hmmm...sounds like someone needs to read up on how CTCSS works... If someone else on the channel is using the same tone, you will hear them. (And as someone mentioned, some decoders are better at rejecting adjacent tones then others.) If there is someone on the same tone, and they were there first, your only option is to change tones. I'm assuming you're on a commercial system (hence the 450-460 in the subject!) Frequency sharing is the norm there, and if there is someone else on the same frequency as you, you just have to learn to share. If it's a community repeater with several tones turned on, you'll just have to turn that tone off, and maybe pick another if there's a user there, and reprogram their radios.
