Is there a scenario in which moving the slider from the middle position is helpful? If the audio coming in is too hot, then moving the slider will make the number lower but it won't fix clipping. As you point out, only changing the analog part of the chain will prevent that. -- mike NF4E ------------------------------------------------------------------------------ _______________________________________________ wsjt-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/wsjt-devel
