3 recordings of various rfis made by refreshing the radio signal on myphone and putting it close to my microphone. First sound however, was coming from my electric piano, because my phone was on top of it.
I foudd this frequency, between 4450 and 4475 khz whilst going through channels on radiosdr. Org. It sounds a bit like a printer and then lower down sounds like a laser. Sorry for the sound of me pressing the keyboard, my laptop has an internal microphone so this was picked up.
Scrolling through various shortwave frequencies, caught a tone that slowly turned into a beep with rising tempo. Radio used was a grundig yacht boy 207 with a broken antenna, recorded on a tascam dr-05x.
Exploring the medium wave frequencies. Everything here sounds creepy. Radio used was a grundig yacht boy 207 with a broken antenna, recorded on a tascam dr-05x.
A long series of granular synthesis glitch-style oddness, could be used for interrupted transmissions, tuning in an old radio, galactic strangeness, and the like.
I've scanned the radio frequencies with an old radio and recorded with my tascam dr-05 via the headphone jack. You can hear some weird looping patterns and sound fragments from random radio stations.
Scrolling through various shortwave frequencies, caught couple tones among the noise. Sounded like sad horns. Radio used was a grundig yacht boy 207 with a broken antenna, recorded on a tascam dr-05x.
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.
Dl0ksc in cw qso of mar 10th, 2012, at 11. 50 utc on 10116 khz. Stable high frequency but multiple tone - spectrum. Audio frequency changes are due to my tuning of trx to hear multiple tone.

Different frequencies of sounds from the radio transmission in the basement carpark resembling that of an alien-ish futuristic noises. Recorded using edirol r-09, 15cm from speakers.
Radio frequency interference at the 1200 khz mark of the a. M. Band, caused by varying proximity to a laptop computer. Very active and obnoxious high-pitched static and squeals.
Static with a sort of jackhammer pace at 107. 9 on the fm side of the radio dial. Recorded from a digital tuner, with a quick flip to 87. 5 fm then back to the 107. 9 static. Definitely qualifies as noise.
