I just did the upgrade and it really, really improved reception of the Detroit Police/Fire trunking system. The system now is received as well as any APCO-25 system even though the signals from Detroit are quite weak in my location at 10 Mile and Greenfield!
On the old version, all the Detroit transmissions would degenerate into digital hash in the midst of each transmission. Now, the Detroit system is perfectly listenable!!!
I can also verify that the PRO-96 is now vastly superior to the Uniden scanners in receiving Detroit.
Thanks Radio Shack! Your engineers are tops! I had given up hope of EVER hearing the Detroit system!
