This is a Hy-Gain Hy-Range I. It was the entry-level model in Hy-Gain’s mobile CB line. A very simple radio that was easy to use with decent receive and transmit capabilities. Power/volume, squelch, and a small meter. Because it was relatively inexpensive, the Hy-Range 1 was a popular choice for those getting started in CB radio during the mid-1970s.
