If you take away the chance that propagation will gift you with extra lift either on transmit or receive, CB radio can be limited in range (especially if your in a bad location). Even though this range problem can be hard to overcome there’s a way you can easily check out what’s happening on 27 MHz in other parts of the world.

By streaming the feeds from S.D.R (Software Defined Radio) receivers and giving the web user total control over frequency and receive mode, it’s like having a network of CB radios in different locations sending you audio.

Many of the online S.D.R feeds are geared towards the radio amateur and while they have a wide frequency coverage it’s limited to the various HF ham bands. Luckily for the CB user there are a few that have excellent coverage of 27 MHz with all modes available.

S.D.R Feed List

Below is a cross section of the types of S.D.R feeds that you’ll find online and these are taken from one of my favorite S.D.R portals at http://websdr.org/. I’ve done all the hard work for you and listed only the ones from this portal that will allow you to listen to the CB band.

1. University of Twente, Enschede, NL

2. North Germany near Schleswig

3. Russia

4. Cheshire UK

5. Russia/Ukraine Border

6. Croatia

Ease of Use

Operation of the control panel is pretty straightforward with separate receive mode buttons and plenty of ways to tune the S.D.R feed to the right frequency. Getting close to your desired frequency is just a matter of point and click then fine tuning with a series of buttons below the frequency readout. Exact frequencies can also be typed straight into the readout box if you already know what you want to monitor.

Some of the feeds have details on the equipment and antennas used while others only have a minimum of information listed. Software designed radio allows lots of users to connect to one receiver at the same time making the system ideal for streaming over the Internet.

Computer Specs

If your using a computer to do regular surfing of the web then you already have everything you need to monitor and control the S.D.R receivers listed above.

If you have any questions about using these feeds to listen to CB radio, drop me a line and I’ll do my best to point you in the right direction.
