Several members of the club have been experimenting with Light/Optical Communication using special types of LED's called Luxeons. 

To find out more about this new and interesting diversion from normal HF, VHF, UHF & SHF communication click on the link below and knock yourself out with all the info, there is also some recordings of the actual QSO's between the two locations, photo's of the light boxes, This site is well worth the time to have look.
Congratulations to all the people involved in the new Victorian Light Communication distance record, 102Klm's from Mount Hooghly to Mount Donna Buang.  Great Effort guys and keep up the great Amateur spirit!!!!!
