 
swear words I hadn't used in front of my parents prior to that time.

Finally, I was on the air. Unfortunately the band wasn't particularly open that 
day, and I think I ended up making three contacts. Still, I got The Bug.

These days, I use a KX2, two lengths of #26 wire, an earbud/mic, and a KXPD2 
paddle. Total station weight: 2 lbs, counting the CS40 bag. Setup time: 2 or 3 
minutes, depending on how many times it takes to hit just the right branch with 
a 1 ounce stainless steel weight. Or 1 minute if I'm using a whip.

It's been a wild journey that I suppose could be graphed in terms of miles per 
watt per pound over 40 years.

I bet there a few other variations on this theme

Re: [Elecraft] K2 Utility

[Phil Wheeler]

John,

If you have a newly built K2 all firmware should 
be the latest.


If you have an older one, purchased used, you may 
or may not need to upgrade the firmware by 
obtaining the ICs from Elecraft. To make that 
determination you must disassemble the K2 so you 
can see the firmware ICs and note the version 
written on them. Then look at the Elecraft site as 
Don says below and see if your chips are the 
latest -- and what any needed updates will do for you.


The K2 was designed in the late 1990s. It and 
other early Elecraft transceivers (e.g. K1, KX1) 
did not have the capability to update firmware via 
downloads but required replacing the firmware 
integrated circuits.

I use an Apple camera adapter (lightning to usb) with a Griffin iMic

Re: [Elecraft] Soon to be an Elecraft(er)!

[Phil Wheeler]

Re "Is it safe to assume I won't be loosing any 
performance by making this chance and even gain 
some?": If you mean the KX2 or KX3 vs. the FT-817 
you should have better HF performance by far. And 
you can opt for an internal ATU in either rig, a 
huge plus in my mind, Brian.


What you lose is the 144/470 all-mode capability 
of the FT-817 (which is why I kept mine as long as 
I did). You can add 2m to the KX3, but I've not 
done that.


While the KX3 has features not available in the 
KX2 (more bands, a roofing filter, feasibility of 
adding the PX3 panadapter, a bit more power), I've 
found the KX2 to be an equally good QRP rig.

Hello All,

Not an Elecraft owner yet but making plans to be one soon. I’m just starting 
the research.

A close friend is all Elecraft and I'm impressed. Even meeting the company 
owners and designers at Dayton has me sold on them.

My QRP rig today is an FT817 which I love (I have been known to sleep with it 
under my pillow lol) and have had a few memorable QRP mini-expiditions on 
vacation trips to Central America, France and around the province.

Currently my primary base rig is a Kenwood TS590 no complaints about it so far. 
I have been approached by prospective buyers with reasonable offers to sell 
both these rigs. So I am giving serious thought to using this opportunity to 
get a KX3 and the KXPA100 100W amplifier/tuner combo to replace my TS590 as a 
base radio. I would then use the KX3 on its own instead of the FT817 for my QRP 
trips.

I am playing now with the HF digital modes such as FreeDV, PSK31, JT65, WSPR so 
hopefully CAT and audio interfacing to a computer is easy. Today I use a 
SignaLink USB.

I like the idea of getting to know one radio really well (the kx3) by using it 
as my primary rig on the road AND at home (maybe even in the mobile at some 
point). I would then save my pennies for the PX3 and even a KX2 for lighter 
travels at some point.

Is it safe to assume i won't be loosing any performance by making this chance 
and even gain some?

Hopefully no trolls on this group.

Thanks,

Re: [Elecraft] K3S - Build or Buy

[Phil Wheeler]

Having built the K2 and all accessories, I ordered 
my K3/P3/KPA500/KAT500 assembled -- mainly due to 
the size and weight of some (particularly with the 
KPA500). The K2 was all the building experience 
(from 1999-2003 as accessories were developed) I 
really needed -- along with other, smaller kits.


I did assemble the KX3 and PX3. And in the case of 
the KX3 I rather regretted that choice: One small 
mechanical part, a standoff, was not usable and I 
had to wait five days for a replacement. Of 
course, in the long run it hardly matters.  But I 
do find the "melt solder" kits more fun to build 
and get working, and miss the days when so many 
thru-hole part kits were available. The K2 is the 
last really challenging one, IMO.

Subject: [Elecraft] KX2 battery in PX3
   With all the discussion on KX2 IQ output going on, I don't want to muddle
things up even further, but as Mark KE6BB was reminding me earlier, there
is a nice way you can power the PX3 using a standard KX2 battery that I
demonstrated a couple of weeks back:


https://www.dropbox.com/s/39wjrgp1bad3xg5/KX2%20Battery%20in%20PX3.jpg.jpg?dl=0

I did this some time ago and it works great - it looks like Elecraft
made provisions for such a battery in the design of the PX3 PCB. You need
to open the PX3 to recharge the battery, but it actually lasts for quite a
while, I haven't made precise measurements yet though.

my 2 cents,

Ed, W6ELA

Re: [Elecraft] KDSP2

[Phil Wheeler]

Au Contraire in my case, Johnny.  I've found the 
KDSP2 to be very effective and still use my K2/100 
in my secondary operating location as my QRO rig.


The issue with the KDSP2 is getting the settings 
right. That was tricky and probably took me a year 
or two of experimentation. But now it works very 
well for me and I find the NR very effective.

KAF2 in the used market is really cheap.  Adding the KAF2 will not cost much

In my shack I have a large LaCrosse clock, updated 
nightly by WWVH or some such: $35 or so on line. 
On my wrist I often wear a Casio wristwatch with

I prefer Elecraft to focus on what they do best,

As I said earlier, in a letter to Dean Straw

assumed Qc = 1000 and Ql = 300 (generous). I

With lower Q components, Qc = 500, Ql =200, the

The G4RV is definitely a compromise antenna.  
However its advantage is that is has low-enough 
SWR to be easily matched by most tuners on a 
number of bands.

It's true that tuner losses are the 
manufacturers' dirty little secret. Loss is 
rarely specified, partly because it can be 
pretty bad, and partly because it is hard to 
measure, but also because it is not constant - 
it depends on the particular impedance being 
matched.


One exception is the old Drake tuners.  Their 
Pi-L topology makes the loss almost independent 
of the load impedance.  If you can get it to 
match, you know that almost all the power is 
going into the feed line. For example, the 
MN-2700 that I designed when I was at Drake was 
specified at 0.5 dB maximum insertion loss and 
I did a lot of testing and tweaking to achieve 
that on all bands.

Re: [Elecraft] KXPD3 vs. KXPD2

Don,

The Adventure can be mounted to the rig (Begali 
has an adapter), and some have even added a plug 
like the one on the KXPD2/3. I use the Adventure 
on my KX3.


But after receiving my KXPD2 I find it to be a 
fine key, not as adjustable as the Adventure but 
great for my purposes. I tried another owners 
KXPD3 and did not particularly like its feel -- 
but I'm very pleased with my KXPD2. If not for the 
Adventure I'd buy a second KXPD2 for my KX3! In 
fact I may do that and sell the Adventure.

KXPD3 vs. KXPD2?
Paddle preference is of course a personal choice that will vary from individual 
to individual.  I own a KX2, KX3, and a few K3s  …. And I also have the 
respective KXPD paddles.  I consider the K3 to be a much better transceiver 
choice for use in the shack and I use a Begali Sculpture paddle with two of 
them in SO2R configuration…. It’s a wonderful paddle.

I bought the KXes for portable operation only and, to me, that is where they 
really shine  … they’re each perfect for light travel, easy setup and hassle 
free operation using a minimum of extra gear and cables.   To me, the KXPD 
paddles are the clear no-brainer choice for use with them …. I didn’t even 
consider the Begali Expedition when it was offered  … partly because of the 
necessary extra cable … but also because at the time I was perfectly happy with 
the KXPD3 and KX3.  I’m talking about portable operation here … sitting on a 
park bench, a car seat, a folding chair or a rock under a tree …. Where comfort 
is nice to have but is definitely secondary …. So the finite details of the 
paddle are not important.

When the KX2 came along I used the KXPD3 at first and was happy with it … but 
when the KXPD2 arrived later it immediately became my paddle of choice for both 
KX2 and KX3.  It’s shorter, a bit lighter and easy to adjust … but the biggest 
difference to me is that the paddles have beveled edges and are smoother to the 
touch when compared to the rather sharply formed KXPD3 paddles.   I will take 
either one … but I now prefer the KXPD2 for both radios…. And my favorite 
paddle is still the Begali Sculpture … but I’m leaving it in the shack with the 
K3s  not the KXes.

Just one man’s opinion..

Subject: [Elecraft] KX Paddles

Hi guys
I’m planning on buying a KX3 in the near future.  Some time ago someone on the  
reflector said they thought the new KXPD2 paddles were better than the KXpd3 
(less noisy I think he said.)  Any pf you who have KX3’s and now also KX2 can 
now make that comparison.  So what’s the verdict?   Should I get the KXPD2 
paddles with my KX3?  I’d like to hear some opiinions pro or con. I am mostly a 
cw op.

  Thanks

Sid Frissell, NZ7M

everyone that there is.  If everyone used

Re: [Elecraft] Crowdfunding a 1500 watt amp - SURVEY?

My whole Ham life I've been told to put the

If you are a skilled operator then you'll make 
the contact if band

conditions permit.
Doing the math I really don't see why anyone 
"needs" an amp past

500-600watts. Maybe on 60/160?
If a QRP /Low power station can make the 
contact but you can't then maybe
you need to ask for help getting your station 
optimized a bit better.

Just my view.
I used to run an SB220 and loved it when I made 
the contact. I later came to
resent Ops I heard running power just to get 
over the pileup.
I sold the Amp and don't regret it for a 
minute. If I were to get another
amp the math shows 500w to be the sweet spot, 
however, I have so much
opportunity to improve feedlines and antenna it 
doesn't makes sense to run

power at this time.

All other products were designed by engineers

Yes, from 2006. Two versions of the amp were on display at Dayton, the
KPA800 and KPA1500. Both were working prototypes and both were putting
out power, the KPA1500 at 1800+ watts continuously into a dummy load, if
I recall properly. Both were things of beauty and planted the Elecraft
seed in my brain that eventually resulted in my having a complete
K-line, minus the KAT500.

K3 or K3s?

I'm a new owner and all worked fine.  After an absence of a few days I came
back to no power out, or , at least, very little.

Rig is the 100W version with ATU working into a dummy load.  In CW mode
adjusting the power level to 70W produces only a one segment power out.
Running the ATU produces a 5W indication, the usual searching rumbling, but
no resultant SWR. The Test mode is NOT in operation.

I have restored to the last working config via K3 Utility, but suspect I
must have "hit" something to limit the power.  The FP and AMP temps were too
high (35C) when the problem was noticed. I set them down to a more
reasonable 23C without effect. Input voltage is 12.8V.

Probably something trivial, but suggestions would be appreciated.

Re: [Elecraft] Help sell me on the K3S

[Phil Wheeler]

Reuben,

Since you say you have the K2, I'd get your 
license before adding any new rig and use the K2 
to start out. Even without the amp you can run 10 
Watts or so and get your feet wet.


After you've operated for a while you'll have a 
better idea of what you want.


OTOH, if you plan to operate SSB 100% of the time 
(I tend to forget CW is no longer required!), then 
perhaps you should start with a 100 W rig; 10 
Watts on SSB might be a bit discouraging on 20 
meters particularly with our current band conditions.


If you are willing to start with 10 Watts on SSB, 
then you might be well advised to add the SSB 
module to your K2 (assuming it has none now) and 
get your feet wet with the rig you already own vs. 
buying the 10W K3s immediately.


I consider the K3s/100 to be your best choice if 
money is no issue. Great rig and great support, 
both from Elecraft and the user base here. But you 
should start with it minimally configured (e.g., 
don't add a bunch of roofing filters -- but do add 
the ATU because you have a G5RV and will need a 
good tuner).


Below you say "In the past week I found out about 
the Icom 7300, which for all intents and purposes 
is one heck of a nifty radio too.". While the 
IC-7300 has some shortcomings it's a good radio 
that you could probably be satisfied with for 
years. So that might be a very good option for you 
as you first get into ham radio.


Whatever you decide, give highest priority to 
getting your license, Reuben. Then you can start 
having fun :-)

Hey everyone, happy early 4th to you and yours!

I'm looking for a bit on input here.  I've had my K2 now for quite some
time now; built it myself and love it still to this day.  But, because
every guy and gal needs a new radio every now and then, I've got that itch.

I've had my eye on a K3 probably since I first saw the advertisement in QST
some years back.  I'm not a contester.. heck, I *still* don't have my
ticket, so my main use is SWL and running up and down the bands to listen
in on some of the nets.  My antenna is just a half size G5RV slung along
the apex of my roof but I've wanted to get my hands on the K3... that
is until now.

In the past week I found out about the Icom 7300, which for all intents and
purposes is one heck of a nifty radio too.  And at $500 less than what the
10W K3S.  That's a nice chunk of cheddar in these days and times, doubly so
as Popp #2 will be arriving here come September (on my birthday no less,
hah).  The downsides are (at least to me) is that there's little in the way
for adding on new features to the set short of via software updates.
There's no second antenna option, etc, etc.

Granted, I'm not looking at getting either one anytime in the immediate
future.  Or, if I miraculously get one somehow, something is seriously
wrong, and someone has replaced my XYL with the Stepford model... come
please make sure I'm okay, lol.  But in all seriousness, help me decide
here.  Which is the better bang for the buck in the long run?  I'm willing
to bet that this will be the last rig I get for quite some time yet, so I
had best make it count.

Thanks in advance to all and 73

Re: [Elecraft] O.T. Tuning a Counterpoise

[Phil Wheeler]

Thanks, Ron. You just reminded me that I have an 
MFJ-934 (ATU with artificial ground) stashed 
somewhere.


No real need for it just now, but who knows?  Now 
I just need to find it!

One approach to reduce "RF in the shack" using an end-fed wire is to
resonate the "counterpoise" for the band you are using. MFJ made just such a
"tuner" (model 931 IIRC) but any tunable L-network will work. The idea is to
adjust the "tuner" for maximum current flowing into the counterpoise
(meaning the counterpoise is offering the lowest possible impedance to the
equipment it is connected to.) I have successfully used that in a 2nd story
apartment feeding an end-fed wire running outside. I know one Ham who bought
the MFJ box and found it worked FB.

For a homebrew "counterpoise tuner" you'll need an RF ammeter but a good
cheap one is an incandescent flashlight bulb in series  where the
counterpoise connects to the rig chassis. Tune for the counterpoise for
maximum brightness with the rig running at the lowest power that will light
the bulb, then short-circuit the bulb for higher power. Of course, the
adjustments will interact with the tuner settings for the end-fed wire. But
the "tuning" of the counterpoise is usually broad enough (low-Q) that noting
the settings for each band you can return to them without doing the whole
retuning thing again. (The MFJ box my buddy bought has an ammeter built in.)


My "counterpoise" was a thin white wire run around the baseboard of the
shack and down the hall - about 30 feet total. White wire + apartment white
wall = invisible counterpoise. Worked FB 40 through 10 meters.

While that will reduce the RF voltage on the rig itself, you will be sitting
in a high-level RF field from the end fed wire, which limits your maximum
power to meet radiation exposure limits, depending upon how far from you the
antenna is located and the band you are using.

Re: [Elecraft] New KXPD2 paddle for KX2

Ken,

Please clarify what is meant by "I had problems

assertive!": What problems, and assertive in what 
respect?


Really a bit academic: I never owned the KXPD3 and 
have ordered the KXPD2 for its shorter arm and 
less tendency to move the KX2 around, as you observed.


Like many here, I still wait for my KXPD2 to ship.

Re: [Elecraft] Elecraft] KX2

[Phil Wheeler]

There is a terminology issue, Charlie. The "EFHW" 
I use is this one: 
http://www.earchi.org/92011endfedfiles/Endfed6_40.pdf 
and is fed via a 9:1 UN-UN. Uses the coax shield 
as a counterpoise and seems to work well over the 
bands of interest -- depending on the length of 
wire used. An ATU is generally essential, and the 
one in the KX2 is very capable.


Phil W7OX

On 7/15/16 5:34 AM, Charlie T, K3ICH wrote:

One other question I have concerns the length of these "EFHW" antennas that
many are using.
That is, are they REALLY End Fed Half-Waves?  In other words, are they cut
to be an electrical half wave-length or, are they simply a convenient
length of wire, that is fed at one end?
There could be a drastic difference in the feed point impedance depending
on this parameter.

Also, what's wrong with making a true "Zepp" antenna on the higher bands by
adding the required length of twin lead for the ¼λ matching section?  On
20 M and up, this would result in a fairly easy length of wire to deal with.

Anybody tried that approach? I know the "J-Poles" are popular on VHF, but
how about a 20 meter wire J-Pole?

Main fun of  the K1 and KX1 is building them :-)

The K1 is still sold...see 
http://www.elecraft.com/k1_page.htm . The K1 
remains an excellent small CW-only transceiver. 
However, the four-band KFL1-4 filter board has 
been unavailable for a couple of years.


The original posting in this thread contrasted 
the KX1 vs. KX2 or KX3. If RF performance 
mattered, where the K1 is clearly superior to 
the KX1, the 16-year-old K1 deserves honorable 
mention among small QRP transceivers:
(1) The K1 uses an LC VFO that is cleaner than 
the DDS 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.
(2) The K1 can be placed on any of the HF bands, 
although Elecraft sells parts for 80m through 
15m only. The KX1 DDS chip is clocked at its 
maximum rate of 50 MHz, which limits KX1 highest 
frequency coverage to around those of 20m band.
(3) The K1 IF uses a four-pole crystal 
filter...the KX1 IF uses three-pole. This makes 
a very noticeable difference in selectivity.
(4) The KAT1 produces a larger number of 
configurations (1020) of impedance than the 
KXAT1 (124). (It's of note that the KXAT2 
produces 32764 different network configurations, 
264 *times* the number of the KXAT1. The KXAT3 
produces 131068 configurations, 1057 times the 
KXAT1.)
(5) Many find continuous K1 LC VFO tuning more 
natural than step-wise KX1 DDS tuning.
(6) The K1 has a noise blanker option...the KX1 
does not.
(7) The K1 transmitter can produce up to seven 
watts of output power. The KX1 is about half 
that...at best.

(8) The K1 case has a speaker...the KX1 does not.

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


With respect to the KX1 vs. KX2 or KX3, the gulf 
in capability and performance is so great as to 
render the question absurd. The only advantage 
to the KX1 over the KX2 is that Elecraft 
provides a schematic for the KX1...something 
that very noticeably withheld for the KX2 and 
its accessories. That implies the customer is an 
"appliance operator".

Re: [Elecraft] KX2 - KX3

[Phil Wheeler]

I know what you mean, Bill. I become attached more 
to a rig I've built than the others. My up-to-date 
K2/100 is still in use in one of my two operating 
locations, along with the KX2. The KX3 and K3 are 
in the primary shack.


Like you I need to downsize my equipment inventory 
a bit, though the four above will stay because 
they are in use.

Phil,

That's my issue.  I just want it.  The KX1 will have to go even though I am
sentimentally attached as a field tester.  I sold off the FT K2 #35, was
sorry about it, bought another and then finally gave in and sold it too.
The KX1 is super handy but I like using SSB and had a short but eventful use
of the Yaesu FT 817 with many mods, which was so limited in many aspects
except as pedestrian mobile which gave me great success on 17m.  The KX2
looks perfect for what I love to do on occasion without the hassle and short
battery life of the 817.  I have an HT for 2 and 440 which I rarely use.
The KX3 and K3 do the rest.  The IC7000, TS2000 and KAT500 are going on the
auction blocks to make way.  I rarely use these.

Re: [Elecraft] KX2 - KX3

[Phil Wheeler]

Good discussion/comparison here 
http://www.elecraft.com/manual/KX2%20FAQ%20v-1-2.pdf


But I bought mine because I wanted one, Ruchan; 
best, small QRP rig ever, IMO.

Hi,

Since I have fully loaded KX3, KXPA100 and PX3.

Can anybody tell me why I should buy also a KX2?

Any comment would be very much appreciated.

Re: [Elecraft] KX2 Frequency display only shows 10's of HZ?

It does.

Re: [Elecraft] KPA500 age

[Phil Wheeler]

My KPA500 S/N 19XX arrived in spring of 2014 so, a 
bit over two years ago.


But I doubt any unit as recent as 1300 will have 
any age-related design deficiencies vs. a new KPA500.

I hate to bother Elecraft with this question, I am hoping someone here can

The seller claims that it is a year old and I suspect that it is much
older.

Re: [Elecraft] K2 Sidetone

[Phil Wheeler]

What Don says is right on!  I have K2/100 #380 and 
have done all the mods -- and they were all worth 
doing :-)

Frank,

That mod is not for all K2s - the K2 design was 
changed to produce a more sine-wave sidetone.  
Look closely at the information below.


If your K2 serial number is lower than 3000 - 
*and* you have not installed the K2ATOB mod kit, 
then that can be a worthwhile change.
Be aware that this published mod is quite old, 
and will cause problems if you attempt to apply 
it to a K2 above SN3000 or one which has been 
upgraded with the A to B mods.


The sidetone changes made with the A to B kit 
and K2s above SN 3000 are not exactly the same 
as this mod, but do essentially the same thing, 
but with slightly different component values.


If your K2 is below SN3000 and has not yet had 
the A to B kit installed as well as the other 
mod kits indicated on the A to B Instruction 
sheets, then I recommend you do those upgrades 
instead of just adding the sidetone mod.  The 
temperature stability and electrical stability 
of your older K2 will be improved substantially.


If the serial number is below 2560, you will 
also benefit by changing the IF crystals on both 
the base K2 and the KSB2 option for a smoother 
filter response.  Look at the markings on the 
crystals - the new crystals have a "-S" suffix 
marked on them.  If it is anything else, you 
have the older crystals.  The new crystals were 
shipped with kits beginning at SN 2560.

Seems pretty easy to do and I have always 
thought it was “my ears”.
