Complete IC-7851 test report now on-line by Adam, VA7OJ/AB4OJ

IC-7851 HF/50MHz transceiver with new features such as a 1.2kHz optimized roofing filter, (IC-7850 is a special 50th years Icom anniversary model of 150 units only on the world) Complete Test Report by Adam, VA7OJ/AB4OJ is now on-line on his web-site (un’altro eccellente lavoro di Adam, VA7OJ …  tnx! grazie)

VA7OJ-photoThe Test Report (download the large pdf, link below) are the results obtained from lab tests which the author conducted on Icom IC-7851 S/N 02001019, kindly loaned by Allan, VE7SZ. The installed firmware version were V1.01 for the receiver test and V1.11 for the trasmitter tests. The baseline configuration for all receiver test was MAIN Receiver, NR/NB/ATT/Notch off, AGC Slow.

Ic-7851 (or IC-7850) in HF/50MHz operation with new features such as a 1.2kHz optimized roofing filter to improve in-band  adjacent signal performance.

IC-7851_BPF-Roofing-Mixers

The IC-7851 employs a Direct Digital Oscillator (DDS) with a voltage controlled “SAW” Oscillator (VCSO). This new 1st LO Icom design sets a new benchmark for phase noise with -150dBc/Hz at 10kHz offset (-140dBc/Hz at 1kHz offset) and two receivers (Main/Sub) in up-conversion design.

RS-BA1 Ver.1.80 Enanced Functions and Features Icom Update 2015/07/17

RS-BA1 IP Remote Control Software Icom Update Ver. 1.80, Enhanced Functions and Features – Now the high- resolution spectrum scope with waterfall function can be observed on the RS-BA1 (1.80) for a single band on only the IC-7850 and IC-7851 – You must have a previous version of the RS-BA1 software installed BEFORE you can update to version 1.80.
RS-BA!_180-slider

In addition to the conventional tuning knob controls, some items can be adjusted with slider controls (see pictur above) The slider controls provide visual and fine adjustment within the the function’s range.

Thanks to the Internet, hams !!! now have the ability to remotely operate any station at any distance – all without the complication and limitation of RF linking or a big anetnna farms, hi! – Maybe you have a well-equipped home station and you’d like to share your good fortune with some of your friends via overIP ADSL Internet. Or, perhaps you are a ham living under onerous restrictions and you’d like to establish a remote station so that you can finally get on the air!

IC-7200-manpack

This has created a boon in remote station control, making it possible for hams to continue enjoying their hobby regardless of where they live.  Among professionals this is known as Radio over IP or RoIP. — (IC-7200 only for vision!)

IC-7850 Special Edition & IC-7851 flagship machines impressive 110dB RMDR

IC-7851 HF 50MHz Transceiver, the series-production version of the IC-7850 Special Edition which offers a number of improvements over the IC-7800. – The two transceivers utilizes a newly developed 1.2kHz “Optimum” Roofing Filter operating at 64MHz (1st IF). Automatic or manual adjustment is possible of this Roofing Filter! – See the IC-7850 Video by IV3YER, Luigi, and download the new User Manual “ENG” Version, by link below.

Improvements in RMDR (Reciprocal Mixing Dynamic Range) (data from Icom broshure)

RMDR a spaziatura di 1kHz su frequenza di ricezione: 14.2 MHz, MODE: CW, IF BW: 500Hz – (Per IC-7800: roofing di 3 kHz, per IC-7851: “Optimum” roofing di 1,2 kHz)
Icom back now to use a Direct Digital Synthesizer (DDS) along with a Phase Locked Oscillator for the IC-7851’s Local Oscillator (LO) as did in IC-7850’s, will become the new benchmark for Phase Noise with –150dBc/Hz at 10kHz offset and –140dBc/Hz even at 1kHz offset. (… see broshure)

Icom torna ora ad utilizzare un Direct Digital Synthesizer (DDS), insieme ad un Oscillatore ad aggancio di fase per il nuovo Local Oscillator (LO) dell’IC-7851. (vedere dati Icom)
