It looks like IWN has updated their modified their P25 band plan on (I believe) 7/1/2024. I have a P25 data file from DSDPLUS from 6/7 and the old plan was still in effect. So, my best educated guess is that they shifted the plan at that time.
Be aware that this might affect your scanning of the IWN system. It's best to reload your codeplugs and make sure you don't have any saved information. Let the scanner auto-detect the P25 band plan and it should work fine.
