K4 Panadaptor Display

Thanks for the quick answer Grant (& also Ed W0YK).
That is more than a little disappointing as it means that as a contester for example, you either have to have two or more displays (ie. One for a logging program & one for the K4 display) or buy a much more expensive display which enables you to have separate quadrants for separate programs? This seems a rather retrograde step compared to most other current transceivers or have I misunderstood? I suppose you could use the touch screen display as an alternative but why not output the K4 display to your PC and then put both outputs onto a single screen?

Re: K4 Panadaptor Display

I display, whether physical or logical (e.g, a quadrant of a real display), only supports a single input — it has no means to “window-ize” multiple inputs.

Thinking about this some more, it seems it should be possible, eventually, to put a piece of remote software on the same machine that runs your other radio apps, and accomplish what you want to do. You can still only have one display controlled by one computer, but that one computer could be running multiple apps including a remote K4 display in a window.

What about running the pan output through a VNC in a window? That brings up the question will the K4 have a VNC server on board?

Re: K4 Panadaptor Display

There are numerous sources of HDMI capture adapters that looks like
webcams to the PC (e.g. https://www.adafruit.com/product/4669). Feed
the K4 output to one of these and then you can do almost whatever you
want with it.

This thread seems to be trying to re-invent the wheel. There are solutions
already available.

According to the K4 Programmer's manual (available from the elecraft web
site), "The K4 provides three kinds of streaming data: ..., dB/bin (for
reproducing panadapter data), ..."

This kind of dB/bin data can be used by a logging program to create a
spectrum/waterfall display integrated with the rest of the program,
supporting features such as display of call signs with multiplier.worked
before status, and jump-to-signal capabilities using keyboard hotkeys or
mouse clicks, all without looking at or touching the radio. N1MM Logger+
has had this kind of capability for nearly four years, taking advantage of
dB/bin data supplied in the radio control stream by some radios (e.g. Icom
IC-7300 and newer) or in a UDP stream from a radio or from other software
(the UDP protocol used by N1MM+ is documented at <
https://n1mmwp.hamdocs.com/appendices/external-udp-broadcasts/#sending-spectrum-data-to-n1mm>).
There are other logging programs with some of the same capabilities, with
no need for VNCs, HDMI capture, fancy picture-in-picture monitors, etc.

Mike,

Good idea.

Looking at HDMI capture "cards" - I found many on Amazon and a number
had audio I/O, too.
Meaning... A Zoom meeting, video and audio from the K4 as a training
"session" for FD...

(say it four times! "we will have a K4 for FD...)

I can also "see" HDMI & K4 as a group demo to a large TV for other radio
events, like JOTA.

I see lots of inexpensive devices like this $27 that take multiple HDMI and provide picture-in-picture.

https://www.amazon.com/Switch-Splitter-Selector-Remote-Control/dp/B07PTYJQQ1/

Now I’m wondering how well one of these would work with P3/SVGA using a VGA to HDMI adapter?

When I left TV broadcasting in the early 2000s, we had 2 & 4 way splits on
some hd monitors using an interface device (can't remember its name).
For an enormous sum, we could have as many displays as we wanted on the
largest displays available. I know because my production manager wanted to
redo the monitor wall for the main (News) studio control room and put it in
the budget every year!

Found a solution for a 4 way split on Amazon:
Amazon.com: gofanco Prophecy 1080p Quad Multi-Viewer 4x1 HDMI Switcher with
Seamless Switch, Split Screen, 5 Display Modes, Audio Extractor to Stereo,
IR Remote/Software/Push Button Selector (PRO-QuadView): Electronics
<https://www.amazon.com/gofanco-Prophecy-Multi-Viewer-Extractor-PRO-QuadView/dp/B07SQGD95C/ref=asc_df_B07SQGD95C/?tag=hyprod-20&linkCode=df0&hvadid=366299657667&hvpos=&hvnetw=g&hvrand=3903636579611039755&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9011011&hvtargid=pla-791028447790&psc=1&tag=&ref=&adgrpid=74513439085&hvpone=&hvptwo=&hvadid=366299657667&hvpos=&hvnetw=g&hvrand=3903636579611039755&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9011011&hvtargid=pla-791028447790>
for
$120.
No clue if it is any good; but solutions are available. This one does give
some limited options.

I think this entire subject has been thoroughly over thought. Granted, I did not read every post because of the redundancy. Hopefully I'm not guilty of the same.The issue seems to be a resizable window. If you use the K4 utility, (I'm not sure if it's fully released) it will give you a resizable utility window that includes the spectrum display. That seems to me to be the simple solution. Am I missing something?73,Gary KC9EE
