TL;DR Midland MXT575 not Transmitting on GMRS Channels. Need help fixing this issue. I am brand new to GMRS radios. And for my vehicle I purchased the Midland MXT575, installed it with the supplied items. Power line directly to battery and ground. Use the magnetic mount with the MXTA26. I have gone over the manual, only made changes to turning rB(rogger beep) off and change the background color to orangeish. Everything else is set to default. Also obtained my GMRS license. I made my first transmission and thought no one heard me because I assumed I was stepping over other transmissions. Turns out my radio is receiving transmissions just fine. On Channels 1-7 I can transmit without issue. But on GMRS channels (15-22) the TX, Signal Strength, and Red light indicators come on but no one hears me. What did I do wrong in this setup? I have looked at the forms here but no luck. If I am missing any needed information please let me know. I have a feeling I have wasted money into this setup.

I have been around repeaters for most of my adult life but all I had to do was push the talk button on the mike and listen to the speaker in my Sheriff's vehicle. Things have changed. I have a Midland MXT275 and have turned on my Repeater Mode for channel 17 to reach a certain repeater's frequency. The Repeater has a listed output of 462.600mhz with 141.3HZ and a listed input of 467.600mhz with 141.3HZ. I put these CTS codes of 141.3 into my lower channel 17 (frequency 462.600) and my upper Repeater frequency channel 17 (467.600). My Midland Radio CTS number for 141.3HZ is 22: not a problem. My radio indicates all are input. But here is my rookie question so I don't make a mess out in the field. Do I transmit and receive on the same Repeater channel 17 or do I have to scan back and forth between the input and output channel 17 of the repeater. I even think maybe I have to utilize the Monitor mode of the radio to transmit and receive the repeater on the same channel. I just can't find reference in my instructions. Appreciate some guidance. Thanks Ole' Timers!
