IC-7200 User Evaluation Test Report By Adam Farson VA7OJ/AB4OJ Iss. 4, 13 January 2013.Supersedes Iss. 3, December 3, 2008. Introduction: This report describes the evaluation of IC-7200 S/N 0201013 from a user perspective, as well as the results of several RF lab tests performed on the radio. I was able to spend a number of days with the IC-7200 in my ham-shack, and thus had the opportunity to exercise the radio’s principal features and evaluate its on-air behavior. Appendix 1 is the detailed test report. 1. Physical “feel” of the IC-7200: The IC-7200 conveys the solidity typical of a military tactical mobile radio set. I found the overall feel of the main tuning knob and other controls very smooth and pleasant. The rugged construction of the case and front panel, with the positive tactile feel of the Neoprene push keys, adds to this impression of solidity. The main tuning knob, with its chunky Neoprene grip, feels very smooth and has less than 0.5 mm side-play. The other rotary controls, some of which are detented, also have a positive feel. The large, concentric Twin PBT knobs are very comfortable to use; although the IC-7200 lacks the PBT CLR key found on other Icom DSP radios, the center detent facilitates setting Twin PBT to the neutral position. The radio is solidly constructed and superbly finished. It conveys a smooth, precise overall feel. The rear bumper protects the rear-panel connectors and heat-dissipator fins, and the optional front handles (if fitted) will protect the front panel and its controls from accidental damage. Installation of these handles is strongly recommended. 2. Multiple key functions and menus: Most of the front-panel keys have secondary functions which are accessed by pressing and holding the key for 1 sec. The digit-entry function of the numerical keys is actually secondary, and is entered by pressing the F-INP key. The yellow numerical digits are a clue to this, as the F-INP marking is yellow. The
