3.0 INTRODUCTION 
This section explains the basic operating procedures for the RCI-2950 DX / RCI-2970 DX Amateur 10 
and 12 meter dual band mobile transceiver. 
 
3.1 CONTROL AND CONNECTIONS 
 
3.1.1 FRONT PANEL 
Refer to the above Figure 3-1 for the location of the following controls. 
 
1. FREQUENCY SELECTOR 
This control is used to select a desired transmit and receive frequency. 
 
2. RF POWER CONTROL 
This...

 
- 5 - 4. ON/OFF VOLUME CONTROL    
This knob controls the volume and the power to the radio. To turn the radio on, rotate knob clockwise. 
Turning the knob further will increase the volume of the receiver. 
 
5. SQUELCH CONTROL 
This switch is used to eliminate background noise being heard through the receiver which can be 
disturbing when no transmissions are being received. To use this feature, turn the switch fully 
counterclockwise and then turn clockwise slowly until the background noise is just...

 
- 6 - 16. SWR BUTTON (SWR) 
This control is used to check SWR. 
 
17. SCAN BUTTON (SCAN) 
This is used to scan frequencies in each band segment. The OPERATION segment of this manual 
provides detailed information on using the SCAN control. 
 
18. MEMORY BUTTON (MEM) 
This button is used to program memory channels. Detailed information on how to use this control is 
provided in the OPERATION section of this manual. 
 
19. ENTER BUTTON (ENT) 
This is used to program frequencies in memory. See the...

Figure 3-2 represents the location of the following connections: 
  
 
Figure 3-2 Rear Panel 
 
1. ANTENNA 
This jack accepts 50 ohms coaxial cable with a PL-259 type plug. 
 
2. CW KEY 
This jack is for Morse code operation, To operate, connect a CW key to this jack and place the MODE 
switch in the CW position. 
 
3. EXT. SP. 
This jack accepts 4 to 8 ohms, 5 watts external speaker. When the external speaker is connected to this 
jack, the built-in speaker will be disabled....

 
- 8 - 3.2 MICROPHONE 
 
1. PTT SWITCH 
The receiver and transmitter are controlled by the push-to-talk switch on the microphone. Press the 
switch and the transmitter is activated, release switch to receive. When transmitting, hold the 
microphone two inches from the mouth and speak clearly in a normal voice. 
 
2. REMOTE UP/DOWN SWITCH 
An operating frequency can be incremented or decremented simply by pushing either of these buttons. 
 
3.3 OPERATION 
 
3.3.1 CHANNEL SELECTION 
Frequency selection...

 
- 9 - 3.3.5 SPLIT FUNCTION 
This function enables you to offset the transmit and receive frequencies for FM repeater operation. The 
transmitter frequency can offset either higher or lower than the receive frequency. To split frequencies, 
press the MAN button and the Split button to select either +/- split frequency. If the + split is selected, 
the transmit frequency will be higher than the receive frequency. If - split is selected, the transmit 
frequency will be lower than the receive frequency....

 
- 10 - In order to achieve maximum radiated power, it is important that your antenna be in good condition, 
properly adjusted and matched to your transceiver. The built-in SWR (Standing Wave Ratio) meter 
allows you to measure your antenna condition. To operate this function, connect your antenna to the 
transceiver antenna connector, set the mode switch to AM and adjust the MIC GAIN to minimum. 
Select a frequency near the middle of the band you plan to use most. Activate the SWR function and 
press...
