Is this a box for switching microphones or switching radios?  I always 
wanted a switch box or a box with function buttons on it, but I just 
can't build that sort of thing.  You are right, voices and radios are 
different.  The eq stuff talks reasonably well on the 590 control 
program, but not at all on the 990  program.  THe microphone, that is 
the one we're discussing, does have a level pot and does not require 
batteries when run on the Kenwood radios.
