SCHLAPPI ENGINEERING – INTERSTELLAR RADIO
DESTRUCTIVE TRANSMISSION LINE
The Interstellar Radio is a faulty transmission line providing several varieties of destructive effects as well as acting as a non-volts/octave complex oscillator when no input is provided.

Interstellar radio converts an audio signal from the input jack to a high frequency pulse train and then back to an audio signal with voltage control over the clock for the up conversion (CARRIER) as well as the down conversion (DEMODULATOR), like a voltage controlled radio transceiver designed for poor reception.

Manipulating these clocks allows for a variety of aliasing, distortion, and frequency modulation type effects. The output is also sent to a comparator along with the input, and the result is available at the “ERROR” output for a ring modulation type effect.

When no input is provided a DC offset (controllable with the input jack) sets a frequency for the up conversion (which is effectively a VCO), the down conversion acts as a modulation oscillator allowing for a fairly radical form of frequency modulation. Two audio signals can be inserted into the clock input jacks and modulate each other in the same way.
