Very interesting.

The FUNcube Dongle Pro+: LF to L band software-defined radio

FUNcube spacecraft now named AO-73 | Welcome to the FUNcube Web Site
Its not very inexpensive....might be good.

Congratulations on the successful launch of the FUNcube-1 CubeSat, launched this morning from Yasny in Russia at 07:10:10.47 UTC November 21st 2013.
Since FUNcube-1 meets all of the requirements for being issued an OSCAR number, including coordination through IARU and requesting such a number; I, under authority vested in me by the President of AMSAT-NA, do hereby name FUNcube-1, ”AMSAT- OSCAR-73″ or “AO-73.”
I, and all at AMSAT-NA wish AMSAT- OSCAR-73 great success in fulfilling all of its mission objectives and we welcome it to the long list of Amateur Radio satellites.
73,
William (Bill) Tynan, W3XO
OSCAR Number Administrator

WxtoImg
WXtoImg: software to decode APT and WEFAX signals from weather satellites
The world's best weather satellite (WXsat) signal to image decoder.
Simply connect a 137-138MHz FM communications receiver, scanner, or weather satellite receiver to your soundcard and get stunning colour images directly from weather satellites. The only other item you'll need is an antenna for receiving the circularly polarised signals. -Not Open Software!

The MX-137 Weather Satellite Station - Wettersatelliten NOAA Receiver and Antenna, WRAASE electronic GmbH - Hardware - MX-137 is my recommendation for use afloat ( I have a QFH at home... no noticeable diff in rx quality).
Wraase also sell dedicated receivers.

Agreed, have the same setup. Best bang for the buck.

As for overlaying, I need a couple of weeks to test this and I will, it should be possible now to save the WxtoImg processed image as a jpg or tif or whatever and then import and calibrate it in the weather fax plug in by reading the lat/lon of corners on the wxtoimg screen.

A feature request for WxtoImg would be save the file in some kind of geo referenced image that the weatherfax pi understands I guess.

Then with a GRIB overlay on top of the sat image you have a good possibility to check the accuracy of the grib against the actual conditions.

Hmmm can't get this plugin to work anymore. Is it ok with west and south lat/ons.

I am trying with the Brazilian synoptic charts for the SW Atlantic. available here Centro de Hidrografia da Marinha - Servio Meteorolgico Marinho

One time the chart showed up but was displaced south by about 40 degrees.. then OCPN crashed.. usually I get no chart display or OCPN crashes.. reports sent each time.

I previously got a display with charts from Chile.. but this is the most useful chart on this side

The pluggin has illegal external references (look in tracker). See this and before.

Will try to push changes once get I get github setup right. The diff is in Tracker, apply those and compile. If you don't compile you will have to wait.

Tried to compile weather_fax_pi again.

git clone git://github.com/seandepagnier/weatherfax_pi.git

Followed Mike [Rasbats] directions to change the files, found in this post
http://www.cruisersforum.com/forums/...ml#post1364794

===

Following changes had to be made in wximgkap.cpp:

Add a function below 'typedef union' bit at the top of the file:

unsigned int log2( unsigned int x )
{
  unsigned int ans = 0 ;
  while( x>>=1 ) ans++;
  return ans ;
}

To avoid ambiguous call for 'sqrt'
Change    return sqrt(r); to read    return sqrt(float (r));
Change sqrt(3*cote*cote); to read sqrt(float(3*cote*cote));
Change sqrt(3*3*3) ; to read sqrt(float (3*3*3)) ;
Change sqrt(3*15*15) ; to read sqrt(float (3*15*15)) ;
Change sqrt(3*63*63) ; to read sqrt(float (3*63*63)) ;
And there may be some other sqrt to amend in the same way.

And the ambiguous call for 'ceil':
Change bits_out = ceil(log2( num_colors)); to read
bits_out = ceil(float (log2( num_colors)));

In InternetRetrievalDialog.cpp and SchedulesDialog.cpp

Add #include <wx/wx.h>

Add the 4 tinyxml files from the main branch to the weatherfax src folder and add to the project.

I did not make this change in wximgkap.cpp:

Comment out this bit 
/* color type and mask */

typedef struct
{
    uint8_t rgbRed, rgbGreen, rgbBlue, rgbReserved;
} RGBQUAD;

It's defined elsewhere.

Output:

Then when this change was made in wximgkap.cpp:

Comment out this bit 
/* color type and mask */

typedef struct
{
    uint8_t rgbRed, rgbGreen, rgbBlue, rgbReserved;
} RGBQUAD;

and ran cmake .. and cmake --build .

I ended up with 49 errors!!!

Sean is sailing north towards Phillipines, when he has internet service he'll post, but for now we hope he is sailing in good weather, and we are on our own insofar as getting this plugin running. I've taken this as far as I am able with my skill set, so if someone has some suggestions or guidance, that would be very welcome.

OpenCPN 3.3.1117 from https://github.com/OpenCPN/OpenCPN
weatherfax_pi from https://github.com/seandepagnier/weatherfax_pi

Using VSC++ 2010, Win 7, OpenCPN 3.3.1117

In WeatherFaxImage.cpp:
Changed ISNAN to read _ISNAN

Or you can use a define like this at the head of the file (like PCM.cpp)
#ifdef __MSVC__
#define isnan _isnan
#endif

Following changes had to be made in wximgkap.cpp:

To avoid the log2 problem I went back to basics:
Change
bits_out = ceil(log2( num_colors)); to read ...
bits_out = ceil(log(float (num_colors))/log(float (2)));

To avoid ambiguous call for 'sqrt'
Change return sqrt(r); to read return sqrt(float (r));
Change sqrt(3*cote*cote); to read sqrt(float(3*cote*cote));
Change sqrt(3*3*3) ; to read sqrt(float (3*3*3)) ;
Change sqrt(3*15*15) ; to read sqrt(float (3*15*15)) ;
Change sqrt(3*63*63) ; to read sqrt(float (3*63*63)) ;
And there may be some other sqrt to amend in the same way.

Commented out this bit
/* color type and mask */

typedef struct
{
uint8_t rgbRed, rgbGreen, rgbBlue, rgbReserved;
} RGBQUAD;

It's defined elsewhere.

In InternetRetrievalDialog.cpp and SchedulesDialog.cpp

Add #include <wx/wx.h>

Add the 4 tinyxml files from the main branch to the weatherfax src folder and add to the project.

This compiled but with a lot of warnings. Seems to work.

Tested with the Chilean fax from Navy Hydrography Center - Marine Meteorological Service This looks ok?

The compiled dll is attached. Remove '.pdf' in the normal way. Please test.

Dear Mike,

I really appreciate your help. I am trying to keep up with your help. The last two or three days, off and on, I have been working on weatherfax and trying to learn git and github.

I have tried the changes you've suggested four times and committed it to my fork of Sean's weatherfax_pi, so you can confirm what I have done.


I have written the sequence and results below, for the last time that I did it.
Unfortunately I have not been able to get a weatherfax_pi.dll compiled yet, results in lots of errors and no warnings.

Thanks again! You are awesome. Rick. (I am going to follow all your work on Weather_routing next.)

Thanks for that update Mike, great work.

I too tested it with the "Brazilian" fax

It works, but I discovered a big limitation in it's use when working with GRIBS. Please see attached screen shots.

Normally you will only download a GRIB file for your immediate surrounding when at sea with only HF or low bandwidth satellite.. The problem is that as you zoom in the fax overlay disappears. I have a very large GRIB file in the example and even zooming into that level the FAX disappears.

Cheers
Chris

P.S. What's this about weather routing?

[rgleason]

Thanks Littlechay, I was going to try the dll this morning.
Mike, do you have any idea what I am missing in the commit, so that it will compile for me?

Rick,

The following are needed:

Change CMakeLists.txt in plugins/weatherfax_pi directory to add src/tinyxml.h src/tinyxml.cpp src/tinyxmlerror.cpp src/tinyxmlparser.cpp

In InternetRetrievalDialog.cpp and SchedulesDialog.cpp

Put #include <wx/wx.h> before any other includes!!! If anyone is compiling for Mac OSX this might also solve their problem.

If you don't edit CMakeLists.txt:

Add the 4 tinyxml files from the main branch to the weatherfax src folder and add to the project.

Google helped me find the include problem.

Please test.

Mike

Littlechay,

For the disappearing fax image:

With NON-OpenGL rendering there is a parameter set in the function:

void WeatherFaxImage::RenderImage(wxDC &dc, PlugIn_ViewPort *vp)

/* dont go too huge */
if(iw > 4096 || ih > 4096)
return;

I changed this to: iw > 12000 || ih > 12000 and I can zoom in much closer before the fax disappears. Not sure if there are any side effects. There is still a final limit to the zoom-in you can use.

If you want to try this fix I have attached the dll. Perhaps rename your old dll as a backup!!!

Suggest using flyspray to request this feature from the developer, Sean D'Epagnier, if you see a need.

Say hello to Port Stanley. Some good times spent in those parts.

Thanks Mike, that works fine. See attached which shows the closest limit that I could zoom before the fax disappeared. You can really see how the GRIB and the human forecast don't match

What were you doing in these parts? Sailing, who with/what on? If so we probably met.

Mike, these changes did the trick. The plugin is working now in Windows! Thank you. Will commit and send to Sean with your changes.

Sean has mapped out some very ambitious improvements here! This is going to become a great tool for anyone able to get the radio signals for WeatherFax.
