Uniden BCT15 Firmware Revision Notes 1.06.00

As part of Uniden's commitment to the continued support of the BCT15, Uniden has, from time to time, issued firmware updates. This update contains major enhancements to the BCT15 that directly reflect requests from our customers. Please take a few minutes to read all of these instructions before applying the update.


What is Changed by This Update?

Previous Version v1.03.04

This firmware update made the following improvements to your BCT15 scanner.

Backing Up Your Scanner

While it doesn't happen often, it is possible that applying a firmware update could affect some of your scanner's programmed settings or systems. We recommend you make a full backup of your scanner's programming and configuration before you apply the update. Follow these quick steps to make a backup of your BCDT15 programming using Uniden Advanced Scanner Director (UASD):

  1. Install (if necessary) and run UASD.
  2. From the main menus, select "Scanner View".
  3. At the top of the window, select Setup --> Options.
  4. Set the COM port to the port you've connected the BCT15 to and select the baud rate that matches your scanners Settings-->Set Serial Port-->Set Baud Rate-->Front Port setting and then click OK.
  5. Select "Read from Scanner" from the top function bar.
    • The software will begin to read the contents of your scanner.
  6. When UASD finishes reading from the scanner, select "Save to Data Base" from the top function bar.
  7. Make sure the check boxes next to "Save Configuration", "Save Location Alert Systems", "Save Selected Systems", and "Replace existing files with same names" are checked, then enter a name for your configuration in the text box next to "Save Configuration as:", then click OK.

Applying the Update

Before applying the update, you need to download two files. The following files are required for this update:

  1. Navigate to the location where you saved the above files and unzip the files (they will be BCT15_V1_06_00.scn and Install_BC_VUP_v2.0.0.7.exe).
    • If you have not previously installed the BC_VUP firmware updater, run the "Install_BC_VUP_v2.0.0.7.exe" program. This installs the firmware version updater on your PC. (Note: If you have previously installed this version, you do not need to install it again.)
  2. Run the installed application. When prompted, select "BCT15_V1_06_00.scn" in the directory you used in Step 1.
    • Since this update does not change the major version number, you do not need a registration code to apply this update.

Update Troubleshooting

Follow these tips to troubleshoot any update problem you encounter:

UASD After the Update

While you can continue to use UASD after the update, note that the new features incorporated into this update have not yet been applied to UASD. So, new settings are only available through direct entry at this time.

Adjusting AGC Parameters

To access these settings:

  1. Turn on the AGC function.
  2. Tap F then hold VOL for two seconds. The scanner displays the current ANALOG AGC RESPONSE TIME parameter setting (see below for option details).
  3. Rotate the scroll control to change the setting.
  4. F+rotate the scroll to select another setting.



Range: -4 to +6 (0 is default)

This parameter determines how frequently the AGC factor updates. Decreasing this value makes AGC respond faster, but could result in "pumping." A higher value decreases the response time.


Range: -5 to +5 (0 is default)

This parameter determines the reference level that AGC attempts to adjust the volume to.


Range: 0 to 15 (6 is default)

This parameter controls the total dynamic range of the AGC adjustments. A larger value allows a wider variation in volume.

Motorola 800 Custom Band Plan (Rebanding)

This update adds the ability to create a Motorola 800 MHz site using a custom band plan. When you create a site that has been rebanded to use the frequencies newly added for use by the FCC, you have the option now of selecting 800MHz Custom as the Motorola site type.

Once you create the site, you can set the custom band plan as follows:

  1. In the Site setting menu, select Edit Band Plan.
  2. Select the band plan entry to edit.
  3. Set each of the following entries for the band plan:
    • Set Base Freq (Upper and Lower)
    • Set Offset
    • Set Spacing

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
