Hi all. total new person here. I see when I look up an open repeater on here it has an input tone and output tone. Could someone show me a screenshot of the CHIRP software of how/where the input and output tones would be in the chirp program if the tones were different? Also do you need to enter both if they are different if you are willing to hear everything and just want to make sure you can transmit to the repeater? I saw mixed reviews that some say don't enter one of them to be safe. Thanks
