Amateur radio can be enjoyed in many different ways. It is also an international 'language' allowing contacts all over the world. RTTY and HF Digital Modes Using an old teleprinter and now their modern PCs, radio amateurs can communicate with each other by typing away at their keyboards. This is the only mode so far that enables amateur computers to form a Local Area Network and allows many to share a radio channel at the same time. Satellite Communications International contacts are possible by using satellites orbiting the earth as repeaters of the radio amateur signals.
Radio amateurs take an active part in designing and building satellites for their own use.
An amateur radio trip. This can be anywhere - from the North Pole to remote unheard of islands, to your foreign holiday, or to remote uncharted jungles.
