So I just received my license earlier this week. I'm still trying to figure things out. I bought my first GMRS radio Wouxun 805G. I plan on buying another radio GMRS radio this weekend. I will be using my radio to communicate with friends and family. My radio looks to be pre-programmed for the GMRS frequencies. I see there is one repeater in the Twin Cities called Metro 4. Do you have to request access to use this repeater? When you use the repeater can anyone hear your conversations? I notice the radio has CTCSS and DCS codes. What do those mean? Sorry for all the questions. My first time getting into GMRS. Have a few friends that are HAM operators and hope to study for that soon. :-)
