While their are some repeaters around here that have PL to keep out the "riff-raff," the only repeater that I generally use installed PL to stop interfering signals from unintentionally bringing up the repeater. This can either be due to another repeater on the same frequency, or as in this case, a cab company with a bunch of poorly maintained AEROTRON commecial radios. We allowed the repeater to be brought up using any one of the following three methods: 1. PL. 2. Any Touch Tone 3. Three kerchunks within one second followed by the carrier staying on. -Ron
