DXXX which is already how I know a lot of folks like myself note DPL anyway.
The leading zero is already built in! :)
My vote for the T convention is to stick with something beginning with T,
even if you use TCOR or T000. I think the dataset looks better with all the
repeaters lined up.

Now THAT is really is forward-looking thinking. Cool.....
Now to throw a monkey wrench into the works:
How do we accomodate DCS (Digital Coded Squelch) a.k.a DPL ("Digital PL
- Motorola) a.ka. DCG (Digital Channel Guard - GE) a.k.a DCTS (Digital Coded
Tone Squelch - Icom) into this scheme???
More and more of the newer radios can now encode/decode the 100+ DCS codes
that actually superimposes a continuous stream of digital data, at about
131baud, on the transmitted signal instead of a simple sine wave
single CTCSS tone. Sooner or later, we are going to see repeaters
going to DCS. Though most likely mostly closed systems with a small group
of hard core "techie" members.
