Ranger RCI-298595dx High Power Cb Tranciever Manual

 - 11 - 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 the PTT button on the microphone. A bar on the meter is an indication of the 
antenna matching. If there is no bar, it indicates that your antenna system is perfectly matched. The...

4.0 INTRODUCTION 
This section explains the basic programming procedures for the RCI-2985DX / RCI-2995DX Amateur 
10 and 12 meter dual band base station transceiver. 
 
4.1 FREQUENCY SELECTION 
Frequency selection in the RCI-2985DX / RCI-2995DX can be accomplished using anyone of the three 
following methods: 
 
(1) The first method of frequency selection is through the use of the SHF (Shift) key and the (V) Up 
and (W) Down arrows. To accomplish this, press the SHF button until the cursor...

 - 13 - The upper and lower scan limits have now been programmed. To activate the scan feature, return the 
radio to manual operation and press the SCAN button. If the display shows “SCAN+”, the radio will 
scan from the lower limit to the upper limit. If “SCAN-” is displayed, the unit will scan from the upper 
limit to the lower limit. To change from SCAN+ to SCAN- or vice versa, press SCAN. 
 
 
NOTE 
When programmed, the upper and lower scan limits will 
also act as the upper and lower operating...

NOTE 
The FM repeaters may require a subaudible (CTCSS) 
tone be transmitted to gain access to the repeater. The 
RCI-2985DX / RCI-2995DX is not factory equipped with 
a CTCSS encoder/decoder. 
 
 
The split frequency function offsets the transmitter frequency either above or below the receive 
frequency by a user programmable amount. In the following example, programming of a 100 KHz 
offset will be described. Before attempting to program the offset frequency, ensure that the radio is 
operating...

5.0 INTRODUCTION 
This section explains the technical theory of operation for the RCI-2985DX / RCI-2995DX Amateur 10 
and 12 meter dual band base station transceiver. 
 
5.1 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, Q29, Q32, 
Q33, Q34, Q36, Q37, Q38 and L16. The PLL circuit is programmed by the rotary channel switch GPS-
