ATS Mini — Custom Fork

This project is a custom firmware fork for the ATS-Mini radio.
It keeps upstream ATS-Mini behavior and adds practical quality-of-life improvements for daily listening.

What This Fork Adds

• Signal Scale view: an extra screen layout that gives a quick visual sense of activity across nearby frequencies.
• Band-map hints: color cues on the scale to help distinguish broadcast and amateur segments.
• Web Control (web-control branch): control the radio from a phone or computer at http://atsmini.local/control.
• General usability/performance improvements: smoother interaction and faster startup behavior.
• Piggy mascot: small visual element in the UI.

Branch Guide

• main: stable custom UI/features without web control.
• web-control: includes everything from main plus browser-based remote control.
• waterfall-experiment: experimental/legacy branch, not actively maintained.

main

Tracks upstream with the following additions:

• Signal Scale layout — A third UI layout option (alongside Default and S-Meter) that replaces the bottom frequency scale with signal strength markers from scan data.
• Band-map line — quick visual cues for broadcast and amateur segments.
• Piggy mascot — small branding element in the main UI.

web-control — Web control + performance improvements

Includes everything from main, plus:

• Browser-based remote control UI at http://atsmini.local/control (or device IP).
• Live status updates in the page, so meters and radio state track changes in near real time.
• Full day-to-day controls from the browser, including:
  • tuning and seek
  • band and mode changes
  • volume, squelch, AGC/AVC, mute
  • memory tune/store/clear
  • scan start/stop and scan data view
  • RDS mode switching
• Improved startup flow so the radio feels ready faster and network tasks are less intrusive.
• Smoother interaction under load, with better responsiveness while using both hardware controls and web controls.
• General stability/performance cleanup focused on long-running everyday use.

Getting Started

1. Flash firmware using the upstream ATS-Mini flashing guide.
2. Choose your branch (main or web-control) based on your use case.
3. If using web-control, configure Wi-Fi on the radio and open http://atsmini.local/control. If mDNS does not resolve, use the radio's IP address instead.
