I recently updated the DSP.APP on my Pro-2096 to the latest update of U1.4.I see on the RS download page there was 3 prior updates.Do I need to download them also or does the 1.4 cover everything? I think the update took seeing it now reads the DSP.APP as U1.4 on the startup screen.Trunking is all new to me and I am trying to get the hang of it.I have also got the ARC96 software to try to make things easier.I still have yet to hear any trunking stations.Any help would be appreciated.
