I have two DTR 550 radios that were picked up of off ebay. These are the fixed antenna version. They work great. One of them has the name "Josh" on the screen, and the other has a number displayed. Since no one using the radios is named Josh, I decided to invest in a programming cable, since the CPS for the DTR's is free.
The cable arrived today and I hooked it up, and installed the CPS. When I try and read either radio, I get an error message stating the firmware is not compatible with CPS.
Obviously these were programmed at some point. I doubt the ship with Josh on the main screen. I've STF'd here, and googled for DTR550 programming, firmware, etc., but I can't find any information beyond sites that sell DTR accessories. Do I need an earlier version of CPS? 1.0, perhaps? I have 2.0. Can I do a firmware upgrade?
