ATS Mini V4 Menu & Settings Deep Dive: Every Option Explained

A Note on Firmware Variance

Exact menu structure differs somewhat between stock AMNVOLT firmware, the community esp32-si4732/ats-mini fork, and H.J. Berndt's version — this guide covers the general categories of settings you'll find across most firmware versions, since the specific menu path can shift between firmware releases as features get added.

Band & Mode Selection

The core function — switching between FM, AM (MW/LW), and SW bands, plus SSB modes (LSB/USB) within SW. Most firmware exposes a dedicated band-select control (often the main encoder button or a specific menu entry) separate from the tuning encoder itself.

Seek / Scan

Automatic station-finding — Seek stops at the next active signal above a threshold; Scan (in newer community firmware) does a fuller sweep, useful for surveying band activity rather than just landing on the first strong signal. Community firmware has refined this over several releases — check current changelog notes if seek sensitivity or scan behavior seems off compared to what you expected from older documentation.

Memory Slots

Store favorite frequencies for one-touch recall — press the encoder on an empty slot to save the current frequency/mode, rotate to select a slot to recall it. Slot count has increased across firmware versions (32 slots in earlier versions, up to 64 in some newer builds like the Berndt version) — check your specific firmware's current capacity.

RDS (FM)

Radio Data System decoding for FM broadcast — station name, program type, and radio text display when receiving an RDS-capable FM station. Toggle-able in settings on firmware versions that support it; adds genuine information display value on stations that broadcast RDS data.

AGC / ATT / Squelch

Automatic Gain Control and Attenuator settings directly affect how the receiver handles strong vs weak signals — worth experimenting with on a crowded band (see the SSB guide's note on this). Squelch settings (some firmware lets you choose RSSI or SNR-based squelch) control when the receiver mutes on weak/no signal rather than passing through noise.

WiFi & Network Features (Community Firmware)

Newer community firmware builds add WiFi connectivity for things like downloading an EiBi shortwave schedule database directly to the device, and a web-based UI accessible via the receiver's IP address or the atsmini.local mDNS name on your network — genuinely useful for browsing/editing memory slots from a full-size screen rather than the receiver's small display.

Bluetooth (Experimental, Newer Firmware)

Some recent firmware builds add experimental Bluetooth LE control — either an ad-hoc remote-control protocol or HID mode for connecting supported Bluetooth remotes/keyboards to control tuning. Flagged as experimental/potentially unstable in the firmware's own release notes — worth trying but don't be surprised by rough edges if you enable it.

Zoomed Menu Mode

An accessibility-focused display mode enlarging menu text/UI elements — worth enabling if the stock 1.9" display's default text size is hard to read comfortably.

Where to Check Current Exact Menu Paths

Given how actively this firmware ecosystem is developed, the official documentation site's manual page for whichever firmware you're running is the authoritative source for exact current menu structure — treat this guide as a conceptual map of what exists, not a pixel-precise walkthrough that will exactly match every firmware version's menu tree.
