This is the Dynascan Cobra CAM 89 base station. It looks like a Cobra 139, but doesn’t have SSB (single sideband.) Basically, it’s a Cobra 29 with the addition of a built-in power supply. That’s not a bad thing since the 29 was a great performer. When 40 channel CB radios became legal in 1977, the CAM 89 was upgraded from 23 to 40 channels and became the Cobra 89XLR.
