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 ...

Re: SDRUno Recording - Bandwidth and Timer Function

The recording spectrum is determined by the sample rate and decimation you've selected in the Main window, it's the same as "Final SR". The recorder seems to simply write the post-decimation data stream as a WAV file - there are no supplemental sampling controls in the Recorder function. Y...

Re: Record fails with "Unable to create a new output WAV file"

Check your setup. First thing I'd look for is whether the folder path you've specified actually still exists. Does your target drive have enough free space. Creating the WAV file may require Windows to reserve disc space & you don't have enough the process will fail. This happens if your target ...

Re: Erratic RF Gain control

Actually, I've developed an SDRUno user guide, albeit incomplete, that's available from my Dropbox: https://www.dropbox.com/sh/nz5t2x9ge8td1o2/AACv0z1hKxSJJo6v0OWKg3-pa?dl=0 I've posted this link in the "new users" forum as well. It's in LibreOffice Calc .ods format. As mentioned, it is in...
