In my area, we have two different repeaters owned by two different people approximately 30-40 miles apart. Both repeaters are on the same frequency but one has ctcss on transmit and receive and one has DCS on transmit and receive. When someone breaks the squelch on one channel from that channel, the audio from the adjacent channel will flow in also creating the effect of both channels talking at once until everyone lets off the mic. If no one keys up and the adjacent channel is talking you cannot hear them unless you switch to their channel. Confusing? Yes. It is for me to try to explain. Suggestions anyone?
