Yea, right. And what about the number 125...What's that for?!?

Here is the (recent) history of BC models.
BC72XLT - 100 Channels, Not PC Programmable
BC75XLT - 300 Channels, PC Programmable
BC92XLT - 200 Channels, Not PC Programmable, 800MHz
BC95XLT - 200 Channels, PC Programmable, 800MHz
BC125AT - 500 Channels, PC Programmable, Alpha Tagging
The 72, 92, and 95 all came out in the early 2000s (I think...) and the 75, and 125 came out in 2012.
At first it seems odd that the 75 would come out so long after the 95, but the numbering seems somewhat logical. 7 is for non 800MHZ, 9 is for 800MHZ. The 2 is for Non-Programmable, and the 5 is for PC Programmable. (Well, that seems to be the pattern at least.)
It isn't quite as easy to guess what the numbers mean on the 125, because its the only model BC model with a three digit number. I would assume that the 5 still means that it is PC Programmable.
The 75 features are very similar to that of the 72, 92, and 95, while the 125 is very different.
And as far as what the the XLT means, no idea.
