3/5: Creating the configuration file

Step 3/5: Creating the configuration file based on the device list

Web Radio Control setup step for listing connected devices

  1. Download this configuration file template and save it on the local disk: wrc-config-template.yaml

  2. Open the downloaded configuration file template using a text editor application

  3. Click the List devices button in the Web Radio Control setup user interface to list attached USB serial port adapters and USB sound cards

Configuration file template

The text below is a copy of the configuration file template (downloadable from the link above) for documentation purposes:

global:
  uniqueSystemDeviceNames: false

server:
  publicHostname: "DOMAIN_NAME"
  ipv6: false
  lanMode: false

devices:
- id: "radio1-id"
  type: "rigctld"
  rigctld:
    localInstance:
      enabled: true
      model: RADIO_MODEL_NUMBER
      rigDevice: "SERIAL_PORT_DEVICE"
      serialSpeed: SERIAL_SPEED
  media:
    stream:
      audioInputDeviceName: "AUDIO_INPUT_DEVICE_NAME"
      audioOutputDeviceName: "AUDIO_OUTPUT_DEVICE_NAME"

The configuration file template can be downloaded from: wrc-config-template.yaml

Filling in the configuration file template

Replace the placeholders (e.g. DOMAIN_NAME) in the configuration file template. The placeholders that need to be replaced are listed below. Please pay attention to preserve any double quotes and spaces around the placeholders.

The configuration file format is called YAML, which is sensitive to the number of spaces in the beginning of each line. Please make sure to not change the number of spaces!

Some of the following placeholders in the configuration file template depend on the radios and other accessories in use, so you will have to look up them in the List devices listing of the setup user interface.

Configuration options

The placeholders to be replaced in the configuration file template are:

Application-level and networking configuration

  • uniqueSystemDeviceNames - This setting should be false in most simple station setups, when there is only a single device of each device type (e.g. radio or rotator) to be controlled remotely. The setting allows you to use multiple radios or other peripherals of the same model. Connecting multiple USB devices of the same or similar model may lead to conflicting serial port or audio device names and the uniqueSystemDeviceNames setting with value true resolves these conflicts by exposing the individual USB ports in the device names. When this setting is enabled, it is necessary to keep each device in the same, dedicated USB port at all times.

  • DOMAIN_NAME - Domain name for the Web Radio Control server, which must be the same domain name used for the TLS certificate.

  • ipv6 - Web Radio Control uses IPv4 addresses by default (ipv6 is false). If you wish to use Web Radio Control in an IPv6 network, use value true for the ipv6 setting. Note that when using IPv6 addresses, also the domain name (the DOMAIN_NAME reference above) needs to point to an IPv6 address.

  • lanMode - Web Radio Control assumes that it is accessed through public Internet by default (lanMode is false). If you wish to use Web Radio Control in a closed, private LAN network, use value true for the lanMode settings. Enabling LAN mode prevents use of Web Radio Control via the public Internet.

Radio model configuration

  • radio1-id - An identifier for the radio to be controlled. The identifier is used internally by Web Radio Control to distinguish between radios and other devices. You can choose the identifier freely, but it makes sense to use the radio model as the ID. Note that the ID may only contain characters A-Z, a-z and 0-9. Example: ic7300

  • RADIO_MODEL_NUMBER - Radio model number for controlling the radio. Please find the model number of your radio model from the list of supported radio models in the setup user interface (see the screenshot below) or from the documentation on page supported radios. The manufacturers and models are listed alphabetically. Example: 3073 (for IC-7300)

Radio control configuration

  • SERIAL_PORT_DEVICE - Radio serial port in URI reference format documented below.

    The setup user interface lists all detected serial ports and adapters under title Serial ports (for device control), see the screenshot below. Find the serial port that is connected to the radio from the list of serial ports and copy the text from the URI reference column here. Each URI reference has either an id: prefix.

    The list of serial ports identifies USB serial port adapters with tty, usb in the Subsystem, bus field. Radio models with a USB connector will usually have the radio model and some form of serial number in the id: URI reference, although there is no general rule on what the URI references will look like. With multiple radios of the same model or when using USB — RS-232 adapters it is usually not possible to know which serial port is connected to which radio, so you will have to test each URI reference.

    Example: id:IC-7300_01234567

  • SERIAL_SPEED - Radio serial port communication speed (baud rate). Choose a speed supported by your radio model. Example: 19200

Radio audio device configuration

  • AUDIO_INPUT_DEVICE_NAME - Audio input device name (= RX audio, radio speaker output) for Web Radio Control server. Choose the audio input device name connected to the radio model specified above from the setup user interface listing titled Audio inputs (from radio), see the screenshot below.

    The audio input device name may sometimes contain names of the manufacturer or the radio model to help you identify the correct one. All audio input device names have a prefix of alsa_input.usb for USB sound cards.

    Example: alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo

  • AUDIO_OUTPUT_DEVICE_NAME - Audio output device name (= TX audio, radio microphone input) for Web Radio Control server. Choose the audio output device name connected to the radio model specified above from the setup user interface listing titled Audio outputs (to radio), see the screenshot below.

    The audio output device name may sometimes contain names of the manufacturer or the radio model to help you identify the correct one. All audio output device names have a prefix of alsa_output.usb for USB sound cards.

    Example: alsa_output.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo

Save the configuration file

Save the changes you have made to configuration file template in the text editor.

An example of a finished configuration file

The example below contains configuration for an IC-7300 radio.

This configuration file is only an example and cannot be used as it is, because the radio and audio device names depend on the radio equipment and accessories you use. This example serves primarily as a reference for checking what a finished configuration file for controlling a single radio looks like.

server:
  publicHostname: "my.domain.net"
  ipv6: false
  lanMode: false

devices:
- id: "ic7300"
  type: "rigctld"
  rigctld:
    localInstance:
      enabled: true
      model: 3073
      rigDevice: "id:IC-7300_01234567"
      serialSpeed: 115200
  media:
    stream:
      audioInputDeviceName: "alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo"
      audioOutputDeviceName: "alsa_output.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo"

Configuring additional radio settings and remote control of accessories

The pages listed below document additional configuration settings, which you may need depending on the radio model and if you wish to control other accessories, such as rotators and antenna switches.

Additional configuration settings are necessary, if:

  1. Radio PTT is controlled via RTS/DTR control lines of an RS-232 serial port

  2. You wish to use morse keying (CW) features or an adapter for a physical morse key

  3. You use a Dynamic DNS service for the domain name you have chosen and wish to have Web Radio Control update the IP address of the domain name

  4. You wish to control an antenna rotator

  5. You wish to control an antenna switch

  6. The radio indicates that morse key is constantly held down and the radio does not respond to control commands (usually sent via a separate radio control interface)
