Before we go any further, let's first validate you got the right scanner for your desired app. The 163 is an analog-only scanner, and won't copy digital systems, which many metro areas are moving towards these days. Go up to the blue toolbar under the RadioReference logo, float the mouse over
Database then select
Database Home. Using the pulldowns that you will see, find the areas you wish to hear. Supply the URL(s) in your reply.
Now when you say 'PC Cable' I'm hoping you mean either the RS or GRE USB cable; PCs these days don't have serial ports, so this is a necessary step. Along with that, you need to install drivers so that the PC will recognize the USB device. The 2 cable SKUs are found in this article (anything in blue is a link)...

Have the drivers been installed? Are you sure that a COM port has been assigned that is available? What OS are you running on the PC?
