<nettime-ann> Workshop on Software Defined Radio - Musichackspace

µFM - Hybrid analogue and digital MicroFM radio broadcast workshop for raspberry pi During the last past years, the radio world has witnessed the rise of numerous initiatives related to the hybridization of traditional radio means with digital standards and systems, nourishing and renewing the classic radio-amateur practises and approaches such as pirate satellite brazilian radios. [1.]But even if technical protocols such as Software Defined Radio (SDR), streaming and p2p decentralized practices have opened new perspectives, it is mostly the recent new political approaches of radio, such as Kogawa’s MicroFMor the Telecomix Internet radio initiative [3.] that have unveiled new exciting territories. Nowadays, radio is -in its digital transformation, far from the unidirectional relationship with the listener of the FM band. It is open to very local broadcast and wild transmissions over large spectrum, carrying both sounds and data, and offering to rethink its architecture on the principles of rhizomatic and meshed networks.Following the Π-Node experiments [4.], this workshop proposes to explore the use of RTL-SDR antennas, primary conceived for TNT television reception [dongle based on the RTL2832U chipset [5.] and subverted to the reception of various signals from the radio spectrum from 20MHz to 2000MHz. The antenna will be receiving waves of data messages, encoded through Minimodem [6.]. A Raspberry Pi will be transformed in a radio transmitter, using the GPIO 4 and the PiFM software [7.]Participants will use and connect those tools and techniques, in order to create a chain of radio data relays, and trying ultimately to subvert it by various means (radio interferences, sound transformation, data capture and text substitution, etc…)._http://musichackspace.org/events/%c2%b5fm-hybrid-analogue-and-digital-microfm-radio-broadcast-workshop-for-raspberry-pi/&Monday 18th July 2016, 7pm to 10pm@LimeWharf On the hybridisation of digital communication networks and analog radio protocolsThis talk aims to introduce a few chosen actual digital radio infrastructures, networks and initiatives in the perspective of artistic practices. Starting with the very beginning of the amateur radio movements that have emerged with the radio itself, the talk will also cross roads with the birth of offshore pirate radios, the movement of radio libres and their connection with the minitel in Paris and Bologna, Max Neuhaus, John Cage and the experimental uses of radio in sound arts, optical network of data transmission in Czech Republic, the Frei Funk movement in Germany, micronations and data heavens. The talk will end with a presentation of various actual approaches of radio, from the realms of miniFM to the communication networks of high-frequency trading._http://musichackspace.org/events/on-the-hybridisation-of-digital-communication-networks-and-analog-radio-protocols-artist-talk-with-rybn-org/
