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.
