Motorola Astro Spectra Flashcode Decoder: A Step-by-Step Guide

The Motorola Astro Spectra series of radios has been a popular choice among users, but one of its limitations is the inflexibility when it comes to changing the band limits. However, with the right tools and knowledge, you can unlock this feature using a flash code decoder.

To begin, you need to access the file that contains the band limit information. This file is typically write-protected, so you'll need to use a hex editor to modify it. The two files of interest are Astrop.odb for mobiles and Strop.odb for portables.

Once you've accessed the file using a hex editor, search for the original band limits on the ASCII side of the document. Make any necessary changes to the band split by replacing the existing values with the new ones.

After modifying the files, be sure to save your changes and then reselect the 'read-only' attribute using the same method. This will prevent accidental modifications to the file.

If you're using a later version of Astro RSS, you may find that it's a combined portable and mobile version. In this case, there are seven different places where you can modify the band limits.

For those who want to change the flash code on their radio, there is a Flash Code Decoder available online. This tool allows you to decode the flash code and determine what options are included in each upgrade.

Before attempting to upgrade your radio's flash code, be sure to check out the Flash Upgrading Primer for more information. You'll also need to have SmartRib software installed on your computer.
