         Sinisa, there are TWO AGC's in Orion.  One is
Analog AGC which CANNOT be turned off since it is
ALWAYS ON to protect overdriving the DSP's ADC with
signals stronger than ~S9+30.  The front panel AGC
controls the Digital AGC within the DSP which may
be indeed be turned OFF.  If you want to learn more
about Orion's dual AGC's, read this article:
