INTRODUCTION

The Ramsey FM10A is a true STEREO FM broadcast transmitter, which any person may build and use in accordance with the rules of your nation’s telecommunications authority. For U.S. residents, that authority is the Federal Communications Commission (FCC). The FM10A's low-power broadcasting capability and other practical uses can be fun and interesting for people of all ages, but the FM10A is definitely not a toy. We will refer to the FCC regulations frequently in this manual and provide you with some information necessary to enjoy the FM10A's capabilities in accordance with the law.

Typical uses for the FM10A include the following:

•Extension of home stereo system - without wires.

•Listening aid for auditoriums, churches.

•Student-operated school radio station.

•College dorm favorite music broadcast service.

•Short-range, two-channel experiments and demonstrations.

We think you will be very pleased with the transmitting range, audio quality, frequency stability and stereo channel separation of this build-it-yourself FM stereo transmitter. If you follow our assembly directions carefully and use your FM10A in accordance with applicable FCC rules, a whole new world of sharing music, news and views with friends and neighbors awaits you.

Since the sharing of music and information is vital to the culture of our late- 20th-century global community, we realized that our FM10A low-power FM Stereo Transmitter kit was certain to attract worldwide interest among hobbyists, students and "pioneers." While the use of the FM10A may need to be limited to "wireless stereo extensions" in some USA households (to comply with FCC Rules, Part 15), we have seen it serve very well as a serious, though simple, broadcast station for remote villages throughout the world where low cost AM-FM receivers are available to people of all economic levels. After you're done building your kit, sitting back and listening to your handiwork, consider this: many other FM10A's just like yours are faithfully relaying news and information to listeners in remote parts around the world. The FM10A is most definitely not a toy!
