RS/GRE PRO-92 Handheld Scanner

The Pro-92 was manufactured for RadioShack by GRE and was the first handheld LTR trunking scanner.

There are 3 firmware versions of the Pro-92. The first, 1.00, introduced in 1999 as the Pro-92, has sub-audible data Motorola trunking that had the tendency to lose active Motorola transmissions. The second, 3.25, introduced in mid 2000 as the 92A, fixed that with control-channel trunking. And the third, 3.28, introduced in late 2000 as the 92B, is essentially the same as the 92A with minor SAME weather alert improvements.

General Specifications

Features

Rebanding supported?
- Original Version: YES
- Versions PRO-92A or B? NO
- The difference between the 3 versions:

The A and B versions use control channel trunking, a data-only channel that gives instructions to the radio telling it what channel number to tune to based on a bandplan. The bandplan is hard-coded into the radio, so you can't change it. On the contrary, the original version used the sub-audible datastream contained in the voice channels to get talkgroup information, not the control channel, meaning all you need is the rebanded voice frequencies.

- How to tell the difference;

Turn the radio over and look on the back for the information sticker. In the upper right-hand corner, it will list the catalog number. If there is no A or B next to it, you have an original PRO-92.
During power up, press 3. This shows the firmware's version number. If you have version 1.00, you have the original version.

+** Versions PRO-92A or B? <span style="color: red">NO</span>
 ** The difference between the 3 versions:
-** The A and B versions use control-channel trunking, which tells the radio which voice channel to go to, based on the band plan coded into the firmware. The first version PRO-92 uses the sub-audible data stream contained in the voice channels of Motorola systems. The sub-audible data tells the radio what talkgroup is currently active on a given channel. In this case, the frequency that has the control channel would need to be locked out since the scanner would stop on it every time, and the radio doesn't make use of the data contained in it.
