Resources

Recommended Raspberry Pi Hardware

The following packages are the recommended Raspberry Pi Kits for the Broadcastify Raspberry Pi Feed Appliance Image. These packages provide everything you need in kit form to be up and running in minutes.

  • Raspberry Pi 5 - Best for 2 or more darkice feeds, or running SDR-Trunk. Will also broadcast a large trunked system site to Broadcastify Calls using Trunk Recorder.
  • Raspberry Pi 4 - Best for 2 or more darkice feeds. Will also broadcast a medium size trunked system site to Broadcastify Calls using Trunk Recorder.

Recommended Soundcards

The Raspberry Pi does not come with a microphone built in, so you will need a USB soundcard for each feed you plan on broadcasting. The following are two recommended and tested soundcards. The Ground Loop isolator listed below is strongly recommended for each feed to reduce hum and audio interference.

Ground Loop Isolator

Don't skip this step. Read it. Seriously. A ground loop isolator strongly recommended for each feed to reduce hum and audio interference.

Download and Flash Image to SD Card

To get started with your Raspberry Pi, download and install balenaEtcher on your computer. balenaEtcher is used to flash the preconfigured Broadcastify Image to an SD card.

Steps to Flash Image to SD Card using balenaEtcher:

  1. Insert or attach a blank SD Card to your computer
  2. Run balenaEtcher
  3. Choose "Flash from URL" and enter the following image URL.
  4. Select your SD card as the target
  5. Click Flash!
  6. When the flash has completed, insert the SD card into your Raspberry Pi, Power On, and follow the configuration sections below:

Update to Latest Version

Fixes and updates to the image are periodically released. To update to the latest version follow these steps:

  1. Start the Raspberry Pi with the SD card you flashed from the "Download and Flash Image" section above.
  2. Double Click the "BCFY Shell" icon on the desktop
  3. Enter Option [9] - Check for Updates
  4. Enter your Broadcastify Username and Password when prompted.
  5. If updates are available you will be prompted to install them
  6. Reboot the device if prompted to do so

Configure Broadcastify Darkice Feed

If you want to broadcast a single feed to Broadcastify, connect your scanner or receiver to the "Mic Input" on your soundcard and follow these steps:

  1. You should already have an approved feed application here: Broadcastify Feed Application. You can review your approved and active feeds here: My Audio Feeds
  2. Start the Raspberry Pi with the SD card you flashed from the "Download and Flash Image" section above.
  3. Double Click the "BCFY Shell" icon on the desktop
  4. Enter Option [2] - Configure Darkice
  5. Enter [1] to configure Darkice Instance #1
  6. Enter the Soundcard Instance # for your attached USB Soundcard Device.
  7. Enter your Broadcastify Username and Password when prompted. This will retrieve a list of all your approved Broadcastify Feeds
  8. Enter the feedId of the feed you wish to configure
  9. Choose Y/N to configure the feed to start on boot
  10. Choose Y/N to start the feed broadcast
  11. After a few moments, you can check the status of your feed at: My Audio Feeds

Configure Trunk Recorder for Broadcastify Calls

If you want to capture a trunked radio system site(s) and send to Broadcastify Calls, follow these steps. You will need to have a trunk-recorder supported SDR attached to the Raspberry Pi.

You will need to provide your own Trunk Recorder config.json file. More information on Trunk Recorder and it's configuration can be found here: Trunk Recorder. A supported SDR is required (see below)

  1. You should already have an approved Broadcastify Calls Ingest Node application from here: Broadcastify Calls Ingest Feed Application. You can review your approved and active ingest nodes here: My Call Ingest Nodes
  2. Open a terminal instance by clicking the terminal icon on the top toolbar
  3. Copy or create your trunk recorder config.json file in the following path: /home/pi/bcfy/configs/trunk-recorder/config.json
    Note: trunk-recorder example template files are located in /home/pi/bcfy/configs/templates/trunk-recorder . You can copy one of these example files to /home/pi/bcfy/configs/trunk-recorder/config.json to get started.
  4. Double Click the "BCFY Shell" icon on the desktop
  5. Enter Option [1] to Start/Stop Services
  6. Enter Item [2] to configure trunk recorder
  7. Enter Option [1] to start trunk recorder
  8. Enter Option [4] to enable trunk recorder to start on boot
Note: The trunk-recorder log can be found at /home/pi/bcfy/logs/trunk-recorder.log and is automatically rotated daily.

Recommend SDR Hardware for Trunk Recorder

The following SDRs are recommended for use with Trunk Recorder.

AirSpy Products Listed Below are also STRONGLY recommended for their stability and wide bandwidth:

The Broadcastify Shell (BCFY Shell)

The Broadcastify Shell allows you to configure and manage most of the services and features of the Broadcastify Feed Appliance Image. You can run the shell by double-clicking the "BCFY Shell" Icon on the desktop.
