Sorry if I'm replicating an older post (I've searched and haven't found anything similar so here goes).
I've been throwing around ideas in my head to get voting at our TRBO site short of having to buy several other XPR8400s or MTR3000s just to use as receivers which is cost prohibitive for our operation. This is a Ham site so we have some leeway to experiment.
Has anyone put some thought into or have tried the following?:
I'm thinking of setting up a voting system separate from the repeater that would pass digital signals transparently end-to-end. The input side of this system would be the desired repeater INPUT frequency. And the output side would be a link back to the repeater with the repeater itself being set to receive on the link frequency and of course, transmit on the desired OUTPUT frequency.
Example:
RX 443.000 / TX 448.000
INPUT: Receiver (443.000) / Link Radio (902.000) --------[link]------> Link Radio (902.000) / Voter / Link Radio (430.000) -------[link]-----> Repeater (IN 430.000 / OUT 448.000) :OUTPUT
Also, does anyone know how the receive radio in the XPR repeaters communicates with the controller? Is it just a dumb receiver passing audio to the controller, or is there processing, etc that is done in the receiver before it is passed to the controller? If the receiver is just passing a generic signal, I wonder if it might be possible to remove the receiver and somehow connect the voter directly to the controller.
It goes without saying, that for anyone familiar with cheap MaxTrac P25 repeaters this would of course be a compromise, but its the only way I can see that would pass talkgroups, IDs, etc intact. And of course, there are times where tying up the repeater with a horrible signal is WORSE than not getting in at all so this all may be moot if signal quality across the system turns out to be horrible. Plus there's the issue of getting an analog voter to vote on a digital signal.
