Thanks very much for the info. As you guessed, I have a question about transmitting PL. There is a repeater pretty close to me that has PL code xxx.x, in and out. I set up the code for the repeater with the R and T code as CTCS, and the offset is preset in my radio (+5). I can't hear anything from the repeater. Should I have set R and T code as DCS instead? As an aside, on a GMRS channel the other night I heard some guys talking about repeaters, and one of the guys was in Tuscon! That made me wonder why I can't hear anything from my local repeater. Maybe the repeater is just quiet and I caught some weird radio inversion or something that allowed me to hear AZ from NC (haven't heard much since). Thanks!
