Leif:

Forgive me if I'm not aware of everything that is inside Linradio and you
already have something like the below.

I'd like to see you expand the scope of #4 to include splatter from any
source. For those of us that mostly DX the AM broadcasters, splatter is the
huge enemy. A solution that I'd like to see is a sort of Costas loop where:
(1) the signal is split into two paths where one is demodulated with an
in-phase carrier and the second with a 90 degree shifted carrier, (2) the
"Q" output is shifted an additional 90 degrees, and (3) the two demodulated
outputs are selectably added or substracted.
