Dear Ham Friends, Rate My Radio was lucky enough to get a loan unit of the IC-R8600, and have compared it over 1 hour to the IC-7610! The antenna is the same, split with a commercial grade Mini-Circuits ZSC-2-2+ which performed amazingly; the phase difference was almost unnoticeable. Check the video out here, click the 'Youtube' logo bottom right for full details and raw audio files (you must click play first): The results are amazingly close... which do you prefer? 73, Jarrad VK3BL & the Rate My Radio Team
