Well the Cobra 148 NWST with the MMB8719 PLL can be modified,But with two switches, 1 get two spst switches 2 On the solder side of the board, locate the trace to pin 14, and cut,then solder a 4.7k 1/4 watt resister across the cut trace, next solder a piece of wire to the trace that still leads directly to pin 14, then solder another wire to pin 9, then solder the wires to a switch. 3, next solder a wire to pin 10, and solder one wire to a ground on the board, solder these to a switch also, thats it, do not try to do the final switch to pin 11 and 12 as you would with the regular MB8719 mod, this will take out the PLL, the MMB8719 is different, You will replace PLL if you try. 4 If you want to do the standard 148 mod to the 148 NWST, you will have to replace the MMB8719, with a MB8719, than its just like its always been. Just remember, were not suppose to use those extra freqs, This is just for your information, since I have not seen any good information for the nightwatcher series 148s, have fun. |

Is there any other frequencies that or pins that can be jumped on this pll? With this mod the freqs end at 27.445 and jump to 27.645--- I want 27.555--- I was hoping there was an easy way to do this. Any ideas or new additions to this pll out there? |

How about the RCI MB8719? Can it be modded like the original or must it be swapped also? |
