[Elecraft] CBLP3y Cable P3 to K3 connection

[Don Wilhelm]

Mike,

DE-9 is the proper designation for what most call the DB-9 connector.
The proper "DB" designation is for the wide 25 pin size housing that was 
used for printers on the PC and on commercial modems.
When the IBM PC first came out, they used 9 pin connectors for the 
serial ports and many referred to them as DB-9 even though the proper 
designation for that size connector (no matter how many pins) is "DE".
