We inspect each and every one of our radios thoroughly, Each radio is carefully tested for operability. We perform transmit and receive tests on each unit to ensure that they are properly functioning prior to listing. We do not sell "junk" radios or radios without factory tags. Large percentage use of the radios I sell go into public safety applications where people's lives depend on the user's ability to successfully transmit and receive in critical times. I encourage all persons using these radios for public safety or mission critical applications to have qualified communications expert evaluate the radio's operational status before use in the field.
