For the 96/2096 CPU/FW 1.5 was a specialized upgrade for ONE area as a test. The last full release was 1.4 Last DSP is 1.4
With 1.4/1.4 The 96 is actually a very good machine on P25 Phase I 800 MHz Simulcasts (Excluding the EFJ systems). *Especially after doing the minor internal screw adjustment*
digging out my old pro 96, friend has one, and wants to use it, but I think his firmware is 1.0 any Idea on links for last firmware update they did.
I know I'm reaching on that one.
The LINK is in the WIKI section of Radio Reference above for the Pro96 radio. U1.4 WAS the last update .. as he said above, the 1.5 was for a special system in one State (Michigan?)
