Just a friendly heads up. When asking questions about repeaters don’t post specific info on the repeater unless you are in the private (members only) area of the forum. So maybe just don’t include the name of the repeater or leave out specific tones. Here’s the what and why per forum rules located here.
Private content. Do not post sensitive information such as repeater PL/DPL (also known as privacy or CTCSS/DCS tones) tones outside of the Private Discussion forum. This is to protect sensitive information from being picked up and indexed by search engines such as Google and Bing.
The N indicates Normal while an I would be for Inverted.
As you mentioned there is a +5 for Tx. It is worth noting that the +5 is automatically added on the preset repeater channels of GMRS radios and won’t require you to add it. You may know this already so I mean no disrespect by mentioning it, just trying to help. It sounds like you are on the right path.
