Section 2
INSTALLATION #7
This section describes the installation to 858 SSB radios with the PLL circuitry contained on a separate board.

1. Remove the transceiver and 400 cases.
2. Locate and identify Pin 11 of the PLL Chip-normally close to the channel selector in
the transceiver (see Fig. 10). Solder the center of Coax #1 to Pin 11 of the D858 PLL Chip. Use caution and avoid excessive heat as it will damage the PLL Chip.
3. Locate and identify 8154 15K ohm resistor that connects Pin 2 of D858 and Pin 3 (see Fig. 10).
4. Remove the one side of 8154 that is connected to Pin 2 of the D858 PLL Chip and install the center of Coax #2 to this lead of 8154 as per Fig. 10.
5. Connect the ground shields of both coaxes to ground. (Example: see Fig. 10).
CAUTION: Avoid excessive lead length.
6. Locate and identify C508, a 33 mfd capacitor, and install a 20-22 gauge jumper wire across it's leads to remove it from the circuit.
7. Connect the black wire to radio circuit ground near the power supply or modulator section.
8. Connect the red wire to a 12V source in the radio.
9. Remove TR-22 to comply with FCC regulations. Refer to Programming Section and
proceed.
