Peter, I will take a stab at this and some of the others can jump in and help out also.
Yes, you are correct in your assumption as to how a community repeater works. It is a single channel repeater with the ability to have different user groups that each have their own PL or DPL Tone. The repeater can only handle one conversation or user group at a time. Typically the mobile radios had a wire connected to either the hang up button on the microphone or they used a hang-up box that contained a switch inside it. The way this worked was when the microphone was hung up in the holder, the radio was in PL mode and you could only hear conversations from your group. When the microphone was picked up or taken off hook to make a call, the radio was then changed to carrier squelch mode and you could hear if the repeater was in use by another group, or was available for use by you and your group. If it was busy, you just waited your turn and if it was clear, you were good to go. It was not uncommon to have 6-8 or more different user groups on a single community repeater.
