A community repeater is shared by multiple users, each using a different PL/DPL code. If all users have decoding set up and the mic hung up, no one hears anyone else until the user goes off hook. The hardest part of operating a community repeater system is to educate all users that if someone else is talking they can't barge in and overpower the other user. LTR is so much nicer...
