1.

Remove the covers from the unit and locate coil T6 close to the LC7131 PLL chip.

Unsolder the pins of T6, and remove it from the circuit board.

2.

Solder the expanders Green wire into the hole of T6 that connects to capacitor C35.

3.

Solder the expanders White wire to the hole across T6 that connects to capacitor C12, and resistor R37.

4.

Solder the small 100 pf capacitor (included in kit) across the outer terminals of the ceramic filter CF-1, located close to coil T3. Note: if a squeeling noise in the receive is present, try soldering a 22 pf capacitor in series with a 1k resistor across CF-1 instead of the 100 pf. (See Uniden PC-33)

5.

Solder the expanders Red wire to the switched +13.8VDC at the ON/OFF switch.

6.

Solder the expanded Black wire to circuit board ground.
