The Pro-106 is manufactured for Radio Shack by GRE America Inc.

The Radio Shack is a Digital Trunk Tracking scanner which boasts the ability to track APCO 25 digital trunking systems, in addition to following Motorola type I/II systems, LTR and EDACS trunking systems. It is very similar to the GRE PSR-500.

The Pro-106 is functionally identical to the PSR-500 and uses the same software and cables. Firmware updates are NOT compatible between this radio and the GRE PSR-500 though.

Note: Testing has shown that the frequency range 796.9975 to 805.9975 MHz is blocked on this scanner.

  • Please see the Connecting scanners via USB article for USB cables to connect your PC to the scanner

Discriminator Tap

  • There is also a built in data dump which can be enabled with "CCDump" in the Func-Global "super expert" menu which may meet many users needs when used with 3rd party software which already supports this data. When CCDump = "Yes" most control channel and weather SAME data is dumped to the PC/IF port for use with the USB cable. This may save soldering and warranty issues for most users.
