4K Ultra High Def version of Elecraft K4 Q&A Video Posted by NG7M

Hi everyone, I was surprised to see that Elecraft included a link to the
YouTube video I posted of my quick Q&A with Eric WA6HHQ at Hamvention. If
I would have known Elecraft was going to share the link, I would have
waited to upload the 4K version of the K4. :) If you have 4K capabilities,
you can now see Eric Swartz immortalized in 4K 60 frames per second
<https://www.youtube.com/watch?v=QakxQGFaDwA> on your high computer or 4K
capable big screen TV.

Is this overkill for an interview / Q&A video, yes... but hey, it's 2019
and the long awaited K4 has been announced, so it makes sense to have a 4K
UHD video of the K4 (Palindrome <https://en.wikipedia.org/wiki/Palindrome>).
This version is a full frame version compared to the original video. The
quality is much better and you can select resolutions all the way up to 4K
60fps (if you have the hardware to view UHD video that is).

On YouTube you can't replace a video and keep the same URL link, so I'll
leave both versions up on my YouTube channel.

Here is the new direct link if you want to see the higher quality version:

Re: 4K Ultra High Def version of Elecraft K4 Q&A Video Posted by NG7M

Wow the radio looks much more impressive in high definition. One thing I
noticed is the screen they have hooked up to the K4 looks like it is
running ubuntu. I find that very interesting. Either it wasn't hooked up to
the radio and it was hooked up to a linux box or we may have access to a
linux distro right in the radio. That would actually be cool as people
wouldn't have to use it but I would like to run logging software, WSJT-X,
fldigi for weird digital modes, etc right there on the radio. I really hope
they don't lock that down too much or give us experimenters a way to
"unlock" the radio to really exploit these features. In my opinion that is
one of the appeals for the MB-1 but the price, lack of diversity, and the
fact that it uses windows i think has turned a lot of people off.

I think it was Eric who said, in one of the recorded interviews,
that the pad controlling the K4 at "Dayton" was running Linux,
and that any device that could provide a virtual machine that
could run Linux could run the control software.

Also, Wayne posted that they would never run Windows in the K4.
And I'll bet they don't have a deal with Apple to run MacOS/iOS. :-)

Re: 4K Ultra High Def version of Elecraft K4 Q&A Video Posted by NG7M

Absolutely and I am very excited to see a top manufacturer giving what
looks like will be first class support for Linux. What I was most excited
to see though was that the radio looked like it might be running a
mainstream Linux distro. My personal opinion is that giving the consumer
the option to have access to that would really open up the possibilities
with this radio (and help many to justify the cost). If my radio can run
all the software I need for all my communications, logging, etc... I don't
have to worry how I have emergency power for the radio AND a laptop or
computer for field day or actual emergencies. I can only have a plan for
12V emergency power (battery, solar, ...) and I don't need an inverter or
generator or worry about boost/buck converters for my other non 12v
equipment. My only real fear is that before the release Elecraft would lock
that down so that the consumer doesn't have a way to at a minimum unlock
the underlying OS to use in this way. I fully understand that some won't
want to deal with the underlying OS but I also think there are many that
would. External monitors that run off 12 v are also easy found due to the
car market (

My personal opinion:

I don’t think Elecraft will provide any user modification to the computer inside the K4 box (Win-Lin-MAC).

Re: 4K Ultra High Def version of Elecraft K4 Q&A Video Posted by NG7M

In reply to this post by Jeff Scaparra

Jeff:

I took a look at the link you provided and discovered that the monitor has a max resolution of 1024 x 600. This is a relatively low resolution in today’s display environment compared to a current generation 12” laptops (such as the Dell Latitude) which has a default resolution of 1920 x 1080. Given the size of the monitor screen (10.5”) I also presume that there wouldn’t be much ‘effective coverage’ for displaying whatever software may be running.

FWIW, I run a Dell Latitude laptop in my vehicle for a variety of data decoding purposes (primarily railroad signal data, EOT/HOT and distributed power unit transmissions) that decodes packets transmitted in the VHF and UHF bands using a variety of analog and SDR receivers. Being able to quickly scan a screen and not have to scroll the screen makes a huge difference in usability and safety. Whether there are 10-12” mobile monitors that can handle 1920 x 1080 is not something that I’ve looked for. Presumably this criteria would be something that would be needed in the instance you’re outlining.

I would also suspect that whatever version of Linux may be in the K4, the real constraint would be how the effective capacity of the built-in system to manage the K4 to also handle non-K4 activities. I can tell you that the FlexRadio Systems Maestro has a built-in tablet display (apparently running a version of Windows) that has no provision for the user to run non-Flex software. If FRS were to add this capability, it would likely increase the cost of the product to provide a more robust tablet that could handle the appropriate data storage and presumably split-screen requirements. It would also introduce other potential issues in terms of security and the potential virus infection. Given that FRS controls ‘firmware updates’ for Maestro, their approach presumably reduces the prospects for nefarious intrusion.

Also keep in mind that adding capabilities such as handling data streams for various comm programs may also increase the internet bandwidth requirements when operating remotely. I don’t know what the ‘minimum’ bandwith will be to operate a K4 remote system. The K3 & K3/IO-Mini system using Remote Rig has very low requirements given that there is no panadapter/waterfall display and only audio and control are exchanged between the two units with the audio codecs configurable to take into account internet upload limitations. Given that remote operation may entail low-speed internet (e.g. as noted during the Remote Operating Forum given Friday morning of the just concluded Hamvention, “Locations with excellent internet service have poor RF conditions and locations with excellent RF conditions have poor internet service”), the ability to manage internet bandwidth in order to provide a reliable connection to operate is an important consideration. FRS has significantly improved their SmartLink system to work more effectively at slower upload speeds though it still requires more bandwidth than the K3 system (for obvious reasons-FRS has built-in Panadapter/Waterfall display).

FWIW,
