EMWIN 2 - NWS Software Demodulator

I have been distracted for the past week. I borrowed one of the new Werner EMWIN 2 satellite receive systems. This system uses a software based receiver to decode the 19.2 EMWIN data stream.

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.

WxMap - Upload Dynamic Map Legend

I am making changes to WxMap to support creating a dynamic map legend. This map legend would be uploaded to a website at the same time as the map image.


I have asked some users that have inquired about this feature to send me comments.
