The RM KL-300 is a high-power 12V linear amplifier for the 25–30MHz band (CB and 10m), delivering 140W output in AM/FM mode and 250W in SSB mode. It accepts 1–10W drive in AM/FM and 2–20W in SSB. The KL-300 shares the same output power as the KL-300P but without the built-in preamplifier, making it the cleaner choice where RX preamp is not required. For the version with a built-in 25dB RX preamplifier, see the RM KL-300P 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.
