Subject: BC2500XLT cellular mod >Does anyone know if the New bearcat BC2500 can be >modified to recieve in
the Cellular phone band??? > >Do you know and can you tell me what the MOD involves? I have never tried this
mod I have one page which I received from Grove about this modification for cellular restoration The page
notes that the modification may not be really necessary, because you can still hear the cellular
communications in the image frequencies 21.6 MHz higher that the true cellular ranges Thus, you will hear
cellular calls in the 894.01 to 915.60 MHz range on your BC2500XLT without modification If you really want
to do the modification, here are the step-by-step directions Most of what follows is copied verbatim from
the Grove sheet, which does not have a copyright notice on it Therefore, I'm assuming it's OK 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
from 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", the speaker, and the battery terminals Below the microprocessor and above the speaker and battery
terminals, locate the cluster of chip resistors marked "104" 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.
Cellular restoration is now complete Reassemble the radio by reversing steps 1 and 2, and test it by
entering 879.990 MHz Search steps in this range will be the correct 30 kHz As I said, I have not tried this
modification, so I can't testify to whether it really works Grove states that Grove Enterprises assumes no
responsibility for damages or other liability resulting from attempting to duplicate this procedure It is
possible (probable?) that this modification may void your warranty Also keep in mind that there are at least
two versions of the BC2500XLT I don't know whether these modification applies to all versions Finally, the
obligatory note to remind you that monitoring mobile telephone conversations, including cellular, is against
federal law.
