Abstract

This paper primarily focuses on the subject of designing, building, and testing a low power, low data rate transmitter capable of ionospheric communications. The signals transmitted by the quarter watt transmitter built in this project were able to be received up to two miles away from the transmitter. With an operating current of about 11mA, a typical 12V power source of AA batteries would allow for continuous transmission for over 227 hours.
