FM/AM Radio (TEF6686_ESP32)

Version: 2.20-A002 | Published by Attaky

FM/AM Radio ESP32 Standard Cell

A full-band FM and AM receiver for Attaky Core, with touch tuning, live signal readouts, and optional Wi-Fi extras.

FM/AM Radio turns Attaky Core plus the FM/AM Radio module into a full-band broadcast receiver with a large touchscreen and a high-performance receiver front end. Tune local broadcasts, save favourite stations, and read signal details from a clear on-device interface built for everyday listening and FM-DX exploration.

Highlights

  • Full-band FM and AM reception: Listen across the broadcast bands with a high-performance receiver front end.
  • Touchscreen tuning: Enter a frequency, step through the band, and store favourite stations from a large, clear touchscreen.
  • FM broadcast data: View RDS station name, radio text, and other available broadcast data where supported by the station.
  • Live signal readouts: See signal strength, S-meter and dBµV readings, stereo or mono status, bandwidth, and tuning information.
  • Optional Wi-Fi features: Use the on-device Wi-Fi setup portal to enable time sync and upstream community FM-DX tools when desired.
  • Modular Attaky hardware: Run it on Attaky Core with the FM/AM Radio module, then add the battery module for portable listening.

Tuning by touch

Use the large touchscreen as the main tuner. Dial in a frequency directly, move through FM or AM in steps, and keep favourite stations close for quick return listening. The interface is built around clear frequency controls, so the radio can move between casual listening and precise tuning without extra equipment.

Reading the signal

FM/AM Radio shows more than audio. Live readouts display signal strength in S-meter and dBµV, stereo or mono status, bandwidth, and tuning information. On FM broadcasts with RDS, the screen can show station name, radio text, and other broadcast data when available.

Optional Wi-Fi extras

Network features are optional. The on-device Wi-Fi setup portal can enable time sync and upstream community FM-DX tools, including reception-spot submission, when configured. Leave Wi-Fi unconfigured and those network features stay off.

Everyday controls

The interface exposes practical radio and display settings for audio, RDS, FM and AM band behaviour, connectivity, FM-DX, auto memory, brightness, theme, language, clock display, screensaver, battery indication, signal-meter unit, and frequency font. The result is a receiver that can be adjusted for the way the broadcast sounds, the way the screen reads, and the way the radio is used.

Compatibility

FM/AM Radio requires Attaky Core paired with the FM/AM Radio module for reception. A bare Attaky Core can boot the app, but there is no tuner without the radio module installed. Add the battery module for portable use away from a fixed power source.

Known limitations

The upstream project serves the amateur-radio and FM-DX community, so some screens retain ham and DX terminology plus optional community tools such as reception-spot submission. Those network tools are optional and off unless configured. Full reception functionality requires the FM/AM Radio module.

Upstream and license

FM/AM Radio is a port by Attaky of the open-source project TEF6686_ESP32 by PE5PVB to Attaky modular hardware. The project is licensed GPL-3.0, and corresponding source is published per the license. Upstream authorship and the GPL-3.0 license are retained, with thanks to the upstream author.

Release Notes
What's new
- Rebuilt as a clean port of the upstream v2.20 release onto a self-contained Attaky board layer, so future upstream updates carry over with far less rework.
- Touch-first tuning: type a frequency on the on-screen keypad, pick a band from a popup, seek up or down, and step through stored presets from the touchscreen.
- On-screen menu button, so settings are reachable directly by touch.
- Physical keys mapped for the Attaky keypad: up and down set volume with auto-repeat, the power key toggles the screen, select opens and closes the menu and cancels a running FM DX scan, the side keys seek, and right switches band.
- Battery level shown as a 4-segment icon with a voltage readout when the battery module is fitted.
- Screensaver on an idle timer, plus a light standby that blanks the display while audio keeps playing.
- Volume adjustable down to -60 dB in 1 dB steps for finer low-level listening.
- Brightness set in the menu is applied at boot.

Known limitations
- The automatic memory scan does not store presets in this version.
- A logbook entry cannot be written manually from the device; automatic logging during an FM DX scan is unaffected.
- Installing this version resets stored settings.
