This site is dedicated to AM/FM radios that function well in Heavy Metal Bar facilities using Internal FM Transmission Systems as well as normal FM Transmission.
We boxed the radios for easy unpacking. No need to cut them out of a blister pack. Our radios use AAA batteries. We also carry a variety of Earbuds. Normal shipping time is 5-7 days from receipt of order.
