[Motorola] field programmable radios?

[Jeff Kenyon]

Hi guys it's been while.  I was just wondering how easy is it to set up
radios so that they can be programmed in the field?  A while back I came
across a YouTube video where someone was field programming an old XTS-5000
and I think it may have been a model II.  They were using the keys to point
to the numbers they  wanted  to use to program the radio.  I would imagine
that with a model III with the full keypad you can type in what you want?
Before the video, I had always been under the impression that they couldn't
be programmed from the field at all.
