Hello Patrick, hope all is well; Am confused as in your MFSK16 help file it states "IMPORTANT: the picture format is not fixed as in classical SSTV but can be anything. The maximum dimensions of the transmitted picture are 1600x1200. Multipsk proposes to use the standard "320x256" to take advantage of the SSTV facilities and the stored SSTV pictures".
Am sure I am missing something here...

It's a Runlength algorithm which is applied line by line. The transform might be in two dimensions as in JPG to be more efficient, but this line transform permits to get the picture at any time (no block). > > PSE: in Packet, don't use "Immediate stop of the picture transmission".
