I do not understand: Why is an "automatic slant" possible with the 
analog SSTV images (MMSSTV) - in digital mode not?
Why are there in the digital images without internal reference line for 
an automatic orientation and wherefore the MFSK Alghorithmus has only so 
marginally digital benefit?
In broadcasting of the radio amateurs I see never a MFSK image - but 
already hundreds EASYPAL images ......
