Evidently by tapping the discriminator, manually pausing on a control channel and feeding that information through a serial cable to a program like UniTrunker, the 92
should be able to handle this. However, I do not think the Pro-92 is supported by UniTrunker currently. The Pro-2052 is supported (which I thought was the base version of the Pro-92, but our wiki here:
Pro-92 says that this scanner was produced by GRE whereas the Pro-2052 was produced by Uniden as seen here:
Pro-2052). So it might not be supported by software currently, which would mean you might be SOL. However, I do not know if any other software supports the 92. But, you would definitely need to tap the discriminator (an article is found
here on that mod). Let us know what you figure out.
