Re: Display incomplete on Windows-11

My screen is 2048 x 1152. Admittedly a strange resolution. My PC said it is the recommended resolution for my hardware. I tried it at 1920 x 1080 and it still is cut-off.

I have that same problem. I'm running 1830 on a Windows7 machine. I played around with all sorts of settings trying to get the complete display. I then saw the sdrsharp.layout.xml file. I deleted it and figured when I restarted sdrsharp it would re-create that file. It did and I had the full display. I thought, aha something in the original file was messed up. So to be sure I saved my layout as ... mylayout. Only problem was, the next time I started up sdrsharp it went back to the truncated display. I tried using the default layout AND mylayout. Nothing mattered. I tried deleting the sdrsharp.layout.xml file again and re-starting... nope still cut-off. I don't know what the deal is but I went back to sdrsharp 1700. I have no problems with that interface. There's just something that is too flakey about the Telerik interface.

SDR # works well on win 11 pro. Both HF + Discovery and R2. I did the update more than a week ago.

Hi Dasvid,

I got a message from Microsoft as well, that I could install Windows 11 for free  but I hesitated to do so fearing for problems in our softwares 😕

Please let us know when you encounter more problems.

Thank you

SDR# 1830.

This was a fresh install of 1830.

Looks good! Resolution is a good point, but with programmers moving to
"27-inch 4K" screens being able to fit everything on with smaller displays is
an important consideration.

Wish I'd seen that one myself!

I picked up a virtually brand new 8 GB 6th gen i5 Surface Pro 4 off of the Facebook marketplace for £200 which runs SDR# and my Airspy at 10MSPS flawlessly.


Re: Windows 10 Tablet Recommendations? #win10

Here's a page with a lot of pertinent information:

https://www.zebra.com/us/en/support-downloads/tablets/xslate-b10.html

It appears that it is Realtek HD Audio which I *think* maxes at 48000. There is an extra USB port though, and there are external cards by Startech which are pretty small yet support 96000. They can be a little quirky but they work well once they're set up.

Once I know the setup is working properly I may do some dismantling to see if there's any room to install a chassis mount BNC connector with a short piece of RG178 or similar and a few RF chokes, and maybe the same for a short USB cable to connect the Airspy device, although the mini will have to remain outside I think as reviews of this indicate it can run pretty warm. But, first things first...make it work and then go from there.

Thanks for sharing that, Scott.  That looks like a nice platform for an SDR application, and the price is pretty attractive as well.  It would be interesting to know what audio chip is used in the integrated sound card, and what sampling rates it supports.  In most cases, an audio sampling rate of 48 ksps is more than adequate for listening, and even for many digital mode post-processing software products like fldigi, MultiPSK, wsjt-x, etc.  However, I seem to recall that some of the software used to process weather satellite images and other types of images are better suited to audio sampling rates of 96 ksps or 192 ksps.  Even if the on-board sound card didn’t support the higher audio sampling rates, an add-on USB sound ‘dongle’ might provide a solution to give you the higher sampling rates if you need it.

 

Keep us posted on your experience.  Thanks and 73.

That's great advice, Simon. Unfortunately I'm not a programmer, at least one that's capable of authoring plugins. So I can only hope that a simple change could be made that will let me make use of the SNR logger without having to turn off decimation altogether, tanking my dynamic range.

Then again, if SDRC had noise-based squelch like SDR# I could just use your app & be done with it.

In search of: Current or recent Windows 10 tablet that will support the above.
I would prefer to avoid Microsoft Surfaces as they appear to be "rather
overpriced". I have searched in the group for tablet information and found some
threads that are older but nothing really current. It would be used for this
dedicated purpose and as such would not need to run any other software
concurrently. I'm hoping something with 4 or 6 GB of RAM will be sufficient. I
see them on Amazon in the mid $200 range.
I have one of these:

CHIWI Hi10 XR
2 in 1 Laptop with Stylus Pen, 10.1 Inch Touch Screen Tablet Pc,
6GB LPDDR4X 128G SSD, Turbo frequency 2.6GHz, 1920x1200 Resolution

which is a separate tablet and keyboard. The touchpad isn't all that good as
the reviews say, and I've not actually used it in tablet-only mode. It has
updated successfully to Win-11.

I guess you get what you pay for!

Why might you be logging peaks rather than power.
I'd like to record total channel power like HDSDR does, but peak power is all the SNR logger plugin will do.  Since one application is simply to compare signal strength over time, peak vs. total doesn't matter so long as it's consistent.

Bob NO6B 

It sounds like the SNR plugin is as broken as I expected. Good luck with it. I don't think your FFT approach will solve the issue properly; but, I could be wrong.

I'm using the SNR logger to log peak power of NBFM stations using an Airspy Mini.  However, the peak power is derived from the FFT spectrum, not the total channel power.  This is fine for CW signals, but when there is modulation on the NBFM signals the peak power drops because the width of emission exceeds the FFT bin size.  I have the FFT resolution set to 512, which is the lowest it can be set to.  The only way to get the FFT bin size large enough to adequately capture a NBFM signal is to disable decimation, which leaves me with only 12 bits of dynamic range.  In the crowded SoCal VHF/UHF RF environment I often find that I need a couple more bits of resolution to maintain decent sensitivity without occasional overloading, so I prefer to use a decimation of 16 or 32.  I could still effectively log NBFM channel power if I could further reduce the FFT resolution to, say 16.  At a decimation of 32, the bin size would be then 150 kHz / 16 = 9.38 kHz, just enough.  The FFT display would be kind of useless, but it would allow using the SNR logger to record channel power of wider emissions like NBFM, & my guess is that this would be very easy to implement since fewer resources would be needed to implement a smaller FFT.
