Radio Noise Collective: Open Radio Toolkit<\/h2>\n\n\n\n

This page extends the Radio Noise Collective 2nd Transmission zine artist\u2019 intervention for Neural Magazine #80 2026<\/em><\/strong>. Accessed through the QR code printed in the zine, it gathers practical resources for experimenting with radio as an artistic medium, instrument and collective form of transmission.<\/p>\n\n\n\n

The materials include the Arduino AM transmitter schematic and code, instructions for building and transmitting with improvised antennas, Icestream<\/a> software for autonomous online broadcasting, and an FM\/AM circuit-bending hack for transforming portable radios into playable electronic instruments.<\/p>\n\n\n

\n AM transmitter circuit for Arduino Uno R3 and Arduino Nano Classic.
\n The audio signal is connected to A0 and the two antenna outputs are generated on D3 and D11.\n <\/p>\n

\n This device for AM radio transmission using an improvised antenna was developed for Radio Noise Collective performances by Jenny Pickett and Julien Ottavi.\n <\/p>\n

\n The schematic is adapted from Doctor Volt\u2019s AM Transmitter With Arduino<\/em>, published on Instructables:\n <\/p>\n

This Arduino sketch generates the AM carrier signal and modulates it using an audio input connected to A0. It is designed for the Arduino Uno R3 and Arduino Nano Classic using the ATmega328P\/ATmega328 at16 mHz.\n<\/p>\n

\n The transmission frequency is selected near the top of the sketch by changing the FRQ<\/code> value. The carrier is generated on digital pins D3 and D11, which connect to the transmitter antenna.\n<\/p>\n

AM Transmitter Instructions<\/h3>\n
\n    The transmitter uses two Arduino outputs, D3 and D11, to generate the radio-frequency carrier.
\nThe antenna is connected between these two outputs.\n  <\/p>\n
