You are confusing the 780 with the 785. The 780 is strictly analogue,
the 785 has the option of installing a card for digital reception. The
796 can do both analogue and digital, no need for an optional card.

It looks like the addition of an APCO BCi25 chip isn't possible with the
BC780XLT. I had been told it was, and someday planned to get one, but
now it seems that my best bet is to try and trade my two BC780XLTs for a
BC796D. Am I mistaken, can that chip indeed be inserted into my BC780XLT
to provide D-A audio conversion? I remember a conversation a couple
years ago with a tech support person from Uniden in Ft. Worth telling me
there was a socket in there, but when I looked the other day I couldn't
find it.
