Lyra v0.4.6

Hardware / scope: Hermes Lite 2 / 2+ over HPSDR Protocol 1. RX, plus
CW / SSB / AM / DSB / SAM / FM and digital (TCI / VAC) transmit — all voice,
CW, and digital modes transmit.

A connectivity-and-polish release: the installer now sets Lyra up so it
connects without needing administrator rights, radio discovery is more
robust, switching between radios is clearer, and the front-panel controls
read at a glance.

New

Installer — works without admin, no firewall fiddling

The installer now adds the Windows Firewall inbound rules Lyra needs
(UDP for the radio link, TCP for the TCI server), so a normal launch can
see and connect to your HL2 — no more "run as administrator" to get the
radio to talk. The installer also offers an optional, unticked checkbox
to disable Windows' multimedia network throttling (the classic
NetworkThrottlingIndex "gaming" tweak), recommended for glitch-free SDR
audio. It's left in place on uninstall (other HPSDR apps may rely on it).

Add by IP — connect to a radio Discover can't reach

Settings → Hardware → Radio gains a directed unicast probe on
Add by IP: type a radio's address and Lyra reaches out to it directly —
for a fixed-IP HL2, a radio on a different subnet, or a network where
broadcast is blocked. If it answers, the entry shows the real board /
gateware / RX-count instead of "manual"; either way you can Open it.

Changed

Easier multi-radio selection

The radio list is clearer when you run more than one HL2:

  • Double-click a radio to Open it (as well as select-then-Open).
  • The connected radio is shown green and bold in the list, so it's
    obvious which one is live.
  • A one-line hint explains the flow: select → Open (or double-click), and
    Close before switching to another radio.

More robust discovery

Discover now sends the discovery probe to both the limited
broadcast (255.255.255.255) and each adapter's subnet-directed
broadcast (e.g. 10.10.30.255). Some NICs, managed switches, and firewall
configurations pass one form but drop the other — sending both means the
radio is found where it previously wasn't.

Front-panel colour cues

  • Start / Stop button: green when stopped (a click starts you),
    red when running (a click stops you).
  • Connection status: green "Connected to …", red "Disconnected",
    amber "Connecting…/Scanning…" during a connect attempt.
  • The top-toolbar chip strip groups its toggles under labels: TX DSP:,
    CW, RX DSP:, and a new Options: group for CTUN and
    WF-ID (which aren't DSP functions, so they no longer sit under the
    RX DSP label).

Docs

  • User Guide: header section documents the Start/Stop and connection-status
    colours and the labelled chip groups; the Radio section covers
    double-click-to-Open, the connected-radio marker, Add by IP, and the
    dual-broadcast discovery.

Notes

The TX Waterfall ID courtesy feature (callsign rendered as a readable
image in the SSB passband) is a courtesy ID and does not replace your
legal voice or CW identification.
