Thank you for coming to this page. Here you can submit the makes and models of the walkie-talkie two way radios that you use. The make and model will usually be on the front, back or side of the radio. I.E. Motorola DP1400 (Front), DP4800 (back toward the top), Hytera PD705 (on the side towards the bottom). On some handsets the information can be accessed by removing the battery. Thank you for youyr input. Your details will not be stored or used in anyway and will be erased after I have obtained the information about your radios.
