What is the difference between the Pro 92 & the A or B rev??

I found this post from 2002. Is there anymore info I need to know. Was the problem only related to trunktracking? I plan on using the 92 for conventional most of the time. I have others for TT.

Thanks

The PRO-2041 and PRO-64 are GRE made.

The PRO-92 was GRE's first trunktracker and was sold in two versions. The initial release used subaudible tracking and did not work well on some Mot systems, especially large busy ones. The later versions used control channel tracking and worked better on most systems. The newer PRO-93 and PRO-95 GRE trunktrackers work very well and I prefer my PRO-93 to my BC245 for trunktracking.

Just a little follow up

http://support.radioshack.com/support_electronics/doc66/66369.htm#200-0522

Product: PRO-92 Multi-trunking Scanner Cat. No.: 200-0522
Question: What is the difference between the 200-0522, 200-0522A and 200-0522B versions of the PRO-92?
Answer: The primary differences are either in the firmware version and/or the trunked scanning method.
PRO-92 200-0522
Firmware: Version 1.0
Trunked Scanning: Low Speed Handshake
PRO-92 200-0522A
Firmware: Version 3.xx
Trunked Scanning: Control Channel
After introduction of the PRO-92, we learned of some instances where it didn't perform to expectations on some Motorola trunked systems. Based on this, a few customers have raised concerns about the quality of the PRO-92. An update to the software (changing the scanning method from "Low Speed Handshake" to "Control Channel") improves performance with these "troublesome" trunking systems. Effective immediately, we are offering this upgrade for the price of labor only. You would need to take the radio to your local RadioShack store and have them send it to the service center. Through cloning, reasonable efforts will be made to retain the programming in the scanner's memory.

Warning: Do not send a scanner that currently works fine on your local trunked systems just because it has version 1.00! If the scanner already works well in your area, this update is not needed.

The only significant difference between the 200-0522A and the 200-0522B is that the manufacturing location changed.

PRO-92 200-0522B
Firmware: Version 3.xx
Trunked Scanning: Control Channel

Not anymore I wanted to know what the differance was. I found that info and posted it. I've read more into how excactly it affects the 92. I'll cut & paste the info later to keep everything in this thread (it will be easy for me to find when I forget :lol: )

Okay Grog,

There are pleanty of us who still own and use them. I have one of each, (well not really, I have a Pro-92 and a Pro-92B and also a Pro-2067 which is equivelent to the "A" model.) So if you come up with something you want to know, just ask away. :wink:
