The Wouxun S-Series of two way radios consists of five models encompassing four different radio services. These include Aviation, Business, CB, and GMRS. Each model is specifically made for the service on which it functions. All models are FCC type accepted to legally operate on the band, frequencies and service for which they are assigned.
While there are some standard features that are built-into the entire S-series by default, there are also some important differences. These differences are primarily due to the requirements and limitations imposed by the FCC on radios that operate on a specific service.
Below is a reference chart with a general overview of the differences and similarities between the current models in the Wouxun S-Series.
