I just came across this Wired.com article and it made me wonder if there are any projects out there in the DIY community that have a radio/audio broadcast or recording theme?
Although the article focuses on people who scan radio frequencies my thoughts jumped to a having the actual vehicle broadcast music or some message over a radio frequency (think pirate radio a la Pump Up the Volume except mobile and less powerful). I'm not sure of the distance but I was kind of thinking of a modified iPod FM transmitter that is used to broadcast your iPod music through your car speakers.
I'm also actually interested in knowing if it's technically possible (and financially possible from a DIY'ers budget) to record audio on the ground from the flying/hovering uav? Tons of challenges e.g. size/weight of antenna and microphone, noise from the vehicle itself etc...
Anyway, interesting article that immediately made me think of both 'Pump Up the Volume' and Coppola's 'The Conversion' and if anyone has thoughts or comments regarding the broadcast or recording of audio via UAV systems please comment. It's an angle I hadn't really thought about until I read this article.
PS I can't think of any practical reason to have a flying pirate radio but the ability to do it still seems cool for some reason.
