The Amateur Radio (Ham Radio) Hobby
Getting an amateur radio
license became a lot easier beginning in 2007 because you no
longer have to know Morse code.

http://www.arrl.org/arrlvec/license-requirements.html Amateur Radio License Levels and
Requirements
With an amateur radio license you use it for friendly chat around the world. You can build your own radio equipment. You can use amateur radio satellites up in space. You can bounce radio signals off of the moon.
Many of the technology and inventions that have come around this century have come around from ham radio. The IP protocol that the Internet works on today, basically was pioneered by ham radio operators as an experimental protocol. Two-way text messaging was common for hams in the mid 1980s before consumers had it in the late 2000s.
The use of ham radios during times of disasters is priceless. When a hurricane, a major tornado, a major earthquake, a major flood, a major terrorist attack, or other disasters disrupts the communication infrastructure, ham radio operators go into action to set up a emergency communications.

The amateur radio service is a "Radiocommunications service for the purpose of self-training, intercommunication and technical investigations carried out by amateurs, that is, by duly authorized persons interested in radio technique solely with a personal aim and without pecuniary interest." Radio amateurs are trained and experienced in electronics, propagation theory, and communications techniques. Amateurs also respond swiftly and effectively to calls for communications assistance when normal channels are lost. The amateur service has significantly contributed to the development of radio technology. Amateur operators continue to fulfill certain public service radiocommunications requirements, and increase their skills relating to emergency communications. During natural disasters such as hurricanes, floods, and other events, amateur radio communications have been particularly effective, and in many cases have been the sole means of communicating from the scene of a disaster.
In addition to recreational use, amateurs use the amateur bands to provide public services in a variety of ways. The American Radio Relay League (ARRL) sponsored National Traffic System provides a nationwide network that carries thousands of messages monthly. This system is available in the event that regional or local disasters degrade the public communications systems. The Department of Defense (DOD) works closely with the amateur community in its Military Affiliate Radio System (MARS) network. Local amateur radio clubs provide communications support for community events, and are a source of trained radio operators to complement state and local communications personnel through the Amateur Radio Emergency Service (ARES) and Radio Amateur Civil Emergency Service (RACES) programs.
Amateurs, or "ham" radio operators, provide a unique service to the public while enjoying a popular, technical hobby. Many innovative uses of radio systems have been developed by amateurs for use in the amateur bands, such as packet-switched systems, amateur television, and the amateur-satellite service. Amateurs are always experimenting with point-to-point systems to push the state-of-the-art in antenna design and solid-state equipment, and to investigate the properties of signal propagation. Amateurs use Morse code, voice, packet-switched data, television, and satellite communications in the various frequency bands. It is estimated that there are more than 632,000 amateur radio operators in the United States, and over 2.4 million worldwide.
