RM KL-203P MOSFET Linear Amplifier. 0.5W – 10W AM/FM, 1 – 20W SSB input; Up to 100W AM/FM 200W SSB output; 13.8V DC; Switchable SSB Delay Relay; 26 db gain Pre Amplifier

The RM KL203 Linear Amplifier is a robust amplifier designed to provide a substantial power boost across the 28-30 MHz frequency range. Delivering a solid 100-watt output enhances signal strength for various modes of operation.

The KL-203P is a very compact amplifier and a solid performer. I must reiterate the point that these are low drive amps. I achieve the best performance for my needs at or below 2W drive and typically operate these at ~1.5W input. At 1.5W drive it generates ~40W AM deadkey and @3.0W average power in it yields ~55W average (not PEP) on SSB.

The KL 203 is an impressive 12V linear amplifier explicitly designed for the 28 – 29.7 MHz frequency range, making it an excellent choice for amateur radio enthusiasts. With a drive power requirement ranging from 1 to 10 watts, this amplifier supports various modes, including AM, FM, and SSB, ensuring versatility in communication.
