9.  a.  C13.8 Vdc to the DC Input of the Repeater. For the DC Power Jack, the center connection is po) 

 

and the outer sleeve is negative(-).  

 

b.  Connect the USB Connector of the PC Programming Cable to the mating USB Connector on the radio assembly. 
C. Connect an RJ-12 Connector and Cable with trimmed leads to the mating connector on the Radio Assembly.  

 

 

 

 

 

10.  Start the RLR-PCPS Programming Software.  Select Repeater/Read to Read the radio information. 
 
11.  Verify the TX Frequency, RX Frequency, and RAN Code.  

 
 
RECEIVER 

RX VCO Band and Reference Oscillator Adjustment 

NOTE: 

After each adjustment, click on the “Program Repeater” button then the “Read Repeater” button to save 

and read the radio information. 
 

1) 

Go to the “Alignment” tab and click “Frequency/Power” then “Center Frequency on Repeater Frequency”. This will 
load the repeater local oscillator frequency into the RX synthesizer.  LO(freq) = RX(freq) 

– 43.650 MHz. 

 
2)  Measure tuning voltage on TP102. The VCO tuning voltage will range from about 1 Vdc at 450 MHz to 4 Vdc at 

470MHz. 

 

 

 

 
3)  Connect probe from the Frequency Counter to the Receiver Local Oscillator test point TP101 and measure the 

Repeater LO Frequency.
