FM25B • 4

INTRODUCTION

The Ramsey FM25B is a true SYNTHESIZED STEREO FM broadcast transmit-

ter, 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 FM25B’s low-power broad-

casting capability and other practical uses can be fun and interesting for people

of all ages, but the FM25B is not a toy. We will refer to the FCC regulations fre-

quently in this manual and provide you with some information necessary to en-

joy the FM25B's capabilities in accordance with the law.

Typical uses for the FM25B 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, fre-

quency stability and stereo channel separation of this build-it-yourself synthe-

sized FM stereo transmitter. If you follow our assembly directions carefully and

use your FM25B 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 21st cen-

tury global community, we realized that our FM25B low-power Synthesized FM

Stereo Transmitter Kit was certain to attract worldwide interest among hobby-

ists, students and "pioneers." While the use of the FM25B may need to be lim-

ited 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 sim-

ple, 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 FM25B's just like yours are faithfully relaying news and infor-

mation to listeners in remote areas around the world. The FM25B is most defi-

nitely not a toy!
