No, they're incomplete.  Heil dynamic microphones (HC4, HC5,
HC5.1, HC6, "Classic", etc. elements) should not have DC.
*However*, Heil 'iC' elements *must* have DC (bias).

The Heil/Elecraft Proset K2/K3 is the same as the Heil
Proset iC (Icom) - the only difference is the use of the
AD1K (Kenwood adapter) versus the AD1I (Icom adapter).
