This lag condition previously comes and goes, and eventually fixes itself, but not now. When tuning using the mouse wheel, there's a pronounced tuning lag of about 1 second from the time the frequency is changed, to the SDR actually tuning to the new frequency. Note that the tuning display numbers change instantly, so this isn't a situation where the mouse is also lagging or SDRC is slow to respond. I've tested this on both my RSP1A and RTL-SDR's. I'm running v3.0.23, but also tried this on version v.12 and .13. I rebooted the PC twice. Also tried the RSP1A on both the USB 2 and 3 ports with no difference.

It's as though it's a Win10 issue, but I don't see anything in Task Manager that seems out of the ordinary. My PC is running an i7-4790 and a GTX-950, with 16GB of RAM, so it shouldn't be a PC hardware issue. As I said, I've seen this on previous versions, but the lag condition eventually went away. Note the CPU at 13.5%, GPU at 1.2% and the Audio at 36ms.

Any suggestions would be appreciated.

in settings you can boost priority of console one step ... (did you try that already??)

lower bandwidth from the sdr (why use 2 megs bw if you wanna receive only 20m ham band??)

lower spectrum resolution (i guess you have set it to x4 or x8?!?)

lower waterfall speed (default is 40 but 20 lines per second is enough)

close not needed boxes (example the spectrum view below volume slider)

all those things lower cpu load and then reaction on user tune is faster

you have a superfast cpu and an additional graphic card running in parallel for sdr console ... i only have an old core2duo laptop and an atom tablet ... on both i have lower cpu load as you have on your low end gamers pc (compared to my setup it is super high ended ... but gamers use even faster machines)

for a fast working console try to lower cpu load as much as you can and then it runs superfast (it does on my snail pcs so it should even run faster on yours)

simon has a delay inside console when tuning ... yes (so i have to turn the midi wheel slowly for finetune) ... but one second?? ... no that is a bit long

so try with a bit lower settings (screen resolution etc) and then try again

OK,

 

There’s nothing in W10 which could possibly do this. If the RTL is fine and the RSP1A isn’t then I have no idea, it isn’t software / W10-releated.

 

BTW – I’m a fan of W10.

Before I change settings that I know work in SDRC, I opened up HD-SDR, and this same lag condition also exists. You change frequency, which it does instantly as seen in the frequency display, but there's about a one second delay for the SDR (LO?) to catch up. This is most easily seen and heard when in any SSB mode, then trying to off tune a signal.

From what I see, this is a Windows 10 issue (did I mention how much I hate Win10!). I haven't been using SDR that regularly, but I do recall a recent update, which may be the problem. In a futile attempt, I brought up Task Manager, and while tuning, tried to observe the CPU usage when rotating the mouse wheel, which didn't reveal anything obvious.

Hi Bill

Just to confirm I don't feel it should be an issue with SDRC running on W10, I don't see any lag at all. I even checked it before writing this to make sure I have not subconsciously bypassed it, but no..... tuning a CW signal I can hear only instantaneous frequency changes in SDRC when stepping frequency with the cursor/arrow keys on my keyboard (my preferred tuning method). Just for reference I also have latest 3.0.23.

I think you may have something running in your system that is soaking proc time? I admit it can be extremely frustrating when it's not possible to track down the source of a problem in Windows..... had plenty of those, but like Simon I am generally a big fan of W10. Think it is the best MS has managed so far by a country mile. Having said that, the boot time is a right royal pain. If you have ever owned a Chnromebook you will know what I mean.... instant boot!

Good luck and 73

Hi Max,

OK, here's a twist for you. Just for S&G's, I fired up SDR Uno (running the latest version 1.33), and it does NOT have the tuning lag seen in SDRC or HD-SDR using the RSP1a. No worries though, I'll never use Uno, as SDRC is the only SDR software of any capability and functionality.

I'm at my wits end on this. I'm fairly convinced it's not an issue with SDRC. I even tried V.3.0.12/13 again and still the same issue. I also uninstalled SDR Uno and installed V.1.32 (older version) and still no difference. Other than Win10 updates, there really hasn't been any other changes to my system.

As a last resort, I installed SDRC v.3.0.23 (and SDR Uno 1.33, just to get the correct drivers) on my HP i7 16GB (with integrated NVIDIA GPU), Win10 Pro laptop, and unlike my desktop, SDRC does NOT have the tuning lag. Note that these two SDR programs are the first on this laptop. As far as I know, both Win10 machines are the same versions with current updates.

Any suggestions would be greatly appreciated.

Thanks,
Bill

P.S. When I said I "hated" Win10, that may have been a bit too harsh. I should have said, that I have a real dislike of the UI, using Classic Shell, to rid myself if all the blotted menus and animation, etc. This also seems to have a lot more processes running than Win7 Pro did (I still have a PC running it), and also MS has locked down update options that I may or may not want, giving me no choice. But, all this is for a different time.

Simon,

Are there some configuration or log files that would show the differences between the desktop and the laptop, that would tell you how each is functioning? Perhaps there's a wrong driver, dll, etc. that's buggering up the works.

something you could try ...

close all not needed boxes (if display, spectrum view in rx and tx box etc ... )

lower waterfall speed

lower resolution to default (maybe you have it set to x4 or x8??)

then after setting all that ... a fresh start ... now a bit faster??

all that lowers cpu load (and only cpu load is what causes that tuning lag)
