DEFINITELY ON ANOTHER (normally voice) frequency.  SSTV transmissions take 
anywhere from 36 seconds to 2 minutes or more -- defintely NOT something you 
want on 144.39!

A laptop computer running any standard soundcard SSTV software such as mmSSTV, 
ChromaPix, MixW, etc with it's sound system input and output connected to the 
6-pin mini-DIN jack,  or the mike and speaker jacks.

An ideal platform for this is an inexpensive light-weight "Netbook" PC.   These 
mini-laptop machines that are actual standard Windows PCs that run normal 
Windows software,  are now out-of-fashion in the mass retail market due to the 
overwhelming impact of the iPad and other tablets.

Netbooks are now often available for under $225 from online sources like 
newegg.com or tigerdiect.com.       These machines which will run for 4-6 hours 
on their internal batteries (or that consume less than 10 watts from an 
external source) always include a webcam which can be used for ORIGINATING live 
SSTV images, as well as receiving pics from others.
