I agree with Moleculo - it definitely is something nice when trying different microphones or even in some cases I prefer to run gain lower for local and higher when shooting DX.
Opening the case every time isn't fun. RF gain to me is the same type of thing - I run it at 3/4 most of the time but sometimes I like to be able to open it up further or back it down.
Either way I think the echo is something you add at the end if you have room after allowing for all the true radio functions.
The Voyage 9000 comes to mind as a radio that lacked microphone gain and was annoying to operate (in addition to many other reasons).
It will definitely be interesting to compare this new radio against its competitors.
i'm finding it hard to understand why you'd want to reduce mike gain for local and run it full for dx,seeing as you don't benefit either way it seems pointless.unless of course you sit listening to your own audio via talkback.good audio is good audio regardless of distance.
the same applies for rf gain,why would you want to run at reduced sensitivity,unless you are being desensitised by front end overload from strong local stations.i find your reasoning very hard to understand.
