RM HLA300V 4

RM HLA300V HF amplifier is designed to operate within the frequency range of 1.8 to 30MHz, providing a maximum power output of 300W.


The RM Model HLA 300V Black is a versatile amplifier covering a wide frequency range from 1.8 to 30 MHz, making it suitable for all-band operation in all modes. With up to 300 watts (550PEP) of power available, this amplifier provides the necessary boost to effectively work weaker DX stations. It boasts essential features such as electronic switching, PTT input, a wattmeter, forced multispeed ventilation, and six low-pass filters that can be manually or automatically selected.

Operating on a 12-14v power supply, the RM Model HLA 300V Black requires 40A of input energy/power. Its input power ranges from 2 to 15 watts and 2 to 20 watts for SSB operation. The output power reaches a maximum of 200 watts and 400 watts for SSB. This amplifier, equipped with a microprocessor and electronic switch, also includes SWR and thermal protection, a watt meter, band selector, PTT switch, and 6 low-pass filters for enhanced performance.

Weighing only 3.3 kg and compactly sized at 450x190x70 mm, the RM Model HLA 300V Black is designed with user convenience in mind. It features 3 fans for efficient cooling, ensuring optimal performance during operation. The built-in protection circuitry also safeguards the amplifier from potential damage in case of high spurious emissions or incorrect band selection. Remember not to exceed the input power limits to avoid costly repairs, as overdriving the amplifier may void the warranty. For further information or assistance, do not hesitate to contact the manufacturer, RM Italy.
