I saw this advertised in the latest QST: Powerwerx DB-750X Dual Band VHF/UHF 750 Channel Commercial Mobile Radio - on sale for $299.99.

The manual is here (PDF). I've yanked the whole description from the Powerwerx page:

  3. Hi, I have now a Polmar DB-50M but switched to MODE1 it becomes a Powerwerx.
    Does anyone has a menu number list of al functions?
    There is not such a list in the manual.
    If someone has a list, I would like to have it.
