Icom IC-7851 200W HF/50MHz Competition Transceiver

Icom IC-7851 HF/50MHz Transceiver: The Ultimate HF/50MHz Contest and DX Platform

Introducing the Icom IC-7851, the flagship HF/50MHz transceiver that sets the absolute standard for spectral purity and dual-receiver performance. Engineered for elite contesters and demanding DX operators, the IC-7851 utilizes solid design basics and cutting-edge technology to give you a competitive advantage on the air.

Experience crystal-clear reception and effortless signal extraction, even in the most crowded band conditions, thanks to Icom’s focused engineering on phase noise reduction and next-generation DSP power.

Breakthrough Receiver Purity and Dual-Band Capability
The IC-7851 is built to hear what other radios can't. Its innovative Local Oscillator (LO) and solid-state design deliver unparalleled performance:

• Exceptional RMDR: Achieve a Reciprocal Mixing Dynamic Range (RMDR) of 110dB—a direct result of a new, ultra-low phase noise LO system that dramatically improves your ability to copy weak signals next to strong local interference.
• True Dual Receivers: The radio features two completely independent receivers, each with dedicated high-performance DSP processing, giving you a dual scope portal into the RF world.
• Dual AGC Loops and Image Rejection Mixing: Advanced AGC architecture prevents saturation, while the image rejection mixer ensures a simple, distortion-free receiver system, minimizing spurious signals and maximizing dynamic range.
• High Stability OCXO: The Oven Controlled Crystal Oscillator (OCXO) delivers frequency stability of ±0.05ppm, ensuring highly accurate and drift-free operation across all bands, including 50MHz.

Powerful Output and Connectivity
Designed for the most advanced operators, the IC-7851 offers robust power and supreme operational flexibility:

• Reliable 200W Output: The push-pull power amplifiers utilize power MOS-FETs operating at 48V DC, providing a powerful, full-duty cycle 200-watt output across HF and 50MHz with low transmit intermodulation.
• Advanced Antenna Management: With six antenna ports (four Rx/Tx and two Rx-only), plus an improved automatic antenna tuner, you have fingertip control over complex antenna configurations, with automatic switching based on the selected band.
• PC-Free Digital Modes: The internal memory keyer supports both CW and digital modes (RTTY, PSK31/63), allowing you to log and transmit stored messages without connecting an external PC.
• Ultimate Remote Control: Features an internal remote base server and an Ethernet jack, allowing you to connect directly to your router for seamless, responsive remote control via the optional RS-BA1 software without needing a separate shack computer.

The Icom IC-7851 is more than a radio; it's a competitive advantage built into a solid, beautifully crafted aluminum chassis. Bring home the pinnacle of HF communications performance.
