The issue here is a change in the level at which the hardware AGC begins to take effect. There is no "problem" - hardware AGC works as designed. However, HAGC may begin acting at a lower level than absolutely necessary to protect the DSP chip - the design was conservative. If you are following those parts of the discussion that field testers have allowed to slip in public, it may be possible to increase the HACG threshold and reduce the somewhat to reduce the "blocking" effect of strong signals inside the roofing filter but outside the DSP filter bandwidth without reducing the close spaced IMDDR. The radio is not defective - this is not a fix. This is an improvement that may not even be necessary if you are using "matched" roofing filters - roofing filters with bandwidth similar to the DSP filter. However, not every user will need or want to load the receiver with roofing filters. Optimizing the HAGC threshold will provide better performance in the unique situation of "unmatched" filter bandwidth. The K3 is not LINUX - it's not open source development and/or GPL.
