Re: [Elecraft] K3 UOS?

[Bill Frantz]

On the Teletype model 33 and 35, one character delay was enough 
for the carriage to return to the left margin. That made the CR 
LF sequence the favored new line. (The LF could be executed in 
one character time.) These machines used ASCII code as compared 
with the model 28 and earlier models which used the Baudot code 
we use for RTTY. I understand that these earlier machines had 
the same timing, but I never had any direct experience with them.


Indeed, if you used the LF CR sequence, you needed to insert a 
one character time delay for timing. A Rubout character was 
often used for this delay.

No RTTY QSO's in years but have functional setup for receive, K3 audio to a 
Timewave 59Y driving a model 15.  Great demo and conversation piece for visiting

Re: [Elecraft] K3 UOS?

[Lynn W. Taylor, WB6UUT]

On a Model 15 or 19, you could see the mechanism move on a  or 
 character.


On a 28, you could see the typebox shift positions.

In software, it's the same: you have a 5 bit baudot character and a 
figs/ltrs state, they're read, decoded and the appropriate character 
"printed" on the display.


I'd expect the encoding algorithms to follow the best practices while 
sending and decoding to handle all the odd variations that might be out 
there.

[Elecraft] Macro Spread Sheet Update

[Dave Cole]

Hello,

For those of you who put together a Genovation external keypad I have
updated the Macro spread sheet located at:

http://nk7z.net/adding-an-external-keypad-to-the-k3/

About 3/4 of the way down the article you will find a link to the new
spreadsheet.  

Macro 35 sets the K3 power to 25 Watts, and Macro 36 Sets the K3 power
to 100 Watts.  The template for printing Generation key caps has been
updated to reflect the two new commands.

If you did not do a Genovation Keypad, the macros are still good to use
if you enter them into the P3.

Re: [Elecraft] K3 UOS?

[Ron D'Eau Claire]

In pre-history (when the Model 19 was state of the art) we simply hit LTRS 
several times after sending figures to be sure it was received. Also, every 
line of text ended with a Carriage Return - Line Feed - Letters key sequence to 
be sure it was ready for more text.

Re: [Elecraft] K3 radio no receive no transmit

[Don Wilhelm]

John,

Don't forget to check the connections on the outside of the K3 as well.  
A loose PL-259 connector could cause that same behavior.
PL-259s need to be tightened finger tight, and then given just a little 
bit more tightening with pliers to assure a good connection to the coax 
braid.

I asked in private email.

It is "Unshift On Space". I assume it means go back to letters

Re: [Elecraft] [k3] Isotropic Antenna

[Jim Brown]

This so-called "antenna" is at best dumb, and at worst a rip-off. As 
master antenna-designer N6BT wrote some years ago, "everything 'works,' 
even a light bulb." He demonstrated this by mounting a a light bulb on a 
wooden fencepost, feeding with coax that he had carefully choked so that 
the coax could not radiate, and working all continents with it.


As others have noted, antennas like magnetic loops, loaded whips 
(HamSticks, etc.), and long wires are the weapons of choice with limited 
space and/or requirements of minimal visibility. If the frame of the 
building is non-metallic, indoor antennas can work (but can also be 
mondo noisy on RX). If the frame is metallic, the antenna must be 
outside. The good news is that the building frame will work fine as a 
counterpoise (although it may block the antenna in the direction of the 
building).  A long wire launched away from the building is best -- small 
diameter enameled wire can be hard to see, and works fine as an antenna.

grounding availability, bandwidth was very small and tunning was influenced
by ground only but also by closed objects a lot.

Re: [Elecraft] KPA-500 and a K2

[Jack Brindle]

The KPA500 is linear, with 13 db gain. That means the KPA should output about 
20 x the input power.
So, for 5 watts in, you should get about 100 out, for 10 in about 200 out.  
There are slight variances due to the KPA's input network.
Also, be sure to check what the  transceiver is putting out compared to what it 
is indicating. Amazing how often power calibrations are needed.

Windows?  I thought we were talking about Linux!  At least that is what
I inferred from the thread.

I was specifically referring to the present Linux utility tarball on the
Elecraft download page.  It is for the i386 architecture only.

Re: [Elecraft] low IF out on K3

[Ron D'Eau Claire]

Older K3 transceivers (built before September 2009) do have lower output
than later units. Elecraft published a modification that involves replacing
a single resistor to bring up the level. 

They have a kit that includes an SMD and a leaded resistor (you can use
either, only one is installed). Order the KIO3BUFFKT. You can see what is
involved by reviewing the instructions available for download here:

http://www.elecraft.com/K3/mods/IF_Output_Buffer_Gain_Mod_Rev_A.pdf

If you have a 13K ohm, 1/8 watt leaded resistor or if you'd rather work with
an SMD, a 13K 0805 size resistor, you won't need the kit.

Re: [Elecraft] KX3/PX3 Linux Utilities for Raspberry Pi?

[Bill Frantz]

I have a BeagleBone Black based system set up for low power 
portable operation in digital modes that I built in 2014. 
(Information and photos available on request.) When I last 
considered asking Elecraft for ARM versions of the utilities, I 
thought the number of possible users was too small to be worth 
their while. The number seems to be growing, so now it may 
depend on how hard it is to support all the ARM platforms, or at 
least the most popular ones.

How old is your K3?  I believe they made a change to increase the

At this time not even amd64 builds of the Elecraft tools have been made
available so I run them in a i386 VirtualBox instance of Debian Jessie
on the odd occasion I need to use them.

They're not usually installed by default but are available via the
package manager of choice (in my case that is Aptitude).  As I recall
the build-essentials package is a meta package that includes most common
build tools as dependencies.

The Pi Foundation has made sure that the Python support is very good.

[Elecraft] Desoldering with ChipQuik OT

[Fred Townsend]

There has been much discussion of desoldering techniques. Many express their 
praise of various desoldering/soldering machines. However machines have many 
negatives starting with the need for a high degree of skill and expense. In 
short they are not practical for the once a year project builder. 
ChipQuik is a good tool for the occasional builder. It's cheap in the sense you 
don't have an expensive tool sitting on your shelf just drawing dust. Also in 
terms of temperature extremes it's easier on the de-soldered part. 
The big negative for many is ChipQuik is it is not intuitive (at first). Its 
use also needs companion tools such as a solder sucker or SolderWic(k), also 
inexpensive tools, and of course a soldering iron. As the saying goes one 
picture is worth a thousand words so see the video.

The YouTube link below is one of the better tutorials. (Forgive the VK accent) 
https://www.youtube.com/watch?v=UmD7F0--7Lc=False

If you want to buy the stuff let your fingers thumb through the Internet. You 
might be able to get a free sample. Disclaimer: I make no vendor endorsements 
nor do I have any fiduciary interests in the product.

Re: [Elecraft] KX3/PX3 Linux Utilities for Raspberry Pi?

[Bruce Nourish]

On this mailing list, I recently requested a similar thing, namely a
cross-platform command-line firmware updater for all Elecraft devices,
specifically one that includes Raspbian. I did not get a response from
anyone at Elecraft. Obviously, my suggestion is not quite the same thing as
what Andy is asking for, but it must be very clear at this point that
plenty of people have their rigs hooked up to their RPi's, and it would be
nice to have some Elecraft software for that use.

Re: [Elecraft] KX3/PX3 Linux Utilities for Raspberry Pi?

[John Pitz]

I would find a KX3 utility program targeting the Pi to be helpful too.
I would find it especially helpful if the KX3 utility was made open
source, then we could compile it for any platform we wish.  Plus, I
could take care of a certain, irksome programming error...

Do the linux distros for it come with the dev. toolchains like GCC in them

Re: [Elecraft] S: Re: KX3/PX3 Linux Utilities for Raspberry Pi?

[Andy McMullin]

Hi John (et al),

For my display with this one I’m using the original HDMI-Pi screen — the 
original was not a touch screen but measures 9 inches on the visible diagonal — 
with its own PSU (12v into it drives the screen and supplies 5v for the Pi) and 
case. The bad news is that, although the case looks lovely being made of 
coloured plastic, it seems to be totally transparent to anything from the 
Pi/screen that might cause any sort of QRM. Oh well!

The case design is OK but it leaves the USB pointing downwards with little 
space for the KX3’s USB lump. However, a pair of right-angle USB 3 adapters 
from Amazon fixed that one for me. Being a Pi-3 I use the internal WiFi for 
internet and the rest, leaving one USB spare when I have one for wireless 
keyboard/mouse, one for the the KX3 and one for a Signalink-USB as the 
soundcard.

I’m using the Ubuntu Mate version of the OS on the Pi and the only issue I 
have/had with WSJT-X is that it sometimes fails to start at all unless it’s run 
with administrator privileges. But that’s only happened since the last library 
update so it’s obviously a permissions thing I’ll need to fix "one day”. As you 
might guess, at the moment I need the internet for the RTC synchronisation for 
JT65/JT9. However, I’ve ordered an add-on board that includes a better RTC as 
well as UPS functionality. 

I have another Pi (a Pi 2) with a 5-inch touch-screen from Amazon (actually a 
company called Waveshare) BUT the screen has its own special drivers which 
don’t seem to be available for versions of the Pi OS since last May. They’ve 
made pre-built OS images with all the stuff included available for download but 
the images are “ancient” (and won’t work right with a Pi 3) and include a load 
of stuff I don’t want. The company don’t seem to want to respond to requests 
for driver information either so I’d avoid that particular screen is you can.

Anyway, I hope your experimenting goes well too. Would you vote for the KX3 
utility available for the Raspberry Pi?

— 
Regards
Andy, G8TQH

Re: [Elecraft] KX3/PX3 Linux Utilities for Raspberry Pi?

[Brian Waterworth]

Yes, I asked about a year ago.  The answer back was no and Elecraft, at
that time, had no plans to provide an RPi version nor provide the source,
in order for us to build on that platform.

I will throw my hat into the ring and request the Elecraft KX3/PX3
Utilities for the RPi (Raspian - Jessie).  I am moving more and more to the
RPi for all my Ham app needs for the KX-line.  The KX3/PX3 utilities are
the last hold out for me to have a complete set of programs to manage the
KX3/PX3 from the RPi platform.  I have to switch to another computer (x86)
in order to perform any KX3/PX3 utility functions.

[Elecraft] KX3/PX3 Linux Utilities for Raspberry Pi?

[Andy McMullin]

Hi All,

I’ve had a go at searching back through the archives, but couldn’t find the 
question being asked, let alone the answer so here goes….

The Linux versions of the utilities are for an X86-based machine. Has anyone 
asked for them to be recompiled for an ARM machine? In particular, now that the 
Raspberry Pi 3 is about — with astounding performance for the price (at only 
£25) — for Raspbian?

I’ve got my Raspberry Pi 3 running WSJT-X and FLDIGI just fine to my KX3. With 
a small screen and suitable supply it makes a fine 12v-based portable system. 
It would be nice, therefore, if I could also use the same small machine for any 
firmware updates, Macro settings and to work CW etc direct with the KX3.

BUT, is it just me? Anyone else interested?

Re: [Elecraft] KX3 VFO B skipping

[Don Wilhelm]

It is most likely that the encoder must be replaced to correct that 
behavior.


The VFO B encoder is a thru-hole part and can be replaced if you have 
good de-soldering tools and work very carefully so you do not damage 
anything else around it or damage the board or the SMD parts that are in 
close proximity to the encoder solder pads.
Reverse the steps in the assembly manual to tell you how to get to the 
encoder and front panel board.  Make careful note of the screw size and 
length in each place you remove a screw.


If doing that gives you pause, then let the techs at Elecraft handle it 
for you - it will be worth the price.  Contact support to initiate the 
RSA process.
If you just want to purchase the encoder and do it yourself, you can 
contact pa...@elecraft.com directly.

Don W3FPR

 主題︰ Re: [Elecraft] [k3] Isotropic Antenna
   
Hi Bruce and others,

I am sure that David talked about an Isotron antennas like this:
https://www.isotronantennas.com/

I intensively tested/used this antenna in 90's on 40m (product from Sigi,
DK9FN) and I have to say it is a nightmare in overall. From my own
experiences the performance of this toy was highly dependent to the
grounding availability, bandwidth was very small and tunning was influenced
by ground only but also by closed objects a lot.
Also the weather changes made bad impact for SWR like snow, rain etc. 
Finally in 90's this toy was quite new and like any fashionable piece it was
really overpriced.

David,

As you can see the price these days is not so high but I do not believe that
something changed in its performances. If you would like to spend time with
playing around it (instead of enjoying the on-air operation) then you can
build it ownself as there is nothing magic on it. In any case do not waste
your money with buying it.

Hope it helps,

73 - Petr, OK1RP

Oh, I miss-interpreted this.
The meters are useless during reception and waste a lot of space.
