Can someone tell me how to perform the channel mod? I have the Uniden/President Grant with the push buttons in the middle and 6 knobs on the left. Thanks in advance, 814 |

If you have the 8719 PLL... (SWITCH 1) Connect the "middle" pole of a SPST toggle from pin 12 on the PLL and the other to pin 11 on the PLL. (SWITCH 2) Using a second SPST toggle, connect the "middle" pole to pin 10 on the PLL and the other pole to board ground. I say middle because there are only two poles but they are offset somewhat. The "middle" pole is the closest to the middle of the underside of the toggle switch. When you mount the switches, the pole closest to the end of the switch goes towards the bottom. This is important for reading the freq roadmap correctly. This gets you 26.815 - 28.045 Steve Tech181 Tech181@copperelectronics.com |

If you have the MB8719 PLL... Install a SPDT switch. Connect the top pole of the SPDT switch to board ground. Cut the board trace coming off of pin 11 on the PLL and seperate the trace. Solder a 4.7K resistor across the seperation you just made. Connect the middle pole on the SPDT switch to pin 11 on the PLL Connect the bottom pole on the SPDT switch to pin 9 on the PLL.
