Keyer-Power Supply

A Keyer-Power Supply is a device that combines the functions of a keyer and a power supply.

A keyer is a device used in amateur radio and telegraphy to generate Morse code signals. It allows the operator to send Morse code by pressing a key or paddle, which then generates the corresponding audio or radio signals.

A power supply, on the other hand, is a device that provides electrical power to other devices or equipment. It converts the available power source, such as AC (alternating current) from a wall outlet or DC (direct current) from a battery, into the appropriate voltage and current required by the connected devices.

A Keyer-Power Supply combines these two functions into a single device. It typically includes a keyer circuitry for generating Morse code signals and a power supply circuitry for providing the necessary electrical power to operate the keyer and other connected devices. This can be particularly useful for amateur radio operators who need both a keyer and a power supply in their setup.

Keyer-Power Supplies are available in various configurations and power ratings to suit different requirements. They may include additional features such as adjustable keying speed, tone generation, and voltage/current regulation for the power supply.
