I hope you enjoy the blog! Amateur radio is a fun way to mess around with technology, meet new people, and communicate off the grid. Talking directly to another radio on a single frequency also called simplex is the easiest way to get started. However, it can be difficult to communicate over longer distances without amplifiers, proper wiring, and antennas. This is where a radio repeater can help. The most common frequencies for local communication in these bands are:. Some of those bands require advanced FCC licensing that takes additional studying and practice.

Amateur radio repeater
An amateur radio repeater is an electronic device that receives a weak or low-level amateur radio signal and retransmits it at a higher level or higher power, so that the signal can cover longer distances without degradation. Many repeaters are located on hilltops or on tall buildings as the higher location increases their coverage area, sometimes referred to as the radio horizon , or "footprint". Amateur radio repeaters are similar in concept to those used by public safety entities police, fire department, etc. Amateur radio repeaters may even use commercially packaged repeater systems that have been adjusted to operate within amateur radio frequency bands, but more often amateur repeaters are assembled from receivers, transmitters, controllers, power supplies, antennas, and other components, from various sources.
Amateur radio frequency allocation is done by national telecommunication authorities. Globally, the International Telecommunication Union ITU oversees how much radio spectrum is set aside for amateur radio transmissions. Individual amateur stations are free to use any frequency within authorized frequency ranges; authorized bands may vary by the class of the station license. Radio amateurs use a variety of transmission modes, including Morse code , radioteletype , data, and voice. Specific frequency allocations vary from country to country and between ITU regions as specified in the current ITU HF frequency allocations for amateur radio.
