Guys, we do plan to do more work on the DSP capabilities in SmartSDR. However, they won't be in the release due out July 31. If you want to vote specific features or improvements up, feel free to enter them as an idea and vote them up. We have to weigh these requests against road map commitments that we have already made public and intend to keep.
Noise Blanking is an area where direct sampling radios can shine because of the wide band sampling capabilities. That may require potentially significant work on the FPGA side so you will have to be patient.
With regard to Noise Reduction (NR), properly setting the AGC-T threshold for optimal signal to noise ratio will in my opinion always beat any NR algorithm ever created. NR algorithms use non-linear functions (LMS) to auto-correlate the desired signal. Given their adaptive non-linear nature, they will always color the desired signal in some way. Different types of noise will affect NR in different ways with varying results. On the other hand, setting the AGC-T gain properly will give you the best SNR without distorting or coloring the signal at all. My personal opinion is that NR will always be inferior to a properly adjusted AGC-T on any rig ever made.
