Remix of wierd chimes. Wavhttp://freesound. Org/people/kwahmah_02/sounds/250253/which was a recording of a shortwave broadcast in am mode received in usb mode 1khz off frequency. I used goldwave's mechanize feature at 10000khz, then applied low pass filter at 10000 khz to filter out the newly created upper sideband, then i used mechanize again at 9000 khz, which tuned in the recording just like if i had a tuneable receiver.

This is static actually coming from my radio but its plugged into the same cord as my tv & they are very close together. So it's actually interference. Also the proximity of my phone gives more sound (ringy static). That really awesome modulating sound is the moment between clicking the on button & the picture coming on the screen. 2nd try was better after i adjusted the tuner a bit.

Two sennheiser g3 transmitters were set for the same frequency; one of them was transmitting a previous interference recording from my macbook p2 phone output, the other one had no input;the receptor was connected to loudspeakers; the interference would vary as i moved each transmitter around. I recorded the loudpeakers output through the macbook built-in microphone, on audacity. This is a specially noisy part i exported. Not a pretty sound, but may be useful.

Quindar sounds were used by nasa for controlling the ground station transmitters that allowed communication with spaceships through the space shuttle era. Fiber optic cable has made quindar sounds obsolete.

You can read more about quindar sounds at https://www. Hq. Nasa. Gov/alsj/quindar. Html. This sound was generated in audacity.

Recorded radio signal using software defined radio (sdr) around 450 mhz. The sound is the result of demodulating a larger signal using cw-l mode in gqrx and skipping through the band with the signal. Therefore this sound has no real meaning it's just a part of a larger signal.
