TL;DR — 세 문장

  • HERMES is an open-source digital shortwave radio from Rhizomatica founder Peter Bloom, operating in the 3 to 30 MHz HF band alongside its Mercury digital modem. [S1]
  • The system runs about 20 watts of transmit power and targets 400 to 600 km ionospheric point-to-point links, compared with conventional HF digital rates that IEEE Spectrum pegs in hundreds of bits per second. [S1]
  • A Bangladesh pilot equipped 10 or 11 artisanal fishing boats, and one 100 to 200 km offshore sent GPS coordinates and an SOS that helped coordinate a rescue. [S1]

Reported by IEEE Spectrum on 2026-09-21. Summarized and analyzed by XAIPART Editorial.

What happened

Peter Bloom, founder of Philadelphia-based nonprofit Rhizomatica, has open-sourced a digital shortwave radio set called the High-frequency Emergency and Rural Multimedia Exchange System (HERMES), designed to bring file-level data connectivity to remote, indigenous, and off-grid communities.S1

The radio operates in the high-frequency (HF) band from 3 to 30 megahertz, the same band used by Mercury, its companion digital modem.S1 Compared with conventional shortwave digital transmissions that the source pegs in hundreds of bits per second, Bloom told IEEE Spectrum that HERMES uses small radios outputting about 20 watts and can "pretty reliably" establish 400- to 600-kilometer point-to-point links by reflecting signals off the ionosphere.S1

Bloom described HERMES as a software stack that transports arbitrary files - emails, photos, voice memos, GPS coordinates - over HF rather than carrying only voice traffic.S1 He cited a Bangladesh pilot with 10 or 11 artisanal fishing boats in the Bay of Bengal: after the system was installed, one boat 100 to 200 kilometers offshore sent its GPS position and an SOS during a mechanical failure, helping coordinate a rescue.S1

Encryption is built in but optional, because amateur-radio rules vary by country and Bloom said some partners operate in sensitive areas where plain transmissions would put users at risk.S1 Rhizomatica staff deploy HERMES in countries including Bangladesh, Brazil, and Ecuador.S1

XAIPART take

Technical impact

XAIPART analysis. HERMES and Mercury together turn HF from an essentially analog medium into a file-transfer pipe, which matters for designers who previously had to treat shortwave as voice-only. Engineers evaluating it for remote telemetry, environmental monitoring, or backup SCADA links should focus on the open-source software stack, the 3 to 30 MHz coverage, and the ~20 W power envelope as the design boundaries rather than the headline "long-range" claim.

XAIPART analysis. Because the modem is open source, BOM-level integration is feasible for small teams, but designers should plan for ionospheric variability, antenna selection, and link-budget margins that differ sharply from a 20 W VHF/UHF or cellular module. The 400 to 600 km link range applies to ionospheric skip paths, not line-of-sight deployments.

Market impact

XAIPART analysis. For procurement teams serving NGOs, disaster-response, maritime, and remote-industry customers, HERMES changes the sourcing question from "which HF voice transceiver?" to "which open-source HF data stack and supporting RF front end?" That expands the bill of materials beyond traditional radio suppliers into software-defined radio vendors and antenna/passive-component lines.

XAIPART analysis. Lead-time impact is indirect: HERMES itself is open-source code, but the underlying 20 W HF transceivers, HF-band filters, and ionospheric-aware antenna systems are typically specialty items with longer lead times than mainstream cellular modules. Buyers should expect to qualify multiple RF-component sources rather than treat HF data as a catalog part.

Action

XAIPART analysis. Component buyers supporting NGO or maritime customers should shortlist 20 W-class HF transceivers, broadband HF antennas, and SDR platforms compatible with the Mercury modem, and confirm local amateur-radio encryption rules before specifying encrypted builds. Design engineers should prototype HERMES on standard SDR hardware, characterize real-world throughput versus the "hundreds of bits per second" baseline cited by the source, and document ionospheric worst-case latency for any safety-critical use case.

XAIPART Forecast

XAIPART analysis. XAIPART expects that, within 9 months of this brief (by 2027-07-11), at least one published third-party measurement of the Mercury modem over HERMES-class HF links will report sustained throughput above 1 kilobit per second in field conditions; if no such measurement is published by 2027-07-11, this forecast is wrong. The threshold is traceable to the source's claim that conventional HF digital rates sit in hundreds of bits per second, so "above 1 kbps" represents a meaningful step-change rather than a marginal improvement. XAIPART analysis

Facts are as reported by IEEE Spectrum. The design-in, sourcing, and forward-looking statements above are XAIPART's analysis, not the source's claims. Uncertainty: the source provides no measured throughput figure for HERMES/Mercury in bits per second, no published BOM or transceiver part numbers, and no shipment or user counts beyond the 10 or 11 Bangladesh pilot boats; encryption-capable deployments depend on jurisdiction-specific amateur-radio rules that the source does not enumerate.

Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
