Indeed, and news just in - it turns out to be the SMS communicator.

 

The antenna groundplane was bonded to DC negative, the antenna ground was screwed into the case via the mounting nuts, hence a path from DC negative to earth via the panel casing conducting through the SMS communicator antenna.
