v2.24

2.24 (2025-05-30)

Added

• EiBi schedule support, see https://esp32-si4732.github.io/ats-mini/manual.html#schedule

Fixed

• Reapply Squelch after waking up from CPU Sleep mode. #127

v2.23

2.23 (2025-05-26)

Added

• Ability to select FM de-emphasis setting based on region. #85
• Show MAC-address on the receiver status web page. #114
• Add ALL-CT RDS options for those who prefer precise time over WiFi.
• EEPROM backup/restore via the receiver web interface. Restore only works on compatible firmware versions.
• New optional UI layout with large S-meter and S/N-meter.

Fixed

• Fix the AVC bug, huge thanks to Dave (G8PTN)! #117

v2.22

2.22 (2025-05-23)

Removed

• Removed the Mute menu option. Use short press instead while in the volume adjustment mode.

Added

• Experimental Squelch option based on RSSI threshold. Unlikely to work in SSB mode. To turn it off quickly, short press (>0.5 sec) the encoder button in the Squelch menu mode. #32
• Help screen and system info screen (see Settings->About). The help screen is also displayed on first start.

Changed

• Use short press to delete a memory slot.

Fixed

• Fix restoring memory slots that belong to the bands with the same names. #100

v2.21

2.21 (2025-05-21)

Changed

• Make the Wi-Fi icon a bit more lightweight.

Fixed

• Disable the automatic tuning capacitor. #97
• NTP time synchronization no longer ignores seconds.

v2.20

2.20 (2025-05-18)

Added

• Direct frequency input mode. Press and rotate the encoder to select the step (digit or "half-digit"), rotate the encoder to adjust the frequency, use short press to align frequency to the current step. To exit the mode, click the encoder or wait for a couple of seconds. #26
• Settings->UTC Offset now affects the displayed time (whether it was received from RDS or NTP). #44
• Settings->Scroll Dir. option to reverse the menu scroll direction. #79
• Add SNR to the serial console log.
• Stop the automatic seek process by clicking the encoder button (exit by rotating it still works).
• Use press+rotate for manual fine tuning in Seek mode.
• Wi-Fi mode to sync time over NTP, view the receiver status and Memory slots.

Changed

• Experimental: re-enable automatic antenna capacitor on FM, MW and 160M bands (as it was in 1.06 and earlier), plus reset it when switching between AM bands. #13
• The short press (volume) shortcut is no longer global (now works only in VFO mode) and can be used by menus and other modal modes. #26
• SSB tuning is now aligned to the current step. #76
• Completely silence speaker output on mute. #78
• Decrease RSSI & SNR thresholds in FM/AM seek modes.
• Theme editor can be enabled or disabled via the T terminal command, without recompiling the firmware.

Fixed

• Set seek step according to the current step. #5
• SSB memory slots now store frequencies with 100Hz precision. Serial commands that work with memory slots now expect frequencies in Hz. #79
• Fixed wrong menu titles. #80
• Fix audible clicks when scrolling over empty memory slots.

Improved Documentation

• Add web-based Memory slot edit/backup/restore tool: https://esp32-si4732.github.io/ats-mini/memory.html

v2.14

2.14 (2025-05-06)

Added

• Zoomed menu mode for accessibility purposes (enabled via Settings->Zoom menu). #71
• Serial commands $ and # to backup and restore memory slots.

Changed

• Extended 75M and 90M band boundaries.

v2.13

2.13 (2025-05-01)

Added

• Add Seek menu - automatic scan on AM/FM, faster tuning step on SSB. #26
• CPU sleep mode (light sleep) to reduce the power consumption even more.

Changed

• Increase seek timeout from 8 seconds to 10 minutes.

Fixed

• Get rid of the short display blink that shows some visual garbage at power on.

v2.12

2.12 (2025-04-29)

Removed

• Remove the main menu counter.

Added

• Added RDS radio text, program type, and PI code. Can be enabled via Settings->RDS. #9
• Memory menu to store favorite stations. Press the encoder on an empty slot to store the current frequency and mode, rotate the encoder to select a slot. WARNING: this firmware version resets the receiver settings. #56
• Add I and i hotkeys to tweak the calibration value. Add separate BFO and calibration fields to the remote log. #60
• Add 10kHz step for WFM mode
• Add Settings->Sleep Mode. Controls whether the encoder is locked or not during sleep. Unlocked mode allows tuning (and setting the volume) with less self-induced noise.

Changed

• Remote encoder keys changed. Use R and r to rotate it and e to click.

Fixed

• Get rid of 1M and other AM steps in LSB/USB steps menu #15
• Extend the 25, 31, 41, 49, and 60 meter bands. #50

v2.11

2.11 (2025-04-22)

Added

• Added named frequencies database with FT8 and SSTV frequencies as samples.
• New Magenta color theme

Changed

• Make RDS clock optional, move it to the info panel. To enable it, set Settings->RDS to PS+CT. Also clock is synchronized only once until the receiver or RDS CT is turned on and off (this helps to avoid getting wrong time from incorrectly configured FM stations). WARNING: this firmware resets the receiver settings! #39
• Added DID/DST registers display to About screen.
• Added RGB color bar to About screen.
• Set the default sleep timeout to 0 (disabled)

Fixed

• Use BGR color order on the GC9307 display type #41
• Fixed display of CB channels. #51
• SSB calibration wasn't applied when changing bands or modes. Now it is. #53

v2.10

2.10 (2025-04-18)

Changed

• Move Calibration to the Settings menu
• New bands list: more bands, different names and limits, sorted by modulation type for faster switching. WARNING: this change resets the receiver settings!
• Pixel-wise tuning scale scrolling
• Simplify remote serial output, change encoder keybindings. Use E and e to simulate the encoder rotation, p to push the button.

Fixed

• Fix the screenshot palette. You can use the following oneliner to make a screenshot: echo -n C | socat stdio /dev/cu.usbmodem14401,echo=0,raw | xxd -r -p > /tmp/screenshot.bmp #40
• Autodetect the display type and invert/mirror the picture if needed #41
• Fix SSB band limits checks #46
• Hopefully fix the SSB noise tone issue #46
• The "EEPROM Resetting" screen is not hidden
