Trunk Conversions

David L. Wilson wrote the following programs to help perform the numerical conversions described in his June article “Those Strange Motorola II and Ericsson EDACS Talk Groups.” The processes are different for the two systems, but they involve converting hexadecimal and binary numbers to decimal numbers to help understand the structure of a particular trunked system’s talkgroup organization.

For each mode of trunking Wilson provides two approaches. One program uses keyboard input (EDACS-K) and another uses text file input (EDACS-F) to do the EDACS conversion described in the article. One program uses keyboard input (MOT-K) and another uses text file input (MOT-F) to do the Motorola Type II conversion described in the article. They will run under DOS or under MS-Windows. To install each of the two programs in MS-Windows, do the following for each:

1. Click on "My Computer", click on the hard-drive, and make a folder on the hard-disk by right-clicking in that window, select "New", then "Folder".

2. Name that folder (right-click on it, select "Rename"). I suggest "Trunk Convert"

3. Save the .exe program file and .ico icon file to that folder after downloading.

4. Create a link to the program by right-clicking on the desktop, select "New", then "Shortcut", and use "Browse" to find the .exe file saved in the folder above. Windows should find the icon then by itself.

The programs should be fairly self-explanatory, says David.
