Why Buy?

Linear Power Amplifiers boost your radios output power. Note the rated power is a theoretical maximum, and not a realistic average output. Due to the technologies of modulation expect about half the rated power as the average or nominal output. Amplifiers require extensive knowledge to install and operate for the safest results.

Push your QRP signal to the limit with the RM Italy KL300P. This is a high-performance 12V mobile amplifier designed for licensed Amateur Radio operators. It takes a low-power 10W radio and boosts its signal to 140W (AM/FM) or 250W (SSB), ensuring you can be heard.

More than just a transmitter, the KL300P is a complete station accessory. The "P" in its name stands for its built-in 25dB receive pre-amplifier, which can be switched on to "pull in" weak and distant stations. With automatic TX/RX switching (VOX), this compact Italian-made unit is the ultimate upgrade for any 10 or 12-Meter mobile or base station.

⚠️ CRITICAL: Maximum Input Power

This amplifier is designed for low-power QRP radios ONLY. The maximum recommended input power is:

10 Watts (AM/FM)
20 Watts (SSB)

Applying more power than this will destroy the final transistors and void the warranty. This amplifier is NOT compatible with 100-watt transceivers (like the Icom 7300 or Yaesu 891/991) or high-power 40W+ CB radios.

Warranty & Installation Notice

Please note, linear amplifiers require appropriate licensing to install and operate. These units are not designed for a 100% duty cycle. All units are fully tested and inspected before shipping; however, there are no returns and a limited (Manufacturer's) warranty applies.

RM Italy is located in Italy, and warranty claims must be processed with the manufacturer. Setup and testing should only be performed by qualified individuals.
