Uniden PC404 80 channel Mod

Hi :D ,does anybody know the procedure for converting one of these from a 40 channel midband set to make it also have the UK 27/81 band aswell? i know if i do a direct swap with the tc9106 for a tc9119 it will give me the UK 27/81 as the pinouts on both pll's are the same,but the pcb in the Uniden 4...

Stalker XX Squelch Delay

Hi Rick,yes you are right there are 2x vr's on the pc-547 board 1 is for the channel 9 squelch gate & the other is the main squelch.So which componant would you suspect to be the problem on the main pcb for the open/closing slowness on the main squelch?

Hi warhorse :) yep i did the mod & it had the reverse effect as you suggested it might,coz when i swapped the transistor rx sensitivity went down so i have replaced the 2sc1730, was worth a try,cheers for your input on this,Shaun :D
