TyT™ Codeplug Extensions

This section collects all device specific extensions to the codeplug for TyT™, Retevis™ and some Baofeng™ devices.

These extensions are applicable to TyT™ MD-390, MD-UV380, MD-UV390, MD-2017, Retevis™ RT8, RT3S, RT82, RT84 and Baofeng™ DM-1701 radios.

Channel extension

This extension to the codeplug allows to set device specific channel settings for many TyT™ radios (and therefore also many Retevis™ radios). Not all settings are present in all radios. Unsupported settings are ignored during encoding or set to the default value during decoding.

Example 4.4. Example channel settings specifying the default values for TyT™ Retevis™ devices.

tyt:
  loneWorker: false
  autoScan: false
  talkaround: true
  dataCallConfirmed: false
  privateCallConfirmed: false
  emergencyAlarmConfirmed: false
  displayPTTId: true
  rxRefFrequency: Low
  txRefFrequency: Low
  tightSquelch: false
  compressedUDPHeader: false
  reverseBurst: true
  killTone: Off
  inCallCriterion: Always
  allowInterrupt: false
  dcdm: false
  dcdmLeader: false

Common channel setting fields

loneWorker: If true, the lone worker feature is enabled. See also Lone Worker
autoScan: If true, the auto-scan feature is enabled.
talkaround: If true, talk around is enabled. That is, the radio will receive on the input and transmit on the output frequency of the repeater effectively bypassing the repeater. See also Talkaround.
dataCallConfirmed, privateCallConfirmed, emergencyAlarmConfirmed: Enables the confirmation of data, private and emergency calls. These fields are usually disabled as the radio will first establish the connection before the actual call can be started.
displayPTTId: If true, the received analog PTT will be shown.
rxRefFrequency, rxRefFrequency: Specifies some weird reference frequency setting for RX and TX. By default the value Low is used. Possible values are Low, Medium and High.

Channel settings for TyT™ MD-390 and Retevis™ RT8

tightSquelch: If set to true, the silent squelch is used.
compressedUDPHeader: Some unknown flag. Usually disabled.
reverseBurst: If enabled (default), avoids a noise burst at the end of a transmission, when the squelch is controlled by a sub tone.

Channel settings for TyT™ MD-UV390 and Retevis™ DM-2017

killTone: Specifies the kill tone. Possible values are Off, Tone259_2Hz and Tone55_2Hz. Disabling or setting the kill tone to 259.2Hz or 55.2Hz, respectively.
inCallCriterion: Specifies the in-call criterion. Possible values are Always, AdmitCriterion and TXInterrupt.
allowInterrupt: Enables/disables interrupts if inCallCriterion is set to TXInterrupt.
dcdm: If enabled, the dual-capacity direct mode is used for simplex operation. See also DCDM.
dcdmLeader: If DCDM is enabled, this flag specifies whether this radio is the channel leader. That is, if this radio provides the clock for the time-slots.
dmrSquelch: Allows to set the squelch level for DMR channels. This prevents the LED to light all the time. The radio, however, remains silent irrespective of this setting.

Scan-list settings extension

This extension to the codeplug allows to specify device specifics settings for scan-lists.

Example 4.5. Scan-list settings example showing the default values.

tyt:
  holdTime: 500
  prioritySampleTime: 2000

Scan-list settings fields

holdTime: Specifies the hold time in ms.
prioritySampleTime: Specifies the sample-time in ms for priority channels.

Button settings extension

This extension to the codeplug allows to specify the function for each of the programmable buttons on the radio. Please note that not all TyT™ radios have all buttons described here.

Example 4.6.

tytExtension:
  buttonSettings:
    longPressDuration: 1000 
    sideButton1Short: Disabled
    sideButton1Long: Tone1750Hz
    sideButton2Short: MonitorToggle

Must be one of: Disabled, ToggleAllAlertTones, EmergencyOn, EmergencyOff, PowerSelect, MonitorToggle, OneTouch1-OneTouch6, RepeaterTalkaroundToggle, ScanToggle, SquelchToggle, PrivacyToggle, VoxToggle, ZoneIncrement, BatteryIndicator, LoneWorkerToggle, RecordToggle, RecordPlayback, RecordDeleteAll, Tone1750Hz, SwitchUpDown, RightKey, LeftKey or ZoneDecrement.
longPressDuration: Specifies the long-press duration in milliseconds.

Menu settings extension

This extension to the codeplug allows to specify which menu items are enabled. This feature is frequently used in commercial applications to restrict the user to change certain settings in the radio.

Example 4.7.

tytExtension:
  menuSettings:
    hangtimeIsInfinite: false
    hangTime: 10
    textMessage: true

Radio settings fields

montitorType: Specifies the monitor type. Possible values are Open and Silent. This setting only affects analog channels. If Open is specified, the squelch will open if monitoring is enabled.
allLEDsDisabled: If enabled, all LEDs are disabled.
talkPermitToneDigital: If enabled, a talk-permit tone will sound on digital channels.
talkPermitToneAnalog: If enabled, a talk-permit tone will sound on analog channels.
passwordAndLock: Enables and disables the passwords and keypad locks globally. They can also be enabled/disabled individually below.
channelFreeIndicationTone: If enabled, a tone will sound after a transmission has ended to indicate that the channel is free again.
allTonesDisabled: If enabled, all tones (talk permit, channel free, etc.) are disabled globally.
powerSaveMode: Puts the radio is a sleep mode when in idle state (no traffic on the channels). This allows for some power saving. However, the radio will need some time to wake up. Consequently, all other radios in the network need to transmit a wake-up preamble.
wakeupPreamble: Enables the transmission of a short wake-up preamble allowing receiving radios to wake-up in time for the actual transmission.
bootPicture: If enabled, a picture is shown during boot rather than the boot text (see introLine1 and introLine2 in the general settings section).
channelMode, channelModeA, channelModeB: Controls the mode of the radio, VFO A and VFO B. If channelMode is true, the entire radio operates in channel mode (memory mode). This also overrides the channelModeA and channelModeB settings. If channelMode is set to false, the channelModeA and channelModeB specify the mode for the VFO A and B, respectively.
txPreambleDuration: Specifies the transmit preamble duration in milliseconds. If this preamble is the wake-up preamble, is unknown.
channelHangTime: Specifies the channel hang time in milliseconds.
groupCallHangTime, privateCallHangTime: Specifies the group-call hang time in milliseconds. This is the time a group or private call can be answered directly even if that group call is not the default contact of the channel. See also Hang Time.
lowBatteryWarnInterval: Specifies the period of the low-battery warn tone in seconds.
callAlertToneContinuous: If enabled, a call-alert tone will sound until the operator reacts. This setting overrides the callAlertToneDuration setting.
callAlertToneDuration: Specifies the call alert-tone duration in seconds. If callAlertToneContinuous is enabled, the alert tone will be continuous irrespective of this setting.
loneWorkerResponseTime: Sets the lone-worker response time in minutes. See also Lone Worker.
loneWorkerReminderTime: Sets the lone-worker reminder time in minutes. See also Lone Worker.
digitalScanHangTime, analogScanHangTime: Specifies the time in milliseconds, the radio will continue monitoring a DMR or FM channel after the transmission on that channel ended.
backlightAlwaysOn: If enabled, the backlight will stay on.
backlightDuration: Specifies the backlight duration in seconds.
keypadLockManual: If enabled, the keypad lock is enabled manually. If not, the keypad lock gets enabled automatically after a specified period (see keypadLockTime).
keypadLockTime: Specifies the time, after which the keypad lock is engaged automatically unless keypadLockManual is enabled.
powerOnPasswordEnabled: Enables the power-on password.
powerOnPassword: Specifies the power-on password. An 8-digit number. This password must then be entered when booting the radio.
radioProgPasswordEnabled: Enables the radio-programming password.
radioProgPassword: Sets the radio-programming password. An 8-digit number. This password must then be entered when making any changes to the radio/channel settings through the keypad.
pcProgPassword: Specifies the PC programming password. This password is then needed when programming the radio through the CPS. An empty string disables this password.
privateCallMatch, groupCallMatch: If true, the private and group call IDs must match.
