A few of you guys> asked for updates then also. Brian and I were> considering attempting NLOS communications, but> obtaining that first with LOS QSOs.> I built very simple equipment consisting of K3PGP> type electronics (front end and modulation) but did> modify the circuits some, for a science fair hosted at> my school. We went to regional won Grand Prize and are> now on our way to the International Science and> Engineering Fair. I don't want to describe the project> because I'm not sure what rules there are against it> so its just easer not to.> In any case our tests spanned a short distance of> a half kilometer but it was perfect for the tests.> Janet was working with me on the project while Brian> decided to work on a different project. The aiming> devices that Janet and I made were not suited for such> a distance so took a while to get aligned.> I've uploaded a video to youtube that highlights> some of the project. The URL is> http://www.youtube.com/watch?v=qQ7m5GgcghA .> Brian and I are planning to make equipment for DX> laser communications instead using KA7OEI type> receivers and slightly higher power laser diodes,> don’t worry we will be careful.> Thanks all for your suggestions and help!> -Jimmy Carter - KG4SGP> > PS: Janet is getting her license in part because of> this project.
