Just to add to what the others have said, when you're holding on the control channel on a Type 2 system, information about the system/site will scroll on the screen. You should see "SID:822Fh-0009" or something similar on the display. I've attached what I see on my 996XT when holding on a Zone 1 CC on Site 6 for reference. Your BCT15X should show similar. Are you 100% positive you programmed the bandplan correctly?
They should be:
"Custom"
Band Plan 1: Base Freq: Lower: 141.015 / Upper: 143.985 / Spacing: 15K / Offset: 380, + Polarity
Band Plan 2: Base Freq: Lower: 151.730 / Upper: 152.510 / Spacing: 15K / Offset: 579, + Polarity
Band Plan 3: Base Freq: Lower: 154.320 / Upper: 156.225 / Spacing: 15K / Offset: 632, + Polarity
Have you tried using an app like FreeScan or ProScan to program the scanner?
