[TenTec] 2.063 Xg - AF Vs RF AGC

[G.C.]

Dear friends,

first of all I would understand better the differences between the two AGC systems and their capabilities.
Could anyone explain the different solutions and their features? 
Secondly, when I change between the two systems through the RX menu shortly when the DSP message disappear the system seems to work properly. Is this procedure correct?
Third, when AF AGC is chose the NR doesn't work and the radio is muted, is it correct?
Fourth, when RF AGC is chose the NR work properly and it seems better than the previously firmware version.
Fifth, what is the purpose of the MIC/PWR setting on the OTHER menu ?
Sixth, could we change the sweep windows bandwith ?

Thanks
