Introduction

Thanks for purchasing the RF Nomad Eurorack synthesizer
module from Evaton Technologies! The RF Nomad module
allows you to use radio frequency noise and signal sources
as new sonic territory for exploration as audio sources for
your modular synthesizer. The module is a direct-conversion
radio
approximately 9.6 to 10 MHz and decodes the audio as
single sideband.
Various RF noise generators, such as computers, appliances,
etc., as well as shortwave broadcasts and ham radio stations,
can be decoded and used as useful and interesting sound
sources. The RF Nomad's tuning can be varied under voltage
control, allowing LFOs, envelopes, and even audio sources to
modulate the tuning parameter in real time. In short, the RF
Nomad puts those classic squelchy, squealy, hissy sounds of
a shortwave radio into your modular!

  • Page 2 Connect the supplied ribbon cable to the 16-pin dual-row header connector on the RF Nomad. Note that the red stripe on the cable faces the bottom of the module, and the board is marked “Stripe” next to the pin where the stripe should go.
  • Page 3 Audio Gain Operation Operation of the RF Nomad is fairly straightforward -- plug in the antenna, and slowly turn up the RF Gain knob and Audio Gain knob until you hear something, and tune around with the Tuning knob. The RF Nomad does not...
  • Page 4 “duck talk”. Have fun exploring this interesting mode! If no RF signal is present, the RF Nomad can also be used as a sort of noise generator. Just turn up the RF Gain and Audio Gain knobs until noise is heard...
  • Page 5 RF Nomad as percussion: Tune the RF Nomad between stations, so you hear static. Use this as a noise source for a percussion patch. For example, patch Audio Out to the input of a VCA. Then, patch an AR envelope generator to the CV input on the VCA. Now, when you strike the envelope generator, you hear a snare / cymbal sound from the output of the VCA.
  • Page 6 Damage caused by incorrect power supply connection, incorrect power supply voltages, lightning discharge, or other causes determined by Evaton Technologies to be the result of abuse or improper application are not covered. Evaton Technologies assumes no liability for consequential damages caused by the use of this product.
