Yep, that’s correct. The offset is already programmed in the repeater channels. All you have to do is input the TX tone. I wouldn’t put a RX one in yet. Once you confirm. Then you can add RX. I never use RX tones. Well, I haven’t had to yet at least. Also, if you’re inside your house. Try it outside too. Just to see. Luckily I can hit most of mine in the area from inside my place. Even standing next to windows works wonders. No problem at all. Glad to help.
