One of my favourite things in amateur radio is to work modes that are quite niche. This was especially the case after I had made my custom audio interface PCB for use with my 2M and HF rigs. I had lots of fun sending all sorts of beeps and boops over it. This came during a period when there was lots of experimentation in OARC with lots of different modes that people had never used before, as well as coinciding with the appearance at the time of the shiny new #rx-captures channel - meant for audio clips and data captures (such as RTTY output or weather satellite images).

A popular reception target for those new to amateur radio and HF data in general are the various weather fax transmissions that are sent from various locations around the world. Traditionally something like FLDigi is used to receive these images. However, one thing people may not realise is that WEFAX (in a couple of specific submodes) aren't just receive-only in the software. Like all modes in FLDigi they can be *transmitted* also. However, it isn't QUITE as easy to do as you'd think. Therefore, this guide is meant to give some brief guidance on topics such as image formats and resolution in order to help steer people towards experimentation with this mode from an amateur radio context.
