Icom Announces New IC-7851 HF/50MHz Amateur Radio

            

Icom America introduces the new IC-7851, the company's new flagship amateur radio. This high frequency transceiver employs a new local oscillator (LO) design, an optimized roofing filter, enhanced spectrum scope and other standout features. Raising the bar for HF operation, the IC-7851 is ideal for contesters, DXers and the serious amateur radio operator.

Icom's new radio features a new LO design which utilizes a Direct Digital Synthesizer (DDS) along with a Phase Locked Oscillator. This configuration reduces phase noise and achieves a reciprocal mixing dynamic range of 110dB. A 1.2kHz optimized roofing filter overcomes the gap of a narrower roofing filter in an up-conversion receiver. and greatly improves in-band adjacent signal performance.

The IC-7851 also features improved phase noise characteristics as well as enhanced spectrum scope functionality. A dedicated Digital Signal Processing (DSP) unit is used for the Fast Fourier Transform (FFT) spectrum to provide faster sweeps speeds and finer accuracy. Audio scope and dual scope functions, combined with a high-resolution spectrum waterfall display, provide twice the speed, sensitivity and control to give operators an performance edge.

Other radio highlights include USB-enabled click and enhanced PC control. When combined with the optional Icom RS-BA1 software, the IC-7851's internal server promotes remote base station operation. The radio can connect directly to a router and does not require a second computer for audio or rig control. The IC-7851 also continues various benchmarks established by Icom's celebrated IC-7800 such as +40dBm iP3 (3rd order intercept point), 200W output power at full duty cycle and more.
