Diy radio transmitter for medium range, 1 mile
Im a scout leader and for some of our events we need to be able to do announcements over the radio but as most of our sites don't have loud speakers set up all the time we have to rent them, and the people to set them up. Even with a discount this can go into the thousands and that goes back to the kids costs and well i hate that.
Anyway after playing around with my partners short distance radio transmitter that plugs into her iPhone i wondered if its possible to modify, or build a transmitter like this for longer range.
Anyone got any links?
It needs to be fairly clear, doing music and announcements that people can hear over about one km to one mile.
