RCI-2950 Controls and Connections

INTRODUCTION
This section explains the basic operating procedures for the RCI-2950/2970 amateur 10 meter mobile transceiver.
CONTROL & CONNECTIONS

1. FREQUENCY SELECTOR:

This control is used to select a desired transmit and receive frequency. It enables you to make a continuous tuning over the entire
range of the transceiver.

2. RF POWER CONTROL:

This control enables you to adjust RF power continuously over the range of 1 watt through 25 watts
(RCI-2970: 10 watts through 100 watts).

3. MIC GAIN CONTROL:

This control adjusts the microphone gain in the transmit and PA modes. This feature is designed for use in a
h-ambient noise environment or to maxize talk power.
4. ON/OFF VOLUME CONTROL:
Turn clockwise to apply power to the radio and to set the desired listening level.
5. SQUELCH CONTROL:
This control is used to control or eliminate receiver background noise in the absence of an incoming signal.
For maximum receiver sensitivity, it is desired that the control be adjusted only to the point where the receiver background noise
is eliminated. Turn fully counterclockwise then slowly turn clockwise until the receiver noise disappears. Any signal to be received
must now be slightly stronger than the average received noise. Further clockwise rotation will increase the threshold level which a
signal must overcome in order to be heard. Only strong signals will be heard at a maximum clockwise setting.
