Short introduction video of a "Pitchcom" device I built. Credit for the idea goes to Erik Gulbrandsen. This solution is using an Elgato Streamdeck connected to Companion software to send pre-recorded mp3 commands using Playoutbee software wirelessly to a catcher. I used a portaphone Epak radio system but other radio systems could be used.
