3.3.4 Profile Field Descriptions
3.3.4.1 Common Profile Fields
Field
Description
Profile Name
Create a unique profile name that will appear in the status window of the GoBox control interface. This
name is what your operational profile will be called.
The Profile Name is limited to 8 characters and may only include letters, numbers or a hyphen '-'. The
names “Standby” and “None” cannot be used.
Duplexer Group Tag
If duplexer group tags have been created, you can select a duplexer group to associate this profile with.
Selecting a specific duplexer tag means this profile will only be available on the GoBox control interface if
the corresponding duplexer is installed.
If duplexer group tags have not been created, you can select All and then edit the profile once duplexer
group tags have been created. Selecting All means this profile option will always be available to select on
the GoBox control interface regardless of what duplexer is installed.
Once an operational profile is associated with a duplexer group tag, it may also be chosen as the start-up
profile for a newly installed duplexer.
Rx Frequency
This should be set to the desired centre receive frequency. The installed duplexer must be calibrated to this
frequency to ensure optimal RF performance.
Tx Frequency
This should be set to the desired centre transmit frequency. The installed duplexer must be calibrated to
this frequency to ensure optimal RF performance.
Tx Power
The transmit power in Watts to use for this operational profile.
3.3.4.2 P25 Profile Fields
Field
Description
Rx P25 Type
The Rx P25 Type field indicates the level of filtering the GoBox will apply to a received signal before
repeating the signal.
Monitor
All detected P25 signals will be repeated with the same NAC as was received.
Normal
Only P25 signals with the specified Rx NAC code will be repeated/forwarded.
Selective
Only P25 signals with the specified Rx NAC code and Talkgroup Id will be
repeated/forwarded.
Rx NAC
Tx NAC
The NAC is a feature similar to CTCSS or DCS for analog radios. Repeaters can be programmed to only
repeat P25 signalling when receiving the correct NAC.
NACs are programmed as a three-hexadecimal-digit code that is transmitted along with the digital signal
being transmitted.
Three of the possible NACs have special functions
0x293 ($293)
the default NAC
0xf7e ($F7E)
a repeater set for this NAC will repeat P25 signalling on any decoded signal
received
0xf7f ($F7F)
a repeater set for this NAC will allow all incoming decoded signals and the
repeater transmitter will retransmit the received NAC
Talkgroup
The GoBox may be configured to only repeat P25 signals matching a certain Talkgroup Id.
Allowed values are 1 to 65535 inclusive.
Tx Hang Time
The GoBox may be configured with an additional duration that is included at the end of every voice
transmission. In P25 this transmission consists of additional terminator data units that enable subscribers
to check that their uplink reached the repeater and was rebroadcast successfully.
Allowed values are 0 (no hang time) to 30000 milliseconds.
3.3.4.3 Analog Profile Fields
Field
Description
Rx Subaudible
Tx Subaudible
The Rx subaudible field sets the subaudible tone signalling which a received signal must contain in order to
be repeated.
The Tx subaudible field sets the tone signalling for the transmitted signal.
None
All detected analog signals, subject to the Rx RSSI, will be repeated.
Transmitted signals carry no tone signalling.
CTCSS
Use CTCSS tone signalling. Select the tone frequency from the option field.
