 ===== Image Preparation =====
-If you've looked into WEFAX reception before you may know that there are various different formats. Usually this relates to lines per minute. As you'd expect a lower line speed results in a potentially higher quality image, more resilient to noise. FLDigi allows you to select from a few different speeds, but 120 LPM will be absolutely fine and matches most (if not all) of the actual weather broadcast stations that you will hear on the bands. Regardless of line speed chosen it seems that the resulting image is always 1809 pixels wide, so it is important to make sure that your image is this wide otherwise FLDigi will do fill in the rest with white space (which you may be ok with!). The height of the image is up to you. Longer images take longer to send and will put more stress on your rig. The exercise of choosing a power output for sending an image is left to the reader - the resilience of your finals being the limiting factor.

 Of course, there's no real restriction on WHAT you send. I usually make some templates in something that people often make fun of, but which is actually a pretty decent package for simple graphic design: PowerPoint. No, really. You can set up templates with text boxes that you can easily change for things like a callsign, RST, and other notes that you want to send. These slides can be exported out, but they will end up being a 16:9 ratio, most probably 1280 by 720 or similar (TODO: See if you can set up a custom slide size for this!).

 Assuming you have CAT control all sorted this is pretty easy. Load FLDigi and select "Weather Fax Image TX" from the View menu. When the new window appears check your LPM is how you want it and then click load and select your image using the file picker. You'll see your image in the window, along with any whitespace to the right if you didn't make it 1809 wide.
+Then hit TX B/W or Color as appropriate to send your image. I have never tried colour, it always seems greyed out.
