67 Royalty-Free Audio Tracks for "Shortwave Radio"

Made using the online remote shortwave receiver of university of twente in enschede holland:http://websdr. Ewi. Utwente. Nl:8901/made in the part of the 20-meter ham band where psk31 is the dominant digital mode, with the receiver deliberately mistuned, in fm mode at it's widest setting to get a mishmash heterodyning sound.

Noisy interference caught in the short wave during the eighties and recovered of recordings in casette. First fragment of the package "onda-curta".

Lofi radio sound recorded with 3 eur cheap radio unit. Recorded with tascam dr-22wl. ---in case you use any of my sounds, i will be happy to be informed, although it is not necessary. Recorded in 2018.

Following the latest ‘dare the community’ i’ve finally hooked up my dirt cheap rtl software radio dongle to the formerly disused ‘masthead amplifier’ on our roof. Here are some english truckers(?) chatting over cb radio. They seem to be talking about one of their mates growing a beard and suggesting they ‘give him a quran’.

A data transmission sound or something recorded from 14664. 8 khz. It's probably a weather transmission.

Ham radio amateurs. Weak signal with much statics. From july 26th 2017, 5. 15 pm utc, 14. 237 mhz usb 20m.

Strange high piched signals following some pattern. Any idea what it might be?. 2016-12-15 16:46 gmt at 7041. 5khz. Recorded with the website of the university of twente in the netherlands using the built in recorder. Http://websdr. Ewi. Utwente. Nl:8901/.

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.

Using a variety of 1980s radios connected via a headphone output to the computer, i tuned in - across the entire bandwidth - of the mw and lw channels. I also captured the static hiss of those bands, 'dead air'. There are small clips of various stations along the way but i was looking for that 'tuning in' sound that was so familiar when radio was the central part of every teenager's life.

Amateur radio station w1zy, from rhode island, calling cq on 40m ssb. Bill is an experimentalist ham who uses 2 aluminum phased vertical antennas on a salt marsh. His signal is always strong and his audio a pleasure to listen to.

I bought a portable sw radio for about £2 from a local flea-market, hoping to pick up some interesting radio stations from around the world and maybe some "spy" numbers stations if i was lucky. Had a quick scan this morning and stumbled on this nice clear station, sounds russian - most likely the end of the broadcast and wrapping up with a repeated code to indicate end of transmission.

A testpicture which shows a greyscale in sstv using mode martin1. Sstv stands for "slow scan television". Sstv is a kind of modulation to send a frozen picture enclosed in a transmissionchannel normally used for speech. This allowes to send pictures directly, for instance, on shortwave.

A simple sine-generator piped through a slew of wacky effects automated with randomized lfos. I added some cabinet emulation to give it a 'living room' feel but left it dry enough to add additional stereo/reverb processing. P. S. It loops cleanly. Software: bitwig studio.

Shortwave wide-band digital emission recorded on july 15, 2014 at 15:17 utc in am mode using 2 instances of the online remote controllable short-wave receiver located at the amateur radio club etgd at the university of twente the netherlands. Left channel was recorded below the central frequency, at a frequency of 10187khz, right channel was recorded above the central frequency, at 10191khz. This was an experiment to see if selective fading would create stereo effects, as the lower frequency part of the transmission would be heard better in the left channel, and the higher frequency component would be heard better on the right. I used goldwave to put the separate recordings into 2 channels of the same file, after i synched the recordings by ear at 1/16 playback speed using a set of 2 particularly strong lightning static crashes as a guide, trimming off everything that came before the first strike in both original recordings, then inserting silence in the range of a few milliseconds until the stereo separation was as close to zero as i could get it. I wasn't as successful at that as i've been with experiments with voice recordings from simultaneous broadcasts on 2 wavelengths that i haven't posted here.

The inspire project (http://image. Gsfc. Nasa. Gov/poetry/inspire/)offers a public continuous source of audible signal in vlf band direct of our ionosphere. In this pack i have extracted a selection of fragments of a minute of duration recorded at 7:01 am (local time) every day during approximately a month. If it interests to you listen more of this material you can connect here to stream:http://icecast. Msfc. Nasa. Gov:8000/inspire.

Stereo recording incorporating 2 recordings made simultaneously on the web sdr (software defined radio) in north east pensylvania (fn21mh) at http://k3fef. Com:8901/and the one at raf hackgreen in nantwich in cheshire (io83ra) http://hackgreensdr. Org:8901/i used the filename of one of the recordings for part of this new dual receivers recording mixed in goldwave and time-synched by ear. Left channel is the pensylvania receiver, right channel is the uk receiver. Heard are various stations working or trying to work w1uuu in massachusetts including stations in the dominican republic, argentina, the ukraine, trinidad and tobago, colombia and florida. Some stations are heard better in pa, some better in the uk. Lots of static crashes heard from late spring lightning storms hundreds or thousands of kilometers away from both receivers. You can find over 100 receivers athttp://websdr. Org/most allow you to record, though some have a 15-minute timer.

This is a precise emulation of the audible time signal broadcast by radio station wwv of the nist in the usa on shortwave. This recording was produced via a program i wrote that emulates the time signal and recreates it from scratch, but it conforms precisely to the specs of the real signal. The only part missing is the voice announcement of the time, which, in the real broadcast, is made during the last fifteen seconds of each minute (which is why the tone changes to just clicks during that time). There are two minutes in the recording, but it should be easy to loop it or otherwise modify it for other durations. Since this audio file was computer-generated from scratch, it contains no noise, but the real broadcast has some static and noise, especially at large distances from the transmitter in colorado. Generated by special software / 48. 1 khz 16-bit stereo.
