Just a couple simple hints here for best practices that I have found works best on voted systems.
You want to keep all of the receivers connected to the voter the same. You also want to keep all of the controllers and link radios at the remote sites the same. For example if your main repeater receiver is a Mastr II then all of you main receivers should be Mastr II. If you choose a Motorola Maxtrac for a link transmitter, then all of your link transmitters should be a Maxtrac. Setting up and balancing the audio is the toughest part of a voting system for most people. The goal is to not be able to tell if a user is coming in on one of the remote receivers or the main receiver. I know from your previous messages that you prefer the smt technology radios, but from a RF standpoint, most are not made nor suitable for for use in a repeater site environment unless you have pretty deep pockets. You will find that some of the Motorola mobiles will hold up just fine for the link radios, but for your main receivers and repeater transmitter it is very hard to beat a Micor or Mastr II repeater station (not a mobile) with a good preamp.
