This page contains information on applying the BCT8 Rebanding Update. Read the following sections carefully.

Installing BC_VUP v2.0.0.7

You must install the latest version of BC_VUP in order to apply the rebanding update. To install the update, click and save the file to a directory on your hard drive. Then, unzip that file and run BC_VUP_V2.0.0.7.exe and follow any prompts you receive. The installer will place a BC_VUP icon on your desktop.

If you have other Uniden scanners, you can use this version to apply updates for those scanners, as well (i.e. if the instructions for the other firmware update calls for an earlier version such as or, can be used with no problems).

Applying the Update

  1. Download the update by clicking Save this file to a known location on your hard drive.
  2. Extract the BCT8_V1_60.scn file from the zip archive. Do not rename this file.
  3. Plug your scanner into the PC's serial port (or USB-->Serial adapter if your computer does not have a native serial port). Note that you must know what COM port the scanner is assigned to in order to proceed.
  4. Click the BC_VUP icon on your desktop and follow all instructions that appear.
  5. When prompted, select the BCT8_V1_60.scn file you downloaded above.

Update Troubleshooting

Follow these tips to troubleshoot any update problem you encounter:

Entering a Rebanding Table

To set a bank as a rebanded system, set the bank to MOT Type I or Type II Custom (E1-CUS or E2-CUS). Then, apply the rebanding table as follows:

For standard rebanded systems, you need to set Band Plan 1 and Band Plan 2 as:

Band Plan Base Freq (Lower) Base Freq (Upper) Offset Polarity Spacing
1 851.0250MHz 854.0000MHz 440 + 25 kHz
2 851.0125MHz 868.9875MHz 0 + 25 kHz

  1. Select the Trunking Programming mode and the bank you want to change.
  2. Use [Δ] / [∇] to choose Motorola Type 2 Custom (E2-CUS) or Type 1 Custom (E1-CUS) and press [E].
  3. Use [Δ] / [∇] to choose "bASE" then press [E].
  4. Use [Δ] / [∇] to choose the Configuration Block Number (1 to 6), and press [E].
  5. Use [0]- [9] to enter a new Base (Lower) Frequency, then press [E]. Then Upper Frequency is displayed.
  6. Use [0]- [9] to enter a new Upper Frequency, then press [E]. Then Base (Lower) Frequency is displayed.
  7. Press [Δ] to change to entering the Spacing Frequency.
  8. Use [0]- [9] to enter a new Spacing Frequency, then press [E].
    Note: You can only enter within a range of 5 - 100 kHz, and 5 or 12.5kHz multiples. If a Base Frequency hasn't been set yet, the setting of Spacing will not be accepted.
  9. Press [Δ] to change to entering the Offset Channel.
  10. Use [0]- [9] to enter a new Offset Channel, then press [E]. The display changes for selecting the Polarity (PLUS).
    Note: You can only input within a range of 0-1023. If a Base Frequency hasn't been set yet, the setting of Offset will not be accepted.
  11. Use [Δ] / [∇] to choose the Polarity (PLUS or no PLUS). The Polarity (no PLUS) is displayed below. (The "POL" is flashing.)
  12. Press [E] to store the Polarity. Then the Offset Channel is displayed.
  13. Press [RESUME] key. The scanner returns to the Configuration Block setting screen.
  14. Use [Δ] / [∇] to enter the next Configuration Block Number (1 to 6), and press [E]. Then, repeat from step 5.
