DATACOM (IMC) — source notes

The IMC dossier presents the site photographs and route summary. Company connections.

• Photograph dates: 20230719sodegaura.jpg in Mother Farm (English) was taken on 8 July 2023; the filename uses the publication date. The 24 November 2024 revisit (English) supplies the other end of the dossier's installation interval. The Yagi and microwave additions both fall within that interval, without a shared installation date established.
• Yagi callsign: the February 2026 comparison (English) explicitly labels the added Yagi JS2RB, although it sits on the east tower with JS2RA's log-periodics.
• Unnamed southeast link: the dish is visible in the November 2024 photographs (English); the E-band designation comes from the later schematics, including the August 2026 diagram (English), which leaves its endpoint unnamed.
• Earlier licence inventory: Ryota's experimental-callsign search (English) includes JS2RA in January 2023 and adds JS2RB on March 26. It also preserves his registry-search method and Perl code.
