4O3A Amplifiers
4O3A Power Genius XL HF/6M SO2R Amplifiers
4O3A Power Genius XL HF/6M SO2R Amplifiers are solid-state amplifiers capable of delivering 1500W+ output across the 160-6M amateur bands, engineered for high-performance amateur radio use. The PGXL uses dual NXP MRF1K50H LDMOS transistors, each rated for 1.5 kW, providing high headroom, low IMD, and clean signal output. It is the only amplifier with true SO2R capability, offering 70 dB isolation between two inputs. The integrated MEffA™ algorithm dynamically adjusts DC voltage for optimal efficiency. Additional features include fast SWR protection, advanced thermal management, and seamless integration with FlexRadio systems via SmartSDR. They also support third-party radios through Ethernet, RS232, CI-V, and BCD interfaces.

4O3A Power Genius XL 3X1 HF/6M Amplifiers
4O3A Power Genius XL 3X1 HF/6M Amplifiers are solid-state amplifiers capable of delivering 1500W+ output across the 160-6M amateur bands, engineered for high-performance amateur radio use. The PGXL 3X1 uses dual NXP MRF1K50H LDMOS transistors, each rated for 1.5 kW, providing high headroom, low IMD, and clean signal output. The Power Genius XL 3x1 features a 3-to-1 antenna switching module, allowing you to connect three antennas to a single radio. As a result, the software interface differs slightly to accommodate this functionality. The integrated MEffA™ algorithm dynamically adjusts DC voltage for optimal efficiency. Additional features include fast SWR protection, advanced thermal management, and seamless integration with FlexRadio systems via SmartSDR. They also support third-party radios through Ethernet, RS232, CI-V, and BCD interfaces.

4O3A 1A2R Radio Switches
The 4O3A 1A2R Radio Switch is engineered to allow a single amplifier to be safely shared between two radios, making it an ideal solution for SO2R (Single Operator Two Radios) contesting or multi-radio station setups. It uses a "first PTT wins" logic, ensuring that only one radio can access the amplifier at a time, preventing signal conflicts and potential equipment damage. Each radio's PTT control can be independently disabled via a dedicated switch, offering added flexibility during operation. Once installed, the switch eliminates the need for manual rewiring—your amplifier remains permanently connected and ready. In the event of a failure during SO2R operation, the amplifier can be quickly reassigned from Radio B to Radio A, providing a reliable backup path.

4O3A Switchable 3:1 Coaxial Power Splitter/Combiners
4O3A Switchable 3:1 Coaxial Power Splitter/Combiners can be used to split power between one, two, or three antennas/directions, or to combine two or three antennas. They are broadband, and capable of operating from 1.8–30MHz, with excellent matching and a well-designed PCB and circuitry. The PS-3000RX can be controlled using Station Genius or any manual switch controller that provides +12VDC for antenna selection. The SPLIT relay inserts a 50-to-22-Ohm transformer for matching when using two or three antennas.
