Grab a NOAA All Hazards Weather Radio broadcast and stream it to the world.

NOAA ALL HAZARDS Weather Radio transmitters operate with power from 100 to 1000 watts, with a reception range of 'city blocks' to 40 miles if everything is perfect. It often isn't for our location, hardware budget, etc. The frequency used is between Standard VHF television channels 6 and 7...and is narrow band FM with a maximum frequency deviation of 5 kHz.

Stream Quality so important, that several PWS team members audit the site consistently for quality and offline streams. We show you any last update times, and 'flag' any streams with issues, giving both users and providers the last observed streams status, or any station listing updates.

When the team sought NOAA/NWS approval, we agreed to strive for the best possible monitoring and presentation of NWR broadcasts. —Further Discussed and illustrated on the STREAM QUALITY page.

1. PC or something similar.
2. Weather Radio Receiver e.g. Midland WR300
3. Audio cable lash-up from receiver to PC (whatever).
*Radio may have only 'mono' output from line out / earphone plug...
Just ONE of several possibilities:
*Mono to 2 Channel splitter, — Something like this works well.
*Audio Cable to PC (whatever) Line In — something like these
*Some encoders allow single channel to stream as both channels, whatever produces L and R audio.
4. Raspberry Pi + SDR ? — YES! — Tim Urberg has posted scripts and documentation on Github "RTL SDR Darkice Scripts — Discussion and inquires

Encoder (or device) which creates good to excellent 2 channel MP3 audio from your WxRadio output; at 24-40 Kbs (16 Kbs may produce minor aliasing), streaming both channels, with -6 to -3 db average, for best overall presentation. See STREAM QUALITY

A Quality, Reliable Stream
Begins at the Antenna

— Quality starts with reception — If you've a lousy signal, no amount of fancy software or requests for help will improve it... even adding one of those so-called 'extension' accessory antennas may be a waste of money...
BUT — an external ¼ λ ground plane antenna can be dramatic — here's a quick and dirty-- if you can hear a signal, even noisy, this little home built ugly will clean it up.

(...any doubts, click the image, and listen as the antenna is connected to the receiver)

Stream it yourself locally

Let's Do It


— Encode your stream as MP3 audio
— 24k to 56k Bit Rate. Higher bit rates just waste bandwidth on narrow band FM audio
— 32k is about optimum. A bit rate of 16k or less will definitely produce aliasing.
— "Samplerate" of 22050K is adequate as opposed to 44100...this is narrow band audio.


— Stream BOTH L & R Channels! (stereo)

Your audio source may be single channel (mono) L or R. Some encoders allow 'splitting' on set up in some fashion, some do not. Simple mechanical solution is to use a "mono" to "Stereo" "splitter" adapter, which takes single source and splits to two channels for input to computer, or devices L and R line inputs-'both channels".

If your encoder has an option for "Joint Stereo" try that first, it may produce better stream quality than "Stereo". or "Mono" in some situations and configurations.


— Set adequate input and Encoder volume levels! This is crucial!

If your encoder has DB meters/etc, set average peak at -6db to -3db if possible. Don't 'listen'... watch. If there is excessive volume, you'll blast your listeners with a sudden high level stream they're not expecting. Too low a volume level they have to crank up their volume, then the next station is peaking "in the red", and that wakes up the baby ... and Mama's PO'd, So, set levels visually, rather than "it sounds good to me!".

Gotcha! Signal Input On most configurations, 'MIC' input typically expects lower signal levels than a receiver's earphone or line out signal...can result in much higher signal levels, especially if MIC has a 'boost' setting. Use the LINE Inputs if available!

Getting it Live on the Web

Simple is Better

We've an Icecast Server just waiting for you, courtesy of a PWS friend, Crushed Box Software. Chris has made it real simple, free, and reliable...

Simply point or change the encoder mp3 output to
User: source
Password: WxRadio2014
There are illustration links on the "butt" and "M3W" encoders suggested above.

Stream it Yourself

This means the streams are accessed directly from your device, within limits of your bandwidth, and number of 'concurrent' users you can handle... Setups vary, and such things as 'port forwarding' come into play... so we won't spend any time with that... follow the setup directions for your setup and situations.

Finally: Register Your Stream!

Submit your stream to NOAA Weather Radio Org

Use the 'Submission Form."
Select "New Stream" and fill in all the appropriate fields.

Cheers    Welcome Aboard!     Save a Life!

...and remember:  — Excepting a fault in a NWR transmitter —  
Quality and Reliability is the responsibility of each provider.
A daily, quick, online check of your stream will prevent many 'dead' or 'disabled' feeds.
