Hello Jim,

The audio level going to RITTY shouldn't have much affect on weak signal
performance as long as you keep the level at a reasonable level.  You can
use the RITTY's input level adjust instead of a seperate external input
audio control.  This is one of the settings you should make before running
RITTY with WL.
