Info QPMRpanCATweb V0.1: Soft Front Panel Web App for Q900 & PMR-171 by DJ0MZ.

Panadapter + Selected USB|Bluetooth HF CW CAT control under Linux (V|U and voice not tested). No IQ under BT. Open software, no warranty.
Runs under a web server (including local https://localhost), not as a standalone file.
Supported by newer Chromium-based browsers with Web Serial + Web Audio (currently not by Safari, Firefox).
Tip: If the browser blocks serial over file://, for CAT start a local server (e.g. python -m http.server) and open via https://localhost.
Reports and suggestions welcome.
Serial and audio drivers: Linux and Mac may need kernel modules, Windows may need a serial driver.
