And that's why frequent testing of your personal streams is necessary.

Thanks!

Ok... a few 'third party' stream servers seem to be modifying source URLs...
.... and we'll have to track down those changes...

1.  If you've subscribed to QRA for a stream, you'll have to cancel your old one and add subscription for revised URL,
AFTER WE GEAT IT UPDATED (Where We Can)
2. If you're using the NWRorg (Ken's)Active scripts on your website, they should Update to any new URLs that we correct... usually at about a hour, if you access your site streaming page.
3. To Minimize this, which sometimes happens with the 'Non-NWROrg' servers, you might point your stream to the
WxDNS server that supports the NWROrg site,
See  http://noaaweatherradio.org/howto.html
and if you add or change your stream access url (mountpoint) be sure to submit a change or update form... we can process quicker, and it will automatically verify if your ask for QRA, and we have a correct stream from the Submit Form..
http://noaaweatherradio.org/addstream/addstream.html

Bear with us... it will take awhile, to check these, and there is no guarantee that, once we revise our database, that it will remain accurate, if you're using a third party server which we are referencing....

We believe we've updated those 'third party' access links...
If You're using them, PLEASE Check the NOAA Weather Radio ORG' site player listing for
any errors in your streams...

If you're using Ken's NWROrg script template on your website, that script should be beginning
to automatically update with the corrections...

Something going on with that third party... we'll wait until whatever's happening to 'shake out',... appears they've got something going on with server mountpoint redirection... PITA

Thinking very seriously about dropping them as resource... we're NOT going to be a WU problematic clone.

3rd Partyt Stream servers...
« Reply #805 on: April 01, 2018, 08:46:35 PM »
As you may be aware, some issues with stream access on certain third party servers.
At this time certain feed access links have been removed
from the NOAA Weather Radio ORG website.  This will also affect the
web templates you may use on your website, as that script updates
.

As stated at http://noaaweatherradio.org/howto.html


This affects approximately 53 streams, and we hope it is temporary.
We recommend you either 'stream it yourself' or preferably point an encoder
to the server recommended in the above 'how to' link.

Additionally, we will shortly upload some additional 'free' encoders that could be
used, some of which allow you to point to multiple servers, in addition to the ones
already listed.
The website will be updated with that info, and we'll post links here in addition.

We simply don't have time and 'budget' for this project to chase stream sources all over the place, and regret this action, as stated, we hope it will be temporary, but
your best option to remain on NOWRorg is to also point your stream to our suggested server...

Remember this is a Volunteer, non-commercial WxForum Community project, and you folks are special. You should be proud of what you've helped accomplish...

Hey all
Brandon Hennis here.
I am offering as a replacement which should work, an icecast server.
Broadcastify feeds as were noted by the previous who were posting here have been changing their source URLs, so thus the feeds appear they keep not working.
Here's the icecast server, you are all free to use it, if sources was configured correctly 300 mountpoints are available.
bhsprn.tk
port 8000
password smokescreen
mountpoint /callsign or /cityname
Efforts are in the works to eventually dedicate a computer to streaming fulltime NOAA Weather Radio KZZ52 on 162.525 MGZ, originated by NWS Omaha, and serving southwest IA
Waiting for equipment repairs to be completed and then that will be accomplished.
Regards
Brandon

Thank You Brandon!
Save A Life!

Suggest you EDIT your post, to remove that 'public' login info for your server...
(otherwise you may have strange 'users' on your limited server)
then use the "Submit"/"Contact" form at
http://noaaweatherradio.org/addstream/addstream.html
(that way the entire NWROrg Team will get a reference copy)
and it will go in our archive info resource automatically)
With the appropriate info... and when we update the 'How To" page, shortly,
we can list you as an alternative / additional server

What's good about 'additional' severs, is many encoders can provide streams
to multiple servers, in addition to our 'partner', WxRadio DynDns' recommended server.
We'll be adding a couple of suggested 'multi stream' encoders to the site shortly, also.

Bear with us!

No problem.
I didn't quite see the name of who sent the message, but thank you for allowing me to post up here, and I'll deffinately do my best.
Is there anyone who could possibly do some testing for me.I'd like us to get 10 people up there, and if we can start with these initial 10 for a couple days I'm thinking maybe from Thursday to Saturday morning, thenwe can considerthe bhsprn nwr server officially launched.
If you all would like I'll be happy to see if I can get others to stream their NOAA Weather Radio Broadcasts for some of these areas too.
noaaweatherradio.org is amazing, and I'm willing to do all I can.
Thanks.
Brandon.
PS. I'm totally blind.
Thanks to Ken for helping me get signed up here.

Everything sounds good over here, audio is perfect.  I'll update you on how things sound for sure.
One note, if you are monitoring noaa weather radio wxl93, I hear some overmodulation on that one and also on the kec42 audio as well, some high levels.
Just thought I'd let you know.
As for bhsprn.tk, audio is perfect, keep it rollin'.

New Station!
This is in test phase but, NOAA Weather Radio KZZ52 is streaming on http://bhsprn.tk:8000/kzz52!
It serves west central IOWA, on 162.525 MHZ

Great... Now, We've added KZZ52 to the NWR listing...
BUT
The provider should go to
http://noaaweatherradio.org/addstream/addstream.html
tick the New Stream entry
and 'submit' the information as a new stream, so we have
the info available...
We currently don't monitor Brandon's server for updates and errors,
and ALL stream providers should submit their stream, especially
if they would like the Quality, Reliability tool access... we need their
correct stream info through the Submit Form
to validate against a QRA Request. IMPORTANT

If you really wish to participate in the NWR project, we recommend a
thorough check of the pages on the site relating to 'how to', 'Quality'
'Reliability' and even the 'about' page...

For those streaming, the test is successful.  bhsprn.tk can now be used as a permanent location.  I was just checking the feeds this morning again and they are working perfectly.
Consider that a personal official launch from the server owner of bhsprn.tk
You guys rock.  Thanks Doug, and everyone involved, the test is now, a permanent work, and yall are free to keep your streams up there.
Thanks for contributing.
Let's keep these streams coming!

Glad to see wxn82 back.  Too bad we don't have wxl76, wxl75 or wxl74 streams up.
Has anyone heard anything from Hastings and Kearny for the streams?

I had 3 things and points with that noise reduction.
A, noise can be reduced, but with 3 drawbacks.  Number 1, by reducing the noise, if you have a band opening it can change the clarity of the audio.  Because remember when two or more station is on the same frequency you hear that modulation and the other station in the distance.  The noise filters can only do their part to press away different noises, but it can't prevent them entirely, without preventing the audio.
So let's use the example of the 24 second clip.  In the first example, the flat audio, which by the way, if someone used a bit of treble reduction the high hissing sound could be delt with that way.  The second part of the clip though registers that, if a band opening happens, and say for example on the frequency of kzz48, you hear 5 other stations, eventually the noise filter may get confused as to whether or not you are canceling out voice, or noise.  I guess the one thing that would be a good test is to make the signal gradually weaker to see how much the threshold is, before the sound is blocked.
Item 2, separate notice, KZZ52 is back to streaming.  I had to correct an audio issue with a patch cable as the jack I was using to run the audio through was trying to outsmart me, so I moved the patch cable to my microphone input jack on the computer.  Seems to have solved the problem, minus the detail that thankfully I'm streaming mono since the patch cable is mono.
Just an interesting question, does anyone know if the web based software defined radios are accessible to the blind?
Just wondering.
I hope my audio insite gives you something to look at.
Ssorry if I missed something, I'm doing this on literally no sleep.
Thanks
Brandon.

bhsprn.tk is launched
Thanks to doug, from Omaha, testing using the KIH61 feed, and frankfortweather.us for the Owenton test of NOAA Weather Radio kzz48,
All feeds which were streaming to broadcastify and or anyone else who wishes to stream their weather radio is now free to use it.
Here's the details again for those who have joined us late.
The hostname is, bhsprn.tk
The port is, 8000.
The password is, smokescreen
The mount point is, /callsign or /cityname
Note, though I did list those mountpoints If you wish to use a different convention, I am perfectly fine with it, such as /nwr.org/kih61
Please feel free to make use of the server at any time.
It is now ready for full duty cycle and use.
Thanks Doug and friends for testing.
You may stream as normal streams now.
For a complete listing of current feeds on the bhsprn side of the NOAA Weather Radio streams, you might consider the url http://bhsprn.tk:8000
If you wish to email me in a respondible fassion, please use kc0usm@gmail.com
Unfortunately the captia prevents me from being able to reply to inbox messages on the wxforum.net side of things.
Thanks a million
Brandon

Brandon, we have two pages on the sited devoted to quality and
reliability issues, while not web accessibility compliant as yet...

There is no 'catch all' noise solution... especially when it may be difficult to determine if 'hum' for example is 'local' or the fault of the transmitter for example...

There are some basic things that can be done, simply, or with a little
effort... and what we hope to do is make another tool available in the
'software' / encoding line....

First mistake we may make is assume this is 'high fidelity' audo... it is not.
The bandwidth is approximately 3800 HZ . not 15kHz as in FM Radio. So if we encode at a 15Khz audio bandpass, we're just asking for high end noise.

When this tool goes up, you'll se the 'bandwidth' in an example configuration limited from about 200Hz to about 3600Hz.

Working on 'tutorial' and 'how tos' currently.

Since Tim and I both have PI stations, we worked on a similar solution.

In the playback software, we used a "sinc 150-2.5k" option.  That basically only allowed the frequency of 150hz through 2.5khz.  In the darkice config file, there is a similar lowpass and highpass filter options I have set to the same.  I had 60 cycle hum in my stream originally.  Also some higher hiss.  This helped a lot.

I also ran a program to test the radio crystal.  It has some error in the frequency.  In the playback software, you can correct for that.  That helps the radio tune more precisely to your frequency.  It wasn't as much of an improvement as the filter, but it also helped.

I stream off of two PI's both using darkice.  One PI I use and audio dongle and Midland radio.  The other PI has an SDR.

Tim helped me out when I originally set them up in February of last year with a lowpass value of 3500.  No highpass value.  What are you using for your lowpass and highpass values in the darkice.cfg file?

Thanks,

Doug

Makes sense.
I tried to submit the kzz52 stream a while back but haven't seen it up.  Have fixed the audio problem that was plaguing the thing for a few hours, moved the patch cable as noted in my last post to a new spot on the computer, the mic in and then adjusted the micc in accordingly to avoid high levels.
