ecm and diacom help needed

[Bruce Plecan]

There are two very similiar 8D masks, as I recall the F Bod, and the Y Bod.
It would sound like the one scanner is using the correct version, and the
other is being entered wrong, or there is an error in the diacom, which as
long as the 730 has used them sounds at least odd
