INTRODUCTION TO THE FR1 FM RADIO RECEIVER

Why you may ask does Ramsey sell a 'plain old FM radio' receiver? No better

person to ask than yourself! The FR1; teaches radio theory, allows you to

tune outside of the standard broadcast band (great for bugs, FM mikes and

other goodies!), has easy hook up for SCA adapters, small size and is just

plain fun.

Your receiver kit is designed to receive wideband FM transmissions typical of

standard FM broadcast stations, wireless mikes, telephone transmitters and

the like. It was not designed for Narrow Band FM transmissions (NBFM) as

you would find on police and fire transmitters, Ramsey offers a complete line

of receivers for those services.

The FR1 demonstrates a whole lot of basic radio theory in one compact,

simple circuit! Separate circuits are 'on-board' for all basic parts of a receiver,

making it easy to visualize every function. The latest in IC circuitry is used

which allows high performance without requiring exotic construction skills.

We think you'll agree that this little radio offers a lot of bang-for- the-buck, so

let's get building!
