Icom launch IC-7851 Flagship HF/50MHz Amateur Radio Transceiver

Radio manufacturer, Icom have a strong heritage of building the most
sophisticated Amateur radio transceivers. Decades of technical expertise
and engineering experience have brought top of the range models from the
IC-781 to the IC-7800. Icom now are pleased to launch the latest generation
of high end HF transceiver called the *IC-7851*!

The *IC-7851* <http://www.icomuk.co.uk/IC-7851> is the company's new
flagship amateur radio and incorporates a new local oscillator (LO) design,
an optimized roofing filter, enhanced spectrum scope to name but a few of
its many functions. 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 1.2
kHz 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* <http://www.icomuk.co.uk/IC-7851> also features enhanced
spectrum scope functionality.
A dedicated Digital Signal Processing (DSP) unit is used for the Fast
Fourier Transform (FFT) spectrum to provide faster sweep 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 a 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.

The radio is available to order from all authorised IC-7851 Amateur radio
dealers with a suggested retail price of £9000.00 inc. VAT.
