This is not a radio. It is a sample player that behaves like a radio.

A digital way to simulate radio-powered compositions by John Cage, Karlheinz Stockhausen and Don Buchla's voltage-controlled radio experiments. It uses a teensy3.1 to play files from a SD card to simulate a voltage controlled AM/FM/Shortwave/Time Travel radio.

Progress

November 2015 
- Rev 3.1 Hardware Revision 
    - 1k Resistors to reduce strain on IC4 when +5v or -0v 
    - Larger resistor pads for easier soldering
    - Neater 7mm resistor outlines on Front board 
- Rev 3 Hardware Revision
    - Completely rerouted for improved grounding, slightly reduced noise 
    - 11m hex spacer connects back and front PCBs together, stronger physical module
    - Reworked CV input circuits
    - Fixes distortion after module playing for hours
    - Straight header outlines for cleaner routing
