What follows are my personal impressions regarding the features and usability of this radio. This, in no way, should be viewed as an endorsement to purchase this radio nor is it intended to discourage anyone from buying it. I have no personal nor business relations with Icom (US, UK or Japan). These are simply thoughts offered to my fellow hobbyists who may be interested in purchasing this particular software or simply knowing more about it.

A lot of hard work and effort has gone into the testing and writing of this review. I would appreciate it if every effort is made to keep this document whole with me as the original author.
