Issues programming CDM750 using Chirp and CPS

[jbesedic]

I have two CDM750 that I want to program. I can get into Chirp with no issues and put the radio in the ham band using Waris module.

The issue is the CPS version R06.12.02 or R06.12.09 will not read the radio. I've tried loading the sample file and writing to it but for some reason I cannot write the file.

To better explain it I created a video and posted it to youtube.com

If someone knows what I am doing wrong please reply. I've done with exact method for my CDM1550ls with no issues at all.

Here is a youtube video showing the issues

Why are you using CHIRP? I’ve never known a Motorola radio to be the least bit compatible with CHIRP. A simple hex edit within the Professional CPS is all you need to go out of band. With that said, your eeprom probably needs to be replaced. The professional series radios have a limited number of times they can be programmed.

Invalid tuning values. Invalid serial number. Basically used a chirp module to perform depot level functions and did it without fully understanding what was being edited...

Actually, it sounds like you do have issues. But, that radio isn't supported by Chirp, so it's not surprising. I'd try using the OEM software.

I think it’s too late for OEM software. Looks like somehow CHIRP was able to jam in a lot of features that aren’t compatible with the CDM 750 radios. Trunking being one of them.

Does anyone have a code plug for this CDM750 AAM25SKC9PW1AN radio? I know that there are samples in the folder but that is failing as well. I just want to see if a good working code plug that someone in this forum has would work

you didn't save a known good one before you violated it with CHIRP?

If the samples aren't working, I'd be wondering if a firmware flash might save you...

I received it like this. I'm trying to find a firmware version to download but I have had no luck
