Last version of SDR Console v3.3 Beta build 2993 June 7'th 2023 is published:
https://www.sdr-radio.com/download (https://www.sdr-radio.com/download)
After installation, the work is trouble-free. Works stably on RX 888 under Win 10/64.
Important to me - Many fixes have been made to previous versions.
The program now starts sensationally in 10 seconds instead of the previous 1 minute of loading.
Important for me is the active operation of the Noise Blanker Wideband DSP, placed on the Home ribbon. Threshould deep cut introduces audio distortion - do it gently.
I still miss the point Noise Filters like in the HDSDR program.
Noise reduction and Noise Blanker placed in the DSP panel does not work with AM modes.

Hi Kris,
Important for me is the active operation of the Noise Blanker Wideband DSP, placed on the Home ribbon. Threshould deep cut introduces audio distortion - do it gently.
SDRuno has the same effect when the Noise Blanker level is set too deep. I find that the DSP also destroy some of the digital modes as it thinks it is noise. It is a compromise but the feature does work very well for me. You just need to know when to turn it on or off.

Here are examples of how it works:

Terrible broadband interference without turning on Noise Blanker

Moderate level of attenuation does not cause audio distortion

Deep attenuation removes the interference completely, but deforms the audio
I'm looking for settings in the hope of improving readability.
The QRM Phase Eliminator (external) works less radically, but the interaction of both methods usually allows you to get a clear signal even in hopeless conditions!
The disturbances shown above start around 7 am and last until the night. I think they are emitted by a photovoltaic installation that a neighbor launched this spring.
And it was quiet here with noise level S2! :-\ :-X :'(
Today Jul.22 - The receiver (in 4MHz bandwidth) worked today without a break for many hours in the HF, VHF and UHF bands and there was no suspension of Consola!
Compared to the previous version, the CPU load is noticeably lower and 8GB of memory is apparently sufficient.

To update this, Beta Version 3.3 Build 3048 became available on 1 August. This version includes an AI-based noise reduction (NR5) that's worth the price of admission. OK, it's free.

Thanks Mike for the news about the new NR5 filter. It works effectively but only in SSB modulation. Unfortunately, the AM and SAM modulations that are important to me are still devoid of noise reduction.
I'm disappointed with this and I'm waiting for an effective solution!
I deal with difficult interference by turning on the ECSS-U/L decoder, but the audio distortion is unpleasant.
