I¡¯ve never heard of a radio receiver that is too sensitive! The easiest solution is to just turn the RF gain control down; it reduces the overall input from outside the radio. Then use the AF gain to increase the audio level of the signal in the radio. It may take a little juggling between the RF and AF gain controls for optimum sound, but you don¡¯t have to make any other complicated changes to your radio. That¡¯s why there is an RF gain control in your radio. This also works to reduce noise like Atmospheric or electrical since they are not AF signals. If you make any menu changes, you might have to change the RF/Squelch control from Squelch to RF

If someone is telling you the 857 is too sensitive to use with a 'base'
antenna, beware because they are definitely blowing smoke somewhere that
you really don't need smoke !! I would consider looking for advice from
another source.

Hi everybody,
I am using this radio at home, and I am being told that the Rx
sensitivity is too much for a base antenna, since this radio is
designed to operate mobile.
In fact I have TOO MUCH of a problem with the QRM, (never less than
9+10, in 80 m, never less than 8 at 20 m), so I thought that maybe
it's a good idea, if I write down all the current settings of the
hidden menu, and then reduce little by little the sensitivity in all
the bands. Just a tiny bit, just to have a quieter receiver.
I am NOT sure if the current settings are the original, cause I bought
it used, so before I do anything, I would like to have someone's
ORIGINAL SETTINGS and of course a guidance regarding the menu's items.
Thanks in advance,
Michael
