Advanced FT8/FT4 DX Decoder 1.0.25

Advanced FT8/FT4 DX Decoder now supports both SDR++ and SDR++Brown on Apple Silicon macOS.

Download the DMG, open Install Advanced FT8-FT4 DX Decoder, select your radio application and click Install. The installer detects installed hosts, prepares first-run settings when needed, offers an optional home locator, preserves settings and logs, and saves a backup. It uses the matching binary for each host. No Python or Terminal is needed.

The installer and DMG are signed with Developer ID and notarized by Apple. The ZIP contains the same installer. Brown keeps its existing native integration. Standard SDR++ uses standard host APIs, independent location settings and bundled country-prefix data.

Supported hosts: SDR++ 1.2.0, May 28, 2024 build and SDR++Brown 1.2.1, August 4, 2026 build. macOS 15+; tested on macOS 26. Other host builds may need a matching plugin build. The installer checks the selected host automatically.

Set the home locator in the installer, in Brown's Source > My Grid, or in standard SDR++'s plugin Settings > General > Maidenhead grid. The README and installation guide include the steps.

Verified live FT8 reception in standard SDR++. Both builds passed 10 native checks; the shared code passed the address/undefined-behavior sanitizer checks. Synthetic FT8/FT4 decoding and 12 isolated installer safety scenarios passed. Payload checksums, code signatures, notarization tickets and Gatekeeper acceptance were verified.
