This page has information about my online stream of NOAA Weather Radio KHB-36. This is the NOAA Weather Radio station that is broadcast by the National Weather Service office in Sterling, VA, and is transmitted from near Manassas, VA. The coverage area includes much of the Washington DC Metropolitan area. This feed regularly receives a large amount of listeners during severe weather events.
If there is no audio on this feed, please first check the NWS Public Information Statement to make sure that the transmitter isn’t offline for maintenance or other problems. If there is a long-term outage that is out of my control, I will attempt to put up an announcement on the stream so people are aware.
Listening to the feed
I’m hosting the stream through my own streaming server. The link below to listen in your browser will open a new tab, while the media player link will download a playlist file that can be opened in your media player of choice. I’ve tested the “listen in your browser” function in Microsoft Edge, Mozilla Firefox and Google Chrome.
Making the feed
This feed is powered by an AirSpy software-defined radio. It’s connected to a high-gain VHF amateur radio antenna. The audio is routed to an open-source utility called Broadcast Using This Tool, which is encoding the audio and sending it to the server. There is an audio filter being used that is built into the SDR decoding software, and removes a large amount of the static that would otherwise make it harder to hear.
I switched from a separate scanner to a software-defined radio because the computer can now power the radio receiver (it connects via USB), allowing me to not have to power a scanner and also cleaning up some extra cables from my desk. I also get control of the RF signal that the software is decoding. This allows me to use only the minimal amount of gain necessary to keep the local transmitter clear, but helps keep more distant transmitters at weak enough levels that they are considered noise, and thus filtered out.
This audio stream is NOT to be used for protection of life or property! You should NOT rely solely on this internet stream to receive watches or warnings. Instead, you should have a dedicated NOAA Weather Radio receiver which will alert you 24 hours a day to hazards in your area. This internet stream is provided as a convenience and is not an authoritative source for official watches, warnings or advisories — those should be obtained directly using your own NOAA Weather Radio receiver. Please do not rely on this page or audio stream as your only source to hear NOAA Weather Radio. When you need it most, storms may cause power or internet outages that can affect the availability of the stream.
