-
- 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.
