Title: Transmitting WEFAX images with FLDIGI
Post by: Strange Beacons on January 18, 2019, 0130 UTC
Does anyone here have any experience using FLDIGI to transmit images using WEFAX mode?

I have been attempting to transmit images, but keep running into the problem of the program timing out after 5 minutes of transmitting (a dialog box opens that says, "TX timeout expired! Are you awake"). The FLDIGI guide suggests going into the configuration settings and changing the browser settings for "Inactivity timeout" via the scrolling menu that is there. I have done this, using every setting possible and the program still times out after 5 minutes.

Not having any luck with that, I then tried making the images smaller, thinking that lower resolution and small sized might help. Still no luck.

I've reached the end of my tweaking and tinkering with this and could really use some help from anyone who has successfully transmitted WEFAX images with this program. If you could help me with any FLDIGI settings that I need to check, or with changing the images to make them more friendly to the program, I'd really appreciate it.

Thanks.

Perhaps the app's coded with a line in the exe that shuts off tx after 5 mins regardless of the option. In that case I'd be looking at dm780 or easypal or some other sstv app.

Yes, that is what I suspect, too (a line of code to shut off transmission, likely done to protect the radio from overheating).

I'm already using a couple of good SSTV apps. I was essentially just wanting to experiment with sending via WEFAX, as I kind of like its old school black and white image format.
