I've found most repeater owners to be quite receptive to gain access. Just take the time to request access or email them and you'll generally get a prompt response. If you get no response, chances are the repeater is no longer live. I have the MXT-275 which is basically the same radio as yours sans the controls on the mic. 

Thanks for your feedback!

After obtaining my GMRS license earlier this year, I finally broke down and ordered the Midland MXT115 that just arrived yesterday. 
 
I put it in my vehicle this morning just to give it a checkout. There is a GMRS repeater within 2 miles of my residence and thought I'd try making a contact however I can't get the radio to go in to "Repeater" mode.
 
The instructions in the manual are fairly straight forward and I've followed them step-by-step however I cannot get the desired sub "rP" to appear on the display, nor will it transmit in duplex mode on the repeater channels. 
 
Before I call Midland tech support can anyone suggest a hint or possibly a step that isn't in the instruction manual?

I would love to use chirp but too many issues trying to work this on my macbook( big sur).  

It will be easier to use channel mode instead
For example:
Say your repeater is on 462.600
Arrow to REPT17
Say the CTCSS on both input & output is 100.0
Press Menu, then up arrow until you see R-CTCS OFF,
press menu again, up arrow until you see 100.0 HZ, press menu to confirm
Up arrow to T-CTCS OFF, press menu again, up arrow until you see 100.0 HZ, press menu to confirm
 
You should now be set up to use the repeater
The radio will automatically know the receive & transmit frequencies
and you have manually entered the CTCS tones
 
If the the repeater uses split different tones for input & output, the steps are the same, 
just select the tones that you need

Thank You!
