I am thinking of crowd-sourcing my antennae. Find the local ham radio club in each city, and then offer $1000 or something as a prize to whoever gets the best signal through. I know these people all have their own transceivers. So I am trying to think of a way to make a nice cheap transceiver, and a way to modulate a signal onto it from a really simple PC program. It don't need no minimum shift keying or anything like that. Getting the received signal off of there is a little harder. Any ideas as to how I can go from a C program over a USB cable to either a standardized budget radio peripheral and their antenna, or even somehow interface to a USB pin to a a variety of transceivers that are not designed for such an interface?At 15 kilohertz, I could go three cycles on, three cycles off, and get 5 bits per millisecond. If we establish a base price or handle over wired Internet, that gives us a 32-tick range around it for the latest price over radio. So it is not totally crazy to contemplate an open-air audio modulation. It would be pretty crappy. But it might be enough to test the antennae, and then bring in the real equipment after the antenna has been selected.
