Yes, I would rather hear anything else coming in on the repeater's transmit frequency, in case someone does not have a radio set up right.

You never HAVE TO set an RX tone, you can choose to control what you hear by simply setting the radio RF Squelch to suppress static between transmissions.
I see 4x repeaters near your license location, W0OFK 146.730 And KG0S 444.125 both transmit tones on their output, while W0OFK 444.250 and K0RPT 146.880 do not transmit tones.
The above is from RepeaterBook, one of the data sources integrated into CHIRP.
Using an RX tone/signaling setting is optional, not required.

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.

Glen,
I disagree, many, many repeaters that use cut SS tone 'pass' the incoming tone to the output, so that users only hear silence until their repeater transmits another users signal.
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).

Usually repeaters don't send out a CTCSS tone, they only use one to make sure it only hears signals that contain a CTCSS tone. Thus, the 88.5 should be fine for the rFreq, but you will need to send a tone to open the ears of the repeater. Glenn
