Even in the 21st century, modern communication technology is still affected by natural disasters and political turmoil which threaten people's lives and make the Internet or mobile phone networks unavailable for use. This work is based on constructive research which resulted in a proof of concept system that uses shortwave radio technology to provide a one-way communication system. A message that a user writes on their smartphone, which is connected to a small preset transmitter, is sent out to a receiver in another part of the world where the message can then be posted on the Internet. This system is a cheaper alternative to other shortwave radio transmitters, and has potential for improvement.
