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.
A high-frequency electronic discord tone (sweeping around high frequencies) suitable for ringtones and annoying dogs. Also suitable as a sound effect for 'sweeping the dial' on shortwave radio.
Message 1-3 are captured by nasa, but recently even other countries have registered very strong, but short signals. The receivers are masers and the frequencies are in the higher gigahz range. Message4 was from russia.
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.
