[Elecraft] Remote operation of the K3 questions

The internet did not provide any answers to the above questions
because the configuration proposed is not feasible.  The P3
requires access via RS-232 to the K3 CAT commands and access via
the KXV3 or KXV3A to the receiver IF.  This means the P3 must be
collocated with the K3.  However, the display (and controls) is not 
"remoteable" nor is there a "slave" P3/0 equivalent to a K3/0.

There are, to the best of my knowledge, no off the shelf internet
remote operating systems that support the P3.

The standard solution for your needs - used my many many amateurs -
is to locate the equipment at the control point and use a large
diameter (7/8" or 1 5/8") hardline with a remote antenna switch
(generally with N+1 control lines where N=number of antenna ports).

73,
