Hello Bill!

Yes.  Just press DISPLAY so the message DSP BYP is shown, then tap the BAND+
button.  The DSP will then re-activate at the last-used AFIL setting for the
present mode.  See pages 28 and 29 in the manual for a detailed example.

The AGC loop occurs completely ahead of the DSP module.  The AGC system has
its own 150 kHz IF amp and detector.  I don't understand how there can be an
effect on the AGC system by the DSP...
