So I was given a cb radio the other day and thought I would ask some questions about it. It's a Regency cr-230 cb with 23 channels. From my research I understand that today that's all I need. While in my own time I will upgrade to something newer but this is a good start for me I think. My question is how reliable are most of these model radio? I know it was first made in 1977 or 1976 until 1980. This raises another question for me. Is my radio rare because of the required 40 channel production that started in 1977? Right now I don't even know if this thinks works because I don't yet have an antenna for it. I can only find limited info on this radio. It has a needle indicator instead of the more modern electronic display. I plan on testing the thing out next week using a friends setup. I'm only getting into this because there are a lot of dead zones in my area and I'm worried about my car breaking down in them. Also does anybody know if a 97 civic has enough ground plane for a cb?
