For others that may be reading this thread, the following was shared with us about the proper way to use the Attenuator/PreAmp slider;
============

I recommend that you refer to this article on how the RF preamp works in our radios.  In summary, if the antenna is not noise limited, increasing the RF preamp gain will decrease the noise floor while the signal strength stays the same which improves your signal to noise ratio (SNR).

Of course, other posters already mentioned the proper procedure for using AGC-T threshold also.
