description Heathkit HP-23 Overview
The Heathkit HP-23 is an AC power-supply kit made for fixed amateur-radio stations and used with Heathkit transceivers such as the HW-101. It supplies the operating voltages required by compatible tube-based equipment through the HP-23 and related PS-23 series, making it a companion unit rather than a radio receiver or transmitter; servicing requires care because the circuit contains potentially lethal high voltages.
help Heathkit HP-23 FAQ
What does the Heathkit HP-23 power supply do?
The HP-23 is an AC power supply kit that provides the high voltage and other supply voltages needed by compatible amateur-radio transceivers. It is an external power unit, not a transmitter or receiver by itself.
Which Heathkit radios commonly used the HP-23?
The HP-23 was designed for tube transceivers such as the Heathkit HW-101. Compatibility depends on the exact HP-23 version and the radio's required voltages and connector wiring.
Is the HP-23 a mobile DC power supply?
No, the HP-23 is an AC-operated supply intended for a mains-powered station. A mobile installation would require a different type of power conversion equipment designed for a vehicle's DC system.
Why is restoring an HP-23 potentially dangerous?
The unit generates high voltage for tube radio equipment, and its capacitors can retain a charge after the power is removed. The power supply should be inspected and safely discharged before any repair or first-time startup.
