RDR v2.6.0

RDR 2.6.0 stable for Windows x64 and Linux x64. Existing HQ2RDR data directories and installer filenames remain compatible.

• CQ WW SSB scoring adds per-band totals, zone/country multipliers, contest-specific duplicate checks, multiplier hints in Cluster/Band Map, last-QSO score gains and received-zone entry focus.
• Cloud Sync preserves logbook type and every contest setting across devices, including empty logbooks and configuration edits without new QSOs. Apply supabase_logbook_contest_safe.sql before using metadata sync, then first sync the device holding the complete contest configuration.
• Logging adds ADIF import confirmation, preserves digital submodes, receives digital auto-log UDP broadcasts and optionally filters worked stations while entering a callsign.
• Station Control improves radio selection, meter stability, peak display, FT-710 TX bandwidth controls and CAT diagnostics. DX Cluster connects automatically at startup.
• Band Map improves station/frequency alignment, source grouping, scroll behavior and tuning from the frequency axis. Maps/Globe add solar gray line, corrected band/mode filters and collapsible filter panels.
• QRZ receives compact browser navigation, search, zoom, QSO follow/pin controls and a collapsible contact summary. LoTW preserves confirmations, and Club Log adds ADIF batch uploads.
• Audio supports RX audio in stereo QSO recordings. Net control adds a floating operator view and Excel/PDF exports. The app now uses the RDR name while retaining compatible data directories and installer filenames.

Downloads: use the Windows Setup EXE or unpack the Linux ZIP and follow its included README.

Cloud administrators: apply supabase_logbook_contest_safe.sql before metadata synchronization. Start with the device holding the complete contest configuration, then sync the other updated devices. Existing QSOs are retained.
