The RM KL-703 is the highest-power amplifier in the RM KL range, delivering up to 500W output across AM, FM, SSB, and CW modes from the 25–30MHz band (CB and 10m). It accepts a wid e drive range of 1–35W, making it compatible with both low-power and higher-power transceivers. Two heatsink-mounted cooling fans ensure sustained high-power operation, and a three-position output power selector on the front panel allows precise power control. A built-in RX preamplifier with electronic switching is 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 amateur and CB frequencies.
