Hey guys, I have one BCT15, 2 BCT15X, and 1 BCD996XT.
In terms of programming, adding a few channels by direct entry should be fairly simple. I use an older program called FREESCAN, which links directly up to the RadioReference database. (You need a subscription) but it is worth its weight in gold!!!!! It makes programming complete systems very very easy. For example, I can upload every channel from CYYZ into one "bank" and just scan through it.
Try downloading Freescan, you may find it very easy!
