Automated diversity reception for noise cancellation/beamsteering/ESC

https://community.flexradio.com/discussion/comment/13563550 contained two feature requests, one for ear-driven 'noise filtering' and one for FPGA/computer-driven noise filtering based on dual-SCU capture and math (whether the PowerSDR-style phase cancellation Enhanced Signal Clarity, with e.g. a directional on TX/RX1 and an RX-only omni:
or more advanced/automated/... techniques

in place of external units, e.g. https://www.youtube.com/watch?v=4EJXHpANxYY

Ear-driven diversity reception has been implemented and that original idea was marked closed, but the automated approach does not appear to have been implemented.

    I've seen this comment a number of times and not been on the board for a good while. This was in the 5000 and worked killer. Was on the roadmap for the 6 series, but the car seems to have left the road and gone over a cliff, which is a big shame. Why have a capable radio and no implementation. Sense - no it doesn't make any at all. Noise is one of the biggest challenges facing ham radio. Have a look at the Anan doing this - video already linked by John above. I had the 8000 and it works as good as he shows, as it does on the 5000, which KE9NS is showing in the other video. Please can a moderator or someone explain why after all this time has this not been implemented?

    I too am disappointed in the non-progress of this capability. I bought 2 dual SCR 6700's early-on largely because of this anticipated feature. I doubt that they have any plans to implement even a manual version because a requirement would be to be able to assign an antenna to each ANT1/ANT2 and SCR. It has been stated in other posts that they cannot do this and keep SmartSDR the same for all versions of the 6000 series. Our loss.

    Bill, totally agree. My 6700 purchase, pre V1 ssdr, was entirely because of the 5000 noise processing and promise to have (**eventual**) support in 6000.

    Other features are unique between models and having active noise reduction (as per 5000) would be a reason to purchase the higher end 6000 series. For example currently 14Mhz panadapter width comes with the higher end A2D converter and sub 4K resolution for 6700 (now the newer models) are upper model features.

    Why not noise phasing? Perhaps the GateArray power, it was a PEN on the original 6700s.
