You cannot turn the Orion II AGC off.  I found this little tidbit of information
while trying to peak a noise generator on the Orion II here.  If you watch the
ac voltage on the phone jack or speaker you will see that it never changes with
the AGC OFF.  You will also notice that on an Orion II, when you set the AGC to
OFF the S-Meter still deflects with the signal, indicating that in fact, the AGC
is NOT turned off, it has merely been set to a decay rate of 1000 db per second.
Otherwise it functions as when in the other positions.

to obtain a little temporary safety
deserve neither liberty nor safety.
