Hi Ken, We don't have any GMRS repeaters around here, but I don't set a specific receive CTCSS for the repeaters I use in Ham radio. I hope to put up a GMRS repeater for our community sometime.

The repeater requires a tone to 'open' the repeater, and the receiver is silenced until it 'hears' a signal with the proper ctcss tone. With the wrong tone on transmit, the repeater will not rebroadcast the signal, it will be ignored. If the receiver has the wrong tone set in its receiver and the receiver is programmed to only break squelch when the proper tone is heard, the user will hear nothing. The tone squelch function is optional, it can be turned off, and the receiver will 'hear' any RF signal that is strong enough to break squelch. The above is true for most commercial FM repeaters, as well as amateur repeaters. It may be different in the GMRS user space, but I doubt it. If there is a doubt about any particular repeater 'passing' the ctcss tone on transmit, the user can set their radio to only transmit the required tone, and to not have any output tone from the repeater. On a Baofeng that would mean setting signaling to 'tone' and not 'tonesq' (I think, from memory).
