NOAAPort Signal Changes March 2011

In March 2011, the NOAAPort signal will change from DVB-S to DVB-S2.  That means if you are using the Novra S75 receiver, you will need a new receiver.  The Novra S200 will work with both DVB-S and DVB-S2.

This change will increase the data rate from 10.24Mbps to about 30Mbps.  There will be a 30 day window between March 5, 2011 and April 3, 2011 when both signals will be present.  After April 3, 2010, the DBV-S signal will be discontinued.

You can read more from this data management notice.

If you use NOAAPort, you need to plan on purchasing a new receiver.  Novra is offering a discount to existing S75 owners.

NOAAPort Update

Here is the latest information announced in ADMNCF.

ADMNCF

Subject: AWIPS SBN Status Update

On Sunday December 5th at approximately 2100Z, the AWIPS NCF moved all AWIPS NWS sites to a temporary frequency due to SBN interference problems that were found on the original AWIPS SBN frequency.

During the past 24 hours, the NCF has worked with the satellite provider, GLOBECOM, to ensure all interference problems experienced throughout the weekend have been corrected. Today between 1930Z and 2000Z, GLOBECOMM will perform intrusive testing on the original AWIPS SBN signal.

All AWIPS offices are still currently using the temporary AWIPS SBN frequency and will not be impacted by the intrusive testing that is taking place. External NOAAPORT users that are currently using the original AWIPS SBN frequency may experience brief data outages while testing is taking place.

Tomorrow, December 8th between 1400Z and 1500Z, the NCF will re-point all NWS offices back to the original AWIPS SBN frequency. The switch back to the original AWIPS SBN frequqncy will be done remotely by the NCF and sites should not see any downtime as a result of the switch back to the original frequency. Once all sites have been re-pointed back to the original AWIPS SBN frequency, another admin message will be sent.

On December 8th at 1600Z, the temporary AWIPS SBN frequency that was established will be terminated. Any external NOAAPORT users pointed to the temporary AWIPS SBN frequency will need to switch back to the original AWIPS frequency before 1600Z on December 8th.

Thank you for your continued patience while these issues are being resolved.

All NOAAPort users should switch back to 1193.5 before December 8th 1600Z.

NOAAPort Receive Problems

There have been significant receive problems with the NOAAPort signal today.  After lunch my Novra receiver was not able to lock onto the signal at 1193.5 mhz.  Around 8:00 someone announced that the frequency may have changed.  Our friend Dave, KG4YZY, found out that the new frequency was 1138.5.  After updating the Novra with the new frequency, it is now locked and receiving data.

I don't know if this is a permanent change or only temporary until the original problem is resolved.

First Polygon Siren Activation occurred today in Autauga County

The first polygon siren activation, using WxSiren Controller, occurred today in Autauga County.  Here is a copy of the automatic siren activation message.

Windows not visible after screen resolution changes

Several users have run into situations where some of the Weather Message windows are not visible after changing the screen resolution.  I have added code to the programs to check and see if the program's window is on one of the connected monitors.  If the window is off screen, it will be moved back on the screen.

Right now this code works immediately with child windows.  If the program's primary window is missing, the user will have to stop and restart the program.  When it restarts, it will be visible.

In the past, users were required to edit the registry or an ini to get a missing window back.  This will save the user and me alot of time.

Weather Message 3.8 Beta 1

I am in the process of uploading Weather Message 3.8 Beta 1.  This release of Weather Message will using the Microsoft.Net Framework 4.0 if it is installed on the computer.  I recommend that all users install Microsoft.Net Framework version 4.  You can install the 4.0 framework from this link. 

Note:  If you install the version 4 framework, make sure you install the full version 4 framework.  Microsoft made a version 4 client profile that does not contain all of the version 4 assemblies.

All of the programs are compiled against Microsoft.Net framework Version 3.5.  Most likely they will be compiled against the version 4 framework before 3.8 is released.  The current beta will allow us to evaluate the programs using the version 4 framework.  Initial tests did not reveal any problems.  The version 4 framework contains a number of enhancements that may improve program speed and/or operation.

Several of the programs in this release of Weather Message will not work on Windows 2000.  I do not recommend installing Version 3.8 on a Windows 2000 computer.

NWS Products and Services Reference Guidebook

The NWS Products and Services Reference Guidebook can be found at this address http://www.weather.gov/om/guide/ This guidebook contains some good general information about the NWS products and services.

WxMap - Speed Increases

After researching an issue in WxMap, I ran some performance tests to see if using a county's database identifier was faster than finding the county by center point.  The current operation, in general, is faster than database access.  If the county appears in the database first, the database method is somewhat faster.

I did some research on my mapping component vendor's website and discovered that using 'rtree' indexing would make the spacial operations faster.  I thought I had already enabled that option.  Upon checking I did find that I enabled that option on each layer.

When I read through several posts, I discovered that rtree indexing should be enabled after adding the layer to the viewer.  I gave that a try and was blown away.  The speed increase is remarkable.  It is well over 100% faster than the old operation.  Users will definately notice the difference if they are alarming the entire United States.

This operation does create an additional file in the Map directory for each map layer.  You will notice a new file for each layer with the extension 'rtree'.  The files are not really large and are created the first time the map program is loaded.

WxMap now supports a dynamic map legend

WxMap now supports a dynamic map legend.  The map can continue to be static or two versions of dynamic.  Dynamic 1 only displays products that are checked with the show in legend option.  Dynamic 2 displays all active products.  Here are examples of the legend.

These two map legends are dynamic.  The second map legend displays 'No Active Products'.

WxLoader and the PRO-Lite TruColor II

WxLoader can now upload text to the PRO-LITE TruColor II scrolling led sign. Here is a link for information on this sign - http://www.pro-lite.com/indoor-singleline-plm20.htm

Using WxLoader, the sign can read "A Tornado Warning as been issued for the following counties in Alabama, Tallapoosa, expiring at 9:00." (It flashes the word Tornado in red.)

This is a picture of the Pro-Lite PL-M2014RV6.

Weather Message 3.7 Released

Weather Message V3.7 has been released. You can download the update at http://www.wxmesg.com/downloadsnet.htm. For information on what has changed in this release, please read the release notes.
There are over 80 changes in this release. Here are some highlights.

• Updated support for Facebook and Twitter.
• User defined products.
• Updated map zones (You will need to download the map update).
• WxMap can now embed an image in a saved map image.
• WxLoader supports the Pro-Lite LED sign.
• See the release notes for a complete list of changes.

Thanks for all of your suggestions, bug reports and assistance with the software. Work will begin on version 3.8 right away. Watch the beta page for updates.

Suggestions for 3.8

• WxMap add a dynamic legend

WxDataSave, WxLocal and the Retransmission applications have been respectively released along with Weather Message 3.7. If you are using any of these applications, they must be upgraded at the same time you upgrade Weather Message.

Note: I have a large number of pending requests. I will begin to address these over the coming months.

Note: I am working on a new Weather Message website. I hope to place the new website on-line by the end of this month. This change will ultimately allow users to login and obtain their registration codes. It is based on a popular content management system and will allow me to quickly update the website.

WxLoader - Interfaced to the Pro-Lite Scrolling Led Sign

After 5 months, I have gotten back around to testing my new Pro-Lite II scrolling led sign.  After I learned how to program the unit, I change WxLoader to support sending text to the Led Sign.  It works great.  I am still working with the colors so that I can make watch and warnings look different.

This is a picture of the Pro-Lite PL-M2014RV6.

WxMap - Adding a logo to the saved map image

The next release of WxMap will allow you to insert a user defined logo in the saved map image.  This allows you to personalize the image that you use on websites.  The Map Save tab allows you to specify the location on the map.  The logo must be saved in the same directory as WxMap.exe or WxMapNet.exe, generally c:\Program Files\WxMesgNet, with the name WxMapLogo.png.

If you create the logo with tranparency the map will show through the logo.  I created a test logo that will go out with the next beta.  Here is what it looks like this:

I used Paint.Net to create the image and make the background semi-transparent.

EMWIN Success Stories

I am collecting user testimonials on how EMWIN has been used to "save the day". If you use EMWIN to protect citizens, save life, and property, I would like to hear your story.

With your permission, I will list your testimonial on www.emwin.net for others to read. We need to let others know the value of EMWIN.

You can email your testimonials to me or post them here on the Weather Message Yahoo Group. If you do not want your name or agency included with your testimonial, please let me know. I will respect your wishes.

Weather Message Support for Windows 2000 will end soon

Weather Message will no longer support Windows 2000 after version 3.7 is released.  Microsoft has dropped support for Windows 2000 in the Microsoft .Net Framework version 4.0.  I am planning on moving the software to the .Net Framework 4.0 version with the 3.8 beta. 

Here are the system requirements for Microsoft .Net Framework 4.0.

Supported Operating Systems:  

• Windows XP SP3
• Windows Server 2003 SP2  
• Windows Vista SP1 or later
• Windows Server 2008 (not supported on Server Core Role)
• Windows 7
• Windows Server 2008 R2 (not supported on Server Core Role)

Supported Architectures:

• x86
• x64
• ia64 (some features are not supported on ia64 for example, WPF)

Hardware Requirements:

• Recommended Minimum: Pentium 1 GHz or higher with 512 MB RAM or more
• Minimum disk space:  x86 – 850 MB, x64 – 2 GB

Twitter and Facebook Support in Weather Message

Weather Message Beta 7 includes the new Twitter authentication changes.  This release also introduces Facebook support.  The F1 help's supplement section contains example setups for Twitter and Facebook.

Note:  After discussing the facebook implementation with one user, I discovered that you can only post to your personal page.  If you manage multiple facebook "pages", the current implementation will not post to those pages.  I have been testing changes that will allow you to post to any page that you administer.  Those will be available in the next beta release.

Update:  Beta 8 now includes support for multiple facebook pages.

Twitter Changes

Twitter is changing their authentication mechanism from "Basic Authentication" to "OAuth".  Twitter provides this description: "OAuth is an authentication protocol that allows users to approve application to act on their behalf without sharing their password."

Twitter will be disabling Basic Authentication at the end of this month.  For Weather Message to continue sending tweets, I will need to make some involved changes.

I have moved this item up on my priority list and will try to add this capability to Weather Message.

WxLocal - Speaking the local weather conditions

WxLocal is receiving the ability to speak the local weather conditions.  The program can also write out the speech to a wave file.  It sounds good with the Windows 7 text to speech processor. 

I sure would be nice if WxLocal would send that wave file to Weather Message so it could upload it to a website and/or send it on to the clients to play.

The ability to play wave files in the Message Client would be nice addition.
