I have a better idea. Make the plugin able to open kap files. Then add an option to export all the files at exit and open them all when the plugin starts up.

Various scripts complementing OpenCPN

Some of Pavel's work might be applicable to making the plugin work with KAP in and out, I think. You also might consider BSB files.

PS: I think somewhere in Tracker someone suggested making Weatherfax a Kap Editor, but I think Sean believes it needs more mapping capability.

Re: WeatherFax...

Perhaps we should be taking the weatherfax sources above and creating the XML records to be included with the plugin XML source files. It will make it easier for Sean, and his time is better spent programming! Any volunteers?

Interesting effort at online Kap generation, but written in Java.
Online creation of BSB/KAP files from Google Maps

Re: WeatherFax...

Please VOTE for this Tracker Item #1449.
It will make Weatherfax simpler and much much better and even more useful.

FS#1449 : Add Kap read /write and save all current overlaid images to KAP to preserve lat long data.

Re: WeatherFax...

Instructions that should be included with the README.doc
==============================================
In order to compile with MSVC++ the new Weatherfax_pi that supports portaudio in Windows you still need to do the following.

At Run "cmd", then git pull
cd C:\..\o-plugin\weatherfax_pi
git pull

Then
Download this file
wf_depends.7z from
Download opencpnplugins from SourceForge.net

Then unpack wf_depends.7z files (the full complement) into this directory:
wxfax_pi/buildwin directory
You should have curllib.dll, curllib.lib, libcurl.dll, libeay32.dll, libsasl.dll, openldap.dll, portaudio_x86.dll, portaudio_x86.dll, portaudio_x86.lib, PVW32Con.exe, ssleay32.dll in the buildwin directory.

Then comment out and save:
C:\..\o-plugin\weatherfax_pi\src\libaudiofile\
CAP.cpp on line 31
/* #include <inttypes.h> */

Then at cmd
cd build
cmake ..
cmake --build .
cmake --build . --config release (see comments below re 12 errors)
cpack
..and it compiles successfully. No errors. No warnings. and makes the install file.


Comments - 12 errors
-------------------------------------
cmake --build . --config release
had 12 Errors the first time executed (see below), the second time it had 0 warn, 0 errors. - Why?

Re: WeatherFax...

See for update to the plugin:
Sean Depagnier's Plugins - Page 11 - Cruisers & Sailing Forums

Please test and advise. Saves KAP, and Sean is going to make it read KAP later to simplify use with regard to georeference information and the need to reuse the Wizard...

Re: WeatherFax...

Please note that Sean and Pavel got the plugin so that all programs and files are completely contained in the install exe so there is no need to download additional "helper" files. This improvement has been a big help to users!

Find the most current file here: Opencpn Beta File Thingis rguser rgpass

Re: WeatherFax...

Review of less expensive Radios
http://swling.com/blog/2014/07/the-m...-icf-sw7600gr/

Sean uses Tecsun pl 660. - Useful to have a plug in for soundcard however, so consiider Tecsun pl 880, but some tests show it is not as sensitive for weaker stations. Sean, what do you think about this factor? Is the sensitivity for weaker stations important if you use a wire antenna like a shroud?

Re: WeatherFax...

Sean,

Have tried using the rtlsdr dongle with SDRsharp to identify and select a frequency that has a weatherfax or something useful, streaming through SDRsharp

Then I have turned up the volume and started Opencpn 3.3.2118 and opened Weatherfax and selected "Retrieve" "Audio Capture" and the sound is transcribed into Weatherfax.

My question is this. Is there some wiring techniquue that is needed with this setup to get a better connection? Or does the plugin have that already wired?


Also "If you need to simply share your In/Out wave ports among several applications under Windows 2000 and earlier Windows versions, take a look to the Wave Clone software."

I could put a sound wire with proper plugs between "Microphone In to sound card" and some output source, but what (to get the rtlsdr signal into the microphone). Where would I plug the other end to do that?

Also see Virtual Audio Cable Virtual Audio Cable Home Page
and Free Virtual Audio Cable Alternative - rtl-sdr.com

Would these work be of any help? Also is there a version that works for Linux too.

Also
Tutorial: How to Enable Stereo Mix in Windows 7
Tutorial: How to Enable Stereo Mix in Windows 7 - rtl-sdr.com

Now stereo mix is enabled and ready to use! Any audio coming through your speakers will also be piped to stereo mix which can be selected as an audio source in most programs that require one. If stereo mix is not showing up in the recording properties window, try updating your sound card drivers.

Re: WeatherFax...

Weatherfax-pi (as an example)
================================================
Source ---------------------------- Soundcard --------------- HF Radio or SSB
File Open Image file ----------Not applicable ------------Not applicable
Retrieve Internet Image ------Not applicable ------------Not applicable
File Open Audio file -----------Decodes sound ----------Not applicable
Retrieve Audio Capture-------Decodes sound*----------Receives signal **

**You need to connect the Radio signal "output" to the Soundcard "Input" or "Microphone in" with a physical cable.
