FobosAPP 4.6.2 Android zoom slider

Android-only update.

Changes:

• Added a spectrum/waterfall zoom slider to the Android client.
• Portrait: horizontal zoom slider at the bottom of the screen.
• Landscape: vertical zoom slider at the right edge.
• Slider and pinch zoom stay synchronized.
• Zoom level is persisted across app restarts and orientation changes.

Assets:

• Android debug APK for direct testing.
• Unsigned release APK for signing/repackaging.
• Android source snapshot for this release.

FobosAPP 4.6.1

FobosAPP 4.6.1

FobosAPP 4.6.1 is a stability and usability patch over 4.6.0.

Highlights:

• Added spectrum-frame recording and replay tools for short-lived RF events.
• Improved replay audio/video synchronization and full-IQ replay demodulation.
• Added replay-side tuning controls and cleaned up duplicated replay paths.
• Continued HF interference lab work with baseline visual flattening, reset controls, and audio-side impulse blanking/cancel experiments.
• Improved spectrum/waterfall navigation: changing the listening marker no longer recenters the view, and the waterfall/spectrum view can be panned horizontally.
• Fixed live spectrum update logic that could pull the visible range back to the listening marker.
• Updated Raspberry source packaging without requiring a zip archive.

Privacy/package notes:

• Release packages exclude local FobosAPP.ini, diagnostic logs, raw recordings, IQ captures, NMEA/UBX dumps, WAV files, CSV files, and local backup executables.
• GNSS raw logs and QTH/map-provider keys remain local user data and should be backed up separately before replacing a runtime folder.

FobosAPP 4.6.0

FobosAPP 4.6.0

Research replay, HF lab, and desktop/Raspberry maintenance release over 4.5.2.

Highlights

• Adds Spectrum Frame Recorder with rolling prebuffer capture and a replay viewer for post-event spectrum analysis.
• Adds Channel IQ and Full IQ replay audio paths, including local frequency selection for Full IQ replay.
• Adds shared IQ channelizer helpers used by live processing and replay paths.
• Improves replay UI layout, translations, palette/contrast controls, zoom handling, and large-record playback behavior.
• Extends HF Interference Lab with manual baseline-style cleanup tools for HF noise and interference experiments.
• Keeps network receiver-list behavior and remote/server handling from 4.5.2.
• Keeps Raspberry/Linux source packaging current with the same desktop source files and CMake targets.

Assets

• FobosAPP-v4.6.0-windows-x64.zip - Windows desktop runtime.
• FobosAPP-v4.6.0-raspberry-source.zip - Raspberry/Linux source package.
• FobosAPP-v4.6.0-SHA256SUMS.txt - SHA256 checksums.

Notes

Android is not rebuilt for this release. Local settings, diagnostic logs, SDR recordings, GNSS raw logs, map keys and user coordinates are intentionally excluded from release archives.

FobosAPP 4.5.2

FobosAPP 4.5.2

Network and Android maintenance release over 4.5.1.

Highlights

• Network clients now use the receiver list reported by the server instead of sending a local receiver index to the server.
• Server state and remote refresh avoid extra USB device probing during network handshakes.
• Network audio playback, relay and HTTP output now work when a client attaches to an already-running server.
• Fixed a network-client close hang caused by waiting for a local SDR reader in client-only mode.
• Updated the Android USB/network client with Fobos/RTL target auto-sync, corrected sample-rate option switching, and spectrum half-swap handling.

Assets

• FobosAPP-v4.5.2-windows-x64.zip - Windows desktop runtime.
• FobosAPP-v4.5.2-raspberry-source.zip - Raspberry/Linux source package.
• FobosAPP-v4.5.2-android-usb-network-debugkey.apk - Android USB/network client debug-key APK.
• FobosAPP-v4.5.2-SHA256SUMS.txt - SHA256 checksums.

Notes

The Android APK was rebuilt on a separate Android toolchain. The repository source is bumped to 4.5.2-usb-network for future Android builds.

FobosAPP 4.5.1

FobosAPP 4.5.1

FobosAPP 4.5.1 is a privacy, stability, packaging, and waterfall-visual patch
over 4.5.0.

Highlights

• Restores the useful legacy waterfall contrast/palette behavior while keeping
  the optimized low-copy waterfall row path.
• Removes exact latitude/longitude from automatic GNSS IQ sidecar metadata,
  acquisition reports, and UBX verbose diagnostics. GNSS reports keep QTH
  locator context and an explicit privacy note instead.
• Tightens release packaging so nested recordings folders, local logs, raw
  captures, GNSS reports, local settings, tokens, API keys, and scratch files do
  not enter release archives.
• Cleans the roadmap into a current live plan instead of a historical task log.
• Keeps the large source split/refactor work current for desktop and Raspberry
  source builds.

Known Status

• Fobos Standard and Fobos Agile remain the primary supported paths.
• RTL-SDR remains a secondary/test backend.
• Serial GNSS modules through NMEA/UBX are the practical GNSS path.
• SDR-only GNSS acquisition remains experimental.
• DMR voice and external DMR decoder bridges remain lab features.
• Android was not rebuilt for this patch.

Privacy Note

FobosAPP.ini is local user data. It may contain QTH coordinates, map API keys,
DMR privacy keys, serial ports, presets, and UI settings. Keep or export it
before replacing a runtime folder, but do not publish it with release packages.

FobosAPP 4.5.0

FobosAPP 4.5.0

This release focuses on GNSS/QTH work and keeps the current DMR lab backends
available for testing.

Highlights

• Practical external serial GNSS support: NMEA live position, time, satellite
  table, sky view, QTH map overlay and per-satellite/system filters.
• u-blox/NEO-M8N-tested UBX workflow: enable NAV messages, poll/apply
  CFG-GNSS, save configuration with CFG-CFG, and capture raw UBX/NMEA
  binary logs.
• SDR GPS L1 C/A diagnostics improvements: IQ monitor, acquisition reports,
  weak/no-lock summaries, DC cleanup and tone-notch diagnostics.
• Reduced normal diagnostic-log noise; frequent GNSS telemetry is now reserved
  for verbose logging.
• Native RTL-SDR defaults to auto gain/AGC.

Runtime Package Notes

The Windows x64 zip is intended to run from its unpacked folder. It includes
runtime DLLs that can be redistributed with the app, including Qt, FFTW, Fobos,
RTL-SDR, bladeRF beta runtime files, and optional DMR bridge tools where their
licenses allow redistribution.

Optional AMBE/DMR voice functionality remains experimental. See
README.md, THIRD_PARTY_LICENSES.txt, licenses/dmr_voice_backend/, and
config/dmr_backends.example.json in the package for the backend contract and
for instructions on fetching/building optional dependencies such as
mbelib-neo or OpenDMR/softdmr when they are not bundled in a specific build.

The package intentionally excludes local settings, diagnostic logs, raw GNSS
serial captures, SDR IQ recordings, screenshots and user test data.

Known Issues

• SDR-only GPS position lock is not yet proven with the tested antenna setup.
  Use an external serial GNSS module for practical positioning.
• DMR voice is still lab quality. mbelib/OpenDMR, DSD-neo and GopherTrunk paths
  are comparison and debugging routes.
• Some Fobos Agile hardware/firmware/host combinations may show center-
  frequency placement or I/Q mirror issues during tuning. This remains under
  hardware/vendor investigation.

FobosAPP 4.4.0

FobosAPP 4.4.0 publishes the current DMR and GNSS work as a practical test release.

Highlights:

• DMR backend selector for FobosAPP+mbelib, FobosAPP+OpenDMR/OP25-compatible path, DSD-neo, and the experimental GopherTrunk bridge.
• DMR channel-rate controls and metadata stability improvements.
• Live USB/serial NMEA GNSS support via Qt SerialPort, tested with a u-blox/NEO-M8N-style receiver on COM4.
• GPS/QTH map updates from valid NMEA GGA/RMC fixes.
• QTH privacy controls: clear current real location, stop NMEA reception on request, hide the green current-location marker, and remove test/search markers with right-click.
• Windows runtime now includes Qt5SerialPort.dll.

Known issue:

• Some Fobos/Agile receivers or host/firmware combinations may still show intermittent center-frequency placement, shifted spectrum, or I/Q mirroring after tuning. The attempted startup frequency jog was removed because it could make the shifted state persistent. This remains under investigation and is not marked as fully fixed in 4.4.0.

Package notes:

• The Windows x64 zip is the main ready-to-run package.
• The Raspberry/source zip is included for Linux/Raspberry builds.
• Android was not rebuilt for this release because these changes are desktop/runtime focused.

FobosAPP 4.3.2 beta

FobosAPP 4.3.2-beta

This beta adds experimental native bladeRF RX support without SoapySDR.

Added

• Native bladeRF RX backend using runtime-loaded Nuand libbladeRF.
• Windows beta package includes Nuand 2025.10 bladeRF runtime files under bladerf/.
• SC16_Q11 bladeRF IQ conversion into the existing FobosAPP float-IQ pipeline.
• bladeRF device enumeration, open/configure/start, live center retune, and Standard scan compatibility.
• Optional detailed [bladeRF] RX stats logging when verbose logging is enabled.

Bundled Third-Party Runtime

• bladerf/bladeRF.dll from Nuand bladeRF 2025.10 Windows installer.
• bladerf/libusb-1.0.dll from the same installer.
• License notices are included in bladerf/.

Scope

• RX-only.
• Untested locally without bladeRF hardware.
• TX/PTT support is intentionally not enabled; it remains planned for a separate transmitter backend safety architecture.
• Android APK is not included or updated for this beta.

Validation

• Built Windows Release with MSVC/CMake.
• Verified bladeRF.dll exports the required symbols.
• Verified bladeRF.dll dependencies; only bundled libusb plus the existing VC runtime are needed.
• Packaged Windows x64 and Raspberry/source archives.
• Checked Windows ZIP does not include installer payloads, logs, recordings, token files, INI files, or IQ/WAV captures.

FobosAPP 4.3.1

FobosAPP 4.3.1

This is a focused Agile scan visualization hotfix release.

Changed

• Agile scan IQ blocks now carry scan-point metadata from the receiver callback through IqBuffer and FFT processing.
• Scan visual modes now use the scan center that produced the IQ block instead of querying the receiver later from the UI/spectrum update path.
• The scan visual mode selector now sits above the scan controls because it applies to the whole scan visualization, not only Agile scan.

Fixed

• Fixed irregular Agile scan waterfall sector placement caused by stale or unrelated scan indices.
• Skipped Agile tuning-period buffers (scan_index == -1) so transitional IQ is not drawn as a valid scan row.
• Improved Floating/True axis and Pass composite scan visual stability.

Notes

• Android APK is unchanged from 4.3.0 and is not re-uploaded for this desktop/source hotfix.
• DMR and GNSS remain experimental laboratory features.

Validation

• Built Windows Release with MSVC/CMake.
• Deployed to release/bin.
• Packaged Windows x64 and Raspberry/Linux source archives.
• Local Agile scan test at 60-120 MHz, 20 MHz step showed ScanVisualDebug metadata alignment with badRows=0 across 240 diagnostic rows.

FobosAPP 4.3.0

FobosAPP 4.3.0

This release continues the 4.x receiver-backend work and cleans the public release packages.
