Re: [Elecraft] Dusting off the old K3 & Considering a KAT3A

[Jim Brown]

Please don't perpetuate that myth, Bill.  Tuners do NOT reduce the SWR 
unless they're at the antenna end of a transmission line. The SWR exists 
on the transmission line, and it is determined ENTIRELY by the match 
between the transmission line and the load.


What tuners at the rig do is get the rig to put power into the tuner 
(and hopefully, onto the transmission line).  If the SWR is high without 
the tuner, it is equally high WITH the tuner. Depending on the cable, 
the frequency, and the SWR, much of the power that the rig puts into the 
tuner gets to the transmission line, but is turned into heat by the SWR 
in the line and doesn't get to the antenna.


A better way to talk and think about this is to say that the tuner can 
match a wide variety of loads to the transmitter sufficiently well that 
the rig can pump the maximum power from its output terminals, whether 
it's feeding a short wet string or a nice long wire we've launched into 
a tree. And if there's no transmission line, SWR has no meaning!  So SWR 
is the wrong way to talk and think about it.

If you had monocular close-up eyesight (due to scarring on one retina)
and arthritic hands (due to aging) like I have, you would understand it
perfectly.  And I don't have a work-table any more to do it right.
Luckily I had a close-by ham friend do my K2 for me. I recently had to
solder a wire to an isolated terminal, holding my breath that I wouldn't
burn myself or anything else while working under a lighted magnifier  -
something that I would do 50 years ago without a second thought.

I've paid my dues and have no regrets about having to be a plug-and-play
appliance operator.  Sure beats no operator at all.

As you get older, you will. Eyes, steadiness of hand, eye-hand 
coordination, all can make working with SMT a challenge. Mine will be 76 
years old in a few months. Several years ago, I learned just enough to 
do relatively simple SMT work with fairly large SMT components in a band 
pass filter kit. I couldn't even SEE the smaller SMT components in that 
kit, and called in reinforcements.

I actually use the toaster oven method described in QST a few years
ago.  Works great!

But how small would the K1 be if made with SMT's and a few toroids.  Ooohhh..

Re: [Elecraft] K1 Discontinued

[Eric Swartz - WA6HHQ, Elecraft]

We still sell a number of K2s each month. Its the only full-solder SSB/CW 160-10 
kit available. And its still in the upper performance portion of the charts! :-)


Plus we also still sell the KPA100 100W top cover option kit for the K2.

We plan to keep the K2 rolling for as long as possible. (And it was our first 
design, so there is some emotional attachment here..)

Hi all,

About a year after I was licensed in 2008 I was extremely unhappy with
how I was approaching the hobby. I sat there, looking at a pile of
expensive kit I had no understanding of and realized I was not
achieving my goals that pushed me to be licensed in the first place.
Those included building things, learning morse code, and developing a
better understanding.

So, I sold all the appliances and bought a K1 kit! It was a wonderful
build, and I really loved adjusting the VFO by adjusting wire spacing
on L1. So much fun! Of course, to use it I had to learn morse code, so
I did. I'm still not great, but that's just lack of practice.

I am disappointed that there have not been any new solder kits from
Elecraft and probably never will be again, though I understand the
economics, the problems with parts availability, and soldering surface
mount components.  Even so, it makes me sad.

Every time I use my K1 it makes me giddy with joy. Truly a wonderful
radio. Thank you so much for making it.

Re: [Elecraft] Drone antenna launch Field portable! Changed topic.

[Michael Walker]

I've been doing this for 5 or 6 about  years now.  Even QST published the
picture of me doing it.  We also used it for Field day.

It is a great idea.  The release is just a $3 servo that pulls a pin to
drop the weight.  You just need to be high enough to have enough inertia to
pull the drop line through the tree leaves.

For quick and dirty QRP work, I still use a water bottle on a string.

Re: [Elecraft] K1 Discontinued

[Byron Servies]

Hi all,

About a year after I was licensed in 2008 I was extremely unhappy with
how I was approaching the hobby. I sat there, looking at a pile of
expensive kit I had no understanding of and realized I was not
achieving my goals that pushed me to be licensed in the first place.
Those included building things, learning morse code, and developing a
better understanding.

So, I sold all the appliances and bought a K1 kit! It was a wonderful
build, and I really loved adjusting the VFO by adjusting wire spacing
on L1. So much fun! Of course, to use it I had to learn morse code, so
I did. I'm still not great, but that's just lack of practice.

I am disappointed that there have not been any new solder kits from
Elecraft and probably never will be again, though I understand the
economics, the problems with parts availability, and soldering surface
mount components.  Even so, it makes me sad.

Every time I use my K1 it makes me giddy with joy. Truly a wonderful
radio. Thank you so much for making it.

73, Byron N6NUL

Re: [Elecraft] K1 Discontinued

[Todd]

Up at Salmoncon this year I had a chance to play with just about every radio
Elecraft has come out with, with the exception of the K2.  I left my KX2 
sit in
the tent while I had a chance to take the K1 for a nice test drive one 
night while
sitting around in the pavilion.  Great little radio.  Wish I would have 
pulled the
trigger on it years ago!I see them quite often at different events 
for sale, usually

going for around $400 - $450

I'm sure I'll see one again this year at Pacificon - and maybe it'll 
find a place here... ;-)


Now that they're on the "endangered list", maybe that price is going 
up   :-(


Let me know Skip when you want to do Peavine (before the snow flies) and 
you can

test drive the KX2.

Later,
Todd KH2TJ

Re: [Elecraft] K1 Discontinued

[Don Wilhelm]

Mike and all,

Yes, both the K1 and the K2 have had an exceptionally long lifetime 
compared to other ham transceivers.  I received my Field Test K2 late 
1998, so my SN 0020 is 19 years old.
Even though the K1 (and KX1) have been discontinued, support will 
continue for as long as the replacement parts and knowledge base exists.


The K2 continues to be available, and Elecraft has taken some 'heroic' 
steps to provide quite usable substitutes for several parts that have 
disappeared because they are no longer manufactured.
How long that can continue is anyone's guess, but I can say that 
Elecraft is dedicated to continuing support for the K2 for as long as 
possible.


As an extension of that philosophy, I expect that those who have the K3 
will enjoy similar support for years to come.  Same for those who have 
purchased the K3S, KX3 and KX2 as well as other Elecraft products.

Don W3FPR

Perhaps I'll get around to fixing it someday.

Not many rigs (except the K2) have had a production and sales run of 17 years.  
It will be missed, but I don't know how it was kept in production that long.  I 
suspect it had a unit cost to Elecraft not significantly less than the KX2.

Re: [Elecraft] K1 Discontinued

[Jim Allen]

I found a K1 listed a day or so ago on QRZ, the same day his gripe was sent 
out, with 4 bands, IIRC, and sent the listing to the QRP list.  Whether Purley 
or anyone else responded to it, I can't say, but if he wanted one, there it 
was. As of the writing, it appears to be still available.

[Elecraft] K-1 For Sale

[KC6CNN]

I am selling my Elecraft K-1.
It has the 4 band board 40,30,20,15 meters in it. 
It also has two 2 band boards which also cover 40, 30, 20, 15 meters. 
It has the noise blanker and the automatic antenna tuner. 
The K-1 also comes with the tilt stand. 
This radio had had all the current modifications to bring it to date. 
Serial number on this K-1 is number 14, yes within the first 20 radios made. 
I am selling all of this for $500 
The reason I am selling a lot of my ham gear is because I am going to be
moving to a cabin on a ranch and we only have limited room and will operate
off of solar power. 
I have two other qrp radios and two 100 watt radios 
Thanks
Gerald

It was a favorite of mine as well.  Very capable radio that was fun to

I don't have a KPA500 (but I do have a KPA100).  If it is running as a
true linear amplifier (Class A) maximum theoretical efficiency is 50%.
I'll let the designer(s) thereof kick that around.  What do I know - I'm

Oh my!  The KPA500 is more efficient than you give it credit.   Since few have 
instruments to measure ac input parameters, will volunteer actual measurement 
figures.At 650W output into 50 ohm load, highest VA recorded was at 14.1 MHz at

 Tom,

That 3000 watts I mentioned is for everything in the station.
The KPA500 alone needs 120 volts at about 13 amps, maybe peaking to

Re: [Elecraft] Dusting off the old K3 & Considering a KAT3A

[Mike Furrey]

When I moved from Houston and house with beams to a Florida apartment but with 
a big tree outside my door, I ordered the KAT3A. The KAT3 made easy work of my 
stealth antenna on 40-6 meters.
Yes, I have a manual tuner and yes I have an LDG 200Pro auto-tuner but the 
KAT3A was a huge convenience. Go for it.

Re: [Elecraft] Dusting off the old K3 & Considering a KAT3A

[Bob McGraw K4TAX]

In a recent QST article by Kai KE4PT he describes a nice antenna for portable 
operation.  

As to 2nd floor stations and grounding, I've operated mine in that 
configuration for some 20 years.  There is no "station ground".  I do have 3rd 
pin ground in place and all equipment is  bonded to the station power supply as 
the common point.

Re: [Elecraft] Elecraft K3 lock power control

[Bob McGraw K4TAX]

I've not used ALC from the amp to control the transceiver power in years.  Just 
set the transceiver power to the required power during tune up of the amp and 
let the superior transceiver ALC do its job.  This greatly prevents ALC 
overshoot.

Re: [Elecraft] K1 Discontinued

[Raymond Sills]

Well, certainly, the handwriting was on the wall when you could no longer 
purchase a 4-band K1.  That said, I feel bad for Perley, who was saving up to 
get one.  At this point, I suspect he will have to go in a different direction, 
if he wants a rig to construct himself.  He's pretty much said that he is on a 
very tight budget, so even saving up for a KX2 might be out of the question.  
And, it appears that not too many K1 owners are anxious to put their units on 
the second-hand market, either because they plan to keep them "forever"... or 
because at a reasonable "price realized" from a sale is low enough that they 
will just keep it.  :)

Re: [Elecraft] Dusting off the old K3 & Considering a KAT3A

[Victor Rosenthal 4X6GP]

The KAT3A will make it possible to load almost anything. Definitely 
worthwhile. Even with antennas like the ones below.


You might think about an end-fed multiband antenna like this one:


It will still work if the wire is bent in numerous places. It might fit 
your "random" places.


If that's too big, here's a 40-10m version that's smaller:


I'm a big partisan of balanced antennas, but if the option is not to

Re: [Elecraft] K1 Discontinued

[Wayne Burdick]

Hi Kevin,

We should have made a formal announcement here. Yes, we discontinued it because 
certain parts are hard to come by now, making it no longer cost effective for 
us to manufacture.

It was a great product for us, and I used mine for years, taking it on many 
trips. I thought of it as a “Sierra on Steroids” at the time (referring to an 
earlier design I did for the NorCal QRP Club). But we’ve moved on to more 
versatile field radios, including the KX2 and KX3.

[Elecraft] UPS Can Be a Noise Source

[Jim Brown]

A UPS consists of a DC power supply that charges a battery, and a DC-AC 
inverter to convert the battery voltage to 120VAC.  Both operations can 
be noisy. The DC power supply is probably a swtich mode, and the 
inverter is a square wave generator that is shaped to resemble a sine wave.


Most UPS units operate in standby mode -- until power fails, the SMPS is 
charging the battery, but the inverter is not operating, and the 
equipment is connected to the power line. When power fails, the inverter 
starts operating.


A FAR better way to provide UPS for radio gear is a 12V deep discharge 
lead acid battery or 14.4V LiFePO4 that is float charged by a suitable 
power supply. And as has been discussed several times, LiFePO4 batteries 
have the major advantage that their operating voltage stays above 13V 
for most of their discharge curve, while lead-acid batteries are below 
12V for most of their discharge curve. This system is as quiet as the 
power supply used to float-charge the battery.


With either battery type, care must be taken to not overcharge the battery.

Re: [Elecraft] Dusting off the old K3 & Considering a KAT3A

Joseph,

The KAT3A has a wide tuning range, and will normally handle a 10:1 SWR.
If your SWR range is less than that, you will find operating with the 
KAT3A much more pleasant than dealing with a manual tuner.

I am a little surprised that no mention was made on this e-mail list about the 
K1 being just recently discontinued.  Or if it had, I missed it and don't find 
it in a search of the list.

It is being discussed over the QRP-L list, started by someone disappointed that 
he just finally had tried to order a K1 this past week or weekend and got the 
news.

I presume that some key part has become unavailable, or has parts deemed not

Re: [Elecraft] Elecraft K3 lock power control

[2EØLDZ]

Thanks Keith

Yes. I have been using the lock function to date.  And will carry on in that 
way.

The issue of what I am trying to do comes up as we are using an amplifier that 
is not compatible with the ALC control on the K3S therefore the need to 
minimise the risk of overdriving.  It would be nice to have some flexibility in 
that for less experienced users (especially as it is my radio I am lending to 
the club!) so that they can experiment with the power levels up to a set limit, 
without me risking my radio.

I fully appreciate that if this were in a KX500 setup none of this would be 
necessary but maybe it could be considered in a future iteration of the 
software.

cheers for the response.

Re: [Elecraft] Dusting off the old K3 & Considering a KAT3A

If the cable run(s) between the K3 & the antenna(s) is fairly short, 
it'd be a great choice.  If you've got long runs, being able to tune at 
the antenna might work better, but might also be harder to keep out of 
sight...

Re: [Elecraft] Wattage Draw - K3S/100 vs KPA500/KAT500 - for UPS

I would think this depends on the mode you operate in?

For Field Day, I operated my KPA500 (SSB only) with a 1000 watt inverter,
without any issues the whole weekend.

Subject: Re: [Elecraft] Wattage Draw - K3S/100 vs KPA500/KAT500 - for UPS

Bret,

The power rating of a transmitter is the output power, not the input draw.

If the overall efficiency is something like 33% (quite likely), then the
input draw will 3 times the output power.
The efficiency of an RF output stage alone is typically about 50%, but there
are other circuits in the transmit section that must be added and brings the
overall efficiency of the transceiver down even more.
So yes, the input power required is about 3 times the output power.

A KPA500 running on 120 volts just about maxes out a 15 amp circuit, and
that is 1800 watts input.  The K3 will need about 300 watts additional.
That means your UPS should be rated at least 2500 watts, but 3000 would be
more reasonable because it seems you have other gear in the ham station that
needs to be supported as well.

[Elecraft] Dusting off the old K3 & Considering a KAT3A

[Joseph M. Durnal]

Elecraft Operators,

I have been off the HF airwaves for several years.  Those darned antenna
restrictions really take the fun out of it.  But after helping staff the
K2BSA operation at the Boy Scout National Jamboree this summer I've really
been itching to get back on the air from home.

I have to come to grips that I'll never have a nice balanced antenna and
that I'm pretty much limited to random runs of wire here and there that can
be well hidden. Right now I have a manual MFJ tuner, but I know that got
old when changing bands or moving from the CW area to phone on 40 meters.
I also have some common second story grounding issues.  I'm wondering if
the KAT3A would be a good investment for my K3 given my situation.

Re: [Elecraft] Wattage Draw - K3S/100 vs KPA500/KAT500 - for UPS

[Larry Gauthier (K8UT)]

Put the radio and other shack items on the 2.2kw UPs. Buy a separate 220 
volt UPS for the amplifier.

Hi Bob,
I did not consider the efficiency of the power supply.  The 600W was the 
difference between his shack load with the receiver in standby and in full 
transmit.  So as you state, if the power supply is only 50% efficient, then 
276W times 2 would be close to the 600W difference.

agree that transmit is 20 amps at 13.8 volts or 276 watts.  Again with a

where near the "over 900 W".


Perhaps the computer, monitor,  lamp, printer and other ancillary 
equipment is part of the load on the UPS.  It is more likely the inductive 
load on the UPS is creating an issue with the power output indication. 
Although that doesn't explain the UPS shut down or fold back in power. 
One other issue regarding the UPS, is the output Pure Sine Wave, Modified 
Sine Wave or Square Wave?   This may have a significant impact on its 
function with various types of loads.


One way to evaluate the indication of the UPS output is to use an 
incandescent bulb of 150 to 300 watts.  They are resistive and reasonably 
accurate with regard to power consumption.  Don't use any of the bulbs 
which are "equivalent" rated ones.   I use this method as a load when I've 
had to repair any of my DC to AC inverters.

Re: [Elecraft] Wattage Draw - K3S/100 vs KPA500/KAT500 - for UPS

[KQ5S-Tom]

Understood but I believe he is talking about running everything in the shack 
off the UPS so if he buys a 2500-3000 UPS he will need a dedicated circuit 
unless he already has one.  No telling what else is on the circuit in the shack 
if it is not dedicated.

Not sure what the intent is of running the amp off of a UPS.  You will not get 
much operating time, matter of minutes, so maybe it is for surge protection.

Re: [Elecraft] Wattage Draw - K3S/100 vs KPA500/KAT500 - for UPS

[Keith Onishi]

100W of output power normally needs 200W of input power. My K3 (not S) with 
sub-RX and other options draws around 18A from DC13.8V power supply on RTTY. On 
CW or SSB, the DC current goes rapidly up and down according to the modulation.
I guess your UPS does not assume its output current going up and down rapidly, 
so its high current alarm is triggered by the rapidly changing output current.

[KQ5S-Tom]

Something is not right.  If your UPS is showing 350 with the K3S at idle and 
over 900 on transmit that is a difference of close to 600.  The K3S draws 17-22 
amps at full key down and 100 watts.  Assume 20 amps at 13.8V.  That is only 
276.  You are showing double that.

Re: [Elecraft] Wattage Draw - K3S/100 vs KPA500/KAT500 - for UPS

[Don Wilhelm]

Bret,

The power rating of a transmitter is the output power, not the input draw.

If the overall efficiency is something like 33% (quite likely), then the 
input draw will 3 times the output power.
The efficiency of an RF output stage alone is typically about 50%, but 
there are other circuits in the transmit section that must be added and 
brings the overall efficiency of the transceiver down even more.

So yes, the input power required is about 3 times the output power.

A KPA500 running on 120 volts just about maxes out a 15 amp circuit, and 
that is 1800 watts input.  The K3 will need about 300 watts additional.
That means your UPS should be rated at least 2500 watts, but 3000 would 
be more reasonable because it seems you have other gear in the ham 
station that needs to be supported as well.

baseline with K3S on RX is ~350W and it spikes over 900W with TX at 100W and
the UPS limits output. So it seems 100W isn't 100W.

I'm looking to switch in another UPS rated 2200VA/1320W, or 420W higher, for
use with the KPA500/KAT500 I just acquired from another forum member. so
from a 100W station to a 500W station. Might this work or is the increase in
watt TX not equal to the watt drawn?

Here is a quick video operating my KX2 from a tiny island feeding a 20m end fed half wave 
(64:1 transformer and 32ft of wire) hanging from a 33ft fiberglass mast. The island is in 
Huntington Lake, CA in the Sierra mtns above Fresno. Still pics can be grabbed from the 
video and near the end of the video I'm holding up the KX2 as the drone flies by. The 
caption could simply be " Elecraft Island".

The only improvement I would make is salt water for better ground 
conductivity.


...And make it count as a new DXCC country!

Re: [Elecraft] [KX3] KX2 owner discovers Heaven/P

[Bill Blomgren (kk4qdz) via Elecraft]

Truly a neat location!  The place I went for the eclipse was no where near as 
cool... a boat landing at the Congaree river..  but there were pump up boats 
going out with dogs and the like to visit vegetation islands in the river.. 
I just stayed on shore because my back and small boats do not do well 
together...
