Re: suitsat SSTV software



Guys,

IF you use a VOX recorder on your computer, that is better.
But better yet, Use MMSSTV to decode the SSTV LIVE, (auto save files)
and the VOX recorder to record the audio messages from Suitsat.
Then you also have a backup of the SSTV stored digitally!
No worries about speed!
For a FREE Vox recorder that works great, go to
http://xoomer.virgilio.it/aporcino/VoxRecorder/

It can't get much easier than this.

73, Scott
P.S. I have been doing this same thing for a couple of years now.
Works just fine!
