A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously. SDR technology makes it possible that all listeners tune independently, and thus listen to different signals; this is in contrast to the many classical receivers that are already available via the internet. WebSDR servers can register themselves automatically on this site, leading to the below list of currently active WebSDR servers.
Anyone can access any of the SDRs listed on this site and listen in.
A directory of shortwave listening frequencies around the world.
Shortwave Listening Tips:
- Listen to Asia and Australia in the morning and listen to Europe at night.
- No SW frequency operates 24 hours. You may not hear anything unless you are listening at the right time, or you may hear another language, or you may hear some other country sharing the frequency.
- Many countries are better heard in non-English broadcasts. Explore the dial and you will hear many fascinating things, including exotic music.
- Some stations only air a few minutes of English; or only in ID announcements (Mexico); or only language lessons (Ecuador).
- Country of origin is shown. Many of the frequencies are relayed from elsewhere. In the case of China, all of them shown below are relays. Don't assume any particular frequency is actually coming directly from the originating country.
- Some major countries no longer broadcast to North America intentionally, such as Australia, Germany, South Africa or the UK. Longer frequency lists for these give you more chances to hear something directed elsewhere.
- More than one station may be involved under some countries, or even outside broadcasts to that country (Liberia, Nigeria, Sudan).
- Many of the strongest signals from strictly religious broadcasters in the US and elsewhere are not shown.
Not really a service manual but a small website on the HTX-200 hand-held shortwave transceiver from Radio Shack.
A wiki for documenting and discussing radio broadcasts - short, medium, and longwave as well as anomalies, mysteries, oddities, and pirate radio.
A worldwide volunteer system of radio hams who provide limited net.access during emergencies so that people can communicate.
The website of an international group of numbers stations enthusiasts. Has a forum, a blog, a podcast (good luck finding the RSS feed), live streams...
This is a site that aims to collect and sort out information about some of the more unusual shortwave anomalies, like UVB-76, the more powerful numbers stations, the XM Whales, and other mysteries. Seems pretty solid, without much in the way of conspiracy, just necessary speculation.
An online noise and sound generator. Has multiple categories and dozens of different sounds, from thunder to to rain to singing bowls, the wind blowing through a canyon, surf sounds, wind sounds in different locales, different voices, and different brainwaves. You can stack up to five of them in a sequence. You can download them, too! Updated periodically, so check back once in a while. The iOS and Android apps are out, too.
Archive of shortwave radio recordings to download.
Just what it sounds like: turn on your shortwave receiver (or drop one of your Conet Project CDs in the player), load up this page, and start crossing off boxes.
