That is not correct.  The EA3BLQ "Digital Interface" board (K2DI v. 3)
provides a buffered/amplified signal from J5 (demodulator output before
the volume control).  This is the definition of a "line out" signal.

While not quite the same as Tom's board (Don's design), the EA3BLQ
"K2DI" board is functionally identical on receive and provides for PTT
microphone switching/muting that is missing in Don's design.  The
K2DI board can be used on a stand alone basis if one does not need the
"digital mode VOX" (e.g. "tone switching") or transformer input/output
isolation provided in the K2DI-PCI daughter board.
