Homebrew is an amateur radio slang term for home-built, noncommercial radio equipment. [1] Design and construction of equipment from first principles is valued by amateur radio hobbyists, known as "hams", for educational value, and to allow experimentation and development of techniques or levels of performance not readily available as commercial products.
The program is designed for sending and receiving low-power transmissions to test propagation paths on the MF and HF bands. WSPR implements a protocol designed for probing potential propagation paths with low-power transmissions. Transmissions carry a station's callsign, Maidenhead grid locator, and transmitter power in dBm.
As an "all-band" transceiver, the TS-2000 offers a maximum power output of 100 watts on the HF, 6 meters, and 2 meters bands, 50 watts on 70 centimeters, and, with the TS-2000X or the optional UT-20, 10 watts on the 1.2 GHz or 23 centimeters band. The (American version) radio's main receiver covers 30 kHz through 60 MHz, 142 MHz through 152 MHz ...
The AN/PRC-160 Wideband HF/VHF Manpack Radio is a tactical HF/VHF manpack radio manufactured by L3Harris. The PRC-160 is the manpack HF radio for the Harris Falcon III family of radios. The PRC-160 is the manpack HF radio for the Harris Falcon III family of radios.
RF power amplifiers using LDMOS (laterally diffused MOSFET) are the most widely used power semiconductor devices in wireless telecommunication networks, particularly mobile networks. [ 4 ] [ 10 ] [ 6 ] LDMOS-based RF power amplifiers are widely used in digital mobile networks such as 2G , 3G , [ 4 ] [ 6 ] and 4G [ 10 ] and the good cost ...
Also, it was popular in Soviet-era DIY audio amplifiers for hi-fi and musical instruments. GU-50 tubes were used also in early TV sets as a horizontal sweep output stage, and in medical devices as RF generators. The tube was never used in mass production amplifiers for civil usage because of relatively expensive technology and materials used.
High-frequency direction finding, usually known by its abbreviation HF/DF or nickname huff-duff, is a type of radio direction finder (RDF) introduced in World War II. High frequency (HF) refers to a radio band that can effectively communicate over long distances; for example, between U-boats and their land-based headquarters.
6N3C power tube. A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers in the 1960s and 1970s.
