Looks like you will also need the Kenwood KPG49D software. Really easy to use... Since it is a firmware 1.5, you may see an alert that it is not a software target radio. Disregard that alert and continue. Hint: when you get the software loaded, the radio connected to your new USB cable and the COMM PORT checked as active from the setup tab... hit the "MODEL" tab in the software menu screen. Click on "Model Information" and a drop down menu appears. Normal settings would be - Model Type: TK880 Frequency: 450 to 490 Radio Format: Conventional Option Board: none Fleet Sync Enhanced Function: (Important that this check box IS NOT CHECKED)
