Repeater Controller Features and Settings (October 2, 2026)
Repeater Controller Touchscreen Display
Standby (STATE: IDLE)
The controller is waiting for an incoming signal. The display shows the current TOT, HANG, CW ID, and other settings.
Repeater controller display and example settings
Repeating an Incoming Signal (STATE: TX)An incoming signal has been detected on the receiver (uplink), and the transmitter (downlink) PTT is activated to relay it.

Repeater controller display and example settings
Transmit Hold (STATE: HANG) Transmission continues for the configured HANG time after the received signal ends. If another signal arrives during this period, normal repeating resumes.
Repeater controller display and example settings
Transmitting a CW IDThe configured message, such as your call sign, is transmitted in Morse code.

Repeater controller display and example settings
Transmitting a Voice ID The DFPlayer plays audio files for the time signal, spoken time, and call sign.
Sample audio files are provided. Prepare suitable recordings for your own station.
 
Repeater controller display and example settings
TOT (Time-Out Timer): Limiting Continuous TransmissionWhen the time limit is reached, transmission stops and the controller enters TOT lockout.
The controller returns to standby after the receive input remains inactive for the TOT_LOCK period.
 
Repeater controller display and example settings
Settings Screen Tap an item while the controller is idle to edit it. The selected item turns red. Use [-] and [+] to change the value, then tap [OK] to save.
Repeater operation is suspended while editing settings on the touchscreen.
TOT: Continuous transmission limit, adjustable from 1 to 30 minutes.
 
Repeater controller display and example settings
Transmit Hold Time (HANG) The transmit hold time after reception ends can be set from 0 to 30 seconds.
 
Repeater controller display and example settings
CW ID Interval Select OFF, 1 minute (for testing), or 5, 10, 15, 30, or 60 minutes.
The firmware suppresses CW at minute 00 to give priority to voice ID.
Check the actual transmission timing on your controller when using the 60-minute setting.
 
Repeater controller display and example settings
CW MODE
   Choose MODE A or MODE B for CW ID transmission.
 MODE A After the configured CW interval has elapsed, a CW ID is transmitted in response to repeater access.
 MODE B CW IDs are transmitted periodically using the RTC clock, CW interval, and CWID_START settings.  

Repeater controller display and example settings
 
Receive Signal Qualification Time (SQL HOLD) The receive input must remain active for this period before transmission starts. This helps prevent brief noise bursts from triggering unwanted transmissions.
On the touchscreen, this can be set from 0 to 5.0 seconds in 0.1-second steps.
In the PC settings editor, SQL_STABLE uses units of 100 ms: for example, 3 means 0.3 seconds and 50 means 5.0 seconds.
Repeater controller display and example settings
 
Editing the CW ID MessageUse the left and right arrows to select a position, and [-] and [+] to change the character. [INS] inserts a space and [DEL] deletes a character.
Tap [OK] to save or [C] to cancel. Enter up to 19 characters using uppercase letters, digits, spaces, and /.
Repeater controller display and example settings
 
Repeater Controller PC Settings Use the Windows settings editor Repeater_Controller_Settings.exe to read and change the settings of a controller connected via USB.

The touchscreen provides access to the main settings.
The PC settings editor lets you edit the detailed settings below and save them to the controller EEPROM.
After connecting via USB, select the COM Port and click [Load] to read the current settings. After editing, click [Save] (the middle button).
Close other programs using the same COM port, including the Arduino IDE Serial Monitor.

PC Settings Reference

The values in the screenshot are examples, not defaults or recommended values. Check the time units carefully: minutes, seconds, or 100 ms.

Basic Settings

Screen LabelDescription and Settings
COM portThe COM port used for the USB connection. Select the port assigned to the connected ESP32-S3.
LanguageSelect the display language. Choose English for the labels shown in these screenshots.
Hang timeTransmit hold time after reception ends, in seconds. Corresponds to HANG on the touchscreen.
Transmit time limitContinuous transmission limit, in minutes. Corresponds to TOT on the touchscreen.
Lockout timeAfter TOT stops transmission, the receive input must remain inactive for this number of seconds before lockout is released.
CW speedCW speed in words per minute (WPM). Higher values produce faster Morse code.
CW tone frequencyCW tone frequency in Hz. For example, 700 means 700 Hz.
CW messageThe CW message, such as your station call sign. Use alphanumeric text, up to 19 characters.
SQL active levelActive polarity of the external squelch input. Select LOW or HIGH to match the receiver SQL output.
PTT active levelPTT output polarity during transmission. Select LOW or HIGH to match the connected PTT interface.
Receive detectionSQL input: Detect reception using the external squelch signal.
VOX: Detect incoming audio in software.
SQL debounceReceive input qualification time.
The value is multiplied by 100 ms (0.1 seconds). For example, 1 = 0.1 seconds and 10 = 1 second.
VOX thresholdAudio detection threshold in ADC units. Lower values increase sensitivity.
End beep styleHANG end tone style. OFF: none; 1tone: one tone; 2tone: two tones.
End beep frequencyBase frequency of the HANG end tone, in Hz.
End beep durationHANG end tone duration setting in ms. For example, 80 = 0.08 seconds.
Voice languageVoice announcement language. Select English or Japanese. Matching audio files are required.
LCD displaySelect OFF (no LCD) or ON (LCD fitted) to match the controller hardware.

Schedule

Screen LabelDescription and Settings
CWID modeMODE_A: Transmit in response to access after the interval has elapsed. MODE_B: Transmit periodically according to the clock.
CWID intervalCW ID interval in minutes. 0 means OFF.
CWID allowed from / CWID allowed untilAllowed CW ID transmission hours. Start is included; end is excluded. 0–24 means all day. Overnight ranges are allowed.
Voice ID modeOFF: Disable voice ID. ON: Hourly voice ID and time announcements.
Test (every minute): Test every minute. Select ON or OFF for normal operation.
Voice contentChoose 1. Time + announcement, 2. Time only, or 3. Announcement only.
Announcement intervalInterval in minutes, used only with Announcement only.
Voice allowed from / Voice allowed untilAllowed voice transmission hours, set separately from CW ID. Start is included; end is excluded. 0–24 means all day. Overnight ranges are allowed.
Voice ID start secondThe second within the minute at which audio playback processing starts (0–59).
