Separate audio and digital receiver modes into separate sub-menus.
Reworked baseband DSP filtering should improve receiver sensitivity.
Narrowband and wideband FM audio de-emphasis improves sound quality.
Debug views for clock generator, second IF, and audio codec.
Architectural and code improvements, reduction in baseband code size.

Spectrum waterfall update/repaint artifacts at bottom of display due to timing vs. screen refresh.
