The RM KL-203 is a high-power 12V linear amplifier for the 25–30MHz band (CB and 10m), delivering 100W output in AM/FM mode and 200W in SSB mode. It accepts 1–5W drive in AM/FM and 2–10W in SSB, making it compatible with most CB and 10m transceivers. The KL-203 shares the same output power as the KL-200 but without the built-in preamplifier. For the version with a built-in 25dB RX preamplifier, see the RM KL-203P. 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.
