Amateur radio, also known as ham radio, describes the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication.
The ampere (symbol: A), often shortened to "amp",SI supports only the use of symbols and deprecates the use of abbreviations for units.
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current).
The BC107, BC108 and BC109 are general purpose low power Silicon NPN bipolar junction transistors found very often in equipment and electronics books/articles from Europe, Australia and many other countries.
The BC548 is a general-purpose NPN bipolar junction transistor commonly used in European and American electronic equipment.
An electric current is a flow of electric charge.
Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit.
The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI) and is defined as one cycle per second.
The KT315 is a Soviet NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications, enclosed in the plastic KT-13 package.
A microcontroller (MCU for microcontroller unit, or UC for μ-controller) is a small computer on a single integrated circuit.
Motorola, Inc. was an American multinational telecommunications company founded on September 25, 1928, based in Schaumburg, Illinois.
A small outline transistor (SOT) is a small footprint, discrete surface mount transistor commonly used in consumer electronics.
Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs).
The TO-92 is a widely used style of semiconductor package mainly used for transistors.
The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.
Voltage, electric potential difference, electric pressure or electric tension (formally denoted or, but more often simply as V or U, for instance in the context of Ohm's or Kirchhoff's circuit laws) is the difference in electric potential between two points.
The watt (symbol: W) is a unit of power.
The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications.
The 2N2907 is a commonly available PNP bipolar junction transistor used for general purpose low-power amplifying or switching applications.
