Amateur Radio Station
The hobby of amateur radio is interesting after more than 40 years and has undergone many technology changes over those years. Building and operating an ARS brings together many disciplines that enable communications around the world. Now with computer technology and the Internet, amateur radio has been extended into the digital world.
Many amateurs still operate "valve" construction radios so that tube technology, available at the beginning of radio, lives on; some examples show to the right.

Today, radios have become very small, utilize processors to run computer programs, and have the ability of change features through software updates - Software Defined Radio (SDR) - "Flex radios".
