Radio & connection

• ✅ HPSDR Protocol 1 discovery (multi-NIC, subnet-directed broadcast) + Add by IP for fixed-IP / cross-subnet radios
• ✅ HPSDR Protocol 2 discovery + live RX/TX on BrickSDR2 and Brick3SDR (DUC I/Q, analog drive, ATT-on-TX, radio mic → modulator); discovery firmware shown as v10.6-style, not “fw v0”. TX DUC follows the VFO after retune (v0.25.15). Brick3 Beta Testing (v0.25.16–0.25.20): MAP ANT/RX chips, Auto Step 0–31, per-band PS pad, TX like BrickSDR2 (no dummy-load arm), SUB second pan, RX2 jack isolate on TX. P1 Brick / P1 ANAN: Discover lists, Open refuses (HL2 TX layout) — flash P2; Brick FPGA help: Anton (linoobs)
• ✅ Keyboard VFO (global arrows: 1 kHz / 10 Hz), startup profile (mode binding → last-used → Default), Tuning Mem left-click after idle (v0.25.15)
• 🚧 ANAN-10 / 10E Protocol 2 — classic Alex; BrickSDR2 TX (on-air, no dummy-load arm). Pick marketed model in Settings (Hermes discovery still defaults to Brick). Boxes that shipped P1 should use a P2 FPGA when they can.
• 🚧 ANAN-100 / 100B / 100D / 200D Protocol 2 — Brick3SDR TX (on-air, independent Enable PA). 100D / 200D: two converters, SUB opens a second panadapter.
• ✅ SUB / RX2 on HL2, BrickSDR2, Brick3SDR, and P2 ANAN — second DDC; orange TUNE A / cyan RX1 vs lime TUNE B / green RX2 overlay; band chips red (RX1) vs green (SUB); Shift+click / right-click hops SUB; off-span ◀ RX2 / RX2 ▶. One ADC (HL2 / Brick2 / 10 / 100): overlay + N2ADR follows RX1. Two ADC (Brick3 / 100D / 200D): SUB pane with own waterfall, band-plan, click-tune, Visuals SUB floor/ceiling (per RX2 band), optional SUB layout recall. SUB and SPLIT are independent. SUB + SPLIT click-tune on the SUB pane moves VFO B only. Diversity is a different mode (below) and turns SUB off.
• ✅ Diversity — two converters, same frequency, phase/gain combine. Not SUB. DIV chip opens the dock; ON arms the mix. Second RF is the RX2 jack (Ext1), not ANT2. Gain −27…+27 dB, phase −180…+180°. Per-band pair (unset band starts at 0 dB / 0°); master on/off is global. Drops while transmitting or while PureSignal is live, and returns on unkey. Confirmed on Brick3SDR; same path on ANAN-100D / 200D. HL2 and BrickSDR2 do not show the chip (one ADC).
• ✅ Band stack — each Ham / BC / 11m chip stores three frequencies. Corner digit 1 / 2 / 3. A click from another band returns the last-used slot and does not skip. Click the band you are already on to step. SUB has its own three. Shift+click and right-click still hop SUB. Solar chips tune VFO A to the current slot and do not step it.
• ✅ Protocol 2 Auto Step — DSP+Audio Step walks ADC pad 0–31 (clip +3 / unwind −1), frozen while keyed. Default off. Brick3 MAP ANT / RX jack chips.
• ✅ SPLIT pile-up — TX on VFO B independent of SUB; gray TX pips; right-click SPLIT 1/5/10 kHz shift; lime TX marker (red on key); ◀ TX / TX ▶ when TX is off-span
• ✅ Multi-radio list, auto-connect to the last radio, installer firewall rules (connect without admin rights)
• ✅ Stale-IP guard (won't freeze trying to reach a radio that moved)
• ✅ Graphics crash ladder (OpenGL → software, MSAA off on software) so a bad GPU driver does not leave Lyra with no window
• ✅ MSAA picker Off / 2× / 4× / 8× (Settings → Visuals; default 4×; restart)
• ✅ Xvtr band chips — RF dial (ten-digit LED, ~2.147 GHz), IF NCO, Disable PA default on; Shift+click SUB hop; right-click slot editor. Band-plan region does not rewrite slot MHz — set RF low/high/LO for your allocation. See User Guide Band panel.
• ✅ HL2 N2ADR / IO board — OC LPF (I2C 0x20) is the Enable N2ADR / IO board checkbox. Filter-board follow is always Protocol 1 TX frequency on I2C 0x1D, not gated on that box. v0.25.20 / #17: a return to a band already on the dial is written again. Leave Band Volts on J3 off unless the amp is on the fan header.

Receive (RX)

• ✅ Full WDSP receive chain — USB / LSB / CW / AM / SAM / DSB / FM / DIGU / DIGL / SPEC
• ✅ Per-mode filters, AGC (Fast/Med/Slow/Long/Auto), NR (EMNR 1–4) or NNR (WDSP 2.10 neural; Standard default, Premium optional, mask −10…−50 dB, default −40), exclusive vs each other; noise blanker, auto-notch (ANF), LMS, all-mode squelch
• ✅ 8-band RX parametric EQ (draggable curve)
• ✅ Captured-noise profile (NR-C) — grab your band noise and subtract it (IQ-domain; panadapter stays on uncleaned IQ so a strong station stays rectangular; Floor default −24 dB; can run with NR or NNR; last profile restores on restart)
• ✅ Centre-tune (CTUN) — drag the marker onto a signal while the LO stays put
• ✅ RIT and XIT (receiver / transmitter incremental tuning)
• ✅ Zero-beat markers — Kenwood-style ± needle to dead-tune a CW / AM / SAM / FM carrier by eye
• ✅ Audio out the HL2 codec jack (AK4951) or a PC sound device

Transmit (TX)

• ✅ SSB (USB / LSB), AM (proper carrier + both sidebands), SAM, DSB (suppressed carrier), FM (deviation / pre-emphasis / CTCSS / Region-1 1750 Hz TX burst while keyed)
• ✅ CW — internal iambic keyer (paddle / straight key), keyboard send, CWX, contest macro bank ({CALL}/{RST}/{NAME}…), QSK / semi / manual break-in, adjustable sidetone
• ✅ Digital via TCI and VAC1 / VAC2 — WSJT-X / MSHV / JTDX / FLDigi / VarAC, or a logger on a second cable. VAC Enable is RX; Mic source = VAC1 or VAC2 is TX. VAC2 carries RX2 (turn SUB on). TCI audio and VAC TX are mutually exclusive.
• ✅ TX power / drive, separate tune drive, AM carrier level, mic gain + 20 dB mic boost; Protocol 2 uses analog drive (HP [345]) plus per-band PA Gain / Full Output / CAP, including a dedicated 11m slot
• ✅ Separate RX and TX filter lows (current build) — RX lo under RX BW, TX lo under TX BW on the Filters dock (also Settings → Audio). 0–500 Hz. The lock keeps them equal; unlock and a profile can hold different lows. Older profiles copy the old shared low onto both sides.
• ✅ Always-on ALC + operator Leveler, PHROT phase rotator
• ✅ PureSignal — adaptive TX predistortion (HL2 / HL2+ coupler mod; BrickSDR2 ADC0 pad; Brick3 rear PS jack). Compact dock: ON / 2-tone / Voice / ATT / FB / Reset. Engine chips (st / cal / D0 / D1) on Amp View. Auto-att persisted per TX band (v0.25.16). Attestation in Settings → TX (default off).
• ✅ Waterfall callsign ID — paints your call in the SSB passband (ham bands only)

Native TX audio rack (studio-in-the-radio)

• ✅ 8-band parametric EQ with draggable curve + live RTA
• ✅ 5-band Combinator (multiband compressor — Lyra’s CFC equivalent)
• ✅ Plate reverb for ESSB "air"
• ✅ Speech processing — formant boost, sibilance/consonant emphasis, DX cut-through, de-esser, auto-AGC
• ✅ Voice keyer (message memory) + VOX (with anti-VOX)
• ✅ TX profiles — save/recall the whole chain (including VAC1 and VAC2 knobs; audio device names stay global); a profile can even launch its companion app (VarAC / MSHV / WSJT-X). Startup: mode-family binding → last-used → Default (v0.25.15). How to build one: in-app Help → How to create a profile.
• ✅ Hot-mic monitor / SSB sidetone, separate monitor output device

Metering & TX safety

• ✅ Multimeter — PO / SWR / MIC / COMP / ALC / PA current. The PWR needle keeps the loudest coupler sample between ticks so voice peaks land on the scale (factory peak-hold 700 ms if you have not saved your own)
• ✅ ATT-on-TX RX-front-end protection · RX2 jack isolate on TX (two-converter radios, default on) · TR-sequencing for amp hot-switch safety
• ✅ SWR protection (auto-cut above threshold) · max power / drive cap for low-drive amps
• ✅ TX time-out · hard External TX Inhibit

Panadapter, waterfall & UI

• ✅ Vulkan / RHI scene-graph spectrum — glassy fill/glow, peak-hold, noise-floor line, palettes
• ✅ Click / drag / wheel tuning; draggable passband edges; click-to-tune on the waterfall; collapsible waterfall
• ✅ Dockable UI — snap to edge / split / tab / float, four named layout slots + factory default, lock panels; optional SUB layout recall (Visuals) that restores the pre-SUB arrangement when SUB goes off
• ✅ Windows per-app mixer volume remembered across Stop / Start (v0.25.17; Issue #18 — Stop no longer slams the mixer to 100 % / unmute)
• ✅ 11 m / CB channel chips on the SUB pane — click-tune mode follows Hardware Region (v0.25.18)
• ✅ Crash-safe graphics — auto-steps down to a safer backend if a launch ever fails; an operator-pinned Vulkan/D3D/OpenGL choice in Settings is not overridden by that ladder (v0.24.5)
• ✅ Band switching + per-band memory; GEN / time-station / 20-slot memory bank; EiBi shortwave overlay

Tools & extras

• ✅ RX CW decoder — prints what it hears on-screen
• ✅ DX spots — cluster / RBN / TCI sources, filters, panadapter overlay, click-to-tune
• ✅ Tuner memory — manual-ATU settings per band and per antenna
• ✅ Frequency calibration against WWV / time stations
• ✅ Session recorder — RX audio on Protocol 1 and Protocol 2 + timed panadapter snapshots (Vulkan-safe) → a synced MP4; default folder %USERPROFILE%\Lyra\Recordings (v0.25.12, never Program Files)
• ✅ CAT / Serial — Kenwood TS-480/2000 CAT over COM/TCP, serial PTT input, Winkeyer
• ✅ TCI server — two channels; vfo:0,1 = SPLIT VFO B, vfo:1,0 / dds:1 = SUB; RX1 + RX2 S-meter sensors; CW terminal (key line stays up between letters; callsign correct mid-send) and TX sensors that keep reporting at receive; handshake sends start only when the radio session is running (otherwise stop then ready); STOP never closes the radio and never drops MOX (echoes start while live so WSJT-X / JTDX stay attached and can key); TUNE keys the host TUN path, TRX keys MOX, CHRONO TX-audio headers use the negotiated rate / samples / format / channels (v0.25.14; MSHV / WSJT-X / JTDX / SDRLogger+); SDRLogger+ Combo (call/name/RST from RX1 + one-click log); Lyra Remote voice session (password proof, then that browser's microphone) and a fifth TX-sensor number, ALC headroom (v0.25.21)
• ✅ USB-BCD band data for linear-amp band switching
• ✅ Backup & Restore — export config, dated snapshots (survive reinstall), selective restore
• ✅ Solar / propagation panel (band chips tune VFO A to that band's current stored frequency; they do not step the 1 / 2 / 3 stack), weather alerts
• ✅ Apps — named shortcuts for third-party programs; Tested with and recommended links (Open SSTV, MSHV / WSJT-X, VarAC, midi2tci); auto-start after Hardware Startup (default off)
• ✅ USB encoder (HID wheel) — Settings → Hardware → Navigation (Windows); tunes the focused VFO by the Tuning Step
• ✅ MIDI via TCI sidecar — not native MIDI; Browse an operator-installed MIDI→TCI program under Settings → Apps (default TCI port 40001)

Not yet — see the Roadmap 🗺️

• 🚧 ANAN-G2 / G2-1K — Saturn BPF; TX still dummy-load arm until on-air validated. ANAN-10…200D already use Brick2 / Brick3 TX (see above).
• 🗺️ ANAN-7000DLE / 8000 — OrionMkII BPF / PA not in this pass
• 🗺️ Linux, then macOS
