Firstly, you need to open a terminal and type “rtl_airband -ef”. Now, it is time to start hearing what’s in the sky. In this instance, you probably have set up both, hardware and software. Hear the skies with your new VHF receiver You can make whichever modifications to the configuration file. By default The audio files will be created to "/home/pi/output_airband" Place the config file to the right placeĪfter you download the configuration file, place it to the right folder and restart the device, the receiver will start to record the communication taking place on the frequency. If you see something like that, then just reselect frequencies that you want to follow and consider using multiple SDR dongles)Į. It looks something like that: “ Bandwidth of device 0 - My New VHF Receiver exhausted! Used bandwidth 7.300000000000011 - available 2.4” BUT if the difference between the frequencies is greater than the one you specified in step “a)” then an error message will be given. (You basically can choose to listen to more than one frequency. Choose the frequencies you would like to record. In this case you’ll probably have a bad reception of the controller's voice).ĭ. For example, when you're directly underneath the descend route and would like to eavesdrop pilots’ talk. But in some cases it would be of interest. (Normally you would not one want to pick one that is further than 10km or so. Choose an airport of whose communication you would like to listen to (It will be used for proposing frequencies you could listen to by searching airports that are close to your location. Specify parameters related to the receiver location You can have more than 1 one receiver dongle per your Raspberry Pi)ī. (Note the comments explaining some of the choices you need to make. Hit “Add New” button and hit to confirm your choices (I live in Tallinn, Estonia so the following examples are based on that.And although you can have more than one receiver dongle attached to your Raspberry Pi, the following example assume only one)Ī. We have created some functions that will help you along the way. Modify the RTL-SDR Airband config file.We have made an effort to automate this step so all you need to do is to execute a few commands on your Raspberry Pi terminal window. Install RTL-SDR Airband software and all required utilities.As we described it earlier, you do not do anything here It pretty much has three main parts in it: It’s beautifully crafted open source software that can be found here: The following is based on the instructions given here: Next, software to enable radio signal reception needs to be installed. Instead we’ll guide people to here: Īlright, hopefully by now you have a Raspberry Pi ready to be used. More about the Raspberry Pi project can be found here: Īs the Raspberry Pi project has produced really easy to follow instructions on their homepage, we are not going to give exhaustive instructions here. The first step to get started is to set up the Raspberry PI, a versatile single-board computer that can be used for developing pretty much anything. Monitor and keyboard if you want to set-up the RPI without LAN cable.USB extension cables for the SDR USB sticks.Luckily it is really simple and a person interested in eavesdropping to pilot-controller dialogue does not have to be an expert in radio equipment. See LiveATC.Obviously one needs to have the voice recordings in order to be able to do the conversion and this will be the focus of this blog post - we’ll take a look at how to set a VHF (very high frequency) receiver.
