Try to use the highest level of RF gain setting (lowest level of gain reduction) that you can get away with without overload and it will help minimise the impact of this spur.

Hello John, The SNR measurement is only for the selected signal as defined by the filter bandwidth defined within the Rx Control panel. The signal power is taken from the power meter measurement and the noise is estimated via an analysis of the entire wider band noise floor within the SP1 window to ...

The S-meter in SDRuno is correctly calibrated to IARU standards and maintains accuracy across the full range. The same is not true for many other items of communications equipment. The only requirement for any adjustment is to allow for external amplification or loss.

Have you tried a different card? It may be that you have a bad SD card.

When you first start SDRuno, the VFO and LO frequency will be the same. You need to click on the SP1 spectrum display with the mouse to create a separation between the LO and the VFO. Once you have done this, the LO will track the VFO with whatever offset you have established maintained, unless you ...

There is a bug on 1.22 in some of the sub modes of FM I am afraid. It resets the step size to 100 kHz. It only does this in FM mode. It will be fixed in 1.23. You change the step size by right clicking with your mouse over the frequency display in the Rx Control panel. You can then select the step s...

Hello Mark, Check what frequency step you have set. It sounds like it might be set to 50 kHz. You cannot select a change in frequency of less than the frequency step size when clicking with the mouse. You can however scroll the frequency by any decade step from 1 Hz upwards by simply hovering your m...

Hello Ray, We cannot replicate this and there has been no changes in SDRuno in release 1.22 that relate to this aspect of the code. The message that you are getting is caused by the API communicating back to SDRuno that SDRuno has requested an illegal frequency for the RSP, so it is purely a softwar...

Hello Jesús, If you are only getting a maximum bandwidth of 2 MHz then you have probably selected low IF mode instead of Zero IF mode. Please open up the Settings for the Main Panel and check that you have Zero IF mode selected. 2 MHz is the maximum available bandwidth in Low IF mode. Sincerely SDRp...

Hello Koyel,
Your question appears to be gnuradio specific as opposed to RSP related. Hopefully someone will be able to help you, but you might get more focussed help via gnuradio.org
