- Fixed CW sidetone sometimes dropping the first (occasionally second) element after idle - Prevent Wi-Fi power-save from dropping the CW link or causing stuck transmit - Raspberry Pi now boots to console with on-demand VNC (fewer audio dropouts; fixed Setup timeout on Pi Zero 2W) - Integrated ufw firewall setup into WireGuard configuration (auto-installs and enables even on an unconfigured Pi) - App ports allowed only from LAN and VPN subnets; SSH always allowed to prevent lockout - Bound rigctld to localhost to block unauthorized direct control from the LAN - Added device-path validation (path traversal protection) - Fixed FT-991 / FT-991A break-in (BK-IN) not turning OFF - Changed default WireGuard config filename to WG_Raspi.conf - Pi API version: v3.18

[WireGuard VPN setup improvements] - Fixed API Key setup failing after IP address change during WireGuard configuration - Restored Pi password field (supports Pis where SETUP Pi has not been run) - API Key is now set directly from Python — no sudo dependency on shell scripts [FT8 improvements] - Fixed CQ message appearing only once when sent multiple times - Fixed FT8 decoding stopping after "Update Pi" (SSE reconnect now auto-restarts decoding) - Fixed mfsk-decode alert persisting after SSE reconnect [Raspberry Pi setup improvements] - SETUP Pi completion screen now shows "Run Update Pi next" instructions - Update Pi automatically triggers mfsk-decode build (10–20 min) - Files transferred directly from app bundle via SFTP (removed GitHub dependency) [Pi API update — requires Update Pi] - USB audio initialization now also sets "Master" control to 100% (FT8 TX output improvement) - NOPASSWD rules strengthened (daemon-reload, mkdir, tee added)

Pi Setup (SSH) You can now set up a Raspberry Pi directly from the app. Enter the Pi's IP address, SSH username, and password on the new Pi Setup screen, then tap Run — Hamlib, FastAPI, Direwolf, and mfsk-decode are installed automatically on a freshly imaged Raspberry Pi OS (approximately 5–10 minutes). No terminal required. Works with any SSH username; not limited to the default "pi" account.

### New Features - **QSO Log** - Log contacts instantly from the main screen: callsign, RST sent/received, band, mode, frequency, date/time - POTA / SOTA reference fields for both your station and the other station - ADIF export — share selected QSOs or the full log as an .adi file - Edit previously logged QSOs ### Bug Fixes - **Fixed Pi API version mismatch display**: The "Pi API version mismatch" warning in the About screen was incorrectly showing "3.12 is required" instead of "3.13". This has been corrected. ### Pi API 3.13 (update via "Update" → "Update Pi" in the app) - **FT8 decode depth default changed**: 3 (deep: sync>=0.5, 300 candidates) → 1 (fast: sync>=3.0, 75 candidates). In typical environments, "fast" provides the best balance of speed and accuracy - **mfsk-decode updated to mfsk-core v0.13.0**: Migrated internal FT8/FT4 decode API to the DecodeRequest/on_result pattern for improved decode accuracy and compatibility - **Improved PTT audio transmission stability**: Gracefully handles BrokenPipeError when aplay exits early, preventing crashes during transmission - **Improvements to setup_fastapi_radio.sh**: - `libncurses5-dev` → `libncurses-dev` (correct package name for modern Debian/Ubuntu) - Added `curl` to apt package installs - Rigctl version detection now explicitly checks `/usr/local/bin/rigctl` to avoid false positives when apt version is present - Added rpath to `./configure` to reliably prefer `/usr/local/lib` over apt version of libhamlib - Enhanced Python venv corruption detection and automatic repair - Direwolf binary auto-detection (prefers self-built version, falls back to apt version)

### RTTY receive tuning overhaul - **Spectrum display**: the scrolling waterfall is replaced by a bar graph of the current frame's signal strength (`RttySpectrumView`), so the Mark/Space positions are visible at a glance - **Improved auto-tune**: tracks the Mark/Space tones with hysteresis and falls back to the standard tones (2125/2295 Hz) when the signal disappears - **FIX mode**: long-press the Tune button to stop auto-tune; tap the spectrum to move the decode position (the setting is persisted) - **RX level indicator** added ### RTTY transmit - TX path is now chosen automatically (AFSK audio through the Pi). The serial FSK options were removed from the UI because they competed with the CAT port and took rig control down - TX dial offset (Mark tone, plus the FT-991A's 1000 Hz DATA SHIFT) is applied automatically so the signal lands on the displayed frequency - Transmission is refused while the dial frequency is unknown (e.g. right after a link loss), so nothing goes out without a frequency/mode command - **RTTY disabled in direct CI-V mode**: both RX and TX depend on the Pi's audio path, so the RTTY screen cannot be opened over CI-V ### Connection stability - Detects the "frequency stuck at 0" state left behind by a FastAPI restart on the Pi and automatically re-issues `/radio/open` (rigctld recovery, rate-limited to once per 30 s) - Leaving the RTTY screen (SPK off) no longer stops the Pi RX audio stream (it was cutting audio for other clients connected to the same Pi)

### RTTY Send/Receive Support Added Long-press the FT8 button to open the RTTY screen. - Software AFSK modem (RX: Goertzel-based 2125/2295 Hz demodulation with ITA2 Baudot decode) - TX: AFSK tone generation via AudioTrack with automatic CI-V PTT control - RTTY/RTTYR mode toggle button - Tap frequency display to choose band preset (160m–6m, 2m, 70cm) - Preset message buttons (CQ / RST 599 / TU 73 / QRZ / BK / PSE AGN / DE) - FT8 button caption changed to two-line "FT8 / RTTY" display

### FT4 Waterfall Speed Bug Fix (WiFi CI-V mode) ### Compound Callsign QSO Sequence Support

### FT8 Screen — Numeric ALC / Power Display The FT8 screen now shows numeric percentage values alongside the PO (power output) and ALC meters. - Values update in real time during TX - ALC value continues to be shown in red - Both values reset to 0% automatically when TX ends

[New Feature] - Built-in help screen (About → Help / Manual) View the Japanese/English manual without leaving the app [Fixes] - Fixed a Broken Pipe error that occurred during PTT audio TX (improved stability of the Pi-side audio_tx stream) - Fixed duplicate SOTA spots appearing for the same activator and summit (now shows only the most recent spot per activator/summit) [Pi API Update] - Pi API updated to 3.04. Go to Admin → Update Pi to update your Raspberry Pi (takes ~1 minute).

### Fix: Duplicate SOTA Spots in Display When multiple spots are received for the same callsign and summit, only the latest one is now shown. - Applies to both the SOTA tab in the Memory screen and the SOTA overlay in FT8 view - Fixes the issue where the same station kept appearing multiple times as their frequency was updated ### Fix: Frequency Offset When Changing Modes Fixed a frequency drift issue that occurred when recalling a memory, tapping a SOTA/POTA spot, or responding to an SP2ALERT notification that requires a mode change. - ICOM rigs automatically adjust the VFO frequency by the CW pitch offset when switching modes via CI-V. Sending frequency before mode caused the final VFO to be off by that offset - Changed the command order to **set mode first, then frequency** across all code paths: memory recall, POTA spots, SOTA spots, and SP2ALERT integration

v3.03 [Changes] • SOTA spot fetching now uses the REST API (telnet cluster removed) — spots load reliably every time • SOTA list now shows only the last 2 hours (was 24 hours) — only currently active summits are displayed

(More) to add a new preset or Reset All to defaults User Tab - Swipe to edit or delete user memories POTA Tab (New) - Live POTA (Parks on the Air) spot fetch - Park reference (e.g. JA-0001) shown in bold - Filter by mode, band, program, or free text - Filters saved between sessions - Tap a spot → instantly sets freq, mode & width on your rig SOTA Tab (New) - Live SOTA (Summits on the Air) spot fetch - Summit code (e.g. JA/KN-001) shown in bold - Filter by mode, band, association, or free text - Filters saved between sessions - Tap a spot → instantly sets freq, mode & width on your rig All Spot Tabs - "SSB" spots auto-converted to USB (10 MHz and above) or LSB (below 10 MHz) - Digital modes (FT8, FT4, WSPR, etc.) sent as USB - Default SSB & CW filter widths configurable in Connection Settings Other Changes - MEM button now shows "MEM / SET" on two lines Bug Fix - Fixed spots disappearing when a saved filter value from a previous session no longer exists in the current spot data

What's New in v2.30 [New Features] - Auto-scan button ([Search]) on the connect screen. Discovers Raspberry Pi servers on your local network automatically — no more manually looking up IP addresses. [Improvements] - The app now auto-detects the modes supported by the connected rig and shows only those in the Mode picker. Rig-specific digital modes such as C4FM on the FT-991 or D-STAR on the IC-705 are now selectable. Hamlib "noise" modes (ECSSUSB, FAX, SAM, etc.) are filtered out, keeping the list clean. - FM button cycle adapts automatically to the connected radio: IC-705: FM → D-STAR → FM FT-991A: FM → C4FM → DATA-FM → FM - Profile reliability improvements. - Active profile is now automatically updated when you tap Connect or Open Rig, so your latest settings are always saved. - Fixed a bug where rig and CAT settings were not saved when loading a profile. - APRS stability improvements. - Switching TX Method from Rig Modem to DireWolf now reliably stops the rig's built-in beacon transmitter. - APRS configuration (enabled/disabled, baud rate, etc.) is re-sent to the server every 30 seconds, so settings are automatically restored after a server restart. [Bug Fixes] - Fixed an issue in direct CI-V mode where selecting D-STAR would send USB mode to the rig instead.
