Hours 3:03:00 Total Build Time: 31:40:00 Nov 13, 2011
Started working on page 50 of the manual today. The first item to build was the PLL (phased lock loop) upgrade. The upgrade includes a thermistor that will keep the frequency more stable on the K2.

| PLL Upgrade Kit |
The PLL upgrade kit consisted of some wire, several resistors, a thermistor, and the circuit board.

| Parts for the PLL Upgrade kit |
Man these parts are small. Most of the components of the PLL upgrade kit were 1/8 watt resistors.

The PLL upgrade kit replaces on of the resistor packs RP3 on the RF board. Wires were soldered onto the board so it could be soldered into place as RP3.

Once the PLL upgrade board was assembled, it was soldered into position at RP3.

Today I finished up on the second to the last step on page 51 of the manual. Next time I start working on the project, I will be installing capacitors on the RF board.
