So ive found this military radio from a surplus store that i got a tanker helmet from , and told myself why not buy this radio (it's a VHF RV-2/400) so maybe i can aslo make the helmet work on the radio but if not it could still be great to own it since being quite cheap , the only issue is i mostly cant find any information about it anywhere , so i dont know if it could still work today , how to make it work and how to use it
