There are some relevant sources: a forum post (EEVblog), a product page (Universal-Radio), a how-to guide (Summet.com), and manual pages (Manualslib). I'll open these to gather details. pages I've opened provide some information. For instance, the EEVblog post clarifies that the UI-7 adds FM transmit/receive and AM transmit, with the stock radio only receiving AM. The Universal-Radio page indicates it's for the IC-728. The Summet.com page details the UI-7 as an optional AM/FM unit for the IC-725, noting that the buttons might be present even if the unit isn't installed. The RigPix page lists compatible radios. The manual pages show installation instructions. However, I still need more details: features, installation, operation, compatible radios, user reviews, and current prices/availability. I'll conduct targeted searches to address these gaps. search results provide some additional leads. The results for "UI-7 Icom review" include a link to a forum post about the ICOM-728 and a classified ad for a UI-7 unit. The "IC-728 UI-7" search yields results about the IC-728 transceiver and its options. The "IC-721 UI-7" search results include a discussion about the IC-721 and UI-7. The "UI-7 AM FM unit for sale" results show a classified ad for a sold UI-7 unit. The "Icom UI-7 manual" results point to manual pages.
