Fusion 6.1.0 is here ! 🚨
👀 Full Watch
Fusion v6.1.0 adds Full Watch, an extension of dual
watch that can monitor:
VFO A;
VFO B;
priority channel 1;
priority channel 2.
The RxMode menu now provides two additional modes:
FULL RX / RESPOND: monitors all configured channels and replies on the channel that opened the squelch;
MAIN TX / FULL RX : monitors all configured channels but always transmits on the selected main VFO.
Priority channels use the existing scan-list priority settings. Duplicate or unavailable priority channels are ignored automatically.
Animated chevrons show the background watch cycle, and channel navigation now returns cleanly from a temporary priority-channel display.
🔄 Instant configuration-bank switching
The SetCfg menu can now apply another multiboot configuration bank immediately, without restarting the radio or restoring another firmware slot.
Changing banks reloads the complete operating state, including channels, VFOs, scan lists, menu settings, display configuration, and edition-specific settings.
The status bar displays the active bank as CFG M or CFG 1to CFG 4, so the selected configuration remains visible during normal use.
Each firmware slot may therefore use its matching bank, share a bank with another slot, or switch between several independent operating configurations while the same firmware remains active.
📋 Mixed scan lists
The scan-list selector now includes a MIXmode. It lets you choose any combination of the available scan lists and scan them as one set.
The menu displays the number of selected lists, making large channel plans easier to check before starting a scan.
🗃️ Overlay applications
The experimental Labs overlay platform has received its largest update so far.
The number of external-Flash app slots has increased from 8 to 16.
Overlay API v2 adds read-only assets, allowing fonts, text, bitmaps, tables, and other static resources to remain in external Flash instead of consuming the 4 KiB executable overlay.
App settings are preserved when an app is updated, and the firmware now reports code and asset sizes separately.
New applications include:
APRS RX — receives Bell 202 AFSK 1200 AX.25 UI frames, decodes common position formats and Mic-E, displays APRS symbols and RSSI, and keeps a five-frame history;
APRS TX — edits and transmits APRS beacons with callsign, SSID, path, symbol, position, and comment;
SSTV — receives 14 SSTV modes and can transmit the radio's boot logo, including Robot, Martin, Scottie, and PD modes used by ARISS events;
EPIRB 406 — receives and decodes first-generation 406 MHz emergency-beacon messages, including beacon ID, country, protocol, position, and BCH status;
SysInfo — displays detailed firmware, memory, external-Flash, multiboot, and runtime diagnostics;
Spectrum3D — renders a fast scrolling 3D spectrum waterfall;
Minesweeper — a complete minesweeper game with title screen and persistent settings;
Snake — the classic snake game;
Space Impact — a side-scrolling arcade game;
Rapid Roll — a platform arcade game.
Existing apps also received substantial improvements.
Cube3D now offers more shapes, zoom, speed, pause, and wire/solid rendering controls. Plasma, Breakout, Beam, and the shared app runtime use less Flash and RAM.
Important
Overlay apps are intended for the Labs edition. An app must match the overlay ABI and capabilities provided by the installed firmware. Apps built for v6.0.0 may be rejected when they depend on retired services; install the v6.1.0 app files supplied with this release.
Caution
APRS TX, SSTV TX, EPIRB, Beacon, and other transmitting apps must only be used on frequencies, power levels, and modes permitted by your licence and local regulations. Never transmit test signals in the protected 406.0–406.1 MHz distress-beacon band.
🚀 AirCopy and external-Flash tools
The Transfer edition's AirCopy implementation is faster and more capable:
multi-block FSK framing approximately doubles transfer speed;
blocks that are already identical are skipped;
TX and RX selections are validated more strictly;
UART-assisted transfer and complete external-Flash cloning are supported.
Labs also adds external-Flash dump and restore through UV Studio, with CRC32 verification. The radio's device-specific calibration sector remains protected during restore operations.
