I have made up the punch bowl and everything else for the radio, have done the thing with the butter knife, and have the radio turned on. I can't find how to call anyone by using the radio. It says that I can't just call anyone, it has to be someone in particular. I have studied all my documents and tried to join things up with the morse code book, but nothing works. I cannot talk to anyone else or doanything else at the moment until this task is complete. Can anyone help?
