Re: [Elecraft] 32 bit Elecraft Utility Apps

[Johan Ymerson]

That is very easy to test, isn't it.
Just tried on Ubuntu 17.10 "Live-CD" (just boot the desktop ISO without 
installing).

This is what I get:
ubuntu@ubuntu:~/Downloads/k3util_1_16_6_25$ ./k3util
bash: ./k3util: No such file or directory

Re: [Elecraft] 32 bit Elecraft Utility Apps

[Johan Ymerson]

64-bit x86 Linux (or Windows for that mater) cannot natively run 32-bit 
applications. A 32-bit compatibility layer is needed. It is essentially 
an entire copy of the 32-bit version of the OS installed in parallel. On 
most Linux distributions this needs to be installed manually. On Windows 
the compatibility layer (WoW64) is installed by default on desktop 
versions and some server versions. The 32-bit support is possible 
because Intel and AMD is still including the 32-bit instruction set in 
the current CPUs. When they decide that space is needed for more import 
things (or causes too many security issues) and remove it, it will no 
longer be possible to run 32-bit applications on those CPUs.


Users with old computers can still run the older version of the Elecraft 
utilities so it isn't like anything will stop working.


By the way, if you get errors when the K3/KX3 utilities is checking for 
new firmware, try installing the 'curl' package.

Re: [Elecraft] 32 bit Elecraft Utility Apps
Yes - you are correct. It didn’t occur to me when I installed it that
it shouldn’t run due to the different architecture.
Turns out that the first thing I installed to the fresh installation
of Raspbian was Exagear Desktop to test with a different application
(a windows one.) I had thought that you had to tell ED to start the
686 emulator prior to running an x86 app, but it appears to
automatically invoke when it detects the different architecture trying
to load. So it started the emulator and runs KX3 Util inside it.
It isn’t perfect though - for some reason it fails to connect to
ftp.elecraft.com with a 127 error, even though the x86 machine can go
to the internet. KX3 Util does connect to the KX3 and can do
everything else though. Guess I’ll have to figure out how to correct
that one problem.

I expect that a some time in the not-to-distant future they will
release a 64-bit version of Raspbian. It would be nice to have a
native KX3 Util program compiled for the Arm. Raspberry Pis just get
more popular for ham radio. It runs the FL suite, WSJT-X, and Chirp.

Let's not get into a technical Linux discussion here. We hams probably keep 
old computers around way longer than the average user. The (sad) truth is that 
most people today see their laptops and phones etc as consumables that you 
through away after a couple of years.

I agree that providing both a 32-bit and a 64-bit version would be nice. But 
if Elecraft need to chose between either 32-bit or 64-bit (and two versions 
obviously cost more than one to maintain), then 64-bit is the obvious choice 
today.

Sure there are 32-bit desktops out there, therefor I wrote pretty dead, not 
completely dead ;-)
Two years ago, Ubuntu did a poll and 92% answered they used the 64-bit 
version. Now that is hardly representative for all distributions, but on the 
other hand it was two years ago...
Maintaining a 32-bit desktop is getting harder and harder. Bugs that only 
affect i386 is getting more common as hardly anyone testing new versions run 
i386. And the 3GB memory per process limit is starting to be a real issue.
The larger distributions will probably drop i386 support in a year or two.

On the other hand, the K3 Utility has to my knowledge never been available for 
ARM, 32-bit or otherwise.
32-bit Linux is pretty dead as OS on desktops/laptops. Sure, many embedded 
systems still are 32-bit, but the K3 Utility is a desktop application.

Re: [Elecraft] K3 powers off when after several minutes of 12W carrier

Yes that's my experience to. I get much better IMD at 20W than at 12 W. It

Re: [Elecraft] KX2 "HI CUR" Warning

[Johan Ymerson]

Hi,

Since it is displaying HI CUR it is more likely a short.
I am not familiar with the KX2, but other Elecraft rigs has a spark gap across  
the antenna input. These devices are designed to fail safe, ie short, if 
overloaded. Not sure how to check that on a KX2 though.

Re: [Elecraft] DMM Recommendations -- Fluke 179?

[Johan Ymerson]

There are certainly some decent cheap DMM's out there, but also some terrible. 
I had one (CH-something) that was quite accurate when the batteries was new, 
but when the battery voltage got lower, it showed >25% too much. It apparently 
used the battery voltage as voltage reference...
Combined with no low-battery indication it was quite useless.
 
So if you need to trust the readings from the DMM, get one that has good 
reputation (doesn't need to be Fluke).

Re: [Elecraft] BNC connector oddity on KX3

[Johan Ymerson]

Unfortunately there are some really crappy (cheap) BNC connectors out there, 
some with too large centre pins. Using one of those even once may be enought 
to damage the female side :-(
So when you get a new female for your KX3, have a look at all your cables and 
adapters and make sure all of them are good quality.

That can be debated, no other OS (MacOS/Linux/*BSD) identifies it as a 
microphone. And why is there no clear option to enable/disable the "software 
pre-amp" in Windows?

On the filter discussion; I have (apart from FM filter) 2.8 KHz filters and 
400 Hz filters. Very pleased with that. I am not a contester so I want the 
full SSB bandwidth, mainly for waterfall view in digital modes. 2.8 KHz 
because I couldn't be bothered with filter matching in main and sub 
receiver...
400 Hz is kind of the smallest BW usable for digital modes anyway. If you want 
to go tighter than that (for CW or possibly PSK31), use the DSP filter is my 
advice.

Re: [Elecraft] Planning the next filters

[Johan Ymerson]

Yes, the Signalink USB is 16-bit from what I remember. But on the other hand 
alost all rigs have a 16-bit audio DAC so that will be the limiting factor 
anyway (with K3 being the exception with a 24-bit DAC).
 
Probably the biggest problem with the Signalink USB is not the interface 
itself, but the Windows builtin drivers for the ADC. It thinks the ADC is a 
microphone and add +30 dB of gain in software. So those 16 bit's are quickly 
reduced to 6 bits if you are not careful. There are some descriptions (it 
isn't obvious, it is not visible in the normal mixer controls) on the net how 
to set the gain to (almost) 0 dB, but I use Linux so I haven't tried.

You see, these hobbies go well together! 
An you can always find the need for it somewhere, if you look hard enough ;-)

[Elecraft] 3D-print case for KXPD2

[Johan Ymerson]

Hi,

I just received my KXPD2 and needed a case to protect it.
Couldn't find one so I created one to print in my 3D printer :-)
Thought I share it for anyone who find it useful:https://
