Icom Inc. introduces the new IC-7850, a transceiver HF/50 MHz. Pre-release information to the new Icom amateur radio facility was recently shared at JARL Ham Fair 2014 (Tokyo Ham Fair 2014), which took place on 23-24 AUGUST in Japan. New features IC-7850 include but are not limited to: enhanced coverage, new filter first local oscillator (LO) the design and improved spectrum scope. Drive approximately 150 IC-7850 (worldwide) will be released in a limited edition to commemorate the 50th anniversary of the company.
The IC-7850 perfect functioning HF with new features like a 1.2 kHz roofing filter optimized for better performance in-band adjacent signal. Up-conversion design of the new radio supports a dynamic range exceeding similar models competitors in 2 to 10 kHz separation test. Unlike HF systems 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 (VCSOS). This new Prime design sets a new benchmark for phase noise with-150dBc/Hz at 10 kHz offset (e-140dBc/Hz at 1 kHz offset).
Icom IC-7850 also offers the function spectrum waterfall found in IC-7700 manufacturer and models from update IC-7800. The high resolution screen waterfall view the amplitude frequency changeable over time. An improved spectrum scope promotes rapid and accurate scanning and can be operated with the mouse to the PC via USB port. A dual purpose function shows the activity simultaneously in both bands. This is useful for finding a sub-band while maintaining a working frequency on the main band.
