The RM KL-300P is the top-of-range 12V linear amplifier in the RM KL series, covering 25–30MHz (CB and 10m) and delivering 140W output in AM/FM mode and 250W in SSB mode — the highest output in the range. It accepts 1–10W drive in AM/FM and 2–20W in SSB, and includes a built-in 25dB RX preamplifier with electronic switching activated via a front panel switch. Note: Always ensure your antenna system is correctly matched (SWR within specification) before using a linear amplifier. Check local regulations regarding the use of linear amplifiers on CB frequencies.
