NOAAPort - Novra S200 is the wrong receiver

After purchasing the S200 receiver and installing it here, I have now learned that this is the wrong receiver.  What I really need is the S300 receiver, which not currently available.  Apparently NOAA wanted to use VCM (variable coding modulation).  The S200 receiver does not support this capability.  Novra will releasing the S300 sometime between now and April.  I understand that the cost of the S300 is around $699.00.  There is a discount for current Novra S75 and S200 users.

Due to this situation, NOAA is delaying the DVB-S transition by 45 days.  Here is the text of the latest message.

WHAT - SBN/NOAAPORT EXPANSION AND HARDWARE UPGRADE DATE - JANUARY 19 2011 

NOTICE - 002 PLANNED IMPLEMENTATION DATE - MAY 18 2011

---------------------------------------
UPDATE OF NOTICE 001 TO IDENTIFY RECEIVER SELECTED FOR USE BY THE NWS AND DELAY OF THE PLANNED IMPLEMENTATION DATE
---------------------------------------

THE AWIPS PROGRAM OFFICE IS CONTINUING WITH ITS PLANS TO EXPAND THE BANDWIDTH OF THE AWIPS SATELLITE BROADCAST NETWORK SBN/NOAAPORT FEED FROM 10.24 MBPS TO ABOUT 30 MBPS IN MAY 2011.

AS PART OF THIS EXPANSION, THE SBN/NOAAPORT SIGNAL WILL BE TRANSITIONED FROM THE CURRENT DVB-S STANDARD TO A MORE EFFICIENT DVB-S2 STANDARD.

TODAY, THE NWS AWIPS PROGRAM AGREED TO A DELAY OF 45 DAYS TO  ALLOW MORE TIME FOR THE NOAAPORT COMMUNITY TO PREPARE FOR THE TRANSITION.

THE AWIPS PROGRAM HAS SELECTED A DVB-S2 RECEIVER FOR THE SBN/NOAAPORT EXPANSION PROJECT. WE WILL BE IMPLEMENTING A SINGLE DATA STREAM THAT WILL REQUIRE VARIABLE CODING MODULATION -VCM- OVER MULTI-PROTOCOL ENCAPSULATION -MPE- WHICH IS SUPPORTED BY OUR SELECTED RECEIVER.

WE UNDERSTAND THAT ONE OR MORE OTHER MODELS OF DVB-S2 RECEIVERS MAY ALSO BE SUITABLE. THE RECEIVER SPECIFICATIONS CAN BE FOUND ON THE NOAAPORT WEB SITE.

TECHNICAL SPECIFICATIONS FOR THIS PROJECT ARE BEING FINALIZED AND WILL BE MADE AVAILABLE VIA THE NOAAPORT WEB PAGE AS THEY ARE COMPLETED.

IN PREPARATION FOR THE TRANSITION, THE NWS WILL BE PROVIDING A 30 DAY WINDOW STARTING APRIL 18 2011 UNTIL MAY 17 2011 OF DUAL ILLUMINATION WITH BOTH THE -DVB S- AND -DVB S2- STANDARDS TO ALLOW AWIPS SITES AND NOAAPORT CUSTOMERS TIME TO FINALIZE THEIR TRANSITION.

Novra S200 Arrives

I received my new Novra S200 and installed it today.  It is working fine with the current NOAAPort signal.  I will see how it performs with the new NOAAPort signal in March.

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.
