Progress Report: Going great. Found Win500 Software on an old laptop. Fired up the Program on the laptop. Looked under "Help" and found my Registration Name and Activation Key. Cut and pasted the Name and Key to a Wordpad text file. Copied the text file to the Win500 Program Folder. Copied the Win500 Program Folder to a USB portable hard drive. Moved the USB portable hard drive to a Win 8.1 32/64 desktop. Copied the Win500 Folder from the USB drive to the desktop C: Program Files(x86) Folder. Opened the new Win500 Folder and created a Desktop Shortcut to the Win500.exe File.
Clicked on the shortcut and shazam! Win500 V01.94 opened up. Oops, says I have a 30 day trial? Went into the Win500 folder and found my text file containing name and key. Cut and pasted the name and key into the open Win500 page. Another shazam! Program accepts my name and key. Time to search the cable bonepile for a suitable USB to 500 cable. Found a likely suspect and hooked it up. Yahoo! Win500 says use Port #4 (or something like that). I try a Download from Scanner. Zippo! First thing I do is go to the Phx PD System and LockOut all the C (HOT) TGs. Then I make sure just the same TGs that are scanning on a nearby 996xt are open in the 500 Program.Then I looked at the General Settings and the Extended Settings. I don't remember changing any of the settings in the past, but in the Extended Settings I hit the "Default" button, just to make sure. I didn't see anything change. Then I Upload to Scanner.
Once again, I see what some have said is not possible. Both the 996xt and the GRE500 are locking onto Phx PD transmissions virtually SIMULTANEOUSLY, and HOLDING on those transmissions for the DURATION of the open mike. Some of these "lockons" are longer than 30 seconds! It's a different topic than this thread, but I can't help saying it again. Before I acquired the "E" to my first HP-1, the GRE500 never locked on a Phx PD transmission for more than 8 seconds, and rarely longer than 4 seconds, which is, of course, not conductive to pleasurable scanning.
Now, back to John, Peoria. Looking at General Settings, and Extended Settings, I believe they are all set to "default" values. Looking at the "System Frequencies" for my setup for the Phx PD, I see only four entered: 867.212500, 867.962500, 867.175000, 868.162500. This info will probably not make a lot of sense if you don't have the Win500 Software.
