I have three XPR4550's that I use on Amateur DMR. Got these at a bargain off of Ebay. The only catch was that they were in the 450 - 512mhz spread. A hex edit was and easy enough fix to bring the band spread down to 440 - 512mhz. The only trick is that you have to always modify the plug that is saved on the computer, or in my case on a memory stick. Then load the modified code plug to the radio. (If you READ a code plug out of a 450mhz radio, the software will reset the lower limit back to 450mhz when reloading back to the radio.)
I have been using the CPS 7.0 version for my programming. The only downfall was that with CPS 7.0, it would not read any of the newer DMR code plus from the NCPRN site. So I finally broke down and upgraded to CPS 12.1. It reads the on line code plugs fine. I opened up the newly down loaded code plug and my own radio code plug, both at the same time. I cut and pasted what I wanted from the down loaded plug to mine. Re-saved my own code plug to the memory stick.
Here is the problem and what worked for me. When I went to load the code plug with CPS 12.1, it came up with the error message that I had to enable (buy) the 25khz entitlement key. I had another older laptop with CPS 7.0 still on it. I took my updated code plug file and it would still read on the older CPS 7 program. It would also load my modified code plug into my radio with the 25khz analog 440 repeaters.
