Etherify 1 "soft tempest" demo.Distance is about 10m, through a concrete wall, located in an area with a lot of electromagnetic interference.Receiver is an rtl-sdr with a simple 1/4 wavelength wire antenna, fldigi used for decoding.

The decoding isn't 100% because the software morse code decoder is bad, this would be decoded 100% by a human.
