This is a pain i did hope that program was new not a rehash ,i did see theres stuff on Linux and mac i also have the one and only sstv app for iphone that does 8 sec as well might have to pinch one the app is 6 dollars i think .
As you think the Dos ones more than likely are original system but needs that little opamp circuit for the communication port, now i have tried jvfax 7.1 in windows 7 and it seems to work but i have not tried it with the circuit in anger not of late any way i recall doing this in xp many times.
There is one site I found a few weeks ago that looked promising at first - forget the complexity for the moment, but I have my reservations as to the claims made. I hope that I'm proven wrong...
Yes its a bit of work not really knowing ,you would rather go an easier path with more choice such as Dos programs even if it is a pain these days .
MMM well i think using jvfax is less work try it on your pc worth a shot does not seem to have a problem in windows .
i don't think it would be clean of that robot system.
...but at least we have a.n.other who's also interested.
Yes this is good more that better may be one day it could be a topic on its own
SSTV is just as interesting as NBTV and some ways easier .....for me i learn for one to use in the other .
I have been in contact via e-mail with him, but he's giving nothing away, perhaps as a result of his agreement with 'ATV Quarterly' which is understandable.
Oh ok but he is welcome to join say hello

You'll also note that all is under 'perfect' signal conditions, no noise, fading etc...[/quote]
I like the weather satellite fax system you just lock onto the one AM tone line frequency 2400hz of the system the gray scale white to black is just higher or lower volume of that tone, great system for a PLL,you can lock on to the signal in noise levels we would have no hope of detecting .
And its a mechanical camera with a rotating mirror drum for the line and the movement of the space craft for a never ending frame number of lines,well you would have to follow the signal around the earth and it does end when the space craft falls from the sky end of it s useful life.
Sstv is sort of fax in a way all early image systems should not be forgotten !
