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.
In electronics, motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones.

The AN/PRC-150(C) Falcon II Manpack Radio, is a tactical HF-SSB/ VHF-FM manpack radio manufactured by Harris Corporation. [1] It holds an NSA certification for Type 1 encryption . [ 2 ] The PRC-150 is the manpack HF radio for the Harris Falcon II family of radios, introduced in the early 2000s.
EICO is also known for "monoblock" amplifiers such as the HF-50 and HF-35, stereo integrated amplifiers such as the ST-40 and ST-70, as well as many other amplifiers and preamplifiers. In the late 1960s, EICO introduced a line of solid state electronics audio equipment referred to as Cortina , but by the mid-1970s the only audio products they ...
A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal. [1] Typically, RF power amplifiers are used in the final stage of a radio transmitter , their output driving the antenna .
The PRC-160 is the manpack HF radio for the Harris Falcon III family of radios. It replaces the earlier AN/PRC-150 , with a smaller form factor and lighter weight than its predecessor, and being capable of 4th Generation Automatic Link Establishment (4G ALE), achieving data transmission speeds up to 10 times faster.
The GU-50 (Russian: ГУ-50) is a power pentode vacuum tube intended for 50 watt operation as a linear RF amplifier on frequencies up to 120 MHz. It is, in fact, a Soviet-produced copy of the Telefunken LS-50 power pentode, [ 1 ] possibly reverse-engineered from German ( Wehrmacht ) military radios captured during World War II , or based on ...
