Rpt.conf

Rpt.conf is where the majority of the node configuration occurs. Important node settings such as the node CW and voice ID, touchtone commands and timers are set. The default DIAL rpt.conf is well commented (see rpt.conf on GitHub).

Node Number Stanza

The node number stanza is the first stanza in rpt.conf.

[1999]    ; Replace with your assigned node number

rxchannel

The rxchannel key/value pair selects the radio interface. There must be only one rxchannel per node. The selections are:

Value	Description
dahdi/pseudo	No radio, used for hubs
SimpleUSB/usb_1999	SimpleUSB (limited DSP)
Radio/usb_1999	USBRadio (full DSP)
voter/1990	RTCM
Pi/1	Raspberry Pi PiTA
Dahdi/1	PCI Quad card
Beagle/1	BeagleBoard
USRP/127.0.0.1:34001:32001	GNU Radio interface USRP

Sample:

rxchannel = dahdi/pseudo     ; No radio (hub)

Note: This is selecting what is known as (in Asterisk terminology) the channel driver.

duplex

The duplex key/value pairs sets the duplex mode for desired radio operation. Duplex mode 2 is the default if none specified.

Duplex Mode	Description
0	Half duplex with no telemetry tones or hang time. Special Case: Full duplex if linktolink is set to yes. This mode is preferred when interfacing with an external multiport repeater controller. Comment out idrecording and idtalkover to suppress IDs.
1	Half duplex with telemetry tones and hang time. Does not repeat audio. This mode is preferred when interfacing a simplex node.
2	Full Duplex with telemetry tones and hang time. This mode is preferred when interfacing a repeater.
3	Full Duplex with telemetry tones and hang time, but no repeated audio.
4	Full Duplex with telemetry tones and hang time. Repeated audio only when the autopatch is down.

Sample:

duplex = 0     ; 0 = Half duplex with no telemetry tones or hang time.

controlstates

This setting defines the name of the variable named control state stanza. Control states are an optional feature which allows groups of control operator commands to be executed all at once. To use control states, define an entry in your node stanzas to point to a dedicated control state stanza like this:

controlstates = controlstates   ; points to control state stanza

[controlstates]
0 = rptena,lnkena,apena,totena,ufena,noicd  ; Normal operation                                  
1 = rptena,lnkena,apdis,totdis,ufena,noice  ; Net and news operation                                             
2 = rptena,lnkdis,apdis,totena,ufdis,noice  ; Repeater only operation

The control state stanza (below) describes these mnemonics.

Functions Stanza

Status Commands

Status commands provide general information about the node.

Status	Status Function
1	Force ID (global)
2	Give Time of Day (global)
3	Give software Version (global)
4	Give GPS location info
5	Speak the last (dtmf) user
11	Force ID (local only)
12	Give Time of Day (local only)

COP Commands

COP (control operator) commands are privileged commands. Node admins may provide some of these to their user community based on personal preference. COP commands within rpt.conf take the general format of key/value pairs. This COP 7 example would set touchtone *99 to enable the timeout timer.

99 = cop,7

Some COP commands can take multiple parameters. For example this COP 48 would send #3#607 on command.

900=cop,48,#,3,#,6,0,7

DestID and subcode are only specified for the 'C' type message. UnitID is the local systems UnitID. DestID is the MDC1200 ID of the radio being called, and the subcodes are as follows: Subcode '8205' is Voice Selective Call for Spectra ('Call') Subcode '8015' is Voice Selective Call for Maxtrac ('SC') or Astro-Saber('Call') Subcode '810D' is Call Alert (like Maxtrac 'CA')

Control States Stanza

There are several predefined nmemonics (keywords) used in the control state stanza to enable and disable the various features of the controller. These nmemonics correspond to the control operator command to be executed and most of these are the same groups of letters sent back when a single control operator command is executed on the controller.
