[Elecraft] K3/100 Assembly - KSYN3 Installation

[Matt Zilmer]

Hi Walter, 

Don't know OBTW but on some male connectors unused pins are cut to use
as keys.  I don't recall this being one of them, however.  There is no
easy way to plug the KSYN3 in backwards but it's possible the key is
added to keep the connector from being misaligned   If there is a
keyplug inserted into the matching female pin hole, then this is
certainly a key pin.  

Elecraft doesn't screw up things like this.  Pins 3 and 6 are n/c, so
it's likely your cut pin is pin 3, and it's being used as a key. Check
your schematics to be sure that it's pin 3, then move on.

Oh yes.  Welcome to K3-ness.  You'll feel better shortly.

73,

Looking at the figure on page 50, it is the third pin from the right, top row. The pin comes off the PCB, bends and enters the plastic, but it is missing on the other side (pins that insert into J73), close to the plastic portion of the plug.  Just a tiny bit of the pin shows, not enough to insert into J73 at all.

Soooo......can anybody please provide the missing clue so I can proceed with confidence or contact Elecraft.  Thanks much.
