The voter doesn't require an external controller. It's just very nice to have one. There is enough logic and control present on the rear panel of the LDG Voter that one could easily setup a hierarchy. > A new LDG voter lists for $319 and still requires a > separate controller.

Good point, a choice would have to be made... are all the repeaters going to remain tied into one operation? ... or will the repeaters be operated autonomous and require separate audio and logic bus. > An SCOM 7330 is a controller with three receiver ports > for $459, can be set to give each receiver a predetermined > (and remotely modifiable) priority independent of S/N ratio, > and would allow the three repeaters to operate independently > or linked in any combination. Or a single port repeater controller can be used with boxes like the CAT Auto RBS-1000B unit. > Don't get me wrong, I've drawn up some real kluges in my > day, but a voter as an audio mixer seems odd even to me. > 73, > Paul, AE4KR Not if the repeater is a constant multiple band, multiple repeater set up. It would allow an older single port repeater controller to do much more. If you need independent operation then some type of a matrix switch will have to be used and those are mostly inside some of the newer repeater controllers. cheers, s. > ----- Original Message ----- > From: skipp025 > To: [email protected] > Sent: Monday, January 04, 2010 2:17 AM > Subject: [Repeater-Builder] Re: Audio Mixer for multiple repeaters > > > > > > Each of the repeater receivers would provide audio and > a cor logic to one of the eight LDG Voter inputs.
