[Elecraft] Connecting P3 to a K3

[Alan Bloom]

An RS-232 Y cable is needed for a device like a SteppIR antenna, which 
receives but does not transmit data on the RS-232.  The Y goes in the 
connection between the P3 and the computer.

The P3 comes from Elecraft with a short serial cable, coax IF cable, and power cable for the K3 back panel RCA 12V connector.
