Excessive CPU usage

Hello all, I've recently run into a problem on a HP Elitebook 8440 laptop where trying to run SDRUno is essentially useless because of all CPUs pegging to 100%. The culprit appears to be the Windows audiodg.exe service hogging the CPUs and it's also affecting other audio processing applications inst...

Re: Minimize all problems

Thanks for raising the priority on this bug for the next release. If by "bringing windows to the front is syncronised" you mean that all minimised windows should reappear when restoring MAIN (or any other minimised window), it doesn't. The behaviour is as if the MA control has no effect.

Re: Only half of SP1 spectrum displayed

Found it ! In Main-OPT-Mode, I had the selection set to "Right Channel". Set it to "I/Q" and things are back to normal. So the answer is "finger problem" on my part when I was setting all the SDRU options to where I want them. Thanks to everyone who gave consideration t...

Re: Only half of SP1 spectrum displayed

Capture.jpg I'm using VRX0 to tune the LO, VRX1 to tune the VFO & do the things I want. I can tune VRX1 below 147.000 and (I think) it is demodulating ok, but the display won't go below 147.000. The zoom factor is at max, i.e. I've clicked the zoom left arrow until the display stops widening. Z...

Only half of SP1 spectrum displayed

Hello all; I've just installed SDRUno on an HP Elitepro laptop Win7Pro/corei5 working with SDRPlay 2 Pro and all works fine EXCEPT the SP1 window only displays the spectrum from Flo to Flo+BW/2. It does not show the spectrum below the LO frequency no matter how I try to adjust the frequency scale zo...

Tuner IF AGC Setpoint

Would someone please explain what "Tuner IF AGC Setpoint" does or mean in the Main-CAL window? Changing the value doesn't have any obvious effect.

Re: How to change the LO frequency

I've found that having two RX windows open is more effective for independent control of the LO and VFO. Leveraging off the fact that RX-00 is the only one that can control the LO, I have that RX open solely for moving the LO frequency. The second window is RX-01 which is used for VFO tuning and sign...

Re: SDRConsole and SDRplay

The resultant frequencies always being rounded to the nearest 0.1 looks suspicious to me. I don't use SDRConsole, however SDRUno has a feature that defines the frequency tuning step and the output frequency will snap to the nearest frequency with respect to the tuning step size. I wonder if SDRC has...

Re: IF GAIN

A significant disadvantage in disabling IF AGC is exposing vulnerability to overdriving the ADC which leads to nasty things like images, intermodulation products and possibly de-sensing signals of interest. I think the overdrive warning flag doesn't work if you disable IF AGC, so you won't know the ...
