I think that the K6XX interface is appropriate. I suggest

   } 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?
