I need to make a simple radio frequency transmitter with the following
characteristics: range of a few miles, transmit on a single frequency, 
energy derived from a button cell, CHEAP.

Any ideas on how I can build something like that?  Would a simple crystal
oscillator do?  

Thanks for your help.  Please email me at gn1@umail.umd.edu
