The RM Italy KL-503 HD is a 300W linear amplifier for the 25–30 MHz band — covering the full CB band (27 MHz) and the 10m amateur band (28–30 MHz). Designed for mobile or base station use from a 12V supply, it accepts 1–35W of drive power across all modes (AM, FM, SSB, CW), making it compatible with a wide range of CB and 10m transceivers.

A six-position power selector on the front panel allows output power to be adjusted to suit operating conditions or licence requirements. An RX preamplifier with electronic switching — activated via a front panel switch — boosts received signal sensitivity when needed. Made in Italy.
