Sam,

Transmitter steering uses voted receivers to choose the best (single)
transmitter. Here is a good explanation:

Yes, this is what I mean. You are right that this is not a typical ham
application. The primary use of our repeater is in support of search
and rescue. Usually, everyone participating in the search will be in
the same general area, and therefore only the nearest receiver and
transmitter site need be used. It would be advantageous to reuse the
same repeater pair at every site, and the same tone, so users don't
have to figure out which repeater is best. Currently, our transmitters
do not have a timing reference input, nor do we have a fleet of
GPSDOs. Simulcast may be a stage two plan, but at this point I'm
looking at transmitter steering, since it will satisfy 99% of our use
case.
