Call me dense, but I'm not understanding why one would expect that
turning AGC off would NOT result in a huge jump in AF output.
AGC turns down RX gain - a lot. The only time there should be no change
in AF output is when the RF input is so low that it hasn't reached the
AGC threshold.
Maybe other manufactures have coupled AGC on/off with AF attenuation, so
if the AGC is off, AF output is automatically reduced by 20 dB or
something.
For this very reason, I always run with AGC on. Even when I want the
rig to act like it's off, I leave it on, set to Fast and then just turn
the RF gain down to put my signal of interest down near the point where
AGC is doing very little. AGC is still on to protect me in case some
big signal QRM or QRN shows up.
