} I am getting a Yaesu Quadra amp to use with my IC-756PRO exciter. I know 
} they can be used together, and lots of guys are doing so. BUT - I have not 
} heard of anyone making up a band data interface to go between them to set 
} the quadra to the band the PRO is on automatically. It appears that most of 
} the guys let the quadra count the freq to set it up, and others set the 
} quadra manually.
} 
} It appears that a LM3914 in dot mode and a set of diodes in a matrix is 
} most of what is needed for a true band-data interface. Has anyone tried to 
} set this up?
