TRANS/MISSION_Non-comercial, non-regulated wireless communications.

2017.01.24/28 Open to the public - Tandem Europe Residence Athens, GR.

2016.10.26/27 RIAT Research Institute for Arts & Technology, Vienna, AT.

2016.10-14/16 Radio Revolten – Das internationale Radiokunst-Festival @ Halle, DE.


On a space where telecommunications and media has a strong impact on society, the seminar its aimed as an introduction to self-managed, non-comercial and non-regulated wireless communications.

The TRANS/MISSION seminar its an experimental approach to wireless communications, covering theoretical, practical and tactical topics related to transmission, radio and radio art history, through a hands on workshop where participant will be able to build its own transmitter and experiment with the medium.

Participants will be introduced to audio sonification techniques, active listening and optimal signal reception of radio signals, covering theoretical and practical topics related to the meanings of transmission, the power of sharing information, radio history, construction of electronic devices and establishing guidelines for experimental transmission techniques.

It is aimed at participants interested in sound, transmission, radio art, radio history, acoustics, perception, field recordings, experimental & communicative processes, and dedicated artists, musicians, sound designers, performers, hackers, DIY enthusiasts and curious minds.

No electronic or sound skills are needed to perform these experiments and every experiment can be realized with the specific electronics provided in the workshop, a fine tip soldering iron and the T/M device.

The T/M Device, represents a portable-non regulated analog FM (MONO) / VHF (B&W) transmitter with an USB-soundcard for artistic, academic or research porpoises that has been specially designed for the Radio Revolten festival. The seminar will establish guidelines for experimental transmission techniques through free libre open software and analog DIY hardware.

Technical specifications:

FM / VHF Analog transmitter with integrated USB stereo audio codec.

USB-class compliant full-speed protocol controller with 2 input - 2 output channels.

This is a class compliant open hardware design, which means that is immediately compatible with every current and future version of Linux, Android, Mac OS X, iOS and with Windows (98SE and up) operating systems. The USB protocol controller works with no software code and includes analog PLLs to playback and record with low clock jitter and with independent playback and record sampling rates.


The seminar kit provides all the necessary parts and components required to build the Transmission USB interface:

  • 1x USB interface controller
  • 2x 16 bit Delta sigma ADC (analog to digital converters) and DAC (digital to analog converters)
  • 2x Audio input / Stereo channels:  8, 11.025, 16, 22.05, 32, 44.1, 48 kHz
  • 2x Audio Output / Stereo channels: 32, 44.1, 48 kHz
  • Low drop out - Low noise voltage regulator
  • Buffer operational amplifiers on both input and output.
  • 3x button interface on board for audio control: Volume up - Volume down - Mute
  • 1x Broadband Antenna

Power Supply: 5 V / 70mA. 

Powered from the USB of the computer or an external power bank.

It is not a microcontroller, and thus does not require any internal firmware to operate and does not require any programmer/programming.

During the workshop attendees will have the chance to build a dedicated T/T device -similar to the render above- and different antennas or sensors that they can keep afterwards, giving participants a vast amount of knowledge, interesting and unique audio recordings and hours of further experimentation.
