4 Motorola Gp340 Ex intrinsically safe radios with charger bases but no power supplies although it takes a standard 12 volt power supply These radios were used by the fire brigade of the Atomic Research Institute at Aldermaston only retired because they went digital batteries are great and that’s the truth They all work back to back on 403.025 MHz and the overall condition is great These radios are specially sealed for use in dangerous environments like explosive atmospheres, probably why the Nuclear Fire Brigade used them
