If you are using the on board Intel video in the Dell then you can install an Nvidia graphics card and SDR Console will utilize the CUDA cores on the GPU to reduce CPU load.

Re: Minimizing CPU load
Curt Faulk
Are you running the latest version? Have you checked?
3.1 is actually very light on CPU usage. Mine is often 2% maybe 4%. 3.1, March 18th, 2022, Build 2547 is the latest.

Minimizing CPU load
n6vl
I've been trying out Ham Radio Deluxe Logbook recently and noticed it can be quite sluggish. Traced the problem down to SDR Console itself. It seems like running SDR Console is enough significantly slow down HRD Logbook and also Log4OM as well. I absolutely prefer SDR Console over SDRUno. My hardware is SDRPlay Duo. SDRUno does NOT degrade the logbook software performance, but it's NOT my preferred panadapter software. My rig is a Yaesu FTDX3000. My PC is a Dell OptiPlex with an i7 quad core and 16 GB RAM.

Re: Continuum mode

If sampled with 2. 688 in pluto also downscale to anything smaller Be it 500 kc (transponder bw) Down to 1hz (or calculated /referenced down to that fine resolution) Could be very useful to measure channel power etc Am 19.03.2022 20:24 schrieb sm6fhz <ingolf.fhz@...>:

Re: Continuum mode

Hi.
I took the liberty to collect the specification points we have been throwing around here in this thread for a week or so, in one bulleted list. I hope it makes it easier to have all of them in one place. I also added a few new ones that I came to think about at the end.
Save on time and effort. The programmer needs to get a lesser work load :-) When a Beta is available I am ready to and more than happy to start making tests. 73 / Ingolf, SM6FHZ

Great news, Simon, and glad that Moe was able to help. He must have
a better memory, or more organized files than I ever had.

It would be wonderful if you could document the algorithm that you will use for your realization of the continuum function, even in the most basic fashion, for those who are curious about what goes on behind the curtain. Nick At 16:04 2022-03-19, Simon Brown wrote:

Hi Conrad,
Thanks for sharing that. I also have one on order. Some rumors have been circulating around hinting that it might be delayed. I am sure they will get it figured out.

Re: K4 and SDR-Console
Fred
Conrad,
Thank you I figured this question would come up. The K4 does have a beautiful display and I do use it. I have a video capture card and route the HDMI port on the K4 to my PC and then can use Windows camera app to view the K4 screen. And that works great I can move the window around resize it full screen etc. But it's nice to have options and I use the SDR-Console memories. I switch back and forth. And I like SDR-Console look to. I also use SDRUno to. And probably a little of old habits die hard to. I'm playing around now in the BARTG RTTY contest today and the K4 waterfall band scope and also the Mini-pan are great for FSK rtty. Thanks 73 Fred KB4QZH

Re: K4 and SDR-Console
Conrad, PA5Y
Hello Fred.
I must ask why you use an RSP2Pro and SDRC when you already have an SDR based radio with a waterfall? Surely the K4 has a much better receiver. Is the K4 waterfall poor?
I use SDRC as a band-scope with my TS-890S and K3S in conjunction with a Perseus because it knocks spots off the TS-890S waterfall and of course the K3S does not have this facility. Is it the same with the K4?

K4 and SDR-Console
Fred
Anyone using the Elecraft K4 with SDR-Consloe?
I'm have a small problem. When I have SDR-Console running then I start the K4 up it puts the K4 into transmit for a few seconds. When I start the K4 first then start SDR-Console this doesn't happen. Any have any thoughts on why this happens? And yes I know one answer is "just don't start SDR-Console first". I am using SDRPlay RSP2Pro. Thanks 73 Fred KB4QZH

I've just played back a NetSDR file in Continuum mode, 1300kHz span of the MW band, using 2048 point FFT and 2097152 point FFTs. Except that the 2048 point playback zips by very quickly (unsurprisingly), it jitters around -32 dBm, while the 2097152 point playback is more sedate in speed, and with very little change in the -32 dBm value, again unsurprisingly. The "jitter" is presumably real, as the power level of individual signals in the night-time MW band is constantly changing. If the commenting in SpectraVue's code is anything like what was in Moe's SDR14xApp, and CuteSDR, he probably tells you what he's doing right there. Finding it might be another thing.

Hello Simon, I really appreciate you adding this feature. I do have SpectraVue and an SDR-IP and in the past like Charles I used SDRC with Perseus and the IQ outputs as inputs for SpectraVue. Very cumbersome!
Let’s get it working and then I have some other ideas.
This will be really useful.

Hi,
That’s fine. I can get almost all work done, then there’s fine tuning. I think a docking window like the Signal History is the correct solution.

Re: Continuum mode
jdow
Figure one signal is present, a unit gain (0 dBfs)
sinewave. Without shaping it will appear in one or two bins
ideally. You take the power level for all bins within the
bandwidth Y and sum their power, not voltage, of course. It's
independent of the X bandwidth. Scaling would be the same as you
use for the spectrum display.
toggle quoted messageShow quoted text
Or take the FFT array of values, multiply each cell by your calculated IF filter shape, pick a bundle of values around the center of the filter to get a nice power of two bin count, take reverse FFT, pseudo power = I^2 + Q^2, Nominally ir should have scaling to make that come out as 0 dBfs for that single sinewave signal. Then the real world should sort of fall out of what you have with no further work. (Yes, I am fixated on I^2 + Q^2 pseudo power.) {O.-} On 20220317 03:45:40, Simon Brown
