Four apps.
One diagnostics folder.

Reviewed family releases · 8 November 2026

Each app keeps its own radio capabilities, original name, version and build. Download the product for your radio.

Logs together, settings by choice

New diagnostics are stored under ~/Library/Application Support/Radio-Utility-Family/LogsEach record identifies its source app and version. Historical logs stay in their existing locations. Radio Family settings can export the new family logs as one ZIP.

Station identity sharing is off by default. Publish from one app, review the source and values in another, then explicitly import. Radio ports, audio routing, power, contacts and transmit permission remain local. Compatible account transfer uses a separate opt-in Keychain control in FX, ICOM and Lab599.

FX and ICOM require Apple Silicon and macOS 14+. Lab599 and Xiegu support Apple Silicon and Intel on macOS 12+. These packages are not Apple notarized. Lab599 retains its pre-release status and signed update feed; Xiegu and ICOM remain development releases. GitHub source access follows the existing repository visibility.

Validation uses synthetic audio, disposable stores and loopback radios. Physical RF timing, USB/audio hardware and cloud-provider behavior require live verification. X6100 CAT restrictions remain in force.
