The Radio Shack Pro-94a is a 1000 channel radio scanner. One of the biggest problems with this scanner is that there is no computer programming mode. The following information below will show you how to directly access the EEPROM inside that holds all user-programmed frequencies. By doing this you can now use a computer to swap out an entire 1000 frequencies within a few seconds. This method is actually much faster, and a lot more reliable, than the normal computer programming sequences found in other Radio Shack scanners and elsewhere.
