Hey all, I'm a complete newbie when it comes to radios. I'm trying to make a channel for a specific repeater. I have the TX and RX frequencies, but it would only receive, not transmit. I'm using chirp, and i'm unsure what to put in the "Tone Mode", "Duplex", and "Offset" categories on chirp, and which ones I don't even need to bother with. Thanks!
