President RICHARD II 10m/12m AM/FM Amateur Radio Transceiver with NRC Filter and USB-C

Summary

The President RICHARD II amateur radio transceiver is a powerful and versatile mobile model designed for radio enthusiasts operating on the 10m and 12m decametre bands. Developed by President Electronics, it combines robustness, modern ergonomics and adjustable power output for mobile or fixed-base operation. Its cutting-edge features, such as NRC digital audio processing and USB-C fast charging, make it an essential piece of kit for both DX and local operations.

Key features

• Independent NRC noise processing: Active digital noise reduction, configurable separately for transmission and reception, ensuring perfectly clear sound.
• High DX power: Delivers up to 40 W in FM and 50 W PEP in AM, with the option of software-based power limiting (4 W / 10 W) depending on operational requirements.
• Front-panel USB-C fast charging port: USB Type-C port delivering up to 20W (5V/3A, 9V/2.22A, 12V/1.67A) to power smartphones and accessories directly from the radio.
• Dual standby and comprehensive audio filters: Features ASC, Noise Blanker (NB), Automatic Noise Limiter (ANL) and a Hi-Cut filter to eliminate ignition interference and background noise when operating on the move.
• Digital SWR meter and safety alerts: Direct SWR measurement with audible signal and built-in protection against overvoltage and excessive SWR to safeguard the output stage.
• Advanced customisation: Backlit LCD display with 7 interchangeable colours, 6-tone Roger Beep function, adjustable talkback and built-in echo.
