That is not how a repeater is used as your example in a pit or on a logging landing, the repeaters are used to transmit literally world wide. A pit operation or a logging landing would not go through a repeater to conduct their business/operation there would be no need to. There is a programming software for these radios and any other uhf/vhf. Also if you go on line you can see all the channels listed as well as the repeaters.
