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

Windows not visible after screen resolution changes
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
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
WxMap - Speed Increases
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.

Twitter and Facebook Support in Weather Message
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.

WxLocal - Speaking the local weather conditions
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.

Sending Multiple Emails
The email processor will generally work through the queue in short order. If the email group has a large number of email addresses, it does take some time to send each email address to the smtp server. While all of that is taking place the other email tasks are waiting.
I have completed the code to create a pool of threads. This pool could be used to spawn multiple threads that will take a task from the email queue and start sending it to the smtp server. The question for now is whether this will make the overall sending faster. If the smtp server is throttled per connection, having multiple connections could make sending emails faster.
I ran into a situation with a SNPP server that was slow per connection. In this case, using multiple threads could have made that faster.
Now that the code is complete, I will be running some tests to see how this will work. If the smtp server allows for multiple connects from one user, we might be able to deliver emails faster. For users that only have a few groups, this would not have any affect. For users that have bunches of email groups that are activated often, this may make delivery faster.
Note: If the limiting factor is the internet pipe speed, there is nothing that we can do to make it faster.
I will report further as testing starts later this week.

Backlog of files to be processed
I have not seen this problem myself, however, I knew that the ingesting routine in Weather Message Server was ready for a make over. I spend some time over a couple of days to rewrite the queue processing and ingest routines. These changes will help with the backlog of files.
I moved the file processing to an independent thread. I moved the ingest directory read operation to another independent thread. The ingest processing routine will now read all files in the directory at one time and queue them for the processing routine. The processing routine will then process them back-to-back without any internal delay. The previous routine had some delay between each file.
I downloaded and processed the 3 hour EMWIN ftp archive. This archive contains over 2400 files. The server processed them in about 2 seconds. The performance was definately improved.
I have to admit that I have a new 64bit Windows 7 computer with an i7 processor. That cpu contains 4 cores with hyper-threading. The i7 appears in the performance monitor as 8 cpu's.
A word of caution is always in order when creating additional threads. Some think that the more treads you create the faster the processing. That may not be the case for a single core computer. Each thread has to share time on that one cpu. You start to see the benefits of multiple threads when you have mulitple cores.
The changes will definately improve the program's processing speed, regardless of the number of cpu's.

User Defined Product File
The Weather Message Program Update installer asks the user if they want to install a revised Product.dat. If this question is answered Yes, the installer overwrites the user's Product.dat. In most cases that is not a problem. For those users that are manually maintaining their Product.dat, it is a big problem. The user can always restore the Product.dat file from the backup folder. They however will not get the updated product file.
In the next beta, users that want to modify the product.dat file should update ProductUser.dat instead. All additions and changes will be added or overwrite those in Product.dat. This will allow users to easily add and change products without losing the ability to receive an updated Product.dat file.
This capability will allow me to easily define user specific products for the siren controller application. I will not have to worry that the next update will wipe out my settings.
Thanks for the suggestion Todd.

EMWIN Satellite Transmission Threatened
This release seeks to reallocate this frequency spectrum for "broad band" internet. This action would completely destroy EMWIN and LRIT services. Users have until June 28, 2010 to comment on this request. See FCC Release for more information.
I plan on posting a reply and writing to NOAA and my congressmen. Now is the time for action - all EMWIN users, both satellite and internet based, should object to any reallocation.
I will be updating the blog on this as I learn more.

EMWIN Software Demodulator
I had a user attempt to install the EMWIN Software Demodulator on a Windows 7 64 bit system. The NWS installer kept reporting that Data1.cab was corrupted. Right now I don't know why it reported that file as corrupted.
In order to get around this problem, I created a new installer for the EMWIN Software Demodulator. The new installer corrects a number of problems associated with Windows 7 (and I suspect Vista). The new installer does not require the user to unzip the installer to a directory, then run setup.exe. It also defaults the demodulator to the EMWIN-N signal (19200 speed).
For Windows 7 users, with UAC enabled, the EMWIN Control panel would not start or stop the Data Source or Demodulator services. This happend because the control panel applet was not running with elevated privileges. The new installer creates the menu option with the options necessary to launch the control panel with elevated privileges. (WxEmwin should start it properly.)
I went ahead and included the Weather Message Software Demodulator extentions. These extensions allow the EMWIN Software Demodulator to send status message to WxEmwin so that it can display operational information about the EMWIN Software Demodulator.
The NWS EMWIN Software Demodulator is provided free by the National Weather Service. The repackaged installer is available on the Weather Message website.

GOES 12 - drifting to 60 degrees - now transmitting
For those of you that do not have a 19,200 receive system and cannot see the west coast satellite, you should be able to reposition to receive the GOES 12 data stream. The satellite will continue drifting until it arrives at 60 degrees around May 21.
I have not tried to receive the signal yet, but will over the weekend. My dish, due to mounting location, cannot be positioned to the west coast satellite.

Testing the new EMWIN Internet Feed
Each connected client should consume about 19kb of bandwidth. Some clients (ingest programs) can received compressed packets which reduces the bandwidth requirements. Right now with 40 clients connected, the average bandwidth used is around 510kb. That averages out to 13kb per connected client.
I have been submitting routine reports to the EMWIN Team. I hope they find the test successful and begin moving all servers to the new EMWIN feed.

Lightning - Probably time to upgrade to Windows 7
I lost two wireless routers, an on board lan card in the development computer. I don't have any phone service. The ham repeater will talk but not listen. I am sure there are other devices down, but will not know until I start restoring some of the things.
Good news is the internet satellite did not die, EMWIN receiver is good, and NOAAPort is working great. Some people build great equipment and charge a little extra for lightning protection in their equipment. I don't think the parts in the LinkSys with stood the test...
I am now considering a new development computer. Lightning -- yes time to consider upgrading.

Weather Message 3.6 Beta 9
Saturday, February 27, 2010
WxByte/WxIngest/WxEmwin will not decode - Regional and Language Options
I got the user to run WxEmwin with the LOG option and reviewed the results. The program was failing to decode the date in the EMWIN packet header. The date looked ok to me. I got the user to check their Regional and Language Options and discovered they were set to English(Australia). The user was in the southern hemisphere. That setting changes the internal date routines to expect the date in DD/MM/YYYY order. The EMWIN header is in MM/DD/YYYY order.
I got the user to change their Regional and Language Options to English(United States) and WxEmwin started decoding data. Previously, it worked for sometime at the beginning of the month, but failed after the 12th day.
This issue affects all version 3.x releases of Weather Message. It may also affect the version 2 programs - I did not test them for this problem.
I have made changes for the next release that will address this problem. I reviewed all of the programs that validate dates. If they are expecting the date in MM/DD/YYYY order, they will now use the culture settings for the United States to make those validations.
Thanks to Colin for his help in identifying this problem.
Integer Overflow Checks
With integer overflow checks enabled, the internal routines would check to see if an integer overflow occurred for each math operation on an integer. That is simply not necessary in Weather Message. There are lots of loops that use integers in Weather Message. Checking for an overflow in those well behaved loops is not necessary.

Alarm Tab changes for Wind Speed
Severe Thunderstorm - Wind Speed and Hail Size
Only SVR and SVS products issued by Central Region forecast offices will contain the "WIND...HAIL" line. If your forecast office is in the Central Region, you can use this option. For other forecast offices, using this option will cause your alarm to not work.
Wind Speed will range from 60 miles-per-hour to 100 miles per hour. Hail Size will range from .75 inches to 4.00 inches. The alarm option will check for a match or greater speed. (We could add variables for short messages if needed.)
This is a great addition. I hope it will be implemented by all NWS forecast offices in 2011.
Note: For everyone else, if you need this capability, you can use a regular expression to match wind speed embedded in the text.
WxEmwin - Pauses between packets - Revisited
The user that asked the question later sent me an example that I could not explain. In his case, he was using WxEmwin to ingest an intermittent data stream create on a private network using WxRetran. He setup WxRetran so that the stream was not sending data constantly like a regular EMWIN stream. There was no fill file to make the stream constant.
After some research I found a problem in the buffering routines in WxEmwin. When WxEmwin received a version 2 (compressed) packet, it kept that packet in the buffer until the next packet arrived or enough packets arrived to exceed the buffer processing point. Once I saw it happen, I knew exactly what was causing the problem.
This issue would not really be noticed by regular EMWIN users. When I added the option to disable/enable the version 2 (compressed) packet option to the program, the user changed the setting and noticed that the program no longer held packets in the buffer. He just had to convince me that there was a problem.
So --- there was a good post about pauses between packets -- which lead to a real problem that was resolved in the last beta.

Tigertronics - ESP-96
Based on the last information that I received, Tigertronics is evaluating whether to develop a new receiver. At this time, they do not have a receiver in development. In no case will one be available by April.
Users on the West coast will be able to use their existing receivers until the West coast satellite is decommissioned at the end of 2011. The East coast users that can receive the West coast satellite can continue to use their current receive system until the end of 2011.
If you have receive equipment that is not compatible with the EMWIN-N signal, you may want to consider repositioning your dish to see if you can receive the West coast signal.

April 26, 2010 --- GOES East will transition to EMWIN-N
There are currently two GOES-N series satellites, GOES 13 and 14 in orbit and awaiting full time operations. Once they are placed into service the EMWIN-N broadcast will replace the current legacy broadcast. In order to receive and demodulate the EMWIN-N broadcast all users with legacy EMWIN systems will need to obtain EMWIN-N capable systems.
Although subject to change, the current plans are for:
After GOES 13 becomes operational, GOES 12 will be moved to 60 degrees west to help support the Caribbean and South America. We are attempting to have the EMWIN-I 9.6 kbps signal remain on the GOES 12 satellite in order to ease the transition for users.
- GOES 13 to replace GOES 12 (East) on or around April 26, 2010
- GOES 14 to replace GOES 11 (West) in December 2011
The transition could occur earlier due to premature failure of one or both of the current GOES satellites. All users should consider migrating to EMWIN-N capable systems. Please see the vendor page on the EMWIN website. Anyone with an EMWIN-N system can try out the broadcast by using GOES 14 satellite, which is providing a test broadcast.
Why the transition to EMWIN-N:
Changes in the next series of GOES satellites, the GOES-N thru P constellation, have necessitated development of EMWIN-N. Sometime before 2011 the current GOES satellites will be removed from operation and will be replaced by the new series. This will allow for the use of improved technologies, but all current EMWIN users will need to migrate due to frequency, power and modulation changes.
Coming Improvements Include:
- Data rate is doubled to 19.2 Kbps - More data!
- Forward error correction - Greater reliability
- Increased use of compression - More data!
- Enhanced data stream - Including regional Nexrad images
- Dedicated transponder
- No eclipse seasons

WxEmwin - Internet Ingest - Pauses between some packets
At 9600 baud, the current EMWIN data rate, one packet should be received about every second. If the ingest engine is receiving a version 2 packet, the time between the packets could be longer. A compressed packet increases the time between packets.
There are also other forces at work. The TCP/IP subsystem in Windows uses the Nagle algorithm to improve the efficiency of the network by reducing the number of packets sent. See Wikipedia's definition.
Windows may combine shorter packets into one larger packet before it is transmitted. This act increases the efficiency of the network, but does cause small delays in packets. The maximum transmission unit (MTU) for ethernet is 1500 bytes. See Wikipedia. This number could be less depending on the configuration of the network.
A version 1 EMWIN packet contains 1106 bytes. This number is less than a MTU of 1500 bytes. Because of this windows could add additional bytes from the next EMWIN packet to reach the MTU support by the local network. If the MTU is smaller it is possible that it could take multiple TCP/IP packets to transmit one version 1 EMWIN packet.
For version 2 EMWIN packets, this phenomena is more pronounced. Version 2 packets are variable length. This means that windows could possibly combine one or more packets into one larger packet before it is transmitted.
Regardless of whether packets are combined, WxEmwin's Internet ingest code will process the received packets properly. You may simply notice some pauses in the status window.
Note: The next release of WxBBSrvr will disable the Nagle algorithm so that I can evaluate the effect on the received data.

GOES 13 scheduled to replace GOES 12 on April 14, 2010
http://www.ssd.noaa.gov/PS/SATS/SPBULL/MSG0261654.01.txt
This change will have a big impact on EMWIN users. GOES 13 will transition the EMWIN data stream from 9600 baud to 19200 baud. This will affect anyone receiving data from the GOES East satellite.
When the transition occurs, if you do not have equipment capable of receiving the new EMWIN-N signal, you will be required to reposition your dish to the GOES West satellite.
You can watch for update messages on the Satellite Information website: http://www.ssd.noaa.gov/PS/SATS/

EMWIN Port 2211
I am glad to see a recognized port adopted (Thanks Antonio). I guess I just let this information get by me. I will be running some experiments to see what problems users would encounter switching from port 1000 to 2211. I am sure some users have opened their firewall ports for outbound connections to port 1000.
There is presently one ByteBlaster server running on port 2211. I may change my server for testing. Having a couple of servers on port 2211 will make the transistion easier to adopt.
Multicast Address
I knew that EMWIN was assigned the multicast address 224.0.1.143. I never had access to a multicast network, so I did not do anything with this information. I am considering adding support for transmitting and receiving data by multicast.
Server Discovery
I am working on some changes that will allow the client applications to automatically discover a weather message server that is on the local network. This will make installing the clients easier for the end user.
These changes are in the idea stage, but should be relatively easy to implement.
Update: I have completed the changes for this feature. It works well on the local network.

SSL Email Changes - Message Date Problem
I received an update from my TCP/IP vendor that corrects the problem. I will be releasing a new beta this Sunday to address the problem. If you are having the problem, just drop me an email and I'll send you the installer.

Optimization Weekend
I also started changing several of the internal lists to dictionary collections. The dictionary collection can locate items much faster. This would be something like getting the description of a product. The old method was to iterate over the items. The dictionary method is much faster in most cases.
Before changing anything, I wrote programs to compare different approaches. This has taken the better of three full days. However, I am pleased with the results.
I want to do something with the county names list. I am still running tests to see which approach is best.

Weather Message 3.6 Beta 3 Posted
This release also contains a few additional features. See the release notes on the beta site.
Note: Due to the update to the TCP/IP components, you will have to upgrade WxLocal, WxDataSave and WxRetran if you use them on your computer.

Weather Message Website Download Problem
After spending all day today on the problem, I think the problem may be Internet or router related. I have called a couple of people that have Charter Internet and their downloads are working.
If you run into a problem, let me know. I can email you the installer.
Weather Message 3.6 will have all "exe" and "dll" files digitally signed
This will bring the Weather Message programs into compliance with their recommendation. I started signing the installers with the 3.5 release. That did prevent alot of those "unknown publisher" messages. This is an extra expense, but does bring a level of professionalism to the installation experience and program operation.
No Internet Slow Loading Revisited - Signed Executables
Here is what Microsoft has to say about the change.
The common language runtime (CLR) tries to verify the Authenticode signature at load time to create Publisher evidence for the assembly. However, by default, most applications do not need Publisher evidence. Standard CAS policy does not rely on the PublisherMembershipCondition. You should avoid the unnecessary startup cost associated with verifying the publisher signature unless your application executes on a computer with custom CAS policy, or is intending to satisfy demands for PublisherIdentityPermission in a partial-trust environment. (Demands for identity permissions always succeed in a full-trust environment.)For services they go one step further with this note.
We recommend that services use theAfter reading this information published by Microsoft, you would think they would disable this by default. See this KB article for more information KB936707.element to improve startup performance. Using this element can also help avoid delays that can cause a time-out and the cancellation of the service startup.

No Internet access can cause slow program loads
This occurs with programs that are digitally signed. (Microsoft recommends that all programs be digitally signed.) The .Net Framework attempts to verify the digital signature. One of the operations it performs is to see if the digital certificate has been revolked. If the computer cannot access the Internet, a 30 second to 1 minute delay may be encountered.
The Weather Message programs prior to version 3.5 have not been digitally signed. They however use components that are digitally signed. Starting with version 3.6 some of the individual programs will be digitally signed.
If you have a computer that does not have Internet access, I recommend that you disable the check for revolked certificates. This can be done by starting Internet Explorer. Cllick Tools, then Internet Options. Click on the Advanced Tab and scroll down to Security. Uncheck the "Check for publisher's certificate revocation" option. After saving this change reboot the computer.
Note: No one has reported this problem. I just ran across the information today and wanted to post it here as a reminder.

TCP Components Upgrade Completed
I am still testing the changes, but everything appears to be working properly. There were quite a number of changes, but it was completed in record time. It took about 12 hours to make the changes. I had thought it would take longer. The changes between IPWorks version 6 and version 8 were not as drastic as I had thought.
I need to update the documentation with the changes.

TCP/IP Components Upgrade
I am hoping that this upgrade will be relatively easy to implement in the software. I will be working on it during the Christmas holiday. This represents a $1500.00 investment in new software and technology.
This will make the email sub-system fully compatibile with all email servers.

Visual Studio 2008 - Changing the application manifest template
Here is the procedure.
Navigate to
C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplates\VisualBasic\1033
Copy AppManifestInternal.zip to another directory.
Extract the two files in AppManifestInternal.zip to a working directory.
Change app.manifest as desired.
The following is the manifest that I am using. It does not format properly here in the blog.
<?xml version="1.0" encoding="utf-8"?>
<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<supportedOS Id="{e2011457-1546-43c5-a5fe-008deee3d3f0}"/>
</application>
</compatibility>
</asmv1:assembly>
After you complete the changes, zip up the changed file (app.manifest) back into AppManifestInternal.zip. Copy AppManifestInternal.zip back to the original directory.
Now navigate to
C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplatesCache\VisualBasic\1033\AppManifestInternal.zip
In this folder you will find the two files again. This is in the cache directory. Copy the app.manifest that you changed to this directory.
This completes the changes. Now when you add an application manifest to a program using the View UAC Settings button, it will contain the changes for Windows 7.
Windows 7 - Program names that include "setup"
I discovered something interesting. If a program name contains the word "setup", the Windows 7 program compatibility assistant thinks the program is an installer. Weather Message contains the program WxMesgSetup.exe. It thought it was an installer!
As per Microsoft, I had already included an application manifest. This manifest made Vista happy. With that manifest, Vista did not think WxMesgSetup was an installer. The program compatibility assistant was changed in Windows 7. It still thought it was an installer, because it did not write an uninstall registry key.
To my dismay, when I clicked Save in Weather Message Setup, I was greeted with a window that said "This program might not have been installed correctly." I had a prompt to reinstall the program or indicate that it was installed correctly. Well the program was installed correctly.
After some research time, I discovered that Windows 7 wants a special GUID placed in the manifest of each program to indicate that the program is fully compatible with Windows 7.
I updated all of the programs with this special GUID. Now Windows 7 no longer thinks WxMesgSetup.exe is an installer.

VTEC Action Description
Google Voice - formerly Grand Central
It has one feature that I really like - voice mail with transcription. When someone leaves you a voice mail, Google will transcribe that voice mail into text and email you the message. You can go on-line and hear the message or just read the text. (They say that I can use their voice mail instead of my cell phone voice mail. I have not tried this yet, but it would be great.)
It has a number of nice features. If I want to call my friend in New Mexico, I go to the website, enter his number and tell it my phone number. It will call me first and then my friend. No long distance!
They also have a gadget that you can post on a website or blog that will allow others to call you at no charge. I have played with that feature with a couple of my Weather Message customers. I give them a link, they enter their telephone number, Google calls them and then rings my home phone, office phone, business cell and personal cell. If I don't answer Google routes it to voice mail, then sends me a short message on my cell phone.
Now that is what I call number portability. I have one number that follows me everywhere. No more hiding. You just have to get that number.
I am considering using this capability for telephone support for users.
Oh - I forgot to mention that it is free....
Blog Change - Share It Gadget
Weather Message Version 3.6 Installer backs up user files
The Update Installer currently tells the user that it wants to install updated product files. This is a little misleading. There are a number of updated files. For the 3.5 release, this included new FIPS County information and revised Zone County information.
Users will now receive a little more detail letting them know that several files will be updated. It will not include a list of files. It will tell users that if they install the revised files, their original files will be backed up in the directory listed above.
This will allow users to go ahead and install the revised files. After the install is completed, they could go back and restore the files that they have modified.
These files would not normally be modified by users, but in some situations, I have recommended users change these files to accomplish their requirements.

Weather Message posting to Twitter
I corrected the problem in the setup program. I also made additional changes in WxPost.dll so that it would send the user name and password using basic authentication.
I ran some tests this evening and was able to post several short message to my twitter account. I will be releasing this in the first 3.6 beta. I will try to add the setup in the documentation. The service provider screen has to be setup properly for it to work.

Weather Message 3.5 Released
Wednesday, November 25, 2009
Installer File Versions
Starting with version 3.5, right clicking on the installer will display the version number and other helpful information. Notice that the Digital Signatures tab now appears. This indicates that it has been digitally signed.
Security Warning - The publisher could not be verified.
This message appears because the Weather Message installers are not digitally signed. Microsoft calls this technology Authenticode or code signing. Until recently the cost to get a digital certificate was really expensive. In some cases it could cost $499 per year. That is way too expensive for a digital signature.
I discovered a new company that is trying to lower the cost of digital certificates. StartCom/StartSSL began offering free certificates several years ago. They however were not recognized by Microsoft and therefore their root certificates were not installed in Internet Explorer.
Starting with Windows 7, StartCom/StartSSL is now a recognized certificate authority. Their root certificates are now installed by default in Windows 7. They are also available for other operating systems by getting a root certificate update from Microsoft. (These are generally available through windows update.)
You can still get free digital certificates from them, but the ones needed to sign code cost $40.00 for two years. That is a bargin! Because of the price change, I have obtained certificates from http://www.startssl.com/.
Beginning with version 3.5, all of my installers will be properly signed. You will see the following message when running the installer:
It does show my name as the publisher, instead of Weather Message Software. I would have preferred Weather Message Software, however, for $40.00 that is fine.
This should make Windows Vista, Window 7 and Windows 2008 alot happier about installing my software.
I will note that StartCom offers free certificates for S/MIME (email) applications. You can also get free secure certificates for websites. I have not tried one on my webserver, but I will be doing that soon just to see how it works.

emPager Pro Client
This application is now being used by the Tallapoosa County, Alabama, 911 dispatch centers.
Friday, October 30, 2009
My slight detour - emPager Pro
emPager Pro is a simple client/server paging application. It supports TAP, SNPP, SMTP, WCTP, and HTTP (get,post) protocols. You enter service providers, then individual users associated with those providers. Once the individuals are entered, you can easily form groups that contain the individuals.
The interface is very simple. You select one or more groups or individuals, type in a message and click send. There are some quick buttons that allow the users to select "canned" messages. More features will be coming as I develop this application.
Look for this application to be available publicly in the near future.

Labeling Layers
The user wanted to see the road names. Right now Weather Message does not have the options on the layers configuration screen to display the labels or configure their colors. I was able to make a small change that now allows the program to load layer settings from an "ini" file associated with the shape file.
I will post the specifics and update the WxMap help file when the next beta is released.
Text to Speech using AT&T Natural Voices
If you use the Text to Speech option in Weather Message, those voices, priced at $35.00 are a great deal. I wish I had purchased them sooner.

Siren Controller - Live Test Successful
Tom Moore, WX4TM, Lee County EMWIN Coordinator called me this morning to deliver the good news. Frank McLemore, N4TKT, with Communication Electronic Services adjusted the sound levels on the computer interface. Once the deviation was set properly the individual siren controllers responded.
The software can generate DTMF, two-tone, and group call tones using the sound card. This added feature gives users a mix of different signaling capability. All of the signaling methods can be used to activate different devices all at the same time.
The software continues to support external encoders to meet the requirements of different users. They tested the Motron TC1/MX with success. The Motron TC1/MX is an external DTMF encoder.

Map Blinking
It took 17 milliseconds on my 3.4 ghz pentium 4. While it is computing the image, nothing else can happen. That does not seem to bad, but for users with slower machines it could be a problem.

Siren Controller
The first test was a success. The software selected the correct sirens to activate based on the received polygon. It also selected and sent the correct activation codes that control the sound that the sirens produce.
The sirens in Lee County can be activated using DTMF codes. An interface was developed to communicate with the Motron Electronics TC1/MX, http://www.motron.com/ , DTMF controller. The DTMF controller interfaces to a VHF or UHF radio for communication with the sirens. The software can also interface with the Zetron Model 15P, http://www.zetron.com/, multi-format encoder.
I will be going to Lee County later this week to participate in the first on-line (on-the-air) test. Tom Moore, Lee County EMA's EMWIN Coordinator, encouraged me to develop this application.
This first version will be enhanced with additional capability. I will be adding a number of additional features that will make the siren controller a first class application.

Status
This summer has been really busy. Due to lightning damage at my amateur radio (ham radio) repeater site, I have spent alot of time repairing equipment. I am still waiting for equipment (5 weeks now) that has been sent back to the manufacturer for repair.
On a personal note, my grandmother's health has not been good this summer. She is 90 years young. I have had to spend some time at the hospital. She is home now, but she continues to be very fragile.
For the past 4 weeks, I have been in a funeral home every week to visit with my employees that have lost parents or grandparents. I have another one next week. This alone has made the summer a tough one.
On a lighter note, I spent some time today adding some new subject variables. You can now insert the product identifier, issued time in UTC and expiration time in UTC into the email or fax subject line.
I have a bunch of emails printed to review. I will be working those down over the next week. You users have good ideas and I will be working on those as time permits.
Weather Message version 3.5 will be released in the next 2 to 6 weeks. I want to run it a little longer before the public release.

WxScheduler - Variables not replacing
I have made changes in the next beta to address this problem. You should be able to use any text casing.
SSMPT - stunnel - Peer suddenly disconnected
Apparently something changed that caused stunnel to not work properly with this email provider. Version 4.27 works ok with gmail, but fails with the users provider. A quick scan of the stunnel change log did not reveal the problem.
If you have a problem, you might want to download an older version of stunnel.

Email TLS (ssl) Support
I did write a document that described how to setup Weather Message to use Stunnel to provide the SSL capability. Stunnel is a freeware application that creates a secure tunnel for sending emails to a SSL server. This approach does work with Gmail, however, users have to follow the directions carefully.
I got 4 emails last week from users that need the SSL capability. I am investigating this capability again. Microsoft does have a built-in capability to send emails to a server that uses TLS. The only draw back is that the Microsoft method does not provide any debugging information. It either works or fails.
I am looking into adding support for this built-in smtp client. The challenge now is switching between the existing code (no ssl) and the new code. I prefer the existing solution for non-ssl emails because it provides good debugging information.

Web Server Access / Blocking Foreign Countries
I have been adding a range of ip addresses to the router's firewall in order to completely block their access to the server. So far all of the ip addresses have originated in China.
If any one has trouble accessing the webserver, please let me know. I am trying not to block any US ip addresses.

EMWIN 2 - NWS Software Demodulator
After working with the demodulator, I discovered that it did not give the end user any status information. After hours of research I discovered that the demodulator dll did have the ability, but it would be up to the software developer to enable such capability.
I spent this week writing a c++ windows service wrapper around the dll. This new program replaces the default software demodulator service. It now outputs status information on UDP port 18000. This status information can now be displayed an logged in WxEmwin.
I have two users testing the new WxEmwin program, along with the software demodulator. After getting their results, I will post a beta on the website.
