Does a simplex radio system allow many talk groups to share the same frequencies?

In a simplex radio system, communication occurs on a single frequency, allowing only one conversation at a time. This means that all users must take turns transmitting and receiving on that frequency. Since only one user can talk at a time, multiple talk groups cannot simultaneously share the same frequency without causing interference or confusion. Each talk group requires its own dedicated frequency or channel to communicate clearly without overlapping conversations. Thus, the statement that a simplex radio system allows many talk groups to share the same frequencies is false.
