SEM 52 A






  SEM 52-A

is a German handheld radio of low power with six channels. It was developed to replace the outdated PRC-6/6. Its strange looking headset makes it an almost hands free radio ( only the PTT must be pushed. ) Besides, all the surrounding noise can be heard. Though the headset was developed for the army, the soldiers never grew accustomed to it. Thus SEM52-A was replaced after a rather short period by SEM-52S.
(SEM-53 with digital display was developed but not accepted).
It can co-operate with: RT-68, RT-70, RT-110, PRC-6/6, PRC-10, FSE-38-58, SEM-25, SEM-35, SEM-52S, SEM 70, SEM 80, SEM 90.
