The Icom IC-7850 is a very special limited edition enhanced version of the iconic IC-7800. Only about 150 IC-7850 units (worldwide) will be released as a limited edition to commemorate Icomís 50th anniversary.
It perfects HF operation with new features such as a 1.2kHz optimized roofing filter to improve in-band adjacent signal performance. The new radio's up-conversion design supports a dynamic range that outperforms competitors' similar models in the 2 to 10 kHz separation tests. Unlike HF rigs that use a conventional voltage controlled oscillator for the 1st LO, the IC-7850 employs a direct digital oscillator (DDS) with a voltage controlled SAW oscillator (VCSO). This new 1st LO design sets a new benchmark for phase noise with -150dBc/Hz at 10kHz offset (and -140dBc/Hz at 1kHz offset). Icom's IC-7850 also features the spectrum waterfall function found in the manufacturer's IC-7700 and IC-7800 upgrade models. The high-resolution waterfall screen shows the changing amplitude of frequencies over time. An enhanced spectrum scope promotes fast and accurate scan and can be operated with PC mouse via USB port. A dual scope function shows simultaneous activity in both bands. This is useful for searching a sub-band while maintaining a run frequency on the main band.
We will add more technical information, pricing and availability as soon as it is announced.
