could not open /dev/kbd to get keyboard type US keyboard assumed could not get keyboard type US keyboard assumed Subject: 2500xlt cellular mod NOTE:since receiving this mod, I have been told that there are two different pc board designs for the 2500xlt Make sure you have the unit that corresponds to this mod This is the cellular restoration mod for the Bearcat 2500xlt The paper this was taken from had no Copyright notice on it so here it is The diagrams included on the paper make things much easier to understand 1 Remove the antenna and battery pack from the BC2500XLT Lay it on its face on a soft cloth or towel, bottom of the radio facing you Remove the two upper (black) and two lower (chrome) screws 2 Carefully pry the back loose from the radio and lift it off Similarly, grasp the visible circuit board by the edges and carefully pull it away fron the radio just far enough to separate it from the white (11 pin) Molex connector Do not stretch the remaining ribbon connector Lay the board alongside the radio 3 Locate microprocessor chip "Uniden UC-1513A", and the cluster of chip resistors marked "104" below it (see diagram) Using a magnifier and fine-point soldering iron, unsolder the lower-left-most chip resistor and move it one place to the left, soldering it in place Reassemble the radio by reversing steps 1 and 2, and test it by entering 879.990Mhz. Search steps in this range will be the correct 30 KHz | | | | | UC-1513A | | | | | |Number of pins on diagram may be wrong.| |Make identification by resistor matrix.| | | ------------ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------| | | | | | | | | | | --------| | p = solder pad | | | | | | c = a component | | | --------| | ----- R = the resistor to move | | | ---- | | \ X = the new location | | | / \ | | \ for "104" p | p-c-p p | p-c-p | / | / / / | | | | | / | / | / | p X p-R-p p p-c-p p-c-p p | | | | | | /--\ |----- |-------------------------- --- ^ ^ | |move this resistor "104" to the left | | | <-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<--| Russell Keating, N9LIL ------------> Send email To: russell1  Amsterdam   CLICK HERE AND YOU CAN VOTE FOR OUR FREE WEBSITES IN THE TOP 100 LIST  A TOP RANKING?
