3.0 INTRODUCTION

This section explains the technical theory of operation for the RCI-6900F HP / RCI-6900F TB mobile
transceiver.

3.1 PLL CIRCUIT

The Phase Lock Loop (PLL) circuit is responsible for developing the receiver's first local oscillator
signal and the transmitter's exciter signal. The PLL circuit consists primarily of IC2, IC3, IC4, IC5
