It would be better to do MFSK16 (+MFSK SSTV) only.

Leigh,
Have you looked at Digital SSTV based on HamDRM? I've just compiled the
HamDRM DLL and am hoping to have this integrated in DM780 in February
sometime.

Hello Howard,
SNIP
I don't have a problem with various kinds of UI, but I do know some
people care intensely.
One of the things I hope to accomplish with the znudigi experiment is a
separation of modem from UI. I amworking with several different UI
designs for znudigi clients, and hoping that others will too.
Leigh,
I have not been following this SSTV discussion very closely as I got the
impression that it was analog SSTV when MMSSTV was mentioned as a
program. Or is this actually digital SSTV? Can you give us a capsule
account?
Do you have any knowledge of any tests that have been done between

Yes, it would be ideal.

Right click on a mode button yuou want to redefine, and a long list of
modes appear. The narrow modes is in the lower end.

Patrick, I just assumed that a digital SSTV mode in 500Hz that could send a
decent size picture in a reasonable amount of time was impossible. Certainly
if it is possible then it would make more sense
a very powerful compression scheme, it's perhaps possible.
The compression used is .jpg or .jp2 (jpeg-2000)
For reasonybly sized pictures 10kb is minimum, 20kb is average size.
The quality does deteriorate rapidly below 20kb/picture.

I have quiet enjoyed the few MFSK pix I have sent, narrowband. The
chatter is all via MFSK, and the bandwidth is narrow, of course. Fldigi
implements it so DRM780 might as well.

The problem with MFSK16 SSTV is that it is tied to MFSK16 and you can't

The MFSK picture mode isn't tied to MFSK in any logical way, only in the
programs. It doesn't use MFSK modulation for the picture, for example.
