Ermis (AlberBlanc/FalconIon)

Company connections · Japanese HF callsign withheld · U.S.: FalconION / WM2XHW

Shimoizumi transmits; Maeda receives. Ermis’s declared Illinois receiver matches FalconION’s Manhattan site. A separate Nuvio Tech application proposes using Maeda for a California–Japan link.

Shimoizumi, Sodegaura

Two guyed towers, each with a twelve-element log-periodic. The western tower also carries the space-diversity microwave pair.

Site grading was complete in February 2025 imagery. Ryota saw no towers during his 2 March pass; by 5 July 2025, both arrays and the microwave dishes were installed, with the site still under construction.

The Japanese HF licence followed on 1 December 2025, naming Johor Bahru and Manhattan. The public record withholds the callsign.

Shimoizumi ↔ Shin-Toyosu Cube · 33.3 km

Ryota ties these dishes to the new space-diversity pair added at the Cube between 12 July and 9 August 2025. The bearing and clear sightline give Ermis a direct Tokyo connection, without one of the Ariake rooftop hops used by several operators.

Our MIC analysis also finds the corresponding Sodegaura–Kōtō channel pair.

Sixteen TCI loops in two rows of eight, around 4 m high and 4 m apart. Ryota photographed the installation on 1 June 2025 and found fibre service to the site.

The loops form a steerable receive array. Its physical southwest alignment alone does not identify the received path; the onward fibre destination is also unknown.

Nuvio’s proposed California → Maeda path

Nuvio Tech’s 0760-EX-CN-2026 FCC application places its Japanese receiver at this installation. Its path diagram shows California to Japan.

The coordinates identify Maeda; the business arrangement between Nuvio and Ermis/FalconION remains unknown.
