Current packet handling follows ADR-0010: metadata-only surveys. Semantic-message interpretation and content exports have been removed; dated content-related records and screenshots are historical.
OVMeshDR++ is an experimental receive-only RF survey application. Start with the user guide and current capability summary; measurement and protocol references provide the details needed to interpret or extend it.
- User guide: fresh sessions, receiver setup, GPS, recording, analysis and exports.
- Receiver and platform compatibility: HackRF One, RTL-SDR and experimental RAK5146 USB/LBT capabilities, limits and validation status.
- RTL-SDR setup: source selection, sample rates, tuner gain and USB troubleshooting.
- RAK5146 USB/LBT setup: one/two-board selection, scan/profile controls, platform limits and troubleshooting.
- Build and packaging: local builds, dependencies, storage locations and platform limits.
- Linux build setup: local OpenSSL preparation, prerequisites and configure-error troubleshooting.
- Apple Silicon packaging and Ubuntu packaging: package recipes, library/source materials and platform-specific acceptance checks. See current package status before treating a candidate as a release.
- Screenshot gallery: historical synthetic interface examples and separately labeled sample reports.
- Support playbook: troubleshooting and useful diagnostic information.
- Current capabilities and limitations.
- Spectrum measurement specification: frequency bins, thresholds, exposure, occupancy, power, center-guard comparisons and uncertainty.
- Concentrator measurements: one/two-board RSSI histograms, configured packet profiles, timing, GPS, saved sessions and reports; separate from SDR FFT measurements.
- Survey methodology: planning observations and comparing frequency, time and receiver location.
- Data model and retention: recording schemas, compact storage, GPS association and export boundaries.
- RF capability gaps: what the results support and what still needs validation.
- Validation scope: existing test coverage, known limitations and qualification gates.
- Architecture and Meshtastic wire reference.
- RAK5146 HAL provenance: minimal receive-only Semtech source intake, USB transport hardening and scanner interpretation.
- Dependencies and licensing, third-party notices, OpenSSL intake, USB intake and Nanopb intake.
- Security and privacy and test-data provenance.
- Roadmap, development and releases, and source-release checklist.
- Governance and documentation policy.

Implemented behavior, synthetic correctness checks and field qualification are separate. A report or screenshot is not proof of calibrated measurements, exhaustive traffic detection, transmitter identity or regulatory compliance.
RTL-SDR driver intake and license provenance documents the reviewed source and local changes.
