The article discusses how to transform an old Android smartphone into a ham radio, specifically the kv4p HT project, which offers VHF voice and text communication capabilities. While the process requires some technical knowledge and tools like a printed circuit board and soldering skills, it can be completed for around $35. Users must also obtain a Technician class license to operate it legally in the U.S. Comprehensive building instructions are available online, along with a supportive community channel to assist in the process.
Smartphones have essentially all but replaced other methods of communication, but there are times when having access to a ham radio could be a lifesaver -- especially during disasters.
The project, called kv4p HT, is a homebrew VHF radio that is capable of both voice and text communication.
