[Elecraft] fldigi for Mac / K3 / KX3 / K2

[Dauer, Edward]

Fumbling with the Aether logging program during the recent CQ WW WPX (CW)
convinced me that I need to bite the bullet and get a program that will do
rig control as well as logging.  Posts on this reflector suggest that
fldigi is widely used, and it does seem to be usable with a Mac OS.  So I
downloaded the Users Manual.  It comprises 428 pages of dense computer
jargon, including a TOC of 18 pages, beginning with instructions about
configuring a sound card.  Two questions.  First, I operate 100% CW and I
don¹t care at all for machine decoding of CW received though I do want the
program to key my transmissions using info from the keyboard log entry -
call signs, automatic S/N update, other exchange, etc..  Do I even need a
sound card to use the fldigi program?  Second, is there a Cliff¹s Notes
version of the operating guide accessible by computer-speak tyros?  Tnx,
