I have drafted a couple of sheets for people using the radios who haven't been on the course. They give an idea of how to make routine calls to London VTS and how to make a Mayday distress call. If people think these are worth having around maybe we could laminate a few copies. Feel free to disagree with the idea or edit the content.
