WeatherFax ...

[kubek]

Hi,

I have tried to use capture mode Ctrl-a and plugin immediate crashes OpenCPN.
I have reinstalled plugin few times, but it doesn't help. It writes to the log "WeatherFax.cpp:200 Weather Fax : Failed to load coordinate sets"

End of opencpn.log:

Any idea how to fix it?

The error means that the plugin can't find the file : "CoordinateSets.xml"


Had a look at the source code, and it seems that you have to download/update some utility files.
Menu : "Retrieve" / "Update Data Sources" " (CTRL+H) and see if it works.
This should download the "CoordinateSets.xml" file (and a few other, if I understand correctly).


Please, report if it saves your problem.


A default files set is not provided by the installer ???

PS : I use the latest plugin version, 1.9.60.0

Default ser is ibstalled. Perhaps was corrupted or missing on user machine.
Yes download a new update .

I have OpenCPN 5.8.4-0, weatherfax 1.9.70.0.

Steps already done:
1. Reinstall weatherFax,
2. Retrive -> Update Data Sources
3. Try to Capture - I see now window but not completed (see screenshots)

Best regards,

So far, so good...


"Failing to Configure Capture" :


Open the plugin's "File -> Configure" menu and play with the "Device Index", and save. Default is 0 and should work unless you have several interfaces.


Maybe you may have a missing/wrong/corrupted preset file ?

Hi,

Thanks for advise, but when I tried to change it to 0 or other number, it is always set back to -10001 (see picture)

This is the heart of your problem.

But since I'm using Linux, I can't try to reproduce

What does your log file says ?

1) Config dialog test on Linux :

The parameters on the dialog are ALWAYS SAVED when you CLOSE the config dialog (Samplerate, Device Index, ...).

Apparently, the saved parameters are correctly used when you launch the plugin.

BUT the settings dialog is not preset with the saved parameters when it is reopened (only the default values).
(Apparently, the required source code is missing).
Consequence, if you reopen the dialog and close it, the default parameters are saved and erase the previous values.

==> To use the previously set parameters, don't reopen the setting dialog !!! (as the defaukt parameters would erase the prevous one when you close the window).

Probably something to improve here...

Now, the -10001 value?? maybe the windows version of PortAudio has a problem ? OR windows doesn't use the PortAudio library ???

2) Basic tests on Windows

First, check the sample rates supported by your interface, and set the default inputs and outputs to the interface you intend to use for fax decoding.

If 8000 is not supported, use 16000 or 48000.

One possibility: go to your audio settings, and check that you have deactivated "exclusive access" to the audio interface (I don't remember the exact details).

3) Suggestions :

Open the settings dialog.
Set the samplerate at 48000 (always supported) and the Device index to 0 (or -1, apparently this means "default device").
close the plugin.
Relaunch the plugin.
DON'T open the settings dialog.
Try a capture.
If it doesn't work, post the log file.

Sorry, I can't help much beyond that.

In the 3) point ("Suggestions"), an instruction is missing.


Add "Close the Preferences dialog using the OK button" before "Close the plugin".


Reason : you have to click the OK button to save the new settings and dismiss the dialog.

Dear PMX would you mind becoming an editor, I think it would be more efficient. It is not hard to edit Dokuwiki there are two different editors pick the one you like.

If so, please send me a Private Message with your email and the username you'd like. I will send you and email with the PW.
I am pretty busy right now and won't be able to get to this.
Thanks.

PS on second thought it is not in Dokuwiki anymore, it is using AsciiDoc/antora and requires a free opensource github account. Do you have one of those?

Thanks for help!

Now value is set to 0 and Capture works again.

In this manual what would you add for instructions?

https://opencpn-manuals.github.io/ma..._weather_faxes


I am also considering how to integrate this long post from PMX into the manual, this appears to be mostly about WebSDR, not Weatherfax

https://www.cruisersforum.com/forums...ml#post3816899


Your specific suggestions would be appreciated.

[rgleason]

I think we need to make this a Step by Step Use example which is towards the bottom of the Manual.


Also there are a number of screenshots that are missing from the original manual which is still here.
https://opencpn.org/wiki/dokuwiki/do...her:weatherfax


We should probably move these images (optimized) into the new manual too.

Dave has added ASCAT A&B data retrieval to Weatherfax. Now we need a knowledgable user to create the coordinatedata.xml for this data to provide a seamless overlay.

Hi Rick et al,



has anybody realized, thet the satellite images do not work any longer in Weatherfax? The URL seems to be invalid. Looking at the "Aviationweather" Page, and playing around a bit with looking at the "regional" satellite images, the requests get blocked


Does anybody know about this, or is there a new source?


Thanks for any help and best regards,


Uwe
