[Elecraft] Running the K3S with a Heath SB-220

[Robert B. Weinstock]

Good morning. Does anyone have any experience using a K3S to drive a Heath
SB-220 linear amplifier? This is a 40-odd year-old amplifier with two Eimac
3-500Z tubes. My questions are: (1) What connections need to be made
between the K3S and the SB-220; how much drive is likely needed; and what
would be needed to run full break-in on CW? The SB-220 does not have its
own break-in circuitry, but there are numerous vacuum relay-based
modifications out there.

(And yes, I do have a KPA500 that I expect to use most of the time. I just
want to be able to switch over to the SB-220, which provides far more power
output.)

Thanks.

73, Bob, W3RQ

good response - tourists are odd ducks for the locals, anywhere.


Wire antennas work a lot better than verticals, esp. portable. Slopers 
are fine too.  Anything you can tune with your ATU.


Best HI portable ops I ever experienced were near Ka'anapali, using a 
random wire dangled from a rock cliff near the Sheraton Black Rock and 
pulled down to the _veryrocky_ beach nearby.  It took a while to set 
up, but didn't have to ask for permission either. Beaches in HI are 
all public access, theoretically. You may be able to use that to your 
advantage.

Re: [Elecraft] Can Anyone recommended a great QRP Antenna and Antenna Pole for KX3

[Bob Nielsen]

I once operated from a 7th floor hotel room with a W6MMA MP-1 (which 
Elecraft used to sell--the paint color on the coil matched my K2, which 
increased the mojo).  I placed it inside next to the window and made 
several contacts of 1000 - >3000 miles on 20m running 5W (propagation 
was much better than it has been recently).

support pole seem to me to be the best combination.

Yes, the packtenna pole is amazing, I used it throughout Europe this past 
summer.   My European friends recognized it as one made in  Germany.
You can't go wrong with anything George and the Packtenna crew have. 

Another choice for hotel balconies that travels nicely is the AlexLoop.

[Elecraft] KX2.KX3 Serial Port Extender

[Bill Conkling]

I have just put finishing touches on a Serial Port Expander for use with the 
KX3/KX2 series of transceivers. The device will plug into a regular or USB 
serial adapter (DE-9M) like the standard KUSB from Elecraft. 

I have posted a PDF document on my web site at http://nr4c.net/projects 
. 

I use SMD resistors and transistors to switch the DTR and RTS lines for CW and 
PTT. It also has the RXD & TXD signals use for cat control. It makes the KX 
transceivers look like a K3 to your logging software such as DXLabs and n1mm.  

The circuit board may be ordered from Oshpark.com  for 
$3.40 for 3 boards so interest a friend or two. There. Is a link in the doc for 
this service. 

I have included links to Mouser.com  for the transistors 
and resistors as well. They are very inexpensive but the shipping will get you 
if you don't order some other stuff. 

You can email me if you have any questions. 

BTW:  I have a limited supply of the transistors and resistors avail for $2.00 
for 3 each (in case you lose one) if you supply a SASE and 2 bucks. Email first 
as these are first come first served. No, I don't have any circuit boards at 
this time.

[Elecraft] Portable Antenna

[Doug Millar via Elecraft]

Well,  this works the best for me for portable. 
   From the ground up- a speaker stand, a 15' painter pole, a right angle pole 
to antenna mount, a "gum drop" antenna mount, a ham stick and two 20m radials.  
This works for 14MHz and up as the ham sticks are a good portion of a quarter 
wave.  When out in the clear it is an excellent antenna. My second antenna is a 
Buddi stick and two radials. It is smaller and easier to transport. Used the 
last time on a 9th story balcony. 
    Your results may vary. Doug K6JEY

Re: [Elecraft] Can Anyone recommended a great QRP Antenna and Antenna Pole for KX3

[sancho]

Mike, All,

I am with Fred on this call - particularly from a hi-rise hotel balcony at a 
resort. My best results have been with an Alex Walkham Magloop (has a nice 
small carry on bag that also fits in my suitcase) closely followed by the 
Superantenna MP-1 which fits in an old Targus laptop bag. I think some hotel 
management groups take poorly to 'fishing' off the 17th floor balcony of their 
prime ocean view tower. Last time I did that was the last time I'll ever try 
using an End Fed Vertical Wire hung from a fishing rod (it was a surfcaster)... 
even after dark. 

If I hadn't been a top tier frequent stay guest with the company, it might have 
gotten ugly. Some guest below reported me for dropping a camera to look into 
rooms... It was just a small weighted ball on the end of the wire. The manager 
was polite, but asked me not to do it. I was using the FT - 817 at the time so 
I luckily wound up only restricted to UHF/VHF ops and suffered a temporary 
reddened face. Glad it was a short stay.

Never had the problem with the other two antenna configurations.

Re: [Elecraft] New Sherwood Test for K3 & Flex 6700

[Michael Walker]

Correct

And this is both the advantage and disadvantage of an SDR Receiver.
Mostly, it is a big advantage and the issues get caught by the software
test team.

The great news is that it is a simple software update away from being
resolved and is part and parcel of normal software product life cycle.

The sky is not falling.

[Elecraft] Elecraft CW Net Report

[kev...@coho.net]

While twenty meters got me into Michigan, North Dakota, Georgia, and 
Japan twenty meters only got me to California.  Even though the sun is 
active right now it's a bit too active :)  Yes, we never get it the way 
we want it but I think it's going to be better tomorrow.  Unfortunately 
for us all that is the work week. So here's to the sun keeping very 
active up until Friday mid-afternoon.  Then slacking off for excellent 
conditions on Saturday and Sunday.  One can dream.

ICYDK,

Crappie [n. KRAA-pee] A genus, pomoxis, of North American freshwater 
fish in the sunfish family Centrarchidae.


Crappy [adj. KRAA-pee] 1. Of or denoting very inferior construction.  2. 
Denoting any bad condition, object, utterance, or occurrence.


"Pole" is the operative word here, fish make very poor antennas and they 
don't last very long, just as crappy crappie poles don't last long 
either. [:-)


I'm still a mag loop fan after trying all the rest.

Re: [Elecraft] What caused long reposts

[Lynn W. Taylor, WB6UUT]

If you are using Thunderbird, select the relevant part(s) before you hit 
reply.


Doesn't matter if you're in digest mode or receive each post as a 
separate message, just select the relevant parts of the message and 
that's all that shows up in the response.


A quick rule can put all Elecraft mail in a separate folder, and then it 
only takes a moment to delete mail that's not of interest.

Re: [Elecraft] What caused long reposts

[David Woolley]

If you are using Thunderbird, I believe the best way is to request the 
digest in MIME Digest mode.  As well as allowing you to page through the 
digest, it also allows you to treat the individual messages as 
attachments, so you can open up the specific  message and reply to it. 
That way, you get the correct subject, and, more subtly, you get the 
correct In-Reply-To header, so that forums and good mail clients can 
properly place the reply in the thread.


That's how I do all replies to this list.

(Note Thunderbird does have some bugs, e.g. I had to delete a redundant 
"Re:" from the subject.  It can also be a little fiddly working out 
which instance of the subject is the correct one in the attachments.)


Unfortunately, the top posting policy of the list reduces the incentive 
to trim posts, meaning people who do end up quoting the digest don't 
think about pruning it.  Failing to prune is also bad for readers of the 
digest, as they have to page over the complete back thread.


This has been top-posted, but also pruned, as it would be for an 
interleaved posting (popularly called bottom posting, although not 
everything need be at the bottom).

I understand that those steps are more difficult on a smartphone.  It is
easy when using an email client like Thunderbird.  As I have stated, I
suggest receiving individual emails and sorting them into an Elecraft

of deleting a lot of information.  I do not receive email on a
smartphone, so I don't have any suggestions for handling that.

Re: [Elecraft] Future KX3/KX2 accessories?

[Walter Underwood]

Any off the shelf stereo to mono splitter will do that. That also gives cleaner 
bias for the mic. Details in this blog post.

https://observer.wunderwood.org/2015/08/16/yamaha-cm500-headset-with-ptt-on-elecraft-kx3/
 


On the KX3, PTT does not need to be across the rings. Ring 2 (logic ground) is 
tied to the shield (audio ground) inside the radio. I hear that the KX2 is 
wired the same as the KX3.

Re: [Elecraft] Can Anyone recommended a great QRP Antenna and Antenna Pole for KX3

The MFJ 2286 Big Stick Vert. may be what you are looking for. Nocks down to 
about 28” and extends to 18’
I have used it as a 20 meter GP. works well.

Re: [Elecraft] SSB Net

[kev...@coho.net]

I just called the 20 meter Elecraft CW Net.  I worked folks in Michigan, 
Georgia, North Dakota, & Japan.  QSB was strong except to the West, the 
JA was blasting in at S6 with weaker QSB. Waves of QRN were passing 
through the band which wiped it out for a few seconds too.  100 watts on 
CW works pretty well when the band is passable.

Re: [Elecraft] KAT500 tuning behavior when the load is impossible to match ?

[Wes Stewart]

It's easier with a tuner that has lossy components. It's really easy with a tee 
tuner with three adjustable components.  There are many matching solutions, only 
one of them is the lowest loss.

Re: [Elecraft] K3 microphone settings

[Alan. G4GNX]

Thanks to all who sent in their favorite macros. They all make sense and I 
will implement one very shortly.


The other day I tried to setup bias on the rear panel and no bias on the 
front panel manually in the menu and there was something strange going on, 
where whatever I set on one panel was copied to the other one and even when 
I changed one to it's opposite, that got copied to the other one.


I have yet to verify this as I haven't had time to do so, but I'm hoping it 
was just a senior moment illusion. :-)

Re: [Elecraft] KAT500 tuning behavior when the load is impossible to match ?

[Ron D'Eau Claire]

To answer your other question, if the KAT500 cannot find a match better than
1.5:1 the FAULT indicator on the front panel will light. You will also
trigger a fault if:

1) The RF power is above 110 watts while tuning to protect the relays from
arcing. 

2) The impedance can be matched but is outside of the KAT500's normal tuning
range with an impedance that may produce RF voltages that could damage the
components considering the RF power applied. In that case, the fault occurs
when you raise the RF power. However, it is safe to operate at any power
level below which the fault occurs.

Re: [Elecraft] New Sherwood Test for K3 & Flex 6700

[Richard Lawn]

There has been a tremendous amount of flap, angst and drama on the Flex
users group about these results, so much so that Gerald got involved to try
and get to the bottom of it. Apparently there were some software changes
made with the last or previous SmartSDR upgrade that did some harm. They
know what happened apparently, which is way beyond my capability to
understand or explain, and are in the process of making the changes and
improvements Gerald found and these changes will be implemented in the next
SmartSDR version. I guess at that at some point Sherwood will re-run tests
and post new findings which hopefully will look like the much earlier
evaluations.

Pole for KX3

Hey Mike.

For a trip to ZF last month, I took several old Walmart crappie pole pieces and 
built a 22 foot mast by judiciously selecting and cutting pieces no longer than 
28 inches so that the sections would stack and the disassembled antenna would 
fit diagonally in my suitcase.   

I'm hoping that has forever solved the air transport of fiberglass mast 
problem.  Its not as bulky as it might seem because the narrower pieces stow 
easily inside the wider ones.  And Walmart crappie poles aren't exactly heavy 
duty.

I did find that unless you are good with puzzles, it is a really good idea to 
number the sections in order of assembly.  Don't ask..

As far as high rises go, if you can get a wire 6 feet out and drop it 
vertically it can be an amazing low band antenna - you need a weight on the 
bottom that can't hurt anyone, like a hotel size plastic shampoo bottle or a 
small bean bag like the tree maintenance guys use, and if you land the weight 
on the ground somewhere out of the way, rather than letting it swing or be near 
a pedestrian pathway, you are much better off.  In that case some monofilament 
for the last ten feet or so keeps the rf away from whatever is there on the 
ground.  My kx3 rarely has any trouble tuning that set up if you throw a 
counterpoise wire around the balcony or can ground to a railing.

Have fun.

Re: [Elecraft] reply to digest

Not a victim here, I delete without reading over 90% of the email I get.
And my ISP has pretty good filters for spam. Just saying for those that
think everybody reads their reposted digests that some of us don't. They
are the ones wasting their time.

Re: [Elecraft] Can Anyone recommended a great QRP Antenna and Antenna Pole for KX3

[Fred Jensen]

"Great" and "QRP" in the same sentence is an oxymoron if QRP implies 
portable packed in by a human. [:-)  About the "best" I've found for 
other than Class 4 mountaineering is a small mag loop.  I use an 
Alexloop [a little pricey] but they are easy to build for very little 
expense.  If you do choose to build one:


1.  Voltages/Circulating currents can be surprisingly high in loops, 
even at QRP.


2.  Use a capacitor with a 10:1 reduction on the shaft.  They get real 
touchy on 20 and below.

Re: [Elecraft] Can Anyone recommended a great QRP Antenna and Antenna Pole for KX3

[Scott McDonald via Elecraft]

Hey Mike.

For a trip to ZF last month, I took several old Walmart crappie pole pieces and 
built a 22 foot mast by judiciously selecting and cutting pieces no longer than 
28 inches so that the sections would stack and the disassembled antenna would 
fit diagonally in my suitcase.   

I'm hoping that has forever solved the air transport of fiberglass mast 
problem.  Its not as bulky as it might seem because the narrower pieces stow 
easily inside the wider ones.  And Walmart crappie poles aren't exactly heavy 
duty.

I did find that unless you are good with puzzles, it is a really good idea to 
number the sections in order of assembly.  Don't ask..

As far as high rises go, if you can get a wire 6 feet out and drop it 
vertically it can be an amazing low band antenna - you need a weight on the 
bottom that can't hurt anyone, like a hotel size plastic shampoo bottle or a 
small bean bag like the tree maintenance guys use, and if you land the weight 
on the ground somewhere out of the way, rather than letting it swing or be near 
a pedestrian pathway, you are much better off.  In that case some monofilament 
for the last ten feet or so keeps the rf away from whatever is there on the 
ground.  My kx3 rarely has any trouble tuning that set up if you throw a 
counterpoise wire around the balcony or can ground to a railing.

Have fun.

Re: [Elecraft] Can Anyone recommended a great QRP Antenna and Antenna Pole for KX3

[Kevin - K4VD]

​End fed... I can throw it up about anywhere I go at a moment's notice and
make CW contacts at 5 watts with little effort. It packs small, works in
pretty much any position, easily repaired, fits in a camera bag with the
radio, battery and everything else needed for a day of fun.

Yesterday I was at Mason Neck WWFF KFF-1308. Dragged one end up a tree
almost vertical, ran between 3 and 10 watts and worked 14 stations
including Belgium with minimal effort. Time from start of setup to on the
air maybe 10 or 15 minutes.

Whatever other antenna you may find, it still might be worth bringing an
end fed along.

I heard some 7-land stations down in the noise on my KX2 and a Chameleon
Loop from a lookout 1,980' above San Jose, CA. But as weak as they were,
I knew I didn't have chance to be heard using QRP power.

Re: [Elecraft] [OT] Morse is back!!

[Fred Jensen]

I believe this became the required keying device in the Poisson du Avril 
contest some years ago. [:-)


I had a Morse SMS message composer on my Android phone several years 
ago.  Send Morse to it with two fingers and it created a text message.  
It's not there any more, it was a solution lacking only a problem.


If, however, you are an ARRL member, in the Oct 1949 issue of QST, you 
will find an article introducing the secret to perfect Morse ... 
keyboards, other than typewriters and teletypes, and electronic keyers 
were yet to be invented.  It used a four-finger switch arrangement, and 
the author, one A. F. Scotten, W6ZMZ, even offered a sentence to prove 
its superiority: "Then after Richard had arrived he and Clarence each 
kissed beautiful annabelle and she ceased all resistance because in 
actual fact she liked it better than ever


Ignoring the fact that is is a fairly racy sentence for QST in 1949, he 
asserts it has no consecutive dashes and is thus very hard to send on 
the keys/bugs of the day.  The secret to perfect Morse?  Send the spaces 
instead of the dits and dahs.  For some reason, the idea never caught on.

Re: [Elecraft] Electricity and worms [was: KAT500 tuning behavior when the load is impossibleto match ?]

[Alan. G4GNX]

FWIW back in the 80s, I had installed a new ground plate for the shack and 
wanted to ensure that it really was the best ground possible.
I used a trick that was used by the telecom people, where they connected the 
local exchange battery across two plates and blew off all the crud. 50 volts 
at many hundreds of amps did the business.
My way was to connect my ground plate to the incoming 240 volt supply main, 
via a MCB and each time the MCB tripped, I substituted  bigger one until I 
had no more larger values. ISTR I got to 40 amps and settled for that.
I had obviously made sure that no person or animal could get near the area 
whilst the power was on, but I was quite surprised to see how many 
earthworms had scuttled their way to the surface.

Re: [Elecraft] KAT500 tuning behavior when the load is impossible to match ?

[Mike Rhodes]

No practical experience with the KAT500 but can tell you that, years 
ago, while guest operation at a contest station, a 160 meter vertical 
was strung up between a couple of the towers. The operator went in and 
successfully tuned the antenna to a 1:1 match and then loaded the KW amp 
to full output. He then went S&P to get warmed up but heard very little 
and could not work any of the few stations he did hear. We went out and 
discovered that the vertical wire had snagged on the ground rod! The 
tuner was manual but imagine the same principal applies. Yes, you can 
often get a "perfect" match but that may not count for much! Have often 
wondered if the earth worm population in that area ever recovered.

the dummy load was disconnected (because I was moving things around).

OK, fixed that little problem but I was curious about the behavior when the 
KAT500 tuner is faced with an impossible match. Does it give up?  I assume it 
gives up but then I didn’t see anything to indicate that the tuning operation 
gave up.  In fact, it seemed like it found a tuned LC solution but one that was 
matched with a bypass of 54:1.

My first question:  If KAT500 fails to find a valid solution does it report an 
error.  I ask this because at times I have had red LED lights flashing on a 
failed tune but I did not have one this time.  I am wondering if I missed the 
error report on the utility program.

My second question:  Is it possible that the KAT500 did resolve a tuned LC 
solution with basically 6 feet of coaxial cable unconnected with anything?

Thanks,

writing a macro to use one or two buttons to implement this.

My problem is that each microphone requires a different gain setting
and when manually changing the menu settings between front and rear
panel, the gain settings don't track and have to be set separately on
the front panel gain control for each microphone.

Does anyone know if it's possible to change the mic gain setting as
part of a macro and possibly compression levels as well?

Re: [Elecraft] kx3 px3

[Fred Moore]

Fred:  Turns out I had already read everything you suggested, and did
correctly understand the compensation, however...

-73dbm at the antenna, signal generator only (no noise)

does =S9 on the KX3, and does not = -73dbm on PX3  (Lvl Mode = scale:db)


Per PX3 manual page 23 bottom right paragraph 5th sentence down:

"The indicated dBm level should be the signal level at the signal level
at the KX3 antenna input" 


In my case this is not true, I am seeing about a 10-12dBm difference. 
In my previous post, I referenced S9 and 50 microvolts, thinking most
people on the list are not use to referencing dBm, that was my error.
After re-reading my original post I even said mV when I intended
micro..  I should have been more specific, and correct..


I do not expect the PX3 to be a precision instrument, however I am
trying to resolve and understand a 10+db error here, huge to me, which
should not exist according to the PX3 manual, but may be in the PX3
specification if its specification is +-10%.  As a side note the PX3
scale does appear to be linear, relative to dBm, i.e. the error is the
same through the usable scale..


If that is normal I can live with it, I simply want to understand if
this is what others are seeing.. and make sure this new to me PX3 is
operating correctly..

[Elecraft] New Sherwood Test for K3 & Flex 6700

[Bill W4ZV]

http://sherweng.com/table.html

Sounds like Rob is working on a new talk for Dayton...probably comparing
testing of direct sampling vs traditional receivers.  Note the "ag" and "ah"
footnotes for dynamic range (at both 2 & 20 kHz) at the bottom of the
comparison chart.  New K3S result is #3 on the page and new 6700 result is
#12 on the page.

ag  DR3=96 dB with 20 dB Preamp ON. (99 dB Preamp OFF) Otherwise dynamic
range independent of signal spacing.
NOTE: Testing of 2nd sample made on 10 meters while investigating IFSS*
curves. Similar testing of 2nd sample of K3S, also made on 10 meters. * IFSS
= Interference free signal strength.

ah  NOTE: Testing of 2nd sample made on 10 meters while investigating IFSS*
curves. Similar testing of 2nd sample of Flex Radio 6700, also made on 10
meters. * IFSS = Interference free signal strength.

73,  Bill  W4ZV
