Automatic Gain Control (AGC) settings in FT-710 amateur radio

Automatic gain control is meant for controlling wide fluctuations in audio levels while listening to stations with widely varying signal strengths, as is common in amateur radio. Here is a demo of changing the different settings of AGC in FT-710 amateur radio. Four options are there: Auto, Fast, Mid and Slow. In addition, I am also demonstrating the effect of digital noise reduction (DNR) which has been set at a level of 5.
