SSTV ON A BEAM OF LIGHT
-----------------------
A 13 mile path from Mt Wellington to a hill near Sorrel in Tasmania has been used for 
what is believed to be the first slow scan television transmission via modulated light. 
Good old fashioned analogue slow scan pictures were transferred to establish a two 
contact. Among those involved on the 17 of October activity were Chris Long VK3AML, 
Justin Giles-Clark VK7TW, Rex Moncur VK7MO, Mike Roth VK7MJ and several others.
The optical contact on 474 THz enabling the SSTV, will certainly echo around the world 
and spark interest in this possibility among others who engage in modulated light 
experiments. There were a number of objectives set for those involved, including voice 
contact with about seven people achieving a QSO. The outcome of a "JT65" digital mode 
is still to be determined with signals captured using wave files. Among those involved 
in the latest experiments were Chris Long VK3AML and Mike Roth VK7MJ. The pair have 
experimented with modulated light over the past 35 years. In February 2005 they claimed 
a world distance record of 104 miles, spanning from the south to the north-east of 
Tasmania.
