These peaks are created usually by voice transmissions and some occasion non-voice data.
What Software Works With Hackrf 1 Software Rather ThanBasically, an SDR is a radio that processes radio transmissions using software rather than dedicated electric components.And while some components are required (such as an antenna and tuner), the capabilities of an SDR are really left up to the associated software.The first thing I wanted to test was how the unit performed with just the stock (default) antenna.
Ultimately, a radio receiver or transmitter is only as good as its antenna, so I was eager to test how well it would perform at receiving local emergency services. The HackRF itself included dust filters for its 3 SMA connectors to protect them from contamination. The stock antenna is compatible with the SMA antenna connector and has an adjustable swivel that I adjusted to 90. It is also a telescopic antenna that can be extended to about 1 meter in total length. But the adapters will be a useful addition if you already have radio equipment or test equipment that uses the other connector systems available through the included adapters. To keep things basic, I will stick to relying on the stock antenna for today. For this unboxing, I decided to try decoding local public safety services such as police and fire from a Windows environment. Here in the state of Illinois, most of these services have migrated to a trunked, digital system known as STARCOM21 2 3. STARCOM21 implements its radio communications using the Project 25 format (also called P25 or APCO 25). In fact, many other states also use P25-compliant radios, especially in metropolitan areas. This program works with the HackRF system by default, and it also works with other popular SDRs such as the RTL-SDR chipset. Additionally, it can pipe any received audio straight to your speakers, to an audio file, or to a virtual audio device such as the VB-Audio cable input. When installed successfully, it will create 2 new audio devices on your Windows system. What Software Works With Hackrf 1 Drivers Were AlreadySurprisingly, the digitally-signed USB drivers were already on my system by way of the WinUSB generic drivers from Microsoft, and no further installation was needed. For the official binaries and installation instructions, visit the Airspy website at. As a result, nearly all of the FM broadcast band is visible at once. Without going into detail, you can remove this artifact by navigating to: Radio Correct IQ checked. This is where most of the P25 radio traffic in my region occurs, and there are a couple of control stations that transmit continuously. These radios operate at much shorter bandwidths than broadcast FM, so the peaks are much narrower here. There was a third smaller peak between, which seems to be an artifact and not a real transmission.
