I'll have to start reading to find out what the "object ID" actually is - whether it's something similar to a channel number or not.
The object ID is essentially a memory location where you enter information about a SYSTEM, CONVENTIONAL freq, SEARCH range, etc. There are roughly 1800 objects available.
When you enter the information through the PSR500 UI, the ID is automatically assigned. I'd like to believe it's one-up but I don't think that is the case. I'm not sure what the logic is for 'object ID' assignments through the UI. If you keep adding "objects", I think the objectId is just the next available "higher" ID so they appear in the radio based on when you entered it (last one is at the end of the list).
However, software in development like Don Starr's (starrsoft.com) Win500 program allow you to "select" the objectID you want to use for "objects" that you program (limited of course to unused objects). Right now, the software assigns the next "available" object ID but it allows you to change it to something else.
I've already used Win500 to change the object IDs for the AA County TRS such that the fire talkgroups are all in order - just to see how it would work... it's a bit tedious but it can be done with the software today.
I've been in touch with Don and I understand that in a future version of Win500, you'll be able to select an option that not only allows you to "sort" in the software on TGIDs or talk group names, it will also allow you to reassign the objectIds to keep them in that order in the radio itself...at least, that is what I believe he said.
Right now, the objects appear in the radio in order of their object ID so whatever was added last most likely will be at the end of the objectID list (unless you deleted something before adding something new - then it might stick it in that empty slot and not at the end).
