The R30 and R8600 were announced together by Icom at a trade show in Japan. I remember translating the trade shows brochure someone had posted here before they had FCC approval. They eventually did publish an announcement and brochure in English for the two receivers for the US market but dealers could not offer them for sale or even mention a price until they received FCC certification.If we could get allot of folks to send Icom a message to build a desktop version of the R30, maybe they will build it. But with chips for radios super low, could be awhile if they did.
I always took that to mean the 8600 was intended to be the desktop version of the R30. The two do share 'some' of the same features such as the modes they are capable of receiving but many other features are not shared between the two.
Then the 8600 does not have dual VFO's either.
