Over 400 websites allow you to listen to ham radio online. There are two main “flavors” of technology offering this free service.
- WebSDR with its rudimentary user interface (UI) allows over a hundred listeners simultaneously. This means that their receiver-server can almost always accommodate an additional listener.
- OpenWebRX has a more pleasant-looking user interface. But it allows only up to a maximum of 4 listeners simultaneously. This means that some sites are often full of listeners. You can then be patient and wait for an opening . . . or simply try another site.
Please note: Google has decided to modify its Chrome browser – and Android devices – to *not* allow it to play sound automatically anymore. This means that WebSDR sites are soundless on a Chrome browser!
I recommend the Firefox browser instead. With its unrestricted autoplay of sound, it will let you listen to stations on a WebSDR system. In addition, Firefox is the most secure of all browsers . . . and it’s just as free as the others!
This page only contains “live” links!
The links below will actually take you to sites where you can listen to amateur radio communicating with each other around the world.
The “live” links will let you hear ham radio operators using every imaginable mode of communication… SSB, FM and AM voice, RTTY, SSTV. The list of modes is nearly endless because new ones are experimented with regularly.
The “dead” links have been left in their inactive state to let you know that they might be reactivated by their respective owner. When that becomes the case, I will reactivate the links and you will have access to these reactivated resources.
If you find a “dead” link here, please let me know. I will try to reactivate it. If unable, I will remove it from this page.
WebSDR Lets You
To Ham Radio Online
WebSDR User Interface (UI)
WebSDR (Web Software Defined Radio Systems) was developed by PA3FWM. The software server lets many users simultaneously tune the SDR to different frequencies to listen to. There is an ever increasing number of servers being activated.
When I first posted this page, a few years back, there were only a few active WebSDR servers. Now there are 173 WebSDR servers in operation around the world (updated April 28, 2018).
Here is a small sample:
- VE1BAS receiving station is located in Oromocto, New-Brunswick, Canada. Covers 80, 40, 20 and 17 meter bands.

Wouter says he may put it back on the air, if time and money become available again! :(NOTE: I leave this entry here as a reminder to all that it takes quite a bit of dedication, time and money to put up and maintain a receiving station that anyone can access via the Web to listen to ham radio online… at no cost to the listener!)

OpenWebRX User Interface (UI)
OpenWebRX is Linux software. Just like WebSDR, it enables SDR HF receivers to be operated remotely over the Web. You might find their user interface (UI) more user friendly. It’s a matter of taste.
These receiver-servers make it possible for anyone to listen to ham radio online. It is also possible to listen to other radio broadcasting stations on HF.
The majority of OpenWebRX installations allow a maximum of four listeners.
There were 231 OpenWebRX receivers at the time of writing this article (April 28, 2018). You will find one in most countries of the world.
Here are just a few examples. Be patient. Some of them are often busy!
- 0-30 MHz SDR, K1RA/KW4VA, Virginia, USA
- 0-30 MHz SDR, SK3W, Sweden
- 0-30 MHz SDR, SV1QJG, Greece, Zoumperi,Nea Makri
- 0-30 MHz SDR, AKKY, Japan
- 10KHz – 30 MHz SDR – G8JNJ – South West UK
- 0-30 MHz SDR, SWL/Sailor, Shenzhen, China
- Northland Radio ZMH292 Bay of Islands, New Zealand
- 0-30 MHz HF SDR, VE6SLP / VE6JY – Lamont, Alberta, Canada
- Wellbrook ALA1530 (0-30 MHz), Novosibirsk, Russia
Classic receivers can only be tuned to one listening frequency at any given time. When you land on the page, you will be listening to the frequency that was chosen by the last visitor/user.
Most sites let you tune the radio to a different frequency and listen to ham radio online for a few minutes.
- The Original Web-controlled Shortwave Radio – Drake R8 Communications Receiver (110 KHz to 30 MHz) located in Reston, VA USA.
