General Settings

The General Settings set in a MOTOTRBO codeplug or configuration, contains numerous settings related to radio or repeater operation. Depending on the model and software version, the following sections are shown:

General

Radio Alias

Radio Alias is a CPS/RM setting that can be used to identify a display-model radio to the user via the MMI or a repeater via RDAC. This text string is stored in the codeplug and can be up to 16 Unicode characters long. On non-display models, the string is still stored in the codeplug but will not be displayed anywhere. In Radio Management Radio Alias can be used to identify the radio in addition to the serial number.

When cloning a radio using CPS2, this string can be skipped (i.e. not overwritten).

It is not related to Caller Alias (a.k.a Talker Alias).

The SL1600 does not support Radio Alias.

Radio ID

Radio ID is the unique number assigned to a radio using CPS/RM. The numbering scheme is described in ETSI TS 102 361-1 Annex A. The standard defines a range between 00000116 and FFFCDF16 - or 1 to 16776415. The range 16776416 to 16777215 is reserved for future expansion and non-addressable gateways.

The Radio ID is included in all digital transmissions including data (e.g. Location) and control messages (e.g. Radio Check). It is also used by other calling radios when making an individual voice call.

This number must be unique to each radio.

In a Capacity Plus system, the valid range is 1 to 65535.

In an IP Site Connect system, this ID is used to uniquely identify the IP Site peers and the IP Site masters and must be unique. The same is true for Capacity Plus systems.

The Radio ID entered in the repeater is not transmitted over the air but is used when making a telephone call via an Analogue Phone Patch.

TX Caller Alias (Mobiles and Portables)

Setting this to anything other than no will enable this feature. For more details, see Caller Alias below.

This setting is only applicable to mobile and portable radios.

Caller Alias (Mobiles and Portables)

Radios which do not support this feature will merely display the Radio ID or potentially the Radio Alias. Radios which do support this feature will display the Caller Alias.

Inband Caller Alias (a.k.a. Talker Alias) is a feature that allows a MOTOTRBO radio to transmit a user-defined text string of up to 31 characters with all voice calls. The text string can either be 31 UTF-8 or UTF-16BE characters long, depending on the CPS/RM TX Caller Alias setting. This string is transmitted as part of Link Control PDU embedded in the SYNC of each timeslot.

It was standardised in ETSI TS 102 361-2 v2.5.1 and described in Section 5.4.

This feature would be useful for customers who have users that share radios between shifts. At the start of the shift, the user would enter their name (or some identifier) via the menu. This information would then be shown on any radios or dispatch consoles party to that call (Private; Group or All Call) whenever that user transmitted voice. At the end of the shift, this can either be deleted or changed.

This text string does not necessarily need to be programmed via CPS or RM so (particularly in the case of RM) one can continue to use one configuration between many radios as usual. If no text string is used, the receiving radios will simply show the name from the contact list or the Radio ID.

The CPS/RM Edit Caller Alias setting allows a technician to configure a radio to optionally restrict editing of the Inband Caller Alias. The choices are:

• Fixed. The Inband Caller Alias can only be configured in CPS or RM.
• Radio Menu. The Inband Caller Alias can be altered from the radio menu - applicable to display models only.
• Radio Menu and Power Up. The Inband Caller Alias can be altered from the radio menu or upon power on - applicable to display models only. In the latter case, when turning a radio on, the user will be prompted to enter the required string.

Radios without a display and keypad also support Inband Caller Alias but only on transmission and only as a fixed (string editable in CPS/RM only) configuration.

Inband Caller Alias works on all MOTOTRBO topologies and is supported by all radios on M2020.02 software or later.

All radios support a local cache of up to 500 aliases. This cache is erased on power down. If a radio receives a transmission from another radio which is not in the local alias cache, it will display the name from the contact list or the radio ID until the complete TX Caller Alias is received.

GNSS (Mobiles and Portables)

See GNSS

Site Search Timer (Mobiles and Portables)

Site Search Timer is a CPS/RM setting that allows the amount of time (between 0 and 255 seconds) a radio will wait for the user to either activate Site Lock or to repeat an Active Site Search. If the timer expires with no user input, the radio reverts back to automatic roaming (also known as Passive Roaming) provided Site Lock feature is disabled. This is a radio-wide feature which means the setting is applicable in all operating modes and on all channels. This timer begins immediately after an Active Site Search has found another site in the site or roam list.

This is a digital mode feature and would be used when the radio is on a IP Site Connect or Capacity Plus system. Site Search Timer is not used/needed in Capacity Max.

ARS Initialization Delay (Mobiles and Portables)

ARS Initialization Delay is a CPS/RM setting that allows the duration of the random delay before an Automatic Registration Service (ARS) message is sent.

On conventional systems with many radios, channel collisions can occur when many radios are powered on at the same time or a RF site temporarily goes down. When this happens, it may take a long time for all the radios to announce their presence to the application successfully.

System designers can avoid this by setting it to anything other than zero (default). For example, setting the ARS Initialization Delay to zero will make the radio choose a random time between 5 and 15 seconds to send the ARS. Whereas setting the timer to 30 minutes will make the radio use a random time between 5 seconds and 30 minutes to send the ARS.

ARS is a digital mode feature but is not supported on the DP1400; DM1600 and DP540. ARS is also not used/needed on Capacity Max, which has its own mechanisms to handle mass registration.

TX Preamble Duration (Mobiles and Portables)

TX Preamble Duration is a CPS/RM setting that will make the radio add a string of bits in front of a data message or control message (Text Messaging, Location Messaging, Registration, Radio Check, Private Call, and other data message or control message) before transmission. This preamble prolongs the message and thereby reduces the chances of a transmission being missed by any receiving radios.

This value can be increased in all the transmitting radios if scanning radios are often missing data messages. However, a larger preamble occupies the channel longer. Therefore, increasing the Transmit Preamble Duration will increase the success rate of data received while radios are scanning, but will decrease the amount of data that can be accommodated on the channel. The range is between 0ms and 8640ms in increments of 60ms. If set to zero, no preamble is sent (i.e. it is disabled).

Since data and digital signalling messages are typically shorter in duration than voice transmissions, it can be difficult for a scanning radio to detect these messages and land on the channel in time. This is especially true as the number of Scan List members increases because the amount of time between a scanning radio’s repeated samples of a particular Scan List member increases, making it less likely to be on the channel at the exact moment that the data or digital signalling message begins.

Another factor is the amount of activity on each Scan List member; basically, the more active each Scan List member is, the more likely that the radio is suspending its scan operations to receive on each of those Scan List members, further increasing the likelihood that the radio will not receive the data or digital signalling on another Scan List member. Therefore, if scan is used, the TX Preamble Duration needs to be increased as follows.

Number of Scan List Members

		A
		0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16
D	0	-	-	480	480	480	720	720	720	960	960	960	960	960	1200	1200	1440	1440

A is the number of analogue channel and D is number of digital channels in the selected scan list.

If a radio is solely being used on a single site conventional system and Battery Saver is disabled, then TX Preamble Duration should not be set to 0. The default value is 960ms.

Voice Pretime Duration (Mobiles and Portables)

Voice Pretime Duration is a CPS/RM setting that will make the radio add a pretime burst transmission to a voice call. This duration allows radios, with Scan enabled, enough time to connect to the channel before audio is transmitted.

When a radio is on a conventional system (e.g. simplex; single site or IP Site Connect) and is scanning a number of channels for voice traffic, it can potentially miss the start of a voice call. The probability of missing the beginning of the transmission and joining the call by means of late entry increases in proportion to the number channels in the scan list. Therefore, to reduce the probability of missing the beginning of the voice transmission, the radio can be configured to send a larger number of voice headers preceding the voice payload.

Increasing the Voice Pretime Duration increases the amount of time between the user pressing PTT and being heard by other call parties, so speaking too early will result in truncated audio. Therefore, it is highly recommended that the Talk Permit Tone is enabled.

The below table lists the recommended values in milliseconds:

Channels in Scan List	Talk Permit Tone Disabled	Talk Permit Tone Enabled
1	-	-
2	120	60
3	240	180
4	300	240
5	420	360
6	540	480
7	660	600
8	720	660
9	840	780
10	960	900
11	1080	1020
12	1260	1200
13	1440	1380
14	1560	1500
15	1740	1680
16	1860	2220

The default value is 0ms.

TX Inhibit Quick Key Override (Mobiles and Portables)

TX Inhibit Quick Key Override is a CPS/RM setting that, when enabled (ticked), will allow the user to override the TX Admit Criteria on an analogue channel by pressing the PTT twice within one second.

Monitor Type

Monitor Type is a CPS/RM setting that will alter the speaker unmute conditions when on an analogue channel. This function is triggered by either a button press or via a GPIO pin configured to do this.

• When set to Open Squelch, the radio will unmute regardless of whether there is any channel activity. If no activity is present, white noise is heard through the speaker.
• When set to Silent, the radio will only unmute if there is channel activity.

If the Monitor feature is activated by pressing the assigned programmable button or triggering the GPIO pin, the PL Type setting in Scan will be overridden, if it is is enabled.

Note: This feature is supported in analogue mode only.

Minimum Speaker Volume (Mobiles and Portables)

Min Speaker Volume Muted and Min Speaker Volume Level are two CPS/RM settings that will determine the speaker audio level when the user has turned the volume control all the way down to zero.

If Min Speaker Volume Muted is enabled (ticked), Min Speaker Volume Level (dB) will be greyed out. This means that when the volume potentiometer is at its lowest level, no audio will be present at the speaker. If disabled, one can specify a value in Decibels. This option prevents the user from turning the volume so low that any incoming calls are missed.

Valid Range for Minimum Speaker Volume Level

Model	Minimum	Maximum	Increment
Portables	-30	12	1
Mobiles	-39	18	1

The maximum and minimum range showed in these tables vary by radio model. The range displayed for some models may be different to those shown above.

This feature overrides any value set in Volume Offset (dB) if set to any value other than Muted.

Unlink Monitor

Unlink Monitor is a CPS/RM setting that will make the Permanent Monitor setting/feature ignore the Admit Criteria setting. If Admit Criteria is set to Channel Free, Unlink Monitor must be enabled for Permanent Monitor to function. If Admit Criteria is set to Always, Unlink Monitor has no effect.

Off-Hook Disables PL

Off-hook is a mobile feature that refers to the way in which the mobile microphone operates. When hung on (attached to) the hang-up clip, contacts on the stud on the back of the microphone are shorted and therefore becomes on hook. Removing the microphone from the clip takes it off hook.

When ticked, the radio will bypass PL or DPL squelch on an analogue channel when the microphone is off hook.

Group Call Hang Time (Repeaters)

Group Call Hang Time sets the duration the repeater reserves the channel after the end of a radio talkgroup transmission. During this time, only members of the active talkgroup can transmit. The result is smoother communications and fewer call setups.

The value cannot be zero in Capacity Plus systems and must be equal to or less than the Subscriber Inactivity Timer (SIT) (ms) value.

This setting is applicable to digital mode only and becomes disabled if the repeater is used for analogue operation only.

Maximum	Minimum	Increment
7000 ms	0 ms	500 ms

Private Call Hang Time (Repeaters)

Group Call Hang Time sets the duration the repeater reserves the channel after the end of a private call transmission. During this time, only the call parties can transmit. The result is smoother communications and fewer call setups.

The value cannot be zero in Capacity Plus systems and must be equal to or less than the Subscriber Inactivity Timer (SIT) (ms) value.

This setting is applicable to digital mode only and becomes disabled if the repeater is used for analogue operation only.

Maximum	Minimum	Increment
7000 ms	0 ms	500 ms

Emergency Call Hang Time (Repeaters)

Emergency Call Hang Time sets the duration the repeater reserves the channel after the end of an emergency call transmission. During this time, only members of the Group that the channel is reserved for can transmit. When configuring a system, one may want to set a longer hang time to reserve the channel long enough to receive an emergency response.

Maximum	Minimum	Increment
7000 ms	0 ms	500 ms

Talkaround Group Call Hang Time (Radios)

Talkaround Group Call Hang Time is a CPS/RM setting that determine the behaviour of the radio when talkaround mode has been activated on a digital channel. During this call hang time, the radio will respond to the ongoing call. If the ongoing call is a private call, the radio will respond to the calling radio. Once this time has expired and the user presses PTT, the radio will set up a with the configured TX Contact Name.

Maximum	Minimum	Increment
7000 ms	0 ms	500 ms

Talkaround Private Call Hang Time (Radios)

Talkaround Private Call Hang Time is a CPS/RM setting that determine the behaviour of the radio when talkaround mode has been activated on a digital channel. During this call hang time, the radio will respond to the ongoing call. If the ongoing call is a private call, the radio will respond to the calling radio. Once this time has expired and the user presses PTT, the radio will set up a with the configured TX Contact Name.

Maximum	Minimum	Increment
7000 ms	0 ms	500 ms

Call Hang Time

Call Hang Time (sometimes known as the COR timeout; COR delay; or repeater tail) is a CPS/RM sets the duration the repeater will keep the repeater transmitting as soon as any radio transmission ends. If set to zero, the repeater will stop transmitting as soon as any radio user releases the PTT. Setting it to a value above zero allows radios users to check whether they are in range by simply pressing the PTT and listening for the carrier (tail).

Note that this is an analogue-only feature only available in repeaters.

Repeat Gain

The Repeat Gain is used to adjust the repeater's talk through deviation. When set to zero, an uplink signal with around 1kHz deviation will produce around 1kHz deviation on the downlink. Setting this to 3dB will in turn cause the repeater to produce 2kHz deviation However anything high than that will result in limiting, depending on the chosen Channel Spacing.

Maximum (dB)	Minimum	Increment
6.0	-6.0	0.5

Antenna Relay Delay Timer

When the repeater operates as a tome remote controlled analogue base station, an antenna relay can be used. In such cases, the Antenna Relay Delay Timer setting is used to adjust the duration it takes for the relay to switch between the TX and RX ports. When set to anything other than zero, the repeater will assert the Antenna Relay GPIO pin - assigned to then will wait this amount of time before beginning to transmit. The repeater switches the antenna back to the RX port and sets the GPIO pin to its inactive state after it stops transmitting. The duration set depends on the type of accessory switch, or relay, being used to switch the antenna between ports.

Valid Range

Maximum	Minimum	Increment
375 ms	0 ms	25 ms

The Antenna Relay pin selection is assigned to a GPIO and is triggered by the repeater. The repeater transmits if this pin is active and after the Antenna Relay Delay Timer expires.

For MTR3000, the Antenna Relay pin selection (X371BA), which uses the P10 backplane connector (not the J7), still requires a J7 GPIO to be mapped to the antenna relay function in order for the X371BA option to become operational.

This feature is applicable to MOTOTRBO repeaters operating analogue mode only. It can also only be used with an external controller (e.g. tone remote adapter). An antenna replay would only really be used when there is one base station and one antenna at that location. If there are more base stations, a multicoupler-combiner may be a better choice.

This has nothing to do with the high speed RF relay used on the SLR1000 (and other repeaters) to support Extended Range Direct Mode. An electromechanical RF relay cannot be used for Extended Range Direct Mode!

TX Power

The transmit power of a MOTOTRBO repeater or mobile can be set anywhere between the following values:

	DR3000 25W		DR3000 45W		MTR3000		SLR1000		SLR5500		SLR8000		SL series Portable		25W Mobiles		45W mobiles		Remarks

If MOTOTRBO Tuner has been used to re-tune the TX High Power (W) to 2,5W, then the 3,0W setting corresponds to 2,5W instead of 3,0W.

Disable All LEDs

Disable All LEDs is a CPS/RM setting that, as the same suggests; when enabled (ticked), will disable all LEDs including the backlight and power up LED, regardless of the backlight setting.

Backup Repeater Connected

When disabled, the Repeater is operating in the standalone mode. This feature should be enabled when the Repeater is intentionally operating as the primary Repeater in a redundant Repeater setup. In this setup, the secondary Repeater is operating in the standalone mode.

If Backup Repeater Connected is unticked, the GPIO configured for Major Alarm will only change state (either high or low, depending on what Active Level is set to) when specific faults occur. If it is ticked, the GPIO configured for Major Alarm will change state when any alarm level occurs. Enabling (ticking) Backup Repeater Connected is optional – it depends on whether one wants a minor alarm to cause a switchover.

To ensure the switchover occurs upon loss of power to the primary repeater, it is recommended to set the Active Level of the Major Alarm GPIO to low. This way, as long as the primary repeater is powered and there is no alarm, the GPIO will be high. Removing power from the primary repeater makes the output go low. The Active Level on the Repeater Disable GPIO of the alternate (standby) repeater must therefore also be set to low. This also means that the cable must be connected at all times – otherwise a switchover will occur when there is no fault!

Sign In / Sign Out

Sign In / Sign Out is a CPS/RM setting that, when enabled, will activate the API and feature which allows a radio user to sign in or sign out of a third-party server from the radio with their identity. Additionally, the radio will give an indication whether they have has signed into the third-party server or not on the home screen of a display-model radio. The sign-in information is kept until the radio powers down or the user signs out manually. The Sign In / Sign Out message follows the standard protocol of ARS User Register / Deregister.

Secure Sign In ID

This check box allows the technician configuring the radio to specify whether or not the Sign In ID will be handled securely, like a password. When this check box is checked, the Sign In ID will not be shown on the Home Screen and will be partially hidden when the entering the Sign In ID much like a password is.

Test Mode

This tick box enables or disables access to the radio test mode. See Test Mode.

Scrambling Frequency

Certain MOTOTRBO models support Frequency Inversion Scrambling on analogue channels. This scrambling method provides some degree of communications protection from casual eavesdroppers. When turned on, the transmitting radio will modulate a baseband frequency such that the spectral components of the transmitted voice are inverted (low tones become high, and higher tones become low). The receiving radios perform the opposite such that the presented audio is intelligible. Anyone listening to the communications, who does not have scrambling enabled, cannot hear what is being said. MOTOTRBO CPS/RM allows the technician configuring a radio, to choose one of three possible baseband frequencies (listed below). The chosen frequency must be the same on all participating radios.

The following choices are available:

• 3,29 kHz
• 3,39 kHz
• 3,50 kHz

The level of protection offered by Frequency Inversion Scrambling is very poor and it is possible to monitor scrambled transmissions with fairly simple equipment.

Battery Type

The XiR C1200, XiR C2620, and XiR C2660 are unable to detect what battery has been attached. This field allows the technician to define what battery is used with this radio by default. The user can also change this from the menu.

Home Channel

Home Channel is a radio feature that will remind the user that they have been away from their home channel for too long. The time it takes until the reminder is sounded, is based on the Home Channel Reminder Interval. The alert can either be in the form of an alert tone or voice announcement. This feature is not available in the first generation MOTOTRBO radios

• Home Channel Zone sets the Zone where the Home Channel is located. If Home Channel is not needed, simply set this to None.
• Home Channel sets the Channel in the above Zone.
• Home Channel Reminder Interval sets the interval until the first Home Channel Reminder and the subsequent interval between reminders. This is only applicable if Home Channel and Home Channel Zone are not set to None.

Antenna Selection

The VHF model SL1600 and SL2600 require some adjustment to suit the antenna used. This field allows the technician to choose the settings that best match the antenna characteristics. The following choices are available:

• Stubby
• Whip 1 (136MHz-144MHz)
• Whip 2 (144MHz-156MHz)
• Whip 3 (156MHz-174MHz)

Illegal Carrier Timer

See Illegal Carrier.

Illegal carrier RSSI Threshold

See Illegal Carrier.

Illegal carrier

Illegal Carrier is a CPS/RM setting in the SLR repeaters that, when enabled, will make the repeater generate a RDAC alarm if an interfering signal is detected. The interfering signal must be present for longer than the Illegal Carrier Timer with a signal strength of more than the Illegal Carrier Threshold. The severity of the alarm can be configured to be either Major; Minor or Informational.

The repeater regards a DMR transmission with an incorrect Colour Code or any other non-DMR signal as an illegal carrier.

The repeater behaviour depends what Illegal Carrier Alarm is set to. If set to Informational, the repeater may continue to operate normally, depending on the nature and duration of the interference. if set to Major, the repeater will be become disabled until it gets reset.

If the repeater is part of a Capacity Plus or Capacity Max system and Illegal Carrier Alarm is set to anything other than Informational, it will remove itself from contention for being a Rest Channel or Control Channel host whenever there is interference. If an illegal carrier is detected by a control channel host, this function will be transferred to the next available control channel capable repeater.

Radio Keep Alive

Radio Keep Alive allows the user to enable/disable the keep alive signal without interfering with voice communication. This has nothing to do with the repeater setting.

Codeplug Password

This allows the codeplug to be protected by means of a password. See Codeplug Password Protection.

Check for Password

This drop-down list allows the user to select the password policy for the codeplug password. Choices are None, Read Only, and Read/Write. This drop-down list is applicable for mobile and portable radios only.

This drop-down list is greyed out and set to None when the codeplug password is blank. The default value for this drop-down list is Read Only when the codeplug password is not blank. If the user selects Read/Write, password will be required during read, write, clone, recover, and convert operations.

The write choice is also region dependant.

Maximum Check for Password Attempts

This configuration allows the user to specify how many attempts to enter the codeplug password is allowed by the radio before the radio is locked.

Radio Certification Type

This field allows you to choose the radio certification type.

Respond Caller

Respond to caller is a feature that defines how the PTT button works when receiving a private call. If enabled, the radio follows the expected MOTOTRBO behaviour of responding to the private call: pressing the PTT answers the call and alerts the caller. If disabled, pressing the PTT button causes the radio goes back to the home screen and sets up a call with the configured contact name (this is set in the selected personality/channel).

Radio Language Display

This field sets the display language for models with a display. Also see Language Pack.

Digital or Analog BSI

This field allows the technician to configure the BSI transmission in either Digital or Analog format.

Mute Timer

This feature enables privacy when the user enters into a quiet environment (for example, an important meeting) and the user does not expect the radio to play out any audibles such as over the air (OTA) voice, tone, voice announcements, or Text to Speech announcements. The mute mode feature provides the functionality to address such scenarios.

Battery (Repeaters)

The SLR5500 and SLR8000 are able to trickle-charge a single lead-acid battery. The Battery section of the General Settings allows the following parameters to be configured:

• The Battery check box allows the user to indicate whether or not the battery is supposed to be connected.
• The DC System Nominal field allows the user to choose the nominal voltage for the radio. The choices are 12V and 24 V.
• The DC Operation Only field enables or disables the AC Power Alarm.
• The DC Primary Source check box allows the user to set the DC port as the primary power source.
• The Battery Charging check box allows the user to enable or disable battery charging.
• Output Charger Voltage 12V (V) allows the charge voltage to be set on a SLR55500 and SLR8000.
• Output Charger Voltage 24V (V) allows the charge voltage to be set on a SLR8000.

Alarm Type (Repeaters)

The Alarm Type section of the General set contains the following fields:

The Reference Clock Source Type drop-down list allows the user to select reference clock source type.

The External Clock Frequency drop-down list allows the user to select external clock frequency. The choices are 5MHz or 10MHz.

For the following fields, the choices are Major; Minor or Informational. If Major is selected, the repeater will generate a major alarm in RDAC or System Advisor and will take itself out of service. If Minor is selected, the repeater will generate a minor alarm in RDAC or System Advisor but will not take itself out of service. In the case of a minor alarm, the repeater will continue to function normally but with some impairment depending on the nature of the fault.

If Informational is selected, no alarm is generated and either RDAC or System Advisor will receive information about the event.

• RF Power Control Alarm
• Power Unleveled Alarm
• Modem PA Alarm
• Temperature Alarm
• Power Roll-back Alarm (2dB)
• Power Roll-back Alarm (3dB)
• VSWR Minor Alarm
• VSWR Major Alarm
• PA Temp Alarm
• PA Fan Alarm
• Power Supply Fan Alarm
• Power Supply Over Temperature Alarm
• AC Power Alarm
• Bad Battery Alarm
• Low Battery Alarm
• Battery Disconnected Alarm
• Modem Fan Alarm
• Illegal Carrier Alarm

Temperature alarms as well as the major VSWR alarm are signs of imminent catastrophic failure. Should either of these arise, a site visit must be undertaken to correct the fault without delay.

CWID (Repeaters)

In some countries it is necessary for licensees to periodically transmit their callsign using some human interpretable method. A popular means for achieving this is using morse code. When enabled, CWID will cause the repeater to periodically transmit using analogue FM and transmit the below ID in morse code.

• The ID field contains the identification characters assigned by the local regulatory authority and are periodically transmitted in Morse Code over the air.
• The Tone Frequency (Hz) specifies the frequency used to produce the morse code tones. 800Hz is considered the norm.
• TX Interval (min) sets how often the repeater will key up and send the above ID. If there is a call in progress, the transmission will be delayed. The value should ideally be less than the Mix Mode Timer to give the repeater an opportunity to send the ID at the end of a conversation prior to having to send the ID mixed with analogue repeat audio. Setting this to zero disables CWID.
• When Mix Mode Timer (min) is set to anything other than zero, the repeater will generate the ID mixed with analogue audio when the repeater is repeating analogue signals or is in analogue hang time and the programmed mix mode timer has expired.
• Rate (WPM) sets the speed for the morse code ID in words per minute. 10 to 12 words per minute is considered the norm. Aeronautics uses 5WPM for VLF beacons but this may be too slow.
• If Strip PL is ticked, PL or DPL is not sent when the ID is transmitted. In other words, CWID is sent using carrier squelch (CSQ).

Configuration Bits

The configuration bits allows for future configuration requirements of the radio and to enhance the future operational capabilities of the radio if and when required.
