For a long time the Motorola GP300 was the no nonsense workhorse among the handhelds. With its rugged construction and either 8 or 16 channels it suited many purposes. Also in daily usage this radio was a favorite because it wasn’t too heavy, handy and produced a good and loud audio.
Most commonly used were the GP300 ‘PL types’. These radios (VHF as well as UHF) had only CTCSS (in Motorola language ‘Private Line’) on board, so no ZVEI (5) tone. The GP300 on the picture is a ZVEI-type. This can already be seen because it has a keypad, which the PL-types don’t have. Beside that this is a regular VHF GP300.
Programming the radio has to be done at the backside. An original programmer is clicked on the back of the radio, instead of the battery. The battery is than attached to the programmer again. But there are also quite cheap programmers with external power connections available which are attached to the back of the radio.
