Hey,
I’m trying to set up a transmitter that simply broadcasts voice (AM
quality is fine) over a range of a few miles. It would be implemented
in developing world situations, such as rural India or Africa, and
therefore must be constructed with very cheap hardware. We currently
have selected a suitable computer to deal with the software
necessities (saving and queueing audio files to be transmitted), but
what other hardware is necessary for the transmission? I am new to
gnu-radio, and can probably convince the sponsor to pay for a USRP for
research purposes, but of course this definitely would not be able to
be used in the actual implementation.
