ABOUT

I'm quik - network engineer, video gamer, science junkie and tool builder (dh81-labs on GitLab). I've been around the internet since the late 90s under the handle quikchaos (previously QuiK_ChaoS), mostly lurking in gaming communities, Gentoo forums, photography, and graphic design before shifting back into networking, infrastructure, and system programming.

These days I am learning to develop open-source tools - currently in Rust, but not married to any one language. The SDR projects below are the main focus right now, alongside Deadband - a persistent-universe space strategy game built on a Rust world engine with a Godot 4.6 client. Secure voice network engineering is next.

I also contribute to QX9, a research group exploring decentralized systems and applied signal intelligence geared toward reliable public safety communications (see Other Projects below).

QUIKTOOL TUI

The temporary flagship - ties all the radio libraries into one keyboard-driven terminal dashboard. Built with ratatui + crossterm. Currently untested outside of Windows, but is 95% cross-compatible code. Linux/macOS should be workable with minimal effort. See the status table above for version info, or grab the source at gitlab.com/dh81-labs/quiktool.

quiktool help screen: the ten hub menus with their key bindings, a live sidebar showing local time, weather, solar activity, and moon phase, and the legal disclaimer footer

Menu:

8:Deadbandpersistent-universe space strategy game (proof-of-concept)

Sidebar (always visible):

Local time (PST/PDT) + UTC, DST countdown, moon phase + illumination, planets above/below horizon, zodiac transitions, upcoming holidays (US, CA, AU, GB), radio station / signal / now playing, weather stats (imperial + metric)

Hardware:

- Radio features require an RTL-SDR USB dongle (RTL2832U + R820T/R820T2). ~$30.
- Weather, earthquake, moon/solar, and time sync work without hardware.
Dependency diagram for the 6 DH81 SDR projects (7 workspace crates). quiktool depends on dh81-sdr-rs, nrsc5-rs, wwv-rs, and optionally deadband-world. dh81-sdr-rs depends on nrsc5-rs, noaa-wx-rs, and rtl-sdr-rs. wwv-rs and noaa-wx-rs depend on rtl-sdr-rs. nrsc5-rs depends on rtl-sdr-rs (optional git). dh81-sdr-rs, noaa-wx-rs, and wwv-rs all use shared DSP primitives from dh81-sdr-common, a workspace sub-crate of dh81-sdr-rs. rtl-sdr-rs interfaces with an RTL-SDR USB dongle.

ECOSYSTEM

DH81 projects are part of a broader ecosystem spanning three GitLab organizations. QX9 builds decentralized infrastructure on the Veilid application framework - encrypted storage, PBX, media transport, and HIPAA compliance tooling. Deadband is a persistent-universe space strategy game engine designed for decentralized infrastructure.

DH8120 projects (this page) - SDR, TTS, music, astronomy, space weather, CVE research, device backup
QX912 projects - VNS, PBX/NG911, transport, media, compliance, benchmarks
Deadband2 projects - world engine + Godot 4.6 3D client

See the full ecosystem page for details on all QX9 and Deadband projects.
