āTransmissions that do not have the correct tone are not heardāā¦by you, the person that has the tone activated. You cannot transmit a message that canāt be heard by other people. A privacy code on your radio set to channel 1 squelch 142 forced your radio to ignore all transmissions on channel 1 that are not coded with tone 142. Anyone else on channel 1 with 0 code selected can hear all transmissions on that channel.Not correct, per Midland "Transmissions that do not have the correct tone are not heard." It's channel and code (142 of them) the code create the privacy. However the point is to have uninterrupted communication. I don't care who hears what I am saying. If someone is using the privacy code (tone) and same chanel in the same 50 miles or so, yes they can communicate and hear. But really when will that happen, and you can always hange channels or codes.

āIn other words, squelch just tells your radio what to listen for, it has nothing to do with what is transmitted.
You can test this out for yourself if you have two FRS/GMRS radios. Set them both to the same channel, and then set one of them to use privacy code 5. Turn off the privacy code, or set it to 0, on the other radio. When you transmit on the radio with privacy code 5, you will still be able to hear the transmission on the radio with the privacy codes off. But when you transmit on the radio with the privacy codes off, the radio set to privacy code 5 won't be able to hear. It's not that the transmission wasn't sent, it's just that the radio is ignoring all transmissions without privacy code 5.ā
