I have no option to turn off AGC with the FT-736R.  I had been running 
on the Medium setting (my default) and have switched to Slow now.  I'm 
not sure to say because it's rather subjective just watching, but I 
think it has slightly improved capture especially at AOS and LOS as well 
as when I have de-sensing due to my other VHF stations so rudely 
beaconing their APRS and WL2K info without regard to the science going 
on!  ;-)
