I was writing software for radios in 1981. Diagrams might help understanding, but the source code is the equivalent to a schematic. We already have a block diagram for the KX3 and people keep complaining.

I think it is based on a Kalman filter with the “known signal” input generated from a lowpass-filtered or averaged version of the input. But I won’t figure that out from the block diagram. So, not useful to me. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Oct 5, 2016, at 6:20 PM, Matt Maguire <[email protected]> wrote: > > Source code is too low level to get a conceptual understanding of what the > software is doing -- a software architecture diagram is likely to be more > useful for that.
